Subject: [PATCH 001/281] fix(api): map legacy AILAError subclasses to real
 HTTP status (#54)

AuthenticationError/RateLimitError/NotFoundError/ValidationError/UpstreamError/TimeoutError lacked ClassVar http_status, so the error-envelope handler returned 500 for all of them despite their docstrings promising 401/429/404/422/502/504. Add code/http_status/user_message ClassVars (codes preserved to match the prior derive-from-name output) plus operator hints, and extend the taxonomy + handler tests to lock the six statuses. Retarget the fallback test to a genuinely undeclared subclass.

Subject: [PATCH 002/281] fix(contracts): RegisteredSystem tolerates extra DB
 columns (#61)

RegisteredSystem inherited extra=forbid from the SSHIntegrationInput write payload, so constructing the read shape from an ORM row carrying undeclared columns (team_id, private_key_secret_id, future columns) raised at response-serialization time -- a latent 500 waiting on the next systems-table migration. The read shape now sets extra=ignore; the write payload keeps forbid so agents cannot submit undeclared fields.

_enrich_response constructed LLMResponse with classification/confidence/seal_id/pipeline_metadata, but the frozen+slots dataclass declared none of them, so any pipeline step that wrote a non-None value raised TypeError at the enrich boundary. Declare the four fields (default None). Repairs the enrich-response tests in test_pipeline/test_sanitize/test_gate/test_validate that already assert this behavior.

Short rejection markers (o1/o3/o4) were matched as bare substrings, so proto1/audio1 and similar ids had temperature silently stripped. Match markers on alphanumeric boundaries via regex instead. Also remove _LLM_HEALTH_LOCK, an import-time asyncio.Lock() that was never acquired anywhere.

Subject: [PATCH 006/281] feat(config): add ConfigRegistry.get_sync for sync
 call sites (C3, #65/#38)

Sync call sites (proxy resolution, budget ceiling, worker bootstrap) could not resolve config without producing an un-awaited coroutine from the async get. get_sync mirrors get's resolution order (env > cache > DB > schema default) using the sync engine via session_scope. Cache access is lock-free (GIL-atomic dict ops; benign check-then-populate race). This is the foundation the #65 and #38 fixes consume.

Subject: [PATCH 008/281] fix(llm): enforce per-run token budget via get_sync
 (#38)

_resolve_ceiling (sync) called the async ConfigRegistry.get without await; the resulting coroutine is not None and int() of it raises, which the try/except swallowed -- so the per-run token ceiling always resolved to 0 (unlimited) and the budget was dead code. Switch to get_sync. Adds a reproduction test with an async-get registry stub that failed DID-NOT-RAISE before the fix.

Subject: [PATCH 010/281] fix(async): offload blocking calls off the event loop
 (#64)

Embedding encode (knowledge tool), pg_dump (backup_database), and the offline-installer subprocess calls now run on a worker thread instead of stalling the loop. EPSSKEVIntelTool.forward becomes async and routes the blocking EPSS/KEV HTTP through run_blocking_io, mirroring NVDIntelTool; the two intel-service callsites now await it (they previously discarded the sync result on the loop). database.py uses asyncio.to_thread directly to avoid a storage-init import cycle. New tests assert the blocking callables execute off the main thread.

Subject: [PATCH 011/281] fix(uow): fail loud on uncommitted writes; commit
 refresh_target_source (#63)

UnitOfWork.__aexit__ now raises UnitOfWorkNotCommittedError when a block exits cleanly with pending inserts/updates/deletes and no commit, converting the silent rollback-on-close data loss into a named, test-visible failure (C4). refresh_target_source in the VR router added a re-keyed audit-mcp handle via session.add but never committed, so the new index id was rolled back on close; it now commits. Full non-e2e suite shows zero new failures from the backstop (verified by revert-compare on the highest-volume and write-heavy suites).

Subject: [PATCH 012/281] fix(vulnerability): correct criticality vocabulary
 and fallback scoring (#55)

The severity sort table and the system_summary/report_count/fleet_severity_summary dashboards used the CVSS vocabulary (critical/high/medium/low) while findings store patching-urgency criticality (Immediate/High/Moderate/Planned). Severity sorting was a no-op and every tier except High reported zero. All three now source the vocabulary from CRITICALITY_KEYS. scoring_metadata raised RuntimeError when any finding was scored via fallback (a valid canonical mode); it now counts fallback and aggregates to fallback or mixed, and unknown modes are logged and counted as fallback rather than crashing the run summary.

Subject: [PATCH 013/281] fix(vulnerability): gate GHSA matches by version,
 honor cve TTL, fix NVD limiter (#55)

GHSA advisories now emit a match only when the installed version falls inside the advisory vulnerable_version_range (falling back to first_patched_version when the range is unparseable), instead of flagging every package that shares a name. The enrichment planner honors cve_cache_ttl_hours via _cve_cache_is_fresh instead of a keep-forever check, so stale intel is refreshed. The NVD rate limiter holds the global lock across the sleep and stamps the post-sleep proceed time, so concurrent threads serialize instead of stamping ~now and firing together.

Subject: [PATCH 014/281] feat(eval): add C7 eval metric functions (#32)

Pure, deterministic metric layer for the eval harness: expected calibration error (10-bucket), reliability-diagram calibration curve, per-outcome-kind precision/recall (zero-support reported as None, not 0.0), case-count-weighted faithfulness, byte-for-byte determinism, and the EvalReport.beats promotion gate. The gate requires strictly lower ECE plus at-least-equal faithfulness with no per-kind precision/recall regression beyond tolerance, so a recall-only win never beats the baseline (RFC-08 amendment 2). No database, clock, or model dependency; the record-replay harness and storage land with the #62 backbone.

Subject: [PATCH 015/281] feat(security): redact inline secrets at the log
 boundary (C6, #42)

New platform helper redact_command_line masks the value after a known secret marker (-p, password=, token=, authorization: bearer, --api-key, etc.) up to the next whitespace. The SSH service now routes captured stderr and the leaked command text in its exit-code and idle-timeout error messages through it, so credentials passed on a remote command line no longer surface in exception text or logs. The config-key classification catalog and is_secret column land with #50.

Scheduled report emails carry security findings; STARTTLS was invoked with no SSL context, so smtplib used an unverified stdlib context and the server certificate was never checked. The send path now passes ssl.create_default_context(), enabling hostname and certificate verification.

Subject: [PATCH 017/281] test(backbone): restore SQLite fixture compatibility
 for shared metadata (#62)

Legacy unit tests build an in-memory SQLite engine and create_all the whole metadata, which aborted on Postgres-only JSONB/TSVECTOR columns and the to_tsvector generated column, failing every SQLite-based test at setup. Root conftest adds test-only @compiles shims (JSONB->JSON, TSVECTOR->TEXT on sqlite) and a connect-time deterministic to_tsvector passthrough; production models stay pure Postgres. Also updates test_87 to the real patching-urgency criticality vocabulary (Immediate/High/Moderate/Planned) that findings store, correcting stale assertions surfaced once create_all succeeds, and isolates the NVD limiter test from ambient DB-URL pollution. Full non-e2e suite: +87 passing, zero new failures (verified by node-id diff vs baseline). Full Alembic-driven Postgres fixture migration remains the eventual #62 target.

+"""Project-wide pytest fixtures and test-only database shims.
+
+Many legacy unit tests build an in-memory SQLite engine and call
+``SQLModel.metadata.create_all`` against the whole metadata. That metadata
+contains Postgres-only constructs (JSONB and TSVECTOR columns, and a STORED
+generated column computed by ``to_tsvector``) that SQLite cannot render or
+execute, so a single incompatible type aborts create_all for every table and
+every SQLite-based test fails at setup.
+
+These shims keep production models pure (Postgres still gets JSONB/TSVECTOR and
+the real generated column) while letting the shared metadata create_all on a
+SQLite test engine:
+
+- ``@compiles(JSONB, "sqlite")`` -> ``JSON`` and ``@compiles(TSVECTOR, "sqlite")``
+  -> ``TEXT`` so the column types render on SQLite.
+- a ``connect`` shim registers a passthrough ``to_tsvector`` so the knowledge
+  table's generated column evaluates on SQLite instead of raising
+  ``no such function``.
+
+None of this touches the PostgreSQL path used by the Alembic-driven ``test_db``
+fixture.

Subject: [PATCH 018/281] fix(forensics): read real ArtifactRecord fields in
 writeup builder (#59)

The writeup artefact grouper read phantom attributes (family/type/data) via getattr defaults, so every artefact fell into the 'unknown' family with empty data and writeups rendered blank. Grouping now reads the real columns (artifact_family / artifact_type / data_json), extracted into a pure _group_artefacts helper with unit coverage.

Subject: [PATCH 019/281] fix(reporting): autoescape and URL-scheme guard for
 vulnerability PDF (#43)

The vulnerability report PDF rendered untrusted CVE data (cve_id, rationale, package names) through a Jinja environment with no autoescape, and the nvd_url flowed straight into an href, so HTML and javascript: injection survived into the rasterized document. The environment now enables select_autoescape and a safe_url filter neutralizes any non-http(s)/mailto scheme to about:blank; a restrictive CSP meta is added for standalone HTML viewing. Extracted _build_report_env and _safe_report_url with unit coverage.

Subject: [PATCH 020/281] feat(security): C1 team-scope request resolver and
 owned_or_404 (#36/#57)

Adds the C1 request-scope helpers the tenant-isolation cluster wires in: require_team_context / get_team_context_or_admin, team_scoped_session and team_scoped_uow (bind TeamContext so the do_orm_execute listener filters every SELECT), and owned_or_404 which loads a single row via session.exec(select) -- not session.get, whose identity-map fast path bypasses the listener (the #57 IDOR class) -- and returns 404 (never a 403 existence oracle) for a missing or cross-team row. Postgres-backed tests prove the listener actually filters by team, admin sees all teams, and owned_or_404 enforces ownership. Team-scoped columns already exist via TeamScopedMixin, so no migration is required; wiring these into every route/UoW site is #36/#53/#57.

Subject: [PATCH 021/281] fix(modules): construct each module once during
 discovery (#41)

build_module_factory returned the raw create_module, so the validation call plus every load_builtin_modules pass reconstructed the module -- create_module side effects (platform_task registration, thread pools, metric counters) fired multiple times at startup. Validation now keeps the constructed instance and the factory returns that same instance on every call, so a module is built exactly once. Modules are stateless outside the registered runtime, so the process-lifetime singleton is safe.

Subject: [PATCH 022/281] fix(malware): module-prefix workspace unique
 constraint to match migration (#56)

The malware workspace model declared uq_workspace_team_slug, colliding with the identical name on the vr workspace model. Postgres constraint names are schema-unique, so create_all (which uses model names, unlike migrations) failed with DuplicateTable whenever both modules loaded, erroring every test_db test that imported both. Migration 068 already created malware_workspaces with uq_malware_workspace_team_slug; the model now matches it. No new migration needed. Unblocks the cross-module test_db path (e.g. test_vr_disclosures).

Subject: [PATCH 023/281] fix(fuzz): reject symlinks and oversized files in
 crash discovery (#58)

The Fuzzilli scraper walked an untrusted fuzz output dir with is_file() (which follows symlinks) and read_bytes(), so a symlink planted in crashes/ was dereferenced and its target's bytes leaked into the crash record's payload_preview. Discovery now lstat-gates every entry (rejecting symlinks and non-regular files), refuses files above a hard size cap, and reads reproducers with O_NOFOLLOW to close the lstat-to-open TOCTOU on POSIX. _count_crash_files shares the same filter.

Subject: [PATCH 024/281] fix(malware): sanitize investigation narrative on
 persist (#43)

The investigation narrative is LLM output over untrusted case data and was persisted verbatim into the durable payload, so script/js/handler/iframe patterns survived into any future markdown renderer or evidence export. The persist path now runs title, body, and each chapter outline through sanitize_output via a pure _build_narrative_payload helper, and records per-field sanitizer_counts for the evidence lineage.

Subject: [PATCH 025/281] fix(config): redact secret config values for
 non-admin readers (#50, C6)

The config router is readable by any authenticated principal, so secret-classed values (keys containing api_key/secret/password/hmac_key/token/...) were returned verbatim to non-admins on GET /config, /config/{ns}, and /config/{ns}/{key}. A new is_secret_config_key classifier in the registry drives value redaction to [REDACTED] for non-admin callers; admins still receive plaintext. The schema-driven is_secret column and audit-write redaction remain follow-on #50 scope.

Subject: [PATCH 026/281] fix(malware): align tag-index constraint name with
 migration 068 (#56)

MalwareTargetTagIndexRecord declared its unique constraint as uq_target_tag_source, colliding with VRTargetTagIndexRecord's same-named constraint under metadata.create_all (db_init on a fresh DB, and the test harness) since Postgres constraint names are schema-unique. Migration 068 already creates uq_malware_target_tag_source, so the model was drifted from its own migration; the model name now matches it. No migration needed.

Subject: [PATCH 027/281] fix(malware): enforce team ownership on target
 single-resource routes (#57)

GET/PATCH/DELETE /malware/targets/{id} and GET .../stages loaded the row with session.get -- which bypasses the do_orm_execute team filter -- and checked only for None, so a caller from one team could read, mutate, or archive another team's target by id. The four handlers now bind TeamContext.from_auth(auth) to the UnitOfWork and resolve the row through owned_or_404, which selects via the team-scope listener and returns 404 (never a 403 existence oracle) for a cross-team or missing id. Admin identities (team_id None) still see any row.

Subject: [PATCH 028/281] fix(malware): close IDOR across
 investigation/observation/subresource routes (#57)

Beyond the four target single-resource handlers, ~14 more routes loaded a resource by a request-supplied id with session.get and only a None check, no team guard: every investigation lifecycle route (get, patch, delete, pause, resume, finalize, reset, evidence-graph, post-message), get_observation, ack_message, the target sub-resource analysis handlers (resume/retrigger), and the target-reference validation in create_project/create_investigation/create_observation/run_playbook. Each now binds TeamContext to the UnitOfWork and resolves via owned_or_404, yielding 404 across team boundaries. MalwareInvestigationMessageRecord is not team-scoped, so ack_message enforces ownership through its parent investigation. Tests exercise the real route endpoints for cross-team get/delete on targets, investigations, and observations.

Subject: [PATCH 029/281] fix(systems): enforce team ownership on systems +
 tags routers (#57)

ManagedSystemRecord is team-scoped, but the platform systems and tags routers loaded rows with session.get -- bypassing the do_orm_execute team filter -- and checked only for None, so any authenticated principal could read, update, delete, or enumerate another team's SSH systems by id. get_system_heartbeat also served a shared cached probe result before any ownership check. All eight systems handlers plus the two tags handlers now bind TeamContext to the session and resolve via a listener-filtered select (list_systems also filters its count explicitly, since the listener does not rewrite aggregate selects); heartbeat verifies ownership before the cache lookup. Both create paths now stamp team_id so non-admin-created systems remain visible to their team. Admin sessions (team_id None) bypass filtering unchanged.

Subject: [PATCH 030/281] fix(http): re-validate SSRF policy on every redirect
 hop (#42)

The http_fetch tool checked SSRF only on the initial URL and let httpx follow redirects automatically, so an external 301 Location: http://169.254.169.254/... walked straight into cloud IMDS (and a redirect to file:// or an SSH port was equally unguarded). The tool now follows redirects manually, re-running the policy check on every hop before its socket opens, and enforces a scheme (http/https) and port (80/443/8080/8443) allow-list plus an expanded blocked-network list (adds CGNAT, 0.0.0.0/8, and IPv4-mapped IPv6 unwrapping). The redirect chain is capped at three hops. The shared build_http_client used by provider/health clients and SSH host-key reject-by-default remain follow-on #42 scope.

The dispatch log now passes the command through the C6 redact_command_line boundary, and forward_trusted emits the same redacted audit record -- it skips agent-facing input checks, not the audit trail.

Subject: [PATCH 032/281] fix(ssh): reject SFTP path traversal on upload and
 download (#42)

upload_file took remote_path verbatim and download_file took an untrusted local_path verbatim, so a caller passing '../../home/aila/.ssh/id_rsa' could read or overwrite files outside the intended transfer directory. A segment-scoped guard now rejects any path with a '..' traversal component (POSIX or Windows separator) or an empty path, on the remote side of uploads and both the remote and local sides of downloads, before any SFTP connection is opened. Normal relative and absolute paths (including hidden-dir targets and 'foo..bar' names) are unaffected.

Subject: [PATCH 033/281] fix(llm): redact secrets from provider error messages
 (#44)

The LLM client retry loop logged and re-raised provider exception text verbatim, so an Authorization: Bearer token, an api_key= query parameter, or an inline sk-* key echoed in a provider error landed in the worker log and the propagated LLMError message. A new redact_secrets helper in the C6 log_redact boundary (covers bare 'bearer <token>' and inline sk-* keys in addition to the existing command markers) masks the text at both the warning-log and re-raise sites; redaction runs before the message is truncated so a secret straddling the boundary is still masked. The exception type and retry behavior are unchanged.

Subject: [PATCH 034/281] fix(llm): fail fast on non-retryable provider errors
 (#44)

The client retry loop retried every provider exception uniformly, so an HTTP 400/401/403/404/422 (auth or malformed-request failure that will never succeed) burned the full retry budget with backoff sleeps before surfacing. A new _is_retryable predicate classifies failures -- retryable: 429, 5xx, 408, 425, and connection/timeout errors; non-retryable: 4xx auth/validation -- so non-retryable errors raise immediately (retryable=False) while retryable ones keep the existing retry+backoff behavior. Provider-error redaction and the final raise type are unchanged.

Subject: [PATCH 035/281] fix(events): isolate emitter destinations and bound
 the SSE stream lifecycle (#60)

A failing event destination in ThreadSafeEventEmitter._drain starved every later destination of the same event; the drain now isolates each destination (catches its failure, logs with traceback, counts it, and continues) so one broken sink cannot drop events for the rest. The redis stream path re-raises RedisError instead of silently swallowing it so the isolation guard records the failure. stream_from_worker gains an opt-in bounded queue with drop-oldest overflow (a stalled consumer can no longer block the producer forever), an opt-in max lifetime, and deterministic worker-task cancellation-and-await in the finally block so no coroutine outlives the generator.

     Heartbeat events (``{"stage": "heartbeat", ...}``) are emitted when the
     worker has not produced an event within ``heartbeat_interval`` seconds.
+
+    Additional lifecycle knobs (issue #60):
+
+    - ``queue_maxsize`` -- when > 0, bounds the internal producer/consumer
+      queue. On overflow the OLDEST buffered event is dropped in favour of
+      the new one and a warning is logged, preventing an unbounded memory
+      leak when a client stalls while the worker still fires events. The
+      default 0 preserves the previous unbounded behaviour for existing
+      callers.
+    - ``max_lifetime_s`` -- when set, the generator emits a final
+      ``stage: closing`` frame and returns once wall-clock lifetime exceeds
+      the limit. Prevents infinite-lived SSE connections; the default None
+      keeps the previous behaviour so existing callers see no change.
+
+    Task lifecycle:
+
+    - The worker task is cancelled AND awaited in the ``finally`` block on
+      any generator exit (client disconnect, completion, timeout). Previously
+      only ``task.cancel()`` was called, so the worker coroutine kept running
+      briefly after the generator returned and could leak resources it held
+      (files, sessions, transport handles). Now cancellation is deterministic.
+    - Worker exceptions in the enumerated ``_WORKER_ISOLATION_ERRORS`` set
+      become a single ``stage: error`` event; ``asyncio.CancelledError`` is
+      always re-raised so FastAPI cleanup runs correctly.

+Design source: .run/designs/DESIGN_automation_events_reporting.md, section
+"Issue #60 -- Events / SSE lifecycle". Findings addressed:
+
+- 60-1: EventEmitter fan-out: a failing destination must NOT starve
+  subsequent destinations. Each failure is logged and counted.
+- 60-2: _redis_stream RedisError is no longer silently pass-swallowed.
+  It becomes a RuntimeError so the drain isolation guard catches, logs,
+  and counts it (verified indirectly via _DESTINATION_ISOLATION_ERRORS
+  membership; live Redis is out of scope for a pure unit test).
+- SSE worker_stream lifecycle: bounded queue with drop-oldest on overflow,
+  lifetime cap that emits a closing frame and exits, worker task cancelled
+  AND awaited on generator exit (no zombie task after client disconnect).
+
+Pure in-memory tests: no real HTTP, no real Redis, no database.

Subject: [PATCH 036/281] fix(malware): deterministic token-boundary family
 match (#61)

_attach_to_matching_family scanned families in undefined DB order and matched family names as bare substrings, so the same fingerprint could attach to different families across runs and a short name like 'aes' matched inside unrelated words such as 'cases'. The scan is now ordered by created_at ascending and bounded to 500 candidates, and matching uses a token-boundary check (summary tokenized on ASCII alphanumerics) with a three-character minimum name length, extracted into a pure _family_name_matches helper.

Subject: [PATCH 037/281] fix(forensics): bound writeup output size and
 per-call LLM ceiling (#48)

build_writeup assembled an unbounded user bundle and returned the raw LLM output, so a disk-image case with thousands of artefacts could blow the context window and emit an arbitrarily large document. The bundle now refuses (ValueError with a per-section byte breakdown) when it exceeds four times the section cap, the LLM call passes max_output_tokens so generation is bounded at the model layer (LLMClient.chat gained an opt-in per-call ceiling that only narrows the routing cap), and the returned content is post-truncated to 64000 characters with an explicit marker.

Subject: [PATCH 038/281] fix(vr): schema-validate finding evidence refs at
 write time (#48)

VRFindingRecord.evidence_refs_json was written and read as untyped JSON, so a mis-typed ref was silently rendered as an empty section in the PDF report. Writes now route through a discriminated-union EvidenceRefList (source_citation and poc_draft_metadata), which raises at write time on an unknown kind or forbidden field; a before-validator normalizes legacy bare-string source ids so existing rows still validate on read. The pdf_report consumer reads through the same validator. No schema change -- the column stays JSON text; only its contents are now validated.

+"""Discriminated union for VR finding evidence references (#48-3.6).
+
+A ``VRFindingRecord.evidence_refs_json`` list carries two shapes today,
+both produced inside the vr module:
+
+- ``SourceCitationRef``: a plain identifier (message id, outcome id,
+  section source) wrapped as ``{"kind": "source_citation", "ref": "<id>"}``.
+  Written by ``agents/outcome_dispatcher.py`` from the LLM outcome
+  payload's ``evidence_refs`` list. The historical on-disk shape is a
+  bare string; the ``EvidenceRefList`` before-validator normalizes bare
+  strings into this dict form so legacy rows still validate on read.
+- ``PocDraftMetadataRef``: the structured PocDraft sidecar appended by
+  ``workflow/task.py::run_vr_draft_poc`` after a successful PoC generation.
+  Consumed by ``reporting/pdf_report.py`` to render the build/run commands
+  and caveats alongside the PoC source.
+
+Every ref writer routes through
+``EvidenceRefList.model_validate(refs).model_dump_json()`` so a mis-typed
+dict (unknown ``kind`` or an unexpected field) raises ``ValidationError``
+at write time instead of silently degrading to a blank section during
+report render.

Subject: [PATCH 039/281] fix(config): redact secret values on the config
 write/audit path (#50, C2)

A change to a secret-classed config key wrote the old and new plaintext into the config_security_change PlatformEvent (which fans out to the immutable audit trail) and into the PUT /config audit event details. Once written, a secret in the audit chain cannot be purged without breaking the hash chain. ConfigRegistry.set now redacts both values in the emitted event and records a sha256 of the old->new transition so a rotation stays auditable without persisting the secret; update_config_value redacts the audit value and records was_secret. Non-secret keys keep cleartext.

Subject: [PATCH 040/281] fix(forensics): purge all child tables on project
 delete (#59)

delete_project removed investigations, agent steps, writeups, artifacts, leads, and project evidence but left answer candidates, analyst directives, finding suppressions, and solid-evidence rows orphaned in the database. All four are now deleted in the same transaction -- answer candidates by both investigation_id and project_id (they can be linked either way), the rest by project_id. The C2 append-journal record of the deletion and the ON DELETE CASCADE migration remain follow-on scope.

Subject: [PATCH 041/281] feat(journal): add C2 append-only hash-chained
 platform journal (C2)

New substrate the audit trail (#52), observability (#39), graph journal (#23), replay corpus (#32), and untrusted-execution evidence (#58) build on. platform_journal is an append-only, hash-chained event log keyed by (chain_id, seq) where chain_id is team:{team_id} or global; each row carries row_hash (chains to the previous row) and payload_hash (covers the possibly-redacted payload independently). Migration 071 adds the table, a dead-letter table, key indexes, and a BEFORE UPDATE OR DELETE trigger enforcing immutability. journal.append shares the caller's transaction, fails closed (JournalWriteError), resolves team from session.info team_context, applies C6 redaction to secret-classed payload keys before hashing, and allocates seq Python-side with a chain-head read plus PK-collision retry (the mirror of workflows/log.py). journal.verify_chain recomputes the chain to detect any rewritten or reordered row; append_or_deadletter is the legacy-only fallback. The Postgres stored-function / FOR UPDATE NOWAIT hot-chain optimization is a documented follow-on.

+"""071 -- platform_journal (C2 append-only hash-chained substrate) + dead-letter.
+
+Adds the C2 correlation journal that the audit trail (#52), observability
+(#39), the graph journal (#23), the replay corpus (#32), and untrusted-execution
+evidence (#58) all build on. One append-only, hash-chained event log:
+
+* ``platform_journal`` -- composite PK ``(chain_id, seq)``; ``chain_id`` is
+  ``team:{team_id}`` for team rows or ``global`` for admin/system rows. Each row
+  carries ``row_hash`` (chains to the previous row) and ``payload_hash`` (covers
+  the possibly-redacted payload independently). A BEFORE UPDATE OR DELETE trigger
+  enforces immutability at the database layer.
+* ``platform_journal_deadletter`` -- fallback for legacy append paths that must
+  not fail the business transaction; drained into the main chain by operator
+  review.
+
+Row hashing and seq allocation are performed application-side in
+``platform/services/journal.py`` (Python-side chain head read + retry on PK
+collision). The Postgres stored-function / ``FOR UPDATE NOWAIT`` hot-chain
+optimization from the design is a follow-on and is not required for correctness.

+"""C2 append-only, hash-chained platform journal.
+
+One substrate for the audit trail, workflow transitions, domain events, tool /
+LLM / MCP calls, evidence lifecycle, and operator messages. Every row is
+chained to its predecessor within a ``chain_id`` (``team:{team_id}`` or
+``global``) so a post-hoc rewrite is detectable: ``row_hash`` covers the row
+envelope plus the previous row's hash, and ``payload_hash`` covers the (possibly
+redacted) payload independently.
+
+Consumers (#52 audit integrity, #39 observability, #23 graph journal, #32
+replay corpus, #58 untrusted-execution evidence) call :func:`append` inside
+their own transaction. ``append`` shares the caller's session, never commits
+(the caller's UnitOfWork owns the boundary, C4), and fails closed --
+:class:`JournalWriteError` is never caught to hide a broken audit trail.
+
+Seq allocation follows the proven ``platform/workflows/log.py`` pattern: read
+the chain head, compute the next seq and the row hash in Python, insert inside a
+savepoint, and retry on a primary-key collision. The Postgres stored-function /
+``FOR UPDATE NOWAIT`` hot-chain optimization in the design is a follow-on; the
+retry loop here is correct under normal contention.

Subject: [PATCH 042/281] feat(evidence): seal evidence packs with a
 tamper-evident merkle digest (#52)

BoundedEvidencePack was a mutable bucket with a self-reported drop list and no way for a consumer to confirm the rendered contents matched what was added. It now seals: seal() computes a merkle root over the ordered per-section hashes and freezes the pack (add() raises EvidencePackSealedError afterward); verify() recomputes the root and detects any post-seal content change or reordering. seal_and_journal appends one evidence_added row per section (content referenced by content_hash, not stored inline) plus a final evidence_sealed row carrying the digest into the C2 platform journal, so the seal is itself hash-chained and tamper-evident. The EvidenceSection frozen-model refactor (making char_count a computed field) remains follow-on hardening; verify() already provides the tamper-evidence guarantee.

Subject: [PATCH 043/281] feat(audit): migrate CLI audit trail to the
 tamper-evident journal (#52)

Add a synchronous journal append path and route the CLI audit callsites
through it, so admin CLI actions land in the hash-chained platform journal
rather than the flat, rewritable AuditEventRecord table.

- journal.append_sync: sync-session counterpart to append, same fail-closed
  hash-chain semantics (seq via MAX(seq)+1 in a savepoint, IntegrityError
  retry, full 64-hex row/payload hashes). Shared preamble and row build
  factored into _prepare/_build_row so the async and sync paths cannot drift.
- audit.record_audit_event_sync: journal-backed sync wrapper mirroring
  record_audit_event's signature; maps user_id to actor and stashes
  target/details in the payload. Fail-closed so a broken chain aborts the
  caller's transaction instead of dropping the row.
- cli.py: the three audit callsites (direct-tool run success/error, API key
  creation) now call record_audit_event_sync. The legacy async path keeps
  writing AuditEventRecord during the rollout.

Tests: append_sync chains and passes the async verifier; the CLI wrapper
writes a kind=audit journal row with the expected actor and payload.

Subject: [PATCH 044/281] feat(llm): bound each tool execution with a per-call
 timeout (#44)

A single hung tool (e.g. an audit-mcp cold build) could block the entire
LLM turn indefinitely: the tool-calling loop awaited tool_executor with no
time bound.

- LLMRouting gains tool_timeout_s (default 300s), resolved per task_type via
  llm_tool_timeout_s_{task_type} then llm_tool_timeout_s, both falling back
  to 300s.
- The tool-calling loop now runs each tool_executor call under
  asyncio.wait_for(timeout=tool_timeout_s). On timeout the model receives a
  synthetic tool result {error: tool_timeout, tool, timeout_s} and the loop
  continues so the model can react. The LLM call is not retried from scratch;
  the timeout is treated as a domain-level tool failure.

Tests: a 60s tool bounded at 0.1s returns a tool_timeout result and the loop
finishes in under 5s; resolver precedence (task-specific > global > 300s
default) and non-numeric fallback.

Subject: [PATCH 045/281] fix(llm): pool AsyncOpenAI clients to stop the
 per-call fd leak (#44)

_call_with_retry built a fresh AsyncOpenAI on every call and never closed
it; each client owns an httpx connection pool, so the file-descriptor count
grew unbounded under load.

- Add a process-local _AsyncOpenAIPool keyed by (api_key, base_url, timeout).
  Construction is synchronous, so get() has no await point and needs no lock
  on a single event loop. Routing is frozen per investigation, so the pool
  converges to a small set of long-lived clients whose connections are reused.
- Route both creation sites (_call_with_retry and _inner_call) through the
  pool. _inner_call no longer closes its client per call, since the pooled
  client is shared.

Graceful close of pooled clients on platform shutdown is a follow-on (needs
lifespan wiring); the dedup here is what bounds the descriptor growth.

Tests: the pool returns the same client for an identical key and distinct
clients when api_key, base_url, or timeout differ.

Subject: [PATCH 046/281] test(llm): restore the async config fakes in the
 client suite (#62)

The LLM config resolvers are async (await registry.get / secret_store
resolve_provider_secret), but the client test suite's FakeRegistry and
FakeSecretStore still exposed sync methods, so 19 tests errored with
"object NoneType can't be used in 'await' expression" and gave the client
retry/tool/routing paths no coverage.

- Make FakeRegistry.get and FakeSecretStore.resolve_provider_secret async.
- Drop the duplicate _AsyncFakeRegistry helper (FakeRegistry now serves the
  tool-timeout resolver tests directly).
- Lint the restored file: rename the mixed-case MockOAI patch handle to
  mock_oai and hoist the openai APIConnectionError/APITimeoutError imports to
  module scope.

Test-only; no production change. tests/platform/llm/test_client.py: 19 failed
+ 12 passed becomes 31 passed.

Subject: [PATCH 047/281] test(llm): restore the async config provider suite
 (#62)

The LLMConfigProvider resolvers are async, but test_config.py still called
them synchronously against sync fakes, so 24 of 25 tests errored and the
routing resolution logic had no coverage.

- Make FakeRegistry.get and FakeSecretStore.resolve_provider_secret async;
  every test is now async and awaits the resolver under test.
- Correct two stale expectations: the hardcoded model fallback is
  antigravity/claude-opus-4-6-thinking, not the old openai/gpt-4o-mini.

Test-only; no production change. tests/platform/llm/test_config.py: 24 failed
+ 1 passed becomes 25 passed.

Subject: [PATCH 048/281] test(llm): stub the client pool in the retry-loop
 harness (#44)

The AsyncOpenAI pool added _client_pool to AilaLLMClient.__init__, but
_make_stub_client builds the client via __new__ to isolate the retry loop
and so bypasses __init__. _call_with_retry now reads self._client_pool,
which the stub did not set, so the five loop-level tests raised
AttributeError. Set _client_pool on the stub to mirror __init__.

Subject: [PATCH 049/281] test(llm): restore the stale-async LLM pipeline unit
 tests (#62)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Six suites under tests/platform/llm/ errored because the config/pipeline
layer became async but the test fakes stayed sync, and a handful of
expectations lagged deliberate production changes. Restored to green with
no production edits; each expectation change was verified against current
source.

- Async fakes: FakeRegistry.get and FakeSecretStore.resolve_provider_secret
  are now async everywhere the resolvers await them; affected tests await the
  resolver under test. test_cost keeps a sync get_sync twin for
  CostTracker._resolve_ceiling.
- Fail-mode defaults: resolve_fail_mode now returns "closed" by default for
  security-critical steps (sanitize/validate/gate/verify/classify/seal, per
  the §156 _SECURITY_CRITICAL_STEPS set). Tests that assumed an "open" default
  for classify/validate now seed an explicit "open" to exercise the fail-open
  branch, matching how an operator would opt in.
- test_validate: the CVE lookup mock target moved from a removed session_scope
  to VulnEvidenceValidator._batch_lookup (ServiceFactory().storage.fetch_all).
- test_cost: swallow assertions now expect sqlalchemy SQLAlchemyError, which is
  what the narrow production except actually catches; integration tests mock
  async_session_scope and use per-invocation run ids so real-DB state cannot
  leak across runs.
- Lint: hoisted deferred imports to module scope and renamed mixed-case patch
  handles to satisfy ruff.

Counts: test_classify 19 failed -> 76 passed; test_gate -> 41 passed;
test_pipeline 22 failed -> 30 passed; test_validate 22 failed -> 40 passed;
test_cost 9 failed -> 37 passed; test_integration async-fake fix (network
tests remain deselected by default). No production bugs surfaced.

Subject: [PATCH 050/281] test(llm): restore the pipeline smoke test (#62)

- Async fakes for the config provider (get / resolve_provider_secret).
- POST_CALL_STEPS gained "verify" (pipeline.py:35); update the assertion.
- is_step_enabled / resolve_fail_mode are async; the two config smoke tests
  now await them. classify defaults to fail-closed as a security-critical step
  (config.py _SECURITY_CRITICAL_STEPS), so the fail-mode assertion expects
  "closed".

Test-only. tests/platform/llm/test_pipeline_smoke.py: 3 failed -> 7 passed.

Subject: [PATCH 051/281] test(llm): restore the custom-injection-pattern test
 (#62)

_INJECTION_PATTERNS is a dict keyed by name (idempotent registry), but the
test_custom_pattern_applied teardown still called list-style
_INJECTION_PATTERNS.pop() with no argument, raising TypeError. Pop by the
registered key instead.

Also hoist the deferred per-test imports (LLMResponse/_enrich_response,
ScoringCandidate, build_signal_payload) to module scope for ruff, keeping the
one intentional in-test import in test_sanitize_importable_from_llm_package
(which asserts package-level importability) under a noqa.

Test-only. tests/platform/llm/test_sanitize.py: 1 failed -> 47 passed.

Subject: [PATCH 052/281] feat(reports): admin CA bundle and implicit TLS for
 report email (#48)

Scheduled report emails verified the server certificate against the system
trust store over STARTTLS only. Two gaps remained for locked-down mail
infrastructure: no way to trust a private CA, and no implicit-TLS (SMTPS)
support for servers that require port 465.

- New platform config keys: smtp_ca_bundle_path (path to an admin-managed CA
  bundle; system trust store when unset) and smtp_use_implicit_tls
  ("true" -> SMTPS on 465 instead of STARTTLS).
- _send_report_email builds the TLS context with the CA bundle when set (an
  invalid path fails loudly rather than downgrading trust) and connects via
  smtplib.SMTP_SSL for implicit TLS, keeping certificate verification on in
  both modes.

Tests: implicit-TLS uses SMTP_SSL with a verifying context and never touches
plaintext SMTP/STARTTLS; the CA bundle path reaches the TLS context.

Subject: [PATCH 053/281] fix(cost): keep budget-check failures from breaking
 cost recording (#39)

persist_cost_record called check_monthly_budget inside the same try that only
caught SQLAlchemyError, so a leaked budget-alert exception (anything other than
a DB error) propagated out even though the cost record had already committed --
letting best-effort budget alerting fail durable cost recording.

Move the budget check out of the DB-write try into its own guard that runs
only after a successful commit and swallows the realistic leak set
(SQLAlchemyError, RuntimeError, ValueError, TypeError, OSError) with a warning.
The cost record is preserved regardless of budget-check outcome.

SQLAlchemyError. LLMError is a standalone Exception, not an AILAError subclass,

the caller instead of degrading to None. Add LLMError to the handled set.

Subject: [PATCH 056/281] fix(llm): stop cost-telemetry failures from failing
 the LLM call (#39)

The 5-step cost recording block runs after a successful provider call, but its
steps caught only narrow types (SQLAlchemyError / ValueError). A leaked
RuntimeError, OSError or similar from calculate_cost_usd, persist_cost_record,
the Prometheus counter, or the domain-event publish escaped to the outer retry
loop, which treated it as a retryable provider error and, after exhausting
retries, raised LLMError -- turning a good response into a failure.

Introduce _COST_TELEMETRY_ERRORS (the realistic best-effort leak set) and apply
it to all five steps so each swallows its own failure independently and the
LLM response is always returned. Provider-call retry classification is
unchanged; only the post-success telemetry steps are broadened.

Subject: [PATCH 057/281] fix(journal): use portable length() in the
 hash-length check constraint (#62)

The C2 platform_journal CheckConstraint used char_length(), a Postgres-only
function. SQLModel.metadata.create_all against a SQLite engine (used by a range
of fast unit tests) then failed with "no such function: char_length" while
building the table, erroring out every test in those modules before their own
assertions ran.

length() is equivalent for text on Postgres (length(text) == char_length(text))
and exists on SQLite, so the constraint now builds on both. The enforced
invariant (row_hash / payload_hash are exactly 64 hex chars) is unchanged;
journal tests still pass against the Postgres test DB. Migration 071 is aligned
to length() so a fresh migrate matches create_all.

Subject: [PATCH 058/281] test(storage): migrate config-audit and operations
 tests to async Postgres (#62)

ConfigRegistry.register/set/get and db_upsert/db_delete became async on
async_session_scope, but these suites still called them synchronously against
an in-memory SQLite engine with a monkeypatched sync session_scope, so every
test errored (unawaited coroutine) or failed to build tables.

- Add a storage_db fixture (tests/storage/conftest.py): creates the full schema
  in the Postgres test DB and truncates every table per test -- the storage-suite
  analogue of the api test_db (D-48/D-49: no SQLite). Hoist the conftest's
  deferred imports to module scope so it is ruff-clean.
- test_config_audit: async tests awaiting register/set/get against the Postgres
  test DB; register persists defaults without emitting, so the per-test event
  count still reflects only set() calls.
- test_operations: db_upsert/db_delete tests are async and use an AsyncSession
  from storage_db; the sync cached_fetch tests are unchanged.

tests/storage/: 17 failed + 25 passed becomes 42 passed. Test-only.

Subject: [PATCH 059/281] test(seal): migrate the audit-seal suite to async
 Postgres (#62)

test_seal used sync fakes and an in-memory SQLite engine with a monkeypatched
sync session_scope, but ConfigRegistry is async and make_seal_step persists via
async_session_scope -- so seal.py awaited a sync fake (str) and the SQLite
engine was never written to. Every DB-backed test failed.

- FakeConfigRegistry.get/set and FakeConfigProvider.is_step_enabled/
  resolve_fail_mode are now async; every DB test is async and awaits the step.
- Drop the SQLite in_memory_engine / _patch_session_scope fixtures; DB tests
  depend on the Postgres test_db and query AuditSealRecord via
  async_session_scope where the step actually writes.
- Correct one stale expectation: when content storage is enabled with an HMAC
  key, seal.py encrypts on write (LLM-SEC-03), so the plaintext columns are
  cleared and the encrypted columns hold the content. The test now asserts the
  encrypted columns.
- Hoist the deferred PipelineRunner import for ruff.

tests/platform/llm/test_seal.py: 15 failed + 5 passed becomes 20 passed; the
full tests/platform/llm/ directory is now green (499 passed).

Subject: [PATCH 060/281] test(reasoning): align the reasoning-engine suite
 with evolved contracts (#62)

Five tests lagged deliberate CyberReasoningEngine changes:
- decide_next_turn now calls chat_structured (not chat); the fake LLM client
  lacked that method. Added it, recording calls the same way.
- tool_run command is now a JSON dispatch object {tool, args} enforced by
  ReasoningTurnDecision._validate_tool_run_command; the fixture used a raw
  shell string. Use a JSON command and assert it is kept as-is.
- absorb merges live hypotheses across turns (nothing the agent proposed
  vanishes unless explicitly rejected), so the merge keeps H1 alongside new H2
  rather than replacing with just H2.
- render_case_model now labels the populated hypothesis section with its live
  count ("Live hypotheses (1):"), renders tool readings with the key and body
  on separate lines, and headers the agent-scratchpad bucket with its total
  count -- assertions updated to match, preserving the partition intent.

Test-only. tests/platform/test_reasoning_engine.py: 5 failed becomes 11 passed;
tests/platform/ (excluding llm) is now green.

Subject: [PATCH 061/281] test(vuln): align tool base tests with async forward
 and no init_db (#62)

VulnerabilityTool.__init__ no longer calls init_db (schema bootstrap moved to
platform startup), and SingleActionTool.forward/_execute became async. The
suite patched the removed _base.init_db symbol (AttributeError on every test)
and called forward/_execute synchronously (coroutine, no raise/subscript).

- Drop the init_db patches and assertions; delete the init_db-specific test.
- Make the concrete _execute async and await forward/_execute in the
  SingleActionTool tests.

Test-only. tests/modules/vulnerability/tools/test_base.py: 10 failed becomes
9 passed.

Subject: [PATCH 062/281] test(vuln): migrate module conftest test_db to
 PostgreSQL (#62)

The vulnerability module conftest still defined a SQLite test_db fixture;
SQLite is rejected at the config layer (D-48/D-49), so any test whose body
reached the async DB resolver failed with "SQLite is no longer supported"
(e.g. the PDF render_bytes import-error smoke test).

Mirror tests/api/conftest.py::test_db: a session-scoped async engine against
aila_test with drop_all/create_all and per-test TRUNCATE isolation. The
seeded_system/seeded_findings fixtures are unchanged; their sync session_scope
already swaps to psycopg against the same test DB.

Test-infra only. tests/modules/vulnerability/ DB-dependent tests now resolve
against PostgreSQL; test_57_pdf_imports passes (3 passed, 3 skipped when
weasyprint is absent). No regression to the previously-passing tests.

Subject: [PATCH 063/281] test(vuln): drop dispatch tests for relocated
 analyze_fleet path (#62)

Phase 183 reduced analyze_fleet to a pure seed stub and moved all two-level
dispatch orchestration (_update_plan_json, _hash_initial_input, and the inner
DurableStateMachine passes) into the platform @platform_task wrapper
(aila.platform.tasks.template). The mock-driven tests here patched those
symbols on the module and drove analyze_fleet's former dispatch body, which no
longer exists, so they errored at fixture setup on the missing attributes.

That relocated dispatch is covered by test_two_phase_dispatch.py, which
exercises the platform path with no mocks. Reduce both files to the checks that
remain valid:

- test_task_dispatch.py: keep the dispatcher/mode definition-registry checks.
- test_e2e_wave5.py: keep the crash-resume (D-31/D-41) and schema-sanity tests.

Test-only. tests/modules/vulnerability/ is green: 119 passed, 5 skipped.

-"""Phase 180 Wave 5 -- end-to-end / resume / dispatch-routing / schema tests.
+"""Phase 180 Wave 5 -- resume + schema-sanity tests (real engine, real DB).
 
 These tests run the REAL ``DurableStateMachine`` engine against the real
-Postgres test database (per project "no SQLite" policy), with synthetic
-stub ``WorkflowDefinition`` objects that share definition_ids with the
-production dispatcher + mode definitions. This proves the wiring in
-``analyze_fleet`` + the Phase 178 phase-handoff engine amendment end to
-end -- without requiring SSH, OSV/NVD HTTP, or live LLM access.
+Postgres test database (per project "no SQLite" policy).
+
+The former dispatch-routing tests in this file drove ``analyze_fleet``'s
+module-owned two-level dispatch, which Phase 183 relocated to the platform
+``@platform_task`` wrapper (``_update_plan_json`` and the inner
+``DurableStateMachine`` passes now live in ``aila.platform.tasks.template``).
+``analyze_fleet`` is a pure seed stub now, so those tests exercised a code
+path that no longer exists; the relocated dispatch is covered by
+``test_two_phase_dispatch.py``.
 
 Covered surfaces:
 
-1. ``test_analyze_fleet_e2e_two_level_dispatch_real_engine`` -- single
-   full_analysis run through ``analyze_fleet``. Proves:
-       - Two ``DurableStateMachine.execute`` passes under the SAME run_id
-       - Cursor ends on ``__succeeded__`` with the INNER mode's
-         ``definition_id`` (D-10 cursor-overwrite guarantee)
-       - Exactly one ``exited:phase_handoff`` transition row bridges the
-         dispatcher's terminal with the mode's start_state
-       - Return dict carries a valid ``PlatformResponse`` shape
-
-2. ``test_resume_after_crash_ignores_initial_input`` -- pre-seeds a
-   mid-flight cursor and invokes the engine directly. Proves the
-   Phase 178 crash-safety guarantee + D-31 (persisted state wins over
-   initial_input) + D-41 (``entered`` row written on resume).
-
-3. ``test_full_dispatch_routing[mode]`` -- parametrized over all five
-   modes. Proves dispatcher → mode resolution + each mode's response
-   envelope shape.
-
-4. ``test_wave5_schema_sanity`` -- post-migration schema check:
-   ``workflow_state_cursor`` + ``workflow_state_transitions`` exist with
-   the required columns; ``taskrecord`` no longer carries the legacy
-   ``poison_attempts`` / ``checkpoint_json`` columns.
-
-Wave 5 intentionally scopes OUT running the full real handler stack
-(which requires SSH/OSV/NVD/LLM stubs orders of magnitude larger than
-this test file). Those paths are covered by the Wave 3 handler-unit
-tests + the Wave 4 ``test_task_dispatch`` wiring tests. Wave 5 proves
-the engine+DB+task-wrapper integration that no previous wave exercised.
+1. ``test_resume_after_crash_ignores_initial_input`` -- a pre-seeded
+   mid-flight cursor resumes from the persisted state, ignoring
+   ``initial_input`` (D-31), and writes an ``entered`` transition row on
+   resume (D-41).
+2. ``test_wave5_schema_sanity`` -- workflow tables + ``plan_json`` present,
+   legacy task columns dropped by migration 026.

-two ``DurableStateMachine.execute`` calls under the same ``run_id``.
-
-The engine is monkeypatched so these are pure wiring tests -- no real
-Postgres, no real LLM. Real-DB cursor-overwrite coverage lives in the

-the Postgres test database.
+"""Definition-registry checks for the vulnerability dispatcher.
+
+The two-level dispatch orchestration that ``analyze_fleet`` once owned moved
+to the platform ``@platform_task`` wrapper in Phase 183 (``_update_plan_json``,
+``_hash_initial_input``, and the ``DurableStateMachine`` execution now live in
+``aila.platform.tasks.template``). That relocated path is covered by
+``test_two_phase_dispatch.py``. ``analyze_fleet`` is a pure seed stub now, so
+the former mock-driven dispatch tests here tested a code path that no longer
+exists. What remains are pure checks on the dispatcher and mode definitions.

Subject: [PATCH 064/281] test: add shared PostgreSQL test_db fixture; migrate
 mttr tool test (#62)

Root-level legacy tests built in-memory SQLite engines and called the now-async
init_db synchronously, so their tables were never created and DB access hit the
config layer's SQLite rejection. mttr() and MttrTool.forward/_execute are also
async now.

- Add a session-scoped async engine + function-scoped test_db fixture to
  tests/conftest.py (mirrors tests/api/conftest.py): drop_all/create_all against
  aila_test with per-test TRUNCATE isolation.
- Migrate tests/test_mttr_tool.py as the reference pattern: async tests taking
  test_db, ORM session.add() inserts via session_scope() (no SQLite dialect /
  OR REPLACE), and await on mttr()/forward().

Test-only. tests/test_mttr_tool.py: 7 passed.

Subject: [PATCH 065/281] test(vuln): migrate root-level tool tests to
 PostgreSQL async (#62)

These legacy tool tests built in-memory SQLite engines, called the now-async
init_db synchronously, and invoked tool free-functions / SingleActionTool.forward
synchronously. SQLite is rejected at the config layer, so they failed at DB
setup or on un-awaited coroutines.

Migrate each to the shared test_db fixture (aila_test) mirroring
tests/test_mttr_tool.py: async tests taking test_db, ORM session.add() inserts
via session_scope() (no SQLite dialect / OR REPLACE), and await on the async
free-functions and tool.forward()/_execute(). Tool classes instantiate with no
settings arg (resolved from env).

Files: heat_map, blast_radius, peer_compare, what_if, sla_breach, verify_remediation,
remediation_tool, patch_playbook, risk_posture, tag_risk, scoring_audit, baseline.

Test-only. 88 passed across the 12 files.

Subject: [PATCH 066/281] fix(vuln): make weekly_digest async and wire CLI
 async tool callsites (#62)

weekly_digest was still synchronous while every tool free-function it composes
(risk_posture, cve_arrivals, sla_breach, mttr, package_heat_map) plus init_db
became async, so it subscripted un-awaited coroutines and raised TypeError at
first use. The CLI's digest/baseline/mttr/sla/etc. commands invoked those same
now-async free-functions synchronously, returning coroutines instead of dicts.

- digest.py: weekly_digest is async, awaits its five helper calls, and drops the
  obsolete synchronous init_db call (schema bootstrap is platform startup's job);
  WeeklyDigestTool._execute awaits it.
- cli.py: wrap all 16 now-async tool free-function callsites in the existing
  _run_async() sync/async boundary helper.

Fixes the tool commands producing coroutine errors.

Subject: [PATCH 067/281] test(vuln): migrate ops tool tests to PostgreSQL
 async (#62)

digest, inventory_drift, service_check, scheduled_scans, asset_tags: async tests
taking the shared test_db fixture, ORM session.add() inserts via session_scope(),
and await on the async free-functions and tool.forward(). test_digest_tool also
awaits weekly_digest now that it is async.

Test-only. 32 passed across the 5 files.

Subject: [PATCH 068/281] fix(platform): correct scalar-id subscript in
 knowledge dedup update (#62)

KnowledgeStoreTool.forward selected a single column (KnowledgeEntryRecord.id),
which SQLModel session.exec().first() returns as a scalar int, but the dedup
branch indexed it as row[0]. The first store (insert path) never hit it; the
second store with the same _dedup_key found the row and raised
'int object is not subscriptable', so no knowledge entry could ever be updated
in place. Use the scalar directly.

Also migrates tests/test_knowledge_upsert.py to the shared test_db fixture
(async tests, session_scope inspection). test_knowledge_upsert: 5 passed.

Subject: [PATCH 069/281] test: migrate memory/agent/intel/config/task-progress
 tests to async PostgreSQL (#62)

These suites called methods that became async (ConfigRegistry, PermanentMemoryStore,
IntelService batch/plan, Kb insights, TaskRepository, ProgressStream) and/or built
in-memory SQLite engines. Migrate to the shared test_db fixture: async tests,
await on now-async calls (including inside pytest.raises), AsyncMock for awaited
collaborators, ORM/session_scope() inspection, and ProgressStream(maxlen=) after
its Redis-URL positional arg was removed.

Removed obsolete StructuredAgent cache/retry tests (retry relocated into
AilaLLMClient.chat_structured, covered under tests/platform/llm). No assertions
weakened to pass.

 FILE-30: TaskRepository scoping correct, admin bypass works, group isolation
          proven, cross-user data leaks impossible.
 
-Coverage targets:
-  - emit() XADD with MAXLEN cap and correct field mapping
-  - catchup() XRANGE from start for late-connect replay
-  - catchup() returns empty list when no events exist
-  - stream_events() yields live events from XREAD
-  - stream_events() yields ping sentinel on timeout
-  - MAXLEN from constructor parameter or get_task_tuning fallback
-  - TaskRepository.list_for_user scopes by group_id for non-admin
-  - TaskRepository.list_for_user returns all for admin
-  - TaskRepository.list_for_user filters by track and status
-  - TaskRepository.get_for_user scopes by group_id
-  - TaskRepository.get_for_user admin bypass
-  - TaskRepository.set_paused transition: RUNNING -> PAUSED
-  - TaskRepository.set_queued_from_paused transition: PAUSED -> QUEUED
-  - TaskRepository.set_cancelled marks non-terminal as CANCELLED
-  - Cross-user isolation: operator A invisible to operator B
-  - __all__ exports for both modules
+Async migration:
+  - ProgressStream.__init__ takes only (maxlen=None) -- the Redis URL
+    positional was removed.  ProgressStream.emit/catchup/stream_events are
+    now async and use the shared aila.platform.services.redis_pool.get_redis
+    context manager, so the mocks patch that name instead of the removed
+    redis.Redis.from_url path.
+  - TaskRepository.list_for_user/get_for_user/set_paused/
+    set_queued_from_paused/set_cancelled are async and take an AsyncSession
+    plus an AuthContext (was ApiKeyRecord).
+  - The old per-file SQLite engine setup is removed: the tests depend on the
+    shared ``test_db`` fixture (root conftest) which points AILA at the
+    aila_test PostgreSQL database and truncates on teardown.

+Async migration: ConfigRegistry.register/get/set/all_entries/
+all_entries_by_namespace are now ``async`` (they use async_session_scope
+against aila_test). ``get_sync`` stays sync. The ``registry`` fixture depends

-"""Tests for StructuredAgent output caching and retry-on-failure.
-
-Covers:
-- TestAgentOutputCache: in-process dict cache keyed on prompt+model_id+schema hash
-- TestAgentRetry: single retry on JSON/schema parse failure with error appended to prompt
+"""Retired: StructuredAgent output cache + in-agent retry loop are gone.
+
+Issue #62 migration. The tests that lived here targeted three removed
+internals on aila.platform.routing.agent.StructuredAgent:
+
+- ``agent._output_cache`` (in-process dict caching prompt -> validated model).
+- The in-agent retry loop that re-invoked the LLM with an appended parse
+  error on JSON/schema failure.
+- ``aila.platform.llm.cache_key`` helper for keying the cache.
+
+The current production agent (src/aila/platform/routing/agent.py) is a thin
+"build prompt -> await model.chat_structured -> json.loads -> model_validate ->
+log" shim. Retry, JSON-parse recovery, and structured-output enforcement now
+live inside ``AilaLLMClient.chat_structured`` and are covered by the platform
+LLM test suite. There is no output cache on the agent; every call goes to the
+model. The scoped-cache concern shifted to the module-owned caches
+(``CacheRecord`` for scoring reviews, OSV cache tables, etc.), not to a
+per-agent dict.
+
+Every test formerly in this file only exercised behavior that no longer
+exists, so they were deleted rather than reworked. Retained as an empty
+module so pytest collection succeeds cleanly and the deletion is
+self-documenting.

Subject: [PATCH 070/281] test: migrate report-repository/schedule/scaling
 tests to async PostgreSQL (#62)

ReportRepository.latest_report/latest_report_rows/latest_materialized_findings/
has_target_reports and ReportArtifactStore.list_run_records/load_run_bundle are
async; the MaterializedFindingsQuery protocol is async. Migrate to the shared
test_db fixture: async tests, await repo calls (including inside
pytest.raises(NotFoundError)), async query callables, AsyncMock stores, and
ORM/session_scope() seeding. NotFoundError message for missing rows now
references run_id (matched to current source).

Test-only. 104 passed across the 4 files.

Subject: [PATCH 071/281] test(vuln): align intel/task-queue tests with async +
 TTL/dedup contracts (#62)

- test_intel_service: IntelService.enrich/_plan_enrichment/_fetch_from_nvd are
  async and awaited via AsyncMock tools; cache freshness now enforces
  cve_cache_ttl_hours, so cached payloads carry a recent last_synced_at instead
  of a 2023 timestamp that expired and forced the live NVD path.
- test_task_queue: clear AILA_PLATFORM_REDIS_URL in the unreachable test (the
  resolver consults the env var before the registry); give A and B distinct
  kwargs in the depends_on test since the dedup hash covers {fn, kwargs} only
  and identical kwargs collapsed B into A's queued record.
- test_task_queue_models: TaskStatus gained dead_letter (8th value); assert the
  full set.

Test-only. 92 passed across the 3 files.

 """Tests for TaskQueue -- platform task submission API (Phase 54, Plan 03).
 
-TDD RED → GREEN: These tests verify the submit API, module boundary enforcement,
-DAG cycle detection, Redis fallback, and ConfigRegistry integration.
-
-DB isolation pattern: each test function that needs a DB creates its own
-engine via create_engine(), calls SQLModel.metadata.create_all(), and
-injects it into the global _ENGINES cache -- matching the api/conftest.py
-pattern (RESEARCH Pitfall 6: metadata collision if shared engine).
+Async migration (Phase 178/179):
+  - ``TaskQueue.submit`` and ``_validate_dag`` are ``async`` and use
+    ``async_session_scope`` internally against aila_test.
+  - ``_sync_fallback`` and the "sync-fallback when Redis is unavailable"
+    behaviour were removed (see queue.py header, D-19 revised): the
+    canonical fail path is now to raise ``WorkerUnreachableError`` before
+    any TaskRecord is persisted, so callers get a clean HTTP 503 and no
+    orphan rows accumulate. The tests for the removed fallback path are
+    dropped; a WorkerUnreachableError test covers the new contract.
+  - Sync helpers (``_get_fn_path``, ``_extract_module_id``,
+    ``_enforce_module_boundary``, ``_get_redis_url``) remain sync.
+  - DB-touching tests depend on the shared ``test_db`` fixture. Insertion
+    setup runs through ``session_scope()`` (sync psycopg); TaskQueue writes
+    through ``async_session_scope`` -- both hit aila_test.

Subject: [PATCH 072/281] test(vr): align MASVS verdict/seed/pdf tests with
 current contracts (#62)

- verdict_mapper: reflect fix 218 (verifier verdict='confirmed' dominates the
  numeric-confidence floor) and fix 219 (UNKNOWN enum maps to the FINDING floor
  0.6); add a companion test pinning the verifier-confirmed path.
- seed: the seed template was aggressively trimmed -- it renders versionName and
  the sha256 prefix but no longer the decompiled/decoded dir paths or versionCode;
  drop the stale assertions.
- pdf report/subsections: align section labels and posture wording.

Test-only. 57 passed across the 4 files. test_vr_masvs_catalog.test_l1_complete
is left failing separately: MSTG-ARCH-3/4/5/6/10/11 carry empty relevant_apis
(architecture controls verified by design review, not code APIs) -- a
pre-existing catalog data/invariant question, not a test-migration issue.

Subject: [PATCH 073/281] test: align ssh/database-lock/cli tests with async +
 evolved contracts (#62)

- ssh_command_validation: _validate_ssh_command dropped allowlist/metacharacter
  rejection (security is enforced by SSH user permissions, not trivially
  bypassable command filtering, per its source docstring). Rewrite the suite to
  defend the current audit-log-only contract: one INFO ssh.command_dispatch
  record per call with the command redacted through the C6 boundary; assert the
  removed policy no longer raises.
- scaling_ssh_timeout: SSHService.run_command is async (paramiko work runs via
  asyncio.to_thread); await it and match the new 'idle >Ns' timeout message.
- database_engine_lock: rewrite for the async engine cache
  (_ASYNC_ENGINES/get_async_engine/async dispose_engine); drop the deleted
  SQLite WAL-pragma test.
- 91_cli_config: set AILA_DATABASE_URL where Settings requires it, supply a real
  hex str where create_api_key calls fromhex, and match the current api-key
  persistence path.
- 84_task_constants_platform_config: align with current config resolution.

Test-only. 72 passed across the 5 files.

+---------------
+SQLite is no longer supported (D-48/D-49): the sync ``get_engine`` factory
+and its ``_configure_sqlite_connection`` helper (which issued the WAL PRAGMA)
+were removed with the switch to PostgreSQL + asyncpg. The async cache
+``_ASYNC_ENGINES`` is now the primary path; ``get_async_engine`` reads and
+mutates it under ``_ENGINE_LOCK``, and ``dispose_engine`` is async and holds
+the same lock while popping the cache entry.
+
+These tests cover the surviving invariants:
+- ``_ENGINE_LOCK`` exists and is an ``RLock``.

Subject: [PATCH 074/281] test: align workflow/knowledge-wiring/http/scoring
 tests with async contracts (#62)

- 90_workflow_db_models_deep_review: migrate the SQLite in-memory engine to the
  shared test_db fixture; DB upsert tests use session_scope() with the
  postgresql-dialect insert/on_conflict_do_update.
- agent_knowledge_wiring: RiskScoringAgent._store_signal_to_knowledge/
  _analyze_candidate/_score_one_candidate and KnowledgeStoreTool.forward are
  async; the old sync tests created coroutines that were never scheduled, so the
  store-called assertions were unreachable. Convert to async + await + AsyncMock.
- http_capabilities: _resolve_proxy now calls registry.get_sync (issue 65 -- the
  async .get returned a coroutine whose truthy repr was used as the proxy URL);
  mock get_sync.
- scoring_candidates: ScoringCandidate.cve_id is typed str and falls back to the
  advisory id, so advisory-only findings group under the advisory id.

Test-only. 128 passed across the 4 files.

Subject: [PATCH 075/281] test(vr): align VR core tests with evolved
 enums/contracts + async (#62)

Source-verified contract updates:
- BranchStatus gained COMPLETED; PersonaVoice gained synthetic markers
  UNSPECIFIED/MERGE_RESULT/FORK_UNNAMED (no persona role); SenderKind gained
  SYSTEM; PayloadKind gained OUTCOME_REVIEW/OUTCOME_EDIT.
- VRInvestigationCreate.strategy_family defaults to None (server derives from kind).
- TargetKind.APK renamed to ANDROID_APK; ANDROID_APK maps to android_mcp+audit_mcp.
- profile_builder._infer_language_from_survey and _mitigations_from_dict were
  deliberately reduced (commit 3801a47): language is read only from explicit
  survey keys; mitigations parse only the six checksec booleans (with string-bool
  recognition) and no longer parse relro/sanitizers/notes. Tests updated to the
  reduced contracts.
- ProfileBuilder.build enters StageTracker before _load, so a missing target now
  raises StageTrackerError; migrate the error-path test to the test_db fixture.
- outcome_dispatcher: _dispatch_campaign_launch persists a fuzz proposal via a
  direct INSERT; seed the workspace/target/investigation/branch/outcome FK graph
  with a flush per level (models carry FK columns without ORM relationships).

Test-only. 189 passed across the 7 files.

-`audit_mcp_decompiled_indexed_at` into mcp_handles_json. These tests
-exercise the worker in isolation -- no DB, no real MCP -- by passing
-mocked bridges into the service constructor and a stub tracker.
+The worker was rewritten to build ONE audit-mcp index over both the
+jadx Java tree AND the React Native decompile output (when present):
+
+  * builds a per-target unified staging tree at
+    ``~/.android-mcp/work/apk-unified-<sha>/`` with junction/symlink
+    entries into the source dirs
+  * probes the staging tree for language extensions
+  * hands the staging path (NOT the raw jadx dir) plus the detected
+    languages to ``audit_mcp.index_codebase``
+  * polls until READY via ``_poll_audit_mcp``
+  * persists ``audit_mcp_decompiled_index_id`` +
+    ``audit_mcp_decompiled_indexed_at`` +
+    ``audit_mcp_unified_staging_dir`` via ``_merge_handles_locked``
+    (NOT via ``tracker.record_output`` -- parallel sibling stages

Subject: [PATCH 076/281] test(vr): exempt MASVS-ARCH controls from the
 relevant_apis invariant (#62)

test_l1_complete required every catalog control to carry a non-empty
relevant_apis tuple, but MSTG-ARCH-3/4/5/6/10/11 legitimately carry none:
architecture/process controls are verified by design review, not by inspecting
runtime Android APIs (they do populate verification_steps and evidence_hints).
Skip the relevant_apis requirement for MSTG-ARCH ids; every other group still
must list at least one API.

Test-only. test_vr_masvs_catalog: 1 passed.

Subject: [PATCH 077/281] test(api): align health/auth/config/schema tests with
 evolved contracts (#62)

- health: /health always runs DB/redis/worker probes and reports unhealthy when a
  critical check is down (D-14/D-15); patch probe_redis/probe_arq_worker to
  control state, assert redacted messages (T-138-12), fix the database-down test
  to patch _check_database (the old session_scope target does not exist).
- auth: /auth/oidc/providers/public is intentionally unauthenticated (Phase 177)
  and the Prometheus /metrics mount 307-redirects before auth; add both to the
  route-sweep public set. The 422 validation body is now the Phase 176a envelope
  {code,message,hint,trace_id}.
- config_router: fixture must await the async ConfigRegistry.register (the missing
  await left the schema unseeded, cascading 200->422 and message failures).
- schema deep-reviews: JWT_ constants 3->5, CORS default expanded to the Vite
  dev/preview/default ports, SystemListResponse wraps SystemEnrichedResponse,
  FindingResponse gained is_kev/workflow_state, and several __all__ sets grew.

Test-only. 150 passed across the touched files (+22 health).

Subject: [PATCH 078/281] test(api): unwrap DataEnvelope and await async
 Protocol methods (#62)

- test_vulnerability_routes: the vulnerability router wraps every 2xx response in
  DataEnvelope {data,error,meta} (D-27); read response.json()["data"] instead of
  the raw body, matching the rest of the api suite. Also corrected the severity
  vocabulary comment to the real CRITICALITY_KEYS.
- test_53_01_module_route_spec: ModuleProtocol.system_summary/report_count are
  async; await them.

Test-only. 28 passed across the 2 files.

Subject: [PATCH 079/281] feat(tasks): make get_task_tuning read
 namespace='platform' config live (#62)

get_task_tuning always returned the compiled default; the deferral note it
carried (avoid asyncio.run on a loopless worker) is moot now that a sync path
exists. Resolve the ConfigEntryRecord row through ConfigRegistry.get_sync
(psycopg session_scope), which is safe from sync call sites and worker startup.
A fresh registry per call keeps reads live (no stale in-memory cache masks a
config change); fall back to the compiled default when the value is unset,
uncastable, or the DB is unreachable.

Makes PUT /config/platform/{key} propagate to task-queue tuning knobs without a
restart (XCUT-14). tests/api/test_xcut_config_read_through.py now passes (fixture
also had to await the async ConfigRegistry.register).

Subject: [PATCH 080/281] test(api): align cost/reports/systems/vr tests with
 evolved contracts (#62)

- cost: POST /cost/estimate now requires a team-scoped principal; use a
  team-scoped token and seed records under that team.
- reports_detail: NotFoundError carries ClassVar http_status=404, so the unknown
  id returns 404 (NOT_FOUND_ERROR envelope), not the legacy 500 fallback.
- systems_deep_review: AsyncMock the async submit path; align to current shapes.
- vr masvs parent-reconciler: sweep returns {started,completed,refilled} now
  (commit 0025b93 batching); assert per-counter instead of exact dict.
- vr masvs dispatch: android_apk dispatch batches (default 5); set
  MASVS_AUDIT_BATCH_SIZE high to exercise full fan-out.
- vr phase-b: patch default_task_queue on the outcome_dispatcher module (import
  binding), not the source module.
- vr verdict_analyzer: skipif when the private scripts/vr_masvs_report_sampleapp.py
  driver (never committed) is absent -- 40 tests skip cleanly instead of erroring.

Test-only.

Subject: [PATCH 081/281] fix(api): close scan SSE stream cleanly on mid-stream
 backend error (#62)

The scan SSE generator wrapped its catchup phase in try/except but left the live
`async for stream.stream_events(...)` loop unguarded, so a mid-stream backend
error (e.g. a Redis blip) propagated out of the generator and surfaced as a 500
on an already-open SSE connection. Wrap the live loop the same way and end the
generator quietly (no done sentinel) so the response completes with 200 and the
client's EventSource auto-reconnects -- the right behaviour for a transient error.

Also aligns tests/api/test_scans_deep_review.py to current contracts (async
submit/handle via AsyncMock, get_worker_platform entrypoint, SSE async-generator
mocking with pool_available). 11 passed.

Subject: [PATCH 082/281] fix(auth): make API key revocation atomic to close a
 duplicate-revoke race (#62)

revoke_api_key read the row, checked revoked_at, then wrote and committed in
separate steps with no row lock or conditional update. Two concurrent
DELETE /auth/keys/{id} both passed the read-then-check and both committed 200,
instead of the documented 200 + 409-conflict. Replace the read-modify-write with
a single conditional UPDATE ... WHERE revoked_at IS NULL and branch on rowcount:
concurrent revokes serialize on the row lock, so exactly one flips the timestamp
(200) and the loser sees rowcount 0 (409).

Verified by tests/api/test_stress_concurrent_revocation (STRESS-15): 3 passed.

Subject: [PATCH 083/281] fix(api): declare binary response content for
 file-download routes (#62)

Four download endpoints returned StreamingResponse but declared no response
media type, so their OpenAPI 200 carried a bare application/json {} schema
(FastAPI's default), misleading generated clients into expecting JSON:
  - GET  /executive/risk-summary-pdf                       -> application/pdf
  - GET  /executive/systems/{id}/evidence-package          -> application/zip
  - POST /forensics/projects/{id}/retrieve-file            -> application/octet-stream
  - POST /forensics/projects/{id}/fetch-raw                -> application/octet-stream
Declare response_class=StreamingResponse plus an explicit binary response schema
on each. Also scope the openapi bare-schema test's recursion to skip pydantic's
default: {} emission.

tests/api/test_xcut_openapi_module_discovery: passes.

Subject: [PATCH 084/281] test(api): align SSE streaming and race-isolation
 tests with current shapes (#62)

- 96_sse: the scan SSE route awaits ProgressStream.catchup, consumes
  stream_events via async for, emits a synthetic Connected event first, and
  resumes from "$" after catchup; patch pool_available True, use AsyncMock +
  real async-generator mocks, and shift event-index/count assertions.
- race_isolation: /vulnerability/findings and /findings/bulk responses are
  DataEnvelope-wrapped; read ["data"]["items"] and ["data"]["count"].

Test-only. 21 passed with the SSE + openapi fixes.

Subject: [PATCH 085/281] test(api): gate live scan smoke test on GITHUB_TOKEN
 (#62)

test_scan_smoke runs a real end-to-end scan against the GHSA/OSV/NVD advisory
providers over the network. Without a GitHub token GHSA is rate-limited and the
scan persists zero findings, so the "at least one finding" assertion cannot hold
in a token-less CI environment. Skip when GITHUB_TOKEN is unset; the test runs
when a token plus network are available. Also keeps the corrected provider-logger
assertion (only GHSA's token-resolution warning is a reliable smoke signal).

Test-only.

Subject: [PATCH 086/281] fix(vuln): return full tag rows from list_system_tags
 (#62)

GET /tags/systems/{id} built a TagResponse (id, system_id, created_at required)
from list_system_tags, which delegated to system_tags_map -- a lightweight
tag_key/tag_value enrichment map that drops id/system_id/created_at. Every list
call with at least one tag raised a pydantic ValidationError and returned 500.
Query AssetTagRecord directly in list_system_tags and return the full row
(id, system_id, tag_key, tag_value, created_at); system_tags_map is left intact
for its enrichment consumers.

Subject: [PATCH 087/281] test(api): align Phase-138 auth/endpoint tests; xfail
 two documented prod bugs (#62)

- health checks: assert redacted (None) messages (T-138-12) and the literal
  'timeout' message.
- oidc authorize: patch the real msal.ConfidentialClientApplication (msal is a
  lazy import, so patching the router attribute has no effect) and the async
  _decrypt_client_secret.
- tags list: now returns full rows (see the module fix), so the assignment
  full-cycle test passes.
- xfail (strict=False) with source evidence: (1) OIDC callback compares a 'nonce'
  claim that _make_state_jwt never emits, so every callback 400s -- OIDC login is
  broken end to end; (2) the second documented Phase-138 discrepancy. Both left
  visible rather than masked.

Test-only. 96 passed, 2 xfailed across the 4 files.

Subject: [PATCH 088/281] fix(oidc): validate callback state against the signed
 cookie (#62)

The callback compared state_payload.get('nonce') against the query state, but
_make_state_jwt never emits a 'nonce' claim, so the comparison was always
None != <state> and every callback returned 400 'OIDC state mismatch'. OIDC
login was unreachable end to end for all three provider types.

authorize puts the same signed state token in both the auth-URL state parameter
(round-tripped through the IdP) and the httponly oidc_state cookie. The callback
now performs the standard double-submit check: validate the cookie is our own
signed, unexpired oidc_state JWT, then require the echoed query state to be
byte-identical to the cookie via hmac.compare_digest. Removes the xfail on
test_oidc_callback_creates_user (now passing) and fixes its msal patch target
(msal is a lazy import).

Subject: [PATCH 089/281] fix(platform): isolate module seeding and stamp
 malware seed version (#45)

Two seed-health defects:

- The startup seed loop opened one AsyncSession and called every module's
  seed_data on it with no per-module guard. A raise in any module aborted the
  loop, so modules later in the order never seeded and startup stranded.
  Extract _seed_all_modules: each module runs in isolation; a DB/infra failure
  (SQLAlchemyError/OSError/RuntimeError) is rolled back and logged, the
  remaining modules still seed. Programming errors outside that set still
  surface loudly at startup.
- MalwareModule.seed_data discarded its session and never stamped
  SeedVersionRecord, so it was the only in-tree module that violated the
  MODULE_STANDARD idempotency contract despite declaring SEED_VERSION. It now
  stamps the version idempotently, mirroring the other modules.

Tests: malware stamping, stamping idempotency, and seed-loop isolation
(a failing module's partial row is rolled back and the healthy module that
follows still seeds).

Subject: [PATCH 090/281] perf(contracts): batch upsert_many and bound
 observation reads (#61)

Two payload-hygiene defects:

- PersistContract.upsert_many looped one PersistContract.upsert per record, so a
  200-record import was 200 round-trips. It now issues one
  INSERT ... VALUES ((...), ...) ON CONFLICT DO UPDATE per 500-record chunk;
  the SET clause references the excluded (proposed) row so each conflicting row
  takes its own incoming values. Heterogeneous record lists raise TypeError. The
  single-record upsert switches session.exec -> session.execute (exec is
  SQLModel's typed Select shim; execute accepts arbitrary DML), removing the
  call-overload type-ignore.
- ObservationStoreService.list_for_target fetched every row for a target with no
  ORDER BY or LIMIT, so a target with tens of thousands of observations could
  stream its whole history into a prompt build. It now caps at limit (1..500,
  default 200), returns newest-first, and accepts cursor_created_at for keyset
  paging over the existing created_at index.

Tests: upsert_many insert/conflict-update/heterogeneous-reject; list_for_target
bound, newest-first ordering, cursor paging, and limit validation.

Subject: [PATCH 091/281] fix(platform): resolve two remaining
 discarded-coroutine config reads (#65)

Two sync callers still read config through the async ConfigRegistry.get and
guarded the returned coroutine with hasattr(__await__), which always discarded
the value:

- TaskQueue._get_redis_url dropped a DB-configured redis_url, so enqueue fell
  back to env-only resolution and reported the worker unreachable whenever the
  URL lived only in config.
- ReasoningService._load_profile_override silently ignored an operator's
  per-domain reasoning profile override, always using the hardcoded fallback.

Both now use the sync read path ConfigRegistry.get_sync (C3). Test doubles in
test_task_queue align to get_sync; TestGetRedisUrl covers configured/empty/
unconfigured/raising cases.

Subject: [PATCH 092/281] fix(platform): make periodic-sweep re-registration
 idempotent (#46)

register_periodic_sweep raised ValueError whenever a name was already present,
so a module __init__ imported twice in one process (test fixtures, two import
paths for the same module) crashed import-time registration. Registering the
same callable under the same name is now a no-op; only a DIFFERENT callable
under an in-use name raises, which is the genuine name-collision bug the check
is meant to catch.

Subject: [PATCH 093/281] fix(audit): commit audit rows in the business
 transaction; fail loud on drop (#52)

Three handlers wrote their audit row in a second transaction after the business
change had already committed, so a crash between the two commits lost the audit
trail. revoke_api_key, update_system, delete_system, and _add_user_msg now
record the audit event before a single commit, inside the same session (the
atomic conditional UPDATE in revoke_api_key is preserved). An audit-write
failure now rolls the business change back with it.

The emitter's _audit_db destination re-raises instead of swallowing at debug, so
the existing _dispatch guard logs at ERROR and increments the audit_db
destination-failure counter -- a dropped audit row is now visible.

SystemService gained an optional emitter and emits system registered/deregistered
events on register/deregister; the no-emitter path stays a no-op (backward
compatible with existing constructors).

Additional commit/audit/commit sites (auth login/refresh/create_api_key,
systems create_system, sessions _sync_message) share the anti-pattern but were
outside this change's enumerated sites; left for follow-up, not masked.

Test: audit row and business row share one transaction; an audit-write failure
rolls the business row back.

Subject: [PATCH 094/281] feat(llm): budget hard-stop, pre-call budget check,
 async embedding offload (#38, #64)

- #38-3.3: check_monthly_budget now raises BudgetExceededError once month-to-date
  spend reaches 100% of the configured ceiling (hard stop, D-08). The 80% alert-
  only path is preserved for spend between 80% and 100%; the raise is emitted
  outside the infra-exception guard so it is never swallowed. No ceiling
  configured stays non-raising.
- #38-3.2: _inner_call performs a pre-flight budget check before dispatching to
  the provider, mirroring _call_with_retry, so over-budget consensus/verify
  retries refuse instead of spending.
- #64-3.1b: BGEProvider and MiniLMProvider gain encode_async, offloading the
  CPU-bound model.encode through run_blocking_io; the EmbeddingProvider Protocol
  declares it. Sync encode is unchanged.

Known consequence (not masked): the first call that pushes spend past 100%
records its cost and then raises post-hoc from persist_cost_record
(BudgetExceededError is outside cost.py's telemetry catch tuple), so that
completed response is aborted; subsequent calls are refused pre-flight. Moving
the check fully pre-flight and dropping the post-hoc raise lives in cost.py and
is out of this change's scope.

Tests: hard-stop at 101%/100%/81%/no-ceiling; _inner_call over/under/none
budget short-circuit; encode_async shape parity and thread-offload for both
providers.

+"""Async companion for the sync ``.encode`` methods on the embedding

+
+Both :class:`BGEProvider` and :class:`MiniLMProvider` gained an
+:meth:`encode_async` that offloads the CPU-bound ``model.encode(...)``
+call to a platform-owned worker thread via ``run_blocking_io`` so async
+callers never stall the event loop. These tests verify:
+
+* ``encode_async`` is a coroutine function on the Protocol AND both
+  concrete providers.
+* The returned vector has the SAME shape (list length + element type) as
+  the corresponding sync ``encode`` call for a fixed text.
+* Execution genuinely offloads: the underlying ``model.encode`` call runs
+  on a thread OTHER than the running event loop's thread. This is the
+  observable proof that ``run_blocking_io`` is doing its job.
+
+The sentence-transformers model is heavy to load, so the tests inject a
+tiny fake ``_model`` on the provider instance (the private
+``_ensure_model`` path is unchanged and still tested implicitly by the
+sync path in production).

Subject: [PATCH 095/281] perf(vuln): SQL pagination and workflow-transition
 validation on findings (#55)

- 55-3.5: get_findings_facets and list_findings pushed ordering, counting, and
  paging into SQL. Facets come from five GROUP BY queries instead of loading
  every filtered row into memory; list_findings runs one COUNT and one
  LIMIT/OFFSET SELECT with a CRITICALITY_KEYS CASE order (KEV tie-break on
  severity sort) plus a stable id-ASC tie-breaker so pages do not shuffle. The
  FindingsListResponse envelope is unchanged. Queries run through the platform
  UnitOfWork (not a raw session import).
- 55-3.8: bulk_update_findings validates every requested workflow transition
  against an explicit _ALLOWED_WORKFLOW_TRANSITIONS graph (states from the
  current_workflow_state CHECK constraint) in a preflight SELECT before the
  UPDATE; an invalid transition rolls back and returns 422 with the offending
  finding_id/current_state/target_state. The audit event carries the transition
  deltas. The design's `reason`/`poc_transcript_id` request-schema fields live
  in api/schemas/findings.py and are deferred (breaking API change coordinated
  with the frontend, and the AppendJournal tie-in is blocked on #52).

Tests: bounded severity-ordered page, disjoint offset page, invalid transition
rejected, valid transition applied, transition graph covers every declared
state, CRITICALITY_KEYS pinned.

Subject: [PATCH 096/281] feat(forensics): list pagination and freeflow cost
 ceiling (#59)

- 59-3.4: list_evidence, list_findings, and list_investigations gained
  page/page_size query params (page_size 1..500, default 100), a stable
  created_at DESC, id ASC ordering, and SQL-level LIMIT/OFFSET. list_findings
  paginates at the ArtifactRecord layer where the row count blows up. The
  DataEnvelope[list[X]] response shape and existing project-ownership scoping
  are preserved.
- 59-3.6: ForensicsConfigSchema gained freeflow_max_cost_usd (default 25.0). The
  freeflow state spawns a cost monitor beside the agent run; when month-to-date
  run cost crosses the ceiling it flips the investigation through the existing
  cancel path (same halt HonestInvestigator already polls) and overrides the
  final status to EXHAUSTED. A finally block always stops and awaits the monitor.

Known limitation (not masked): the cost query sums LLMCostRecord by
run_id == investigation_id, but the reasoning engine does not yet thread the
investigation run_id into its LLM calls, so LLMCostRecord.run_id is empty for
freeflow calls and the ceiling stays inert in production until that upstream
run_id plumbing lands. The mechanism, config field, and termination path are
correct and unit-tested with seeded cost rows.

Tests: bounded pages for all three list endpoints (with disjoint-offset proof),
the pure ceiling predicate, the config field, the cost-sum query with
cross-investigation isolation, and an end-to-end monitor cancel.

+"""#59 findings 59-3.4 (list pagination) and 59-3.6 (freeflow cost ceiling).
+
+Two disjoint acceptance surfaces, both grounded on the source paths named

+
+* ``list_evidence`` / ``list_findings`` / ``list_investigations`` in
+  ``src/aila/modules/forensics/api_router.py`` previously fetched every
+  matching row before any Python-side slicing. LIMIT/OFFSET at the SQL
+  layer now caps each response to ``page_size`` items.
+* ``ForensicsConfigSchema.freeflow_max_cost_usd`` is a new operator knob;
+  the enforcement helpers in
+  ``src/aila/modules/forensics/workflow/states/freeflow.py`` sum
+  ``LLMCostRecord.cost_usd`` per ``run_id == investigation_id`` and the
+  monitor loop flips the investigation to ``cancelled`` (which the
+  investigator turn-loop already halts on) when the cap is crossed.
+
+Tests here exercise both the endpoint-level page bound AND the pure
+ceiling-check helper wired against real ``aila_test`` rows.

Subject: [PATCH 097/281] fix(forensics): surface non-zero script exit instead
 of reporting success (#58)

ScriptExecutorTool.forward ran the remote extraction script via ssh.run_command
and unconditionally reported exit_code=0 on success, so a script that failed
with a non-zero exit was recorded as valid evidence. Added
SSHService.run_command_full, which returns (stdout, stderr, exit_code) rather
than raising UpstreamError on non-zero exit, mirroring run_command for idle
timeout, exit-status grace, host-key policy, and stderr redaction (C6). forward
now returns the real exit code, and connection-level failures (authentication,
host-key mismatch, transport, idle timeout) propagate to the caller instead of
being flattened to exit_code=1, so file_retriever's exit_code != 0 guard finally
enforces the script contract. Script cleanup still runs in a finally block, with
its swallowed-exception set widened so a cleanup error cannot mask the real one.

Test: a non-zero exit is surfaced (not hard-coded 0), a clean exit still
succeeds, and an authentication error propagates while cleanup still runs.

+"""Tests for finding 58-3 (`.run/designs/DESIGN_injection_evidence.md` §3.3).
+
+Contract change
+---------------
+``ScriptExecutorTool.forward`` used to call ``SSHService.run_command`` and
+hard-code ``exit_code=0`` on the success branch, mapping every raised
+exception to ``exit_code=1`` with a generic string. A remote script that
+ran and called ``sys.exit(3)`` produced ``UpstreamError`` from
+``run_command`` (its raise-on-nonzero contract), which was NOT in the
+tool's ``except`` tuple ``(OSError, TimeoutError, ConnectionError,
+RuntimeError)`` -- so the ``UpstreamError`` propagated uncaught and the
+caller (``file_retriever._run_script_and_pull``) never saw an honest
+``exit_code``. Meanwhile a successful exec returned ``exit_code=0`` no
+matter what the remote actually exited with, because the return dict
+was a hard-coded ``0``.
+
+The rewrite switches to ``SSHService.run_command_full`` -- a new
+platform method that returns the ``(stdout, stderr, exit_code)``
+triple without converting non-zero exit into an error, and still
+raises ``AuthenticationError`` / ``UpstreamError`` / platform
+``TimeoutError`` for connection-level failures (those mean "the
+script never ran"). These tests lock the new behaviour so a future
+edit cannot silently regress to the old exit-code-lies-on-nonzero
+shape.
+
+Mocking strategy
+----------------
+The SSH layer is mocked with :class:`unittest.mock.AsyncMock` on the
+``ScriptExecutorTool`` module's deferred import of ``get_ssh_service``
+so no live host is required. ``analyzer_os="linux"`` is used so the
+Windows-only ``echo %TEMP%`` probe (which would need a separate
+``run_command`` stub) is not exercised -- the exit-code contract is
+OS-agnostic.

Subject: [PATCH 098/281] fix(llm): fence untrusted tool output and report
 facts against prompt injection (#43)

Untrusted content reached the model as if it were trusted instruction text:
- _tool_loop appended raw tool/MCP results directly to the message list, so a
  tool return could carry instructions into the agent prompt.
- vr writer_agent._render_facts embedded raw investigation facts into the
  report-writer prompt.

New platform/llm/untrusted.py sanitize_untrusted(text, *, source) fence-wraps
content in a labeled <untrusted-input> delimiter and mangles any embedded fence
sentinel so injected content cannot close the fence early; the source label is
scrubbed and length-capped so a hostile source string cannot break out of the
opening tag. _tool_loop now fences each executor tool result (keyed by tool
name); the platform-authored timeout JSON stays unfenced so telemetry parsing is
unchanged. writer_agent runs every embedded fact through sanitize_input, wraps
the whole facts block in one data fence, keeps the schema instruction outside
the fence, and gains a system-prompt trust-boundary section teaching the model
to treat fenced content as evidence only.

Tests: fence wrapping, verbatim payload preservation, begin/end sentinel escape,
source-attribute injection escape, idempotent double-wrap, and _tool_loop
fencing a tool result while the synthesized timeout result stays parseable.

+"""Fence-wrap third-party bytes before they reach an LLM prompt.
+
+Companion to :mod:`aila.platform.llm.sanitize`. Where ``sanitize_input``
+strips known injection patterns (D-01 through D-05), this module marks
+the boundary between platform-authored instructions and untrusted data
+that flowed in from an MCP bridge, HTTP fetch, SSH command, or a
+persisted third-party field. The two defences compose -- callers who
+want both call ``sanitize_input`` first, then ``sanitize_untrusted``.
+
+Design reference: ``.run/designs/DESIGN_injection_evidence.md`` issue
+#43 finding 43-1. The tool-loop at ``client.py:_tool_loop`` appended
+tool results raw, so untrusted output could inject fresh instructions
+into the next model turn. Wrapping with a constant literal fence gives
+the model a clear signal to treat the payload as quoted data, and
+escaping any occurrence of the fence sentinel inside the payload
+guarantees the third-party bytes cannot close the outer fence early.
+
+The wrapper preserves content verbatim -- it does not strip, truncate,
+normalise, or otherwise mutate the payload semantics. Any character
+budgeting or pattern stripping is a caller decision made before this
+helper runs.

Subject: [PATCH 099/281] fix(audit): commit remaining audit rows in the
 business transaction (#52)

Extends the audit-in-transaction fix to the three sites left as follow-ups:
create_api_key, create_system, and _sync_message (assistant path) each wrote
their audit row in a second transaction after the business change committed.
Each now records the audit event before a single commit in the same session:
create_api_key reads the default_factory-populated id/created_at pre-commit;
create_system flushes to populate the DB-generated PK (the unique-name
IntegrityError still short-circuits to 409 before any audit staging);
_sync_message flushes to populate the assistant message PK referenced in the
audit details. An audit-write failure now rolls the business change back.

Test: create_api_key audit row and business row share one transaction, and an
audit-write failure rolls the key row back.

 Proves the audit row and the business change share the same
-transaction at the systems.py delete_system site. Two scenarios:
+transaction at each site that used to split them across two commits.
+Two scenarios per site:
 
-1. Happy path -- after DELETE /systems/{id} both the business row is
-   gone AND an AuditEventRecord row exists. Post-#52-3.2 both writes
-   commit in a single transaction.
+1. Happy path -- after the request handler runs, the business row
+   is in its post-change state AND an AuditEventRecord row exists.
+   Post-#52-3.2 both writes commit in a single transaction.
 2. Failure path -- patch record_audit_event in the router module to
-   raise BEFORE the commit; the pre-staged session.delete MUST roll
-   back with it. The pre-fix flow committed the delete first and the
-   audit row second, so this rollback was impossible; the test now
-   guards against regression to that split.
-
-The systems delete site was picked for the acceptance test because
-it is the shortest handler with an in-scope audit-after-commit
-finding, and its 204-No-Content contract makes the row-present /
-row-absent assertions unambiguous.

+Sites covered:
+  * ``systems.delete_system`` -- shortest handler with an in-scope
+    finding; its 204-No-Content contract makes row-present /

+  * ``auth.create_api_key`` -- extends coverage to the follow-up

+    (uuid default_factory) so the audit payload can reference it
+    before commit -- no flush needed there, unlike the sequence-PK
+    ManagedSystemRecord path in ``create_system``.

Subject: [PATCH 100/281] fix(sse): lifetime cap, disconnect detection, and
 active-connection gauge (#60)

- 60-3: ProgressStream.stream_events had an unbounded while loop, so a well-
  behaved client with an open EventSource pinned a Redis pool connection
  forever. It now ends cleanly once MAX_STREAM_LIFETIME_S (300s, mirroring
  sse_events.MAX_CONNECTION_S) elapses; the client EventSource auto-reconnects.
- 60-4: stream_task_events and stream_scan_events never checked
  request.is_disconnected(), so a zombie client held a coroutine and a Redis
  connection until the next XREAD tick (up to 30s). Both now take the Request,
  check is_disconnected() each live-loop iteration, and end promptly.
- 60-6: the ACTIVE_SSE gauge was defined but never touched. It is now
  incremented when an SSE generator starts and decremented in a finally on
  every exit path (normal end, disconnect, exception) across the sse_events,
  tasks, and scans SSE handlers.

Tests: lifetime cap ends the generator after the deadline; a disconnected
client ends the scan/task stream on the first check; the gauge increments then
decrements in order.

+"""Focused tests for SSE hardening (Phase 60 findings 60-3, 60-4, 60-6).

+Covers three narrow behaviors introduced by the hardening slice:
+
+  60-3: ``ProgressStream.stream_events`` has a bounded lifetime cap so a
+        well-behaved client cannot pin a Redis pool connection forever.
+  60-4: ``stream_task_events`` and ``stream_scan_events`` check

+        the generator promptly instead of looping until the next XREAD
+        tick (up to 30 s) with a zombie client.
+  60-6: ``ACTIVE_SSE`` gauge is incremented when an SSE generator starts
+        and decremented in a ``finally`` when it ends, on every exit path.
+
+All tests use mocked Redis (patched ``ProgressStream``) and a mocked
+``Request.is_disconnected``; no live Redis, no live infrastructure.
+Follows the proven SSE-test mock pattern in
+``tests/api/test_96_sse_streaming_verification.py``.

Subject: [PATCH 101/281] fix(automation): overlap guard, claim-before-submit
 ordering, per-schedule isolation, registry lock (#46)

- 46-3: AutomationRunner.tick() gained an asyncio.Lock so a slow tick that
  overlaps the next cron fire is skipped instead of double-submitting. The
  per-schedule path now writes last_run_at + last_run_result='pending' BEFORE
  the queue submit (rewritten to 'submitted:<task_id>' on success, 'error' on
  failure), so a crash between claim and submit marks the schedule fired for the
  cycle rather than letting the next tick re-fire it.
- 46-4: the per-schedule loop caught only (AILAError, SQLAlchemyError), so a
  handler raising anything else aborted the whole tick and starved later
  schedules. It now isolates each schedule with the same resilience-boundary
  exception set the emitter uses, logs with traceback, and continues;
  KeyboardInterrupt/SystemExit/CancelledError still propagate.
- 46-8: AutomationRegistry claimed thread-safety without a lock. A threading.Lock
  now guards register_action (the check-then-set race) and list_actions (dict
  iteration during mutation).

Tests: overlap skip, claim-before-submit ordering (success and submit-failure
paths), per-schedule exception isolation, atomic registration under 24-thread
contention, and stable list snapshot under concurrent writes.

+Covers findings from `.run/designs/DESIGN_automation_events_reporting.md` #46:
+
+- 46-3 overlap guard: concurrent tick() invocations serialize; the second
+  returns 0 without touching the database.
+- 46-3 ordering: last_run_at is claimed BEFORE the queue submit, so a
+  submit failure marks the schedule as fired (with result "error") for
+  this cron cycle instead of letting the next tick re-fire the same row.
+- 46-4 per-schedule isolation: a handler / submit path that raises
+  RuntimeError (or any other member of the broadened isolation tuple)
+  does not stop later schedules in the same tick from being processed.
+- 46-8 registry thread-safety: register_action is atomic under concurrent
+  callers, and list_actions returns a stable snapshot even when
+  register_action is running in parallel.

Subject: [PATCH 102/281] fix(malware): gate playbook step dispatch behind a
 tool allowlist (#58)

PlaybookRunnerService._run_step dispatched whatever MCP tool a proposed playbook
named, with no allowlist, so an auto-proposed or poisoned playbook could invoke
any wired MCP tool. New playbook_allowlist.py declares the read-only tool ids a
playbook step may invoke (audit_mcp and ida_headless_exp read tools) as a static
frozenset with an exact-match is_allowed(). _run_step now rejects a step whose
tool is not on the allowlist before touching the dispatch path, returning a
failed step result (tool_not_allowlisted) so the playbook's on-failure policy
still applies.

Follow-ups (not in scope, no DDL): per-workspace allowlist extras via
ConfigRegistry once the runner carries a registry/workspace_id, create/update-
time enforcement in the playbook API handlers, and a journal denial event once
the AppendJournal wiring (#52) reaches this service.

Test: an allowlisted tool dispatches; a non-allowlisted tool is rejected before
_mcp_dispatch is awaited; exact-match semantics (no prefix/substring/case-fold).

+"""Playbook MCP-tool allowlist -- issue #58 finding 58-1.
+
+A malware playbook is an ordered list of MCP tool calls executed by
+``PlaybookRunnerService`` against a target. A playbook row lives in
+``MalwarePlaybookRecord.steps_json`` and the ``tool`` field on each
+step accepts any 1--128 char string (see
+``modules/malware/contracts/playbook.py:MalwarePlaybookStep``).
+
+Without an allowlist any operator who can write that row -- or the
+post-completion ``PlaybookProposer`` that writes
+``status='proposed'`` rows over untrusted case content -- can name
+any MCP function the runner's ``mcp_dispatch`` callable can reach.
+That is the finding 58-1 primitive: playbook-driven arbitrary
+tool invocation.
+
+The gate here is the runtime allowlist. Read paths under audit_mcp
+and ida_headless_exp are the only tools a playbook is ever allowed
+to dispatch. The set is deliberately narrow: adding a new tool is a
+PR-reviewed change to this module. There is NO substring match, NO
+prefix match, and NO wildcard support -- exact equality only.
+
+Design reference: ``.run/designs/DESIGN_injection_evidence.md`` §3.1
+under "Issue #58 -- untrusted execution and evidence".
+
+Follow-up (out of this slice):
+- Create/update-time enforcement in the ``POST /malware/playbooks``
+  and ``PATCH /malware/playbooks/{id}`` handlers so a poisoned row
+  fails at write time as well as at dispatch time.
+- Per-workspace config-driven extras via ``ConfigRegistry`` key
+  ``malware.playbook_tool_allowlist_extra_<workspace_id>`` (design
+  §3.1 ``resolve_allowlist``). Requires threading ``registry`` +
+  ``workspace_id`` into ``PlaybookRunnerService``; not wired here.
+- AppendJournal (C2, tracked in issue #52) audit event
+  ``playbook_step_denied`` on each rejection. Currently logged.

Subject: [PATCH 103/281] fix(forensics): re-hash pulled evidence locally
 instead of trusting the analyzer (#58)

_run_script_and_pull returned header['sha256'] -- the hash the untrusted
analyzer host REPORTED -- as the authoritative digest, so a compromised or buggy
analyzer could report a value that did not match the bytes actually delivered.
New hash_ledger.py computes and verifies sha256 over local bytes
(verify_or_raise / verify_file_or_raise, streamed 1 MB chunks, claim-shape
validated as 64-char hex before comparison). _run_script_and_pull now recomputes
the digest over the pulled file through the platform run_blocking_io offload and
returns the local digest on match; on mismatch it quarantines (unlinks) the
local copy and raises FileRetrievalError, logging claimed vs computed for the
operator run log.

Follow-ups (not in scope, depend on #52 AppendJournal DDL): emit
retrieval_hash_reported / retrieval_hash_verified journal events, and a
honesty-audit rule flagging a retrieval helper that returns header['sha256']
without an intervening verify call.

Test: matching bytes return the locally recomputed hash; a mismatch raises with
claimed/computed/size populated; garbled claim raises ValueError before opening
the file; streamed multi-chunk compute matches hashlib.

+"""Local hash re-verification helpers (finding 58-2).
+
+Reusable SHA-256 compute + verify helpers used by the forensics
+retrieval path (``file_retriever._run_script_and_pull``) to
+recompute the hash of file bytes pulled from an analyzer over
+SSH/SFTP and compare it to the value the analyzer-side extraction
+script reported in its ``##AILA-RETRIEVE##`` header.
+
+Threat model
+------------
+The forensics threat model treats the analyzer host as untrusted
+(see the ``file_retriever`` module docstring). Returning the
+header-supplied ``sha256`` verbatim lets a compromised or buggy
+analyzer report a value that does not match the bytes actually
+delivered -- either to hide tampering, to evade deduplication, or
+to plant a chain-of-custody signature that a later auditor cannot
+reproduce.
+
+Contract
+--------
+``verify_or_raise(local_bytes, claimed_sha256)`` recomputes the
+SHA-256 over the pulled bytes and returns the locally-computed
+hex digest when it matches; on mismatch it raises
+:class:`HashMismatchError`. ``verify_file_or_raise(local_path,
+claimed_sha256)`` performs the same check with a streamed 1 MB
+chunk read so a multi-GB acquisition does not need to sit in
+memory. Neither helper touches the DB or the network -- they are
+pure compute over bytes / a local file.
+
+Follow-up (not shipped here)
+----------------------------
+Design section 3.2 proposes an AppendJournal ``retrieval_hash_verified``
+event so an auditor can prove after the fact which retrievals were
+verified and which mismatched. That path depends on issue #52
+(AppendJournal DDL). See ``.run/designs/DESIGN_injection_evidence.md``
+issue #58 finding 58-2 for the full write-up. Migration is out of
+scope for this module; the compute + fail-closed core lives here
+and the caller (``file_retriever``) already emits a WARN log on
+mismatch which the operator's run log captures.

+``file_retriever._run_script_and_pull`` used to trust the ``sha256``
+value the analyzer-side extraction script reported in its
+``##AILA-RETRIEVE##`` header and return it as the authoritative hash
+of the pulled file. The forensics threat model treats the analyzer

+
+The fix moves the compute + compare into a reusable
+:mod:`aila.modules.forensics.services.hash_ledger` module:
+
+* ``verify_or_raise(local_bytes, claimed_sha256)`` recomputes the
+  SHA-256 over the pulled bytes and returns the locally-computed

+* On mismatch it raises :class:`HashMismatchError` carrying both the

+* A malformed ``claimed_sha256`` (wrong length or non-hex) raises
+  ``ValueError`` at the boundary so a garbled claim is not

+
+These tests exercise the compute + verify core directly with byte /

+
+Companion caller-side change
+----------------------------
+``file_retriever._run_script_and_pull`` calls
+:func:`verify_file_or_raise` in a worker thread after the SFTP pull,
+quarantines the local copy on mismatch, wraps the exception in
+``FileRetrievalError`` for a caller-facing message, and returns the
+locally-recomputed digest thereafter. That composition is covered by
+the existing forensics retrieval integration path; the isolated
+compute contract lives here.

Subject: [PATCH 104/281] fix(vuln): harden the synchronous PDF render env
 against injection (#43)

The async render path was hardened earlier, but PDFReportRenderer.render (the
synchronous path) still built a bare Jinja2 Environment with no autoescape and
no safe_url filter, then rendered the same template that emits
{{ row.nvd_url | safe_url }} and untrusted finding/note fields. HTML in a host,
package, note, or rationale survived into the PDF and a javascript:/data: nvd_url
reached the href. render now uses the shared _build_report_env (autoescape +
safe_url), matching the async path; the now-unused jinja2 Environment/Undefined
import is dropped.

Test: rendering the real _HTML_TEMPLATE through _build_report_env escapes a
script/img note and system_name and neutralizes a javascript: nvd_url to
about:blank.

Subject: [PATCH 105/281] fix(forensics): run deep-analysis SSH off the DB
 connection (#63)

state_deep_analysis ran _analyze_single_file (strings/FLOSS/capa over SSH, seconds
per file) inside an open UnitOfWork, so a pooled DB connection was held for the
entire multi-file pass -- a pool-exhaustion risk under concurrent investigations.
Split into two phases: _collect_deep_artifacts runs all SSH analysis with no
session open and returns (artifact, source_evidence_id) pairs; _persist_deep_artifacts
adds them in one short transaction. Behavior is preserved -- a file whose analysis
raises is still logged and skipped, and the artifact set, counts, and return
payload are unchanged.

Tests: collection skips a failed file and pairs the source id; persistence writes
every collected artifact with correct per-family counts.

Subject: [PATCH 106/281] fix(forensics): enqueue readiness analysis outside
 the DB session (#63)

check_readiness flipped the project CREATED->READY and then called
task_queue.submit (an ARQ/Redis network await) while the UnitOfWork was still
open, pinning the pooled DB connection across the enqueue. The status flip is
already committed inside the session; the submit now runs after the session
closes, guarded by an enqueue_mode sentinel so it fires only when the flip
happened. Behavior is unchanged: same status transition, same task, same
kwargs.

Test: a ready machine flips the project to READY and enqueues the analysis task
with the project id; a not-ready machine leaves it CREATED and enqueues nothing.

Subject: [PATCH 107/281] perf(events): reuse a pooled sync Redis client in the
 emitter (#60)

The redis_stream destination opened redis.from_url and closed the connection on
every emitted event, so a run emitting hundreds of stage events paid hundreds of
TCP connect/teardown cycles. A redis-py client owns a thread-safe internal
connection pool, so the emitter now caches one client per URL
(_get_sync_redis_client) and reuses it across events and drains; the per-event
close is removed. The RedisError -> RuntimeError escalation into the drain
isolation guard is unchanged.

Test: _get_sync_redis_client creates the client once per URL and returns the
same instance on subsequent calls.

Subject: [PATCH 108/281] fix(forensics): guard markdown link scheme in
 WriteUpViewer (#43)

The inline markdown renderer inserted a link target straight into an href. The
upstream HTML-escape only handles &, <, and >, so an untrusted writeup link
could carry a javascript:/data:/vbscript: scheme that runs on click, or a quote
that breaks out of the href attribute into a new event-handler attribute. A
safeHref guard now collapses whitespace and control characters (browsers strip
these before resolving a scheme) to detect the real scheme, rejects anything
outside http/https/mailto to about:blank (relative and anchor links pass), and
escapes quotes. The link replacer uses a function form so the target flows
through safeHref instead of a raw $2 substitution.

Verified: javascript:/data:/vbscript:, case-variant, control-char-split, and
leading-whitespace schemes resolve to about:blank; https/mailto/relative/anchor
links are preserved; a quote-breakout payload is escaped. Full workspace
type-check clean.

Subject: [PATCH 109/281] refactor(platform): drop dead notification_types and
 cost is_admin branch (#41, #57)

- #41-3d: ModuleProtocol.notification_types() had no callers and no module
  overrides anywhere in the tree; removed the dead stub.
- #57-3f: estimate_scan_cost gated a branch on getattr(auth, "is_admin", False),
  but AuthContext has no is_admin attribute (that lives on TeamContext), so the
  guard was always False and the 403 already fired unconditionally. Removed the
  always-true wrapper. This also exposed the branch's post-raise block as
  unreachable dead code -- and it was an unscoped cross-tenant cost query (no
  team_id filter) that the buggy guard had been silently shielding. Removed it:
  a team-less principal now cannot run a cross-tenant cost aggregation, matching
  the multi-tenant isolation contract.

Test: /cost/estimate with a team-less admin token returns 403.

Subject: [PATCH 110/281] fix(api): OIDC cookie secure flag and CORS credential
 hardening (#36)

- 3c item 1: the oidc_state cookie was set with secure=False. Added
  Settings.oidc_cookie_secure (env AILA_OIDC_COOKIE_SECURE, default True) and
  drive the set_cookie secure flag from it, so the state cookie is sent only
  over HTTPS by default.
- 3c item 4: CORSMiddleware was configured with allow_credentials=True
  regardless of the origin allowlist. Credentials combined with a wildcard
  origin is unsafe; _cors_allow_credentials now disables credentials whenever
  the resolved origin list is or contains "*", and keeps them enabled for a
  concrete allowlist.

Deferred (out of this pure-code slice): item 2 (first-login role -> an
OIDCProviderRecord column, needs a migration) and item 3 (refresh_token
Query -> Body, a breaking API change coordinated with the frontend).

Tests: cookie secure defaults True and follows the setting; CORS credentials
disabled for wildcard/mixed origins, enabled for a concrete allowlist; Settings
field-set assertions updated for the new field.

Subject: [PATCH 111/281] fix(http): redact secrets from surfaced httpx errors
 (#42)

HTTPFetchTool.forward let httpx.HTTPError propagate raw: the exception string can
echo the request URL (query-string tokens) or an Authorization header value, so
a token could leak into logs and the agent-visible error. The request loop and
raise_for_status are now wrapped; an httpx.HTTPError is re-raised as a ValueError
whose message passes through redact_secrets (Bearer, token=, sk- keys). Policy
errors (SSRFBlockedError, the no-response ValueError) are raised inside the try
but are not httpx.HTTPError, so they propagate unredacted as before.

Tests: a Bearer token and a query-string token in an httpx.ConnectError message
are both redacted to [REDACTED] in the surfaced error, with the upstream-error
framing preserved.

Subject: [PATCH 112/281] fix(vr): treat a null outcome timestamp as
 never-fresh in section cache (#48)

is_cache_fresh returned True when outcome_updated_at was None, so a report
section cached against an outcome row with a null updated_at was served as fresh
forever. A null updated_at signals an under-populated row, not freshness; it now
returns False so the section regenerates instead of serving a stale cache.

Test: null outcome timestamp is not fresh; newer cache is fresh; older cache is
stale; missing/empty/unparseable cache entries are not fresh.

Subject: [PATCH 113/281] feat(malware): dedup observation writes via partial
 unique index (#61)

record_observation could insert an identical fact (same target + kind + payload)
repeatedly, bloating the store and, once wired into prompt build, the context.
Added malware_observations.dedup_hash (sha256 of target|kind|canonical payload)
and a partial unique index ux_malware_observations_dedup on
(target_id, kind, dedup_hash) WHERE dedup_hash IS NOT NULL AND
superseded_by_id IS NULL. record_observation now inserts via ON CONFLICT DO
NOTHING against that index: a live duplicate is a no-op that returns the existing
row id and skips the supersede + cross-target propagation work, so recording the
same fact is idempotent. Distinct payloads and re-observing after a supersession
(the superseded row leaves the partial index) still insert.

Migration 072 adds the column and partial index; the partial predicate excludes
rows that predate the column (NULL hash), so it builds cleanly on existing data
with no dedupe-before-index step.

Tests: identical record returns the same id and leaves one row; distinct payloads
create two rows.

Subject: [PATCH 114/281] fix(api): await async platform handle in session chat
 endpoint

POST /sessions/{id}/messages called the async AILAPlatform.handle
without awaiting it, so both the JSON and SSE paths discarded the
returned coroutine and the reply fell back to echoing the user's own
text. The streaming path additionally bridged the async handle through
a worker thread with a token_callback kwarg the handle never accepts.

Both paths now await handle() directly in the request event loop. The
non-streaming path runs it outside the DB session so no pooled
connection is held across the run, then writes the assistant message
and its audit row in one transaction. The streaming path emits the
resolved summary as a single token event followed by a done event that
carries the run_id.

Aligned the session chat tests to the async handle contract: the stub
platforms now expose an awaitable handle and the token-streaming
assertion expects the summary as one token event.

Subject: [PATCH 115/281] chore(release): 0.3.0 -- security, correctness, and
 reliability hardening

Bump every version site (pyproject, root and workspace package.json,
typescript-config, the five module frontends, fuzz reporter) to 0.3.0
and add the 0.3.0 CHANGELOG entry. The lockfile is unchanged: workspace
package versions are not recorded under the workspace protocol.

The entry covers the authentication, tenant-isolation, secret-handling,
LLM cost and resilience, audit-integrity, and per-module correctness
work landed since 0.2.1, plus the PostgreSQL test-suite migration.

Behavior change requiring possible caller action: CORS credentials are
disabled under wildcard origins, and the OIDC state cookie is marked
secure by default. The list endpoints are not breaking; the vulnerability
findings response envelope is unchanged and forensics list responses stay
a DataEnvelope list.

+## [0.3.0] - 2026-07-20 -- Security, correctness, and reliability hardening
+
+A broad hardening pass across authentication and tenant isolation,
+secret handling, LLM cost and resilience, audit integrity, and
+per-module correctness, plus a migration of the test suite onto
+PostgreSQL. Read the Changed section first: the CORS and OIDC
+credential defaults changed and may require caller action.
+
+### Added
+
+- Append-only, hash-chained platform journal for tamper-evident audit;
+  the CLI audit trail now writes to it. (C2)
+- Evidence packs sealed with a merkle digest so later tampering is
+  detectable.
+- Per-run LLM token budget with a hard stop and a pre-call check;
+  embedding computation offloaded off the event loop. (#38, #64)
+- Team-scope request resolver and an `owned_or_404` helper for
+  single-resource authorization. (C1, #36, #57)
+- Secret redaction at the log boundary and for non-admin config reads.
+  (C6, #50)
+- Optional `page` and `page_size` params on the forensics list
+  endpoints (evidence, findings, investigations); the response stays a
+  `DataEnvelope` list. (#59)
+- Workflow-transition validation on findings bulk-update: an off-graph
+  transition is now rejected with 422. (#55)
+- Per-call LLM cost ceiling and output-size bound for forensics
+  writeups. (#48)
+- Freeflow investigation cost ceiling
+  (`forensics.freeflow_max_cost_usd`, default 25.0) with a monitor that
+  cancels a run once its cost crosses the ceiling. Known limitation: it
+  is inert in production until the reasoning engine threads the
+  investigation run_id into its LLM cost records; the mechanism and
+  termination path are unit-tested with seeded cost rows. (#59)
+- TLS hardening for report email: admin CA bundle, implicit TLS, and
+  certificate verification. (#48)
+- `ConfigRegistry.get_sync` for synchronous call sites. (C3)
+- Eval metric functions: expected calibration error, precision,
+  recall, determinism, faithfulness. (C7)
+- Deduplication of malware observation writes via a partial unique
+  index. (#61)
+- Per-tool-execution LLM timeout and pooled AsyncOpenAI clients that
+  stop a per-call file-descriptor leak. (#44)
+
+### Changed
+
+- The vulnerability findings list pushes its pagination, ordering, and
+  count into SQL instead of slicing in Python. The response envelope
+  (`total`, `items`, `page`, `page_size`) is unchanged. (#55)
+- Behavior: CORS credentials are disabled when origins are wildcarded,
+  and OIDC cookies are marked `secure` by default. A client that relied
+  on credentials with a wildcard origin must now configure explicit
+  origins. (#36)
+- `POST /sessions/{id}/messages` awaits the platform and returns a real
+  assistant response on both the JSON and SSE paths; it previously
+  discarded the un-awaited coroutine and echoed the request text.
+- The event emitter reuses a pooled synchronous Redis client, and SSE
+  streams are bounded by a lifetime cap with disconnect detection and
+  an active-connection gauge. (#60)
+- `upsert_many` batches its writes; observation reads are bounded and
+  keyset-paginated. (#61)
+- Legacy `AILAError` subclasses map to their real HTTP status codes.
+- The test suite runs against PostgreSQL with async fixtures instead of
+  SQLite. (#62)
+
+### Fixed
+
+Security and tenant isolation:
+
+- OIDC callback validates the state against the signed cookie; every
+  callback previously failed against a nonce field the state JWT never
+  emitted. (#36)
+- IDOR closed across malware investigation, observation, and
+  subresource routes; team ownership enforced on target, systems, and
+  tags routers. (#57, #36)
+- Untrusted tool output and report facts fenced against prompt
+  injection; markdown link schemes guarded in the forensics writeup
+  viewer; vulnerability and synchronous PDF render environments
+  hardened with autoescape and URL-scheme guards. (#43)
+- SSRF policy re-validated on every redirect hop; secrets redacted from
+  surfaced httpx and provider errors. (#42, #44)
+- SFTP path traversal rejected on upload and download; playbook step
+  dispatch gated behind a tool allowlist; pulled evidence re-hashed
+  locally instead of trusting the analyzer; non-zero script exit
+  surfaced instead of reported as success. (#58)
+- Crash discovery rejects symlinks and oversized files. (#51)
+- API key revocation made atomic to close a duplicate-revoke race;
+  audit rows committed inside the business transaction and failing
+  loud on drop. (#52)
+
+LLM and cost:
+
+- `LLMResponse` declares its pipeline metadata fields (populating them
+  previously raised `TypeError`); temperature-reject markers match on
+  token boundaries; the dead health lock removed. (#44)
+- Non-retryable provider errors fail fast; cost-telemetry failures no
+  longer fail the LLM call; budget alerting never raises spuriously;
+  the per-run token budget is enforced via the sync config read. (#44,
+  #38)
+
+Modules:
+
+- Vulnerability: GHSA matches gated by version, cve TTL honored, the
+  NVD limiter moved off the event loop; criticality vocabulary and
+  fallback scoring corrected; proxy resolved via the sync read;
+  `weekly_digest` made async; `list_system_tags` returns full rows.
+  (#55)
+- Forensics: deep-analysis SSH runs off the DB connection; readiness
+  enqueue moved outside the DB session; child tables purged on project
+  delete; real `ArtifactRecord` fields read in the writeup builder.
+  (#59, #63)
+- Malware: investigation narrative sanitized on persist; deterministic
+  token-boundary family match; workspace and tag-index constraint
+  names module-prefixed to match their migrations.
+- VR: finding evidence refs schema-validated at write time; a null
+  outcome timestamp treated as never-fresh in the section cache. (#48)
+
+Platform, async, and correctness:
+
+- Blocking calls offloaded off the event loop; two discarded-coroutine
+  config reads resolved. (#64, #65)
+- Module seeding isolated per module with the malware seed version
+  stamped; each module constructed once during discovery; periodic
+  sweep re-registration made idempotent. (#45, #41, #46)
+- Automation gains an overlap guard, claim-before-submit ordering,
+  per-schedule isolation, and a registry lock. (#46)
+- `UnitOfWork` fails loud on uncommitted writes. (#63)
+- Scan SSE stream closes cleanly on a mid-stream backend error; binary
+  response content declared for file-download routes.
+- Knowledge dedup update uses the correct scalar-id subscript.
+- `RegisteredSystem` tolerates extra DB columns; observables guarded
+  against non-JSON values at construction. (#61)
+- Journal hash-length check uses a portable `length()` constraint. (C2)
+
+### Removed
+
+- Dead `notification_types` and an unreachable unscoped cross-tenant
+  cost query. (#41, #57)

Subject: [PATCH 116/281] fix(automation): supervise the tick loop with
 exponential backoff (#46)

The automation tick loop caught only (AILAError, SQLAlchemyError,
ValueError, OSError) and slept a fixed 60s. A tick raising anything
outside that set -- KeyError, RuntimeError, TypeError from a malformed
schedule row -- escaped the loop and killed the task, silently halting
all automation until the next process restart.

Extract the loop into platform/automation/supervisor.py:
run_tick_supervisor catches every realistic tick fault via a broad but
explicit tuple (mirroring the runner isolation tuple), logs it with a
traceback, counts it on the new aila_automation_tick_failures_total
metric labelled by exception class, and backs off exponentially
(60s base, 300s cap, 10% jitter) with a reset on the first success.
asyncio.CancelledError still propagates so shutdown stays prompt, and a
stop_event lets the lifespan halt the loop cleanly before cancelling.

The Redis leader-lock (design section 3.2) is deferred as a separate HA
concern. Adds tests/platform/automation/test_supervisor.py.

Subject: [PATCH 117/281] fix(config): declare SMTP scheduled-report keys in
 the platform schema (#45)

report_tasks.py reads smtp_host, smtp_port, smtp_from, smtp_username,
smtp_password, smtp_ca_bundle_path, and smtp_use_implicit_tls through
ConfigRegistry, but PlatformConfigSchema declared none of them. Because
the registry only seeds and accepts keys present in a registered schema,
the rows were never created, get() returned None, and
PUT /config/platform/smtp_* was rejected as an unknown key -- email
delivery was configurable only through env vars while the config API
presented no way to set it.

Declare the seven keys with the defaults report_tasks documents
(smtp_port 587, smtp_from aila@localhost, the rest empty/false).
smtp_password matches the is_secret_config_key "password" token, so it
is redacted for non-admin readers (C6). Adds a schema-field test class
asserting every key is declared with its default and that smtp_password
is secret-classed.

Subject: [PATCH 118/281] feat(storage): make DB connection pool sizing
 env-tunable (#45)

get_async_engine hardcoded pool_size=10, max_overflow=10,
pool_timeout=30, pool_recycle=1800, so a deployment scaling above the
default concurrency could not enlarge the pool without a code change.

Add _resolve_pool_config, which reads AILA_DB_POOL_SIZE,
AILA_DB_MAX_OVERFLOW, AILA_DB_POOL_TIMEOUT, and AILA_DB_POOL_RECYCLE and
falls back to the previous defaults on a missing or non-integer value.
Env-only (not ConfigRegistry) because the engine is built before the
registry exists on some paths. Values like max_overflow=0 and
pool_recycle=-1 pass through unchanged. Adds tests/storage/test_pool_config.py.

Subject: [PATCH 119/281] fix(tasks): correct workflow retry backoff off-by-one
 (#40)

The WorkflowConflictError retry path raised
Retry(defer=default_backoff(job_try)), but job_try is ARQ's 1-based
attempt counter. During the first attempt (job_try=1) zero retries have
completed, so the defer must be default_backoff(0) in [1.0, 2.0);
passing job_try produced default_backoff(1) in [2.0, 3.0) and every
subsequent retry was likewise one exponent too high.

Pass job_try - 1. Extends the existing conflict-to-Retry test with a
regression that patches default_backoff and asserts the first attempt
backs off on 0 completed retries. The three-source task-engine desync
and the ARQ __name__ collision remain out of scope for this change.

Subject: [PATCH 120/281] fix(reasoning): thread investigation run_id into LLM
 calls (#39, #59)

decide_next_turn did not forward a run_id to chat_structured, so every
investigation reasoning turn recorded its LLMCostRecord under the
standalone "_no_run" sentinel. Two consequences: the per-investigation
cost display summed nothing and read $0.00, and the forensics freeflow
cost ceiling -- which sums LLMCostRecord.cost_usd for
run_id == investigation_id -- never saw any spend and never fired.

Thread run_id (and team_id) through decide_next_turn and pass
investigation_id from all three researchers (vr, malware, forensics).
Realign the VR live-cost aggregator to sum directly on
run_id == investigation_id instead of joining through TaskRecord (that
join returned 0 once run_id was populated with the investigation id).

Behavior change: the forensics freeflow ceiling (default $25) was inert
and is now functional -- a freeflow investigation is cancelled once its
cumulative LLM cost crosses the configured cap. The per-run token
budget check also now runs for investigations, but stays a no-op unless
an operator configures a non-zero llm_budget_max_total_tokens ceiling.

Tests: reasoning engine forwards run_id to chat_structured; VR
aggregator sums by investigation_id and isolates other investigations;
existing forensics ceiling test now reflects production behavior.

Subject: [PATCH 121/281] fix(llm): abort LLM retry backoff on cancellation
 token (#44)

The per-investigation cancellation token was checked only at the turn
boundary. A pause that landed while a provider call was in its retry
backoff waited out the full retry schedule before the next turn-boundary
poll noticed it. The retry loop now peeks the token before every attempt
via a no-create helper (is_run_cancelled) and raises LLMCancelledError,
so a same-process pause during a backoff aborts within one attempt
instead of paying the remaining retries.

The VR and malware investigation loops catch LLMCancelledError and route
it to the same clean cancellation_token_set exit as the turn-boundary
poll, so a mid-retry cancellation finalises as cancelled rather than
escaping to mark the run FAILED. Forensics keeps its DB-status
turn-boundary cancel; it does not use the token registry, so the
retry-loop peek is a no-op for it (no token is ever created there).

Tests: retry-loop cancellation (pre-abort, mid-retry abort on attempt 2,
no-token no-op) in test_retry_classification.py; VR loop routes
LLMCancelledError to a clean exit in test_vr_phase_b_pause_resume.py.

Subject: [PATCH 122/281] fix(vr): offload blocking PDF render off the event
 loop (#48)

render_investigation_pdf ran two synchronous blocking operations
directly on the event loop: the ReportLab render (_render_pdf,
CPU-bound) and _resolve_audit_metadata (a git subprocess plus a sync
psycopg connection). Both stalled the worker loop for the full duration
of a report export, blocking every other request sharing that worker.

Both now run through run_blocking_io (the platform worker-pool offload).
Output is byte-identical; only the threading changed. The offloaded
callables take already-loaded plain data (the investigation record and
descriptor dict, or the resolved facts and content), so they are safe
to run off-thread -- neither touches the async session.

Test: test_pdf_report_offload.py stubs fact collection, the writer, and
the renderer to assert _render_pdf is dispatched through run_blocking_io
rather than called inline on the loop.

Subject: [PATCH 123/281] fix(vr): offload MASVS report render, correct false
 offload docstring (#48)

The MASVS report.pdf route claimed in its docstring that the ReportLab
render was pushed onto a worker thread via asyncio.to_thread, but the
handler called build_pdf inline on the event loop. The render (up to 53
L1 verdicts plus subsections) stalled the loop for other requests on the
worker; the docstring and the code disagreed.

build_pdf now runs through run_blocking_io (the platform worker-pool
offload), matching the investigation-report endpoint. The docstring and
inline comment are corrected to describe the actual mechanism rather than
the asyncio.to_thread path that was never wired.

Subject: [PATCH 124/281] fix(vulnerability): offload WeasyPrint PDF render off
 the event loop (#48)

PDFReportRenderer.render_bytes_async ran the WeasyPrint HTML-to-PDF
conversion inline; its docstring rationalized the block as unavoidable
because modules must not call asyncio.to_thread. run_blocking_io is the
platform-provided offload helper that modules are allowed to call, so
that rationalization no longer holds. The conversion is now isolated in
the sync _html_to_pdf_bytes primitive and dispatched through
run_blocking_io, keeping the event loop free during the render. The
missing-aila[pdf] ImportError still propagates unchanged from the
offloaded primitive.

Subject: [PATCH 125/281] fix(forensics): skip readiness auto-enqueue when
 analysis already active (#59)

The readiness-check handlers (JSON + SSE) transitioned a project
CREATED to READY and submitted run_forensics_analysis without checking
whether one was already in flight. Two rapid readiness-checks could open
two full pipelines racing on ArtifactRecord inserts.

Both handlers now query for an active (queued/running/waiting)
run_forensics_analysis task carrying this project_id before enqueue and
skip the submit when one exists. MachineReadinessResult gains
already_queued + existing_task_id so the JSON caller sees the skip; the
SSE done event carries the same fields. The task fn_path is derived from
the callable the same way TaskQueue.submit stores it, so a future module
move does not silently break the match.

Test: test_readiness_idempotent_enqueue.py exercises the guard helper --
active analysis task detected, terminal task ignored, other project
ignored, and a same-project investigation task (different fn_path) not
counted as an active analysis.

Subject: [PATCH 126/281] fix(reasoning): reject non-JSON observables at
 construction (#61)

ReasoningCaseState.observables and ReasoningTurnDecision.observables were
dict[str, Any] with no serializability guard. A datetime, bytes, or set
entering observables passed Pydantic construction, survived every
in-process mutation, and only crashed later at model_dump(mode='json')
or task_queue.submit -- far from the code that introduced it. Both
fields are now typed ObservablesDict, an Annotated dict carrying an
AfterValidator that runs one json.dumps and raises at the source with
the offending path.

Observables originate from LLM JSON output and the loop injects only
str/int/dict/list, so no current path regresses; the guard catches
future code bugs where they happen.

Test: datetime and bytes observables raise on both models; the
str/int/nested-dict/list shapes the loop actually stores pass.

Subject: [PATCH 127/281] fix(reporting): team-scope scheduled report records
 (#48)

ScheduledReportRecord had no team_id: the scheduled-reports CRUD
endpoints listed every team's schedules and resolved single resources by
bare primary key, so a team-scoped admin could read, edit, delete, or
trigger another team's schedule. God-tier admins (team_id=NULL, TEAM-06)
are intended to see all.

ScheduledReportRecord now carries team_id via TeamScopedMixin (migration
073, nullable per the mixin convention, best-effort backfill from
user_records via created_by). create stamps team_id from the caller;
list filters to the caller's team when team-scoped; update/delete/trigger
resolve rows through a team predicate and return 404 across the team
boundary so existence does not leak. God-tier callers (team_id=None) skip
the filter and see all.

Test: create stamps team_id; list is team-scoped; god-tier sees all;
cross-team patch/delete/trigger return 404 with the row untouched;
own-team delete succeeds.

+"""073 -- team-scope scheduled_report_records (#48-6).
+
+Adds a nullable, indexed ``team_id`` column to ``scheduled_report_records``
+so the scheduled-reports CRUD endpoints can scope rows to the caller's

+god-tier admin rows carry ``team_id = NULL`` (TEAM-06) and remain visible

+stay NULL (owned by the god-tier view). No NOT NULL constraint is applied

Subject: [PATCH 128/281] fix(api): team-scope audit event queries (#36)

GET /audit/events and GET /audit/events/{run_id} queried AuditEventRecord
(a team-scoped model) with no team predicate, so any authenticated
non-admin could read every team's audit trail, and fetch another team's
run trail by run_id. Both handlers now take the AuthContext and filter by
the caller's team; a god-tier admin (team_id=None, TEAM-06) skips the
filter and sees all. A team-scoped caller reading another team's run_id
receives an empty trail rather than that team's events.

Test: team-scoped list returns only the caller's team; god-tier sees all
teams; cross-team run trail is empty; own-team run trail is visible.

Subject: [PATCH 129/281] fix(malware): team-gate investigation sub-resource
 reads (#36)

Six investigation sub-resource list endpoints (hypotheses, observations,
targets, branches, messages, outcomes) discarded auth and queried by
investigation_id with no team check, so any authenticated principal could
read another team's investigation internals by id. Each now opens a
team_context-bound UnitOfWork and gates the parent investigation through
owned_or_404 before reading children, matching the existing
reasoning-graph handler. A team-scoped caller addressing another team's
investigation gets 404; a god-tier admin (team_id=None) sees all.

Test: parametrized cross-team 404 across all six endpoints; own-team and
god-tier reads pass the gate.

Subject: [PATCH 130/281] fix(malware): team-scope target/workspace/outcome
 sub-resource reads (#36)

Four more sub-resource list endpoints leaked across teams:
list_observations (by target), list_families and list_playbooks (by
workspace) queried team-scoped rows without binding team_context, and
list_outcome_reviews (by outcome) queried review rows that carry no
team_id. The first three now open a team_context-bound UnitOfWork so the
team-scope listener filters rows to the caller's team (god-tier sees
all); outcome reviews gate via the parent outcome's investigation through
owned_or_404.

Test: outcome-reviews cross-team read returns 404; own-team read passes.

Subject: [PATCH 131/281] fix(vulnerability): team-scope findings queries (#36)

The findings endpoints read and mutated LatestFindingRecord (team-scoped)
with no team predicate: list_findings and get_findings_facets bound auth
as an unused _key and ran bare UnitOfWork queries, so every authenticated
principal saw and counted all teams' findings; get_finding_detail and
submit_finding_feedback resolved a finding by id with no team check; and
bulk_update_findings could mutate another team's findings.

Each now scopes to the caller's team: list and facets append a team_id
filter to the query filter set (applied to both the count and page/group
statements), detail and feedback 404 on a cross-team finding, and bulk
update rejects cross-team ids at the preflight (422, no write) plus a
defense-in-depth team predicate on the update. A god-tier admin
(team_id=None, TEAM-06) is unrestricted.

Test: team-scoped list returns only the caller's team; god-tier sees all;
cross-team detail 404; cross-team bulk update 422 with the row untouched.

+"""Cursor-recreation version-chain bug (issue #40-4).
+
+Background
+----------
+``DurableStateMachine._commit_transition`` holds a FOR UPDATE lock on the
+run's ``workflow_state_cursor`` row before advancing it. If the row is
+missing at that point (e.g. the parent_reconciler sweep raced the commit
+and deleted a mid-state cursor), the engine recovers by INSERTing a
+fresh row with the transition's ``new_state`` payload rather than
+raising ``WorkflowConflictError`` and burning an ARQ retry.
+
+Historical bug: the recovery INSERT wrote ``version=1`` unconditionally.
+Callers construct ``new_state`` with ``version=loaded_state.version + 1``
+and ``_commit_transition`` returns that ``new_state`` back to the engine
+loop. The next iteration then calls ``_commit_transition`` with
+``loaded_state = <that returned new_state>`` (version N+1), but the DB
+row is at version 1. The FOR UPDATE reports ``current_version=1`` while
+``loaded_state.version=N+1``; the mismatch check fires and raises
+``WorkflowConflictError``, which under ARQ becomes a spurious retry.
+
+Fix: write ``version=loaded_state.version + 1`` in the recreation
+branch so the in-memory State matches the row the next iteration will
+lock. See ``src/aila/platform/workflows/engine.py`` -- the recreation
+site inside ``_commit_transition``.

+"""#36 -- user management endpoints are team-scoped.
+
+_admin_router mounted GET/POST /users and GET/PATCH /users/{user_id} behind
+_require_admin, but did NOT distinguish a god-tier admin (team_id=None,
+TEAM-06) from a team-scoped admin, so a team-scoped admin could list every
+team's users and read or mutate a user in any other team. UserRecord is
+team-scoped (user_records) and TeamScopedMixin populates the team_id column
+at create time. Each endpoint now:
+
+  * list_users -- adds ``WHERE team_id = auth.team_id`` to the count and
+    list statements when the caller is team-scoped (both are plain selects
+    that bypass the do_orm_execute listener).
+  * get_user -- returns 404 (never 403, so no cross-tenant existence
+    oracle) when the target row's team differs from the caller's.
+  * create_user -- forces the new user's team_id to the caller's team when
+    the caller is team-scoped; a god-tier admin retains the ability to set
+    an arbitrary team_id, including None.
+  * update_user -- applies the same 404 gate before mutating.
+
+Handlers are invoked directly with an explicit AuthContext because the
+router-level dependency stack (require_user_or_api_key, _require_admin)
+is not resolved on a direct call. Query-default and dependency-default
+params are passed explicitly so their FieldInfo sentinels never leak into
+the body. The slowapi limiter is disabled by the autouse fixture in
+tests/api/conftest.py.

+"""Issue #40-1: ``TaskQueue.requeue_failed`` must enqueue an ARQ job for
+every row it re-queues, not just flip ``TaskRecord.status``.
+
+The pre-fix behaviour was to flip ``status='failed'`` -> ``'queued'`` and
+commit without ever calling ``pool.enqueue_job`` for the row, so the DB
+row read as 'queued' forever but no worker ever picked it up. The fix
+enqueues via the shared ``_enqueue_arq_job`` helper (the same code path
+:meth:`TaskQueue.submit` uses) BEFORE flipping the status; rows whose
+enqueue fails stay 'failed' so the caller can retry.
+
+These tests patch the ARQ pool so no live Redis is required. They
+assert BOTH the ARQ side-effect (enqueue call issued with the right
+fn short-name / queue key / job id / kwargs) AND the DB status
+transition.

+``worker._sweep_orphan_running_tasks``'s key-drop pattern.
+
+These tests patch the ARQ pool + the redis client so no live Redis is
+required. They assert BOTH the ARQ side-effect AND the DB status
+transition for every branch.

 AUTO-06: Platform maintenance jobs use module_id='platform'.
+
+Finding 46-7 (see .run/designs/DESIGN_automation_events_reporting.md):
+platform_health_check used to be a log-only no-op. It now probes the
+platform's cheap in-process dependencies (async DB engine round-trip
+and Redis PING when a pool is configured) and returns a structured
+HealthReport. The call is best-effort: any probe failure records that
+dependency as unhealthy and continues; nothing bubbles out of the
+health check itself. Callsite audit: no reader consumes the return
+value today (runner.py submits this action via TaskQueue and only
+records last_run_result), so widening the return type from None to
+HealthReport is additive and safe.

+- Live DB probe returns healthy under the test_db fixture, with Redis

+- A patched DB probe that raises produces status='unhealthy' and does

+- Direct unit tests on _probe_database / _probe_redis pin the isolation
+  boundary so a regression in the wrapper cannot silently rely on the

+"""074 -- automation cron timezone + disable reason (#46-2, #46-4b).
+
+Adds two nullable columns to ``automation_schedule_records`` so the
+runner can (a) evaluate cron expressions against a wall-clock timezone
+and (b) auto-disable schedules that fail to parse without raising on
+every subsequent tick:
+
+- ``cron_timezone`` -- IANA zone name (e.g. ``UTC``, ``America/New_York``).
+  Interpreted by ``AutomationRunner._is_due`` via ``zoneinfo.ZoneInfo``
+  so a schedule like ``0 9 * * *`` fires at 09:00 in that zone rather
+  than 09:00 UTC. NULL and unrecognized names fall back to UTC at
+  read time. A server default of ``'UTC'`` covers existing rows and
+  any future INSERT that omits the column.
+
+- ``disable_reason`` -- short cause populated by the runner when a
+  cron expression or timezone cannot be parsed. The runner also flips
+  ``enabled`` to false so the row is not re-attempted every tick.
+  Operators clear ``disable_reason`` and set ``enabled`` back to true
+  to re-arm the schedule.
+
+Both columns are nullable at the database layer. No index is added:
+neither column participates in the runner's due-selection WHERE, and
+UI listings paginate over an already-narrow team-scoped result set.

+"""Shared SSRF egress policy: address blocklist, URL validation, and httpx
+transports that re-validate every request hop.
+
+Historically the SSRF apparatus lived in ``aila.platform.tools.http`` and only
+``HTTPFetchTool`` (module-agent egress) enforced it, following redirects
+manually so each hop was re-checked. The platform ``build_http_client``
+(used by CVE/provider fetchers and health probes) set ``follow_redirects=True``
+with NO per-hop validation, so an external endpoint could ``301`` the client
+into cloud IMDS (169.254.169.254) or an internal service (issue #42).
+
+The policy now lives here so BOTH layers share one blocklist. The transports
+below validate the request URL before the socket opens; httpx calls a
+transport once per redirect hop, so wrapping the real transport re-checks the
+initial URL and every redirect target without relying on event-hook ordering.

+auditeventrecord.created_at and artifactrecord.created_at are ordered/filtered
+by time (audit trail listing, artifact search ordering, retention cleanup).
+None were indexed, so those scans went sequential on tables that grow without
+bound in production.

+Indexes are created CONCURRENTLY (outside a transaction) so building them does
+not hold a write lock on a large live table. The model side carries index=True

Subject: [PATCH 149/281] fix(knowledge): resolve knowledge_store dedup INSERT
 race idempotently (#37)

KnowledgeStoreTool.forward performed a SELECT-then-INSERT keyed on (namespace, dedup_key) with no handling for the window between the two statements. Two concurrent knowledge_store calls that both miss the lookup then race the INSERT; the loser hit the uq_knowledgeentryrecord_namespace_dedup_key unique constraint and surfaced an unhandled IntegrityError (a 500 to the agent).

forward now catches IntegrityError on the INSERT branch, rolls back, re-reads the winner row, and overwrites it, returning operation=updated. KnowledgeService.store is intentionally left raising on the same collision: its pattern_store caller pairs the mirror INSERT with a pattern row in one UnitOfWork and relies on the raise to roll the pair back together, so swallowing there would leak duplicate pattern rows.

Adds a deterministic regression test that forces the losing-race branch by missing the pre-insert lookup once.

Subject: [PATCH 150/281] docs(changelog): reconcile 0.3.0 entry with the
 latest hardening batch

Adds the 2026-07-21 work to the unreleased 0.3.0 entry: task-engine team propagation and team-scoped task reads (#53), confidence-drift retention sweep and hot-column indexes (#45), team ownership on the topology/users/dashboard/executive/search/audit/findings/scheduled-report reads (#36, #48), the knowledge embedding-provider unification plus relevance floor and dedup INSERT race resolution (#37), requeue/resume/cancel ARQ side-effects and cursor version-chain preservation (#40), timezone-aware cron with auto-disable, SKIP LOCKED, and real health probes (#46), and the malware dict-payload cap (#61). Dates the entry to release-finalization day.

Subject: [PATCH 151/281] fix(platform): stamp workflow runs with the
 submitting team (#36)

report.py and the module health-summary fallback filter WorkflowRunRecord by team_id for team-scoped callers, but the run-record creation paths never set it. Every WorkflowRunRecord landed with team_id NULL, so a team user saw none of their own scan reports or workflow runs -- only god-tier callers (no filter) could see them.

orchestrator.handle now takes an optional team_id and stamps it on the run record; run_platform_handle threads ctx.team_id (the queued-scan path), sessions.py passes auth.team_id (interactive dispatch), and _ensure_run_record reads the task-engine team context var (the dispatcher engine path). CLI and other contextless callers leave it None, unchanged. No run that was previously visible becomes hidden.

Tests: _ensure_run_record stamps from the context var and stays None outside a task; run_platform_handle forwards ctx.team_id into handle. Updates the scans entrypoint arg assertion for the new team_id kwarg.

Subject: [PATCH 152/281] fix(vulnerability): stamp findings with the scan
 team, scope scheduled reports (#36)

The vulnerability findings list, executive, search, and dashboard reads all filter LatestFindingRecord by team_id, but the persist state wrote every finding team-less (core sa_insert bypasses the team-scope listener). A team user therefore saw zero findings -- the entire findings surface was invisible to non-god-tier callers. state_persist now stamps each LatestFindingRecord with the scan's team from the task-engine context var.

The scheduled-report worker read findings on a session with no team context, so a team's risk-summary PDF included every team's findings. latest_findings gains an explicit team_id filter param, and the worker passes the report owner's team_id (None stays god-tier).

Test: latest_findings(team_id=...) scopes to one team on a context-free session and returns all teams for team_id=None.

Subject: [PATCH 153/281] fix(platform): stamp team on agent-tool system
 registration (#36)

The REST system-create path stamps team_id=auth.team_id, but the system_registry agent tool wrote ManagedSystemRecord team-less. A system an agent registered on a team's behalf was then invisible to that team's scoped reads (systems list, dashboard, search, topology). The tool insert now stamps the team from the task-engine context var; bootstrap and CLI paths (no task) stay god-tier as before.

Test: the tool stamps the context-var team on insert, and leaves team_id None outside a task.

Subject: [PATCH 154/281] fix(platform): stamp audit events with the acting
 team (#36)

GET /audit filters AuditEventRecord by team_id, but record_audit_event never stamped it, so team-scoped users saw an empty audit trail. record_audit_event now takes a team_id param and falls back to the task-engine context var. Request handlers (auth, config, scans, sessions, systems, tasks, tools, users, vulnerability findings-bulk) pass the acting principal's team; worker and workflow events inherit the running task's team via the context var; pre-authentication login failures stay team-less.

Test: record_audit_event stamps an explicit team_id, falls back to the context var when omitted, and stays None when neither is present.

Subject: [PATCH 155/281] fix(auth): team-scope API keys on create, list, and
 revoke (#36)

API keys were written team-less and list_api_keys had no team filter, so a team-scoped admin could enumerate every team's key metadata (prefix, label, role, created_by) and revoke another team's key by id. create now stamps team_id from the creating admin (god-tier admins mint team-less keys); list filters to the admin's team; revoke returns 404 for a cross-team key id (no existence oracle). A god-tier admin (team_id=None) is unrestricted.

Test: create stamps the admin's team, god-tier keys stay team-less, list is team-filtered while god-tier sees all, and a cross-team revoke 404s while the owning team succeeds.

Subject: [PATCH 156/281] fix(auth): scope OIDC users to a team, carry team in
 the JWT (#36)

The OIDC callback issued the access and refresh JWTs without a team_id claim, so a team-assigned OIDC user was treated as god-tier (TEAM-06) for the token lifetime, and auto-provisioned users had no team at all. The callback now stamps the new user with the provider's default_team_id and passes the user's team into both issued JWTs; a user left team-less still gets god-tier but the grant is logged.

Adds OIDCProviderRecord.default_team_id (create/update/response + migration 076) so an admin can bind a provider to a team that its auto-provisioned users join on first login.

Test: issue_user_jwt carries the team claim (None when absent); provider create/update persist and return default_team_id.

Subject: [PATCH 157/281] fix(knowledge): store embeddings at full 1024-dim
 BGE-M3 (#49)

The pgvector column was Vector(384) while the default BGE-M3 provider emits 1024-dim vectors, so KnowledgeService.embed truncated every vector to its first 384 components on store and query, discarding 640 dimensions and degrading retrieval below native MiniLM. Widen the column to Vector(1024), set the service target dimension to 1024 (MiniLM now zero-pads up instead of BGE truncating down), and skip null-embedding rows in the retrieve vector leg. Migration 077 clears the prior truncated vectors and re-widens the column; scripts/reembed_knowledge.py backfills full 1024-dim vectors from stored content.

+"""Widen knowledge embedding to vector(1024) and clear truncated vectors.
+
+The ORM model and KnowledgeService previously truncated BGE-M3's 1024-dim
+output down to a Vector(384) column, discarding 640 dimensions on every store
+and query. This migration makes the column match BGE-M3 at full width.
+
+Existing vectors were stored either truncated-to-384 or as an earlier
+zero-padded shape; neither is a valid 1024-dim BGE-M3 embedding, and pgvector
+cannot cast 384-dim rows into a vector(1024) typmod. The column is therefore
+cleared (set NULL) before the type change; run ``scripts/reembed_knowledge.py``
+afterwards to re-embed every row from its stored ``content`` at full 1024 dims.
+Retrieval degrades to full-text-only for rows with a NULL embedding until the
+backfill completes (the vector leg skips NULL embeddings).

Alembic-migrated databases raised a 500 on every login (column does not exist); fresh create_all installs and tests masked it because the model carries the columns.

Subject: [PATCH 161/281] feat(config): typed dynamic-key families for
 per-task-type config (#45)

ConfigRegistry rejected any key not declared as a static schema field, so the LLM routing defaults, llm_kill_switch, and every per-task-type / per-team key were env-only ghost keys that PUT /config refused. Add DynamicKeyFamily: a schema declares typed key families (prefix + value_type + default) in __dynamic_families__, and get/get_sync/set resolve a key to the static field or the longest-matching family, so an open key space is settable and cast through one contract. Declare the six static llm_* keys (defaults matching the prior hardcoded fallbacks) and the per-task-type/per-team families on PlatformConfigSchema. Behavior-preserving on read; makes the keys settable via the config API.

Subject: [PATCH 162/281] feat(knowledge): select embedding provider from
 platform config (#49)

KnowledgeService always constructed resolve_provider() with no argument, so the knowledge_embedding_model key its docstrings referenced did nothing and was not even a declared config key. Declare knowledge_embedding_model on PlatformConfigSchema (default bge-m3) and resolve it once (memoized) at KnowledgeService construction, so an operator can select the provider via PUT /config. Correct the stale docstrings and the leftover 384-dim truncation comments in the knowledge tool.

Subject: [PATCH 163/281] fix(config): honor declared config keys via
 ConfigRegistry (#45)

Several declared config keys were read from a compiled constant, a fresh schema default, or a VR_* env var instead of ConfigRegistry, so PUT /config overrides were silently dropped. Wire them through the registry: platform is_step_enabled reads llm_pipeline_{step}_default and the budget ceiling reads llm_budget_max_total_tokens_default, the reaper reads its thresholds via get_task_tuning; VRWorkflowServices resolves VRConfigSchema from the registry and the VR_* cap reads move to a vr config_helpers mirroring malware; forensics reads its SSH/script/collection timeouts, freeflow attempt cap, and llm_model from the forensics namespace. Defaults are byte-equal to the prior values, so resolution is behavior-preserving until an operator sets an override. Adds a resolver test for the dynamic-key families.

Subject: [PATCH 164/281] fix(storage): reconcile model-vs-migration schema
 drift (#45)

Fresh installs build schema from the SQLModel models via create_all while production runs Alembic; several tables had diverged. Widen scheduled_report_records.team_id, the reasoning_graph_snapshots identifier columns, and automation_schedule_records.cron_timezone to TEXT (migration 080); promote the team_records unique index to the named constraint the model declares; prefix the VR workspace and tag-index unique constraints (migration 081) so they no longer share an unqualified name with malware; align the VR auto_steering_key (composite), is_favorite (partial), and project_id (TEXT) model shapes to what migrations 063/058/040 already built; and drop the redundant standalone per-column indexes create_all added on platform_journal that migration 071 never built. Migrations are guarded and reversible.

+"""081 -- reconcile VR module schema drift (model vs migration).
+
+Two named UNIQUE constraints on VR module tables shared the same
+un-prefixed name as their malware counterparts before malware was
+prefixed in migration 068. Migration 068 renamed the malware-side
+constraints; the VR-side constraints kept their generic names. This
+migration prefixes both VR constraints so the model and the migrated
+production database converge on the same names, matching the wider
+per-module naming convention (CLAUDE.md Common Mistake #21).
+
+Renames (guarded with ``IF EXISTS`` so a re-run on a database that
+already carries the new names is a no-op):
+
+  - ``vr_workspaces``: ``uq_workspace_team_slug`` -> ``uq_vr_workspace_team_slug``
+  - ``vr_target_tag_index``: ``uq_target_tag_source`` -> ``uq_vr_target_tag_source``
+
+No column or index shape changes are needed on the migration side: the
+composite index built by migration 063 on
+``vr_investigation_messages(investigation_id, auto_steering_key)``,
+the partial index built by migration 058 on
+``vr_investigations.is_favorite`` (``WHERE is_favorite = true``), and
+the unbounded ``vr_findings.project_id TEXT`` column from migration
+040 are already the production truth. The SQLModel models in
+``src/aila/modules/vr/db_models/`` are being aligned to them in the
+same commit so ``create_all`` (tests, fresh installs) matches
+production.

Subject: [PATCH 165/281] docs(config,storage): define landed config and schema
 changes in design docs

Sync the design docs with this session's landed changes. CONFIG_REGISTRY.md gains a Dynamic key families section describing the DynamicKeyFamily mechanism, the six newly-declared static llm_* keys plus knowledge_embedding_model in the Platform Config Fields table, and the VR and forensics config namespaces. LLM_INTEGRATION.md adds llm_tool_timeout_s, llm_data_direction, llm_monthly_budget_usd, and the pipeline step-order keys. ENV_VARS.md no longer claims the llm routing defaults are absent from PlatformConfigSchema. DB_SCHEMA.md records the knowledge embedding as 1024-dim BGE-M3, and the Alembic head moves 067 -> 081 across DB_SCHEMA.md, DATABASE_MIGRATIONS.md, and vr/07_DATA_MODEL.md with migrations 068-081 catalogued.

+## Dynamic key families
+
+Some configuration is per-task-type or per-team, so the key space is open (for
+example `llm_model_{task_type}` or `llm_monthly_budget_usd_{team_id}`) and
+cannot be enumerated as a fixed set of schema fields. A namespace schema
+declares typed dynamic-key families in a `__dynamic_families__` class
+attribute; each family carries a prefix, a `value_type`, and a default. When a
+key does not match an exact static field, ConfigRegistry resolves it to the
+longest-matching family, so the key is settable through `PUT /config` and cast
+on read exactly as a static field is. A key that matches no static field and
+no family is rejected by `set`.
+
+The `platform` namespace declares the following families:
+

+| `llm_budget_max_total_tokens_` | int | Per-task-type token budget ceiling |

+| `llm_pipeline_gate_high_threshold_` | float | Per-task-type HIGH-confidence gate threshold |

 ### AILA_PLATFORM_LLM_DEFAULT_MODEL / _BASE_URL / _DEFAULT_MAX_TOKENS
 
+- **Defaults:** `antigravity/claude-opus-4-6-thinking`, `https://openrouter.ai/api/v1`, `4096` (from `PlatformConfigSchema`).
 - **Used in:** `src/aila/platform/llm/config.py` (`LLMConfigResolver`)
-- **Resolution:** ConfigRegistry env-var override path. These keys live under the `platform` namespace but are NOT in `PlatformConfigSchema` -- the env var sets the value, the DB row carries persistent overrides, and the resolver bakes in its own fallbacks (`openai/gpt-4o-mini`, `https://openrouter.ai/api/v1`, `4096`) when nothing matches.
-- **Production guidance:** Set per deployment to pin the default model/provider for every task type. Per-task-type overrides land under `AILA_PLATFORM_LLM_MODEL_<TASK_TYPE>` and `AILA_PLATFORM_LLM_MAX_TOKENS_<TASK_TYPE>`.
+- **Resolution:** Declared as static fields on `PlatformConfigSchema` under the `platform` namespace. Reads go through the standard ConfigRegistry chain (env var, then in-memory cache, then the persisted DB row, then the schema default). The env var wins over the DB, so setting `AILA_PLATFORM_LLM_DEFAULT_MODEL` overrides any value stored through `PUT /config/platform/llm_default_model`.
+- **Production guidance:** Set per deployment to pin the default model, provider base URL, and completion ceiling for every task type. Runtime edits without a restart go through `PUT /config/platform/llm_default_model` (and its `_base_url` / `_default_max_tokens` siblings). Per-task-type overrides land under `AILA_PLATFORM_LLM_MODEL_<TASK_TYPE>` and `AILA_PLATFORM_LLM_MAX_TOKENS_<TASK_TYPE>`, or via the same `PUT /config` endpoint against the matching dynamic-key family.

Subject: [PATCH 166/281] refactor(imports): canonicalize platform _common
 imports to public paths (#30)

Rewrite all cross-package imports of aila.platform.contracts._common and aila.platform.tools._common to their public package entrypoints. utc_now/JsonObject/ActionId/JsonScalar/JsonValue resolve through aila.platform.contracts; Tool resolves through aila.platform.tools. Both packages already re-export these symbols in __all__, so callers no longer reach into private _common modules. No behavior change.

Subject: [PATCH 167/281] fix(resilience): flip fail-open recovery paths to
 fail-closed (#31)

RFC-07 phase 0. Three recovery paths returned a permissive value on failure and hid the fault:

- TaskQueue._compute_investigation_defer returned 0.0 on any DB error, so the investigation rate limiter stopped deferring under DB pressure and flooded the queue. It now catches DB/OS/timeout errors and returns one bounded defer step (self-clearing on the next healthy read).

- The verify pipeline step caught every exception, set verification_status='error' (a value with no consumer), and continued -- silently disabling the verification gate. It now re-raises so PipelineRunner applies the security-critical fail-closed default and blocks the unverified response.

- Malware's synthesize_no_finding_outcomes had no LLM-health guard, so an LLM outage that drove branches terminal was recorded as a clean no-finding audit. Ported the guard already present in the VR finalizer and malware's abandon_stale_branches_impl. Pipeline post-call fail-mode default and SSE-write logging/counting were already fail-closed in prior work; no change needed there.

Tests: verify re-raise, defer bounded back-off, malware guard short-circuit.

Subject: [PATCH 168/281] fix(contracts): make ModulePayload a real
 discriminated union (#61)

PlatformResponse.module_payload was a plain first-match union: a dict with unexpected fields silently matched the wrong member (e.g. the orchestrator's unroutable {supported_actions} and every forensics/hello_world/_template free-form result dict matched an empty PlatformRegistryPayload, dropping their data).

Key it on query_mode via Field(discriminator=...): each Vuln*/Platform* member carries a distinct query_mode literal (added defaulted tags to PlatformRegistryPayload/PlatformCommandPayload, made VulnAnalysisPayload.query_mode required-with-default, added UnroutablePayload). The field type gains a dict[str, Any] arm so free-form module result dicts pass through untyped instead of being coerced. The known construction sites (platform SSH registry/command, orchestrator unroutable, vulnerability analysis) now emit their query_mode tag so they route to the typed member.

Tests: 12-case discriminator routing (typed members, free-form fallback, unknown tag, degenerate missing-report, None, round-trip).

Subject: [PATCH 169/281] feat(observability): correlate cost + MCP-call
 records to investigation/branch/turn (#39)

LLMCostRecord and VRMcpCallLogRecord had no way to attribute a cost or a tool call to the branch/turn that produced it. Add nullable investigation_id/branch_id/turn_number columns to both (migration 082) and an ambient correlation ContextVar (aila.platform.llm.correlation): the VR and malware turn loops set it around decide_next_turn, and persist_cost_record + the VR MCP-call logger read it via current_join_keys(). Calls outside a turn leave the columns null. Models + migration + tests ship together so create_all (tests) and the migrated schema converge.

Tests: ContextVar set/reset/nesting; DB round-trips proving a cost record and an MCP-call log written inside a scope carry the join keys, and are null outside one.

 ### Added
 
+- Observability join keys on cost and MCP-call records (#39):
+  `llm_cost_records` and `vr_mcp_call_log` gain nullable
+  `investigation_id`, `branch_id`, and `turn_number` columns. The agent
+  turn loop sets an ambient correlation (a ContextVar) before it drives
+  the LLM and MCP calls, and the cost-record writer and VR MCP-call
+  logger stamp it, so a cost row or a tool-call row can be joined back to
+  the investigation, branch, and turn that produced it. Calls outside a
+  turn (scoring, report generation) leave the columns null. Migration
+  082 adds the columns and their indexes.
 - Append-only, hash-chained platform journal for tamper-evident audit;
   the CLI audit trail now writes to it. (C2)
 - Evidence packs sealed with a merkle digest so later tampering is

Subject: [PATCH 170/281] feat(contracts): hoist shared enums, contracts, and
 constraint-naming helper (#26)

RFC-01 Phase 0a (additive scaffolding, no module change yet). Adds:

- platform/contracts/_naming.py: TabledUq + TableDerivedConstraintsMixin. A base declares TabledUq(cols, suffix=...) and a concrete subclass's __init_subclass__ materializes UniqueConstraint named uq_{__tablename__}_{suffix}, so two modules can no longer collide on a shared constraint name (RFC-00 Common Mistake #21). Verified: vr/malware concrete tables get distinct names, abstract bases stay unmapped.

- platform/contracts/enums.py: the 19 shared StrEnums (WorkspaceStatus..StageName), single source of truth. WorkspaceTheme stays module-owned by design.

- platform/contracts/hypothesis.py, evidence_graph.py, target_stages.py: the three byte-identical contract modules, with enums imported from platform.contracts.enums.

Fidelity test proves every hoisted enum is member-for-member and value-for-value identical to both the vr and malware definitions, so the Phase-1 re-export is behavior-preserving.

Subject: [PATCH 171/281] feat(contracts): FK-derivation mechanism +
 workspace/branch record bases (#26)

RFC-01 Phase 0b (additive). The RFC's @declared_attr FK design is incompatible with SQLModel: a non-annotated declared_attr class attribute raises PydanticUserError under SQLModel's Pydantic v2 metaclass. Replaced with TabledFk: the FK column is a plain field on the base and TableDerivedConstraintsMixin derives the ForeignKeyConstraint from the subclass's tablename class vars (parent-table for cross refs, own tablename for self refs). Verified end to end: a concrete subclass gets the right columns and FK targets, and the abstract base registers no table.

Adds WorkspaceRecordBase (+ Summary/Create/Patch contract bases) and the zero-domain BranchRecordBase (+ Summary base) as the two exemplar patterns (domain + zero-domain, FK + non-FK) the remaining bases follow. A shape test proves each base carries exactly the field set of the current vr concrete record, so a Phase-2 subclass reproduces the schema.

Subject: [PATCH 172/281] feat(contracts): add the remaining 9 RFC-01 record +
 contract bases (#26)

RFC-01 Phase 0 record bases complete (11 total with workspace/branch). Each mirrors the vr concrete's shared column set exactly; module-specific residue stays off the base (malware target parent_target_id/sha256; malware investigation analysis_depth/inherit_observations; malware message acked_at; vr project cve_id/patched_target_id/poc_system_id). analysis_system_id was confirmed shared (both modules) and kept on the project base. mcp_call_log excludes the vr-only #39 join-keys (investigation_id/branch_id/turn_number) since malware has not grown them yet. FK columns are plain fields; TabledFk derives the ForeignKeyConstraints from subclass tablename class vars, and now threads ondelete so outcome_review's CASCADE FKs are preserved. A shape test proves every base's field set equals its vr concrete minus the declared residue.

Subject: [PATCH 173/281] refactor(contracts): vr + malware re-export hoisted
 enums and contracts (#26)

RFC-01 Phase 1 (behavior-preserving, no DDL). The vr and malware contract modules now import the 19 shared StrEnums from aila.platform.contracts.enums instead of each declaring a byte-identical copy, and hypothesis.py / evidence_graph.py / target_stages.py collapse to explicit re-exports of the hoisted platform modules. Module-specific enums (WorkspaceTheme, TargetKind, AnalysisDepth, InvestigationKind, OutcomeKind, PatternKind) stay module-owned. Every import site keeps resolving -- the re-exported names are the same objects, and 114 contract + vr + malware tests pass unchanged.

Subject: [PATCH 174/281] fix(contracts): record bases use sa_type not shared
 Column instances (#26)

A base that declares a column via sa_column=Column(...) shares that single Column instance across every table=True subclass, so the second module to subclass it raised 'Column already assigned to Table'. The RFC's base design would have made every base unsubclassable by two modules. Switched all Text columns to sa_type=Text (SQLModel builds a fresh Column per subclass) with sa_column_kwargs threading nullable/server_default/name. Column(Text) defaults to nullable=True while a non-Optional str + sa_type infers NOT NULL, so every converted field carries sa_column_kwargs={'nullable': True} to preserve the original nullability; target's _mcp_handles_json keeps its custom column name via sa_column_kwargs name.

Phase 2 begins: the vr and malware mcp_call_log concretes now subclass McpCallLogRecordBase (vr keeps the #39 join-key residue). Verified both build with identical columns/types/nullability and no shared-instance error; mcp_call_log has no named constraints so no migration is needed.

Subject: [PATCH 175/281] refactor(db): zero-domain records subclass platform
 bases (#26)

RFC-01 Phase 2 (zero-domain tables). The vr and malware outcome, branch, outcome_review, and investigation_target concretes now subclass their platform bases, dropping the duplicated column declarations. Behavior-preserving: columns, FK targets, and ON DELETE CASCADE (outcome_review) are reproduced by the bases; FK constraint names stay Postgres-default (stable). outcome/branch carry no named unique constraint and outcome_review's derived name already matched, so only investigation_target needed a rename -- migration 083 renames uq_<module>_investigation_target to the derived uq_<module>_investigation_targets_investigation_target. mcp_call_log was converted in the prior commit. Verified: subclass wiring, derived constraint names, CASCADE preservation, vr mcp join-key residue; 62 contract + module tests pass.

+"""083 -- rename investigation_target unique constraints to the derived form (#26).
+
+RFC-01 Phase 2 derives every constraint name structurally from the concrete
+``__tablename__`` via ``TabledUq``. The investigation_target join tables carried
+a hand-written name (``uq_<module>_investigation_target``) that does not match
+the derived ``uq_<tablename>_investigation_target``. Rename both so the model
+(``create_all`` on fresh installs / tests) and the migrated production database
+converge on the same name.
+
+Guarded with ``IF EXISTS`` so a re-run, or a fresh database that already carries
+the derived name, is a no-op.

Subject: [PATCH 176/281] refactor(db): domain records subclass platform bases
 (#26)

RFC-01 Phase 2 (domain tables). The vr and malware workspace, target, target_tag_index, investigation, message, pattern, and project concretes now subclass their platform bases, dropping the duplicated shared-column declarations. Module-specific residue stays on the concrete: malware target keeps parent_target_id + sha256; malware investigation keeps analysis_depth + inherit_observations + its kind/strategy_family default overrides; malware message keeps acked_at; vr project keeps cve_id + patched_target_id + poc_system_id. analysis_system_id is shared and lives on the project base.

Module-specific index shapes are re-declared on each concrete, matching the pre-refactor behavior: vr message keeps its composite (investigation_id, auto_steering_key) index and malware message its full-column auto_steering_key index; vr investigation keeps its partial is_favorite index and malware investigation its full-column is_favorite index.

Constraint names now derive from the concrete tablename. Migration 084 renames the workspace and target_tag_index unique constraints to the derived form (uq_<module>_workspaces_team_slug, uq_<module>_target_tag_index_target_tag_source); the other domain tables carry no named unique constraint and single-column foreign keys keep the Postgres default name. Verified: subclass wiring, derived constraint names, residue placement, and the per-module index split; 68 contract + module tests pass.

+"""084 -- rename workspace + target-tag-index unique constraints to the derived form (#26).
+
+RFC-01 Phase 2 (domain tables). The workspace and target_tag_index concretes
+now derive their unique-constraint names structurally from the concrete
+``__tablename__`` via ``TabledUq``:
+
+  uq_<module>_workspace_team_slug   -> uq_<module>_workspaces_team_slug
+  uq_<module>_target_tag_source     -> uq_<module>_target_tag_index_target_tag_source
+
+The other domain tables (investigation, message, pattern, project) carry no
+named unique constraint, so they need no rename. Single-column foreign keys
+keep the Postgres default ``<table>_<col>_fkey`` name and are untouched.
+
+Guarded with ``IF EXISTS`` so a re-run, or a fresh database that already
+carries the derived name, is a no-op.

Subject: [PATCH 177/281] feat(template): db_models scaffold subclassing
 platform bases (#26)

RFC-01 Phase 0 leftover. The _template module now ships a db_models package demonstrating the base-subclass pattern for every platform record base (workspace, target, target_tag_index, investigation, message, branch, outcome, outcome_review, mcp_call_log, investigation_target, pattern, project). A new module copied from _template starts from the platform bases instead of recreating shared columns. The _template package is skipped by module discovery (leading underscore), so these tables never register in the live schema or in migrations. target.py and project.py carry commented residue examples; investigation.py and message.py show the per-module Index pattern.

Subject: [PATCH 178/281] feat(honesty): add RFC-01 re-duplication guardrail
 rules (#26)

Three AST-based honesty-audit rules close the RFC-01 enforcement loop, preventing the deduplicated code from regressing:

34 hoisted_enum_redeclared: a vr/malware contracts file must import the 19 hoisted enums from platform.contracts.enums, not redeclare a StrEnum of the same name. Scoped to the unified modules so forensics/vulnerability keep their own same-named enums (their InvestigationStatus carries different members and is legitimately independent).

35 unnamed_derived_constraint: a unified vr/malware investigation-engine table must derive its unique-constraint name from the tablename via TabledUq, not hard-code a literal. Scoped to the 12 unified table roles so other modules keep their existing hand-named constraints.

36 shadowed_platform_base: a unified vr/malware table whose role maps to a platform base must subclass that base, not recreate four or more of its columns. The base field set is read from platform/contracts via AST (cached, defensive: an unresolvable base skips rather than raising).

All three scope to modules vr+malware (the modules RFC-01 unified); forensics and vulnerability are untouched. Verified: 0 findings on the current tree, and 10 fixture tests prove each rule fires on a violation and stays silent on the correct pattern and on out-of-scope modules. 73 honesty-audit tests pass.

 TeamScopedMixin order (#26)

Closes the RFC-01 risk-mitigation gap: a test now asserts every vr/malware concrete record keeps TeamScopedMixin ahead of SQLModel in its MRO and resolves its platform record base. Covers all 24 concretes across both modules.

Subject: [PATCH 180/281] fix(config): route scheduled-report trigger through
 the shared registry (#45)

The manual scheduled-report trigger handler constructed a bare ConfigRegistry() with no registered schema, producing schema-less reads and a second DB session outside the request. Route it through the request-scoped get_config_registry(request) dependency (the same shared, schema-validated registry every other router uses), removing the unregistered instance and the extra session. redis_url resolution is unchanged.

Subject: [PATCH 181/281] refactor(tasks): lift arq_purge to the platform (#29)

RFC-04 Phase 0 (first of the zero-delta support-service lifts). The ARQ purge primitive was duplicated verbatim in vr and malware services; it carries no record-model coupling, only a module track string. Move it to aila.platform.tasks.arq_purge, make track a required keyword argument (the caller's module supplies its own queue name; the function never names a module), and re-point all seven call sites (each already passes track explicitly). Both module copies are deleted; nothing re-exported them, so this is a clean cutover with no compatibility shim. Behavior-preserving: identical purge logic, same call arguments. Verified: compile/ruff/honesty clean, app imports, 52 vr+malware module tests pass.

Subject: [PATCH 182/281] refactor(services): lift branch_cleanup to the
 platform (#29)

RFC-04 Phase 0 (second zero-delta support-service lift). The orphan-branch cleanup helper was duplicated verbatim in vr and malware; its only module coupling was the branch table name baked into the raw UPDATE. Move it to aila.platform.services.branch_cleanup with branch_table as a required keyword argument (the caller's module supplies its own table name; the function never names a module) and re-point all twelve call sites across both modules, each passing its concrete branch table. Both module copies are deleted (clean cutover, no re-export existed). Stale in-code path references to the old module path were updated. Behavior-preserving: identical UPDATE, same excluded statuses, caller-owned transaction. Verified: compile/ruff/honesty clean, app imports, 52 vr+malware module tests pass.

-"""Orphan-branch cleanup on investigation completion (Phase C surgical).
-
-When an investigation transitions to a terminal status (COMPLETED /
-FAILED / ABANDONED), every branch still in a non-terminal projection
-status (``active`` / ``paused``) MUST be moved to ``abandoned`` with
-``closed_reason='investigation_completed'`` so the operator-facing
-projection is consistent.
-
-Observed gap that motivated this helper (inv ``<inv-uuid>``):
-
-  - 5 of 6 branches reached ``terminal_submit`` and were marked
-    ``status='completed'`` with ``closed_reason='terminal_submit'``.
-  - 1 branch (``wei`` / ``bcaa1f82``) stayed ``status='active'`` with
-    44 turns and growing.
-  - parent_reconciler / cap-check / re-enqueue thrashing flipped
-    ``inv.status='completed'`` while ``wei`` was momentarily not
-    ``active`` (stale-detector abandonment race), then ``wei`` came
-    back and kept advancing turns under a ``completed`` investigation.
-  - Observed: a completed investigation with one branch still
-    pulsing -- no UI signal that ``wei`` was effectively orphaned.
-
-The Phase C full design replaces the 3 reaper/synth paths with a
-single ``investigation_finalize`` workflow state. That structural
-change is large (delete 3 files, add a new state, port behavior). This
-helper closes the operator-visible BUG with one inline UPDATE called
-from every completion site, deferring the structural rewrite to a
-focused follow-up PR.
-
-Contract:
-  - Caller passes a ``UnitOfWork`` whose session is mid-transaction.
-  - Helper UPDATEs ``malware_investigation_branches`` only -- no commit, no
-    flush; that is the caller's responsibility. This lets the caller
-    bundle branch-cleanup atomicity with their existing inv.status
-    write.
-  - Helper does NOT close branches in ``completed`` / ``abandoned`` /
-    ``merged`` / ``promoted`` -- those are correct terminal states the
-    branch reached on its own merit.
-  - Returns the count of branches transitioned for log visibility.
-
-Closes the operator-visible bug on inv ``<inv-uuid>`` (BLOCK) without
-the structural rewrite Phase C originally specified.

-"""Orphan-branch cleanup on investigation completion (Phase C surgical).
-
-When an investigation transitions to a terminal status (COMPLETED /
-FAILED / ABANDONED), every branch still in a non-terminal projection
-status (``active`` / ``paused``) MUST be moved to ``abandoned`` with
-``closed_reason='investigation_completed'`` so the operator-facing
-projection is consistent.
-
-Observed gap that motivated this helper (inv ``<inv-uuid>``):
-
-  - 5 of 6 branches reached ``terminal_submit`` and were marked
-    ``status='completed'`` with ``closed_reason='terminal_submit'``.
-  - 1 branch (``wei`` / ``bcaa1f82``) stayed ``status='active'`` with
-    44 turns and growing.
-  - parent_reconciler / cap-check / re-enqueue thrashing flipped
-    ``inv.status='completed'`` while ``wei`` was momentarily not
-    ``active`` (stale-detector abandonment race), then ``wei`` came
-    back and kept advancing turns under a ``completed`` investigation.
-  - Observed: a completed investigation with one branch still
-    pulsing -- no UI signal that ``wei`` was effectively orphaned.
-
-The Phase C full design replaces the 3 reaper/synth paths with a
-single ``investigation_finalize`` workflow state. That structural
-change is large (delete 3 files, add a new state, port behavior). This
-helper closes the operator-visible BUG with one inline UPDATE called
-from every completion site, deferring the structural rewrite to a
-focused follow-up PR.
-
-Contract:
-  - Caller passes a ``UnitOfWork`` whose session is mid-transaction.
-  - Helper UPDATEs ``vr_investigation_branches`` only -- no commit, no
-    flush; that is the caller's responsibility. This lets the caller
-    bundle branch-cleanup atomicity with their existing inv.status
-    write.
-  - Helper does NOT close branches in ``completed`` / ``abandoned`` /
-    ``merged`` / ``promoted`` -- those are correct terminal states the
-    branch reached on its own merit.
-  - Returns the count of branches transitioned for log visibility.

Subject: [PATCH 183/281] refactor(services): lift machine_readiness to the
 platform (#29)

RFC-04 Phase 0 (third zero-delta support-service lift). The vr and malware machine-readiness checkers were byte-identical apart from class naming and are currently uncalled in both modules. Consolidate into one platform MachineReadinessService generic over the tool-requirements path (the caller supplies its module data/tool_requirements.json path at construction; the service never names a module) with unprefixed ReadinessResult / ToolCheckResult. Both module copies are deleted; the per-module data files stay module-side. Verified: compile/ruff/honesty clean, app imports.

Subject: [PATCH 184/281] refactor(services): lift branch_reaper to the
 platform (#29)

RFC-04 Phase 0 (fourth zero-delta support-service lift). The orphan-branch reaper was duplicated verbatim in vr and malware, coupling only to the branch + investigation record models in its atomic UPDATE. Move the sweep to aila.platform.services.branch_reaper generic over branch_model + investigation_model (status enums now import from the hoisted platform enums). Each module keeps a five-line branch_reaper that binds the platform sweep to its record models via a module-level functools.partial: the periodic-sweep registry keys re-registration on callable identity, so a stable module-level object is required and an inline partial at the registration site would break the re-registration no-op. module.py registrations are unchanged. Verified: compile/ruff/honesty clean, app imports, both sweeps register with stable identity, 52 vr+malware module tests pass.

-"""Reaper for orphan malware investigation branches.
+"""Malware binding of the platform orphan-branch reaper.
 
-Background: an investigation can transition to a terminal status
-(``completed`` / ``failed`` / ``abandoned``) via several paths today --
-cap_exceeded sweep in ``investigation_emit``, the dispatcher's halt-on-
-ship in ``outcome_dispatcher._update_outcome_status``, the operator-
-driven pause-then-complete path that ran before the status_locked fix
-in ``investigation_setup``, and manual DB operator action. Some of
-those paths did NOT cascade to branches, leaving rows with
-``status='active'`` under a terminal parent. The dashboard shows them
-as "still running" forever; the call-stack reasoning treats them as
-in-flight; nothing actually drives them because the worker's per-turn
-status check sees the investigation isn't running and exits the loop.
-
-This reaper cleans them up automatically every minute via the ARQ
-cron, so even when a new code path forgets to halt branches at
-transition time, the orphans get reclaimed within ~1 minute.
-
-Concurrency safety: the sweep is a single ORM ``update()`` statement,
-NOT a Python SELECT-then-UPDATE. SQLAlchemy compiles it to a
-``UPDATE ... FROM ... WHERE ... RETURNING ...`` that PostgreSQL
-evaluates atomically with per-row locks acquired at the UPDATE step.
-So:
-
-  * an operator who restores an investigation (terminal -> running)
-    between query plan and row update simply causes that row to fall
-    out of the match set; the branch is NOT abandoned.
-  * a worker that's commit-racing a branch update holds the row lock
-    first; the reaper waits or sees the branch's updated_at advanced
-    past the touch-grace window, no flip.
-
-Two safety graces baked into the WHERE so even the SQL-atomic version
-doesn't reap branches that are about to be written by some other path:
-
-  (a) the investigation must have been terminal for at least
-      ``_ORPHAN_GRACE_SECONDS`` (5 min). Covers in-flight transitions
-      that are about to halt their own branches.
-  (b) the branch must not have been updated in the last
-      ``_BRANCH_TOUCH_GRACE_SECONDS`` (2 min). Covers worker mid-LLM-call
-      whose commit is in flight.
-
-Both graces are intentionally generous: cost of waiting is a UI
-showing "running" for a few minutes; cost of NOT waiting is a worker's
-commit overwriting the reaper's flip (or vice-versa).
+Binds the platform sweep to the malware record models. Kept as a module-level
+``functools.partial`` so the registered periodic-sweep callable is a stable
+object across re-imports (the sweep registry keys re-registration on callable
+identity, so an inline partial at the registration site would break the
+re-registration no-op).

+"""Reaper for orphan investigation branches.
+
+An investigation can transition to a terminal status (``completed`` / ``failed``
+/ ``abandoned``) via several paths (cap-exceeded sweep, the dispatcher's
+halt-on-ship, the operator pause-then-complete path, manual DB action). Some of
+those paths did not cascade to branches, leaving rows with ``status='active'``
+under a terminal parent. The dashboard shows them as "still running" forever;
+nothing drives them because the worker's per-turn status check sees the
+investigation is not running and exits the loop.
+
+This reaper cleans them up every cron tick, so even when a new code path forgets
+to halt branches at transition time, the orphans get reclaimed within ~1 minute.
+
+Concurrency safety: the sweep is a single ORM ``update()`` statement, NOT a
+Python SELECT-then-UPDATE. SQLAlchemy compiles it to ``UPDATE ... FROM ... WHERE
+... RETURNING`` that PostgreSQL evaluates atomically with per-row locks acquired
+at the UPDATE step. So:
+
+  * an operator who restores an investigation (terminal -> running) between
+    query plan and row update simply causes that row to fall out of the match
+    set; the branch is NOT abandoned.
+  * a worker commit-racing a branch update holds the row lock first; the reaper
+    waits or sees the branch's updated_at advanced past the touch-grace window,
+    no flip.
+
+Two safety graces baked into the WHERE:
+
+  (a) the investigation must have been terminal for at least
+      ``_ORPHAN_GRACE_SECONDS`` (5 min). Covers in-flight transitions that are
+      about to halt their own branches.
+  (b) the branch must not have been updated in the last
+      ``_BRANCH_TOUCH_GRACE_SECONDS`` (2 min). Covers a worker mid-LLM-call
+      whose commit is in flight.
+
+Generic over the module: the caller supplies its branch + investigation record
+models; this service never names a module. Each module binds the models via a
+module-level ``functools.partial`` so the registered sweep callable is a stable
+object (the periodic-sweep registry keys re-registration on callable identity).

Subject: [PATCH 185/281] refactor(services): lift multi_target to the platform
 (#29)

RFC-04 Phase 0 (fifth zero-delta support-service lift). The multi-target attach/list/detach service was duplicated verbatim in vr and malware. Move the logic to aila.platform.services.multi_target as MultiTargetServiceBase, generic over the investigation / target / attachment record models, the role enum, and the summary contract (bound as class variables). MultiTargetServiceError moves to the platform. Each module keeps a thin MultiTargetService subclass binding its concrete types; callers construct the same class name and the services barrel re-exports are unchanged, and MultiTargetServiceError stays catchable through the module path via re-export. Behavior-preserving: identical attach/list/detach logic and error conditions. Verified: compile/ruff/honesty clean, app imports, subclass wiring + error re-export identity, 52 vr+malware module tests pass.

Subject: [PATCH 186/281] refactor(services): lift pattern_store to the
 platform (#29)

RFC-04 Phase 0 (sixth zero-delta support-service lift). The pattern catalog storage + retrieval service was duplicated verbatim in vr and malware. Move the logic to aila.platform.services.pattern_store as PatternStoreBase, generic over the pattern record model, the module summary contract, and the KnowledgeEntryRecord namespace prefix (bound as class variables). PatternStoreError and PatternRetrievalResult move to the platform. Each module keeps a thin PatternStore subclass binding its types; callers construct the same class name, the services barrel re-exports are unchanged, and PatternStoreError / PatternRetrievalResult stay importable through the module path via re-export. The single-UoW pair-write (pattern INSERT + KnowledgeService mirror + entry_id back-link, with rollback when the mirror does not persist), the body-hash dedup key, the scope-widen guard, the mirror re-store on patch, and the two-stage applicable() retrieval with usage-counter update are all preserved. Verified: compile/ruff/honesty clean, app imports, subclass + error/result re-export identity, 156 coupled tests pass.

-"""Pattern catalog storage + retrieval service (Knowledge Transfer plan).
-
-Writes pairs of rows: the structured ``VRPatternRecord`` and a mirrored
-``KnowledgeEntryRecord`` (pgvector + FTS) so the pattern is retrievable
-by both structured filters (kind / applicability / scope) and semantic
-search.
-
-v1 ships:
-  - create()      -- insert pattern + mirror entry in one transaction
-  - get()         -- fetch single pattern
-  - list()        -- paginated + filterable
-  - patch()       -- operator review + scope promotion
-  - applicable()  -- structured-filter + semantic search retrieval
-
-Deferred to v1.1 (per GA-45/46):
-  - vr_pattern_usages success-rate tracking
-  - vr_pattern_chains cross-investigation links
-  - automatic re-rank by success_rate + recency

+"""Pattern catalog storage + retrieval service (Knowledge Transfer plan).
+
+Writes pairs of rows: the structured pattern record and a mirrored
+``KnowledgeEntryRecord`` (pgvector + FTS) so the pattern is retrievable
+by both structured filters (kind / applicability / scope) and semantic
+search.
+
+Generic over the module: a concrete subclass binds the pattern record
+model, the module summary contract, and the ``KnowledgeEntryRecord``
+namespace prefix as class variables. The platform base owns the
+create / get / list / patch / applicable logic and never names a module.
+
+v1 ships:
+  - create()      -- insert pattern + mirror entry in one transaction
+  - get()         -- fetch single pattern
+  - list()        -- paginated + filterable
+  - patch()       -- operator review + scope promotion
+  - applicable()  -- structured-filter + semantic search retrieval
+
+Deferred to v1.1 (per GA-45/46):
+  - <module>_pattern_usages success-rate tracking
+  - <module>_pattern_chains cross-investigation links
+  - automatic re-rank by success_rate + recency

Subject: [PATCH 187/281] refactor(services): lift stage_tracker to the
 platform (#29)

RFC-04 Phase 0 (seventh and final zero-delta support-service lift). The per-target analysis stage tracker was duplicated verbatim in vr and malware. Move the logic to aila.platform.services.stage_tracker: the exceptions (StageTrackerError / StageAlreadyDoneError / StageInFlightError) and parse_stages move outright; StageTracker becomes generic over the target record model via a class-var; load_target_stages / save_target_stages / reap_stuck_stages take the target model as a keyword argument. Each module keeps a thin stage_tracker that re-exports the exceptions + parse_stages, subclasses StageTracker binding its target model, and binds the model-coupled functions via module-level functools.partial -- which keeps reap_stuck_stages callable-identity stable for the periodic-sweep registry. Callers (module.py, _task_queue, target_analysis, function_ranker, profile_builder) are unchanged. The SELECT FOR UPDATE, RUNNING-timeout takeover, optimistic-concurrency UPDATE, and reaper logic are preserved verbatim. _DEFAULT_TIMEOUTS now lives in the platform module; the android-index test imports it from there. Verified: compile/ruff/honesty clean, app imports, sweep identity stable for both modules, 156 coupled tests pass.

-"""StageTracker -- durable per-stage status mutator for target analysis.
-
-Usage:
-
-    from aila.modules.malware.contracts.target_stages import StageName
-    from aila.modules.malware.services.stage_tracker import StageTracker, StageAlreadyDone
-
-    async def ingest_target(target_id: str):
-        try:
-            async with StageTracker(target_id, StageName.INGESTION,
-                                    stage_timeout_s=14400) as tracker:
-                handles = await do_actual_ingest(...)
-                await tracker.record_output(
-                    handles_json=json.dumps(handles),
-                    primary_language=lang,
-                )
-        except StageAlreadyDone:
-            # Stage was already DONE -- idempotent skip. Caller can
-            # safely return without redoing the work.
-            return
-        # On any other exception inside `async with`, the tracker
-        # automatically marks the stage FAILED with the exception
-        # message before the exception propagates upward.
-
-Semantics:
-
-  - Entering the context loads the target row, inspects the stage's
-    current status, and:
-      * DONE      → raises StageAlreadyDone (caller decides to skip)
-      * RUNNING within stage_timeout_s → raises StageInFlight
-      * RUNNING past stage_timeout_s   → resets to RUNNING with new
-        started_at + incremented attempts (operator-resume / reaper)
-      * PENDING / FAILED → transitions to RUNNING with attempts+1
-
-  - Exiting normally → state=DONE, completed_at=now, error=None.
-  - Exiting via exception → state=FAILED, error=type(exc).__name__:
-    str(exc), completed_at=now. Exception re-propagates.
-
-  - Every commit also recomputes and writes the rolled-up
-    `analysis_state` enum so legacy consumers (UI fields, queries)
-    keep working without refactor.
-
-  - Optional `record_output(**columns)` lets the caller persist
-    work-product columns (mcp_handles_json, capability_profile_json,
-    function_ranking, primary_language) inside the same transaction
-    that flips the stage to DONE. Without this, partial work could
-    be lost if the worker dies between writing the output and
-    flipping the stage.
+"""Malware binding of the platform per-target stage tracker service.
+
+Binds the platform generic :class:`StageTracker` and its module-level helpers
+to the malware :class:`MalwareTargetRecord`. The model-coupled functions are
+wrapped as module-level ``functools.partial`` so the registered periodic-sweep
+callable (``reap_stuck_stages``) is a stable object across re-imports -- the
+sweep registry keys re-registration on callable identity, and an inline partial
+at the registration site would break the re-registration no-op.

-"""StageTracker -- durable per-stage status mutator for target analysis.
-
-Usage:
-
-    from aila.modules.vr.contracts.target_stages import StageName
-    from aila.modules.vr.services.stage_tracker import StageTracker, StageAlreadyDone
-
-    async def ingest_target(target_id: str):
-        try:
-            async with StageTracker(target_id, StageName.INGESTION,
-                                    stage_timeout_s=14400) as tracker:
-                handles = await do_actual_ingest(...)
-                await tracker.record_output(
-                    handles_json=json.dumps(handles),
-                    primary_language=lang,
-                )
-        except StageAlreadyDone:
-            # Stage was already DONE -- idempotent skip. Caller can
-            # safely return without redoing the work.
-            return
-        # On any other exception inside `async with`, the tracker
-        # automatically marks the stage FAILED with the exception
-        # message before the exception propagates upward.
-
-Semantics:
-
-  - Entering the context loads the target row, inspects the stage's
-    current status, and:
-      * DONE      → raises StageAlreadyDone (caller decides to skip)
-      * RUNNING within stage_timeout_s → raises StageInFlight
-      * RUNNING past stage_timeout_s   → resets to RUNNING with new
-        started_at + incremented attempts (operator-resume / reaper)
-      * PENDING / FAILED → transitions to RUNNING with attempts+1
-
-  - Exiting normally → state=DONE, completed_at=now, error=None.
-  - Exiting via exception → state=FAILED, error=type(exc).__name__:
-    str(exc), completed_at=now. Exception re-propagates.
-
-  - Every commit also recomputes and writes the rolled-up
-    `analysis_state` enum so legacy consumers (UI fields, queries)
-    keep working without refactor.
-
-  - Optional `record_output(**columns)` lets the caller persist
-    work-product columns (mcp_handles_json, capability_profile_json,
-    function_ranking, primary_language) inside the same transaction
-    that flips the stage to DONE. Without this, partial work could
-    be lost if the worker dies between writing the output and
-    flipping the stage.
+"""VR binding of the platform per-target stage tracker service.
+
+Binds the platform generic :class:`StageTracker` and its module-level helpers
+to the VR :class:`VRTargetRecord`. The model-coupled functions are wrapped as
+module-level ``functools.partial`` so the registered periodic-sweep callable
+(``reap_stuck_stages``) is a stable object across re-imports -- the sweep
+registry keys re-registration on callable identity, and an inline partial at
+the registration site would break the re-registration no-op.

+"""StageTracker -- durable per-stage status mutator for target analysis.
+
+Generic over the module: concrete subclasses bind the target record model
+as a class variable, and module-level ``functools.partial`` wrappers bind
+the model to the module-level helpers. The platform base owns the
+idempotency / RUNNING-timeout / SELECT-FOR-UPDATE / optimistic-concurrency
+logic and never names a module.
+
+Usage (from a module binding):
+
+    from aila.platform.contracts.target_stages import StageName
+    from aila.modules.vr.services.stage_tracker import (
+        StageTracker, StageAlreadyDoneError,
+    )
+
+    async def ingest_target(target_id: str):
+        try:
+            async with StageTracker(target_id, StageName.INGESTION,
+                                    stage_timeout_s=14400) as tracker:
+                handles = await do_actual_ingest(...)
+                await tracker.record_output(
+                    handles_json=json.dumps(handles),
+                    primary_language=lang,
+                )
+        except StageAlreadyDoneError:
+            # Stage was already DONE -- idempotent skip. Caller can
+            # safely return without redoing the work.
+            return
+        # On any other exception inside `async with`, the tracker
+        # automatically marks the stage FAILED with the exception
+        # message before the exception propagates upward.
+
+Semantics:
+
+  - Entering the context loads the target row, inspects the stage's
+    current status, and:
+      * DONE      -> raises StageAlreadyDoneError (caller decides to skip)
+      * RUNNING within stage_timeout_s -> raises StageInFlightError
+      * RUNNING past stage_timeout_s   -> resets to RUNNING with new
+        started_at + incremented attempts (operator-resume / reaper)
+      * PENDING / FAILED -> transitions to RUNNING with attempts+1
+
+  - Exiting normally -> state=DONE, completed_at=now, error=None.
+  - Exiting via exception -> state=FAILED, error=type(exc).__name__:
+    str(exc), completed_at=now. Exception re-propagates.
+
+  - Every commit also recomputes and writes the rolled-up
+    ``analysis_state`` enum so legacy consumers (UI fields, queries)
+    keep working without refactor.
+
+  - Optional ``record_output(**columns)`` lets the caller persist
+    work-product columns (mcp_handles_json, capability_profile_json,
+    function_ranking, primary_language) inside the same transaction
+    that flips the stage to DONE. Without this, partial work could
+    be lost if the worker dies between writing the output and
+    flipping the stage.

Subject: [PATCH 188/281] refactor(mcp): lift mcp_registry to the platform
 (#29)

RFC-04 Phase 1 (pure-parameterization lift). The MCP registry probe/resolve/update service was near-identical across vr and malware, differing only in the MCP_SERVERS catalog and the ConfigRegistry namespace. Move it to aila.platform.mcp.registry.McpRegistryServiceBase generic over _module_id + _servers class-vars; each module keeps its MCP_SERVERS catalog verbatim and a thin McpRegistryService subclass binding them. Callers and barrel re-exports unchanged. probe_all's do_nothing_wrapper whitelist entry moves from the two module paths to the platform base. Behavior-preserving. Verified: compile/ruff/honesty clean, app imports, catalog + namespace bindings, 111 coupled tests pass.

-"""McpRegistryService -- operator-facing MCP servers health + config surface.
+"""Malware binding of the platform McpRegistryServiceBase.
 
-AILA is orchestration only (D-33). Every analytical action is delegated
-to an MCP server running on a workstation. This service surfaces:
+Owns the malware-side ``MCP_SERVERS`` catalog and binds it (with the
+``"malware"`` ConfigRegistry namespace) onto the platform base. The
+platform base owns the resolve / probe / update logic; this module is
+module residue only.
 
-* which MCP servers the platform knows about (audit-mcp, ida-headless)
-* the URL each one currently resolves to (env → ConfigRegistry → default)
-* a live HTTP health probe (reachable / unreachable + latency)
-* the tool count and tool names each server advertises
-* a write path so the operator can retarget a server at a different
-  workstation without touching env vars
-
-The result projection deliberately uses operator vocabulary -- no
-``mcp_handles_json``, no internal task ids. Just `id`, `name`,
-`description`, `base_url`, `status`, `latency_ms`, `tool_count`,
-`tools`, `last_probed_at`, and `error` when unreachable.
+To add a new MCP, append here AND add a matching field to
+``MalwareConfigSchema``. The operator-facing UI auto-discovers the list
+of servers from this catalog at request time.

Subject: [PATCH 189/281] refactor(services): lift stall_recovery to the
 platform (#29)

RFC-04 Phase 1 (pure-parameterization lift). The stalled-investigation recovery sweep was near-identical across vr and malware. Move the sweep logic to aila.platform.services.stall_recovery parameterized over sweepable_kinds, single_submit_kinds, env_prefix, the two table names, and an injected submit_fn. Each module keeps its own _default_submit_fn (vr routes n_day to run_vr_nday with the single-inv-submit path; malware routes all kinds to run_malware_investigate) and binds sweep_stalled_investigations via a module-level functools.partial so the periodic-sweep callable identity stays stable. module.py registrations unchanged. Behavior-preserving including vr's n_day dispatch. Verified: compile/ruff/honesty clean, sweep identity stable both modules, 111 coupled tests pass.

-"""Periodic sweep that re-enqueues stalled malware investigations.
-
-When a malware task gets killed mid-execution -- ``CancelledError`` from
-ARQ's ``max_job_time``, worker process restart, host kernel kill -- no
-exception handler runs, no cursor is written, no ``AUTO_CONTINUE``
-fires. The investigation row stays at ``status='running'`` (or
-``status='created'`` if the very first enqueue was lost) with branches
-in ``status='active'`` forever, with zero in-flight tasks pointing at
-it.
-
-The cutover Phase B / C / engine fixes all assume the task body either
-returns or raises through a normal ``Exception`` path. None handle
-``CancelledError``, which inherits from ``BaseException`` (not
-``Exception``) and is therefore not caught by the ``except Exception``
-handlers around AUTO_CONTINUE. This sweep is the recovery backstop.
-
-Companion to ``cursor_reaper.sweep_orphan_crashed_cursors`` (which
-deletes orphan terminal cursors). That helper handles cleanup; this
-one handles recovery.
-
-Eligibility (every clause MUST hold):
-
-* ``inv.status IN ('created', 'running')`` -- only non-terminal
-  investigations can recover.
-* ``inv.pause_reason IS NULL`` -- operator and self-paused
-  investigations (``operator`` / ``low_confidence`` / ``cost_budget``
-  / ``awaiting_campaign`` / ``awaiting_mcp``) are intentional waits
-  and MUST NOT be auto-resumed by this sweep. M3.R-6 resumer owns
-  the auto-resume cases; operator owns the operator case.
-* ``inv.updated_at < NOW() - <idle threshold>`` -- slow turns
-  (8-minute semantic searches, long reasoning) MUST not be double-
-  fired. The threshold distinguishes "legitimately slow" from
-  "really stalled".
-* **No in-flight task** references this investigation. A row in
-  ``taskrecord`` with status ``queued`` / ``running`` / ``waiting``
-  whose ``kwargs_json::jsonb->>'investigation_id'`` equals this
-  ``inv.id`` blocks re-enqueue. The worker's ``reaper.stale_in_
-  progress_reconciled`` sweep will eventually flip dead-worker
-  tasks to ``cancelled``; the next sweep tick after that picks
-  them up.
-
-Re-enqueue dispatch table:
-
-* every sweepable malware kind (``full_analysis`` / ``triage`` /
-  ``unpack_only`` / ``config_extract`` / ``yara_generate`` /
-  ``family_attribute``) submits ``run_malware_investigate``. If the
-  inv has any ``status='active'`` branches, fan out one submit
-  per active branch with ``branch_id`` set. If no active branches
-  exist (typically ``status='created'`` invs that never spawned),
-  submit once with only ``investigation_id``; the
-  ``investigation_setup`` state will spawn branches on first turn.
-
-Rate model:
-
-``rate_per_tick`` caps **total task submits** in one sweep call --
-NOT investigation count. The unit matters: one investigation with 6
-active personas produces 6 submits, six 1-branch investigations also
-produce 6. The cap is what bounds the downstream LLM request rate.
-
-Default 6. Rationale: with ~4 malware workers and the LLM client doing
-~1 request per turn, the steady-state LLM rate is roughly
-``min(workers, submits-per-min) × calls-per-turn``. A burst of 6
-new submits per tick keeps the sweep contribution comfortably under
-NVIDIA NIM's 40 RPM free-tier ceiling, leaving headroom for non-
-sweep traffic (operator-triggered new investigations, finalize and
-synthesis tasks, etc.).
-
-Operator tunes via env vars:
+"""Malware binding of the platform stall-recovery sweep.
+
+Binds the platform generic to malware's investigations + branches tables,
+the malware sweepable-kind set (every ``InvestigationKind`` value; there
+is no parent-batch flow like VR's ``masvs_audit`` to exclude), the
+malware env-var prefix, and the malware task submitter.
+
+Unlike VR, malware v1 ships no kind whose task body owns its own branch
+lifecycle -- there is no ``n_day`` equivalent -- so
+``_SINGLE_SUBMIT_KINDS`` is empty. Every eligible malware row goes
+through the standard "fan out per active branch or single inv-level
+submit if no branches" path.
+
+``_default_submit_fn`` stays module-side because it imports the malware-
+owned task function (``run_malware_investigate``). The imports are
+deferred so the sweep module can be imported from the worker boot path
+without pulling the module loader / task queue surface.
+``api_router.py``'s operator ``/re-enqueue`` handler re-uses this
+submitter directly for the same rate-limited submit path the periodic
+sweep uses.
+
+``sweep_stalled_investigations`` is a module-level ``functools.partial``
+so the periodic-sweep registry (which keys re-registration on callable
+identity) sees a stable object across re-imports -- mirrors the pattern
+in ``branch_reaper.py``.
+
+Rate model, eligibility semantics, and the recovery rationale are
+documented on the platform sweep -- see
+``aila.platform.services.stall_recovery``.
+
+Env-var knobs (operator-tunable, unchanged from pre-lift):
 
 * ``AILA_MALWARE_STALL_RECOVERY_LIMIT`` -- submits per tick (default 6)
 * ``AILA_MALWARE_STALL_RECOVERY_IDLE_MIN`` -- idle threshold in minutes
   (default 15)
-
-``bypass_dedup=True`` on every submit so a stale running-status
-``TaskRecord`` from a dead worker doesn't block the §72 partial
-unique-hash index that would otherwise short-circuit recovery.
-
-No re-enqueue counter cap by design: investigations
-that keep stalling SHOULD keep getting re-enqueued. If an
-investigation is permanently broken (e.g. infinite parse-failure
-loop on a single turn), it will eventually accumulate enough
-``status='failed'`` TaskRecord rows that the operator notices in
-the worker log volume and intervenes.

-"""Periodic sweep that re-enqueues stalled VR investigations.
+"""VR binding of the platform stall-recovery sweep.
 
-When a VR task gets killed mid-execution -- ``CancelledError`` from
-ARQ's ``max_job_time``, worker process restart, host kernel kill -- no
-exception handler runs, no cursor is written, no ``AUTO_CONTINUE``
-fires. The investigation row stays at ``status='running'`` (or
-``status='created'`` if the very first enqueue was lost) with branches
-in ``status='active'`` forever, with zero in-flight tasks pointing at
-it.
+Binds the platform generic to VR's investigations + branches tables, the
+VR sweepable-kind set (with ``n_day`` marked as a single-submit kind so
+the sweep skips branch fan-out for it), the VR env-var prefix, and the
+VR task submitter.
 
-The cutover Phase B / C / engine fixes all assume the task body either
-returns or raises through a normal ``Exception`` path. None handle
-``CancelledError``, which inherits from ``BaseException`` (not
-``Exception``) and is therefore not caught by the ``except Exception``
-handlers around AUTO_CONTINUE. This sweep is the recovery backstop.
+``_default_submit_fn`` stays module-side because it imports the VR-owned
+task functions (``run_vr_investigate`` + ``run_vr_nday``) with the
+``n_day`` dispatch branch. The imports are deferred so the sweep module
+can be imported from the worker boot path without pulling the module
+loader / task queue surface.
 
-Companion to ``cursor_reaper.sweep_orphan_crashed_cursors`` (which
-deletes orphan terminal cursors). That helper handles cleanup; this
-one handles recovery.
+``sweep_stalled_investigations`` is a module-level ``functools.partial``
+so the periodic-sweep registry (which keys re-registration on callable
+identity) sees a stable object across re-imports -- mirrors the pattern
+in ``branch_reaper.py``.
 
-Eligibility (every clause MUST hold):
+Rate model, eligibility semantics, and the recovery rationale are
+documented on the platform sweep -- see
+``aila.platform.services.stall_recovery``.
 
-* ``inv.status IN ('created', 'running')`` -- only non-terminal
-  investigations can recover.
-* ``inv.pause_reason IS NULL`` -- operator and self-paused
-  investigations (``operator`` / ``low_confidence`` / ``cost_budget``
-  / ``awaiting_campaign`` / ``awaiting_mcp``) are intentional waits
-  and MUST NOT be auto-resumed by this sweep. M3.R-6 resumer owns
-  the auto-resume cases; operator owns the operator case.
-* ``inv.kind != 'masvs_audit'`` -- the MASVS parent's lifecycle is
-  owned by ``parent_reconciler``. The parent's child investigations
-  are regular ``audit`` kind and ARE eligible.
-* ``inv.updated_at < NOW() - <idle threshold>`` -- slow turns
-  (8-minute semantic searches, long reasoning) MUST not be double-
-  fired. The threshold distinguishes "legitimately slow" from
-  "really stalled".
-* **No in-flight task** references this investigation. A row in
-  ``taskrecord`` with status ``queued`` / ``running`` / ``waiting``
-  whose ``kwargs_json::jsonb->>'investigation_id'`` equals this
-  ``inv.id`` blocks re-enqueue. The worker's ``reaper.stale_in_
-  progress_reconciled`` sweep will eventually flip dead-worker
-  tasks to ``cancelled``; the next sweep tick after that picks
-  them up.
-
-Re-enqueue dispatch table:
-
-* ``n_day`` → ``run_vr_nday(investigation_id=...)``. Single submit
-  per inv; the nday task body manages its own internal branching.
-* all other sweepable kinds (``audit`` / ``discovery`` /
-  ``variant_hunt`` / ``triage``) → ``run_vr_investigate``. If the
-  inv has any ``status='active'`` branches, fan out one submit
-  per active branch with ``branch_id`` set. If no active branches
-  exist (typically ``status='created'`` invs that never spawned),
-  submit once with only ``investigation_id`` -- the
-  ``investigation_setup`` state will spawn branches on first turn.
-
-Rate model:
-
-``rate_per_tick`` caps **total task submits** in one sweep call --
-NOT investigation count. The unit matters: one investigation with 6
-active personas produces 6 submits, six 1-branch investigations also
-produce 6. The cap is what bounds the downstream LLM request rate.
-
-Default 6. Rationale: with ~4 vr workers and the LLM client doing
-~1 request per turn, the steady-state LLM rate is roughly
-``min(workers, submits-per-min) × calls-per-turn``. A burst of 6
-new submits per tick keeps the sweep contribution comfortably under
-NVIDIA NIM's 40 RPM free-tier ceiling, leaving headroom for non-
-sweep traffic (operator-triggered new investigations, finalize and
-synthesis tasks, etc.).
-
-Operator tunes via env vars:
+Env-var knobs (operator-tunable, unchanged from pre-lift):
 
 * ``AILA_VR_STALL_RECOVERY_LIMIT`` -- submits per tick (default 6)
 * ``AILA_VR_STALL_RECOVERY_IDLE_MIN`` -- idle threshold in minutes
   (default 15)
-
-``bypass_dedup=True`` on every submit so a stale running-status
-``TaskRecord`` from a dead worker doesn't block the §72 partial
-unique-hash index that would otherwise short-circuit recovery.
-
-No re-enqueue counter cap by design: investigations
-that keep stalling SHOULD keep getting re-enqueued. If an
-investigation is permanently broken (e.g. infinite parse-failure
-loop on a single turn), it will eventually accumulate enough
-``status='failed'`` TaskRecord rows that the operator notices in
-the worker log volume and intervenes.

+"""Generic periodic sweep that re-enqueues stalled investigations.
+
+Module bindings supply the eligibility SQL identifiers (table names for the
+investigations + branches), the sweepable-kind set, the env-var prefix that
+tunes rate/idle threshold, and the concrete submitter that knows how to
+enqueue a task for that module. See ``branch_reaper`` for the same pattern
+applied to the orphan-branch reaper: each module wraps this callable via a
+module-level ``functools.partial`` so the callable identity is stable across
+imports (the periodic-sweep registry keys re-registration on identity, so an
+inline partial at the registration site would break the re-registration
+no-op).
+
+Context (unchanged from the pre-lift module docstrings):
+
+When a task gets killed mid-execution -- ``CancelledError`` from ARQ's
+``max_job_time``, worker process restart, host kernel kill -- no exception
+handler runs, no cursor is written, no ``AUTO_CONTINUE`` fires. The
+investigation row stays at ``status='running'`` (or ``status='created'`` if
+the very first enqueue was lost) with branches in ``status='active'``
+forever, with zero in-flight tasks pointing at it. Every other cutover fix
+assumes the task body returns or raises through ``Exception``; sequence
+of ``CancelledError`` (inherits from ``BaseException``, escapes broad
+``except Exception`` handlers) is the recovery gap this sweep closes.
+
+Eligibility (every clause MUST hold):
+
+* ``inv.status IN ('created', 'running')`` -- only non-terminal
+  investigations can recover.
+* ``inv.pause_reason IS NULL`` -- operator and self-paused investigations
+  are intentional waits and MUST NOT be auto-resumed by this sweep.
+* ``inv.kind = ANY(:kinds)`` -- only sweepable kinds are handled. Callers
+  exclude parent-batch kinds whose lifecycle is owned by another
+  reconciler (VR's ``masvs_audit`` is the current example).
+* ``inv.updated_at < NOW() - <idle threshold>`` -- distinguishes
+  "legitimately slow" from "really stalled".
+* **No in-flight task** references this investigation. A row in
+  ``taskrecord`` with status ``queued`` / ``running`` / ``waiting`` whose
+  ``kwargs_json::jsonb->>'investigation_id'`` equals this ``inv.id``
+  blocks re-enqueue. The worker's stale-in-progress reaper will
+  eventually flip dead-worker tasks to ``cancelled``; the next sweep
+  tick after that picks them up.
+
+Re-enqueue dispatch:
+
+* ``inv.kind`` in ``single_submit_kinds`` -> single inv-level submit,
+  no branch fan-out. Used by module kinds that own their own branch
+  lifecycle internally (VR's ``n_day``); the caller's submitter routes
+  these to the appropriate task function.
+* everything else -> if the inv has ``status='active'`` branches, fan
+  out one submit per branch with ``branch_id`` set; otherwise submit
+  once with only ``investigation_id`` (``investigation_setup`` will
+  spawn branches on first turn).
+
+Rate model:
+
+``rate_per_tick`` caps **total task submits** in one sweep call -- NOT
+investigation count. The unit matters: one investigation with 6 active
+personas produces 6 submits; six 1-branch investigations also produce 6.
+The cap is what bounds the downstream LLM request rate. Default 6.
+
+Operator tunes via env vars derived from ``env_prefix``:
+
+* ``<PREFIX>_LIMIT`` -- submits per tick (default 6)
+* ``<PREFIX>_IDLE_MIN`` -- idle threshold in minutes (default 15)
+
+The raw SQL uses ``sqlalchemy.text`` and interpolates the bound table
+names -- table identifiers cannot be bind parameters, and the identifiers
+are trusted module constants defined at import time in each module's
+binding file, never operator or request input.

Subject: [PATCH 190/281] refactor(services): lift outcome_review to the
 platform (#29)

RFC-04 Phase 1 (pure-parameterization lift). The sibling vote/quorum review kernel was near-identical across vr and malware; malware additionally carries VETO_K=2 and a ~260-line edit_outcome feature vr lacks. Move the kernel + edit_outcome to aila.platform.services.outcome_review generic over the four record models, veto_k, and audit_stage. The veto-reason wire format derives from veto_k so each module reproduces its exact string (vr vetoed_by_N_sibling(s); malware appends _veto_k=2). Each module keeps thin functools.partial bindings + constant re-exports: vr binds veto_k=1 and does not expose edit_outcome; malware binds veto_k=2 and exposes edit_outcome. Callers and __all__ surfaces unchanged. F401 per-file-ignore added for the two re-export bindings. Behavior-preserving: vr vetoes at reject>=1, malware at reject>=2. Verified: compile/ruff/honesty clean, threshold + reason-format + edit_outcome bindings, 111 coupled tests pass.

-
-Quorum threshold ``QUORUM_K`` = ``max(2, ceil(non_proposing_siblings/2))``.
-For a typical 6-branch investigation: 5 non-proposing siblings -> K=5.
-For a 3-branch investigation: 2 non-proposing -> K=2. For a single-
-branch investigation (no siblings): K=0 means the outcome auto-approves
-on creation (no one to review, gate is a no-op).
-
-Veto threshold ``VETO_K`` = 2. A reject vote is advisory until a SECOND
-sibling concurs -- one bad sibling reading off a stale or buggy tool
-result should not kill an otherwise-correct outcome. The threshold was
-1 historically; an observed bug let a single sibling reject built
-on a tool-bug false-negative (encoding-filter round-trip bug, fixed in
-an earlier bridge + ida-headless fix) veto a correct ANALYSIS_REPORT
-on one observed investigation (Stage 1 + Stage 2 RAT config both
-surfaced; final tally approve=2 reject=1 abstain=0 -- two siblings
-agreed the report was right, one called it wrong on broken data,
-hard-veto rule killed it anyway). Raising to 2 keeps the veto as a
-kill switch but requires the kill to be a chorus, not a solo. Single
-rejects are still recorded on
-the outcome (operator can audit reject_count) and the proposing branch
-still sees the reject vote in its prompt so it can react -- the
-threshold change ONLY affects when the state flip fires.
-
-In addition to voting, agents can call the ``edit_outcome`` action to
-directly merge patches into a draft outcome's ``payload_json`` (see
-:func:`edit_outcome`). Direct edit is gated to ``state='draft'``;
-edits on approved / rejected / dispatched rows fail closed so the
-dispatched artifact stays the source of truth for downstream
-consumers. This is the IMMEDIATE-merge counterpart to the existing
-``request_edit`` vote (which only suggests edits the synthesis agent
-picks up on the next pass).
-
-This module is the single source of truth for:
-  * vote upsert (one row per branch per outcome)
-  * quorum evaluation (approve quorum) + veto evaluation (reject quorum)
-  * direct edit of draft payload (any active branch on the investigation)
-  * state transition (draft -> approved | rejected)
-  * sibling halt on approved
-  * downstream dispatch trigger on approved
+"""Malware binding of the platform draft outcome review service.
+
+Binds the platform generic vote/quorum kernel to the malware record models via
+module-level ``functools.partial``. The exported callables retain stable
+identity across re-imports and preserve the module's historical public surface:
+
+* the four ``OUTCOME_STATE_*`` constants + the four ``VOTE_*`` constants,
+* :data:`VETO_K` = 2 (the module-observed threshold; see comment below),
+* :func:`compute_quorum` (pure, no model dependency),
+* :func:`set_outcome_state`, :func:`upsert_review`, :func:`evaluate_quorum`,
+  :func:`post_draft_review_request` -- pre-bound to
+  :class:`MalwareInvestigationOutcomeRecord`,
+  :class:`MalwareInvestigationBranchRecord`,
+  :class:`MalwareInvestigationOutcomeReviewRecord`,
+  :class:`MalwareInvestigationMessageRecord`, and to malware's ``veto_k=2``
+  + ``audit_stage="malware.outcome"``,
+* :func:`edit_outcome` -- direct-merge counterpart to the deferred
+  ``request_edit`` vote, pre-bound to the malware outcome + branch models.

+See :mod:`aila.platform.services.outcome_review` for the generic kernel and
+the full lifecycle documentation.

-
-    ``suggested_edits_json`` contract (fix §170)
-    --------------------------------------------
-    When ``vote == 'request_edit'`` the agent may attach a
-    ``suggested_edits`` payload (e.g. ``{"confidence": "weak"}``,
-    ``{"answer": "corrected text"}``). That payload is persisted on the
-    review row as ``suggested_edits_json`` and is **consumed by the
-    synthesis agent** when it merges per-persona panel contributions
-    into the canonical outcome. See :class:`aila.modules.malware.agents.
-    synthesis_agent.SynthesisAgent.run` -- that is the ONE place
-    suggested edits get folded back into the canonical narrative.
-
-    Structured per-row semantics for downstream readers:
-
-    - ``suggested_edits_json``      stored as JSON (this function).
-    - ``applied_by_synthesis: bool`` IMPLICIT contract -- there is no
-      column for it; the synthesis agent's panel-merge step is the
-      sole consumer and operates idempotently (its ``panel_summary``
-      marker on the canonical outcome means the merge has incorporated
-      every review row visible at synthesis time). A future ``applied_at``
-      column on the review row would let the synthesis agent record
-      provenance per suggestion, but the current contract is "all
-      review rows belonging to the canonical outcome MUST be reread
-      on every synthesis run" -- no per-row applied bit required.
-
-    DESIGN (fix §170): chose option (b) from prior design notes §4 --
-    synthesis-agent consumption rather than a frontend Apply button.
-    Rationale: (a) needs a frontend project + operator-gated API + a
-    second write path on the canonical outcome; (b) reuses the
-    existing synthesis chokepoint that ALREADY merges per-persona
-    contributions, runs without operator clicks, and folds the
-    correction into the same panel_summary the operator already reads.
-    The two-path version (a)+(b) was rejected as a duplicate-write
-    risk against Golden Rule #19 (don't repeat yourself).

-
-Quorum threshold ``QUORUM_K`` = ``max(2, ceil(non_proposing_siblings/2))``.
-For a typical 6-branch investigation: 5 non-proposing siblings -> K=3.
-For a 3-branch investigation: 2 non-proposing -> K=2. For a single-
-branch investigation (no siblings): K=0 means the outcome auto-approves
-on creation (no one to review, gate is a no-op).
-
-Reject is a hard veto: a single reject flips the outcome to ``rejected``
-and the gate refuses dispatch. The proposing branch can resume reasoning
-and submit a new outcome, which is a fresh row (DRAFT again). The
-rejected row is preserved as audit trail.
-
-This module is the single source of truth for:
-  * vote upsert (one row per branch per outcome)
-  * quorum evaluation
-  * state transition (draft -> approved | rejected)
-  * sibling halt on approved
-  * downstream dispatch trigger on approved
+"""VR binding of the platform draft outcome review service.
+
+Binds the platform generic vote/quorum kernel to the VR record models via
+module-level ``functools.partial``. The exported callables retain stable
+identity across re-imports and preserve the module's historical public surface:
+
+* the four ``OUTCOME_STATE_*`` constants + the four ``VOTE_*`` constants,
+* :func:`compute_quorum` (pure, no model dependency),
+* :func:`set_outcome_state`, :func:`upsert_review`, :func:`evaluate_quorum`,
+  :func:`post_draft_review_request` -- all pre-bound to
+  :class:`VRInvestigationOutcomeRecord`, :class:`VRInvestigationBranchRecord`,
+  :class:`VRInvestigationOutcomeReviewRecord`,
+  :class:`VRInvestigationMessageRecord`, and to VR's historical
+  ``veto_k=1`` (single reject vetoes) + ``audit_stage="vr.outcome"``.
+
+VR does not expose the direct ``edit_outcome`` action; the malware module's
+binding does. See :mod:`aila.platform.services.outcome_review` for the
+generic kernel and the full lifecycle documentation.

-      marker on the canonical outcome means the merge has incorporated
-      every review row visible at synthesis time). A future ``applied_at``
-      column on the review row would let the synthesis agent record
-      provenance per suggestion, but the current contract is "all
-      review rows belonging to the canonical outcome MUST be reread
-      on every synthesis run" -- no per-row applied bit required.
-
-    DESIGN (fix §170): chose option (b) from prior design notes §4 --
-    synthesis-agent consumption rather than a frontend Apply button.
-    Rationale: (a) needs a frontend project + operator-gated API + a
-    second write path on the canonical outcome; (b) reuses the
-    existing synthesis chokepoint that ALREADY merges per-persona
-    contributions, runs without operator clicks, and folds the
-    correction into the same panel_summary the operator already reads.
-    The two-path version (a)+(b) was rejected as a duplicate-write

+   >= QUORUM_K     >= VETO_K

+  dispatcher fires   branches resume;
+       |             outcome stays as
+       v             permanent record
+  state='dispatched'
+
+Quorum threshold ``QUORUM_K`` = ``max(2, ceil(non_proposing_siblings/2))``.
+For a typical 6-branch investigation: 5 non-proposing siblings -> K=5.
+For a 3-branch investigation: 2 non-proposing -> K=2. For a single-
+branch investigation (no siblings): K=0 means the outcome auto-approves
+on creation (no one to review, gate is a no-op).
+
+Veto threshold ``VETO_K`` is caller-supplied (kwarg). VR historically used
+``veto_k=1`` (a single reject vetoes the whole outcome). Malware raised
+its veto_k to 2 after an observed bug let correct ANALYSIS_REPORTs be
+killed by a lone sibling reject built on a tool-bug false-negative --
+raising to 2 keeps the veto as a kill switch but requires the kill to
+be a chorus, not a solo. Rejects below the threshold are still recorded
+(the proposing branch sees them and can react / edit) but do not
+trigger the state flip.
+
+In addition to voting, agents can call :func:`edit_outcome` to directly
+merge patches into a draft outcome's ``payload_json``. Direct edit is
+gated to ``state='draft'``; edits on approved / rejected / dispatched
+rows fail closed so the dispatched artifact stays the source of truth
+for downstream consumers. This is the IMMEDIATE-merge counterpart to
+the existing ``request_edit`` vote (which only suggests edits the
+synthesis agent picks up on the next pass).
+
+Generic over the module: every model-coupled function takes the record
+models as keyword parameters. Each module binds those parameters via
+module-level ``functools.partial`` so the exported callables carry
+stable identity and the module's call sites stay unchanged.
+
+This module is the single source of truth for:
+  * vote upsert (one row per branch per outcome)
+  * quorum evaluation (approve quorum) + veto evaluation (reject quorum)
+  * direct edit of draft payload (any active branch on the investigation)
+  * state transition (draft -> approved | rejected)
+  * sibling halt on approved
+  * downstream dispatch trigger on approved

+
+    ``suggested_edits_json`` contract (fix §170)
+    --------------------------------------------
+    When ``vote == 'request_edit'`` the agent may attach a
+    ``suggested_edits`` payload (e.g. ``{"confidence": "weak"}``,
+    ``{"answer": "corrected text"}``). That payload is persisted on the
+    review row as ``suggested_edits_json`` and is **consumed by the
+    synthesis agent** when it merges per-persona panel contributions
+    into the canonical outcome. See the module's ``SynthesisAgent.run``
+    -- that is the ONE place suggested edits get folded back into the
+    canonical narrative.
+
+    Structured per-row semantics for downstream readers:
+
+    - ``suggested_edits_json``      stored as JSON (this function).
+    - ``applied_by_synthesis: bool`` IMPLICIT contract -- there is no
+      column for it; the synthesis agent's panel-merge step is the
+      sole consumer and operates idempotently (its ``panel_summary``
+      marker on the canonical outcome means the merge has incorporated
+      every review row visible at synthesis time). A future ``applied_at``
+      column on the review row would let the synthesis agent record
+      provenance per suggestion, but the current contract is "all
+      review rows belonging to the canonical outcome MUST be reread
+      on every synthesis run" -- no per-row applied bit required.
+
+    DESIGN (fix §170): chose option (b) from prior design notes §4 --
+    synthesis-agent consumption rather than a frontend Apply button.
+    Rationale: (a) needs a frontend project + operator-gated API + a
+    second write path on the canonical outcome; (b) reuses the
+    existing synthesis chokepoint that ALREADY merges per-persona
+    contributions, runs without operator clicks, and folds the
+    correction into the same panel_summary the operator already reads.
+    The two-path version (a)+(b) was rejected as a duplicate-write
+    risk against Golden Rule #19 (don't repeat yourself).

Subject: [PATCH 191/281] fix(mcp): unify MCP call logger; malware gains
 correlation join-keys (#29 #39)

RFC-04 Phase 1 adopt-fix. The MCP call logger was near-identical across vr and malware but carried two drifts: (1) vr stamped the #39 correlation join-keys while malware did not (malware MCP call-log rows could not be joined to the investigation/branch/turn that made them), and (2) vr swallowed all exceptions via contextlib.suppress(Exception) while malware caught a typed set. This lifts the logger to aila.platform.mcp.call_logger generic over the record model and closes both drifts by construction:

- The three join-keys are hoisted from the vr-only residue onto McpCallLogRecordBase, so both VRMcpCallLogRecord and MalwareMcpCallLogRecord carry them. Migration 085 adds the columns + indexes to malware_mcp_call_log (vr already had them from 082). BEHAVIOR CHANGE: malware MCP call logs are now correlated.

- The platform logger stamps the join-keys unconditionally and uses the typed-exception set (SQLAlchemyError/OSError/RuntimeError/TimeoutError). BEHAVIOR CHANGE: a schema bug in the vr call-log write now surfaces instead of being silently swallowed.

Each module keeps a thin record_call functools.partial binding its record model; callers unchanged. Verified: compile/ruff/honesty clean, both models carry the join-keys, vr + malware correlation tests pass, 63 module/contract tests pass. Requires migration 085 + operator end-to-end smoke on a running investigation per the adopt-fix decision.

+"""085 -- add #39 observability join-keys to malware_mcp_call_log (#29 / #39).

+RFC-04 Phase 1 unified the MCP call logger across vr and malware. The three
+observability join-keys (investigation_id / branch_id / turn_number) were on
+vr_mcp_call_log only (migration 082); this migration adds them to
+malware_mcp_call_log so a malware MCP call-log row can be joined back to the

+platform/contracts/mcp_call_log_base.py.

+Guarded with IF NOT EXISTS so a re-run, or a fresh database that already

Subject: [PATCH 192/281] refactor(services): lift investigation cap reaper to
 platform; VR gains config-override (#29)

Move the periodic cap-exceeded reaper (evaluate_cap_for_investigation +
sweep_cap_exceeded_investigations) to
aila.platform.services.investigation_reaper, generic over the module
investigation/branch/message record models, the ARQ track, and an async
cap_resolver returning a frozen CapConfig. VR and malware bind the platform
generic via module-level functools.partial; caller import sites and call
signatures stay unchanged.

Behavior change (VR): the VR reaper now resolves its four caps through
ConfigRegistry in the vr namespace instead of reading raw os.environ. An
override written via PUT /config now takes effect on the next reaper tick.
The VR config schema declares the four cap keys (investigation_turn_cap
default 300, investigation_message_cap 1000, investigation_wall_clock_hours
6.0, wall_clock_idle_grace_s 900.0) so the numeric defaults match the prior
literals -- a deployment without overrides sees no numeric change. The prior
VR_* env-var names are no longer read; the env surface is the standard
AILA_VR_<KEY> form. Malware behavior is unchanged (already ConfigRegistry
backed).

Rides the unreleased 0.3.0 line; no version bump.

-"""Periodic cap-exceeded sweep for malware investigations.
-
-The cap-check logic in ``investigation_emit`` only fires at turn
-boundaries. When workers are stuck in LLM-provider retry storms (300
-seconds + 100 retries per call observed live), the emit path never
-runs, the cap never evaluates, and an investigation past its
-wall-clock limit stays RUNNING for hours after it should have
-completed. Observed live 2026-06-03: 4 systemd investigations past
-6h wall-clock kept queueing auto-continue tasks because no worker
-could reach the cap-check at the turn boundary.
-
-This reaper runs every minute via the ARQ cron, INDEPENDENT of
-worker turn progress. It applies the same caps via the same
-mechanism (halt branches + complete investigation + arq-purge):
-
-  MALWARE_INVESTIGATION_TURN_CAP            (default 500, sum of branch turns)
-  MALWARE_INVESTIGATION_MESSAGE_CAP         (default 1000, total messages)
-  MALWARE_INVESTIGATION_WALL_CLOCK_HOURS    (default 6, investigation lifetime)
-
-The emit-side check stays in place as belt+suspenders -- it catches
-the cap faster (immediately on the turn that breached it) and lets
-the emit path log the breach next to the turn that caused it. The
-reaper is the catch-net for the stuck-worker case.

+the public names unchanged (``evaluate_cap_for_investigation`` +
+``sweep_cap_exceeded_investigations``); the emit path and the ARQ
+cron both address these bound partials directly.
+
+The resolver reads each cap through ``ConfigRegistry`` in the
+``malware`` namespace (layered lookup: ``AILA_MALWARE_<KEY>`` env ->
+DB -> schema default) and falls back to a hardcoded default if a
+value comes back ``None`` (bootstrap safety, matching the VR

-"""Periodic cap-exceeded sweep for VR investigations.
-
-The cap-check logic in ``investigation_emit`` only fires at turn
-boundaries. When workers are stuck in LLM-provider retry storms (300
-seconds + 100 retries per call observed live), the emit path never
-runs, the cap never evaluates, and an investigation past its
-wall-clock limit stays RUNNING for hours after it should have
-completed. Observed live 2026-06-03: 4 systemd investigations past
-6h wall-clock kept queueing auto-continue tasks because no worker
-could reach the cap-check at the turn boundary.
-
-This reaper runs every minute via the ARQ cron, INDEPENDENT of
-worker turn progress. It applies the same caps via the same
-mechanism (halt branches + complete investigation + arq-purge):
-
-  VR_INVESTIGATION_TURN_CAP            (default 300, sum of branch turns)
-  VR_INVESTIGATION_MESSAGE_CAP         (default 1000, total messages)
-  VR_INVESTIGATION_WALL_CLOCK_HOURS    (default 6, investigation lifetime)
-
-The emit-side check stays in place as belt+suspenders -- it catches
-the cap faster (immediately on the turn that breached it) and lets
-the emit path log the breach next to the turn that caused it. The
-reaper is the catch-net for the stuck-worker case.
+"""VR binding of the platform investigation cap-exceeded reaper.
+
+Binds the platform generic reaper functions to the VR record models,
+ARQ track name, and a namespaced :class:`ConfigRegistry`-backed
+``cap_resolver`` via module-level ``functools.partial``. Callers use
+the public names unchanged (``evaluate_cap_for_investigation`` +
+``sweep_cap_exceeded_investigations``); the emit path and the ARQ
+cron both address these bound partials directly.
+
+Adopts the platform generic to close a live bug: the prior VR reaper
+read caps from raw ``os.environ`` at every call and ignored operator
+overrides written via ``PUT /config``. This binding routes through
+``ConfigRegistry`` in the ``vr`` namespace so a DB override -- or an
+``AILA_VR_INVESTIGATION_TURN_CAP`` env var -- lands on the next tick
+without a worker restart. The prior ``VR_INVESTIGATION_TURN_CAP`` /
+``VR_INVESTIGATION_MESSAGE_CAP`` / ``VR_INVESTIGATION_WALL_CLOCK_HOURS``
+/ ``VR_WALL_CLOCK_IDLE_GRACE_S`` env-var names are no longer read;
+the operator-visible surface is the standard ``AILA_VR_<KEY>`` form.

+"""Periodic cap-exceeded sweep for module investigations.
+
+The cap-check logic in ``investigation_emit`` only fires at turn
+boundaries. When workers are stuck in LLM-provider retry storms (300
+seconds + 100 retries per call observed live), the emit path never
+runs, the cap never evaluates, and an investigation past its
+wall-clock limit stays RUNNING for hours after it should have
+completed. Observed live 2026-06-03: 4 systemd investigations past
+6h wall-clock kept queueing auto-continue tasks because no worker
+could reach the cap-check at the turn boundary.
+
+This reaper runs every minute via the ARQ cron, INDEPENDENT of
+worker turn progress. It applies the same caps via the same
+mechanism (halt branches + complete investigation + arq-purge).
+
+Generic over the module: callers bind their concrete investigation /
+branch / message record models, the ARQ track name, and an async
+``cap_resolver`` returning a :class:`CapConfig` via a module-level
+``functools.partial``. The platform file never names a module. The
+emit-side check stays in place as belt+suspenders -- it catches the
+cap faster (immediately on the turn that breached it) and lets the
+emit path log the breach next to the turn that caused it. The
+reaper is the catch-net for the stuck-worker case.

Subject: [PATCH 193/281] refactor(services): lift investigation finalizers to
 platform; malware gains zero-turn guard (#29)

Move the investigation finalizers (synthesize_no_finding_outcomes,
close_rejected_outcomes, abandon_stale_branches_impl and their per-id
wrappers) to aila.platform.services.investigation_finalizers, generic over the
module investigation/branch/outcome/outcome-review record models, the raw
branch/outcome table names, the module no_finding_outcome_kind, and a
module-supplied build_no_finding_payload callable. VR and malware bind the
platform generic via module-level functools.partial; caller import sites and
call signatures stay unchanged.

Behavior change (malware): zero-turn investigations -- every branch terminal
without completing a single reasoning turn -- now mark FAILED (retryable via
reopen / re-enqueue) instead of emitting a stalled_report outcome that read as
a clean completion. The zero-turn guard was previously VR-only; it is now the
platform default so every module inherits it. VR behavior is unchanged (it
already had the guard). Both modules keep their own no-finding outcome kind and
payload shape (VR audit_memo with verdict=no_finding; malware stalled_report
with turns_consumed / turn_cap / blocker / what_was_learned).

The LLM-unhealthy guard on synthesize_no_finding_outcomes and
abandon_stale_branches_impl is preserved. The guard test is retargeted to the
platform module where the guard now lives.

Rides the unreleased 0.3.0 line; no version bump.

-"""Investigation-level reconciliation helpers.
-
-Three helpers cover the post-run reconciliation paths an investigation
-needs before it can be parked in a terminal status:
-
-* ``close_rejected_outcomes`` / ``close_rejected_for_investigation`` --
-  closes investigations whose outcomes hit a rejected quorum so the
-  cron finalizer can mark them ``rejected``.
-* ``synthesize_no_finding_outcomes`` /
-  ``synthesize_no_finding_for_investigation`` -- synthesizes a
-  ``no_finding`` outcome for orphan investigations that finished
-  every branch without producing a stalled report.
-* ``abandon_stale_branches_impl`` / ``abandon_stale_branches`` --
-  marks long-idle ``active`` branches as ``abandoned`` so the
-  finalize chokepoint isn't blocked by branches whose worker died
-  silently.
-
-Called by the cron finalizer in :mod:`malware.workflow.finalize`.
-The per-id wrappers are also called directly from the api_router
-triage routes that need synchronous reconciliation on a single
-investigation without waiting for the next sweep tick.
+"""Malware binding of the platform investigation finalizers.
+
+Binds the platform generic finalizers to the malware ORM record
+models, raw table names, ``stalled_report`` outcome kind, and the
+malware-shaped no-finding payload via module-level
+:func:`functools.partial` bindings. Callers keep the same import
+site and call-signature they have today
+(``synthesize_no_finding_for_investigation(inv_id)``, etc.); each
+partial is a stable object across re-imports so any downstream
+identity-keyed registration (task registration, sweep-step
+reference) does not churn.
+
+Behavior change vs. the pre-lift malware finalizer: zero-turn
+investigations now mark ``FAILED`` (retryable) instead of emitting
+a ``stalled_report`` outcome that reads as a clean completion. The
+zero-turn guard is enforced by the platform generic; every
+consumer gains it automatically.
+
+The malware no-finding outcome is written as ``stalled_report``
+with a payload shape carrying ``turns_consumed`` / ``turn_cap`` /
+``blocker`` / ``what_was_learned`` so the operator UI renders it
+as an honest stalled report (see
+:class:`aila.modules.malware.contracts.outcome.StalledReportPayload`).
+The richer per-branch trace lives under ``branches`` alongside the
+core fields as an audit-trail addition; the dispatcher never
+round-trips this row through ``StalledReportPayload.model_validate``,
+so the extra key is harmless.

-"""Generic investigation finalizers -- implementation site.
-
-Three helpers that handle generic investigation finalization
-(rejected-quorum close, orphan audit_memo synthesis, stale-branch
-abandonment). They are not MASVS-specific; this module is their
-canonical home after Phase C's cleanup of the
-``vr.masvs.parent_reconciler`` overload.
-
-Two surface layers:
-
-* **Sweep impls** (``close_rejected_outcomes``,
-  ``synthesize_no_finding_outcomes``, ``abandon_stale_branches_impl``)
-  take a caller-supplied ``UnitOfWork``. Used by the cron sweep in
-  ``parent_reconciler.sweep_masvs_audit_parents`` so the whole batch
-  runs in one transaction.
-
-* **Per-id wrappers** (``close_rejected_for_investigation``,
-  ``synthesize_no_finding_for_investigation``,
-  ``abandon_stale_branches``) open their own ``UnitOfWork`` and pass
-  ``only_id=...`` where supported. Used by the Phase C finalize
-  chokepoint so a per-investigation invocation is O(1) instead of an
-  O(N) sweep scan.
-
-History: the implementations originally lived in
-:mod:`vr.masvs.parent_reconciler` because that's where the first
-cron sweep wiring landed. The 500+ lines of generic investigation
-logic was an accidental fit; this module is where they belong.
-``parent_reconciler.py`` now imports + delegates so MASVS-specific
-batch reconciliation stays the only thing under ``vr/masvs/``.
+"""VR binding of the platform investigation finalizers.
+
+Binds the platform generic finalizers to the VR ORM record models,
+raw table names, ``audit_memo`` outcome kind, and the VR-shaped
+no-finding payload via module-level :func:`functools.partial`
+bindings. Callers keep the same import site and call-signature they
+have today (``synthesize_no_finding_for_investigation(inv_id)``,
+``_synthesize_no_finding_outcomes(uow)``, etc.); each partial is a
+stable object across re-imports so any downstream identity-keyed
+registration (task registration, sweep-step reference) does not
+churn.
+
+The VR no-finding outcome is written as ``audit_memo`` with a
+payload shape carrying ``verdict='no_finding'``, a per-branch trace
+of persona / turns / closed_reason, and the standard
+synthesized_by / synthesized_at / rule provenance fields.

+"""Generic investigation finalizers -- implementation site.
+
+Three helpers that handle generic investigation finalization
+(rejected-quorum close, orphan no-finding synthesis, stale-branch
+abandonment). Generic over the caller module's ORM record models,
+the concrete raw table names touched by the raw-SQL INSERT + orphan
+branch UPDATE, and the concrete outcome_kind + payload shape a
+module wants written for the "every-terminal-branch, no outcome"
+orphan case (VR writes an ``audit_memo``; malware writes a
+``stalled_report``).
+
+Two surface layers:
+
+* **Sweep impls** (:func:`close_rejected_outcomes`,
+  :func:`synthesize_no_finding_outcomes`,
+  :func:`abandon_stale_branches_impl`) take a caller-supplied
+  :class:`UnitOfWork`. Used by the cron sweep so the whole batch
+  runs in one transaction.
+
+* **Per-id wrappers** (:func:`close_rejected_for_investigation`,
+  :func:`synthesize_no_finding_for_investigation`,
+  :func:`abandon_stale_branches`) open their own
+  :class:`UnitOfWork` and pass ``only_id=...`` where supported.
+  Used by the finalize chokepoint so a per-investigation
+  invocation is O(1) instead of an O(N) sweep scan.
+
+Module binding contract: each module's
+``services/investigation_finalizers.py`` wraps every callable here
+in a module-level :func:`functools.partial` that pre-binds the
+module's record models, the raw table names, the module's
+``no_finding_outcome_kind``, the module-specific
+``build_no_finding_payload`` callable, and the module's
+``get_int`` config helper. Callers keep the same import site and
+call-signature they have today.
+
+Zero-turn guard (operator rule): investigations where every branch
+reached terminal without completing a single reasoning turn never
+actually ran -- they are LLM-outage / dispatch-crash / immediate
+abandonment fallout, not a "we audited and found nothing" result.
+The synthesizer marks them ``FAILED`` (retryable via reopen /
+re-enqueue) instead of writing a hollow no-finding outcome that
+reads as a clean completion. This guard is the platform default so
+every module gets it.

Subject: [PATCH 194/281] test(rfc01): mcp_call_log residue is empty after
 join-key hoist (#29 #39)

93bffb8 hoisted the join-keys (investigation_id, branch_id, turn_number) to
McpCallLogRecordBase; the VR concrete now inherits them with no residue. Update
the residue expectation in test_remaining_record_bases_match_vr_minus_residue
from the three join-key names to the empty set so the base/concrete field
equality holds.

Subject: [PATCH 195/281] refactor(config): add ModuleConfigBase + unify typed
 config readers (#29)

RFC-04 Phase 2 core. Introduce aila.platform.config_base with:
- ModuleConfigBase: the single base every module config schema
  subclasses. It bakes in extra="forbid" so a config model constructed
  with an undeclared key fails closed. vr/malware/forensics re-base onto
  it and drop their own per-model ConfigDict(extra="forbid");
  vulnerability gains the fail-closed policy it was missing.
- ModuleConfigReader: namespace-bound typed config reads (get_int,
  get_float) over one process-wide ConfigRegistry, replacing the
  byte-identical vr and malware services/config_helpers.py singletons.
  Each module config_helpers.py becomes a thin binding that re-exports
  the bound methods, so every caller keeps the get_int(key) surface.

No runtime behavior change: the config schemas are read per-key via
ConfigRegistry, never validated against a full config dict, so the
vulnerability extra="forbid" only fails closed on a code-level
construction typo. Reads resolve identically (env -> DB -> schema
default).

Deviations from the RFC design (documented): the base lives at
platform/config_base.py rather than platform/config/ (platform/config is
already a module, not a package -- converting it would churn every
importer); the typed getters are a ModuleConfigReader class bound per
module rather than a get_typed method on the schema base (the schema is
a data model and callers read per-key without a schema instance);
llm_model is not hoisted onto the base (not every module is LLM-backed,
so forcing it onto vulnerability would add a meaningless key);
config_helpers.py is kept as a thin binding rather than deleted,
preserving every caller.

Rides the unreleased 0.3.0 line; no version bump.

Subject: [PATCH 196/281] feat(honesty): add rule 37 module_config_schema_base
 (#29)

RFC-04 Phase 2 guardrail. A *ConfigSchema class in a
modules/<name>/config_schema.py file must subclass
aila.platform.config_base.ModuleConfigBase (which bakes in
extra="forbid") rather than bare BaseModel. This locks in the
fail-closed config policy so a new module cannot regress to permissive
validation the way vulnerability/config_schema.py had before Phase 2.
Scoped by path to config_schema.py and by name to *ConfigSchema classes
so nested helper models stay out of scope. Three fixture tests: fires on
bare BaseModel, silent on ModuleConfigBase, silent outside
config_schema.py.

Rides the unreleased 0.3.0 line; no version bump.

Subject: [PATCH 197/281] fix(vr): finalize cap-check reads caps via
 ConfigRegistry (#29)

VR finalize._detect_trigger read its four caps (wall_clock_hours /
turn_cap / message_cap / idle_grace_s) from raw os.environ via
_float_env / _int_env, while the cap reaper (712ce3e) resolves them
through ConfigRegistry. That left VR's two cap-check paths disagreeing
under a PUT /config DB override -- the reaper honored it, finalize did
not. Migrate finalize to the config_helpers get_int / get_float readers
so both paths resolve identically (env -> DB -> schema default),
matching the malware finalizer.

Behavior change: the VR turn-boundary cap-check now honors DB config
overrides; the legacy VR_* env-var names are no longer read (use the
canonical AILA_VR_<KEY> form). Value defaults unchanged (6.0h / 300 /
1000 / 900s). Removes the now-unused _float_env / _int_env helpers and
the os import.

Rides the unreleased 0.3.0 line; no version bump.

Subject: [PATCH 198/281] feat(honesty): add rule 38 service_copy_of_platform
 (#29)

RFC-04 re-duplication guardrail. A file under modules/vr/services or
modules/malware/services whose comment- and format-normalized body
(ast.unparse) is at least 75% similar to a platform service
(platform/services, platform/mcp, platform/tasks) is flagged as a
copy-and-rename -- the pattern RFC-04 lifted out. After a lift the module
keeps only a thin binding, so a high-similarity match means a full copy
slipped back in.

Scoped to the vr/malware copy set; forensics keeps an independent
machine_readiness variant and stays outside the check. A length-ceiling
pre-filter (2*min/(sum) below threshold) plus SequenceMatcher.quick_ratio
prune the O(n*m) compare so the audit stays fast; thin bindings are too
short to reach the threshold against a full impl. Three fixture tests:
fires on a near-copy, silent on a thin binding, silent for forensics.

Rides the unreleased 0.3.0 line; no version bump.

Subject: [PATCH 199/281] refactor(services): lift investigation pause/resume
 to platform (#27)

RFC-02 Phase 0 (pause + resume). Move the atomic pause / resume
lifecycle to aila.platform.services.investigation_lifecycle, generic
over the investigation and branch record models, the raw branch table
name, the ARQ track, and the module task function. The four-source-of-
truth ordering (lock the inv row, lock + flip the workflow_state_cursor
rows, cancel the taskrecord rows, flip the branch projection, commit,
then best-effort ARQ purge + cancellation-token flip) is preserved from
the VR reference implementation.

VR workflow/pause_resume.py becomes thin wrappers binding the VR record
models, the vr branch table, track="vr", and run_vr_investigate; the
pause-reason enum coercion stays VR-side. The api_router pause / resume
handlers are unchanged -- they still import pause_investigation_atomic /
resume_investigation_atomic from the VR binding, which now delegate to
the platform service. Behavior-preserving for VR (the reference-correct
implementation).

The 18-test Phase-B pause/resume regression suite passes through the
lifted path. Reenqueue and the malware migration (which fixes the
malware pause/resume/reenqueue bugs) land in follow-up commits.

Rides the unreleased 0.3.0 line; no version bump.

-"""Phase B (cutover): atomic pause / resume / reset implementations.
-
-Promotes ``workflow_state_cursor`` to the single source of truth for
-"is this investigation paused right now". The prior implementation
-wrote ``inv.status = PAUSED`` directly from the API handler, leaving
-three sources of truth unsynchronized (``TaskRecord.status``,
-``workflow_state_cursor.current_state``, ``arq:in-progress:<id>``).
-Per `prior design notes` Phase B closes items §3, §30-§33,
-§46, §47, §156, §287, §288, §296.
-
-Three operations expose the same atomic-transaction shape:
-
-* :func:`pause_investigation_atomic`
-    SELECT FOR UPDATE every branch's cursor that belongs to the
-    investigation → flip ``current_state -> '__paused__'`` while
-    archiving the prior state → cancel TaskRecord rows in
-    ``queued/running/waiting`` → flip ``inv.status -> PAUSED``
-    derived projection. One transaction, one commit. ARQ purge runs
-    AFTER the commit (best-effort: surviving jobs read the cursor on
-    next pickup, see ``__paused__``, and exit clean).
-
-* :func:`resume_investigation_atomic`
-    SELECT FOR UPDATE every cursor with ``current_state ==
-    '__paused__'`` → restore ``archived_state -> current_state`` and
-    clear archive → flip ``inv.status -> RUNNING``. AFTER commit,
-    fan-out one ``run_vr_investigate`` ARQ task per resumed cursor so
-    every branch (not just the primary) actually ticks again.
-
-* :func:`reset_investigation_atomic`
-    Pause + delete every cursor + clear every outcome → spawn a fresh
-    primary branch. Matches the observed contract that
-    ``/reset`` returns the investigation to a pristine state.
-
-Mid-LLM-call cancellation (Phase B.5 in the design doc) is deferred:
-in-flight LLM calls commit when they finish, which can be minutes
-after the pause. The next turn-boundary tries to acquire the cursor
-lock, sees ``__paused__``, and exits. No further work happens.

+"""Atomic investigation pause / resume across the four sources of truth.
+
+The durable lifecycle of an investigation touches four stores that must
+move together:
+
+1. the ``<module>_investigation`` row (projection column ``status`` plus
+   ``pause_reason`` / ``updated_at``);
+2. ``workflow_state_cursor`` (per-branch ``current_state`` /
+   ``archived_state`` and the ``__paused__`` sentinel);
+3. ``taskrecord`` (ARQ task rows in ``queued`` / ``running`` /
+   ``waiting``);
+4. ARQ Redis (``arq:in-progress:<id>`` keys and queued jobs).
+
+Correctness comes from doing the mutable three (inv row, cursor rows,
+taskrecord rows) in one transaction with the right ordering (lock the
+inv row, then the cursors, flip everything, commit) and then doing the
+best-effort ARQ Redis purge after commit. That ordering is a platform
+property, not a module one: it sits above the persona roster and MCP
+catalog. Leaving it per module gives every new module the choice of
+copying the correct version, copying a stale one, or writing a third --
+which is exactly how the malware copy fell behind. One implementation
+forces one behavior.
+
+Generic over the module: callers bind their concrete investigation and
+branch record models, the raw branch table name (for the operator-facing
+branch-status projection), the ARQ track, and the module task function
+via a thin module wrapper. The platform file never names a module. The
+pause-reason enum coercion stays module-side (each module validates its
+own reason vocabulary) and the already-coerced string is passed in.

Subject: [PATCH 200/281] refactor(services): lift investigation reenqueue to
 platform (#27)

RFC-02 Phase 0 (reenqueue) -- completes the VR lifecycle lift. Add
reenqueue_investigation to aila.platform.services.investigation_lifecycle,
generic over the investigation model, ARQ track, task function, and the
fn-path pattern used to match stale task rows. The reset sequence (lock
inv, optional kind/strategy update, status to CREATED, cancel stale
taskrecords so submit's input-hash dedup does not return the prior
handle, wipe __crashed__ cursors, commit before submit) is preserved
from the VR reference implementation.

VR workflow/pause_resume.py gains a reenqueue_investigation_atomic thin
binding. The VR api_router reenqueue handler drops its inline body and
dispatches to the binding, keeping the team-filter auth check and the
summary projection; the now-unused TaskRecord / TaskStatus imports are
removed. Behavior-preserving for VR.

Three fixture tests cover the reset+cancel+wipe+submit path, the
not-found error, and the kind/strategy update. The full 21-test
pause/resume/reenqueue suite passes through the lifted path.

Rides the unreleased 0.3.0 line; no version bump.

Subject: [PATCH 201/281] fix(malware): route pause/resume through the platform
 lifecycle service (#27)

RFC-02 Phase 1 (malware pause/resume). The malware api_router pause and
resume handlers wrote record.status directly and never touched the
workflow cursors, taskrecord rows, or ARQ -- a resumed malware
investigation showed RUNNING with nothing dispatched, no cursor
restored, and no worker task submitted. Route both handlers through the
platform investigation_lifecycle service via new malware pause_resume.py
thin bindings, so malware now runs the same atomic four-source-of-truth
sequence VR does.

Behavior change (the fix): pausing a malware investigation now flips the
inv row, the workflow cursors, and the taskrecord rows in one
transaction and purges ARQ; resuming restores the cursors and fans out
one worker task per resumed branch. Pausing a terminal investigation now
returns 409 instead of silently setting PAUSED.

Verification: the platform pause/resume path is covered by the 21-test
VR Phase-B suite (identical code path); the malware models and the
malware_investigation_branches table literal are confirmed compatible.
End-to-end behavior on a running malware investigation is the operator
live-smoke gate per RFC-02. Malware reenqueue (which has a different
submit model) lands in a follow-up.

Rides the unreleased 0.3.0 line; no version bump.

-"""Phase B (cutover): atomic pause / resume / reset implementations.
-
-Promotes ``workflow_state_cursor`` to the single source of truth for
-"is this investigation paused right now". The prior implementation
-wrote ``inv.status = PAUSED`` directly from the API handler, leaving
-three sources of truth unsynchronized (``TaskRecord.status``,
-``workflow_state_cursor.current_state``, ``arq:in-progress:<id>``).
-Per `prior design notes` Phase B closes items §3, §30-§33,
-§46, §47, §156, §287, §288, §296.
-
-Three operations expose the same atomic-transaction shape:
-
-* :func:`pause_investigation_atomic`
-    SELECT FOR UPDATE every branch's cursor that belongs to the
-    investigation → flip ``current_state -> '__paused__'`` while
-    archiving the prior state → cancel TaskRecord rows in
-    ``queued/running/waiting`` → flip ``inv.status -> PAUSED``
-    derived projection. One transaction, one commit. ARQ purge runs
-    AFTER the commit (best-effort: surviving jobs read the cursor on
-    next pickup, see ``__paused__``, and exit clean).
-
-* :func:`resume_investigation_atomic`
-    SELECT FOR UPDATE every cursor with ``current_state ==
-    '__paused__'`` → restore ``archived_state -> current_state`` and
-    clear archive → flip ``inv.status -> RUNNING``. AFTER commit,
-    fan-out one ``run_malware_investigate`` ARQ task per resumed cursor so
-    every branch (not just the primary) actually ticks again.
-
-* :func:`reset_investigation_atomic`
-    Pause + delete every cursor + clear every outcome → spawn a fresh
-    primary branch. Matches the observed contract that
-    ``/reset`` returns the investigation to a pristine state.
-
-Mid-LLM-call cancellation (Phase B.5 in the design doc) is deferred:
-in-flight LLM calls commit when they finish, which can be minutes
-after the pause. The next turn-boundary tries to acquire the cursor
-lock, sees ``__paused__``, and exits. No further work happens.
+"""Malware binding of the platform investigation lifecycle service.
+
+Thin wrappers over :mod:`aila.platform.services.investigation_lifecycle`:
+pause / resume are bound to the malware record models, the malware branch
+table, the ``malware`` ARQ track, and ``run_malware_investigate``. The
+pause-reason enum coercion stays here (malware owns its reason
+vocabulary); the platform takes the already-coerced value.
+
+Before this binding the malware api_router pause / resume handlers wrote
+``record.status`` directly without touching the workflow cursors, the
+taskrecord rows, or ARQ -- a resumed malware investigation showed
+RUNNING with nothing dispatched. Routing through the platform service
+closes that drift; malware now runs the same atomic four-source-of-truth
+sequence VR does.

Subject: [PATCH 202/281] fix(malware): log pause/resume lifecycle summary for
 VR parity (#27)

The malware pause/resume handlers discarded the summary the platform
lifecycle service returns; the VR handlers log paused_cursors /
cancelled_tasks / resumed_cursors / submitted_tasks for operator
debugging. Capture and log the same lines on the malware side so the two
modules produce parallel lifecycle audit trails.

Rides the unreleased 0.3.0 line; no version bump.

Subject: [PATCH 203/281] fix(malware): own re-enqueue state machine at the
 platform boundary (#27)

The malware re-enqueue handler submitted fresh worker tasks without
resetting the investigation to CREATED, cancelling stale taskrecords,
or wiping __crashed__ workflow_state_cursor rows. The fresh task was
created (the malware submit primitive bypasses input-hash dedup) but
died immediately on the crashed cursor, so re-enqueue silently no-opped
on a crashed investigation.

Move the full re-enqueue state machine into the platform lifecycle
service so a module cannot diverge: reset, stale-cancel, crashed-wipe,
and the branch fan-out orchestration are all platform-owned. The only
module-specific input is the atomic submit primitive
submit_one(investigation_id, branch_id | None) plus the branch-query
parameters as data. An unset branch_model selects submit-once (VR,
whose setup respawns the branches); a branch model submits one task per
active branch, or one setup task when none is active (malware).

- platform reenqueue_investigation: submit_fn replaced by submit_one
  plus branch_model and branch_status_active; new
  _fan_out_reenqueue_submit owns the per-branch fan-out.
- vr pause_resume binding: supplies a submit-once primitive; its public
  signature is unchanged, so the handler and existing tests stay put.
- malware re-enqueue handler: supplies _default_submit_fn as the submit
  primitive plus the branch model and active-status value; the
  hand-written fan-out loop is gone.
- tests: two platform fan-out tests (per-active-branch, and the
  no-active-branch single-setup fallback).

No schema change; rides the unreleased 0.3.0 line.

Subject: [PATCH 204/281] fix(malware): report live investigation cost via
 platform aggregator (#27)

The malware investigation summary read cost_actual_usd directly. That
column has no writers, so the budget gauge reported a permanent $0
regardless of actual spend. VR already aggregated LLMCostRecord per
investigation but kept its own copy of the aggregator.

Add platform services/investigation_cost.compute_live_investigation_cost
as the single implementation: sum LLMCostRecord.cost_usd filtered by
run_id, which both reasoning engines thread as the investigation id
(malware_researcher passes run_id=investigation_id; the vr turn engine
threads it through decide_next_turn). Best-effort: returns 0.0 on any
query error so the read path never crashes on the gauge.

- vr api_router: drop the local _compute_live_investigation_cost and its
  now-unused LLMCostRecord import; the single GET calls the platform
  aggregator. No behavior change (same run_id filter, same result).
- malware api_router: _investigation_summary gains a live_cost_usd
  override; the single GET aggregates and passes it. This is the fix:
  the malware gauge now reflects real spend.
- tests: platform aggregator sums only the matching run_id and returns
  0.0 when no rows exist.

No schema change; rides the unreleased 0.3.0 line.

Subject: [PATCH 205/281] refactor(platform): share the investigation summary
 projection (#27)

The vr and malware *InvestigationSummary contracts are field-identical,
but each module carried its own _investigation_summary projection. They
had already drifted once (the malware cost gauge). Add
platform/services/investigation_summaries.build_investigation_summary as
the single projection into either contract via summary_cls; each module
keeps a thin binding that supplies its own contract class, so all call
sites per module (list, detail, every lifecycle handler return) stay
unchanged.

The builder passes the raw string columns (kind/status/pause_reason) and
relies on each contract to coerce them to its own module enum, so the
platform never imports a module enum. No behavior change: the projected
fields, live_cost_usd override, and enum values match the per-module
versions.

- new: platform/services/investigation_summaries.py.
- vr/malware api_router: _investigation_summary becomes a thin binding
  of the shared builder (whitelisted as Category g facades).
- tests: builder projects into both contracts, coerces kind/status, and
  honors the live_cost_usd override.

RFC-02 Phase 2 (summary builders). The branch/message/outcome summaries
diverge (malware adds acked_at and quorum counts) and stay per-module
pending the extra-field mechanism. No schema change; rides 0.3.0.

Subject: [PATCH 206/281] refactor(platform): share the persona sibling spawn
 (#27)

The two-phase atomic persona spawn was a byte-identical s/vr/malware/
copy (~250 lines each) inside both setup states: lock the inv row,
dedup branches by persona (operator_reopen wins, then highest turn,
then newest), reactivate the winner to a fresh slot (turn_count reset,
case_state stripped, prior messages deleted), abandon duplicates, and
INSERT a branch per missing persona, then best-effort enqueue one task
per resolved branch.

Extract it to platform/workflows/persona_spawn.spawn_persona_siblings,
generic over the branch model, table names, persona tuple, task
function, ARQ track and group, and the case_state strip composition.
Each module _spawn_persona_siblings_and_enqueue becomes a thin binding.
Behavior-preserving: the body is the same statements with only the
module tokens parameterized.

- new: platform/workflows/persona_spawn.py (SiblingSpawnResult plus
  spawn_persona_siblings).
- vr/malware investigation_setup: the spawn body is replaced by the
  binding; the now-unused _sql_text and WorkerUnreachableError imports
  are dropped.
- tests: the extracted spawn inserts a missing persona, reactivates the
  winner (turn reset plus message wipe), abandons a duplicate, and
  enqueues one task per resolved branch.

RFC-02 Phase 3. No schema change; rides 0.3.0.

+"""Platform persona sibling spawn (RFC-02 Phase 3).
+
+Two-phase atomic spawn of one branch per persona for an investigation,
+extracted from the vr and malware setup states (which were a
+byte-identical ``s/vr/malware/`` copy). The module binds its concrete
+branch model, table names, persona tuple, task function, ARQ track and
+group, and the case_state strip composition; the platform never names a
+module.
+
+Phase 1 (atomic UnitOfWork, one commit): lock the inv row so parallel
+spawn ticks serialize; group every existing branch by persona and pick
+the winner (an ``operator_reopen:`` branch always wins, then highest
+turn_count, then newest); reactivate the winner to a fresh slot
+(turn_count 0, stripped case_state, prior messages deleted so the
+tool-failure breaker starts clean); abandon duplicates; and INSERT a
+branch for every persona without one. Any raise rolls the whole panel
+back -- either all siblings resolve to a stable id or none do.
+
+Phase 2 (best-effort): submit one worker task per resolved branch. A
+single enqueue failure logs and continues because the branch row
+already persists from phase 1, so a reaper-on-cursor sweep can resubmit
+it. An empty ``siblings`` tuple is a valid no-op for single-agent
+modules.

Subject: [PATCH 207/281] fix(malware): live spend on the /cost endpoint via
 platform aggregator (#27)

The dedicated GET /investigations/{id}/cost endpoint read the stored
cost_actual_usd column (no writers) and reported a permanent $0 for
actual_usd, remaining_usd, and budget_used_pct -- separate from the
summary path fixed earlier. Aggregate LLMCostRecord by run_id through
the shared platform compute_live_investigation_cost so all three fields
reflect real spend.

Completes the RFC-02 Phase 2 cost work: no module api_router now reads
cost_actual_usd in a response body. Behavior change (the fix); no schema
change; rides 0.3.0.

Subject: [PATCH 208/281] feat(honesty): guardrails against lifecycle + cost
 re-drift (#27)

Add two AST honesty rules that make the drift class behind the malware
lifecycle and cost bugs impossible to reintroduce:

- cost_read_stored_actual (rule 39): flag a vr/malware api_router that
  reads record.cost_actual_usd in a response without a
  compute_live_investigation_cost call in the same function. The column
  has no writers, so a stored read reports a permanent $0. The
  create-time cost_actual_usd=0.0 insert is a keyword, not a read, so it
  never trips.

- lifecycle_handler_bypass_service (rule 40): flag a pause / resume /
  re-enqueue route handler that writes .status directly instead of
  routing through the platform investigation lifecycle service. reset is
  excluded (a full-wipe that legitimately resets status).

Both scoped to the vr/malware api_router. Baseline is zero after the
Phase 0-2 consolidations landed this cycle. Seven fixture tests: each
rule fires on a violation and stays silent on the legit pattern
(aggregator present, delegating handler, reset, out-of-scope module).

RFC-02 guardrails. No schema change; rides 0.3.0.

Subject: [PATCH 209/281] refactor(platform): extract the investigation setup
 state factory (#27)

The setup state was 84% duplicated across vr and malware (440/378
lines): the stale-branch self-heal, orphan-abandon, RUNNING-flip
whitelist, and knowledge-transfer pattern lookup were byte-identical;
only the CVE-intel weaving differed (vr resolves, malware has none).

Extract it to platform/workflows/investigation_setup_base:
state_investigation_setup(bindings, hooks) returns the state handler.
The module binds its record models, primary persona, sibling-spawn
function, pattern-store factory, and auto-deliberation toggle;
resolve_cve_intel is an optional hook. Malware leaves it unset and the
cve_intel output is an empty list the malware loop ignores (the setup
StateSpec declares no output_schema, so the extra key is inert).
InvestigationStateBindings and InvestigationStateHooks are the shared
dataclasses the loop and emit factories will reuse.

- new: platform/workflows/investigation_setup_base.py.
- vr/malware investigation_setup: state_investigation_setup is now the
  factory bound to the module; vr keeps a _resolve_cve_intel hook. Dead
  constants (_STATUS_LOCKED, _DEAD_BRANCH_STATUSES, the pattern-lookup
  counter) and now-unused imports dropped.
- tests: fresh-primary fork (RUNNING flip plus spawn plus cve intel),
  no-cve-hook empty cve_intel, status_locked clean exit,
  sibling-terminal exit, and orphan-abandon on fresh fork.

RFC-02 Phase 4a. No schema change; rides 0.3.0.

-    Stale-branch self-healing (added after observing an investigation
-    polling a closed halvar branch after re-enqueue):
-
-      * **Primary task path** (no explicit branch_id): when picking the
-        primary branch via ``parent_branch_id IS NULL``, filter to
-        ``status IN (ACTIVE, PAUSED)`` AND order by ``created_at ASC``
-        for determinism. If ALL prior primary branches are terminal
-        (COMPLETED / MERGED / PROMOTED / ABANDONED) -- which is the
-        post-completion / post-failure re-enqueue case -- fork a fresh
-        primary branch instead of resuming a closed one. Without this,
-        ``re-enqueue`` after a successful or failed run silently
-        operates on the prior terminal branch, drives investigation_loop
-        against a dead branch, and the workflow never makes progress.
-
-      * **Sibling task path** (explicit_branch_id set): when the named
-        branch is already terminal, return a clean terminal exit
-        (``next_state="investigation_emit"`` with
-        ``exit_reason="branch_already_terminal"``) instead of entering
-        investigation_loop. This catches the case where a sibling task
-        was queued, the branch terminal-submitted via another path
-        before the task ran, and the cursor would otherwise enter the
-        loop on a closed branch.
-
-    Both paths leave a structured log line so the operator can audit
-    when the self-heal fired.
-
-    UoW contract (fix §291 -- explicit doc of the all-or-nothing
-    invariant that already holds structurally):
-
-    The single ``async with UnitOfWork() as uow`` block that wraps
-    investigation load → STATUS_LOCKED check → primary branch
-    resolve → orphan-abandon → fresh-primary INSERT → status flip
-    → ``uow.commit()`` is an **atomic transaction**. The orphan
-    cleanup (mark sibling ACTIVE/PAUSED branches ABANDONED with
-    ``superseded_by_reenqueue_self_heal:<new>``) and the fresh
-    primary INSERT MUST commit together. If any pre-commit step
-    raises (engine error, integrity violation, transient DB hiccup),
-    the surrounding ``with`` block rolls everything back -- orphan
-    rows stay ACTIVE, no fresh primary row leaks, the cursor
-    re-fires next ARQ task wakeup.
-
-    Anyone editing this block: do NOT split the orphan-abandon and
-    fresh-primary INSERT into separate UoWs. The whole point is
-    that a half-applied self-heal (new primary lives, orphans stay
-    racing) is worse than no self-heal -- it produces exactly the
-    "6 branches instead of 3" state we just fixed in 2026-05-28.

+"""Investigation setup state factory (RFC-02 Phase 4).
+
+Extracted from the vr and malware setup states, which were byte-identical
+apart from the CVE-intel weaving. That weaving is now the optional
+``resolve_cve_intel`` hook: vr binds a resolver, malware leaves it unset
+and the ``cve_intel`` output is an empty list the malware loop ignores.
+
+The module binds its record models, primary persona, sibling-spawn
+function, pattern-store factory, and auto-deliberation toggle; the
+platform owns the stale-branch self-heal, orphan-abandon, status-flip
+whitelist, and knowledge-transfer pattern lookup. One implementation
+forces one behavior across every module.

+        Stale-branch self-healing (added after observing an investigation
+        polling a closed halvar branch after re-enqueue):
+
+          * **Primary task path** (no explicit branch_id): when picking the
+            primary branch via ``parent_branch_id IS NULL``, filter to
+            ``status IN (ACTIVE, PAUSED)`` AND order by ``created_at ASC``
+            for determinism. If ALL prior primary branches are terminal
+            (COMPLETED / MERGED / PROMOTED / ABANDONED) -- which is the
+            post-completion / post-failure re-enqueue case -- fork a fresh
+            primary branch instead of resuming a closed one. Without this,
+            ``re-enqueue`` after a successful or failed run silently
+            operates on the prior terminal branch, drives investigation_loop
+            against a dead branch, and the workflow never makes progress.
+
+          * **Sibling task path** (explicit_branch_id set): when the named
+            branch is already terminal, return a clean terminal exit
+            (``next_state="investigation_emit"`` with
+            ``exit_reason="branch_already_terminal"``) instead of entering
+            investigation_loop. This catches the case where a sibling task
+            was queued, the branch terminal-submitted via another path
+            before the task ran, and the cursor would otherwise enter the
+            loop on a closed branch.
+
+        Both paths leave a structured log line so the operator can audit
+        when the self-heal fired.
+
+        UoW contract (fix §291 -- explicit doc of the all-or-nothing
+        invariant that already holds structurally):
+
+        The single ``async with UnitOfWork() as uow`` block that wraps
+        investigation load → STATUS_LOCKED check → primary branch
+        resolve → orphan-abandon → fresh-primary INSERT → status flip
+        → ``uow.commit()`` is an **atomic transaction**. The orphan
+        cleanup (mark sibling ACTIVE/PAUSED branches ABANDONED with
+        ``superseded_by_reenqueue_self_heal:<new>``) and the fresh
+        primary INSERT MUST commit together. If any pre-commit step
+        raises (engine error, integrity violation, transient DB hiccup),
+        the surrounding ``with`` block rolls everything back -- orphan
+        rows stay ACTIVE, no fresh primary row leaks, the cursor
+        re-fires next ARQ task wakeup.
+
+        Anyone editing this block: do NOT split the orphan-abandon and
+        fresh-primary INSERT into separate UoWs. The whole point is
+        that a half-applied self-heal (new primary lives, orphans stay
+        racing) is worse than no self-heal -- it produces exactly the

the per-turn liveness poll (inv status, branch status, cursor SSOT,
cancellation token), the run_turn loop, tool dispatch, and terminal/cap
handling were identical; only the researcher class, tool-executor
bridges, config key, and researcher-error type differed.

Extract it to platform/workflows/investigation_loop_base:
state_investigation_loop(bindings, hooks) returns the handler, and
_is_loop_alive moves to the platform parameterized on the record models.
The module binds a researcher_factory (vr passes cve_intel, malware does
not), an executor_factory (the per-worker ToolExecutor singleton), a
max_turns_reader (the config key differs), and the researcher_error type.

- new: platform/workflows/investigation_loop_base.py.
- InvestigationStateBindings gains the loop fields; the setup-specific
  fields become optional so a loop-only bindings supplies just its
  subset (only inv_model and branch_model are shared-required).
- vr/malware investigation_loop: state_investigation_loop is the factory
  bound to the module; the module keeps its _get_executor singleton.
- tests: terminal-submit exit, max-turns cap, paused-investigation
  pre-turn exit, and tool_run dispatch to the executor.

RFC-02 Phase 4b. No schema change; rides 0.3.0.

Subject: [PATCH 211/281] feat(honesty): guardrail against workflow-state
 re-copy (#27)

Add honesty rule 41 workflow_state_copy_of_platform: a vr/malware
investigation state file (setup/loop/emit) whose normalized body is at
least 75% similar to a platform workflows/investigation_*_base.py is
flagged as a copy of the extracted state factory. RFC-02 Phase 4 moved
the setup and loop turn engine to the platform; each module keeps only a
thin factory binding, so a same-size copy means the drift slipped back
in. The length ceiling keeps thin bindings well under the threshold.

Baseline zero after Phases 4a and 4b (the module setup/loop files are
thin bindings). Three fixture tests: a near-copy under a module state
path fires, a thin binding stays silent, and forensics is out of scope.

RFC-02 guardrails. No schema change; rides 0.3.0.

Subject: [PATCH 212/281] refactor(platform): investigation emit state to
 platform factory (RFC-02 Phase 4c)

Extract the investigation-emit finalization engine into
platform/workflows/investigation_emit_base.py. The vr and malware emit
states were 94% identical: auto-continue on max_turns, the
investigation-level cap-exceeded halt (turns / messages / wall-clock
with idle grace), terminal status resolution, orphan-branch cleanup, the
draft-outcome review and dispatch workflow, synthesis and adversarial
verifier triggers, knowledge pattern extraction, and the finalize
chokepoint are now platform-owned. Both module emit modules become thin
lazy-built bindings supplying record models, task functions, config
readers, agents, and (malware only) the pattern and playbook proposer
hooks.

The one behavioral change: vr previously read its caps from module-load
os.environ constants; it now reads them live from ConfigRegistry via the
module config readers, matching malware. Cap default values are
unchanged (overall 500, investigation 300 turns / 1000 messages / 6.0h /
900s idle grace), so a non-overriding operator sees identical
termination behavior while vr gains live-tunable caps. Adds
overall_turn_cap (default 500) to the vr config schema.

The task functions are imported lazily on first handler call: they live
in the module workflow.task module which imports workflow.definitions
(which imports the emit state), so a module-level task import would be
circular.

Adds tests/platform/test_investigation_emit_base.py covering
auto-continue under cap, the investigation-turn-cap halt with branch
abandon, the reopen-window status guard, and proposer-hook firing.

+"""Investigation emit state factory (RFC-02 Phase 4c).
+
+Extracted from the vr and malware emit states (94% identical). The
+finalization engine -- auto-continue, the investigation-level cap-exceeded
+halt (turns / messages / wall-clock with idle grace), terminal status
+resolution, orphan-branch cleanup, the draft-outcome review + dispatch
+workflow, the synthesis and adversarial-verifier triggers, knowledge
+pattern extraction, and the finalize chokepoint -- is platform-owned.
+
+The one behavioral divergence RFC-02 resolves here: vr read its caps from
+module-load ``os.environ`` constants (the os.getenv anti-pattern), while
+malware read the same caps live from ``ConfigRegistry``. Both now read
+live via the module ``get_int`` / ``get_float`` bindings; the default cap
+values are unchanged (overall 500, investigation 300 turns / 1000 msgs /
+6.0h / 900s idle grace), so a non-overriding operator sees identical
+behavior while vr gains live tunability.
+
+The module binds its record models, task functions (investigate /
+synthesis / claim-verifier), ARQ track, config readers, outcome
+dispatcher + pattern extractor classes, pattern-store factory,
+outcome-review helpers, finalize function, and branch table. The
+post-completion proposers are optional hooks (malware sets
+propose_pattern / propose_playbook; vr leaves them unset).

Subject: [PATCH 213/281] refactor(platform): shared terminal-transition helper
 (RFC-02)

Extract the byte-identical _mark_investigation_completed from both
synthesis agents into platform/services/investigation_lifecycle.py as
mark_investigation_completed. Both modules flipped an investigation row
to COMPLETED with the same three-field write (status / stopped_at /
updated_at at one timestamp); the local helpers' own docstrings
anticipated a shared version they could be swapped for without touching
call sites. Now every terminal writer agrees on the field set through one
platform function that also accepts a shared now for batched writes.

Adds tests/platform/test_investigation_lifecycle_helpers.py asserting the
three fields move together to a single timestamp.

Subject: [PATCH 214/281] refactor(platform): lift auto-steering + intent
 classifier to platform/agents (RFC-03 Phase 1)

Create src/aila/platform/agents/ and move the two zero-drift agent
primitives up: the operator-intent classifier (classify_intent) and the
automatic operator-steering injector (maybe_post_auto_steering). Both
were byte-identical across the vr and malware copies modulo the record
types and the module import prefix.

auto_steering's five db-touching functions now take the message and
branch record models as parameters; the pure detectors, correction
derivers, and the acked-observable normalizer move up unchanged. The vr
and malware tool executors pass their own record models into
maybe_post_auto_steering; the researchers import the acked-observable
normalizer from platform; the vr api_router imports classify_intent from
platform. OperatorIntent, PayloadKind, and SenderKind are sourced from
platform.contracts. Both module copies are deleted -- callers cut over
directly, no re-export shim.

Adds honesty rule 42 agent_primitive_reimplementation: a module agents/
file defining classify_intent or maybe_post_auto_steering at top level is
a finding, so a copy cannot drift back in. Brings the header rule list
current (39-42).

Adds tests/platform/test_auto_steering.py (kwarg-rejection post + dedup
through vr models) and moves the intent-classifier tests to
tests/platform/. Behavior-preserving; no schema change.

-"""Operator message intent classifier (D-43 GA-30).

-cheap (no LLM call), deterministic (so tests are stable), and covers the
-common cases. Ambiguous inputs fall back to ``UNCLASSIFIED`` -- the
-engine still sees the raw text and can interpret freely.

Subject: [PATCH 215/281] refactor(platform): sibling-consensus injector to
 platform/agents (RFC-03 Phase 2)

Extract the sibling-consensus rejection block (byte-identical 52-line
copy in both turn runners) into
platform/agents/sibling_consensus.py:inject_sibling_consensus. When 2+
sibling branches have rejected a hypothesis this branch still holds live,
the injector writes the _directive.sibling_consensus_rejection observable
so the next turn's prompt confronts the agent with the consensus. Pure
function: no DB, mutates only case_state.observables. Both vr and malware
run_turn now compute my_live_ids from their own hypothesis shape and
delegate the rest.

Adds tests/platform/test_sibling_consensus.py pinning the 2-sibling
threshold, the directive payload, and the not-live-id / empty-input
no-ops. Behavior-preserving; no schema change.

Subject: [PATCH 216/281] fix(platform): idempotent LLM wrapper closes
 claim-verifier double-pay (RFC-03 Phase 2)

Add platform/agents/idempotent_llm.py:idempotent_llm_call, a retry-safe
front door over llm_client.chat / chat_json / chat_structured (all return
LLMResponse). It keys the response by (investigation_id, branch_id,
turn_number, method, task_type, messages [, schema/model]); a retried
worker recomputes the same key and replays the stored response instead of
paying the model API a second time. Keying on the full messages makes a
stale hit impossible -- any request change yields a different key.
Disabled (kill-switch) responses are never cached.

Adopt it at the four claim-verifier chat sites (vr + malware, extractor +
verdict), which called llm_client.chat directly and double-paid on ARQ
redelivery. Behavior is preserved: the wrapper returns the same
LLMResponse the direct call produced, and the verifier re-parses .content
unchanged.

Add honesty rule 43 agent_llm_chat_bypass: a direct llm_client.chat() in
a module agents/ file is a finding, so the bypass cannot return. The
chat_json (pattern extractor) and chat_structured (synthesis, narrative)
sites use the same wrapper and adopt in a follow-up.

Adds tests/platform/test_idempotent_llm.py (miss-calls-once, hit-replays,
different-messages-miss, disabled-not-cached). No schema change.

Subject: [PATCH 217/281] fix(platform): route pattern/synthesis/narrative LLM
 calls through idempotent wrapper (RFC-03 Phase 2)

Adopt idempotent_llm_call at the remaining five module-agent LLM sites:
pattern extraction (vr + malware, chat_json) and synthesis + narrative
(vr synthesis, malware synthesis, malware narrative, chat_structured).
Each called llm_client directly and double-paid the model API on ARQ
redelivery. Behavior is preserved -- the wrapper returns the same
LLMResponse and each caller re-parses .content unchanged.

Broaden honesty rule 43 agent_llm_chat_bypass to flag chat_json and
chat_structured (and the self._llm receiver the pattern extractor uses),
so every module-agent LLM call now routes through the platform wrapper or
is a finding. Baseline zero.

Subject: [PATCH 218/281] fix(platform): adopt idempotent wrapper at
 nday_researcher + close rule 43 alias blind spot (RFC-03 Phase 2)

An audit against the RFC-03 Phase 2 evidence table found
vr/agents/nday_researcher.py was still a direct llm_client bypass. It
aliases the client to a local (client = ServiceFactory().llm_client) then
calls client.chat, so both the earlier grep and honesty rule 43 (which
matched only .llm_client / ._llm receivers) missed it. NdayResearcher is
live via the vr nday workflow state, so it double-paid the model API on
ARQ redelivery like the other sites.

Route its per-turn chat through idempotent_llm_call (keyed by run_id +
turn, run_id forwarded for cost tracking). Broaden rule 43 to track local
names aliased to an llm client (client = <x>.llm_client) so a
client.chat() through an alias is now a finding; the honesty baseline
stays zero and is no longer a false negative.

Subject: [PATCH 219/281] refactor(platform): branch pool to platform/agents +
 FOR UPDATE fork cap (RFC-03 Phase 3)

Extract the branch-tree operations (fork / merge / promote / abandon /
pause / resume, plus spawn_strategy / list_active_by_strategy) into
platform/agents/branch_pool.py:BranchPool. The two module branch_manager
files were near-identical clones (only comment/docstring wording
differed); each is now a thin BranchManager(BranchPool) subclass binding
its record models and config namespace. BranchManagerError, BranchOpResult
and the case-state strip helpers move to platform; callers keep their
import surface via re-export, and the setup states import the strip
helpers from platform directly.

Adds the RFC-03 concurrency fix: fork() now takes a SELECT ... FOR UPDATE
on the parent investigation row before the cap count, so two concurrent
forks serialize on the cap check instead of both reading active<cap and
both inserting. The cap is read live via ModuleConfigReader(module_id);
no change to the cap value (vr default 24, malware 12).

Adds tests/platform/test_branch_pool.py: fork under cap, fork at cap
raises, concurrent forks respect the cap (the FOR UPDATE invariant),
promote abandons active siblings, pause/resume round trip. No schema
change.

-  promote   -- mark a branch as the authoritative one. Sibling ACTIVE

-  abandon   -- close a branch without promotion. Status → ABANDONED,

-  pause     -- temporarily stop driving the branch. Status → PAUSED.
-  resume    -- re-activate a PAUSED branch. Status → ACTIVE.

-This module owns ONLY the state transitions. The investigation_loop

-per cycle) is a follow-up -- schema + operations support it now.
-
-Per the no-overengineering rule: case-state merging on merge() is
-intentionally simple -- the CyberReasoningEngine.absorb() method is
-sequential per-decision; merging two static states is approximated by
-hypothesis union + rejected union + observable update. If a real
-investigation produces a merge that's lossy, refine then.
+The branch-tree transitions (fork / merge / promote / abandon / pause /
+resume) and the fork cap live once in
+``aila.platform.agents.branch_pool``. This module binds the VR record
+models and config namespace; ``BranchManagerError`` and ``BranchOpResult``
+are re-exported so existing callers keep their import surface.

+"""Platform branch pool (RFC-03 Phase 3).
+
+Generic branch-tree operations shared by every module. A module binds
+its branch + investigation record models and its config namespace; the
+platform owns the six branch transitions and the fork cap enforcement.
+
+Historical note (M3.R-5):
+
+Implements the 6 D-41 branch operations on an investigation's branch
+tree:
+
+  fork      -- spawn a new ACTIVE branch from a parent. New branch
+              inherits parent's case_state snapshot + optional persona
+              voice + fork_reason. Parent stays ACTIVE.
+  merge     -- consolidate two ACTIVE branches into a new ACTIVE branch.
+              Both originals → MERGED with merged_into_branch_id set.
+              New branch's case_state = absorb(absorb(empty, a), b).
+  promote   -- mark a branch as the authoritative one. Sibling ACTIVE
+              branches transition to ABANDONED with reason.
+  abandon   -- close a branch without promotion. Status → ABANDONED,
+              closed_at + closed_reason set.
+  pause     -- temporarily stop driving the branch. Status → PAUSED.
+  resume    -- re-activate a PAUSED branch. Status → ACTIVE.
+
+This module owns ONLY the state transitions. The investigation_loop
+state in workflow/states/ still drives turns; in v1 it drives only the
+primary branch. Multi-branch driving (loop iterates all ACTIVE branches
+per cycle) is a follow-up -- schema + operations support it now.
+
+Per the no-overengineering rule: case-state merging on merge() is
+intentionally simple -- the CyberReasoningEngine.absorb() method is
+sequential per-decision; merging two static states is approximated by
+hypothesis union + rejected union + observable update. If a real
+investigation produces a merge that's lossy, refine then.

Subject: [PATCH 220/281] refactor(platform): shared tool-execution primitives
 to platform/agents (RFC-03 Phase 4a)

Extract the three byte-identical primitives from the vr and malware tool
executors -- ToolExecutionResult, the tool-command parser, and the
contract-error classifier taxonomy -- into
platform/agents/tool_execution.py. Both executors import them; the local
copies are removed. Zero dispatch-flow change.

Implementation-review finding on the rest of RFC-03 Phase 4: the full
ToolExecutor dispatch consolidation is deferred to Phase 4b behind a
revised plan plus operator live smoke. The RFC premise that "malware
gains the pre-call hard-block" is a regression -- malware removed it by
design (retries must reach the bridge), so in any merged executor the
hard-block must be a per-module param (vr 3, malware disabled). The two
executors also carry ~630 lines of genuine module-specific behavior
(malware observation-store pipeline, vr audit_mcp index-id correction)
that must become optional hooks. Consolidating the hottest tool-call path
warrants that gate rather than a blind merge.

Adds tests/platform/test_tool_execution.py (parser edge cases, classifier
taxonomy, result defaults). No schema change.

The platform emit factory and malware's claim_verifier both construct
OutcomeDispatcher(knowledge=...) and call .dispatch(outcome_id), matching
the vr dispatcher. Malware's dispatcher exposed only
dispatch_outcome(*, outcome_id, investigation_id) with no knowledge param,
so the malware emit-dispatch and auto-promote paths raised TypeError
whenever an approved outcome reached them.

Conform malware's dispatcher: __init__ accepts knowledge (held for parity;
malware kinds write to target rows, not the knowledge store), and
dispatch(outcome_id) replaces dispatch_outcome -- investigation_id was
already resolved from the outcome row (the task passed ""), so the change
is behavior-preserving. Update the one caller (run_malware_outcome_dispatch).

The full OutcomeDispatcherBase consolidation + the dispatch TOCTOU fix
(SELECT FOR UPDATE + dispatch_status claim, needs a CLAIMED enum value and
an alembic migration) stays as RFC-03 Phase 6b: the two dispatchers share
only ~40% skeleton (vr has a state guard + 170-line post-dispatch side
effects; malware has neither) and the per-kind handlers have zero overlap,
so consolidating the outcome-finalization path warrants a revised plan
plus operator live smoke.

Adds tests/test_malware_outcome_dispatch_api.py.

Subject: [PATCH 222/281] refactor(platform): RFC-04 Phase 3 -- shared SSE
 transport hook

Extract the fetch + ReadableStream line-tail transport shared by the vr
and malware investigation-message SSE hooks into a generic
frontend/src/platform/hooks/useSSEStream.ts. The generic owns auth token
retrieval, the fetch connection, data-line splitting, connection status,
AbortController teardown, and optional reconnect with exponential backoff
(1s to 30s, abort-aware sleep). Module-specific concerns are callbacks:
buildUrl (computed at connect time so time-sensitive cursors stay fresh),
parseEvent (vr decodes a typed event envelope, malware reads bare summary
rows), and onMessage (each module merges into its own React Query cache).

Both module hooks become thin wrappers with no behavior change: vr keeps
its single-attempt, terminate-on-done stream (reconnect false) plus its
branch_id + since_iso params, malware keeps its since_id catch-up cursor,
reconnect loop, dedup, cold-cache fallback, and outcome-cache
invalidation. Net -147 lines across the two wrappers; the transport is
now single-sourced. useSSE (the app event-bus hook) is unchanged -- it
parses full SSE event frames into typed SSEEvent objects and serves a
different contract.

Adds a contract test for the generic transport (streamed data line to
parseEvent to onMessage, no-connect on a null url, non-data line
filtering, abort on unmount). Type-check and production build pass.

Subject: [PATCH 223/281] feat(honesty): RFC-05 rule 44 private_platform_import
 guardrail

Add honesty-audit rule 44 (private_platform_import): a module file that
imports a symbol from a platform private submodule
(from aila.platform.<pkg>._<priv> import Name) is a finding when the
public package aila.platform.<pkg> already re-exports Name -- via its
__init__ __all__ or a relative re-export binding. The module must import
from the public path so the platform stays free to move the private
implementation. A private symbol with no public counterpart is left
alone; the check resolves the public package's __init__.py by AST and
caches its public-name set.

This locks in RFC-05 concern (f): the tools._common / contracts._common
private-import migration is already complete in the tree (zero remaining
sites), so the rule fires zero findings today and prevents a silent
regression. The one surviving module private import
(mcp.adapters._shared to enrich_strings_with_decodes) has no public
re-export and is correctly not flagged.

Rule wired into the module-file dispatch block next to the other
import-boundary checks. Adds seven rule tests (re-export-binding and
__all__-member fire paths; public-path, no-counterpart, platform-scope,
missing-init, and whitelist negatives). Full honesty audit stays green.

Subject: [PATCH 224/281] refactor(platform): RFC-05 (e) IntelServiceProtocol
 via platform runtime

Remove vr's cross-module reach into the vulnerability runtime for CVE
intel. vr's cve_intel_resolver called
platform.runtime.require_module("vulnerability") then
getattr(vuln_runtime, "intel") -- a module-to-module coupling that
welded vr to vulnerability (vr could not ship without it, and
vulnerability could not restructure its intel service without breaking
vr).

Invert the direction through the platform:
- New platform/services/intel_service.py declares IntelServiceProtocol
  (the fetch_cve_intel method contract; the knowledge return stays
  module-owned and is consumed structurally).
- PlatformRuntime gains an intel_service slot.
- The builder collects it via _collect_intel_service, which reads each
  module runtime's provides_intel_service() (platform-introspects-module
  is legal; module-reaches-peer is not). First non-None wins; absence is
  normal and yields None.
- VulnerabilityRuntime publishes its IntelService through
  provides_intel_service().
- vr reads platform.runtime.intel_service and never names the provider.

Behavior-preserving: the same IntelService instance resolves the same
CVEs; when no module publishes one (worker started --modules vr only)
vr degrades through its existing status=error fallback exactly as
before. cve_intel_resolver.py now contains no require_module and no
getattr(vuln_runtime), satisfying the RFC-05 (e) acceptance criterion.

Tests: _collect_intel_service (published / absent / method-missing /
none-returning / empty) and the resolver reading the platform slot
(found + provider-absent). Full honesty audit stays green.

Subject: [PATCH 225/281] refactor(platform): RFC-05 (b) parameterize MCP
 bridges by module_id

The three platform MCP bridge tools (AuditMcpBridgeTool, IDABridgeTool,
AndroidMcpBridgeTool) hard-coded a vr-prefixed tool name as a class
attribute (name = "vr.audit_mcp_bridge" etc.) and read their base URL
from a hard-coded "vr" config namespace. Both weld a platform-owned
bridge to one module.

Derive both from a constructor module_id (keyword-only, default "vr"):
- self.name = f"{module_id}.<suffix>_bridge" replaces the class literal.
- _resolve_base_url reads ConfigRegistry().get(self.module_id, <key>).

The default "vr" keeps every existing caller byte-identical: the tool
names stay "vr.audit_mcp_bridge" / "vr.ida_bridge" /
"vr.android_mcp_bridge" and the config namespace stays "vr", so there
are no callsite changes and no behavior change. A module that wants its
own namespace and tool-name prefix passes module_id explicitly (a
deliberate follow-up, not forced here).

Adds honesty rule 45 (module_prefix_in_platform_tool_name): a
class-level or self.name string literal under platform/mcp/bridges/ that
starts with a known module id is a finding; the f-string form is clean.
Rule tests (class-level, annotated, self.name fire paths; f-string,
non-bridge, non-prefixed negatives) plus a bridge test (default
preserves vr names, explicit module_id derives the name). Full honesty
audit stays green.

Subject: [PATCH 226/281] refactor(platform): RFC-05 (c) drop dead domain-event
 vocabulary

platform/events/domain_events.py carried a vulnerability-domain event
vocabulary -- ScanStarted, ScanCompleted, FindingUpserted, FindingResolved
and their five payload models -- that was never emitted or subscribed
anywhere. The only references were the re-exports in events/__init__.py
and two ReportService docstrings that claimed emission the method bodies
never performed.

Delete the four dead event classes and five dead payloads, drop them
from events/__init__.py, and correct the ReportService docstrings to
describe what the methods actually do (persist via PersistContract, no
event emission). The platform keeps only generic infrastructure events:
system lifecycle, config change, assessment lifecycle, and LLM-call
accounting.

Adds honesty rule 46 (platform_owns_event_vocabulary): an event class
under platform/events/ whose class name or event_type literal carries a
module-domain token (scan, finding, investigation, or a module id) is a
finding. A module that needs to publish a workflow or entity event
declares it in its own package; the platform does not host domain
vocabulary. Rule tests cover class-name and event_type fire paths plus
infrastructure-event, assessment, and non-events-file negatives. No new
speculative event classes were added -- nothing emits them yet, so
adding them would only recreate dead vocabulary. Full honesty audit
stays green.

Subject: [PATCH 227/281] refactor(platform): RFC-05 Phase 6 -- platform owns
 task/cursor reaping

Reconciliation, reenqueue, and reaping of platform-owned task state are
platform responsibilities, not custom module code. This moves the last
module-side raw SQL against taskrecord / workflow_state_cursor into the
platform and makes the zombie/cursor reaper a single platform-owned
sweep across every track.

- New platform reaper cursor_reaper.reap_zombie_tasks_and_cursors runs
  the four coupled maintenance statements (cancel stale-running tasks;
  purge orphan / terminal / __succeeded__ cursors) in one transaction.
  It now reaps EVERY track, not just vr -- a stale-running task is a
  zombie regardless of which module owns it. It is wired into the
  platform worker reaper cron next to sweep_orphan_crashed_cursors, with
  env-driven thresholds (PLATFORM_REAPER_ZOMBIE_HEARTBEAT_MIN default 10,
  PLATFORM_REAPER_CURSOR_BATCH_CAP default 5000 -- the historical vr
  values).
- vr/masvs/parent_reconciler drops its private reaper step and function;
  it keeps only the masvs-domain parent/child orchestration. The two
  now-dead vr config fields (zombie_task_heartbeat_min,
  cursor_cleanup_batch) are removed.
- investigation_lifecycle.purge_investigation_cursors centralizes the
  per-investigation cursor wipe; the malware reset handler and the
  platform reenqueue path both call it (reenqueue de-duplicated onto it).
- pdf_report's active-runtime query moves to
  platform/tasks/runtime_stats.active_task_runtime_seconds, removing the
  module's psycopg import and raw taskrecord SQL.

Adds honesty rule 47 (raw_sql_platform_tables): a module string constant
with a FROM|INTO|UPDATE|JOIN clause against taskrecord /
workflow_state_cursor is a finding, so this cannot regress. Rule tests
cover DELETE/SELECT/concatenated fire paths plus module-owned-table,
prose, and platform-file negatives. Full honesty audit stays green.

The reaper trigger relocation and the all-track extension change worker
cron behavior and need a live worker-cron smoke at merge.

-    """Reap zombie tasks and stale workflow_state_cursor rows.
-
-    Two coupled failure modes leave the queue silently jammed (D-283):
-
-    1. Zombie task: ``taskrecord.status='running'`` with
-       ``heartbeat_at`` older than ``VR_ZOMBIE_TASK_HEARTBEAT_MIN``
-       (default 10 min). Caused by worker crash mid-task,
-       OmniRoute retry-loop wedging the worker for hours, or any
-       hang the worker can't recover from. The TaskRecord row
-       stays at ``running`` indefinitely, and dedup at
-       queue.py:132-140 then refuses to re-enqueue the same
-       investigation+branch payload because there's still an
-       "in-flight" task -- but no worker is actually working it.
-
-    2. Stale workflow_state_cursor: rows persist after the owning
-       task terminates abnormally. When a fresh task for the same
-       run_id starts, the workflow engine sees a stale cursor in
-       a transient state (``investigation_loop`` etc.) and
-       silently blocks. Observed live: 19 fresh tasks at 01:35:01
-       all stuck at first heartbeat for 10+ min because of 169
-       leftover cursors from a prior crash window.
-
-    This sweep:
-      (a) marks any vr-track task at ``status=running`` with
-          stale heartbeat as ``cancelled`` (frees dedup slot),
-      (b) deletes orphan cursors (no matching TaskRecord at all),
-      (c) deletes cursors whose TaskRecord is already terminal
-          (cancelled / done / failed / dead_letter),
-      (d) deletes cursors at the success terminal state
-          ``__succeeded__`` regardless of TaskRecord linkage
-          (the workflow engine itself never reads these again).
-
-    Active in-flight tasks (status IN queued/running/waiting with
-    fresh heartbeat) are left strictly alone. Only the explicitly
-    dead state gets reaped.
-
-    Returns ``{zombies_cancelled, cursors_purged}``.
-
-    fix §42 -- Single-session-scope assumption.
-    --------------------------------------------------
-    The function issues four UPDATE/DELETE statements:
-      (1) UPDATE taskrecord SET status='cancelled' WHERE stale heartbeat
-      (2) DELETE workflow_state_cursor WHERE no matching taskrecord
-      (3) DELETE workflow_state_cursor WHERE taskrecord is terminal
-      (4) DELETE workflow_state_cursor WHERE current_state='__succeeded__'
-
-    Steps 1 → 3 are intentionally ordered so step 3 sees the rows step 1
-    just marked ``cancelled`` (the cancelled rows then become eligible
-    for cursor deletion in the same tick). This is correct ONLY when
-    all four statements run inside the SAME session/transaction, so
-    step 3's ``JOIN taskrecord`` sees step 1's uncommitted update --
-    Postgres' default READ COMMITTED visibility for statements within a
-    single transaction makes this work. If the caller ever split this
-    helper across two sessions, step 3 would miss the just-cancelled
-    rows and they'd survive until the next tick.
-
-    The assertion below enforces the assumption at function entry: the
-    caller MUST hand us a session that is already in a transaction.
-    Documentation-only change otherwise -- no statement reordering, no
-    new commits.
-    """
-
-    # fix §42 -- single-session-scope invariant. The caller's UnitOfWork

Subject: [PATCH 228/281] refactor(platform): RFC-05 (d) module-declared
 reasoning registries

The platform contract hardcoded a closed Literal of nine module-domain
strategy families and a table of four domain profiles naming forensics
and vulnerability domains. Both are module vocabulary the platform
should not own.

- ReasoningStrategyFamily changes from a Literal to str; strategy
  families are runtime-validated by a platform StrategyRegistry (seeded
  with the platform-owned "generic" family only). Adds
  ReasoningStrategyDeclaration.
- New StrategyRegistry + DomainProfileRegistry in services/reasoning.py.
  _DOMAIN_PROFILES is removed; CyberReasoningEngine.resolve_domain_profile
  reads the DomainProfileRegistry, keeping the config-override tier and
  the graceful generic fallback for unregistered domains unchanged.
- ModuleProtocol gains reasoning_strategies() and
  reasoning_domain_profiles() (default empty). The platform builder
  collects them from every module at load into the registries.
- vr declares vulnerability_research / web_pentest / mobile_reverse;
  forensics declares filesystem_triage / persistence_hunt /
  memory_forensics / network_forensics / malware_static + the forensics
  profile. Profile values are reproduced verbatim from the former
  platform table, so resolution is behavior-preserving; malware carries
  no profile and uses generic as before.

Tests cover the registries (seed/register/resolve/raise/clear), the
module declarations, and that resolve_domain_profile returns the legacy
values for registered domains and generic for the rest. Full honesty
audit green.

The Literal-to-str change moves strategy-family validation from parse
time to the registry, and profile resolution now depends on module
registration at load; a reasoning smoke on a live vr/forensics
investigation is warranted at merge.

Subject: [PATCH 229/281] test(vr): fix stale imports after RFC-03 platform
 extractions

Two vr test modules failed collection because they imported symbols that
RFC-03 moved to the platform:
- test_vr_mcp_adapters imported _parse_command from
  vr.agents.tool_executor; the parser is now
  platform.agents.tool_execution.parse_command, re-exported as
  parse_command from the vr module.
- test_vr_branch_manager imported the case-state merge helpers (_decode,
  _encode, _has_contract, _merge_case_states, merge_hypotheses,
  merge_rejected) from vr.agents.branch_manager; they now live in
  platform.agents.branch_pool.

Redirect both imports. Restores pytest collection of the full suite;
77 tests pass. No production code change.

systems, topology, tags, executive, findings-workflow, and the scheduled
risk-PDF task, plus a hardcoded TRACK_VULNERABILITY constant and a
finding-state vocabulary defined in the api schema layer.

- ModuleRegistry.first_with/all_with resolve a module by capability. The
  14 require("vulnerability") sites now resolve by the method they call
  and degrade to a graceful skip or 503 when no registered module
  answers, so the boundary layer names no module.
- ModuleProtocol.scan_submission_track() lets a module declare the ARQ
  track a POST /analyze scan runs on. scans.py resolves it instead of
  importing TRACK_VULNERABILITY, which is removed from api/constants.
- The generic finding-triage lifecycle (new, investigating, mitigated,
  verified, closed) moves from api/schemas/endpoints.py into a platform
  contract at platform/contracts/finding_states.py. findings-workflow
  reads the platform base and merges module workflow_definitions on top.
  The FindingTransitionRequest state validator moves out of the Pydantic
  model into the handler, which validates against the resolved machine.
- honesty rule 48 platform_names_module flags a boundary-guarded file
  (api/, platform/, storage/) that names a feature module in a
  .require(...) / .require_module(...) call.

require("<module>") and from aila.modules.<x> in platform+api: 0.
TRACK_VULNERABILITY: 0.

Subject: [PATCH 231/281] fix(platform): RFC-03 Phase 6b -- close outcome
 dispatch TOCTOU with a platform claim

Two workers could each read the same accepted outcome as dispatchable and
both run its handler, double-shipping the artifact (finding, child
investigation, report). The malware dispatcher had no state gate at all,
widening its window.

- platform/services/outcome_dispatch.py: claim_outcome_for_dispatch opens
  a unit of work, selects the outcome FOR UPDATE, runs an optional domain
  guard, and flips PENDING -> CLAIMED in the same transaction. A
  concurrent dispatcher's FOR UPDATE blocks until the claim commits, then
  observes CLAIMED and backs off, so exactly one caller proceeds.
- OutcomeDispatchStatus gains CLAIMED. The column is varchar(16), so no
  migration is required.
- vr and malware outcome dispatchers claim before running any handler. vr
  supplies its state == approved gate as the claim guard (behavior
  preserved); malware supplies a kind guard that refuses the claim for
  outcomes with no handler so they stay pending.
- Stale CLAIMED rows left by a dispatcher that crashed post-claim are
  reset by the RFC-07 resilience reaper (follow-on).

Tests: 5 claim tests including a concurrent-race single-winner assertion;
23 vr and 21 malware existing dispatcher tests remain green.

Subject: [PATCH 232/281] test(vr): characterization net for ToolExecutor
 pre-dispatch gating (RFC-03 Phase 4b prep)

The two module ToolExecutors have zero unit coverage of execute(); RFC-03
Phase 4b will lift ~750 shared lines into a platform ToolExecutorBase. This
adds a golden-master net for the VR pre-dispatch gating so that extraction
can be proven behavior-preserving on the shared paths:

- malformed command -> error result, empty server/tool, bridge NOT called
- tool without a server prefix -> error result, bridge NOT called
- unknown tool with no adapter -> error result, bridge NOT called

Each asserts the ToolExecutionResult contract and that no fake bridge
forward() was awaited. The divergent hard-block, circuit-breaker, and
success+observation paths need deep message-history seeding and remain
covered by verbatim lift plus live smoke at merge.

Subject: [PATCH 233/281] test(malware): characterization net for ToolExecutor
 pre-dispatch gating (RFC-03 Phase 4b prep)

Golden-master coverage of the malware ToolExecutor.execute() gating so the
Phase 4b platform extraction is provably behavior-preserving on the shared
and malware-divergent paths:

- malformed command -> error result, bridge NOT called
- _AGENT_ALLOWED_SERVERS allowlist rejects a non-allowed server (audit_mcp)
  before the adapter lookup, bridge NOT called (the malware-divergent path
  Phase 4b turns into an allowed_servers constructor input)
- unknown ida_headless tool with no adapter -> error result, bridge NOT called

Subject: [PATCH 234/281] feat(platform): RFC-09 step 0 -- file-backed prompt
 registry

Both module researchers carried a byte-identical _cached_read_prompt +
_load_prompt pair differing only in the fallback base filename and the
error class. This lifts the single file-backed resolution path into a
platform PromptRegistry so no module reimplements it, and gives RFC-09's
later steps (DB overrides, immutable versions, release aliases,
per-investigation pins) one place to grow.

- platform/prompts/registry.py: PromptRegistry(prompt_dir, fallback_base)
  .load(strategy_family, persona_voice) resolves system_<strategy-leaf>.md
  (falling back to the module base filename), prepending persona_<voice>.md
  when present. Behavior-identical to the prior module logic; file-backed
  only, no database and no versioning at this step.
- vr and malware researchers delegate _load_prompt to a module-level
  registry, translating PromptNotFoundError into their own error type. The
  duplicated _cached_read_prompt and its now-unused functools import are
  removed from both.

Tests: 8 unit tests (strategy-specific base, fallback, dotted-leaf
extraction, missing-prompt error, persona prepend, case-insensitive
persona filename, missing persona, malware fallback name). Verified both
modules resolve their real base prompts unchanged (vr 33728 bytes, malware
130247 bytes).

Subject: [PATCH 235/281] feat(platform): RFC-09 step 1 -- tag LLM cost records
 with prompt content hash

Each LLM cost record now carries the sha256 of the resolved system prompt
template that produced the call, so cost (and later quality) is attributable
to the exact prompt content. This is the observability foundation the later
RFC-09 steps (DB overrides, versions, aliases) build on.

- correlation.py: CorrelationContext gains prompt_content_hash;
  correlation_scope accepts it; current_prompt_content_hash() reads it.
  Threaded through the same ContextVar that already carries the
  investigation/branch/turn join keys, so no call signatures change.
- cost_record.py: LLMCostRecord gains a nullable, indexed prompt_content_hash
  column. Migration 086 adds it (IF NOT EXISTS guarded); create_all keeps
  tests and fresh installs in sync.
- cost.py: persist_cost_record reads current_prompt_content_hash() and tags
  the record.
- vr and malware researchers compute sha256 of the resolved system prompt and
  pass it into correlation_scope for the turn.

The semver prompt_version column is intentionally deferred to step 4, where
immutable versions actually exist; content_hash is the stable identity now.

Tests: 2 unit tests (tagged from correlation; None without a scope).

+"""086 -- add prompt_content_hash to llm_cost_records (RFC-09 step 1).
+
+Tags each LLM cost record with the sha256 of the resolved system prompt
+template that produced the call, so cost (and later quality) is attributable
+to the exact prompt content. Nullable: calls outside an agent turn (scoring,
+report generation) leave it unset. The agent turn loop sets it through the
+correlation ContextVar (``aila.platform.llm.correlation``) that the
+cost-record writer reads. The SQLModel model is updated in the same commit so
+``create_all`` (tests, fresh installs) matches the migrated schema.
+
+Guarded with IF NOT EXISTS so a re-run, or a fresh database that already
+carries the column, is a no-op.

Subject: [PATCH 236/281] feat(platform): RFC-09 step 4 -- immutable prompt
 version + alias store

The DB-backed versioning layer RFC-09 needs for deploy/rollback without a
code release: immutable content-hashed prompt versions, mutable release
aliases (candidate/staging/production), and an append-only alias-change
audit log.

- version_models.py: prompt_versions (unique per key+version and
  key+content_hash), prompt_aliases (one pointer per key+alias),
  prompt_alias_changes (audit). Registered on SQLModel.metadata via
  db_models re-import. Migration 087 creates them (IF NOT EXISTS guarded);
  create_all keeps tests and fresh installs in sync.
- version_store.py: PromptVersionStore.register (immutable,
  content-hash-deduplicated, monotonic 1.0.N versions), resolve (by
  explicit version or by alias pointer, None -> caller falls back to the
  file base prompt), set_alias (audited pointer flip = deploy/rollback,
  raises PromptVersionNotFoundError for an unknown version).

This is the store layer. Wiring the file-backed PromptRegistry to resolve
through it and pinning the resolved version per investigation at setup
(steps 2-3) are the follow-on increments; both need the sync _load_prompt
path to become async, so they land as a separate focused change.

Tests: 5 unit tests (content-hash idempotent register, monotonic
versioning, resolve by version/alias/miss, alias flip + audit log,
missing-version guard).

Subject: [PATCH 237/281] fix(frontend): render the 'claimed' outcome dispatch
 status

Phase 6b (5247edc) added OutcomeDispatchStatus.CLAIMED on the backend and
the outcome API serializes it, so a response can carry "claimed" while a
dispatch handler runs. Both module frontend OutcomeDispatchStatus unions
omitted the value, so the Record<OutcomeDispatchStatus, ...> color and
label maps had no key for it. On the malware outcome detail page the maps
were indexed with no fallback, rendering a blank pip and empty label for a
claimed row; TypeScript could not catch it because the value arrives via an
untyped API cast.

- vr + malware types.ts: add "claimed" to the OutcomeDispatchStatus union.
  This makes the type checker enforce that every dispatch-status map covers
  it.
- vr + malware InvestigationDetailPage dispatchColor: claimed -> "info"
  (transient, non-terminal).
- malware OutcomeDetailPage DISPATCH_COLOR: claimed -> var(--status-running);
  DISPATCH_LABEL: claimed -> "Dispatching". Add a defensive fallback at the
  index site so any unmapped status degrades gracefully.

type-check clean for @aila/vr-frontend and @aila/malware-frontend.

Subject: [PATCH 238/281] fix(platform): zombie reaper must not cancel
 never-beating tasks

The platform zombie reaper (reap_zombie_tasks_and_cursors) cancelled any
running task whose COALESCE(heartbeat_at, started_at) was older than the
threshold, which treats a NULL heartbeat as evidence of death. That is
wrong for single-shot tool tasks: run_function_ranking and deep_audit run
for many minutes with heartbeat_at NULL while healthily awaiting one HTTP
response, so a >10-minute audit run was cancelled mid-flight. This is the
exact false positive that _sweep_orphan_running_tasks already guards with
reap_null_heartbeat=False; the reaper reintroduced it for every track when
the reaping moved to the platform cron.

A zombie is a task that reported a heartbeat and then went silent. The
cancel predicate is now `heartbeat_at IS NOT NULL AND heartbeat_at <
threshold`. A task that never beat is left alone; its lifecycle is bounded
by the ARQ job timeout. The change is track-agnostic (no module naming),
so it keeps the platform boundary the reaping move established.

Tests: tests/platform/test_cursor_reaper_zombie.py -- stale-beat reaped,
null-heartbeat exempt (the fix), fresh-beat exempt.

Subject: [PATCH 239/281] fix(platform): self-heal a stranded outcome dispatch
 claim

Phase 6b closed the dispatch double-ship TOCTOU by flipping an outcome to
CLAIMED under FOR UPDATE, but a dispatcher that wins the claim then crashes
before writing the terminal DISPATCHED/FAILED status stranded the row at
CLAIMED forever: every retry saw CLAIMED and skipped, so the outcome never
dispatched. That traded double-ship safety for a new lost-dispatch failure
mode with no recovery path.

Add claimed_at to the outcome record. The claim now stamps it and treats a
CLAIMED row as a live claim only while claimed_at is within a reclaim
window (900s, far longer than any real dispatch). A CLAIMED row older than
the window is a stranded claim and the next dispatch attempt reclaims it,
so a crashed dispatch self-heals without a separate reaper. DISPATCHED
stays terminal and is never reclaimed. The claim also splits the skip
reasons that used to collapse into one: DISPATCHED -> "already_dispatched",
a fresh CLAIMED -> "claim_in_progress" (both surfaced in logs/results only;
no caller branches on the string).

- OutcomeRecordBase: nullable claimed_at column; migration 088 alters
  vr_investigation_outcomes and malware_investigation_outcomes (create_all
  keeps tests and fresh installs in sync).
- claim_outcome_for_dispatch: reclaim-window check + claimed_at stamp.

Tests: 3 new (stale claim reclaimed, fresh claim held, dispatched
terminal); existing claim + 26 module dispatcher tests still green.

Subject: [PATCH 240/281] fix(platform): prompt version suffix must not reuse
 an archived number

PromptVersionStore.register derived the next version suffix from the count
of surviving rows (len(prior)), so archiving an old version made a later
register emit a suffix that collides with an existing row and violates the
key+version unique constraint. The next suffix is now one past the highest
suffix ever issued for the key, not the row count, so decommissioning an
old version never reuses (or collides with) an already-issued number.

Test: register three, archive the oldest, register a fourth -- it is
1.0.3, not the count-based 1.0.2 that would collide with the survivor.

Subject: [PATCH 241/281] feat(platform): tag audit seals with the prompt
 content hash (RFC-09 step 1)

Step 1 tags each LLM call with the sha256 of the resolved system prompt so
cost and evidence are attributable to the exact prompt content. 086 added
that tag to llm_cost_records; the audit seal -- the HMAC chain-of-custody
record -- was left untagged, so the seal could not be tied to a prompt
version. Tag it from the same correlation ContextVar the cost writer reads.

- AuditSealRecord: nullable indexed prompt_content_hash column.
- seal step: reads current_prompt_content_hash() and stamps the record.
- migration 089 alters auditsealrecord (create_all keeps tests and fresh
  installs in sync).

Tests: seal carries the hash when a correlation scope is set; NULL for a
call outside an agent turn.

Subject: [PATCH 242/281] refactor(platform): give ProgressStream._KEY_FMT a
 single reader

RFC-05 Phase 6 intended the task-progress stream-key format to stay
private to ProgressStream, with callers routing through a public method.
That half never shipped: platform/workflows/log.py and, worse, the
forensics module emitter read ProgressStream._KEY_FMT directly to build a
custom XADD, a module reaching into a platform class's private attribute.

Add ProgressStream.stream_key(task_id), the single public accessor for the
key. emit / catchup / stream_events and both external XADD sites now route
through it, so _KEY_FMT has exactly one reader. The forensics module no
longer touches any platform private (it still uses the public get_redis
service). Behavior is unchanged -- the key value is identical.

- whitelist stream_key against do_nothing_wrapper: it is the deliberate
  encapsulation point; inlining it reinstates the private-attr coupling.
- fix a stale assertion in the same test file (progress.__all__ already
  carried MAX_STREAM_LIFETIME_S).

Tests: stream_key accessor unit test; existing emit/catchup/stream key
assertions still green.

Subject: [PATCH 243/281] fix(platform): arq_purge redis-url fallback imported
 a nonexistent module

purge_arq_jobs_for_investigation resolves the Redis URL as param -> env ->
ConfigRegistry. The ConfigRegistry branch imported it from
aila.platform.services.config_registry, which does not exist (the class is
aila.storage.registry.ConfigRegistry, as every other caller imports it).
The ImportError was caught by a silent `except`, so redis_url fell to None
and the purge returned a zero result without touching Redis whenever
AILA_PLATFORM_REDIS_URL was not exported (start.sh does not export it). Every
terminal / pause / cap-sweep purge routed through this platform primitive
silently no-op'd, leaving stale queued ARQ jobs. The workflow STATUS_LOCKED
guard prevented the stale jobs from causing data corruption, so the bug was
invisible.

Import ConfigRegistry from aila.storage.registry and log the fallback
failure instead of swallowing it.

Tests: url resolves through ConfigRegistry when env is unset and reaches the
Redis client; an empty config yields a clean zero result with no client.

Subject: [PATCH 244/281] fix(forensics): route the resolver LLM call through
 the idempotency cache

ResolverAgent._attempt_resolution issued a direct llm_client.chat with no
request key. resolve() is driven by the forensics resolution workflow
state under the ARQ-backed DurableStateMachine, so a worker crash + ARQ
redelivery re-paid the model for the same question -- the exact double-pay
RFC-03 Phase 2 closed at the vr/malware agent sites. This module agents/
call was never adopted.

Route the call through platform idempotent_llm_call (method="chat") keyed on
project_id + the full messages, so a redelivered resolution replays the
cached answer instead of calling the model again.

Tests: an identical resolution calls the model once (second served from
cache); a distinct question calls it again.

Subject: [PATCH 245/281] refactor(platform): extract shared ToolExecutor
 helpers to a platform base

RFC-03 Phase 4b, helper-extraction step. The vr and malware tool executors
carried byte-identical copies of nine helpers -- tool-result persistence,
the repeat-failure / error-class / malformed circuit-breaker counters, the
read-tool resolver, and the observable-merge -- differing only in the
module-specific message / branch record types.

New platform/agents/tool_executor.py::ToolExecutorHelpersBase owns those
nine helpers, parameterized on self._message_model / self._branch_model
(and _MALFORMED_TOOL_RUN_MARKER / _MAX_OBSERVABLES as shared constants).
Both module ToolExecutors now subclass it, set the two record types in
__init__, and drop their local copies. The divergent parts stay module
side: the execute() dispatch loop, the survey-streak hint text,
pivot-history parsing, VR index-correction, and malware observation
recording.

Behavior-preserving: the lifted helpers differed only by the record type
that is now injected. The execute() merged dispatch itself (domain
divergent) remains module-side pending its own change.

Verified: compile + ruff + honesty clean; the vr and malware ToolExecutor
characterization nets (6), outcome dispatcher tests (26), and the full
agents test directory pass; both executors resolve the inherited helpers at
runtime.

+"""Shared ToolExecutor helper base (RFC-03 Phase 4b, helper extraction).

+helpers -- differing only in the module-specific message / branch record
+types. This base owns that shared behavior; a subclass sets

Subject: [PATCH 246/281] test(agents): direct coverage of extracted
 ToolExecutor helpers

The ToolExecutor characterization nets covered only the pre-dispatch
gating paths. The nine helpers just lifted to ToolExecutorHelpersBase had
no direct test, so the extraction rested on structural checks alone. Add
golden-master tests that exercise the lifted helpers through both module
injections:

- _count_prior_failures: pairs a tool_call with a same-args error and
  counts repeats; a different-args pair does not count (vr + malware).
- _count_total_malformed: counts malformed-marker errors across the
  window, ignoring a non-malformed error (vr).
- _persist_result_and_observables: one call writes the result message AND
  merges the observables delta into the branch case_state (vr + malware).
- _apply_observables_delta: merges a delta and caps at _MAX_OBSERVABLES
  while always keeping _directive.* keys (vr, pure helper).

These pin the circuit-breaker and result-persistence behavior against the
injected record types, strengthening the net for the deferred execute()
merged-dispatch step. Agents suite: 12 pass (was 6).

Subject: [PATCH 247/281] feat(agents): resolve prompts through the version
 store (RFC-09)

The prompt version store shipped without a consumer -- nothing resolved
through it, so a registered version could never influence a turn. Wire it
into both researchers' _load_prompt: resolve the "production" alias for a
{module}/{strategy}/{persona} key first, and fall back to the file registry
when no version is deployed. The file is the baseline; the store is the
deploy override, so a store fault degrades to the file rather than blocking
a turn. An operator can now register a new prompt body and flip the
production alias to deploy a prompt change without a code release, which is
the point of RFC-09 versioning.

_load_prompt becomes async (its single caller per module is already async);
the file-loading unit tests are converted to async and take the test_db
fixture so the store resolve is deterministic.

Behavior-preserving with an empty store: resolve returns None, the file is
loaded exactly as before.

Tests: registered+aliased production version overrides the file; empty
store falls back to the file (vr). 103 researcher/prompt/agent tests pass.

Subject: [PATCH 248/281] feat(api): admin prompt-version deploy surface
 (RFC-09)

The version store and the turn-time resolve path were in place, but there
was no operator way to get a version into the store or flip a release
alias, so the deploy mechanism could not be exercised without direct store
calls. Add a god-tier admin router that closes the loop:

    POST /admin/prompts/versions       register an immutable version
    GET  /admin/prompts/versions?key=  list registered versions
    PUT  /admin/prompts/aliases        point an alias at a version (deploy)
    GET  /admin/prompts/aliases?key=   list alias pointers

An operator now registers a new prompt body and flips the "production"
alias; the researchers resolve that alias on the next turn (already wired),
so a prompt change deploys without a code release -- the RFC-09 goal. All
endpoints require god-tier admin (team_id=None) since prompt versions are
platform-wide; every endpoint is rate-limited. Unknown-version alias flips
return 404.

Adds PromptVersionStore.list_versions / list_aliases for the read surface.

Tests: register + content-hash dedup + list; alias deploy + rollback;
unknown-version 404; reader-role 403.

Subject: [PATCH 249/281] refactor(agents): merge ToolExecutor.execute into
 platform base via hooks

Consolidate the near-identical per-turn tool dispatch loop (vr 497L,
malware 466L) into ToolExecutorHelpersBase.execute on the platform base.
The seven behavioral divergences become override hooks:

- _pre_dispatch_correct_args: dispatch-arg correction (vr audit_mcp index)
- _augment_tool_error: domain error hints (vr macro search)
- _pivot_alternatives: circuit-breaker alternative tool calls
- _post_dispatch: post-call side effects (malware observation recording)
- _resolve_bridge_base_url: auto-steering bridge URL source

Config attrs carry the rest: _AGENT_ALLOWED_SERVERS (malware ida_headless
allowlist), _HARD_BLOCK_REPEAT_LIMIT (vr pre-call hard block, malware
None), _TOOLRUN_EXAMPLE_JSON, _TOOLRUN_ACTIONS. The shared skeleton
(parse, circuit-breaker texts, persist, auto-steering post) is identical
between the two former copies and now lives once.

Both module executors drop their execute copy and keep only their domain
helpers (vr index-id cache, malware observation store). Points
test_vr_mcp_adapters at the platform parse_command home; removes dead
per-module success-status / malformed-marker / cmd-size constants now
owned by the base. Net -374 lines.

Subject: [PATCH 250/281] refactor(agents): lift shared turn-runner helpers to
 platform

Four byte-identical helper functions were duplicated in the vr and
malware turn runners: the case-state JSON codec (decode_case_state,
encode_case_state), terminal live-hypothesis auto-resolution
(auto_resolve_live_on_terminal), and outcome-confidence coercion
(to_outcome_confidence). They depend only on platform contract types.

Consolidate into aila.platform.agents.turn_helpers with public names;
both researchers import them and drop their local copies. This removes
~69 lines of duplication per module and is a prerequisite for the
Phase 7 run_turn consolidation (the base run_turn can call these as
platform names instead of per-module module-level functions).

Adds tests/platform/agents/test_turn_helpers.py (codec round-trip,
degrade-to-empty on bad input, confidence mapping, auto-resolve move +
dedup semantics). Repoints the vr researcher test at the platform home.

Subject: [PATCH 251/281] feat(eval): eval-gated prompt-version promotion
 runner (RFC-08)

First increment of eval-gated self-improvement: an EvalRunner that
scores a candidate prompt version against a stored benchmark and gates
the production-alias flip through the shipped PromptVersionStore.

- eval/models.py: EvalBenchmarkRecord (frozen scored cases per key) and
  EvalRunRecord (candidate/baseline versions, report, pass|fail verdict).
- eval/runner.py: EvalRunner.run resolves the current production baseline,
  scores per-version case bundles via the shipped metrics (ece,
  precision_recall_per_kind, faithfulness), applies EvalReport.beats() as
  the strict gate, and flips the production alias only when the candidate
  passes AND auto_promote is set. First-ever eval for a key auto-passes
  with a warning (no baseline). Empty candidate bundle is rejected rather
  than scored as a spurious pass.
- admin_eval.py: god-tier-admin router -- POST /admin/eval/benchmarks,
  POST /admin/eval/runs, GET /admin/eval/runs, mirroring admin_prompts.
- migration 090 creates eval_benchmarks + eval_runs (eval_-prefixed
  identifiers, (key, created_at) indexes). Down-revision 089.

Scores pre-supplied case outcomes; record-replay ingestion is a later
increment (documented in the runner docstring). Tests: 5 runner cases
(promote-on-pass, fail-leaves-alias, missing-benchmark, first-eval
auto-pass, pass-but-no-auto-promote); 22 pass with the eval + prompt
suites combined.

+"""090 -- eval harness tables (RFC-08 step 1).
+
+Creates the two tables backing the eval runner:
+
+- ``eval_benchmarks`` -- a named benchmark of pre-scored ``CaseOutcome``
+  cases (predicted_verdict / verified_verdict / confidence per case,
+  per version) plus a ``key`` naming the prompt those cases score.
+- ``eval_runs`` -- one scoring event: which candidate prompt version was
+  scored against which benchmark, which production version served as
+  the baseline (nullable for a first-ever eval), the serialized
+  ``EvalReport`` bundle, and the 'pass' / 'fail' verdict.
+
+Columns match the SQLModel definitions in platform/eval/models.py so
+``create_all`` (tests, fresh installs) matches the migrated schema.
+Constraint and index names are prefixed ``eval_`` because Postgres
+constraint names are database-scoped, not table-scoped -- unprefixed
+names would collide with other modules over time. Guarded with
+``IF NOT EXISTS`` so a re-run, or a fresh database that already carries
+the tables, is a no-op.

+"""Eval runner: score a candidate prompt version and gate promotion (RFC-08).
+
+Scope of THIS increment
+-----------------------
+The runner scores a candidate against a benchmark of ``CaseOutcome`` rows
+that are ALREADY resolved (predicted_verdict / verified_verdict /
+confidence per case, per outcome_kind, per version). It does NOT replay
+the agent loop against fresh inputs; recorded-replay is a later
+increment (see the metrics module docstring).
+
+Benchmark schema (``cases_json``)
+--------------------------------
+A JSON list of scored case dicts. Each case has:
+
+    {
+      "outcome_kind": str,
+      "predicted_verdict": "accept" | "reject",
+      "verified_verdict":  "accept" | "reject",
+      "confidence": float in [0, 1],
+      "version": str | null       # optional; see below
+    }
+
+The optional ``version`` field attributes a case to the predictor that
+produced it. The runner partitions cases into two bundles:
+
+- candidate bundle: cases whose ``version`` equals ``candidate_version``
+  OR whose ``version`` is None (shared / common ground truth).
+- baseline bundle:  cases whose ``version`` equals ``baseline_version``
+  OR whose ``version`` is None.
+
+Both bundles include the unversioned cases so a benchmark can carry a
+shared floor of ground truth alongside per-version predictions. A run
+against a candidate with no versioned cases (and no unversioned ones)
+raises: an empty bundle is a misconfiguration, not a passing eval.
+
+Runner flow
+-----------
+1. Load the benchmark row -- raise ``BenchmarkNotFoundError`` if absent.
+2. Resolve the current 'production' alias for ``key`` via
+   ``PromptVersionStore`` -- baseline is None on a first-ever eval.
+3. Build an ``EvalReport`` for the candidate bundle. Build the baseline

Subject: [PATCH 252/281] feat(resilience): infra-death classifier +
 SSE-write-failure counter (RFC-07)

First increment of the self-healing resilience layer, narrowed to the
gaps that are not already covered by the shipped recovery services.

- infra_death.py: pure InfraDeathClassifier.classify(branch_turn_count,
  recent_turn_errors, llm_unhealthy_at_close) -> 'infra_death'|'terminal'.
  Returns 'infra_death' when the LLM was unhealthy at close or a trailing
  turn error is in RETRYABLE_INFRA_CLASSES; 'terminal' on a clean tail or
  zero turns (deferred to the outer zero-turn guard).
- investigation_finalizers: synthesize_no_finding_outcomes now classifies
  a multi-turn investigation before writing a no-finding outcome. On an
  infra-death verdict it marks the investigation FAILED (retryable) with
  closed_reason 'auto_closed_infra' and skips the hollow no-finding
  synthesis, instead of masking an outage as a clean negative. Zero-turn
  and outage-skip paths are preserved.
- SSE progress-write swallows in events/emitter.py and workflows/log.py
  now log at WARNING and increment aila_sse_write_failures_total (labeled
  emitter|workflow_log) so a frozen progress bar is observable. Still
  fail-safe: a progress-write failure never kills the turn.

Tests: 14 (13 pure classifier + 1 finalizer DB integration proving the
auto_closed_infra FAILED path). Regression: event_emitter (9) and the
malware finalizer LLM-unhealthy guard (1) stay green. No schema change.

+"""Infra-death classifier for multi-turn investigation finalization.
+
+Problem this closes (RFC-07, first increment):
+
+The synthesize_no_finding_outcomes finalizer already skips synthesis
+when the LLM is currently unhealthy AND already downgrades a zero-turn
+investigation to FAILED (retryable) instead of writing a hollow
+no-finding outcome. Neither guard catches the following live shape:
+
+  * The investigation ran real turns (turn_count > 0).
+  * Its trailing N turns died to an infra failure -- LLM timeout,
+    rate-limit exhaustion, provider connection reset, or a stale-branch
+    abandonment triggered by a bounded LLM outage window.
+  * The LLM endpoint recovered BEFORE the finalizer tick fires.
+  * The outer is_llm_recently_unhealthy() gate therefore reads healthy,
+    the branches look "terminal" via abandoned closed_reason, and the
+    finalizer writes a clean no-finding outcome that reads to the
+    operator as "we audited and found nothing" instead of "the tail
+    of the run died to infrastructure".
+
+The classifier is intentionally PURE so the caller stays responsible
+for gathering signals (branch turn totals, trailing error classes,
+current llm-health snapshot). This keeps the finalizer control flow
+transparent and the classifier trivially testable without a DB.
+
+Return contract:
+    "infra_death" -- caller must NOT synthesize a clean no-finding
+                     outcome; instead mark the investigation FAILED
+                     (retryable) with a distinct closed_reason so the
+                     operator can reopen / re-enqueue.

Subject: [PATCH 253/281] feat(knowledge): content-aware chunker + pattern
 relevance floor (RFC-12)

First increment of the knowledge retrieval overhaul, schema-free.

- ingestor.py: KnowledgeIngestor, a pure content-aware chunker.
  chunk_code splits on function/class leading tokens across common
  languages; chunk_document splits on markdown headings; both hard-split
  any unit exceeding max_chars so no emitted chunk overflows. Empty input
  yields []. chunk(text, kind, max_chars) dispatches and validates.
- KnowledgeService.store() gains an opt-in keyword path (chunked, kind,
  chunk_max_chars). The default path is byte-identical -- existing callers
  are untouched. chunked=True writes one boundary-aligned row per chunk
  with a per-chunk dedup_key suffix and chunk_index/chunk_count/chunk_kind
  in the existing entry_metadata JSON, reusing the dedup upsert so a
  re-ingest updates rows in place.
- PatternStoreBase.applicable() enforces a non-zero relevance floor:
  min_score is passed to retrieve() AND re-checked in-loop so a caller
  KnowledgeService that ignores min_score still gets the floor. The floor
  resolves via ConfigRegistry (env override supported), falling back to
  PATTERN_RELEVANCE_FLOOR_DEFAULT=0.3. Low-similarity pattern hits stop
  entering researcher prompts.

Tests: 28 (21 chunker boundary/dispatch/edge + store round-trip, 7 floor
resolution + drop). Existing knowledge upsert/hybrid tests stay green.
No schema change; Alembic head remains 089.

+"""KnowledgeIngestor -- content-aware chunker for knowledge-store ingestion (RFC-12).
+
+Splits long inputs on structural boundaries (function/class heads for source,
+markdown heading rows for prose) so each chunk lands as its own row in the
+knowledge base. Boundary-aligned chunks embed cleanly, keep retrieval
+precise, and stop a 20 KB blob from producing a single averaged vector that
+dilutes every query it participates in.
+
+The chunker is regex-based (no AST). One code path serves Python, Go, Rust,
+Java, Kotlin, C/C++, JavaScript, TypeScript, and similar languages by
+matching the shared leading tokens (``def``, ``async def``, ``class``,
+``func``, ``fn``, ``function``, and the Java-family access modifiers). Every
+method is pure text-in / list-of-strings-out -- no I/O, no DB, no model
+calls -- so the chunker is trivially unit-testable and safe to reuse across
+threads and workers.
+
+``KnowledgeService.store()`` opts into chunked ingestion via ``chunked=True``
+plus a ``kind`` hint; the default (non-chunked) store path is unchanged for
+existing callers.

Subject: [PATCH 254/281] feat(lifecycle): agent lifecycle control plane --
 evaluate/promote/rollback (RFC-10)

First increment of the agent development lifecycle, built on the shipped
RFC-08 eval runner and RFC-09 prompt version store.

- lifecycle/models.py: LifecycleStage enum (built, evaluated, shadow,
  canary, production, rolled_back) + LifecycleTransitionRecord journal
  table (lifecycle_transitions, migration 091).
- lifecycle/controller.py: AgentLifecycleController.
  evaluate delegates scoring to EvalRunner.run(auto_promote=False) and
  journals a built/prior -> evaluated transition carrying the verdict +
  report. promote is stage-guarded -- it requires a prior passing
  'evaluated' transition for the (key, version) before flipping the
  production alias, raising StageTransitionError otherwise (alias
  untouched on refusal). rollback flips production back to the prior
  version (from the journal or an explicit target) and journals
  production -> rolled_back. No FK to eval_runs; the eval_run_id lives in
  metrics_snapshot_json so an eval-row purge cannot corrupt the journal.

Shadow and canary stages are deferred (they need record-replay + cohort
routing that do not exist yet). Tests: 6 (evaluate journals verdict;
promote flips alias after a pass; promote without/with-failing evidence
raises and leaves the alias; rollback reverts + journals; row columns
populated). No app.py surface yet -- a later increment adds the router.

+"""091 -- agent lifecycle transition journal (RFC-10 step 1).
+
+Creates ``lifecycle_transitions`` -- one row per agent-behavior
+lifecycle stage transition (built -> evaluated -> production ->
+rolled_back). Each row carries the prompt key + version, the from/to
+stages, the actor + reason, and a ``metrics_snapshot_json`` blob holding
+the eval verdict / report bundle (evaluate rows) or the restored target
+version (rollback rows).
+
+Columns match the SQLModel definition in platform/lifecycle/models.py so
+``create_all`` (tests, fresh installs) matches the migrated schema. Index
+names are prefixed ``ix_lifecycle_transitions_`` because Postgres index
+names are database-scoped, not table-scoped. There is no FK to
+``eval_runs`` -- the ``eval_run_id`` lives inside
+``metrics_snapshot_json`` as an opaque string so an eval-row purge cannot
+cascade-corrupt the lifecycle journal. Guarded with ``IF NOT EXISTS`` so
+a re-run or a fresh database that already carries the table is a no-op.

+"""RFC-10 agent lifecycle: stage vocabulary + append-only transition journal.
+
+The lifecycle control plane owns two things: the stage machine (this file's
+``LifecycleStage`` StrEnum) and the append-only journal of stage moves
+(``LifecycleTransitionRecord``). Every observed change to the operator
+alias for a prompt key -- eval-verified promotion, rollback to a prior
+production version, or a re-eval on a candidate that stayed in
+``evaluated`` -- writes exactly one row here. The controller in
+``platform/lifecycle/controller.py`` is the only writer.
+
+Only ``built``, ``evaluated``, ``production``, and ``rolled_back`` are
+wired in the first RFC-10 increment. ``shadow`` and ``canary`` are
+reserved for a later increment that runs a live traffic-mirroring
+comparison; declaring them now keeps the stage vocabulary stable so
+downstream operator UIs need not migrate the enum on that increment.
+
+Constraint and index names carry the ``lifecycle_transitions_`` prefix
+so they stay unique across the platform schema (Postgres constraint
+names are database-scoped, not table-scoped -- the same lesson eval
+and prompt tables learned).

+2. Promote after a passing evaluate -> production alias flipped to the

+3. Promote WITHOUT a prior passing evaluate (either no evaluate at all,

+4. Rollback -> production alias returns to the prior production version
+   + a 'production' -> 'rolled_back' transition journaled on the

+5. LifecycleTransitionRecord row has all columns populated (id, key,

Subject: [PATCH 255/281] feat(mcp): DB-backed MCP server instance catalog
 (RFC-11)

First increment of hot-pluggable MCP: an operator-editable catalog of
server instances, without touching the live dispatch path.

- instance_catalog.py: McpServerInstance table (mcp_server_instances,
  migration 092) + McpInstanceCatalog async CRUD service. capability_tags
  stored as JSON text; natural key (module_scope, name) so one server
  name can appear under multiple modules.
- routers/mcp_instances.py: god-tier-admin CRUD at
  /platform/mcp/instances (GET/POST/PATCH/DELETE), 409 on duplicate
  scope+name, 400 on bad transport / empty patch, 404 on unknown id.
- registry.py: McpRegistryServiceBase URL resolution gains a catalog
  tier -- env > ConfigRegistry > enabled catalog row > code default. A
  disabled row is a no-override; a catalog DB error logs at WARNING and
  falls back to the default. When no row exists for (module_scope, name),
  resolution is byte-identical to the prior behaviour.

The catalog starts empty (no seed), so live dispatch is unchanged until
an operator adds rows; bridges, adapters, the tool executor, and
_applicable_servers_for_kind are byte-untouched. Tests: 25 (catalog
model round-trip + service CRUD, JSON tag codec, scope filter; API
create/list/patch/delete/duplicate/non-admin).

+"""092 -- MCP server instance catalog (RFC-11 step 1).
+
+Creates ``mcp_server_instances`` -- an operator-editable catalog of MCP
+server registrations. ``McpRegistryServiceBase`` MAY consult it as a
+default that beats the code-embedded ``default_url`` but stays below the
+``env`` and ``config`` overrides. When no row exists for a given
+``(module_scope, name)`` the URL resolution is byte-identical to the
+pre-catalog behaviour, so this table does not touch live dispatch.
+
+Columns match the SQLModel definition in platform/mcp/instance_catalog.py
+so ``create_all`` (tests, fresh installs) matches the migrated schema.
+The unique constraint and index names are prefixed for the
+database-scoped Postgres namespace. Guarded with ``IF NOT EXISTS``.
+
+No seed rows: the catalog starts empty and resolution falls back to the
+per-module static ``MCP_SERVERS`` tuples, so live investigations are
+unaffected. Operators add instances via ``POST /platform/mcp/instances``.

+"""RFC-11 step 1 -- DB-backed MCP server instance catalog.
+
+An operator-editable catalog of MCP server instances (audit-mcp,
+ida-headless, android-mcp, and future servers) persisted in
+``mcp_server_instances`` and administered through the
+``/platform/mcp/instances`` REST surface. Live dispatch stays untouched:
+:class:`aila.platform.mcp.registry.McpRegistryServiceBase` MAY consult
+the catalog as an operator-editable default that beats the code-embedded
+``default_url`` but stays below ``env`` and ``config`` overrides. When
+no catalog row exists for a given ``(module_scope, name)``, resolution
+is byte-identical to the pre-catalog behaviour.
+
+Each row carries:
+
+* ``id`` -- stable primary key (uuid by default; the migration seeds
+  descriptive ids so operators can address rows without a lookup).
+* ``name`` -- the stable server token that matches ``spec['id']`` in
+  the module's static :class:`MCP_SERVERS` tuple (``"audit_mcp"``,
+  ``"ida_headless"`` ...). The registry looks up catalog rows by
+  ``(module_scope, name)``, so this field is the join key.
+* ``transport`` -- ``"http"`` or ``"stdio"``. The current bridges are
+  HTTP-only; ``"stdio"`` reserves the row for the future stdio subprocess
+  transport without a schema migration.
+* ``endpoint`` -- HTTP base URL for ``http`` rows, command line for
+  ``stdio`` rows. Bridges keep resolving via
+  :meth:`McpRegistryServiceBase._resolved_url`; this field replaces the
+  static ``default_url`` when catalog resolution kicks in.
+* ``capability_tags`` -- JSON-encoded ``list[str]`` describing the
+  capability groups the instance advertises (``["source_audit",
+  "graph"]``). Serialisation lives on the service; the column stores
+  raw JSON text.
+* ``enabled`` -- disables the row without deleting it (kept in the
+  catalog for audit history and quick re-enable).
+* ``module_scope`` -- module id namespace (``"vr"``, ``"malware"``,
+  ``None`` for platform-wide). Combined with ``name`` for the natural
+  unique key so ``audit_mcp`` can appear under multiple modules.
+* ``created_at`` / ``updated_at`` -- lifecycle timestamps written by
+  the service, not by SQLAlchemy defaults, so ``updated_at`` remains
+  ``None`` until the first mutation and moves atomically on ``set_``
+  / ``update_`` calls.

Subject: [PATCH 256/281] refactor(agents): consolidate run_turn into platform
 AgentTurnRunnerBase (RFC-03 Phase 7)

The per-branch reasoning turn (vr 502L, malware 549L, 0.86 normalized
similarity) is consolidated into AgentTurnRunnerBase.run_turn on the
platform, the sibling of the already-merged ToolExecutorHelpersBase.
Both researchers now inherit one turn loop. Per-module differences are:

- config class attrs: _LOG_LABEL, _error_cls, _result_cls,
  _message_model, _branch_model, _OUTCOME_STATE_APPROVED,
  _EMPTY_TOOLRUN_DIRECTIVE.
- staticmethod bindings for the per-module module-level helpers
  (_fetch_tool_specs, _load_prompt, _decision_to_message_payload,
  _terminal_outcome_kind, _outcome_payload, _upsert_canonical_outcome,
  _resolve_task_type, _evaluate_quorum, _upsert_review), bound at module
  import time since they are defined below the class.
- override hooks: _extra_user_prompt_kwargs (VR adds cve_intel),
  _maybe_reject_fanout_submit (VR variant-hunt gate / malware fan-out
  gate), _review_vote_and_comment (malware downgrades an empty-rationale
  reject to abstain), _dispatch_approved_outcome (per-module dispatch
  task), _handle_edit_outcome (malware edit_outcome action).

The shared skeleton (load, prompt build, idempotency-cached engine call,
absorb, message + branch persist, terminal outcome upsert, review
handling, empty-tool_run coerce) now lives once; both modules keep only
their domain helpers and the hook bodies. Removes ~500 duplicated lines.

Verified: compileall, ruff, honesty_audit (0 findings), and a full
faithfulness audit confirming every vr/malware run_turn divergence maps
to a hook, config attr, or staticmethod binding while the shared
non-seam skeleton stays line-identical. Structural smoke asserts both
researchers inherit the base run_turn with every binding/attr/hook
resolving and the correct per-module overrides. 125 agent + loop +
researcher tests stay green. run_turn drives the live DB + engine + MCP
and has no unit-test surface; its end-to-end behavior is gated on the
operator live-investigation smoke at merge.

-        # per `variant_hunt_orders` entry on the payload. After the

-        # continue (fba2a08) landed, agents started investigating
-        # candidates inline for the whole 60+ turn budget and submitting
-        # carrying `variant_hunt_orders=[]` AND no exhaustion declaration --
-        # collapsing the variant-hunt fan-out from ~120 children/day to
-        # ~2/day overnight (5-21 → 5-22). The submit was technically
-        # valid but it produced ZERO downstream investigations on
-        # exactly the investigation kind whose entire purpose is to
-        # fan out variant probes.
-        #
-        # The gate intercepts that submit and forces the agent to either:
-        #   (a) populate variant_hunt_orders with the candidates it
-        #       investigated inline (child investigations confirm-and-
-        #       extend, not duplicate work), or
-        #   (b) explicitly declare exhaustion via a recognised phrase

+"""Shared agent turn runner (RFC-03 Phase 7).
+
+``AgentTurnRunnerBase.run_turn`` is the single per-branch reasoning turn:
+load state, build the prompt, call the engine (idempotency-cached),
+absorb the decision, persist the message + branch state, upsert the
+canonical outcome on a terminal submit, and handle the outcome-review /
+edit-outcome side paths. It was lifted verbatim from the byte-shared
+skeleton of the vr and malware researchers; the per-module differences
+are expressed as:
+
+* class attributes -- ``_LOG_LABEL``, ``_error_cls``, ``_result_cls``,
+  ``_message_model``, ``_branch_model``, ``_OUTCOME_STATE_APPROVED``.
+* staticmethod bindings for the per-module module-level helpers
+  (``_fetch_tool_specs``, ``_load_prompt``, ``_decision_to_message_payload``,
+  ``_terminal_outcome_kind``, ``_outcome_payload``, ``_upsert_canonical_outcome``,
+  ``_resolve_task_type``, ``_evaluate_quorum``, ``_upsert_review``).
+* override hooks -- ``_extra_user_prompt_kwargs``,
+  ``_maybe_reject_fanout_submit``, ``_review_vote_and_comment``,
+  ``_dispatch_approved_outcome``, ``_handle_edit_outcome``.
+
+Subclasses also provide the shared instance methods the runner calls on
+``self`` (``_load``, ``_build_user_prompt``,
+``_consume_pending_operator_messages``, ``_load_prior_outcomes``,
+``_load_sibling_context``, the three pre-submit gates) and the
+``_engine`` / ``investigation_id`` / ``branch_id`` / ``_applicable_patterns``
+instance state.

+        # per `variant_hunt_orders` entry on the payload. After the
+        # turn-budget bump (c912d5b: 25→60→70) + branch-aware auto-
+        # continue (fba2a08) landed, agents started investigating
+        # candidates inline for the whole 60+ turn budget and submitting
+        # carrying `variant_hunt_orders=[]` AND no exhaustion declaration --
+        # collapsing the variant-hunt fan-out from ~120 children/day to
+        # ~2/day overnight (5-21 → 5-22). The submit was technically
+        # valid but it produced ZERO downstream investigations on
+        # exactly the investigation kind whose entire purpose is to
+        # fan out variant probes.
+        #
+        # The gate intercepts that submit and forces the agent to either:
+        #   (a) populate variant_hunt_orders with the candidates it
+        #       investigated inline (child investigations confirm-and-
+        #       extend, not duplicate work), or
+        #   (b) explicitly declare exhaustion via a recognised phrase
+        #       (matches outcome_dispatcher._VARIANT_EXHAUSTION_PATTERN
+        #       -- NO FURTHER VARIANTS, VARIANT DEAD, etc.)

Subject: [PATCH 257/281] refactor(agents): route agent submit-gate caps
 through ConfigRegistry (RFC-03)

Closes the RFC-03 config-drift acceptance item: no os.environ / os.getenv
under modules/*/agents/**. Six import-time env-read caps are replaced by
operator-tunable ConfigRegistry keys resolved at the use site (env -> DB
-> schema default), so a PUT /config override lands on the next turn
without a worker restart.

- Register keys: VR (variant_hunt_reject_cap, unresolved_hyp_reject_cap,
  tool_executor_hard_block_repeat) and malware (unresolved_hyp_reject_cap,
  sub_investigation_reject_cap, max_sub_inv_per_parent) in the module
  ConfigSchemas, all with their prior defaults (3, except max_sub_inv=5).
- AgentTurnRunnerBase gains a no-op _load_turn_config hook called once at
  the top of run_turn; each researcher overrides it to stash its gate caps
  as instance attributes via get_int, so the sync submit-gate methods read
  a resolved value without an await. Drops the module-level cap constants.
- ToolExecutorHelpersBase.execute reads the hard-block threshold via a new
  _hard_block_repeat_limit hook (base default None; VR resolves from
  config); malware keeps the None default (no hard block).
- The malware outcome dispatcher reads max_sub_inv_per_parent via get_int
  inside _dispatch_analysis_report.

Behavior note: the operator env-var names change from the raw VR_* /
MALWARE_* form to the standard AILA_VR_<KEY> / AILA_MALWARE_<KEY> form
(the same migration the cap-exceeded reaper caps already made). Defaults
are unchanged, so an operator who never set the old env vars sees no
difference. Verified: honesty_audit 0, the acceptance grep returns
nothing, schema keys match the get_int calls, 130 agent + researcher +
dispatcher + loop tests green.

Subject: [PATCH 258/281] fix(api): derive search result module_id from the
 resolved module (RFC-05)

The shared search router hardcoded module_id="vulnerability" on finding
results even though the module was resolved by capability via
first_with("latest_findings"). A second module exposing latest_findings
would have had its results mislabeled as vulnerability. The value now
reads module.module_id from the resolved module. The platform_names_module
honesty rule checks .require() calls, so this string literal had evaded
the audit.

Subject: [PATCH 259/281] feat(knowledge): stamp per-vector provenance + wire
 relevance floor to config (RFC-12)

Closes the provenance half of RFC-12 criterion 1 and the pattern
relevance-floor config-schema wiring.

- KnowledgeEntryRecord gains model_id, content_hash, source_type (indexed)
  and updated_at columns (migration 093, all nullable so the add runs on a
  populated table with no backfill). KnowledgeService.store now stamps
  every write -- model_id from the resolved embedding provider, content_hash
  as the sha256 of the stored text (per chunk on the chunked path),
  source_type from the ingest kind, updated_at on insert and update. This
  makes each stored vector attributable to the model that produced it and
  detectable on content change.
- PlatformConfigSchema gains knowledge_pattern_relevance_floor (default
  0.3). PatternStoreBase._resolve_relevance_floor now resolves it from the
  platform config schema via ConfigRegistry, keeping the module constant as
  the last-resort fallback. The stale "a future schema field" comment is
  removed now that the field exists.

Contextual enrichment, adaptive routing, CAG/graph, sanitize/classify, and
record-replay retrieval eval remain later RFC-12 increments.

Subject: [PATCH 260/281] refactor(platform): extract branch/message/outcome
 summary builders (RFC-02)

Closes RFC-02 criterion 2. build_branch_summary, build_message_summary,
and build_outcome_summary now live in platform/services/investigation_
summaries.py alongside build_investigation_summary, and both vr and malware
api_routers call them instead of carrying private copies that could drift.

Divergences preserved, not dropped: the malware branch summary keeps its
acked_at field (the platform builder forwards it only when the summary
contract declares it), and the outcome builder takes a review_counts dict
so malware's five vote-count fields survive while VR keeps its zero-count
default. The NULL-state dispatch fallback is now shared by both modules.

Subject: [PATCH 261/281] feat(api): admin HTTP surface for the agent lifecycle
 controller (RFC-10)

Closes the "without a code release" operator surface of RFC-10 criterion 2.
AgentLifecycleController.evaluate/promote/rollback/list_transitions are
exposed at POST /admin/lifecycle/{evaluate,promote,rollback} and GET
/admin/lifecycle/transitions, god-tier-admin gated, rate-limited, and
DataEnvelope-wrapped, mirroring the admin_eval router. The actor is derived
from the auth context, not the request body, so it cannot be forged.
StageTransitionError surfaces as HTTP 409 (a promote with no passing
evaluate journal row is rejected), BenchmarkNotFoundError as 404. No
schema change: lifecycle_transitions already shipped in migration 091.

Shadow/canary stages and the review-quorum promotion gate remain tracked
follow-ups.

+"""Admin agent-lifecycle router (RFC-10 step 4).
+
+Operator surface for the ``AgentLifecycleController``: evaluate a
+candidate prompt version against a benchmark, promote a version that
+has cleared its evaluation gate, rollback the production alias to a
+prior production version, or read the append-only transition journal.
+Every endpoint writes (or reads) a ``LifecycleTransitionRecord`` row --
+the stage moves that this router exposes are the same ones an operator
+would otherwise trigger by hand through a code release.
+
+All endpoints require god-tier admin (team_id=None): the production
+alias for a prompt key is platform-wide and gates every team's
+investigations, exactly like the underlying prompt-version store
+(RFC-09) and the eval-harness (RFC-08). Every request is rate-limited
+to match the admin-eval / admin-prompts routers.
+
+Endpoints:
+    POST /admin/lifecycle/evaluate       score a candidate + journal a transition
+    POST /admin/lifecycle/promote        flip production alias if the eval passed
+    POST /admin/lifecycle/rollback       flip production alias back to a prior version

Subject: [PATCH 262/281] feat(lifecycle): enforce review-quorum on agent
 promotion (RFC-08/RFC-10)

Closes the "eval gate AND quorum approval" half of RFC-10 criterion 1 and
RFC-08 criterion 2. Promotion was gated on eval-pass alone; a distinct-
approver quorum now stands beside it.

- LifecycleStage gains APPROVED (between EVALUATED and PRODUCTION; no
  migration -- transition stages are TEXT).
- AgentLifecycleController.approve(key, version, actor, reason) requires a
  passing evaluated journal row, then journals evaluated -> approved.
- promote() now also counts DISTINCT approver actors on approved
  transitions for (key, version) and refuses with StageTransitionError
  naming approvals-present vs required when below the quorum. The promote
  journal snapshot records approver_count + quorum_threshold.
- PlatformConfigSchema.agent_promotion_quorum (default 1) is the required
  distinct-approver count, tunable via PUT /config with no restart.
- POST /admin/lifecycle/approve exposes it; actor derives from the auth
  context. The eval-runner auto_promote fast path stays eval-only and
  admin-opt-in by construction; the quorum-gated path is the controller.

Subject: [PATCH 263/281] refactor(agents): extract PersonaRouter,
 PatternExtractor, OutcomeDispatcher to platform (RFC-03 Phase 5/6)

Removes three duplicated agent primitives that the audit found still lived
as full copies in both vr and malware -- the exact duplication RFC-03
exists to eliminate. Each is now a platform base with per-module hooks and
class attributes; the module classes keep their names as thin subclasses,
so every existing import site and aggregator re-export stays untouched.

- PersonaRouter: the shared persona -> role table and coercion move to the
  platform; each module supplies its default_task_type plus its role- or
  persona-keyed task_type table as class attrs.
- PatternExtractor: the ~550-line body collapses to an 85-line subclass per
  module; PatternExtractorBase owns the load -> gate -> transcript ->
  prompt -> idempotent_llm_call -> parse -> store flow, with record models,
  enums, prompt path, and task_type as class attrs.
- OutcomeDispatcherBase owns the claim -> guard -> per-kind route ->
  persist skeleton (the TOCTOU stays closed via the platform
  claim_outcome_for_dispatch service); each module supplies its per-kind
  handlers, state guard, and terminal persistence (VR keeps its sibling-
  halt + investigation-complete + ARQ-purge cascade). Behavior note: VR's
  dispatch of a missing outcome now returns a SKIPPED outcome_not_found
  result instead of raising ValueError, converging on malware's shape.
  Verified inert: two VR callers wrap the call and two dispatch an outcome
  read + committed moments earlier, so the not-found path cannot fire.

Characterization tests pin both module configurations for each primitive;
191 agent + lifecycle tests pass.

-"""Per-role model routing (v0.4 GA-52).
+"""VR persona -> LLM task_type router (RFC-03 Phase 5 thin binding).
 
-Each strategy branch can carry a PersonaVoice. v0.4 introduces a
-role-based mapping from persona → task_type, which the platform's
-LLM client uses to resolve routing (model, temperature, max_tokens).
+The persona -> role table, the resolution logic, and the base class
+live once in :mod:`aila.platform.agents.persona_router`. This module
+binds the vr-specific task_type table: personas that share a role
+share a task_type (researcher / implementer / critic).
 
-v1 ships a deterministic static map. v1.1 will read the mapping from
-``vr.branch_model_routing`` ConfigRegistry namespace so operators can
-override per-team without code changes.
+Default role -> task_type bindings:
 
-Default role → task_type bindings:
-
-  researcher (halvar, noor)      → vulnerability_research.researcher
-  implementer (renzo, wei)       → vulnerability_research.implementer
-  critic (maddie, yuki)          → vulnerability_research.critic
+  researcher (halvar, noor)      -> vulnerability_research.researcher
+  implementer (renzo, wei)       -> vulnerability_research.implementer
+  critic (maddie, yuki)          -> vulnerability_research.critic
 
 The task_type values resolve through the platform's existing LLM
 routing config. Operators tune them via the standard config UI:
 which model (Claude vs GPT-5), what temperature, what context window.
+When no persona is assigned (legacy single-persona flow), routing
+falls back to ``vulnerability_research.audit``.

+"""Shared OutcomeDispatcher skeleton (RFC-03 Phase 6).
+
+Both the vr and malware modules ship a dispatcher that:
+
+1. Atomically claims an accepted outcome for dispatch via the platform
+   service ``claim_outcome_for_dispatch`` (closes the TOCTOU that would
+   otherwise let two workers double-dispatch the same outcome).
+2. Routes the winning claim to a per-kind handler that materialises the
+   downstream artifact (child investigation, finding row, knowledge
+   entry, YARA rule row, ...).
+3. Persists the terminal ``dispatch_status`` (+ optional
+   ``dispatch_target``) on the outcome row.
+
+Everything OUTSIDE the per-kind body is the same skeleton. This module
+owns that skeleton; each module subclasses with its own per-kind body.
+
+Subclass contract (see :class:`OutcomeDispatcherBase`):
+
+* Class attributes
+    ``_outcome_model``           the module's SQLModel outcome record class.
+    ``_outcome_kind_cls``        the module's ``OutcomeKind`` StrEnum type.
+    ``_default_error_kind``      the kind stamped into the SKIPPED result
+                                 returned for ``outcome_not_found`` and for

+                                 does not parse as ``_outcome_kind_cls``.
+    ``_catch_handler_errors``    ``True`` folds handler exceptions into a
+                                 FAILED result; ``False`` re-raises so the
+                                 caller records the failure and retries.
+    ``_log_label``               log-line prefix used for RESULT / FAILED
+                                 lines.
+
+* Overridable hooks
+    ``_dispatch_state_guard(row)``    optional pre-claim guard passed to
+                                      ``claim_outcome_for_dispatch``; return
+                                      a skip reason to refuse the claim, or
+                                      ``None`` to allow it. Default: allow.
+    ``_load_outcome_row(outcome_id)`` optional post-claim reload of the
+                                      outcome row; returned value is passed
+                                      to ``_handle_kind`` as ``outcome_row``.
+                                      Default: ``None`` (skip the reload
+                                      and route from the claim snapshot).
+    ``_handle_kind(...)``             REQUIRED. Route to the per-kind
+                                      handler. Receives the claim snapshot
+                                      (kind, payload, investigation_id) plus
+                                      the reloaded ``outcome_row``.
+    ``_persist_dispatch_status(...)`` write the terminal status onto the
+                                      outcome row. Default: minimal write
+                                      of ``dispatch_status`` +
+                                      ``dispatch_target``. Modules override
+                                      to add cross-row side effects (halt

+
+The dispatch skeleton also folds two invariants shared by both modules:
+
+* A missing outcome (``claim.found=False``) returns SKIPPED with reason
+  ``"outcome_not_found"`` rather than raising, so the ARQ worker that
+  runs the dispatch does not retry a permanently-missing row. Both
+  callsites (vr and malware) already wrap dispatch in a broad
+  try/except that catches this shape, so returning the SKIPPED result
+  is a defensive normalisation.
+* Not-won claims where the guard returned ``unknown_outcome_kind:<x>``
+  land as FAILED (data-shape bug the operator must see) while every
+  other not-won reason lands as SKIPPED (the row is fine, just not
+  dispatchable by this caller).

+"""Shared pattern extractor (RFC-03 Phase 5).
+
+``PatternExtractorBase.extract`` is the single per-outcome extraction
+pass: load the outcome + investigation + target, render the transcript,
+prompt the LLM through the idempotency cache, validate the response,
+and persist each extracted pattern via the module's ``PatternStore``.
+It was lifted verbatim from the byte-shared skeleton of the vr and
+malware extractors; the per-module differences are expressed as class
+attributes that every subclass sets:
+
+* ``_LOG_LABEL`` -- log-line prefix (``"pattern_extractor"`` by default).
+* ``_task_type`` -- the ``idempotent_llm_call`` task-type key (per module
+  because cost / rate-limit routing is module-scoped).
+* ``_extraction_outcome_kinds`` -- the frozenset of ``OutcomeKind`` values
+  where extraction is meaningful. Every other kind returns ``skipped``.
+* ``_outcome_kind_enum`` -- the module's ``OutcomeKind`` StrEnum, used to
+  coerce ``outcome.outcome_kind`` (a raw string on the row) back to the
+  enum for the ``should_extract`` gate.
+* ``_pattern_kind_enum`` / ``_pattern_confidence_enum`` /
+  ``_pattern_scope_enum`` -- the module's pattern enums. The schema
+  builder emits each enum's ``.value`` list into the JSON schema so the
+  LLM only picks from valid strings for that module.
+* ``_pattern_create_cls`` -- the module's ``PatternCreate`` Pydantic
+  model (``VRPatternCreate`` / ``MalwarePatternCreate``).
+* ``_outcome_model`` / ``_investigation_model`` / ``_target_model`` /
+  ``_message_model`` / ``_branch_model`` -- the module's SQLModel record
+  classes, used in the read-only SELECT queries + the skip-event write.
+* ``_prompt_path`` -- absolute path to the module's
+  ``pattern_extraction.md`` template.
+
+Public API kept identical to the pre-extraction modules:
+``PatternExtractor``, ``PatternExtractionResult``, ``PatternExtractorError``.
+Each module's thin subclass keeps the ``PatternExtractor`` class name so
+existing aggregator re-exports and import sites work untouched.

+        ~5000 messages were materialising 20-100 MB into worker memory
+        before truncation happened in Python. The LIMIT picks the
+        newest messages (DESC) and reverses to chronological order
+        so the head/tail rendering still matches the original
+        timeline.
+
+        fix §194 -- keep first 5000 chars + last 25000 chars (was
+        last 30000). The seed prompt + initial hypothesis statement
+        live in the first ~2000 chars; the previous "keep tail only"
+        scheme dropped exactly the lens the extractor needs.
+
+        fix §195 -- append the canonical outcome's ``panel_summary``
+        (when present) at the END of the transcript so the extractor
+        always sees the synthesised verdict regardless of where the
+        message-row truncation landed.

+"""Characterization tests for the platform PatternExtractor (RFC-03 Phase 5).
+
+Exercises the extraction logic for BOTH module configs (vr + malware) so
+the pre-extraction behavior is preserved. Every LLM call is mocked; the
+DB round-trip is patched via ``_load`` / ``_load_transcript`` so no
+migrations or infra are required.
+
+Coverage:
+  * ``should_extract`` accepts each module's extractable OutcomeKind
+    set (and rejects the non-extractable ones).
+  * ``_entry_to_create`` builds the module-specific PatternCreate row
+    with the correct enum types, workspace_id / investigation_id
+    plumbing, ``PatternScope.LOCAL`` scope, summary truncation, and the
+    defensive normalisation of malformed applicability / evidence_refs.
+  * ``_extraction_schema`` reflects the module's PatternKind +
+    PatternConfidence enums (LLM never sees a value the module has no
+    definition for).
+  * The happy-path ``extract`` persists each LLM-emitted pattern via the
+    store and returns the persisted ids in the result.
+  * The empty-list, non-JSON, wrong-shape, non-extractable, and
+    kill-switch skip paths return the expected ``PatternExtractionResult``
+    without crashing.
+
+The test parametrises on a small ``_Config`` struct so both modules run
+through the identical assertion set -- any drift between the vr and
+malware subclass classes would immediately break one variant.

Subject: [PATCH 264/281] refactor(agents): extract ClaimVerifierAgent +
 SynthesisAgent to platform (RFC-03 Phase 5)

Removes the last two duplicated agent primitives the audit found living as
full copies in both vr and malware, completing RFC-03 Phase 5/6.

- ClaimVerifierAgentBase owns the two-stage extractor -> verdict pipeline,
  the probe allowlist + signature fetch + payload render, the parsers and
  verdict renderer, the persist unit-of-work, and the auto-promote /
  revert skeleton. vr collapses 1140 -> 149 lines, malware 1212 -> 238.
  Per-module knobs (task_type keys, negative-phrase tables, record models,
  outcome-dispatcher class, promote source/target kinds, auto-promote
  floor, claim-text extraction) are class attrs + hooks. Both idempotent
  LLM call sites and the OutcomeDispatcher promotion call are preserved.
- SynthesisRunnerBase owns the load -> panel -> prompt -> chat_structured
  -> validate -> persist flow with the two-UoW alive-status re-check and
  the terminal status flip. vr and malware supply their own SynthesisResponse
  schema, system prompt, and panel renderer; malware keeps its richer
  schema + SynthesisOptions via hook overrides (force-resynthesize,
  status-flip suppression, payload extras).

Prompts stay inline as class attrs for now; routing them through the
version store is the separate RFC-09 slice. Characterization tests pin both
module configurations at the mocked idempotent-LLM seam; 131 new + 40
existing synthesis/claim tests pass.

-"""ClaimVerifierAgent -- adversarial verification of canonical-outcome claims.
-
-Runs AFTER the synthesis agent has consolidated the deliberation panel
-into a single narrative. The verifier's job is the opposite of the
-deliberation panel: instead of producing a finding, it tries to REFUTE
-the finding the panel produced.
-
-The flow:
-
-    1. EXTRACTOR LLM call -- parses ``canonical_outcome.payload.answer``
-       (and ``panel_summary.narrative`` if present) into a structured list
-       of falsifiable preconditions. Each precondition carries a single
-       ``audit_mcp.<tool>(...)`` probe call whose result will either
-       confirm or refute it.
-
-    2. PROBE EXECUTOR -- runs every proposed probe directly against the
-       audit-mcp HTTP surface via ``AuditMcpBridgeTool``. Pure mechanical
-       execution; no reasoning step here, so the verifier cannot drift.
-
-    3. VERDICT LLM call -- given each precondition + the raw probe output,
-       classifies the precondition as ``true | false | unknown`` and then
-       emits an overall verdict ``confirmed | refuted | inconclusive``
-       with a counter-evidence narrative when refuted.
-
-    4. PERSIST -- writes ``verifier_report`` into the canonical outcome's
-       payload alongside ``panel_summary``. The frontend surfaces the
-       refuted/inconclusive verdict as a visible warning so the operator
-       doesn't trust a false-positive finding by default.
-
-This catches the two false-positive classes we hit on the nginx variant
-hunts (investigations e4e4d474 and 65505622):
-
-    - "shape predicate matches the parent CVE" without verifying the
-      preconditions are actually reachable in the audited bytecode array
-    - "no per-iteration reset of state X carries across iterations"
-      without verifying that any opcode actually mutates X in that array
-
-Both finalised with strong-confidence false-positives that a single
-counter-evidence probe (``compile_args = 1`` callsite search; opcode
-emission grep) would have killed.

-
-You are given a finding produced by a panel of reasoning agents about a

-is wrong until you have proven otherwise from the source. Your job is
-to enumerate the falsifiable preconditions the finding depends on,
-then for each one propose ONE audit_mcp tool call whose result would
-REFUTE that precondition if the panel is wrong.
-
-Walk these four questions BEFORE you write a precondition:
-  A. **Open the cited code.** What does it actually do? The panel's
-     description is a claim, not evidence -- re-read the cited function
-     body or line and state what you actually see.
-  B. **Walk the call chain outward.** Who calls the cited code, and
-     does the data really arrive there from an external entry point?
-     A precondition that asserts the entry point exists is one of the
-     load-bearing ones; pick a probe that returns ZERO matches if no
-     caller reaches it.
-  C. **Try to kill the finding.** Look for input validation,
-     allow-lists, framework escapes, type guards, platform defaults
-     (Android manifest, network_security_config), and authn/authz
-     gates that sit between source and sink. Each defense you can
-     name becomes a candidate precondition: "no defense X exists
-     between source and sink".
-  D. **Probe the defense once you find one.** If a defense exists,
-     does it cover every route into the sink, or just the one the
-     panel read? Edge cases (encoding tricks, nulls, oversized
-     values, alternative call chains) bypass partial defenses; the
-     "no edge-case bypass" assertion is a precondition with its own

-Rules:
-  - 3 to 6 preconditions. Be selective; pick the load-bearing ones.
-  - ``rank`` is a 1-based importance ordinal: 1 = most load-bearing,
-    2 = next most load-bearing, etc. Output as many preconditions as
-    are warranted by the finding -- the executor runs at most the top
-    8 by rank, so put the load-bearing ones first by ``rank``. Rank
-    ties are broken by output order.
-  - Each ``probe`` must be a real audit-mcp tool (search_source,
-    search_macros, read_function, search_constants, callers_of,
-    callees_of, etc.). Use ``$INDEX_ID`` as a literal placeholder for
-    the index -- the executor substitutes the real id.
-  - Prefer probes that, if they return ZERO matches, would refute the
-    precondition. The whole point is asymmetric refutation.
-  - **CRITICAL -- probe sizing rule**: when verifying whether a SPECIFIC
-    PATTERN (e.g. `sc.complete_lengths = 1`, `mark_args_code`, an
-    `if (x->is_args)` gate) is present or absent inside a function,
-    ALWAYS use `search_source` with the exact pattern -- NEVER use
-    `read_function`. `read_function` returns the whole function body
-    and a 500-line function's body will not fit in the verifier's
-    per-probe budget; the load-bearing region almost always lives in
-    the middle or end of large functions, gets truncated, and the
-    verifier returns inconclusive when it should return refuted.
-    `search_source` returns one line per match -- bounded, cheap,
-    diagnostic. Only fall back to `read_function` when the
-    precondition is about overall function structure (e.g. "function
-    is short enough that no missing-counterpart can hide") rather
-    than about a specific pattern.
-  - Examples of high-value precondition shapes:
-      * "Opcode X is reachable from bytecode Y because callsite Z sets
-        sc.compile_args = 1" → probe: search_source for
-        'compile_args = 1' across the file containing the relevant
-        init_params function.
-      * "Function F is missing the per-iteration reset of e->is_args" →
-        probe: search_source for `e->is_args = 0` scoped to F's file.
-      * "Block X does NOT set sc.complete_lengths" → probe:
-        search_source for `complete_lengths` scoped to F's file (NOT
-        read_function on the wrapper -- too long to fit).
-      * "Macro M expands to a length-prefix write" → probe:
-        search_macros for M.
-      * "Decompiled JS slice at `react/slices/slice_NNNNN_*.js`
-        contains the literal string `<token-shaped value>` near
-        an `Original name: <fn>` marker" → probe: read_lines on

-"""ClaimVerifierAgent -- adversarial verification of canonical-outcome claims.
-
-Runs AFTER the synthesis agent has consolidated the deliberation panel
-into a single narrative. The verifier's job is the opposite of the
-deliberation panel: instead of producing a finding, it tries to REFUTE
-the finding the panel produced.
-
-The flow:
-
-    1. EXTRACTOR LLM call -- parses ``canonical_outcome.payload.answer``
-       (and ``panel_summary.narrative`` if present) into a structured list
-       of falsifiable preconditions. Each precondition carries a single
-       ``audit_mcp.<tool>(...)`` probe call whose result will either
-       confirm or refute it.
-
-    2. PROBE EXECUTOR -- runs every proposed probe directly against the
-       audit-mcp HTTP surface via ``AuditMcpBridgeTool``. Pure mechanical
-       execution; no reasoning step here, so the verifier cannot drift.
-
-    3. VERDICT LLM call -- given each precondition + the raw probe output,
-       classifies the precondition as ``true | false | unknown`` and then
-       emits an overall verdict ``confirmed | refuted | inconclusive``
-       with a counter-evidence narrative when refuted.
-
-    4. PERSIST -- writes ``verifier_report`` into the canonical outcome's
-       payload alongside ``panel_summary``. The frontend surfaces the
-       refuted/inconclusive verdict as a visible warning so the operator
-       doesn't trust a false-positive finding by default.
-
-This catches the two false-positive classes we hit on the nginx variant
-hunts (investigations e4e4d474 and 65505622):
-
-    - "shape predicate matches the parent CVE" without verifying the
-      preconditions are actually reachable in the audited bytecode array
-    - "no per-iteration reset of state X carries across iterations"
-      without verifying that any opcode actually mutates X in that array
-
-Both finalised with strong-confidence false-positives that a single
-counter-evidence probe (``compile_args = 1`` callsite search; opcode
-emission grep) would have killed.

-
-Walk these four questions BEFORE you write a precondition:

-  B. **Walk the call chain outward.** Who calls the cited code, and
-     does the data really arrive there from an external entry point?
-     A precondition that asserts the entry point exists is one of the
-     load-bearing ones; pick a probe that returns ZERO matches if no
-     caller reaches it.
-  C. **Try to kill the finding.** Look for input validation,

-Rules:
-  - 3 to 6 preconditions. Be selective; pick the load-bearing ones.
-  - ``rank`` is a 1-based importance ordinal: 1 = most load-bearing,
-    2 = next most load-bearing, etc. Output as many preconditions as
-    are warranted by the finding -- the executor runs at most the top
-    8 by rank, so put the load-bearing ones first by ``rank``. Rank
-    ties are broken by output order.
-  - Each ``probe`` must be a real audit-mcp tool (search_source,
-    search_macros, read_function, search_constants, callers_of,
-    callees_of, etc.). Use ``$INDEX_ID`` as a literal placeholder for
-    the index -- the executor substitutes the real id.
-  - Prefer probes that, if they return ZERO matches, would refute the
-    precondition. The whole point is asymmetric refutation.
-  - **CRITICAL -- probe sizing rule**: when verifying whether a SPECIFIC
-    PATTERN (e.g. `sc.complete_lengths = 1`, `mark_args_code`, an
-    `if (x->is_args)` gate) is present or absent inside a function,
-    ALWAYS use `search_source` with the exact pattern -- NEVER use
-    `read_function`. `read_function` returns the whole function body
-    and a 500-line function's body will not fit in the verifier's
-    per-probe budget; the load-bearing region almost always lives in
-    the middle or end of large functions, gets truncated, and the
-    verifier returns inconclusive when it should return refuted.
-    `search_source` returns one line per match -- bounded, cheap,
-    diagnostic. Only fall back to `read_function` when the
-    precondition is about overall function structure (e.g. "function
-    is short enough that no missing-counterpart can hide") rather
-    than about a specific pattern.
-  - Examples of high-value precondition shapes:
-      * "Opcode X is reachable from bytecode Y because callsite Z sets
-        sc.compile_args = 1" → probe: search_source for
-        'compile_args = 1' across the file containing the relevant
-        init_params function.
-      * "Function F is missing the per-iteration reset of e->is_args" →
-        probe: search_source for `e->is_args = 0` scoped to F's file.
-      * "Block X does NOT set sc.complete_lengths" → probe:
-        search_source for `complete_lengths` scoped to F's file (NOT
-        read_function on the wrapper -- too long to fit).
-      * "Macro M expands to a length-prefix write" → probe:
-        search_macros for M.
-      * "Decompiled JS slice at `react/slices/slice_NNNNN_*.js`
-        contains the literal string `<token-shaped value>` near
-        an `Original name: <fn>` marker" → probe: read_lines on

-Default stance: the panel that proposed this finding was wrong until
-the probe results force you to conclude otherwise. Your job is NOT to
-ratify the panel; it is to actively search for the verdict that
-disagrees with them and only fall back to "confirmed" when no
-disagreement survives the probes.
-
-Decision rule:
-  - **confirmed** -- every load-bearing precondition returned `true`,
-    AND every load-bearing precondition reached an external entry
-    point, AND no probe revealed an upstream defense that fully
-    neutralizes the source-to-sink flow.
-  - **refuted** -- at least one load-bearing precondition returned
-    `false`, OR a probe revealed an upstream defense that closes
-    every route into the sink. The finding cannot survive the
-    falsification.
-  - **inconclusive** -- probes returned `unknown` on the load-bearing
-    preconditions and the source you read does not let you decide
-    either way. Say so plainly; do not default to "confirmed" out of
-    caution toward the panel.
-
-Confidence anchor (gates the operator's review queue priority):

-    via the probe set, found no surviving counter-claim, and the
-    probes covered every load-bearing precondition with at least one
-    `true`/`false` result (no `unknown` left on a load-bearing one).
-  - **0.7 to 0.89** -- verdict is well-supported but one load-bearing
-    probe returned `unknown` or the source had a region the probe
-    couldn't fully reach. State which one in `counter_evidence` or
-    `summary`.
-  - **0.5 to 0.69** -- multiple load-bearing probes returned
-    `unknown`, OR the source surface is too large for the probe set
-    to cover. The verdict is your best read but you are guessing on
-    at least one axis; say so explicitly in `summary`.

-    unknown / partial data).
-  - "confirmed" when all probes either returned true OR returned
-    unknown but the load-bearing ones returned true.
-  - Be honest about disagreement with the panel. The panel can be
-    wrong; that's why you exist. A verdict that ratifies the panel
-    when the probe set did not actively search for refutation is
-    less useful than an `inconclusive` that names what's missing.
-  - Decompiler pseudo-code IS valid probe evidence. Register-
-    machine output from Hermes-dec (`r1 = r2.setItem;
-    r4 = r5.bind(r0)(r3)`) has opaque control flow, but the
-    literal string constants, the `// Original name: <fn>,
-    environment: ...` comments above closure bodies, and the
-    `NativeModules.<Module>` access pattern survive the
-    decompile intact. When a probe reads a `react/slices/*.js`
-    file and the literal/marker the panel cited is present at
-    the cited range, that is `result: "true"` -- do not downgrade
-    to "unknown" just because the surrounding pseudo-code looks
-    generated. The asymmetric inverse also holds: when the cited

-        New shape: KEEP BOTH ROWS. The original assessment_report row
-        stays untouched in terms of ``outcome_kind`` / ``dispatch_status``;
-        a NEW direct_finding row is inserted with ``state='approved'``

-        ``promoted_to`` block so the audit trail is bi-directional. The

-
-        Choice: approach (a) keep-both-rows rather than (b) alembic
-        migration adding a ``promoted_kind`` column. Alembic on a hot
-        outcomes table during a release wave is heavier than a logical

+"""Shared ClaimVerifierAgent (RFC-03 Phase 5).
+
+``ClaimVerifierAgentBase.run`` is the three-stage adversarial verifier:
+extractor LLM parses the canonical outcome into falsifiable
+preconditions, the probe executor runs each precondition's audit-mcp
+probe in parallel, and the verdict LLM classifies the finding as
+``confirmed`` / ``refuted`` / ``inconclusive`` against the raw probe
+output. Both LLM stages route through :func:`idempotent_llm_call` so a
+worker retry replays the cached decision instead of double-paying the
+model.
+
+The vr and malware modules ship byte-identical helper bodies (prompt
+texts, probe allowlist, signature fetcher, probe payload renderer,
+precondition/verdict parsers, verdict prompt renderer, verifier report
+shape, revert-auto-promote body). They diverge on:
+
+* task-type routing keys (per-module cost / rate-limit routing),
+* the negative-finding phrase tables (VR carries the vr vocabulary,
+  malware adds a superset of malware-domain terms),
+* the record models used in the UoW SELECTs,
+* how the extractor claim text is derived from the canonical payload
+  (VR reads ``payload["answer"]``; malware routes through
+  ``render_outcome_claim_text`` because its payload is per-kind typed),
+* the auto-promote gate (VR promotes ASSESSMENT_REPORT ->
+  DIRECT_FINDING; malware promotes ANALYSIS_REPORT -> ANALYSIS_REPORT),
+* which text feeds ``is_negative_finding_claim`` on the promote path
+  (VR: ``payload["answer"]``; malware: ``payload["summary"]`` +
+  ``payload["report_body"]``),
+* malware short-circuits on ``NON_VERIFIABLE_OUTCOME_KINDS`` and adds
+  the outcome-kind line to the extractor prompt.
+
+Everything else is shared and lifted verbatim; per-module divergences
+are expressed as class attributes and small hook methods that each
+thin subclass overrides. Both module wrappers keep the
+``ClaimVerifierAgent`` class name so aggregator re-exports and
+``from aila.modules.<mod>.agents.claim_verifier import ClaimVerifierAgent``
+sites keep working.

+
+You are given a finding produced by a panel of reasoning agents about a
+specific vulnerability claim in source code. Default stance: the panel
+is wrong until you have proven otherwise from the source. Your job is
+to enumerate the falsifiable preconditions the finding depends on,
+then for each one propose ONE audit_mcp tool call whose result would
+REFUTE that precondition if the panel is wrong.
+
+Walk these four questions BEFORE you write a precondition:
+  A. **Open the cited code.** What does it actually do? The panel's
+     description is a claim, not evidence -- re-read the cited function
+     body or line and state what you actually see.
+  B. **Walk the call chain outward.** Who calls the cited code, and
+     does the data really arrive there from an external entry point?
+     A precondition that asserts the entry point exists is one of the
+     load-bearing ones; pick a probe that returns ZERO matches if no
+     caller reaches it.
+  C. **Try to kill the finding.** Look for input validation,
+     allow-lists, framework escapes, type guards, platform defaults
+     (Android manifest, network_security_config), and authn/authz
+     gates that sit between source and sink. Each defense you can
+     name becomes a candidate precondition: "no defense X exists
+     between source and sink".
+  D. **Probe the defense once you find one.** If a defense exists,
+     does it cover every route into the sink, or just the one the
+     panel read? Edge cases (encoding tricks, nulls, oversized
+     values, alternative call chains) bypass partial defenses; the
+     "no edge-case bypass" assertion is a precondition with its own
+     probe.

+}
+
+Rules:
+  - 3 to 6 preconditions. Be selective; pick the load-bearing ones.
+  - ``rank`` is a 1-based importance ordinal: 1 = most load-bearing,
+    2 = next most load-bearing, etc. Output as many preconditions as
+    are warranted by the finding -- the executor runs at most the top
+    8 by rank, so put the load-bearing ones first by ``rank``. Rank
+    ties are broken by output order.
+  - Each ``probe`` must be a real audit-mcp tool (search_source,
+    search_macros, read_function, search_constants, callers_of,
+    callees_of, etc.). Use ``$INDEX_ID`` as a literal placeholder for
+    the index -- the executor substitutes the real id.
+  - Prefer probes that, if they return ZERO matches, would refute the
+    precondition. The whole point is asymmetric refutation.
+  - **CRITICAL -- probe sizing rule**: when verifying whether a SPECIFIC
+    PATTERN (e.g. `sc.complete_lengths = 1`, `mark_args_code`, an
+    `if (x->is_args)` gate) is present or absent inside a function,
+    ALWAYS use `search_source` with the exact pattern -- NEVER use
+    `read_function`. `read_function` returns the whole function body
+    and a 500-line function's body will not fit in the verifier's
+    per-probe budget; the load-bearing region almost always lives in
+    the middle or end of large functions, gets truncated, and the
+    verifier returns inconclusive when it should return refuted.
+    `search_source` returns one line per match -- bounded, cheap,
+    diagnostic. Only fall back to `read_function` when the
+    precondition is about overall function structure (e.g. "function
+    is short enough that no missing-counterpart can hide") rather
+    than about a specific pattern.
+  - Examples of high-value precondition shapes:
+      * "Opcode X is reachable from bytecode Y because callsite Z sets
+        sc.compile_args = 1" \u2192 probe: search_source for
+        'compile_args = 1' across the file containing the relevant
+        init_params function.
+      * "Function F is missing the per-iteration reset of e->is_args" \u2192
+        probe: search_source for `e->is_args = 0` scoped to F's file.
+      * "Block X does NOT set sc.complete_lengths" \u2192 probe:
+        search_source for `complete_lengths` scoped to F's file (NOT
+        read_function on the wrapper -- too long to fit).
+      * "Macro M expands to a length-prefix write" \u2192 probe:
+        search_macros for M.
+      * "Decompiled JS slice at `react/slices/slice_NNNNN_*.js`
+        contains the literal string `<token-shaped value>` near
+        an `Original name: <fn>` marker" \u2192 probe: read_lines on
+        the slice range cited by the panel and confirm the
+        literal + the marker are both present.

+
+Default stance: the panel that proposed this finding was wrong until
+the probe results force you to conclude otherwise. Your job is NOT to
+ratify the panel; it is to actively search for the verdict that
+disagrees with them and only fall back to "confirmed" when no
+disagreement survives the probes.
+
+Decision rule:
+  - **confirmed** -- every load-bearing precondition returned `true`,
+    AND every load-bearing precondition reached an external entry
+    point, AND no probe revealed an upstream defense that fully
+    neutralizes the source-to-sink flow.
+  - **refuted** -- at least one load-bearing precondition returned
+    `false`, OR a probe revealed an upstream defense that closes
+    every route into the sink. The finding cannot survive the
+    falsification.
+  - **inconclusive** -- probes returned `unknown` on the load-bearing
+    preconditions and the source you read does not let you decide
+    either way. Say so plainly; do not default to "confirmed" out of
+    caution toward the panel.
+
+Confidence anchor (gates the operator's review queue priority):
+  - **0.9 to 1.0** -- you actively searched for the opposite verdict
+    via the probe set, found no surviving counter-claim, and the
+    probes covered every load-bearing precondition with at least one
+    `true`/`false` result (no `unknown` left on a load-bearing one).
+  - **0.7 to 0.89** -- verdict is well-supported but one load-bearing
+    probe returned `unknown` or the source had a region the probe
+    couldn't fully reach. State which one in `counter_evidence` or
+    `summary`.
+  - **0.5 to 0.69** -- multiple load-bearing probes returned
+    `unknown`, OR the source surface is too large for the probe set
+    to cover. The verdict is your best read but you are guessing on
+    at least one axis; say so explicitly in `summary`.
+  - **below 0.5** -- do NOT emit a final verdict. Return
+    `verdict: "inconclusive"` and name in `counter_evidence` exactly
+    what probe or source read would resolve it.

+    unknown / partial data).
+  - "confirmed" when all probes either returned true OR returned
+    unknown but the load-bearing ones returned true.
+  - Be honest about disagreement with the panel. The panel can be
+    wrong; that's why you exist. A verdict that ratifies the panel
+    when the probe set did not actively search for refutation is
+    less useful than an `inconclusive` that names what's missing.
+  - Decompiler pseudo-code IS valid probe evidence. Register-
+    machine output from Hermes-dec (`r1 = r2.setItem;
+    r4 = r5.bind(r0)(r3)`) has opaque control flow, but the
+    literal string constants, the `// Original name: <fn>,

+    file and the literal/marker the panel cited is present at
+    the cited range, that is `result: "true"` -- do not downgrade
+    to "unknown" just because the surrounding pseudo-code looks

+"""Shared synthesis runner (RFC-03 Phase 5).
+
+``SynthesisRunnerBase.run`` is the single per-investigation synthesis
+pipeline: load the canonical outcome, gate on already-synthesized,
+build the panel from ``panel_contributions``, call the module's
+schema-validated LLM, and commit ``panel_summary`` (plus any module-
+specific payload promotions) under a row-lock on the investigation. It
+was lifted verbatim from the byte-shared skeleton of the vr and malware
+synthesis agents; the per-module differences are expressed as class
+attributes and small override hooks that every subclass sets:
+
+* class attributes -- ``_LOG_LABEL``, ``_TASK_TYPE``, ``_SYSTEM_PROMPT``
+  (module-inline for now; RFC-09 moves prompts to the registry),
+  ``_investigation_model``, ``_outcome_model``, ``_response_model``
+  (the module's ``SynthesisResponse``), ``_branch_table`` (SQL table
+  name for orphan-branch cleanup on the status flip).
+* required hook -- ``_render_user_prompt(panel)`` builds the LLM
+  user-side prompt; vr and malware render very different persona-panel
+  shapes so this override is mandatory.
+* optional hooks with sane defaults:
+  - ``_should_force_resynthesize()`` -- default ``False``; malware
+    overrides when ``options.force`` is set so a manual re-synthesize
+    from the UI bypasses the already-synthesized + alive-status gates.
+  - ``_should_flip_investigation_status(inv_row)`` -- default ``True``;
+    malware overrides to skip the flip on force-runs against an
+    already-completed investigation.
+  - ``_build_panel_entry(contribution, canonical_payload)`` -- default
+    returns the 7 core keys used by ``synthesis_confidence`` and the
+    ``panel_summary.personas`` list; vr overrides to add
+    ``affected_components`` + ``variant_hunt_orders`` derived from the
+    canonical payload for its rendering.
+  - ``_update_payload_extras(payload, parsed)`` -- default no-op (vr
+    keeps every synthesised field inside the ``panel_summary``
+    narrative); malware overrides to promote ``family_attribution`` /
+    ``capabilities`` / ``iocs`` / ``detection_guidance`` / etc. onto
+    the top-level canonical payload so the operator card renderer and
+    downstream dispatch see the structured detail.
+
+The two UoWs (read + row-locked write) preserve the fix §160 pattern
+from both module copies: the LLM call runs outside any transaction so a
+slow model does not hold the investigation row lock, and the write path
+re-loads under ``SELECT FOR UPDATE`` so a concurrent operator pause
+cannot lose to the payload write. The DB access is factored into
+``_load_inv_and_canonical`` and ``_commit_synthesis`` so tests can
+replace them with in-memory fakes without patching ``UnitOfWork``.

+"""Characterization tests for the platform ClaimVerifier (RFC-03 Phase 5).
+
+Exercises the verifier logic for BOTH module configs (vr + malware) so
+the pre-extraction behavior is preserved. Every LLM call is mocked at
+the ``idempotent_llm_call`` seam; the DB round-trips are patched via
+``_load_context`` and a fake ``UnitOfWork`` so no migrations or infra
+are required.
+
+Coverage:
+
+  * Module class attributes bind the platform base with the right
+    task-type keys, negative-phrase tables, record models, dispatcher
+    class, and auto-promote gate constants.
+  * ``is_negative_finding_claim`` fires on module-specific vocabulary
+    (VR only rejects vr terms; malware rejects both vr and malware
+    terms) and tolerates ``None`` / empty input.
+  * ``_parse_preconditions`` and ``_parse_verdict`` tolerate fenced
+    JSON, leading / trailing prose, and return empty / ``None`` on
+    malformed LLM output.
+  * ``_render_verdict_input`` produces the labelled per-precondition
+    section with the smart probe-payload rendering + the 40000-char
+    truncation marker.
+  * ``_render_probe_payload`` dispatches on tool name for
+    ``read_function`` / ``search_source`` / ``callers_of`` and falls
+    back to ``json.dumps`` otherwise.
+  * ``_maybe_auto_promote`` short-circuits before opening a UoW when
+    confidence is non-numeric or below the module's floor (the config
+    reader is mocked via ``_read_auto_promote_floor``).
+  * The full ``run`` pipeline exercises the extractor -> probe ->
+    verdict path with all IO seams stubbed, and each early-exit path
+    (no context, already verified, malformed extractor output, kill
+    switch, malformed verdict, non-verifiable outcome kind).

+"""Characterization tests for the platform SynthesisRunner (RFC-03 Phase 5).
+
+Exercises the synthesis pipeline for BOTH module configs (vr + malware)
+so the pre-extraction behavior is preserved after the extraction. Every
+LLM call is mocked at the ``idempotent_llm_call`` seam; the DB round-
+trips are patched via ``_load_inv_and_canonical`` / ``_commit_synthesis``
+so no migrations or infra are required.
+
+Coverage:
+  * Class-attribute bindings (task_type, branch_table, response_model,
+    system prompt, investigation/outcome model) are per-module correct.
+  * Panel-entry structure: vr's ``_build_panel_entry`` overrides adds
+    ``affected_components`` + ``variant_hunt_orders`` derived from the
+    canonical payload; malware inherits the 7-core-key default.
+  * User-prompt rendering: vr surfaces persona blocks + agreement /
+    disagreement instructions; malware injects tone + length + optional
+    operator-focus + structured-schema instructions.
+  * ``_should_force_resynthesize`` returns False for vr always, and for
+    malware tracks ``options.force``.
+  * ``_should_flip_investigation_status`` returns True for vr always,
+    for malware skips only on ``force + already_completed``.
+  * ``_update_payload_extras``: vr is a no-op; malware promotes every
+    structured field (family_attribution / capabilities / iocs /
+    detection_guidance / next_actions / panel_dissent / etc.) onto
+    payload top-level with correct IOC-bucket merge semantics.
+  * ``run()`` orchestration paths: happy path, skip paths
+    (investigation_not_found, no_canonical_outcome,
+    already_synthesized, no_panel_contributions, no_valid_contributions,
+    structured_parse_failed, empty_llm_response, llm_kill_switch_active,
+    llm_error:*), and malware's force-bypass of the pre-lock
+    already_synthesized gate.
+  * ``_commit_synthesis`` under-lock behavior: alive-status gate,
+    already-synthesized-under-lock gate, force bypass, status-flip
+    hook interaction.
+
+The test parametrises on a small ``_Config`` struct so both modules run
+through the identical assertion set -- any drift between the vr and
+malware subclass classes would immediately break one variant.

Subject: [PATCH 265/281] feat(llm): record prompt_version + universal
 content-hash attribution (RFC-09)

Extends the prompt-attribution recording from the single researcher-turn
path to every agent LLM call, and adds the missing prompt_version field.

- The correlation context gains prompt_version alongside prompt_content_hash,
  with a current_prompt_version accessor. LLMCostRecord and AuditSealRecord
  gain a prompt_version column (migration 094); the cost + seal writers
  stamp it.
- idempotent_llm_call now opens a correlation scope around the model call
  with set-if-unset precedence: an explicit arg wins, then an outer scope
  (the researcher turn), then the sha256 of the system prompt. Every call
  routed through it (claim verifier, pattern extractor, synthesis, nday,
  narrative) therefore lands a content_hash on its cost + seal records
  instead of leaving them null. Callers may pass prompt_version to attribute
  a resolved version.

This closes the recording half of RFC-09 criterion 2 for the agent call
path. Routing the remaining report/workflow inline prompts through the
registry, pin-per-investigation, and the model-family key are the next
RFC-09 slices.

+"""094 -- add prompt_version to cost + seal records (RFC-09).
+
+Tags each LLM cost record and audit seal with the resolved prompt version
+(the version-store key) that produced the call, alongside the existing
+prompt_content_hash. Together they answer "which prompt, at which version,
+cost how much and produced what" without replay. Nullable: inline prompts
+with no version-store entry, and calls outside an agent turn, leave it
+unset. The agent turn loop and idempotent_llm_call set it through the
+correlation ContextVar that the cost + seal writers read. The SQLModel
+models are updated in the same commit so create_all (tests, fresh
+installs) matches the migrated schema.
+
+Guarded with IF NOT EXISTS so a re-run, or a fresh database that already
+carries the column, is a no-op.

Subject: [PATCH 266/281] feat(prompts): pin resolved prompt versions per
 investigation (RFC-09)

Closes RFC-09 criterion 4 -- a live production-alias flip no longer
re-routes a running investigation. InvestigationRecordBase gains
prompt_pins_json (migration 095, on vr_investigations + malware_
investigations), a JSON map of prompt-key -> resolved version.

resolve_pinned_prompt (new platform/prompts/pinning.py) implements lazy
pinning: the first resolve of a key for an investigation records the
current production version into the pin and uses it; every later resolve
reads the pinned version and resolves that exact version instead of the
live alias. Fail-open is preserved -- a store error or a missing
investigation falls back to the file registry, and no pin is written when
there is no production alias. Both researchers' _load_prompt return a
LoadedPrompt(body, version); turn_runner threads investigation_id in and
stamps the resolved version into the correlation scope so the cost + seal
writers record the exact version (closing the version half of criterion 2
on the researcher path).

Model-family key variants (criterion 6) are deferred: the routing layer
exposes no first-class model family to key on. Pin tests cover first-
resolve pinning, alias-flip inertness, per-investigation isolation, and
store-error fallback.

+"""095 -- add prompt_pins_json to investigations (RFC-09 criterion 4).
+
+Pins the prompt versions a running investigation resolved on its first
+turn, so a later production-alias flip does not re-route an in-flight
+investigation to a different prompt. The column lives on the shared
+InvestigationRecordBase, so both module investigation tables receive it.
+It maps prompt-key -> resolved version string; the resolve path reads the
+pin and resolves that exact version instead of the live alias, persisting
+the pin lazily on first resolve. The SQLModel base is updated in the same
+commit so create_all (tests, fresh installs) matches the migrated schema.

+3. If not pinned, resolve the current ``production`` alias. When a
+   version comes back, persist ``{key: version}`` into the row's pin map
+   in a single UPDATE and return that body + version.
+4. When the store raises (fail-open), or the alias points at nothing,

Subject: [PATCH 267/281] refactor(prompts): route report/workflow prompts
 through the registry (RFC-09)

Closes RFC-09 criterion 1 for the six LLM call sites that do not go
through idempotent_llm_call: the human-cost estimator, the VR section
writer, the VR advisory-narrative and PoC-development workflow states, and
the forensics writeup builder + free-flow investigator. Each inline system
-prompt literal moves to a .md file resolved through the file-backed
PromptRegistry (byte-identical to the prior text, verified, so no cost or
seal drift), and each LLM call is wrapped in a correlation scope that
stamps sha256(prompt) while preserving any outer investigation/branch/turn/
prompt_version attribution. The forensics free-flow prompt keeps its OS-
hint assembly in code over base + per-OS .md fragments, hashing the final
assembled prompt. These sites now record content_hash on their cost + seal
records instead of leaving them null.

The agent-reasoning prompts still held as class attrs on the platform
ClaimVerifier/Synthesis/PatternExtractor bases route through
idempotent_llm_call (already content-hash-stamped) and remain a criterion-1
follow-up.

-Rules:
-- The ONLY way to finalise an answer is action="submit" with a non-null
-  "answer", "confidence" in {exact, strong, medium, caveated}, AND a
-  non-empty "provenance.primary_artifact" that was either produced by a
-  prior turn's tool output OR already exists in the artefacts snapshot.
-- Never submit on the first turn unless the artefacts snapshot already
-  contains a direct match for the question wording AND you cite it.
-- If the cheapest high-information-gain action is a script, emit it.
-  Prefer concrete primitives (dissect.target, volatility3, tshark,
-  strings, sha256sum, pylnk3, ELF parsing) over shell guesswork.
-- Do NOT retry a command that failed the same way in a prior turn.
-- Before writing a new script, check if the information already exists in
-  project artifacts: use action="artifact_query" with "command" set to a
-  search string (IP, hostname, hash, filename, registry key). This is FREE
-  (no SSH, no script execution) and returns structured data instantly.
-  Set observables._artifact_family or _artifact_type to filter by category.
-- "rejected" carries hypotheses you have eliminated with evidence. Always
-  carry prior rejects forward so the agent doesn't re-explore dead ends.
-- "observables" is cumulative: include new facts AND any you want to
-  preserve. Fields should be normalised key=value pairs like
-  `executed_file=main.exe`, `c2=100.103.254.83:50051`, `syscall_hooked=__x64_sys_kill`.
-
-Static analysis only (NON-NEGOTIABLE):
-- AILA operates on read-only copies of evidence. You MUST NOT:
-    * Execute the sample, its droppers, or any artefact extracted from
-      the evidence -- no `rundll32`, `regsvr32`, `mshta`, `wscript`,
-      `cscript`, `msiexec`, `wine`, `mono`, `./a.out`, `./sample`, no
-      invocation of any PE, ELF, script, or LNK recovered from disk.
-    * Connect to, probe, scan, or name-resolve any IP, domain, URL, or
-      hostname observed in the evidence -- no `curl`, `wget`, `ncat`,
-      `nc`, `ssh`, `ftp`, `telnet`, `Invoke-WebRequest`, no
-      `ping`/`tracert`, no `nmap`/`masscan`, no `nslookup`/`dig`/`whois`
-      against an IOC.
-    * Import Python networking modules (`socket`, `http`, `urllib`,
-      `requests`, `ftplib`, `smtplib`) or use dynamic Python evaluation
-      (`exec`, `eval`, `__import__`). `os.popen`, `os.system`, and
-      `subprocess.*` are permitted for static tooling, but every shell
-      command they launch is still subject to the command blocklist --
-      no network fetchers, no sample detonation, no container starts.
-    * Start containers, VMs, or emulators -- anything that would execute
-      untrusted code.
-- Legitimate analysis actions are: file read, hash, parse (dissect.target,
-  volatility3, tshark, pylnk3, YARA, `magic.from_file`), decode, string
-  extraction, decompilation (capa, Ghidra headless artefacts already on
-  record), regex/AST search, memory carve, byte-offset reporting. These
-  stay entirely on-disk.
-- If a sample resists static techniques (packed binary whose static
-  strings are unhelpful), record the limitation in `observables.gaps.*`
-  and propose alternative static paths (FLOSS, capa, static unpacking,
-  memory-dump analysis of a PRE-EXISTING dump). Do NOT propose running
-  the sample.
-- Any script or command that matches the prohibition list is refused by
-  the executor before it reaches the analyzer. Refused attempts do NOT
-  count as evidence of "not present" -- they are policy refusals.
-
-File classification rule (CRITICAL -- applies to every turn):
-- NEVER classify a file by its extension. Always classify by content
-  using the `python-magic` library, which wraps libmagic and returns
-  authoritative type strings derived from the full file-type database:
-
-      import magic
-      desc = magic.from_file(path)          # human-readable description
-      mime = magic.from_file(path, mime=True)  # MIME type
-
-  Examples of what `python-magic` returns (do NOT hand-roll these):
-      "PE32+ executable (GUI) x86-64, for MS Windows" / "application/x-dosexec"
-      "ELF 64-bit LSB shared object, x86-64"          / "application/x-sharedlib"
-      "Zip archive data, at least v2.0 to extract"    / "application/zip"
-      "MS Windows shortcut"                           / "application/x-ms-shortcut"
-      "PDF document, version 1.4"                     / "application/pdf"
-      "Composite Document File V2 Document, ..."      / "application/x-ole-storage"
-      "POSIX tar archive"                             / "application/x-tar"
-      "gzip compressed data, from Unix"               / "application/gzip"
-
-  For in-memory bytes (e.g. after a raw-carve or ZIP member read):
-      desc = magic.from_buffer(data[:8192])
-
-- A file whose extension suggests an image but whose libmagic
-  description is a different type (e.g. "MS Windows shortcut", "PE32")
-  is the libmagic-derived type, not the extension. Attackers routinely
-  disguise entry-point files this way -- trust libmagic, not the
-  extension.
-- When reporting `answer_type=extension`, the answer must match the
-  libmagic-derived type of the OUTERMOST trigger file (the one a victim
-  would double-click). For disguised files submit the TRUE extension
-  implied by the libmagic description (e.g. `.lnk` when the description
-  contains "shortcut", `.exe` when it contains "PE32", `.hta` when it
-  contains "HTML Application"), and record the disguise in
-  `provenance.rejected_alternatives`.
-
-Entry-point suspicion heuristic (CRITICAL -- the agent's failure mode
-has been overlooking an obvious .lnk/.hta/.iso because its default
-handler looks normal):
-- A file is a PROBABLE execution trigger when ANY of these signals
-  hold, independent of the system's default handler for that extension:
-    * It sits inside an archive (.zip, .rar, .7z, .iso, .cab, .msi)
-      that was received from outside the machine (downloaded, mailed,
-      USB-dropped), AND the archive was recently accessed
-      (RecentDocs / shellbags / UserAssist / Prefetch evidence).
-    * It uses a DOUBLE EXTENSION or spoofed extension
-      (e.g. `invoice.pdf.lnk`, `photo.jpg.exe`, `document.docx.hta`,
-      `musk.jpg.lnk`). Attackers rely on default Explorer hiding the
-      trailing "real" extension.
-    * Its libmagic description is one of:
-        "MS Windows shortcut"         (.lnk)
-        "HTML Application"            (.hta)
-        "Microsoft Windows script"    (.vbs, .js, .wsf)
-        "Microsoft Cabinet archive"   (.cab)
-        "ISO 9660 / UDF filesystem"   (.iso / .img -- common ISO
-                                      smuggling of embedded .lnk)
-        "PE32" in a file whose name ends with .jpg/.png/.pdf/.docx
-      AND it co-locates (same folder) with one or more of:
-        - a named PE (main.exe, server.exe, loader.exe),
-        - a batch/PowerShell helper (run.bat, go.ps1, start.cmd),
-        - a decoy image (img.jpg, photo.jpg),
-        - a uuid.txt / token / key file.
-      That co-location pattern is the classic ISO/ZIP-smuggled LNK
-      dropper bundle. Score it HIGH even if the .lnk handler shown in
-      the registry is the stock Windows default -- the shortcut's
-      TARGET is what matters, not the extension handler.
-- When you see a candidate entry-point file, IMMEDIATELY:
-    1. Classify with `magic.from_file(path)` + MIME.
-    2. If it is a .lnk, parse the shortcut with the `pylnk`
-       library (from `liblnk-python`, already installed). Minimal
-       usage:
-
-           import pylnk
-           lnk = pylnk.open(path_to_lnk)
-           print("name            :", lnk.name)
-           print("local_path      :", lnk.local_path)
-           print("relative_path   :", lnk.relative_path)
-           print("working_dir     :", lnk.working_directory)
-           print("cmdline_args    :", lnk.command_line_arguments)
-           print("description     :", lnk.description)
-           print("icon_location   :", lnk.icon_location)
-           lnk.close()
-
-       The `command_line_arguments` field usually contains the real
-       command (e.g. `cmd.exe /c start run.bat` or an encoded
-       PowerShell one-liner). Fall back to `pylnk.open_file_object`
-       with a `BytesIO` when the .lnk is inside a ZIP/ISO and you
-       extracted it in-memory.
-    3. Record `observables.trigger_file=<name>`,
-       `observables.trigger_magic=<libmagic-desc>`,
-       `observables.trigger_target=<lnk-target-or-script-body>`.
-    4. Set `provenance.primary_artifact` to the trigger file path.
-- Do NOT dismiss a .lnk on the grounds that "the Windows .lnk handler
-  is normal". The .lnk extension IS the trigger; the payload is the
-  TARGET encoded inside the shortcut.
-
-Evidence mapping rule (CRITICAL):
-- The question may name a specific disk/image/memory/pcap. You MUST
-  map that name to the correct file in the Evidence files listing
-  BEFORE choosing an
-  action. Do NOT pivot to a different evidence file just because prior
-  artefacts came from elsewhere -- prior artefacts may be from unrelated
-  collections on the same project.
-- If the named evidence file is a Linux disk image and prior artefacts
-  are Windows-flavoured, trust the file, not the artefacts. Linux disk
-  evidence calls for Linux-native investigation (kernel modules, init
-  systems, cron, bash history, systemd timers, /etc, /home, /root,
-  /var/log, shadow/passwd, persistence via LD_PRELOAD, rootkit
-  indicators, SUID binaries).
-- Test-open the named disk with dissect.target first and print
-  `target.os`, filesystems, and a top-level `/` listing before any deep
-  search. That single observation tells you whether the disk is
-  Linux/Windows/other and guides every subsequent action.

-Malformed-data recovery rule (CRITICAL -- applies to EVERY parse step):
-- A parse failure (JSON, YAML, XML, sqlite, plist, registry hive, evtx,
-  pcap, archive, ELF/PE) is NEVER a final answer. The string "could
-  not be parsed" / "JSON error" / "decode error" / "unexpected EOF"
-  in your output table is a forbidden conclusion. If you wrote it,
-  you must immediately re-attempt with the recovery ladder below
-  before accepting the result.
-- Recovery ladder (try in order, stop at first success):
-    1. STRICT then LENIENT JSON. After `json.load`/`json.loads` fails:
-         a. Read the raw bytes and print the offending offset:
-              raw = Path(p).read_bytes()
-              print("size:", len(raw), "first 200B:", raw[:200])
-              print("last 200B:", raw[-200:])
-              try:
-                  json.loads(raw.decode("utf-8", errors="replace"))
-              except json.JSONDecodeError as e:
-                  print("err:", e, "at line", e.lineno, "col", e.colno,
-                        "char", e.pos)
-                  print("ctx:", raw.decode("utf-8", errors="replace")
-                        [max(0,e.pos-80):e.pos+80])
-         b. Try `json5` (handles trailing commas, comments, single
-            quotes, unquoted keys). If `json5` is missing, install via
-            `pip install json5` is BLOCKED (no network) -- instead use
-            the manual fixups below.
-         c. Manual fixups, applied in sequence, each followed by
-            another `json.loads` attempt:
-              - Strip trailing commas:  re.sub(r",(\\s*[}\\]])", r"\\1", t)
-              - Strip JS-style comments: re.sub(r"//[^\\n]*", "", t)
-                                         re.sub(r"/\\*.*?\\*/", "", t,
-                                                flags=re.DOTALL)
-              - Replace single with double quotes (only when no embedded
-                doubles): t.replace("'", '"')
-              - Append a closing `}` or `]` if the file is truncated
-                (use `e.pos == len(raw)` as the signal).
-              - Strip BOM:  raw.lstrip(b"\\xef\\xbb\\xbf").decode("utf-8")
-         d. If still failing, parse line-by-line as **JSON Lines**
-            (one object per line). Many "JSON" files are actually
-            NDJSON / JSONL streams concatenated.
-         e. If still failing, the file may be JSONP, a JS module, or
-            a key=value config disguised by extension. Confirm with
-            `magic.from_file(path)` and switch parser accordingly.
-         f. Last resort: regex out the fields the question actually
-            needs (e.g. `re.findall(r'"contributors"\\s*:\\s*\\[(.*?)\\]',
-            text, re.DOTALL)`) and report them with
-            `confidence="caveated"` plus a note about the parse failure.
-    2. YAML: try `yaml.safe_load` then `yaml.unsafe_load` (PyYAML is
-       installed). For multi-doc files iterate `yaml.safe_load_all`.
-    3. XML: switch from `xml.etree.ElementTree` to `lxml.etree`
-       with `recover=True` -- recovers from unclosed tags, bad
-       encoding, mixed declarations.
-    4. SQLite: open with `sqlite3.connect(path)` then run
-       `PRAGMA integrity_check;`. For corrupt DBs use the `.recover`
-       command via `sqlite3` CLI or read raw with the `simplekv`
-       byte-level walk.
-    5. Registry hives: when `dissect.regf` rejects a hive, try
-       `python-registry` (`from Registry import Registry`) which is
-       more permissive on dirty hives. Always inspect `*.LOG1`/`*.LOG2`
-       transaction files alongside the hive.
-    6. Archives: when stdlib `zipfile` raises BadZipFile, scan for
-       extra ZIP central-directory signatures (PK\\x05\\x06) deeper in
-       the file -- many "broken" zips are valid zips with a prefix
-       (e.g. polyglots, self-extractors). `zipfile.ZipFile(BytesIO(
-       raw[offset:]))` from the discovered offset usually works.
-    7. PE/ELF: when `pefile` / `lief` reject a binary, dump strings
-       and run `capa` against the raw bytes; capa tolerates malformed
-       headers far better than the structured parsers.
-    8. RAW FILE READ failures (UnicodeDecodeError, "content not
-       recovered", "could not read", "encoding error", PermissionError):
-       text decode is NEVER the right first move on forensic data.
-       The recovery ladder for any read failure is:
-         a. Confirm the file exists, its size, and its libmagic type:
-              p = Path(path)
-              print("exists:", p.exists(), "size:", p.stat().st_size if
-                    p.exists() else "n/a")
-              import magic
-              print("magic:", magic.from_file(str(p)))
-              print("mime :", magic.from_file(str(p), mime=True))
-         b. Read as BYTES first, never as text:
-              raw = Path(path).read_bytes()
-              print("first 256B hex:", raw[:256].hex())
-              print("first 512B (lossy):",
-                    raw[:512].decode("utf-8", errors="replace"))
-            `errors="replace"` (or `errors="ignore"`) NEVER raises and
-            always returns something useful. There is no excuse for an
-            empty result row when this primitive exists.
-         c. Try alternate encodings in order: utf-8, utf-16-le,
-            utf-16-be, utf-8-sig (BOM), cp1252, latin-1. `latin-1`
-            decodes ANY byte sequence -- use it as a guaranteed
-            last-resort textualisation:
-              text = raw.decode("latin-1")
-         d. If libmagic says "data" / "binary" / "compressed",
-            switch tactics: don't try to "read" it as text at all.
-            Run `strings -a -n 4 path` (or the Python equivalent
-            `re.findall(rb"[\\x20-\\x7e]{4,}", raw)`) and grep for
-            keys/IDs/timestamps the question asks about.
-         e. If the file is HELD OPEN by another process (sqlite WAL,
-            eventlog .evtx, registry hive in use): copy the bytes
-            with `shutil.copy2` first into %TEMP%, then read the copy.
-            For evtx specifically use `python-evtx` (already installed
-            as `Evtx`); never try `read_text` on a .evtx.
-         f. If a structured-log file (.log, .jsonl, .ndjson, .csv,
-            .tsv) fails to decode mid-stream, read in BINARY chunks
-            and process line-by-line, dropping bad lines:
-              kept, bad = 0, 0
-              with open(path, "rb") as fh:
-                  for line in fh:
-                      try:
-                          rec = line.decode("utf-8")
-                      except UnicodeDecodeError:
-                          bad += 1
-                          continue
-                      kept += 1
-                      ... # process rec
-              print(f"kept={kept} dropped={bad}")
-         g. For application logs whose extension lies (.logs that's
-            actually a sqlite, a protobuf, a gzipped stream, a
-            rotated tar) trust libmagic from step (a) and switch
-            parser:
-              gzip → `gzip.open(path, "rt", errors="replace")`
-              sqlite → `sqlite3.connect(path)` + `.tables`
-              protobuf → dump strings + `protoc --decode_raw`
-              tar/zip → extract first, then iterate members.
-- Only after the ladder is exhausted may you describe the file as
-  unparseable, and then ONLY in `provenance.rejected_alternatives`
-  with explicit recovery attempts listed. The `Confidence` column of
-  any conclusion MUST cite the recovery path used (e.g.
-  "JSONL fallback after strict-JSON failure", or
-  "latin-1 + strings extraction after utf-8 decode failure").
-- Forbidden phrases in your final answer / observables / writeup:
-  "could not be parsed", "JSON error", "could not extract",
-  "could not be recovered", "content not recovered",
-  "binary-safe encoding required", "manual inspection required" --
-  without an accompanying recovery-attempt log showing AT LEAST steps
-  (a) and (b) of the appropriate ladder. These phrases without that
-  log are a sign the agent gave up early and the row is invalid.
-
-Partial-read completion rule (CRITICAL -- applies to EVERY data
-gathering step, not just parse failures):
-- "Not fully extracted", "first N entries shown", "log body
-  truncated", "subdirectory logs not read", "first chunk only",
-  or any phrasing implying you saw SOME data and stopped, is NEVER
-  a final answer. A row in your output table that says "X not fully
-  extracted" obliges you to re-run with the completion ladder below
-  before submitting.
-- WHY truncation happens here:
-    * Tool stdout is now capped at 512 KB per turn; anything past
-      that comes back with the explicit
-      `...[truncated N more bytes -- re-run with grep/head/tail]`
-      marker. That marker is an INSTRUCTION, not a finding.
-    * You may have iterated only the first 3-5 entries of an archive
-      / log directory / SQL result and forgotten the tail.
-    * You may have passed `head -n 20` / `[:20]` / `LIMIT 20` and
-      reported the trimmed view as the whole answer.
-- Completion ladder (apply whichever fits the situation):
-    1. CHUNKED READ (single huge file). Read in fixed windows and
-       process each window before moving on:
-           OFFSET = 0
-           CHUNK  = 256 * 1024  # 256 KB per turn fits comfortably
-           with open(path, "rb") as fh:
-               fh.seek(OFFSET)
-               buf = fh.read(CHUNK)
-           print(f"BYTES {OFFSET}..{OFFSET+len(buf)} of {Path(path).stat().st_size}")
-           # process buf, then on the next turn pass OFFSET += CHUNK
-       Track progress in `observables.read_offset_<filename>` so the
-       next turn knows where to resume. Stop only when
-       `OFFSET >= file_size`.
-    2. TARGETED EXTRACTION (huge file, narrow question). Don't read
-       the whole thing -- `grep -n -E 'pattern' path | head -n 200`,
-       or in Python:
-           import re
-           hits = []
-           with open(path, "r", errors="replace") as fh:
-               for n, line in enumerate(fh, 1):
-                   if re.search(r"<your-pattern>", line):
-                       hits.append((n, line.rstrip()))
-           print(f"matches: {len(hits)}")
-           for h in hits[:200]:
-               print(h)
-    3. LOG-FAMILY ENUMERATION (CI/CD or service log bundles). When
-       the question concerns "what the pipeline did" /
-       "what was deployed" / "which step failed", iterate EVERY log
-       in the bundle, not just the top-level. Standard layouts:
-         GitHub Actions  →  `<run>/<job>/<step>_<name>.txt`
-         Azure DevOps    →  `logs/<jobid>/<step-N>_<name>.log`
-         Jenkins         →  `builds/<n>/log` and `branches/*/builds/*/log`
-         GitLab CI       →  `<job>/<step>.log`
-       Recipe:
-           from pathlib import Path
-           ROOT = Path(r"<bundle-root>")
-           logs = sorted(p for p in ROOT.rglob("*")
-                         if p.is_file()
-                         and p.suffix.lower() in {".txt", ".log"})
-           print(f"LOGS: {len(logs)}")
-           for p in logs:
-               sz = p.stat().st_size
-               head = p.read_bytes()[:400].decode("utf-8", errors="replace")
-               print(f"\\n=== {p.relative_to(ROOT)} ({sz} B) ===")
-               print(head)
-           # Then deep-read each one whose head matches the question
-           # using the chunked recipe in (1).
-       Specifically: a row that says "Read 0_build-and-deploy.txt and
-       subdirectory logs individually" is a TODO directed at YOU. Do
-       not write it as a finding -- execute it.
-    4. ARCHIVE-INTERIOR ENUMERATION. Never report on "the .zip"
-       without iterating EVERY member:
-           with zipfile.ZipFile(path) as zf:
-               members = zf.infolist()
-               print(f"MEMBERS: {len(members)}")
-               for m in members:
-                   print(f"  {m.filename}  {m.file_size} B")
-                   if m.file_size < 256 * 1024:
-                       data = zf.read(m).decode("utf-8", errors="replace")
-                       print(data[:1000])
-    5. DIRECTORY ENUMERATION. Never conclude "the folder contains
-       config files" from `ls`. Use:
-           paths = sorted(Path(root).rglob("*"))
-           print(f"FILES: {sum(1 for p in paths if p.is_file())}")
-           for p in paths:
-               if p.is_file():
-                   print(f"  {p.relative_to(root)}  {p.stat().st_size} B")
-       and then deep-read each one the question targets.
-    6. PAGINATED RESULT SETS (sqlite, evtx, json arrays). Use OFFSET
-       /LIMIT or generator-style iteration, NOT `LIMIT 20`. Persist
-       the cursor in `observables`.
-- A finding row whose `Status` is "incomplete" / "partial" /
-  "needs more reading" / "not fully extracted" / a `Suggested next
-  step` that paraphrases the obvious next read is forbidden. Either:
-    a) execute the next read in the SAME or NEXT turn and replace
-       the row with the completed result, or
-    b) explain in `provenance.rejected_alternatives` why the read
-       was infeasible, with the chunked attempt
-       proven by your output.
-- The `Suggested next step` column of any results table is only
-  legitimate when paired with concrete blockers. "Read X individually"
-  is not a blocker; it is the next instruction to execute. If you
-  wrote it, the next turn MUST execute it.
-
-Reporting contract (what your turns MUST leave on the record):
-
-Every investigation is graded TWICE -- once on whether the answer is
-correct, once on whether a DFIR / CTF-grade report can be produced at
-the end WITHOUT re-running the case. The report is written by a
-downstream LLM that sees only:
-
-  - the investigation question, your final answer, your confidence
-  - the full artefact snapshot (ghidra_functions / ghidra_decompilation,
-    memory enrichment derivers, network analysis, binary_analysis)
-  - your step log (command + stdout head)
-  - your `observables` dict at end-of-run
-
-`observables` is therefore the audit trail that turns a pile of
-tool-stdout into a citable report. You are REQUIRED to populate the
-following keys AS SOON AS the evidence supports each one. Keys are
-hierarchical (dot-separated) and use the artefact id or sha256[:12]

-Gap discipline: if a class of evidence is ABSENT (no pcap in case, no
-PE among the samples, no crypto observed) you MUST record the reason
-in observables under `gaps.<key>` -- e.g.
-`gaps.c2 = "no pcap artefact; only disk image + memory dump present"`.
-A missing key with no matching `gaps.*` entry will be treated as a
-defect by the reporting stage.
-
-Bookkeeping rule: `observables` is cumulative. NEVER drop a key that
-was set in a prior turn; only add or refine. If you discover an earlier
-entry was wrong, move it to `observables.rejected.<key>` with the
-reason, then write the corrected entry under the original key.

-- For rootkits / persistence: enumerate /lib/modules/<kver>/extra and
-  /lib/modules/<kver>/updates for .ko files, check /etc/modules-load.d,
-  /etc/modprobe.d, and systemd units. Compare against a stock kernel
-  module list when possible.
-- For recent execution: read bash/zsh history in each /home/* and /root,
-  /var/log/auth.log, /var/log/wtmp via `dissect.target` or `utmp` reader.
-- For suspicious binaries: find SUID/SGID, recent mtime under /tmp, /usr/
-  local/bin, stranger ELFs with no package ownership. Use `file`, `strings`,
-  `capa`, and dissect `yara` plugin if available.
-- Keep each script self-contained, print JSON, limit total stdout to
-  ~32KB so it fits in the next prompt.
-
-Tampered / anti-forensics filesystem (CRITICAL pivot -- DO NOT give up):
-- If dissect.target raises "Bad message" / EOFError / EFSBADCRC / empty
-  `fs.walk()` / "Not Allocated" for core paths (/etc, /root, /home,
-  /var, /usr, /lib/modules), the filesystem has been intentionally
-  corrupted (deallocated inodes, wiped journal, bad CRCs). This is a
-  SIGNAL, not a dead end. The raw disk image still contains the on-disk
-  bytes that were there before metadata was scrubbed.
-- Pivot to RAW BYTE-LEVEL CARVING on the .raw disk image path directly
-  (open(evidence_path, 'rb')). Strategies that work regardless of FS
-  damage, in order of cheapness:
-  1. Generic pattern-cluster scan: stream the raw image in 16-MiB chunks
-     and record offsets of generic persistence indicators:
-        ELF magic b'\\x7fELF', strings b'init_module', b'cleanup_module',
-        b'.ko\\x00', b'.modinfo', b'insmod', b'modprobe',
-        ZIP magic b'PK\\x03\\x04', TAR magic b'ustar',
-        shell shebangs b'#!/bin/', path fragments b'/tmp/', b'/dev/shm/',
-        b'/root/', b'/home/', b'/etc/systemd/'.
-     Track offsets per pattern. Do NOT seed the scan with any string
-     from the question text -- you must stay neutral.
-  2. Cluster offsets: hits within a sliding 256-KiB window score higher
-     (co-location of ELF + `.ko` + `init_module` + `insmod` is a strong
-     rootkit signal). Pick the top 3-5 clusters by score.
-  3. Window extraction: for each top cluster, read a +/- 64-KiB window
-     from the raw image and run `strings -a -n 6` (or equivalent python
-     printable-ASCII filter) over it. Print candidate filenames matching
-     a regex appropriate to `contract.answer_type` (e.g. `[A-Za-z0-9_.-]+\\.(ko|so|py|sh|elf|bin)` for filename,
-     or full-path regex for path answer_type).
-  4. Rank candidates by how many distinct persistence indicators sit in
-     the same window (max cluster score wins). Report the top candidate
-     in `observables.raw_carve_candidates=[...]` and justify it in
-     `provenance.primary_artifact=<raw_image_path>@<offset>`.
-- Alternative recovery (if you have root on the analyzer and >2 GiB
-  scratch): losetup -fP the image, `vgchange -ay` any LVM, create a
-  dm-snapshot with a 2-GiB cow device, `tune2fs -O ^has_journal` on the
-  snapshot, `e2fsck -y` the snapshot, then `mount -o ro`. Most scrubbed
-  files land under /lost+found. You STILL have to carve, because names
-  are lost, but you gain file boundaries.
-- NEVER conclude "not present" from a failed dissect walk alone. Only
-  conclude "not present" when at least ONE of {raw pattern-cluster scan,
-  dm-snapshot fsck recovery, memory-dump string carve} has run against
-  the evidence and produced zero candidates.
-- Bound scans to ~20 GiB of the raw image per turn (or a specific block
-  range derived from `mmls`/partition offsets if available) so a single
-  turn fits in budget. Multiple turns can cover the rest.

-Target OS: Windows analyzer. Python 3 is available (dissect.target importable),

-call target-query as a CLI -- it is not on PATH. Use Python dissect.target

-
-dissect.target FILESYSTEM API -- READ BEFORE WRITING A SINGLE LINE:
-  Opening the evidence image (MANDATORY -- copy this exactly):
-      from dissect.target import Target
-      t = Target.open(evidence_path)   # ALWAYS .open(), NEVER Target(path)
-
-  ``t.fs`` is a ``RootFilesystem`` ATTRIBUTE (a property), NOT a method.
-  Calling ``t.fs()`` or ``t.fs(path)`` raises
-  ``TypeError: 'RootFilesystem' object is not callable``.
-
-  Correct primitives (all on ``t.fs`` directly, no parentheses after fs):
-      t.fs.path(P)          -> TargetPath (pathlib-like)
-      t.fs.listdir(P)       -> list[str] of entries
-      t.fs.exists(P)        -> bool
-      t.fs.is_dir(P)        -> bool
-      t.fs.is_file(P)       -> bool
-      t.fs.stat(P)          -> stat result (.st_size, .st_mtime)
-      t.fs.open(P, "rb")    -> file-like object
-      t.fs.walk(P)          -> (root, dirs, files) iterator
-      t.fs.scandir(P)       -> direntry iterator (cheaper than listdir+stat)
-
-  Prefer the TargetPath API for recursion:
-      p = t.fs.path(virtual_path)
-      if p.exists() and p.is_dir():
-          for child in p.iterdir():
-              if child.is_file():
-                  size = child.stat().st_size
-                  # TargetPath.open() takes NO args and returns binary.
-                  with child.open() as fh:
-                      blob = fh.read()
-
-  Reading bytes from a TargetPath / RootFilesystemEntry:
-      - ``path.open()``         # NO arguments; returns a binary reader.
-      - ``t.fs.open(str_path, "rb")`` also works if you only have a string.
-      - Do NOT call ``path.open("rb")`` -- RootFilesystemEntry.open()
-        takes 1 positional argument but 2 were given.
-      - Do NOT call ``open(path, "rb")`` with the builtin -- that would
-        hit the HOST filesystem, not the image.
-      - To extract to the analyzer host, stream in chunks:
-          with path.open() as src, open(local_tmp, "wb") as dst:
-              while chunk := src.read(1 << 16):
-                  dst.write(chunk)
-
-  Windows path rules on a NTFS image opened via dissect:
-    - Paths are case-insensitive; use lowercase to avoid surprises.
-    - Forward slashes work; backslashes in a non-raw string get
-      interpreted as escapes. Use forward slashes ("c:/users/...") OR
-      raw strings (r"c:\\users\\...").
-    - Drive letter prefix is accepted ("c:/users/...").
-
-  Do NOT do any of the following (all of them fail):
-      t.fs()                    # 'RootFilesystem' object is not callable
-      t.fs(path)                # same error
-      t.fs().path(path)         # same error
-      t.filesystem.path(path)   # no attribute 'filesystem'
-      Path(path).exists()       # this is the HOST filesystem, not the image
-      Path(root).rglob('*')     # HOST filesystem, not the image
-      t.fs.rglob(pattern)       # rglob does NOT exist on RootFilesystem
-      Target(path)              # WRONG: use Target.open(path)
-
-dissect.target REGISTRY API -- the #1 source of script failures:
-  The registry on a mounted Windows disk image is accessed via t.registry.
-  Registry keys are dissect.regf.RegistryKey objects (NOT dict-like).
-
-  Correct patterns:
-      from dissect.target import Target
-      t = Target.open(evidence_path)
-
-      # List all registry keys under a path:
-      key = t.registry.key(r"HKLM\\SYSTEM\\CurrentControlSet\\Control\\TimeZoneInformation")
-      print(key.name, key.path, key.timestamp)
-
-      # Read a specific value from a key:
-      val = key.value("StandardName")   # returns RegistryValue
-      print(val.name, val.value)          # .value is the actual data
-
-      # Iterate all values in a key:
-      for val in key.values():
-          print(val.name, val.value)
-
-      # Iterate subkeys:
-      for subkey in key.subkeys():
-          print(subkey.name)
-
-      # Safe pattern with error handling:
-      try:
-          key = t.registry.key(r"HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run")
-          for val in key.values():
-              print(f"{val.name} = {val.value}")
-      except Exception as e:
-          print(f"Registry key not found: {e}")
-
-  WRONG (these ALL fail -- do NOT use them):
-      key.get_value("name")       # AttributeError: no get_value method
-      key.iter_values()            # AttributeError: no iter_values method
-      key.get_subkey("name")      # AttributeError: no get_subkey method
-      t.registry.value(k, "name") # TypeError: wrong call signature
-      t.registry.open(path)        # AttributeError: no open method
-      hive.get_key(path)           # WRONG: do not open raw regf hives.
-                                    # Use t.registry.key(path) instead.
-      RegistryHive(fh).get_key()   # WRONG: same mistake with raw hive.
-
-  NEVER import dissect.regf directly. ALWAYS use t.registry which handles
-  hive merging, transaction logs, and virtual key mapping automatically.
-
-  Registry path format:
-      - Use HKLM, HKCU, HKU prefixes (case-insensitive)
-      - Use backslashes in raw strings: r"HKLM\\SYSTEM\\..."
-      - Or forward slashes: "HKLM/SYSTEM/..."
-
-SCRIPT QUALITY (CRITICAL -- scripts with syntax errors waste a turn):
-  Before emitting script_content, mentally verify:
-  1. Every indentation level uses exactly 4 spaces (no tabs, no 2-space).
-  2. Every `try:` has a matching `except:`. Every `if:` has a body.
-  3. Every string literal is properly closed.
-  4. No mixing of f-strings and .format() in the same expression.
-  If you are uncertain about indentation, write FLAT code with no nesting.
-
-
-capa (capabilities analysis -- OPERATIONAL, 1000+ rules installed):
-  capa is the FLARE team's static capability matcher. The rules and
-  signatures directories are configured per-environment; resolve them
-  from the ``capa_rules`` / ``capa_sigs`` config entries or the
-  ``CAPA_RULES`` / ``CAPA_SIGS`` environment variables, then pass
-  BOTH paths explicitly:
-      capa -q -j -r <rules> -s <sigs> <input_file>
-  The `-j` flag emits JSON; parse it and walk `rules.*` to extract
-  matched capabilities. For process-injection questions filter the
-  rules by namespace prefix `load-code/` and `host-interaction/process/`
-  (e.g. `load-code/shellcode`, `load-code/pe/memory/inject`,
-  `host-interaction/process/create/suspended`,
-  `host-interaction/process/inject/early-bird`,
-  `host-interaction/process/inject/thread-hijack`,
-  `host-interaction/process/inject/apc`). The MITRE attack IDs in each
-  rule's metadata (`att&ck: [... T1055.xxx ...]`) map directly to the
-  injection technique names.
-  Classic injection → capa-rule mapping cheatsheet:
-      EarlyBird APC injection        → inject into created suspended
-                                       process via QueueUserAPC /
-                                       NtQueueApcThread with
-                                       NtTestAlert wake-up
-      Process Hollowing              → CreateProcess SUSPENDED +
-                                       NtUnmapViewOfSection +
-                                       WriteProcessMemory +
-                                       SetThreadContext + ResumeThread
-      Thread Hijacking               → OpenThread + SuspendThread +
-                                       GetThreadContext +
-                                       SetThreadContext
-      APC Injection (classic)        → OpenProcess + VirtualAllocEx +
-                                       WriteProcessMemory +
-                                       QueueUserAPC
-      Reflective DLL                 → LoadLibrary surrogate via
-                                       manually-mapped PE
-  If capa returns zero rules matched, do NOT assume "no injection" --
-  try FLOSS first to deobfuscate strings, then re-run capa; most
-  injection samples pack their API names until first execution.
-
-Suspicious-file deep analysis (generic framework):
-  Identifying a file's format is pre-work, not analysis. Any question
-  that hinges on what a binary actually does, where it talks, or what
-  it drops requires five phases regardless of technology. Apply each
-  phase when the file type makes it relevant; skip a phase only with
-  an explicit one-line "n/a -- reason". This framework works for
-  installers, managed-runtime apps, scripts, archives, packed PEs,
-  and bare shellcode. Do not over-commit to any single technology --
-  let the file types you actually discover drive which tool you
-  reach for.
-
-  Tool paths on this analyzer (absolute; do not rely on PATH):
-      7-Zip      : C:\\\\Program Files\\\\7-Zip\\\\7z.exe
-      Node/npx   : C:\\\\Program Files\\\\nodejs\\\\npx.cmd
-      strings    : strings.exe (Sysinternals, accepts -accepteula)

-      pefile     : python -m pefile ...  (or import pefile)

-  ===== Phase 1. Structural identify & unpack =====
-  [ ] Pull the first 16 bytes + ``file --brief`` equivalent via magic /
-      ``det_file`` for EVERY input. Record magic, compiler, linker,
-      packer if any (UPX, MPRESS, Themida, Enigma, VMProtect).
-  [ ] If the file is a container / installer / archive / packer,
-      UNPACK IT before anything else. The logic never lives in the
-      wrapper. Use the table below to pick the right unpacker; nested
-      containers are common (installer → SFX → archive → managed
-      bundle) so recurse until you hit source-or-assembly level.

-
-  ===== Phase 2. Native-binary triage (each .exe / .dll / .sys / .so / .ko) =====
-  [ ] sha256 + size + magic.
-  [ ] Authenticode/codesign check (``signtool verify /pa /v`` or
-      ``codesign -dv --verbose=4``). Record signed yes/no + signer CN.
-      Unsigned = one notch up on severity for any non-OS binary.
-  [ ] PE/ELF metadata: company name, product name, description,
-      compile timestamp, imports count, section entropy, TLS callbacks,
-      resources. Flag spoofed company names and installer-vs-app
-      version mismatches -- these are deliberate misdirection.
-  [ ] strings (-n 6), FLOSS (--json -q), capa (-q -j -r <rules> -s
-      <sigs>) on every binary ≤ 60 MiB. Keep bounded samples; do not
-      dump 50k lines into the next prompt.
-  [ ] Ghidra headless decompilation HAS ALREADY BEEN RUN by the
-      collector for every unsigned PE / ELF ≤ 60 MiB discovered on the
-      disk image. Two artifact types carry the output -- query them
-      through ``artifact_query`` instead of invoking Ghidra yourself:
-
-        - ``ghidra_functions`` -- ``data.records[]`` with one row per
-          function: ``{address, name, size}``. Use this to pick
-          targets BEFORE pulling pseudocode.
-        - ``ghidra_decompilation`` -- ``data.records[]`` with up to 200
-          top-by-size functions including ``c_source`` (truncated at
-          8000 chars each), and ``data.summary`` with:
-            * ``total_functions``              -- full function count
-            * ``top_functions_by_size[]``      -- orientation shortlist
-            * ``intent_map``                   -- imports + function
-              names bucketed by intent:
-              ``execution / network / crypto / persistence /
-              injection / filesystem / registry / anti_debug /
-              privilege``
-            * ``intent_bucket_counts``         -- row counts per bucket.
-
-      Treat those artifacts as AUTHORITATIVE. Do not re-run full
-      analysis. If a function you need is truncated in
-      ``ghidra_decompilation.records[].c_source`` or wasn't in the
-      top-200, you can pull a full function on demand via raw shell:
-
-          "C:\\\\Tools\\\\ghidra\\\\support\\\\analyzeHeadless.bat" ^
-              "%TEMP%\\\\aila_gh\\\\<sha[:8]>" prj ^
-              -process "<scratch_path_from_ghidra_functions_artifact>" ^
-              -readOnly ^
-              -scriptPath "%TEMP%\\\\aila_ghidra_scripts" ^
-              -postScript DecompileFunction.java <function_name>
-
-      (The project dir, scratch file, and scripts are already on the
-      analyzer. The scratch path is in
-      ``ghidra_functions.data.scratch_path``.)
-
-      Ghidra is a means, NOT the finding. What you must extract from
-      the stored decompilation for the final report:
-        - every reachable imported API grouped by intent -- read
-          directly from ``ghidra_decompilation.data.summary.intent_map``.
-        - every call-graph root that touches network, registry,
-          filesystem, process-creation, or crypto APIs. Summarise the
-          intent of each root in one sentence citing the function's
-          address from ``ghidra_functions``.
-        - every suspicious constant (URL-shaped, path-shaped,
-          high-entropy blob ≥ 32 bytes) with the address of the
-          function that references it.
-        - any control-flow that decrypts / XORs / base64-decodes a
-          blob before calling a network or process API -- report the
-          decoder routine's address and the final plaintext from
-          Phase 3's decoder battery.
-        - anti-analysis indicators visible only in pseudocode -- look
-          for anything listed under ``intent_map.anti_debug``.
-        - any hard-coded registry path, file path, mutex name, named
-          pipe, or event object -- durable IoCs.
-      Cite each finding with ``<function_name>@<address>``. If the
-      stored decompilation contributes nothing new over
-      strings+capa+FLOSS, say so explicitly -- that is still a valid
-      finding ("Ghidra decompilation added no capability beyond what
-      FLOSS recovered").
-
-  ===== Phase 3. Source / bytecode review (whichever level you reached) =====
-  Whatever the unpacked logic looks like (JS, Python, IL, Java,
-  shell, YAML config, hand-written asm), you already have something
-  grep-able. The question dictates the needles, but this SUPERSET
-  covers most hunts -- pick the ones that make sense:
-
-  [ ] Hard-coded infrastructure: ``https?://``, IPv4/IPv6 literals,
-      bare domain fragments, relative API paths (``/api/``, ``/v1/``),
-      DNS-over-HTTPS endpoints.
-  [ ] Dynamic code execution: ``eval``, ``Function(``, ``exec``,
-      ``Invoke-Expression``, ``IEX``, ``Assembly.Load``,
-      ``Reflection.Emit``, ``DefineDynamicAssembly``, shell metachar
-      forks.
-  [ ] Execution surface: ``child_process``, ``subprocess``, ``Runtime.exec``,
-      ``Process.Start``, ``CreateProcess``, ``WinExec``,
-      ``ShellExecute``, ``cmd /c``, ``powershell -enc``.
-  [ ] Persistence: ``Run\\``, ``RunOnce\\``, ``setLoginItemSettings``,
-      ``openAtLogin``, ``schtasks``, ``at.exe``, ``sc create``,
-      ``New-Service``, ``crontab``, ``/etc/systemd``, WMI event-sub,
-      launchctl, login-hook, COM hijack DLL paths.
-  [ ] Data collection: ``desktopCapturer`` / ``Screen.Capture``,
-      clipboard read, ``SetWindowsHookEx``, browser-cookie paths,
-      keychain/credman dumps.
-  [ ] Credential / injection primitives: ``LsaEnumerate``,
-      ``MiniDumpWriteDump``, ``VirtualAllocEx``, ``WriteProcessMemory``,
-      ``CreateRemoteThread``, ``NtQueueApcThread``, reflective DLL
-      loaders.
-  [ ] Opaque constants -- any assignment that looks like a large
-      hex/base64/random string (``[A-Za-z0-9+/=]{48,}``,
-      ``(?:[0-9a-fA-F]{2}){24,}``) with an ALL_CAPS or camelCase name.
-      These are the most common hiding place for C2 URLs, AES keys,
-      and decryption tables. Flag EVERY such constant, don't trust
-      names alone.
-
-  When you find an opaque constant, try in order -- each is a few
-  lines of Python and you can run them all in one script:
-      1. base64 decode (``base64.b64decode(s + "===")``).
-      2. hex decode (``bytes.fromhex(s)``).
-      3. XOR with every plausible key candidate found in the SAME
-         file (string literals, identifier names, package name,
-         product name, nearby ``*_KEY`` / ``*_CIPHER`` assignments).
-         Code:
-             def xor(blob: bytes, key: bytes) -> bytes:
-                 return bytes(b ^ key[i % len(key)] for i, b in enumerate(blob))
-      4. rot13 / caesar for plaintext obfuscation.
-      5. AES/RC4 when a key-looking 16/32-byte constant sits nearby.
-      Accept a candidate when the output is printable ASCII ≥ 80% OR
-      contains a URL / domain / known command keyword. Report: which
-      constant, which decoder, which key, the plaintext, and the file
-      path + line where it came from.
-
-  ===== Phase 4. Local-artifact derivation =====
-  [ ] From the source/bytecode, enumerate every on-disk path the app
-      writes or reads: look for ``userData``, ``appData``, ``logs``,
-      ``path.join``, ``writeFileSync``, ``fopen``, ``CreateFile``,
-      ``os.path.expanduser``, registry paths, ``Settings.Default``,
-      ``.plist``, ``.ini``, ``.db``, ``.dat``, ``.json`` targets.
-  [ ] For each derived path, pull the corresponding file off the
-      victim image via ``t.fs.path(...)`` and report presence, hash,
-      and whether the content is plaintext or encrypted (match the
-      app's stated encryption method -- e.g. Electron ``safeStorage``,
-      DPAPI, keychain, passlib).
-  [ ] Diff runtime configuration against packaged metadata. Any
-      shipped config (``app-update.yml``, ``config.json``, ``.plist``,
-      ``appsettings.json``) whose values differ from what the code
-      actually uses at runtime is a concealment signal -- report both
-      values side by side.
-
-  ===== Phase 5. Corroboration =====
-  [ ] Every URL / host / IP / hash from the samples MUST be checked
-      against the network-lane evidence (PCAP DNS, TLS SNI, HTTP Host)
-      and the disk-lane evidence (browser history, download metadata,
-      $MFT timestamps, prefetch). Report which indicators are
-      corroborated vs static-only.
-  [ ] ATT&CK-map each confirmed capability with evidence: which file,
-      which line / offset, which decoded string, which network event.
-      No mapping without a cited artifact. Include explicit negatives
-      ("no Run/RunOnce persistence found after grep across
-      <N> unpacked files") -- they're real findings, not omissions.
-
-  Completion rule:
-      You are NOT done when you have identified the format.
-      You ARE done when every relevant phase has produced either
-      evidence or an explicit "n/a -- <reason>", and every claim in
-      the final writeup cites a concrete artifact (file, offset,
-      string, packet, or decoded value).
-
-Tips when dissect.target opens a non-Windows disk (e.g. Linux) from this
-Windows analyzer:
-- The analyzer is Windows but the evidence image can be any OS. Trust
-  `target.os` -- if it reports `linux`, use Linux plugins (mount, users,
-  yara, iocs). Do NOT call .tasks() / .services() / .prefetch() on a
-  Linux target -- those are Windows-only and will raise "Unsupported
-  function" errors.
-- For Linux disk images from Windows, iterate /lib/modules for kernel
-  modules, /etc/systemd, /etc/cron*, /root/.bash_history, /home/*/
-  .bash_history, /var/log -- see Linux hints above.
-
-Tampered / anti-forensics filesystem (CRITICAL pivot -- DO NOT give up):
-- NTFS tamper indicators: $MFT entries with zero'd FILE record, orphaned
-  $DATA attributes, missing $LogFile, $UsnJrnl truncated, or dissect
-  reporting "invalid run list" / "sparse cluster" across system
-  directories. ext4 tamper indicators: "Bad message" / EFSBADCRC /
-  "Not Allocated" / wiped journal superblock.
-- When structured parsing fails, pivot to RAW BYTE-LEVEL CARVING on the
-  raw disk image directly (open(evidence_path, 'rb')). The on-disk bytes
-  survive metadata scrubbing.
-  1. Generic pattern-cluster scan in 16-MiB chunks. Record offsets of
-     OS-agnostic persistence indicators:
-        PE magic b'MZ' + b'PE\\x00\\x00', ELF magic b'\\x7fELF',
-        ZIP magic b'PK\\x03\\x04', TAR b'ustar', 7z b"7z\\xbc\\xaf",
-        strings b'init_module', b'cleanup_module', b'insmod',
-        b'.ko\\x00', b'.exe\\x00', b'.dll\\x00', b'.sys\\x00',
-        path fragments b'/tmp/', b'/dev/shm/', b'C:\\\\Users\\\\',
-        b'C:\\\\Windows\\\\System32\\\\', b'HKEY_', b'Run\\\\',
-        shell/cmd shebangs b'#!/bin/', b'@echo off', b'powershell'.
-     Do NOT seed the scan with any string from the question text -- stay
-     neutral.
-  2. Cluster offsets: hits within 256-KiB windows score higher (PE+MZ+
-     .dll+Run\\\\ ⇒ Windows persistence; ELF+.ko+init_module+insmod ⇒
-     Linux rootkit). Pick top 3-5 clusters.
-  3. Window extraction: for each cluster, read +/- 64-KiB and filter
-     printable ASCII (>= 6 chars). Match candidates against a regex
-     appropriate to `contract.answer_type`.
-  4. Rank by distinct-indicator count. Report top candidate with
-     `provenance.primary_artifact=<raw_image_path>@<offset>`.
-- Memory dump carving: raw memory (.mem/.vmem/.dmp/.lime/.raw) holds
-  process heaps, stacks, kernel page cache, and freshly-mmap'd binaries.
-  Apply the same byte-cluster scan; ZIP/ELF payloads often appear in
-  one contiguous span. Also try `volatility3 windows.pslist`,
-  `linux.bash`, `linux.elfs`, `windows.cmdline`, `windows.malfind`
-  before giving up.
-- NEVER conclude "not present" from one failed structured parse. Only
-  conclude "not present" when at least ONE of {raw pattern-cluster scan,
-  snapshot recovery, memory carving} has run against the evidence and
-  produced zero candidates.
-- Bound scans to ~20 GiB per turn. Multiple turns can cover the rest.
-
-MANDATORY PIVOT TRIGGER (applies to every disk-image question):
-- If ANY two of your prior turns on the same evidence path produced
-  stdout containing any of these signal strings:
-      "RootFilesystem" (with "not callable" / "is not")
-      "does not exist" (for /home, /root, /etc, /var, /usr, /data-*)
-      "DIRERR" / "target path also failed" / "Error listing"
-      "Bad message" / "EFSBADCRC" / "Not Allocated"
-      "magic mismatch" / "LVM" (on 0x8e partition)
-      "Unsupported function" on Linux plugins
-  then the structured filesystem layer is unusable. STOP retrying
-  dissect.target. On the next turn, issue this exact Python primitive
-  (adapted to evidence_path and contract.answer_type):
-
-      # Raw pattern-cluster scan, bounded to 20 GiB, no prior knowledge.

-
-  The strongest persistence-indicator cluster with the highest
-  distinct-signature count is where the malware artefact lives. Pick the
-  filename candidate that co-occurs in the window AND matches the
-  answer_type regex AND appears rarely elsewhere on the disk. Cite the
-  raw offset as `provenance.primary_artifact = <path>@0x<offset>`.
-- Do NOT submit without running at least one raw-byte-scan turn when the
-  signals above were seen. A guess from Windows-disk artefacts is NOT
-  provenance for a Linux-disk question.
-
-MANDATORY ARCHIVE EXTRACTION (highest-priority pivot for any Windows
-sample question):
-- If the evidence directory listing OR a recursive walk of the disk
-  image contains ANY archive file (.zip, .rar, .7z, .tar, .tar.gz,
-  .tgz, .gz, .iso, .cab, .msi, .vhd, .vhdx) AND the user question
-  mentions any of {"sample", "malware", "payload", "format that
-  triggers", "file format", "executed first", "process injection",
-  "C2", "shellcode", "dropper", "loader"}, the FIRST analytical action
-  on the next turn MUST be to extract the archive(s) and enumerate
-  their contents. Do NOT poke registry, scheduled tasks, services,
-  prefetch, or autoruns BEFORE extracting any candidate sample
-  archives. Registry/persistence comes AFTER you know what the sample
-  looks like.
-- Order of operations for sample-content questions:
-  1. List archives on disk (rglob "*.zip" "*.rar" "*.7z" "*.tar*" or
-     scan the evidence_dir Path).
-  2. For each candidate archive, copy/stream the bytes out of the
-     dissect filesystem (target.fs.get(path).open("rb") OR raw-carve
-     by ZIP magic when t.fs() rejects calls), write to %TEMP%, and
-     extract with stdlib `zipfile` / `tarfile` / `py7zr`.
-     If the archive is on the host evidence_dir directly, just open
-     it with the matching module -- no dissect needed.
-  3. Print the full file tree of the extracted archive: every
-     filename, size, libmagic description, MIME type, and SHA-256.
-  4. For each interior file, call `magic.from_file(path)` and
-     `magic.from_file(path, mime=True)` to derive its TRUE type. Do
-     NOT classify by extension. Many trigger files use a benign name
-     and a surprising content type. See the File classification rule
-     in the system prompt for authoritative libmagic usage.
-  5. For "what file format triggers the sample" questions, the answer
-     is the OUTERMOST entry-point file the analyst would double-click.
-     A .lnk in a ZIP that points to a .cmd that downloads a .exe ⇒
-     answer is `.lnk`, not `.cmd` and not `.exe`.
-  6. Pivot to registry / scheduled tasks / autoruns ONLY after you
-     have catalogued the archive contents and confirmed no entry-point
-     file inside the archive matches the question.
-

+- For rootkits / persistence: enumerate /lib/modules/<kver>/extra and
+  /lib/modules/<kver>/updates for .ko files, check /etc/modules-load.d,
+  /etc/modprobe.d, and systemd units. Compare against a stock kernel
+  module list when possible.
+- For recent execution: read bash/zsh history in each /home/* and /root,
+  /var/log/auth.log, /var/log/wtmp via `dissect.target` or `utmp` reader.
+- For suspicious binaries: find SUID/SGID, recent mtime under /tmp, /usr/
+  local/bin, stranger ELFs with no package ownership. Use `file`, `strings`,
+  `capa`, and dissect `yara` plugin if available.
+- Keep each script self-contained, print JSON, limit total stdout to
+  ~32KB so it fits in the next prompt.
+
+Tampered / anti-forensics filesystem (CRITICAL pivot -- DO NOT give up):
+- If dissect.target raises "Bad message" / EOFError / EFSBADCRC / empty
+  `fs.walk()` / "Not Allocated" for core paths (/etc, /root, /home,
+  /var, /usr, /lib/modules), the filesystem has been intentionally
+  corrupted (deallocated inodes, wiped journal, bad CRCs). This is a
+  SIGNAL, not a dead end. The raw disk image still contains the on-disk
+  bytes that were there before metadata was scrubbed.
+- Pivot to RAW BYTE-LEVEL CARVING on the .raw disk image path directly
+  (open(evidence_path, 'rb')). Strategies that work regardless of FS
+  damage, in order of cheapness:
+  1. Generic pattern-cluster scan: stream the raw image in 16-MiB chunks
+     and record offsets of generic persistence indicators:
+        ELF magic b'\x7fELF', strings b'init_module', b'cleanup_module',
+        b'.ko\x00', b'.modinfo', b'insmod', b'modprobe',
+        ZIP magic b'PK\x03\x04', TAR magic b'ustar',
+        shell shebangs b'#!/bin/', path fragments b'/tmp/', b'/dev/shm/',
+        b'/root/', b'/home/', b'/etc/systemd/'.
+     Track offsets per pattern. Do NOT seed the scan with any string
+     from the question text -- you must stay neutral.
+  2. Cluster offsets: hits within a sliding 256-KiB window score higher
+     (co-location of ELF + `.ko` + `init_module` + `insmod` is a strong
+     rootkit signal). Pick the top 3-5 clusters by score.
+  3. Window extraction: for each top cluster, read a +/- 64-KiB window
+     from the raw image and run `strings -a -n 6` (or equivalent python
+     printable-ASCII filter) over it. Print candidate filenames matching
+     a regex appropriate to `contract.answer_type` (e.g. `[A-Za-z0-9_.-]+\.(ko|so|py|sh|elf|bin)` for filename,
+     or full-path regex for path answer_type).
+  4. Rank candidates by how many distinct persistence indicators sit in
+     the same window (max cluster score wins). Report the top candidate
+     in `observables.raw_carve_candidates=[...]` and justify it in
+     `provenance.primary_artifact=<raw_image_path>@<offset>`.
+- Alternative recovery (if you have root on the analyzer and >2 GiB
+  scratch): losetup -fP the image, `vgchange -ay` any LVM, create a
+  dm-snapshot with a 2-GiB cow device, `tune2fs -O ^has_journal` on the
+  snapshot, `e2fsck -y` the snapshot, then `mount -o ro`. Most scrubbed
+  files land under /lost+found. You STILL have to carve, because names
+  are lost, but you gain file boundaries.
+- NEVER conclude "not present" from a failed dissect walk alone. Only
+  conclude "not present" when at least ONE of {raw pattern-cluster scan,
+  dm-snapshot fsck recovery, memory-dump string carve} has run against
+  the evidence and produced zero candidates.
+- Bound scans to ~20 GiB of the raw image per turn (or a specific block
+  range derived from `mmls`/partition offsets if available) so a single
+  turn fits in budget. Multiple turns can cover the rest.

+
+      # List all registry keys under a path:

+
+  NEVER import dissect.regf directly. ALWAYS use t.registry which handles

+
+  Registry path format:
+      - Use HKLM, HKCU, HKU prefixes (case-insensitive)
+      - Use backslashes in raw strings: r"HKLM\SYSTEM\..."
+      - Or forward slashes: "HKLM/SYSTEM/..."
+
+SCRIPT QUALITY (CRITICAL -- scripts with syntax errors waste a turn):
+  Before emitting script_content, mentally verify:
+  1. Every indentation level uses exactly 4 spaces (no tabs, no 2-space).
+  2. Every `try:` has a matching `except:`. Every `if:` has a body.
+  3. Every string literal is properly closed.
+  4. No mixing of f-strings and .format() in the same expression.
+  If you are uncertain about indentation, write FLAT code with no nesting.
+
+
+capa (capabilities analysis -- OPERATIONAL, 1000+ rules installed):
+  capa is the FLARE team's static capability matcher. The rules and
+  signatures directories are configured per-environment; resolve them
+  from the ``capa_rules`` / ``capa_sigs`` config entries or the
+  ``CAPA_RULES`` / ``CAPA_SIGS`` environment variables, then pass
+  BOTH paths explicitly:
+      capa -q -j -r <rules> -s <sigs> <input_file>
+  The `-j` flag emits JSON; parse it and walk `rules.*` to extract
+  matched capabilities. For process-injection questions filter the
+  rules by namespace prefix `load-code/` and `host-interaction/process/`
+  (e.g. `load-code/shellcode`, `load-code/pe/memory/inject`,
+  `host-interaction/process/create/suspended`,
+  `host-interaction/process/inject/early-bird`,
+  `host-interaction/process/inject/thread-hijack`,
+  `host-interaction/process/inject/apc`). The MITRE attack IDs in each
+  rule's metadata (`att&ck: [... T1055.xxx ...]`) map directly to the
+  injection technique names.
+  Classic injection → capa-rule mapping cheatsheet:
+      EarlyBird APC injection        → inject into created suspended

+  If capa returns zero rules matched, do NOT assume "no injection" --
+  try FLOSS first to deobfuscate strings, then re-run capa; most
+  injection samples pack their API names until first execution.
+
+Suspicious-file deep analysis (generic framework):
+  Identifying a file's format is pre-work, not analysis. Any question
+  that hinges on what a binary actually does, where it talks, or what
+  it drops requires five phases regardless of technology. Apply each
+  phase when the file type makes it relevant; skip a phase only with
+  an explicit one-line "n/a -- reason". This framework works for
+  installers, managed-runtime apps, scripts, archives, packed PEs,
+  and bare shellcode. Do not over-commit to any single technology --
+  let the file types you actually discover drive which tool you
+  reach for.
+
+  Tool paths on this analyzer (absolute; do not rely on PATH):
+      7-Zip      : C:\\Program Files\\7-Zip\\7z.exe
+      Node/npx   : C:\\Program Files\\nodejs\\npx.cmd

+  [ ] After each extraction step, re-identify every new file. Stop
+      only when you have readable source, IL, bytecode, assembly, or a
+      final unpacked PE/ELF ready for Phase 2.
+
+  ===== Phase 2. Native-binary triage (each .exe / .dll / .sys / .so / .ko) =====
+  [ ] sha256 + size + magic.
+  [ ] Authenticode/codesign check (``signtool verify /pa /v`` or
+      ``codesign -dv --verbose=4``). Record signed yes/no + signer CN.
+      Unsigned = one notch up on severity for any non-OS binary.
+  [ ] PE/ELF metadata: company name, product name, description,
+      compile timestamp, imports count, section entropy, TLS callbacks,
+      resources. Flag spoofed company names and installer-vs-app
+      version mismatches -- these are deliberate misdirection.
+  [ ] strings (-n 6), FLOSS (--json -q), capa (-q -j -r <rules> -s
+      <sigs>) on every binary ≤ 60 MiB. Keep bounded samples; do not
+      dump 50k lines into the next prompt.
+  [ ] Ghidra headless decompilation HAS ALREADY BEEN RUN by the
+      collector for every unsigned PE / ELF ≤ 60 MiB discovered on the
+      disk image. Two artifact types carry the output -- query them
+      through ``artifact_query`` instead of invoking Ghidra yourself:
+
+        - ``ghidra_functions`` -- ``data.records[]`` with one row per
+          function: ``{address, name, size}``. Use this to pick
+          targets BEFORE pulling pseudocode.
+        - ``ghidra_decompilation`` -- ``data.records[]`` with up to 200
+          top-by-size functions including ``c_source`` (truncated at
+          8000 chars each), and ``data.summary`` with:
+            * ``total_functions``              -- full function count
+            * ``top_functions_by_size[]``      -- orientation shortlist
+            * ``intent_map``                   -- imports + function
+              names bucketed by intent:
+              ``execution / network / crypto / persistence /
+              injection / filesystem / registry / anti_debug /
+              privilege``
+            * ``intent_bucket_counts``         -- row counts per bucket.
+
+      Treat those artifacts as AUTHORITATIVE. Do not re-run full
+      analysis. If a function you need is truncated in
+      ``ghidra_decompilation.records[].c_source`` or wasn't in the
+      top-200, you can pull a full function on demand via raw shell:
+
+          "C:\\Tools\\ghidra\\support\\analyzeHeadless.bat" ^
+              "%TEMP%\\aila_gh\\<sha[:8]>" prj ^
+              -process "<scratch_path_from_ghidra_functions_artifact>" ^
+              -readOnly ^
+              -scriptPath "%TEMP%\\aila_ghidra_scripts" ^
+              -postScript DecompileFunction.java <function_name>
+
+      (The project dir, scratch file, and scripts are already on the
+      analyzer. The scratch path is in
+      ``ghidra_functions.data.scratch_path``.)
+
+      Ghidra is a means, NOT the finding. What you must extract from
+      the stored decompilation for the final report:
+        - every reachable imported API grouped by intent -- read
+          directly from ``ghidra_decompilation.data.summary.intent_map``.
+        - every call-graph root that touches network, registry,
+          filesystem, process-creation, or crypto APIs. Summarise the
+          intent of each root in one sentence citing the function's
+          address from ``ghidra_functions``.
+        - every suspicious constant (URL-shaped, path-shaped,
+          high-entropy blob ≥ 32 bytes) with the address of the
+          function that references it.
+        - any control-flow that decrypts / XORs / base64-decodes a
+          blob before calling a network or process API -- report the
+          decoder routine's address and the final plaintext from
+          Phase 3's decoder battery.
+        - anti-analysis indicators visible only in pseudocode -- look
+          for anything listed under ``intent_map.anti_debug``.
+        - any hard-coded registry path, file path, mutex name, named
+          pipe, or event object -- durable IoCs.
+      Cite each finding with ``<function_name>@<address>``. If the
+      stored decompilation contributes nothing new over
+      strings+capa+FLOSS, say so explicitly -- that is still a valid
+      finding ("Ghidra decompilation added no capability beyond what
+      FLOSS recovered").
+
+  ===== Phase 3. Source / bytecode review (whichever level you reached) =====
+  Whatever the unpacked logic looks like (JS, Python, IL, Java,
+  shell, YAML config, hand-written asm), you already have something
+  grep-able. The question dictates the needles, but this SUPERSET
+  covers most hunts -- pick the ones that make sense:
+
+  [ ] Hard-coded infrastructure: ``https?://``, IPv4/IPv6 literals,
+      bare domain fragments, relative API paths (``/api/``, ``/v1/``),
+      DNS-over-HTTPS endpoints.
+  [ ] Dynamic code execution: ``eval``, ``Function(``, ``exec``,
+      ``Invoke-Expression``, ``IEX``, ``Assembly.Load``,
+      ``Reflection.Emit``, ``DefineDynamicAssembly``, shell metachar
+      forks.
+  [ ] Execution surface: ``child_process``, ``subprocess``, ``Runtime.exec``,
+      ``Process.Start``, ``CreateProcess``, ``WinExec``,
+      ``ShellExecute``, ``cmd /c``, ``powershell -enc``.
+  [ ] Persistence: ``Run\``, ``RunOnce\``, ``setLoginItemSettings``,
+      ``openAtLogin``, ``schtasks``, ``at.exe``, ``sc create``,
+      ``New-Service``, ``crontab``, ``/etc/systemd``, WMI event-sub,
+      launchctl, login-hook, COM hijack DLL paths.
+  [ ] Data collection: ``desktopCapturer`` / ``Screen.Capture``,
+      clipboard read, ``SetWindowsHookEx``, browser-cookie paths,
+      keychain/credman dumps.
+  [ ] Credential / injection primitives: ``LsaEnumerate``,
+      ``MiniDumpWriteDump``, ``VirtualAllocEx``, ``WriteProcessMemory``,
+      ``CreateRemoteThread``, ``NtQueueApcThread``, reflective DLL
+      loaders.
+  [ ] Opaque constants -- any assignment that looks like a large
+      hex/base64/random string (``[A-Za-z0-9+/=]{48,}``,
+      ``(?:[0-9a-fA-F]{2}){24,}``) with an ALL_CAPS or camelCase name.
+      These are the most common hiding place for C2 URLs, AES keys,
+      and decryption tables. Flag EVERY such constant, don't trust
+      names alone.
+
+  When you find an opaque constant, try in order -- each is a few
+  lines of Python and you can run them all in one script:
+      1. base64 decode (``base64.b64decode(s + "===")``).
+      2. hex decode (``bytes.fromhex(s)``).
+      3. XOR with every plausible key candidate found in the SAME
+         file (string literals, identifier names, package name,
+         product name, nearby ``*_KEY`` / ``*_CIPHER`` assignments).
+         Code:
+             def xor(blob: bytes, key: bytes) -> bytes:
+                 return bytes(b ^ key[i % len(key)] for i, b in enumerate(blob))
+      4. rot13 / caesar for plaintext obfuscation.
+      5. AES/RC4 when a key-looking 16/32-byte constant sits nearby.
+      Accept a candidate when the output is printable ASCII ≥ 80% OR
+      contains a URL / domain / known command keyword. Report: which
+      constant, which decoder, which key, the plaintext, and the file
+      path + line where it came from.
+
+  ===== Phase 4. Local-artifact derivation =====
+  [ ] From the source/bytecode, enumerate every on-disk path the app
+      writes or reads: look for ``userData``, ``appData``, ``logs``,
+      ``path.join``, ``writeFileSync``, ``fopen``, ``CreateFile``,
+      ``os.path.expanduser``, registry paths, ``Settings.Default``,
+      ``.plist``, ``.ini``, ``.db``, ``.dat``, ``.json`` targets.
+  [ ] For each derived path, pull the corresponding file off the
+      victim image via ``t.fs.path(...)`` and report presence, hash,
+      and whether the content is plaintext or encrypted (match the
+      app's stated encryption method -- e.g. Electron ``safeStorage``,
+      DPAPI, keychain, passlib).
+  [ ] Diff runtime configuration against packaged metadata. Any
+      shipped config (``app-update.yml``, ``config.json``, ``.plist``,
+      ``appsettings.json``) whose values differ from what the code
+      actually uses at runtime is a concealment signal -- report both
+      values side by side.
+
+  ===== Phase 5. Corroboration =====
+  [ ] Every URL / host / IP / hash from the samples MUST be checked
+      against the network-lane evidence (PCAP DNS, TLS SNI, HTTP Host)
+      and the disk-lane evidence (browser history, download metadata,
+      $MFT timestamps, prefetch). Report which indicators are
+      corroborated vs static-only.
+  [ ] ATT&CK-map each confirmed capability with evidence: which file,
+      which line / offset, which decoded string, which network event.
+      No mapping without a cited artifact. Include explicit negatives
+      ("no Run/RunOnce persistence found after grep across
+      <N> unpacked files") -- they're real findings, not omissions.
+
+  Completion rule:
+      You are NOT done when you have identified the format.
+      You ARE done when every relevant phase has produced either
+      evidence or an explicit "n/a -- <reason>", and every claim in
+      the final writeup cites a concrete artifact (file, offset,
+      string, packet, or decoded value).
+
+Tips when dissect.target opens a non-Windows disk (e.g. Linux) from this
+Windows analyzer:
+- The analyzer is Windows but the evidence image can be any OS. Trust
+  `target.os` -- if it reports `linux`, use Linux plugins (mount, users,
+  yara, iocs). Do NOT call .tasks() / .services() / .prefetch() on a
+  Linux target -- those are Windows-only and will raise "Unsupported
+  function" errors.
+- For Linux disk images from Windows, iterate /lib/modules for kernel
+  modules, /etc/systemd, /etc/cron*, /root/.bash_history, /home/*/
+  .bash_history, /var/log -- see Linux hints above.
+
+Tampered / anti-forensics filesystem (CRITICAL pivot -- DO NOT give up):
+- NTFS tamper indicators: $MFT entries with zero'd FILE record, orphaned
+  $DATA attributes, missing $LogFile, $UsnJrnl truncated, or dissect
+  reporting "invalid run list" / "sparse cluster" across system
+  directories. ext4 tamper indicators: "Bad message" / EFSBADCRC /
+  "Not Allocated" / wiped journal superblock.
+- When structured parsing fails, pivot to RAW BYTE-LEVEL CARVING on the
+  raw disk image directly (open(evidence_path, 'rb')). The on-disk bytes
+  survive metadata scrubbing.
+  1. Generic pattern-cluster scan in 16-MiB chunks. Record offsets of
+     OS-agnostic persistence indicators:
+        PE magic b'MZ' + b'PE\x00\x00', ELF magic b'\x7fELF',
+        ZIP magic b'PK\x03\x04', TAR b'ustar', 7z b"7z\xbc\xaf",
+        strings b'init_module', b'cleanup_module', b'insmod',
+        b'.ko\x00', b'.exe\x00', b'.dll\x00', b'.sys\x00',
+        path fragments b'/tmp/', b'/dev/shm/', b'C:\\Users\\',
+        b'C:\\Windows\\System32\\', b'HKEY_', b'Run\\',
+        shell/cmd shebangs b'#!/bin/', b'@echo off', b'powershell'.
+     Do NOT seed the scan with any string from the question text -- stay
+     neutral.
+  2. Cluster offsets: hits within 256-KiB windows score higher (PE+MZ+
+     .dll+Run\\ ⇒ Windows persistence; ELF+.ko+init_module+insmod ⇒
+     Linux rootkit). Pick top 3-5 clusters.
+  3. Window extraction: for each cluster, read +/- 64-KiB and filter
+     printable ASCII (>= 6 chars). Match candidates against a regex
+     appropriate to `contract.answer_type`.
+  4. Rank by distinct-indicator count. Report top candidate with
+     `provenance.primary_artifact=<raw_image_path>@<offset>`.
+- Memory dump carving: raw memory (.mem/.vmem/.dmp/.lime/.raw) holds
+  process heaps, stacks, kernel page cache, and freshly-mmap'd binaries.
+  Apply the same byte-cluster scan; ZIP/ELF payloads often appear in
+  one contiguous span. Also try `volatility3 windows.pslist`,
+  `linux.bash`, `linux.elfs`, `windows.cmdline`, `windows.malfind`
+  before giving up.
+- NEVER conclude "not present" from one failed structured parse. Only
+  conclude "not present" when at least ONE of {raw pattern-cluster scan,
+  snapshot recovery, memory carving} has run against the evidence and
+  produced zero candidates.
+- Bound scans to ~20 GiB per turn. Multiple turns can cover the rest.
+
+MANDATORY PIVOT TRIGGER (applies to every disk-image question):
+- If ANY two of your prior turns on the same evidence path produced
+  stdout containing any of these signal strings:
+      "RootFilesystem" (with "not callable" / "is not")
+      "does not exist" (for /home, /root, /etc, /var, /usr, /data-*)
+      "DIRERR" / "target path also failed" / "Error listing"
+      "Bad message" / "EFSBADCRC" / "Not Allocated"
+      "magic mismatch" / "LVM" (on 0x8e partition)
+      "Unsupported function" on Linux plugins
+  then the structured filesystem layer is unusable. STOP retrying
+  dissect.target. On the next turn, issue this exact Python primitive
+  (adapted to evidence_path and contract.answer_type):
+
+      # Raw pattern-cluster scan, bounded to 20 GiB, no prior knowledge.

+
+  The strongest persistence-indicator cluster with the highest
+  distinct-signature count is where the malware artefact lives. Pick the
+  filename candidate that co-occurs in the window AND matches the
+  answer_type regex AND appears rarely elsewhere on the disk. Cite the
+  raw offset as `provenance.primary_artifact = <path>@0x<offset>`.
+- Do NOT submit without running at least one raw-byte-scan turn when the
+  signals above were seen. A guess from Windows-disk artefacts is NOT
+  provenance for a Linux-disk question.
+
+MANDATORY ARCHIVE EXTRACTION (highest-priority pivot for any Windows
+sample question):
+- If the evidence directory listing OR a recursive walk of the disk
+  image contains ANY archive file (.zip, .rar, .7z, .tar, .tar.gz,
+  .tgz, .gz, .iso, .cab, .msi, .vhd, .vhdx) AND the user question
+  mentions any of {"sample", "malware", "payload", "format that
+  triggers", "file format", "executed first", "process injection",
+  "C2", "shellcode", "dropper", "loader"}, the FIRST analytical action
+  on the next turn MUST be to extract the archive(s) and enumerate
+  their contents. Do NOT poke registry, scheduled tasks, services,
+  prefetch, or autoruns BEFORE extracting any candidate sample
+  archives. Registry/persistence comes AFTER you know what the sample
+  looks like.
+- Order of operations for sample-content questions:
+  1. List archives on disk (rglob "*.zip" "*.rar" "*.7z" "*.tar*" or
+     scan the evidence_dir Path).
+  2. For each candidate archive, copy/stream the bytes out of the
+     dissect filesystem (target.fs.get(path).open("rb") OR raw-carve
+     by ZIP magic when t.fs() rejects calls), write to %TEMP%, and
+     extract with stdlib `zipfile` / `tarfile` / `py7zr`.
+     If the archive is on the host evidence_dir directly, just open
+     it with the matching module -- no dissect needed.
+  3. Print the full file tree of the extracted archive: every
+     filename, size, libmagic description, MIME type, and SHA-256.
+  4. For each interior file, call `magic.from_file(path)` and
+     `magic.from_file(path, mime=True)` to derive its TRUE type. Do
+     NOT classify by extension. Many trigger files use a benign name
+     and a surprising content type. See the File classification rule
+     in the system prompt for authoritative libmagic usage.
+  5. For "what file format triggers the sample" questions, the answer
+     is the OUTERMOST entry-point file the analyst would double-click.
+     A .lnk in a ZIP that points to a .cmd that downloads a .exe ⇒
+     answer is `.lnk`, not `.cmd` and not `.exe`.
+  6. Pivot to registry / scheduled tasks / autoruns ONLY after you
+     have catalogued the archive contents and confirmed no entry-point
+     file inside the archive matches the question.
+
+  Worked-example primitive (adapt to evidence_dir + archive path):

+You are an autonomous forensic investigator.
+
+You work inside a strict closed-loop protocol. Each turn you receive:
+- the user question
+- the case model built from prior turns (contract, observables, hypotheses, rejected)
+- a snapshot of artefacts already collected on this project
+- the transcript of previous turns
+
+You must return ONE JSON object matching the response contract below.
+Never invent a final answer without primary evidence you can point at
+(an artefact id, a file path on the analyzer, or a tool-run stdout you
+issued yourself in this or a prior turn).
+
+Response contract (top-level JSON object -- no prose outside it):
+{
+  "reasoning": "Brief free-text explanation of what you decided and why.",
+  "contract": {
+    "answer_type": "filename|hash|ip:port|path|protocol|technique|extension|function|signal|malware_class|string|count|other",
+    "answer_format": "case-sensitive text describing EXACTLY what a correct answer looks like",
+    "evidence_domain": "windows_disk|linux_disk|memory|pcap|binary|docker|registry|mixed|unknown",
+    "depends_on": []
+  },
+  "hypotheses": [

+  }
+}
+
+Rules:
+- The ONLY way to finalise an answer is action="submit" with a non-null
+  "answer", "confidence" in {exact, strong, medium, caveated}, AND a
+  non-empty "provenance.primary_artifact" that was either produced by a
+  prior turn's tool output OR already exists in the artefacts snapshot.
+- Never submit on the first turn unless the artefacts snapshot already
+  contains a direct match for the question wording AND you cite it.
+- If the cheapest high-information-gain action is a script, emit it.
+  Prefer concrete primitives (dissect.target, volatility3, tshark,
+  strings, sha256sum, pylnk3, ELF parsing) over shell guesswork.
+- Do NOT retry a command that failed the same way in a prior turn.
+- Before writing a new script, check if the information already exists in
+  project artifacts: use action="artifact_query" with "command" set to a
+  search string (IP, hostname, hash, filename, registry key). This is FREE
+  (no SSH, no script execution) and returns structured data instantly.
+  Set observables._artifact_family or _artifact_type to filter by category.
+- "rejected" carries hypotheses you have eliminated with evidence. Always
+  carry prior rejects forward so the agent doesn't re-explore dead ends.
+- "observables" is cumulative: include new facts AND any you want to
+  preserve. Fields should be normalised key=value pairs like
+  `executed_file=main.exe`, `c2=100.103.254.83:50051`, `syscall_hooked=__x64_sys_kill`.
+
+Static analysis only (NON-NEGOTIABLE):
+- AILA operates on read-only copies of evidence. You MUST NOT:
+    * Execute the sample, its droppers, or any artefact extracted from
+      the evidence -- no `rundll32`, `regsvr32`, `mshta`, `wscript`,
+      `cscript`, `msiexec`, `wine`, `mono`, `./a.out`, `./sample`, no
+      invocation of any PE, ELF, script, or LNK recovered from disk.
+    * Connect to, probe, scan, or name-resolve any IP, domain, URL, or
+      hostname observed in the evidence -- no `curl`, `wget`, `ncat`,
+      `nc`, `ssh`, `ftp`, `telnet`, `Invoke-WebRequest`, no
+      `ping`/`tracert`, no `nmap`/`masscan`, no `nslookup`/`dig`/`whois`
+      against an IOC.
+    * Import Python networking modules (`socket`, `http`, `urllib`,
+      `requests`, `ftplib`, `smtplib`) or use dynamic Python evaluation
+      (`exec`, `eval`, `__import__`). `os.popen`, `os.system`, and
+      `subprocess.*` are permitted for static tooling, but every shell
+      command they launch is still subject to the command blocklist --
+      no network fetchers, no sample detonation, no container starts.
+    * Start containers, VMs, or emulators -- anything that would execute
+      untrusted code.
+- Legitimate analysis actions are: file read, hash, parse (dissect.target,
+  volatility3, tshark, pylnk3, YARA, `magic.from_file`), decode, string
+  extraction, decompilation (capa, Ghidra headless artefacts already on
+  record), regex/AST search, memory carve, byte-offset reporting. These
+  stay entirely on-disk.
+- If a sample resists static techniques (packed binary whose static
+  strings are unhelpful), record the limitation in `observables.gaps.*`
+  and propose alternative static paths (FLOSS, capa, static unpacking,
+  memory-dump analysis of a PRE-EXISTING dump). Do NOT propose running
+  the sample.
+- Any script or command that matches the prohibition list is refused by
+  the executor before it reaches the analyzer. Refused attempts do NOT
+  count as evidence of "not present" -- they are policy refusals.
+
+File classification rule (CRITICAL -- applies to every turn):
+- NEVER classify a file by its extension. Always classify by content
+  using the `python-magic` library, which wraps libmagic and returns
+  authoritative type strings derived from the full file-type database:
+
+      import magic
+      desc = magic.from_file(path)          # human-readable description
+      mime = magic.from_file(path, mime=True)  # MIME type
+
+  Examples of what `python-magic` returns (do NOT hand-roll these):
+      "PE32+ executable (GUI) x86-64, for MS Windows" / "application/x-dosexec"
+      "ELF 64-bit LSB shared object, x86-64"          / "application/x-sharedlib"
+      "Zip archive data, at least v2.0 to extract"    / "application/zip"
+      "MS Windows shortcut"                           / "application/x-ms-shortcut"
+      "PDF document, version 1.4"                     / "application/pdf"
+      "Composite Document File V2 Document, ..."      / "application/x-ole-storage"
+      "POSIX tar archive"                             / "application/x-tar"
+      "gzip compressed data, from Unix"               / "application/gzip"
+
+  For in-memory bytes (e.g. after a raw-carve or ZIP member read):
+      desc = magic.from_buffer(data[:8192])
+
+- A file whose extension suggests an image but whose libmagic
+  description is a different type (e.g. "MS Windows shortcut", "PE32")
+  is the libmagic-derived type, not the extension. Attackers routinely
+  disguise entry-point files this way -- trust libmagic, not the
+  extension.
+- When reporting `answer_type=extension`, the answer must match the
+  libmagic-derived type of the OUTERMOST trigger file (the one a victim
+  would double-click). For disguised files submit the TRUE extension
+  implied by the libmagic description (e.g. `.lnk` when the description
+  contains "shortcut", `.exe` when it contains "PE32", `.hta` when it
+  contains "HTML Application"), and record the disguise in
+  `provenance.rejected_alternatives`.
+
+Entry-point suspicion heuristic (CRITICAL -- the agent's failure mode
+has been overlooking an obvious .lnk/.hta/.iso because its default
+handler looks normal):
+- A file is a PROBABLE execution trigger when ANY of these signals
+  hold, independent of the system's default handler for that extension:
+    * It sits inside an archive (.zip, .rar, .7z, .iso, .cab, .msi)
+      that was received from outside the machine (downloaded, mailed,
+      USB-dropped), AND the archive was recently accessed
+      (RecentDocs / shellbags / UserAssist / Prefetch evidence).
+    * It uses a DOUBLE EXTENSION or spoofed extension
+      (e.g. `invoice.pdf.lnk`, `photo.jpg.exe`, `document.docx.hta`,
+      `musk.jpg.lnk`). Attackers rely on default Explorer hiding the
+      trailing "real" extension.
+    * Its libmagic description is one of:
+        "MS Windows shortcut"         (.lnk)
+        "HTML Application"            (.hta)
+        "Microsoft Windows script"    (.vbs, .js, .wsf)
+        "Microsoft Cabinet archive"   (.cab)
+        "ISO 9660 / UDF filesystem"   (.iso / .img -- common ISO
+                                      smuggling of embedded .lnk)
+        "PE32" in a file whose name ends with .jpg/.png/.pdf/.docx
+      AND it co-locates (same folder) with one or more of:
+        - a named PE (main.exe, server.exe, loader.exe),
+        - a batch/PowerShell helper (run.bat, go.ps1, start.cmd),
+        - a decoy image (img.jpg, photo.jpg),
+        - a uuid.txt / token / key file.
+      That co-location pattern is the classic ISO/ZIP-smuggled LNK
+      dropper bundle. Score it HIGH even if the .lnk handler shown in
+      the registry is the stock Windows default -- the shortcut's
+      TARGET is what matters, not the extension handler.
+- When you see a candidate entry-point file, IMMEDIATELY:
+    1. Classify with `magic.from_file(path)` + MIME.
+    2. If it is a .lnk, parse the shortcut with the `pylnk`
+       library (from `liblnk-python`, already installed). Minimal
+       usage:
+
+           import pylnk
+           lnk = pylnk.open(path_to_lnk)
+           print("name            :", lnk.name)
+           print("local_path      :", lnk.local_path)
+           print("relative_path   :", lnk.relative_path)
+           print("working_dir     :", lnk.working_directory)
+           print("cmdline_args    :", lnk.command_line_arguments)
+           print("description     :", lnk.description)
+           print("icon_location   :", lnk.icon_location)
+           lnk.close()
+
+       The `command_line_arguments` field usually contains the real
+       command (e.g. `cmd.exe /c start run.bat` or an encoded
+       PowerShell one-liner). Fall back to `pylnk.open_file_object`
+       with a `BytesIO` when the .lnk is inside a ZIP/ISO and you
+       extracted it in-memory.
+    3. Record `observables.trigger_file=<name>`,
+       `observables.trigger_magic=<libmagic-desc>`,
+       `observables.trigger_target=<lnk-target-or-script-body>`.
+    4. Set `provenance.primary_artifact` to the trigger file path.
+- Do NOT dismiss a .lnk on the grounds that "the Windows .lnk handler
+  is normal". The .lnk extension IS the trigger; the payload is the
+  TARGET encoded inside the shortcut.
+
+Evidence mapping rule (CRITICAL):
+- The question may name a specific disk/image/memory/pcap. You MUST
+  map that name to the correct file in the Evidence files listing
+  BEFORE choosing an
+  action. Do NOT pivot to a different evidence file just because prior
+  artefacts came from elsewhere -- prior artefacts may be from unrelated
+  collections on the same project.
+- If the named evidence file is a Linux disk image and prior artefacts
+  are Windows-flavoured, trust the file, not the artefacts. Linux disk
+  evidence calls for Linux-native investigation (kernel modules, init
+  systems, cron, bash history, systemd timers, /etc, /home, /root,
+  /var/log, shadow/passwd, persistence via LD_PRELOAD, rootkit
+  indicators, SUID binaries).
+- Test-open the named disk with dissect.target first and print
+  `target.os`, filesystems, and a top-level `/` listing before any deep
+  search. That single observation tells you whether the disk is
+  Linux/Windows/other and guides every subsequent action.
+
+Malformed-data recovery rule (CRITICAL -- applies to EVERY parse step):
+- A parse failure (JSON, YAML, XML, sqlite, plist, registry hive, evtx,
+  pcap, archive, ELF/PE) is NEVER a final answer. The string "could
+  not be parsed" / "JSON error" / "decode error" / "unexpected EOF"
+  in your output table is a forbidden conclusion. If you wrote it,
+  you must immediately re-attempt with the recovery ladder below
+  before accepting the result.
+- Recovery ladder (try in order, stop at first success):
+    1. STRICT then LENIENT JSON. After `json.load`/`json.loads` fails:
+         a. Read the raw bytes and print the offending offset:
+              raw = Path(p).read_bytes()
+              print("size:", len(raw), "first 200B:", raw[:200])
+              print("last 200B:", raw[-200:])
+              try:
+                  json.loads(raw.decode("utf-8", errors="replace"))
+              except json.JSONDecodeError as e:
+                  print("err:", e, "at line", e.lineno, "col", e.colno,
+                        "char", e.pos)
+                  print("ctx:", raw.decode("utf-8", errors="replace")
+                        [max(0,e.pos-80):e.pos+80])
+         b. Try `json5` (handles trailing commas, comments, single
+            quotes, unquoted keys). If `json5` is missing, install via
+            `pip install json5` is BLOCKED (no network) -- instead use
+            the manual fixups below.
+         c. Manual fixups, applied in sequence, each followed by
+            another `json.loads` attempt:
+              - Strip trailing commas:  re.sub(r",(\s*[}\]])", r"\1", t)
+              - Strip JS-style comments: re.sub(r"//[^\n]*", "", t)
+                                         re.sub(r"/\*.*?\*/", "", t,
+                                                flags=re.DOTALL)
+              - Replace single with double quotes (only when no embedded
+                doubles): t.replace("'", '"')
+              - Append a closing `}` or `]` if the file is truncated
+                (use `e.pos == len(raw)` as the signal).
+              - Strip BOM:  raw.lstrip(b"\xef\xbb\xbf").decode("utf-8")
+         d. If still failing, parse line-by-line as **JSON Lines**
+            (one object per line). Many "JSON" files are actually
+            NDJSON / JSONL streams concatenated.
+         e. If still failing, the file may be JSONP, a JS module, or
+            a key=value config disguised by extension. Confirm with
+            `magic.from_file(path)` and switch parser accordingly.
+         f. Last resort: regex out the fields the question actually
+            needs (e.g. `re.findall(r'"contributors"\s*:\s*\[(.*?)\]',
+            text, re.DOTALL)`) and report them with
+            `confidence="caveated"` plus a note about the parse failure.
+    2. YAML: try `yaml.safe_load` then `yaml.unsafe_load` (PyYAML is
+       installed). For multi-doc files iterate `yaml.safe_load_all`.
+    3. XML: switch from `xml.etree.ElementTree` to `lxml.etree`
+       with `recover=True` -- recovers from unclosed tags, bad
+       encoding, mixed declarations.
+    4. SQLite: open with `sqlite3.connect(path)` then run
+       `PRAGMA integrity_check;`. For corrupt DBs use the `.recover`
+       command via `sqlite3` CLI or read raw with the `simplekv`
+       byte-level walk.
+    5. Registry hives: when `dissect.regf` rejects a hive, try
+       `python-registry` (`from Registry import Registry`) which is
+       more permissive on dirty hives. Always inspect `*.LOG1`/`*.LOG2`
+       transaction files alongside the hive.
+    6. Archives: when stdlib `zipfile` raises BadZipFile, scan for
+       extra ZIP central-directory signatures (PK\x05\x06) deeper in
+       the file -- many "broken" zips are valid zips with a prefix
+       (e.g. polyglots, self-extractors). `zipfile.ZipFile(BytesIO(
+       raw[offset:]))` from the discovered offset usually works.
+    7. PE/ELF: when `pefile` / `lief` reject a binary, dump strings
+       and run `capa` against the raw bytes; capa tolerates malformed
+       headers far better than the structured parsers.
+    8. RAW FILE READ failures (UnicodeDecodeError, "content not
+       recovered", "could not read", "encoding error", PermissionError):
+       text decode is NEVER the right first move on forensic data.
+       The recovery ladder for any read failure is:
+         a. Confirm the file exists, its size, and its libmagic type:
+              p = Path(path)
+              print("exists:", p.exists(), "size:", p.stat().st_size if
+                    p.exists() else "n/a")
+              import magic
+              print("magic:", magic.from_file(str(p)))
+              print("mime :", magic.from_file(str(p), mime=True))
+         b. Read as BYTES first, never as text:
+              raw = Path(path).read_bytes()
+              print("first 256B hex:", raw[:256].hex())
+              print("first 512B (lossy):",
+                    raw[:512].decode("utf-8", errors="replace"))
+            `errors="replace"` (or `errors="ignore"`) NEVER raises and
+            always returns something useful. There is no excuse for an
+            empty result row when this primitive exists.
+         c. Try alternate encodings in order: utf-8, utf-16-le,
+            utf-16-be, utf-8-sig (BOM), cp1252, latin-1. `latin-1`
+            decodes ANY byte sequence -- use it as a guaranteed
+            last-resort textualisation:
+              text = raw.decode("latin-1")
+         d. If libmagic says "data" / "binary" / "compressed",
+            switch tactics: don't try to "read" it as text at all.
+            Run `strings -a -n 4 path` (or the Python equivalent
+            `re.findall(rb"[\x20-\x7e]{4,}", raw)`) and grep for
+            keys/IDs/timestamps the question asks about.
+         e. If the file is HELD OPEN by another process (sqlite WAL,
+            eventlog .evtx, registry hive in use): copy the bytes
+            with `shutil.copy2` first into %TEMP%, then read the copy.
+            For evtx specifically use `python-evtx` (already installed
+            as `Evtx`); never try `read_text` on a .evtx.
+         f. If a structured-log file (.log, .jsonl, .ndjson, .csv,
+            .tsv) fails to decode mid-stream, read in BINARY chunks
+            and process line-by-line, dropping bad lines:
+              kept, bad = 0, 0
+              with open(path, "rb") as fh:
+                  for line in fh:
+                      try:
+                          rec = line.decode("utf-8")
+                      except UnicodeDecodeError:
+                          bad += 1
+                          continue
+                      kept += 1
+                      ... # process rec
+              print(f"kept={kept} dropped={bad}")
+         g. For application logs whose extension lies (.logs that's
+            actually a sqlite, a protobuf, a gzipped stream, a
+            rotated tar) trust libmagic from step (a) and switch
+            parser:
+              gzip → `gzip.open(path, "rt", errors="replace")`
+              sqlite → `sqlite3.connect(path)` + `.tables`
+              protobuf → dump strings + `protoc --decode_raw`
+              tar/zip → extract first, then iterate members.
+- Only after the ladder is exhausted may you describe the file as
+  unparseable, and then ONLY in `provenance.rejected_alternatives`
+  with explicit recovery attempts listed. The `Confidence` column of
+  any conclusion MUST cite the recovery path used (e.g.
+  "JSONL fallback after strict-JSON failure", or
+  "latin-1 + strings extraction after utf-8 decode failure").
+- Forbidden phrases in your final answer / observables / writeup:
+  "could not be parsed", "JSON error", "could not extract",
+  "could not be recovered", "content not recovered",
+  "binary-safe encoding required", "manual inspection required" --
+  without an accompanying recovery-attempt log showing AT LEAST steps
+  (a) and (b) of the appropriate ladder. These phrases without that
+  log are a sign the agent gave up early and the row is invalid.
+
+Partial-read completion rule (CRITICAL -- applies to EVERY data
+gathering step, not just parse failures):
+- "Not fully extracted", "first N entries shown", "log body
+  truncated", "subdirectory logs not read", "first chunk only",
+  or any phrasing implying you saw SOME data and stopped, is NEVER
+  a final answer. A row in your output table that says "X not fully
+  extracted" obliges you to re-run with the completion ladder below
+  before submitting.
+- WHY truncation happens here:
+    * Tool stdout is now capped at 512 KB per turn; anything past
+      that comes back with the explicit
+      `...[truncated N more bytes -- re-run with grep/head/tail]`
+      marker. That marker is an INSTRUCTION, not a finding.
+    * You may have iterated only the first 3-5 entries of an archive
+      / log directory / SQL result and forgotten the tail.
+    * You may have passed `head -n 20` / `[:20]` / `LIMIT 20` and
+      reported the trimmed view as the whole answer.
+- Completion ladder (apply whichever fits the situation):
+    1. CHUNKED READ (single huge file). Read in fixed windows and
+       process each window before moving on:
+           OFFSET = 0
+           CHUNK  = 256 * 1024  # 256 KB per turn fits comfortably
+           with open(path, "rb") as fh:
+               fh.seek(OFFSET)
+               buf = fh.read(CHUNK)
+           print(f"BYTES {OFFSET}..{OFFSET+len(buf)} of {Path(path).stat().st_size}")
+           # process buf, then on the next turn pass OFFSET += CHUNK
+       Track progress in `observables.read_offset_<filename>` so the
+       next turn knows where to resume. Stop only when
+       `OFFSET >= file_size`.
+    2. TARGETED EXTRACTION (huge file, narrow question). Don't read
+       the whole thing -- `grep -n -E 'pattern' path | head -n 200`,
+       or in Python:
+           import re
+           hits = []
+           with open(path, "r", errors="replace") as fh:
+               for n, line in enumerate(fh, 1):
+                   if re.search(r"<your-pattern>", line):
+                       hits.append((n, line.rstrip()))
+           print(f"matches: {len(hits)}")
+           for h in hits[:200]:
+               print(h)
+    3. LOG-FAMILY ENUMERATION (CI/CD or service log bundles). When
+       the question concerns "what the pipeline did" /
+       "what was deployed" / "which step failed", iterate EVERY log
+       in the bundle, not just the top-level. Standard layouts:
+         GitHub Actions  →  `<run>/<job>/<step>_<name>.txt`
+         Azure DevOps    →  `logs/<jobid>/<step-N>_<name>.log`
+         Jenkins         →  `builds/<n>/log` and `branches/*/builds/*/log`
+         GitLab CI       →  `<job>/<step>.log`
+       Recipe:
+           from pathlib import Path
+           ROOT = Path(r"<bundle-root>")
+           logs = sorted(p for p in ROOT.rglob("*")
+                         if p.is_file()
+                         and p.suffix.lower() in {".txt", ".log"})
+           print(f"LOGS: {len(logs)}")
+           for p in logs:
+               sz = p.stat().st_size
+               head = p.read_bytes()[:400].decode("utf-8", errors="replace")
+               print(f"\n=== {p.relative_to(ROOT)} ({sz} B) ===")
+               print(head)
+           # Then deep-read each one whose head matches the question
+           # using the chunked recipe in (1).
+       Specifically: a row that says "Read 0_build-and-deploy.txt and
+       subdirectory logs individually" is a TODO directed at YOU. Do
+       not write it as a finding -- execute it.
+    4. ARCHIVE-INTERIOR ENUMERATION. Never report on "the .zip"
+       without iterating EVERY member:
+           with zipfile.ZipFile(path) as zf:
+               members = zf.infolist()
+               print(f"MEMBERS: {len(members)}")
+               for m in members:
+                   print(f"  {m.filename}  {m.file_size} B")
+                   if m.file_size < 256 * 1024:
+                       data = zf.read(m).decode("utf-8", errors="replace")
+                       print(data[:1000])
+    5. DIRECTORY ENUMERATION. Never conclude "the folder contains
+       config files" from `ls`. Use:
+           paths = sorted(Path(root).rglob("*"))
+           print(f"FILES: {sum(1 for p in paths if p.is_file())}")
+           for p in paths:
+               if p.is_file():
+                   print(f"  {p.relative_to(root)}  {p.stat().st_size} B")
+       and then deep-read each one the question targets.
+    6. PAGINATED RESULT SETS (sqlite, evtx, json arrays). Use OFFSET
+       /LIMIT or generator-style iteration, NOT `LIMIT 20`. Persist
+       the cursor in `observables`.
+- A finding row whose `Status` is "incomplete" / "partial" /
+  "needs more reading" / "not fully extracted" / a `Suggested next
+  step` that paraphrases the obvious next read is forbidden. Either:
+    a) execute the next read in the SAME or NEXT turn and replace
+       the row with the completed result, or
+    b) explain in `provenance.rejected_alternatives` why the read
+       was infeasible, with the chunked attempt
+       proven by your output.
+- The `Suggested next step` column of any results table is only
+  legitimate when paired with concrete blockers. "Read X individually"
+  is not a blocker; it is the next instruction to execute. If you
+  wrote it, the next turn MUST execute it.
+
+Reporting contract (what your turns MUST leave on the record):
+
+Every investigation is graded TWICE -- once on whether the answer is
+correct, once on whether a DFIR / CTF-grade report can be produced at
+the end WITHOUT re-running the case. The report is written by a
+downstream LLM that sees only:
+
+  - the investigation question, your final answer, your confidence
+  - the full artefact snapshot (ghidra_functions / ghidra_decompilation,
+    memory enrichment derivers, network analysis, binary_analysis)
+  - your step log (command + stdout head)
+  - your `observables` dict at end-of-run
+
+`observables` is therefore the audit trail that turns a pile of
+tool-stdout into a citable report. You are REQUIRED to populate the
+following keys AS SOON AS the evidence supports each one. Keys are
+hierarchical (dot-separated) and use the artefact id or sha256[:12]

+
+Gap discipline: if a class of evidence is ABSENT (no pcap in case, no
+PE among the samples, no crypto observed) you MUST record the reason
+in observables under `gaps.<key>` -- e.g.
+`gaps.c2 = "no pcap artefact; only disk image + memory dump present"`.
+A missing key with no matching `gaps.*` entry will be treated as a
+defect by the reporting stage.
+
+Bookkeeping rule: `observables` is cumulative. NEVER drop a key that
+was set in a prior turn; only add or refine. If you discover an earlier
+entry was wrong, move it to `observables.rejected.<key>` with the
+reason, then write the corrected entry under the original key.

+You are a senior DFIR / malware-analysis engineer writing an incident-response report for a client SOC. The report is graded by a staff-level reviewer AND a CTF organiser; it MUST NOT read like generic LLM output. Every factual claim MUST be traceable to evidence you cite inline by one of: artifact_id, absolute file path, function address (`<function_name>@<0xADDR>`), or a tool-stdout excerpt tagged with the step number that produced it.
+
+# OUTPUT CONTRACT
+
+Write a single Markdown document using EXACTLY the section numbering and headings below. Every section is mandatory. If a section has no findings, write `*No findings in this layer -- see <evidence reference> for why.*` instead of omitting it. Do not add sections the contract does not list. Do not collapse sections into each other.
+
+## 1. Executive Summary
+Three sentences maximum. Who, what, when, where, impact. Cite the primary artefact.
+
+## 2. Investigation Question and Answer
+- **Question** (verbatim from the input).
+- **Answer** (verbatim, matching the answer_format from the contract).
+- **Confidence**: one of `exact`, `strong`, `medium`, `caveated`.
+- **Primary artefact**: artifact_id or absolute path.
+
+## 3. Evidence Inventory
+Markdown table with columns: `name | libmagic type | sha256 | size | path | notes`. One row per evidence file listed in the case bundle.
+
+## 4. File Identification
+Sub-section per binary-like artefact, each with:
+- libmagic description + MIME
+- architecture / bits / endianness
+- MD5 / SHA1 / SHA256 (and imphash when PE)
+- compile timestamp (only when trustworthy)
+- signature state (signed y/n, signer CN if known)
+
+## 5. Strings Analysis
+Filtered, never dumped. Use Markdown tables titled:
+- URLs / domains / IPs / bare hostnames
+- Absolute file paths
+- Registry paths
+- Mutex / event / named-pipe names
+- Crypto references (`AES`, `RC4`, `XOR`, `SHA256`, key literals)
+- Shell / LOLBIN fragments
+
+Each row MUST cite the tool (`strings`, `FLOSS`, `Ghidra`) and either the offset or the function address (`<name>@<0xADDR>`). Cap at 60 rows per table -- include only the most evidence-bearing ones.
+
+## 6. Binary Structure
+- **PE**: machine, sections with entropy flags, top imports grouped by intent, exports, TLS callbacks, overlay presence.
+- **ELF**: class, machine, dynamic symbols, notable sections.
+- **Go binaries**: build-id, module path, stripped y/n.
+
+## 7. Obfuscation & Anti-Analysis
+- Packer (`UPX`, `MPRESS`, `Themida`, `Enigma`, `VMProtect`, `garble`, or `none`).
+- String obfuscation (`XOR`, `base64`, `RC4`, `custom`).
+- Control-flow flattening evidence.
+- Anti-debug / anti-VM primitives -- reference Ghidra's `intent_map.anti_debug` function addresses when the bundle has them.
+
+## 8. Disassembly & Decompilation Highlights
+Work from the pre-collected `ghidra_functions` and `ghidra_decompilation` artefacts in the bundle. List every call-graph root that touches network / crypto / filesystem / process-creation as `<name>@<0xADDR>` with a one-sentence intent. Include 3–8 short pseudocode snippets that directly implement the malicious behaviour; NEVER paste more than 40 lines per snippet.
+
+## 9. Cryptography
+Algorithms identified, keys / IVs / salts extracted, ciphertext path + entropy, plaintext when decoded. Cite the Ghidra function + address for every primitive.
+
+## 10. C2 / Network
+Markdown table: `URL | IP | port | proto | user-agent | JA3 | beacon interval | source_step_or_artifact`. Include encoded C2 keys, XOR campaign obfuscation, and protocol format (HTTP / gRPC / protobuf / custom). Source rows from pcap artefacts AND/OR extracted strings -- cite which.
+
+## 11. MITRE ATT&CK Mapping
+Markdown table: `Tactic | Technique | ID | Evidence`. Include ONLY entries you can cite. Do not pad with speculative techniques.
+
+## 12. Indicators of Compromise
+Fenced code block formatted so an analyst can drop it straight into `iocs.txt`:
+```
+hashes:
+  <artifact>: md5=... sha1=... sha256=...
+network:
+  ip: ...
+  domain: ...
+  url: ...
+filesystem:
+  /path/...
+registry:
+  HKLM\...\Value = ...
+names:
+  mutex: ...
+  pipe: ...
+  service: ...
+  task: ...
+```
+
+## 13. CTF Hypothesis Q&A
+6–12 Q/A pairs predicting likely CTF questions. For each pair:
+- **Q**: short natural-language question.
+- **A**: exact expected answer string (matching typical CTF flag / value formats).
+- **Source**: artifact_id / path / `<function>@<0xADDR>`.
+
+Aim for breadth across the 9 phases, not depth on one finding.
+
+## 14. Timeline of Investigator Actions
+Markdown table: `# | action | tool | intent | outcome`. Chronological. One row per investigation step.
+
+## 15. Conclusions & Confidence
+Final verdict, residual unknowns, recommended follow-ups (static-only, offline).
+
+# HARD RULES
+
+- Every claim MUST cite a piece of evidence from the bundle below -- artifact_id, absolute file path, `<function>@<0xADDR>`, or `step #N`. No citation, no claim.
+- Do NOT reference any tool, capability, or workflow that is not listed under TOOL STACK. If something is absent from the bundle, say so plainly under Gaps; do NOT fill the gap with speculation.
+- Do NOT write hedging filler: "typical malware might...", "this is commonly observed", "it is worth noting", "interestingly", "notably". Either cite or omit.
+- Do NOT paste more than 40 lines of code, 60 table rows, or 80 raw strings per section.
+- Use fenced code blocks for commands, pseudocode, hex, and IOC blocks. Use Markdown tables for every list-of-rows section.
+- Pick American OR British English and stay consistent. No emojis. No marketing language.
+- Normalise timestamps to ISO-8601 UTC with second resolution.
+- When you reference a step from the investigator's timeline, cite it as `step #N`.
+
+# TOOL STACK AVAILABLE TO THE INVESTIGATOR
+
+You may reference these in the methodology section; do NOT claim the investigator used a tool whose output is not present in the step log or the artefact bundle:
+
+- dissect.target, dissect.executable, dissect.ntfs, dissect.regf
+- Volatility 3 (`windows.*`, `linux.*`, `mac.*`) with memory-enrichment derivers
+- tshark / Zeek (pcap)
+- Sysinternals strings, FLOSS, capa
+- pefile, python-magic, yara-python, pylnk3
+- Ghidra headless (pre-run by the `binary_analysis` collection lane) emitting `ghidra_functions` and `ghidra_decompilation` artefacts
+- 7-Zip, dnSpyEx, PyInstaller Extractor, signtool
+
+Return ONLY the Markdown report. No prose before or after. No meta-commentary about your own process.

-Markdown table: `# | action | tool | intent | outcome`. Chronological. One row per investigation step.
-
-## 15. Conclusions & Confidence
-Final verdict, residual unknowns, recommended follow-ups (static-only, offline).
-
-# HARD RULES
-
-- Every claim MUST cite a piece of evidence from the bundle below -- artifact_id, absolute file path, `<function>@<0xADDR>`, or `step #N`. No citation, no claim.
-- Do NOT reference any tool, capability, or workflow that is not listed under TOOL STACK. If something is absent from the bundle, say so plainly under Gaps; do NOT fill the gap with speculation.
-- Do NOT write hedging filler: "typical malware might...", "this is commonly observed", "it is worth noting", "interestingly", "notably". Either cite or omit.
-- Do NOT paste more than 40 lines of code, 60 table rows, or 80 raw strings per section.
-- Use fenced code blocks for commands, pseudocode, hex, and IOC blocks. Use Markdown tables for every list-of-rows section.
-- Pick American OR British English and stay consistent. No emojis. No marketing language.
-- Normalise timestamps to ISO-8601 UTC with second resolution.
-- When you reference a step from the investigator's timeline, cite it as `step #N`.
-
-# TOOL STACK AVAILABLE TO THE INVESTIGATOR
-
-You may reference these in the methodology section; do NOT claim the investigator used a tool whose output is not present in the step log or the artefact bundle:
-
-- dissect.target, dissect.executable, dissect.ntfs, dissect.regf
-- Volatility 3 (`windows.*`, `linux.*`, `mac.*`) with memory-enrichment derivers
-- tshark / Zeek (pcap)
-- Sysinternals strings, FLOSS, capa
-- pefile, python-magic, yara-python, pylnk3
-- Ghidra headless (pre-run by the `binary_analysis` collection lane) emitting `ghidra_functions` and `ghidra_decompilation` artefacts
-- 7-Zip, dnSpyEx, PyInstaller Extractor, signtool
-
-Return ONLY the Markdown report. No prose before or after. No meta-commentary about your own process."""

+"""RFC-09 criteria 1+2: inline system-prompt literals migrated to file-

+
+Covers the sites called out in the RFC-09 audit follow-up that do NOT
+route through :func:`aila.platform.agents.idempotent_llm.idempotent_llm_call`
+(which R1 already made stamp content_hash on its own). Each site's test
+asserts:
+
+  (a) the ``.md`` file exists under a ``prompts/`` directory the site's

+  (b) the LLM call runs inside a ``correlation_scope`` carrying the sha256

+      inside a fake client (same pattern as
+      ``tests/platform/agents/test_idempotent_correlation.py``).
+
+Scope: MASVS report-section writer, forensics writeup builder, and the
+platform ``human_cost`` estimator. The remaining sites migrated in the
+same slice (forensics investigator freeflow turn, VR advisory narrative,
+VR PoC development) are exercised through their ``_load_*_prompt`` /
+``_load_freeflow_prompt`` accessors -- the byte-identity check plus the
+compile-level presence of ``correlation_scope`` around each call is

Subject: [PATCH 268/281] feat(honesty): guard the RFC-03 agent consolidation
 against re-drift

Adds two honesty-audit rules that lock in the RFC-03 agent-runtime
consolidation so a future edit cannot silently re-duplicate what was
lifted to the platform.

- Rule 42 (agent_primitive_reimplementation) extends its lifted-primitive
  set with run_turn and the four turn helpers (decode_case_state,
  encode_case_state, auto_resolve_live_on_terminal, to_outcome_confidence)
  and now walks one level of class-body method defs, so a module subclass
  that overrides run_turn is flagged while a thin subclass and import
  re-exports stay clean.
- Rule 49 (agent_env_read, new) fires on os.environ / os.getenv access
  under modules/*/agents/**, locking in the config-drift closure that
  moved those caps to ConfigRegistry.

Both are zero-finding-clean on the current tree. Guardrails that would
false-positive on intentionally-kept code (the inline base-class prompts,
the static MCP catalog + bespoke bridges) or need unshipped infra are
deferred with reasons rather than added unsafely.

 48. platform_names_module -- a boundary-guarded file (api/, platform/, storage/) resolves a specific feature module by naming its id in a .require("vulnerability") / .require_module("forensics") call; resolve domain data by capability via ModuleRegistry.first_with/all_with instead (RFC-05 concerns a/g).
+49. agent_env_read -- a module agents/ file reads config via os.environ / os.getenv (attribute access or `from os import environ/getenv`) instead of platform ConfigRegistry; the RFC-03 lift removed every direct env read from module agent runtimes and this rule locks the closure in.

+"""RFC-driven honesty-audit guardrails.

+Tests for the guardrails that lock in RFC-03's platform-agent-runtime
+closures. Two rules:
+
+- Rule 42 (agent_primitive_reimplementation), extended in RFC-03 Phase 7
+  from the two Phase-1 primitives (``classify_intent``,
+  ``maybe_post_auto_steering``) to also cover the turn-runner lift:
+  ``run_turn``, ``decode_case_state``, ``encode_case_state``,
+  ``auto_resolve_live_on_terminal``, ``to_outcome_confidence``. The check
+  now walks class-body method defs too so a subclass that overrides
+  ``run_turn`` on an ``AgentTurnRunnerBase`` subclass fires.
+
+- Rule 49 (agent_env_read), the config-drift closure guard. Modules under
+  ``aila/modules/*/agents/**`` must resolve config through
+  ``ConfigRegistry`` and never touch ``os.environ`` / ``os.getenv``
+  directly.
+
+Each rule has positive tests (a synthetic violation fires) and negative
+tests (thin subclasses, out-of-scope files, and import re-exports stay
+clean). A final gate test runs the full audit on ``src/aila`` and
+asserts exit 0 with zero findings, matching the CI contract.

Subject: [PATCH 269/281] feat(template): scaffold platform config + registry
 declarations (RFC-04/05)

Makes _template demonstrate the platform primitives so a module copied
from it starts boundary-clean. Adds TemplateConfigSchema subclassing
ModuleConfigBase (extra='forbid' posture, example fields), declares the
ModuleProtocol registry methods (reasoning_strategies,
reasoning_domain_profiles, workflow_definitions) as documented typed stubs
using only public platform imports, registers the config schema in
register_tools mirroring the real modules, and turns services/__init__
into a pointer at the platform investigation-support bases. The
investigation-agent engine stays out of _template by design -- it is a
simple-action scaffold, and the reusable agent template is the platform
bases plus the two reference modules.

Subject: [PATCH 270/281] docs(changelog): document the investigation-engine
 extraction program

Adds an Unreleased section covering RFC-01 through RFC-12 and the
faithfulness-remediation pass: the platform agent runtime and primitive
consolidation, prompt versioning + deployment + per-investigation
pinning, the eval-gated agent lifecycle with a review quorum, the MCP
instance catalog, knowledge provenance, self-healing, and the honesty
guardrails that lock it in. Flags the two operator-facing contract
changes (the AILA_VR_/AILA_MALWARE_ env-var rename and the
promotion-quorum gate). The version number is set at the dev-to-main
release.

+## [Unreleased] -- Investigation-engine extraction program (RFC-01 through RFC-12)
+
+The vulnerability-research and malware investigation engines are unified
+onto a shared platform: one turn runner, one tool executor, one set of
+support services and data-model bases, one agent primitive per concern.
+Modules now bind their record types, prompts, and gates to platform bases
+instead of carrying parallel copies. Also adds prompt versioning and
+deployment, an eval-gated agent lifecycle, a DB-backed MCP catalog, and
+per-vector knowledge provenance. Read the Changed section: the agent
+config env-var names and the promotion contract changed and may require
+operator action.
+
+### Added
+
+- Platform agent runtime (RFC-03): `AgentTurnRunnerBase`,
+  `ToolExecutorHelpersBase`, the shared turn helpers, and platform bases
+  for the pattern extractor, claim verifier, synthesis runner, persona
+  router, and outcome dispatcher. The vr and malware agents are thin
+  subclasses that set class attributes and override hooks; no agent
+  primitive is defined twice. Honesty rules 42 and 49 lock this in.
+- Prompt registry, immutable version store, and an admin deploy API so a
+  prompt change ships by an alias flip with no code release (RFC-09,
+  migrations 086/087/089). Every LLM call routed through the idempotency
+  wrapper now records a `prompt_content_hash`, and cost + seal records
+  gain a `prompt_version` column (migration 094).
+- Per-investigation prompt pinning: an investigation resolves and pins its
+  prompt versions on first use, so a later production-alias flip does not
+  re-route a running investigation (migration 095).
+- Eval-gated prompt promotion (RFC-08, migration 090) and an agent
+  lifecycle control plane with evaluate/approve/promote/rollback, a
+  distinct-approver review quorum, and an admin HTTP surface (RFC-10,
+  migration 091).
+- DB-backed MCP server instance catalog with a live-resolving registry and
+  an admin CRUD API, so a server can be added, disabled, retargeted, or
+  duplicated with no code change or worker restart (RFC-11, migration
+  092).
+- Content-aware knowledge chunker and per-vector provenance (`model_id`,
+  `content_hash`, `source_type`, `updated_at`) on knowledge entries
+  (RFC-12, migration 093).
+- Self-healing infra-death classifier that marks a multi-turn
+  infra-failed investigation retryable instead of emitting a hollow
+  no-finding outcome, plus an `aila_sse_write_failures_total` metric
+  replacing silent SSE-write swallows (RFC-07).
+- `_template` now scaffolds a `ModuleConfigBase` config schema and the
+  ModuleProtocol registry declarations so a copied module starts
+  boundary-clean.
+
+### Changed
+
+- Investigation lifecycle, support services, and data-model bases are
+  hoisted to the platform and shared by both modules (RFC-01/02/04);
+  modules bind their record and enum types. The platform never imports a
+  module (RFC-05), enforced by honesty rules 44 through 48.
+- Agent submit-gate caps resolve through `ConfigRegistry`. The operator
+  env-var names change from the raw `VR_*` / `MALWARE_*` form to the
+  standard `AILA_VR_<KEY>` / `AILA_MALWARE_<KEY>` form; defaults are
+  unchanged, so an operator who never set the old names sees no
+  difference.
+- Agent-behavior promotion now requires the eval gate AND a distinct
+  -approver quorum (`agent_promotion_quorum`, default 1) before the
+  production alias flips.
+
+### Fixed
+
+- The shared search router derived a finding result's `module_id` from a
+  hardcoded `"vulnerability"` literal even though the module was resolved
+  by capability; it now reads the resolved module's id, so a second
+  module exposing findings is labeled correctly.
+
+### Removed
+
+- Duplicated agent primitives, support services, and data-model records
+  across the vr and malware modules, consolidated onto the platform bases
+  above.
+
+---
+

Subject: [PATCH 271/281] feat(resilience): single ResilienceLayer facade over
 the fail-open sites (RFC-07)

Closes RFC-07 acceptance bullet 2. The recovery-service duplication the
bullet targets was already removed by RFC-04 (the module recovery files
are functools.partial bindings over platform functions), and step 0's
fail-closed conversions + SSE-failure counter already shipped; the genuine
gap was the single ResilienceLayer the Design sketches.

New platform/services/resilience.py exposes one facade -- classify_failure
(delegating to InfraDeathClassifier), should_retry, conservative_default,
and record_signal -- with a RecoveryPolicy and a FailureVerdict. A new
aila_resilience_signals_total{op,source} umbrella counter funnels every
fail-closed signal; record_signal also mirrors the existing
aila_sse_write_failures_total so operator dashboards read unchanged. The
queue defer, SSE emitter, workflow-log emit, and finalizer classifier
sites now route through the layer instead of each carrying its own
log-then-metric-then-return. The verify + pipeline steps already re-raise
(fail-closed) and are unchanged. 35 layer tests plus the existing
fail-closed + infra-death tests pass.

+"""RFC-07 ResilienceLayer -- single facade over the platform recovery
+primitives.
+
+Premise verification (2026-07-24). The RFC-07 acceptance bullet 2 asked
+for "a single platform ResilienceLayer replaces the five duplicated
+recovery services; no recovery service exists in two module copies." The
+duplication half of that claim was already satisfied by RFC-04: the
+recovery services (investigation reaper, investigation finalizers, stall
+recovery, branch reaper, auto-steering) live once under
+``aila.platform.services`` / ``aila.platform.agents``; the files at
+``aila.modules.<mod>.services.*`` are thin ``functools.partial``
+bindings that inject the module record models and config. The genuinely
+missing half was the coherent policy facade -- each fail-open site
+carried its own conservative-default value AND its own metric bump AND
+its own log line, so a fix to the pattern touched five files. This
+module is that facade: one place that answers
+
+* does this exception class look like infrastructure death,
+* what is the conservative default for a given operation,
+* which failure signal metric fires and with what labels.
+
+The facade is intentionally thin. It does NOT re-implement the pure
+:class:`InfraDeathClassifier`, does NOT re-implement the reaper /
+finalizer / stall sweeps, and does NOT change the observable
+fail-closed behaviour shipped in RFC-07 step 0. Every call site keeps
+its existing default value and existing raise / return semantics. What
+changes: the value + metric bump route through the same helper so the
+umbrella :data:`aila_resilience_signals_total` counter fires from one
+place, and adding a new fail-closed site is one call rather than three
+copy-paste lines.

Subject: [PATCH 272/281] feat(eval): experience writer, calibration proposer,
 routing learner (RFC-08)

Closes RFC-08 criteria 3-5, the self-improvement loop that sits behind the
already-shipped eval gate. All three are platform services generic over
injected record types (no module import).

- ExperienceWriter turns a reviewed outcome into a signed pattern in the
  PatternStore: a positive pattern on an accept verdict, a negative one on
  a reject so retrieval can down-weight a rejected approach. It reuses the
  PatternStore create path rather than duplicating signing.
- CalibrationProposer aggregates accept/reject history per outcome_kind
  into a versioned, reversible confidence-threshold proposal
  (eval_calibration_proposals, migration 097; status active/superseded/
  reverted). Proposals are advisory -- application still goes through the
  eval gate and the lifecycle, never auto-applied.
- RoutingLearner turns outcome + cost history into a typed routing
  recommendation. The pre-execution sizing consumer (#23) does not yet
  exist, so the recommendation is exposed and published as
  recommendation-only rather than wired to a nonexistent seam.

Real aggregation over real history rows; tests cover positive/negative
pattern writes, a versioned+reversible proposal, and a recommendation.

+"""RFC-08 step 2: per-outcome_kind calibration proposer + versioned journal.
+
+The observed overstatement bias -- accepted low-severity, rejected
+high-severity -- is a per-``outcome_kind`` signal in the accept/reject
+history that the operator's review quorum already writes. ``CalibrationProposer``
+turns that history into a threshold-adjustment proposal without ever
+mutating the live threshold: application is gated by the RFC-08 eval +
+review quorum, per the propose-and-gate contract.
+
+Storage: :class:`CalibrationProposalRecord` is an append-only journal of
+proposals. Each row carries the before / after threshold values plus the
+sample counts it was derived from. Reversibility is expressed as a chain
+of rows -- reverting a proposal never rewrites the original row; it
+inserts a new proposal that flips the before/after values and stamps
+``superseded_by`` on the target. Every historical decision stays
+grep-able against the row that produced it.
+
+Constraint + index names carry the ``eval_calibration_proposals_`` prefix
+so they stay unique across the platform schema (Postgres constraint
+names are database-scoped, not table-scoped -- the same lesson eval and
+prompt tables learned).
+
+The proposer's aggregation logic is deliberately conservative:
+
+* ``min_evidence`` samples per kind before a proposal is allowed to
+  suggest a threshold move at all. Under-supported proposals return
+  ``None`` so noise cannot chase the threshold up.
+* A raise fires only when high-confidence rejects OUTNUMBER the sum of
+  approves and low-confidence rejects at the same confidence band --
+  the operator was rejecting confidently-stated findings, so the bar
+  needs to be higher than that confidence band. The new threshold is
+  the mean of the high-confidence-reject confidences plus ``margin``.
+* A drop fires only when high-confidence approvals crowded above the
+  current threshold and there were essentially no rejects at that
+  band -- the current threshold is over-cautious and dropping it in
+  by ``margin`` unlocks accepted findings the panel already agreed on.
+* If neither condition holds, ``before == after`` and the proposal
+  carries a "no adjustment recommended" reasoning -- still logged so
+  the review pass sees that the proposer LOOKED.

+"""RFC-08 step 1: turn a reviewed outcome into a signed pattern.
+
+The outcome-review quorum (``platform/services/outcome_review.py``) writes
+one of three terminal verdicts onto a draft outcome: ``approved`` (siblings
+reached the approve quorum), ``rejected`` (reject-quorum veto), or the row
+stays ``draft`` (undecided). ``ExperienceWriter`` consumes an already-
+evaluated ``QuorumOutcome`` and writes a matching signed row into the
+module's ``PatternStore`` -- a positive pattern on approve, a NEGATIVE
+pattern on reject. Draft / abstain / no-transition results write nothing.
+
+Negative signing carries three signals so a retrieval that ranks patterns
+purely on similarity still sees the down-weight:
+
+* ``applicability["polarity"] = "negative"`` -- structured filter available
+  to any caller that wants to skip or discount negatives (RFC-08 says the
+  negative "lowers a prior, does not hard-block").
+* ``confidence = PatternConfidence.CAVEATED`` -- the lowest confidence in
+  the platform enum (``EXACT``, ``STRONG``, ``MEDIUM``, ``CAVEATED``,
+  ``UNKNOWN``); the mirrored KnowledgeEntry's metadata carries the same
+  caveated confidence so the pgvector rank sees a down-weight signal.
+* summary prefix ``[NEGATIVE] `` so an operator inspecting the pattern
+  catalog sees the polarity without opening the JSON.
+
+Generic over the module: the writer takes the module's ``PatternStore`` and
+its ``PatternCreate`` class as constructor deps; the platform never names a
+specific module. The ``pattern_kind`` (module's ``PatternKind`` enum value)
+is passed by the caller because platform code cannot enumerate module
+vocabulary (honesty rule 48).
+
+The writer never touches the eval gate or the promotion path. Recording a
+pattern is an OBSERVATION of the review verdict; whether that pattern
+influences future prompts is decided later by the retriever + relevance
+floor + the eval harness, per the propose-and-gate contract.

+"""RFC-08 step 3: turn historical outcome + cost data into a routing recommendation.
+
+The reward signal for routing is the same accept/reject verdict the review
+quorum writes, joined against the ``task_type`` (or persona role) that
+served the LLM calls on the branch that produced the outcome. Cost is the
+per-call USD amount from :class:`LLMCostRecord` for the same run. The
+learner combines the two into a per-task-type score for a given
+``target_kind`` -- approval rate discounted by mean cost -- and returns a
+:class:`RoutingRecommendation` listing task types ranked by that score.
+
+The recommendation is a proposal only. It does NOT flip any live routing
+switch; whether the recommendation is USED by pre-execution sizing is the
+sizing layer's decision, which itself is gated by the RFC-08 eval + review
+quorum contract. The learner exposes the recommendation and reports the
+sizing seam.
+
+Pre-execution sizing seam (RFC-10 SHADOW / CANARY stages, cross-ref #23):
+The lifecycle stage vocabulary declares ``SHADOW`` and ``CANARY`` as
+reserved-for-later stages (``platform/lifecycle/models.py``); the
+controller has no path from ``EVALUATED`` to either stage today, and no
+platform component consumes a ``RoutingRecommendation`` at branch spawn
+time. Branch creation flows through ``BranchPool`` operations
+(``platform/agents/branch_pool.py``) that take a fixed persona / voice
+argument, not a sizing hint. Until that seam lands, the learner
+publishes the recommendation via ``recommend_from_history`` and the
+async ``recommend`` variant that wraps a caller-supplied history
+provider; a caller can consume the recommendation manually. Wiring the
+recommendation into an automatic pre-execution sizing input is deferred
+to the follow-on that ships the SHADOW / CANARY stage transitions in the

+"""Tests for the RFC-08 self-improvement services.
+
+Three services covered:
+
+* :class:`ExperienceWriter` -- writes a positive pattern on an approved
+  review verdict and a negative pattern on a rejected one; skips draft /
+  no-transition tallies. The pattern rows are asserted directly against
+  ``vr_patterns`` so the pair-write (module patterns table + knowledge
+  mirror) is exercised end-to-end.
+* :class:`CalibrationProposer` -- aggregates a synthetic accept/reject
+  history into a threshold-adjustment proposal; the persist path writes
+  a versioned :class:`CalibrationProposalRecord`; the revert path writes
+  a REVERTING row and flips the target's status.
+* :class:`RoutingLearner` -- ranks task types for a target_kind by
+  approval rate discounted by cost; a high-approval / low-cost task type
+  ranks above a low-approval / high-cost one on the same synthetic
+  history.
+
+Importing :class:`CalibrationProposalRecord` at module scope registers the
+``eval_calibration_proposals`` table on ``SQLModel.metadata`` so the
+shared ``test_db`` fixture's ``create_all`` builds it -- the migration
+lands via the orchestrator; tests do not need it.
+
+The ExperienceWriter test uses the VR concrete PatternStore + a stubbed
+KnowledgeService so the platform-side write path is exercised without
+depending on a live embedding provider (mirrors
+``tests/test_pattern_store_floor.py``).

Subject: [PATCH 273/281] feat(lifecycle): shadow + canary stages with cohort
 routing (RFC-10)

Closes RFC-10 criterion 2's shadow/canary path and criterion 5's
hold/alert. The controller gains shadow(), canary(cohort_percent),
promote_from_canary() (still eval + quorum gated), record_canary_signal(),
and the resolvers active_shadow / active_canary /
resolve_version_for_investigation. A shadow registers a candidate for
comparison without production traffic; a canary routes a stable cohort
fraction of NEW investigations to the candidate by a SHA-256 bucket of the
investigation id; a drift or cost sample past the configured ceiling flips
the active canary to a HELD state and raises a signal. Assignments live in
lifecycle_canary_assignments (migration 096); ceilings are
agent_canary_drift_ceiling + agent_canary_cost_ceiling_usd on
PlatformConfigSchema. admin_lifecycle gains POST /shadow, /canary,
/canary/signal and GET /route. 16 tests cover registration, stable cohort
bucketing, the hold-on-spike path, and the gated promote-from-canary.

+"""096 -- lifecycle canary/shadow assignments (RFC-10 steps 1-2).
+
+Backs the shadow + canary stages of the agent development lifecycle. A
+shadow row registers a candidate version for comparison without production
+traffic; a canary row routes a stable cohort fraction of new investigations
+to a candidate; a drift or cost spike flips the active canary to a held
+state. resolve_version_for_investigation reads the active canary and buckets
+by a hash of the investigation id. Columns match
+platform/lifecycle/assignments.py so create_all (tests, fresh installs)

+"""RFC-10 shadow + canary assignment table.
+
+A ``LifecycleCanaryAssignment`` row records the platform's intent to
+route some traffic to a non-production candidate: a ``shadow``
+assignment says "this candidate is being compared but never wins a real
+turn"; a ``canary`` assignment says "route ``cohort_percent`` of new
+investigations to this candidate deterministically by hash".
+
+The table is mutable because a canary can be HELD when the drift or
+cost signal breaches its ceiling, and a prior shadow / canary for the
+same key is superseded on a new one. The append-only story lives on
+``lifecycle_transitions``; this table is the routing-side lookup the
+runtime consults on every new investigation.
+
+Constraint and index names carry the ``lifecycle_canary_assignments_``
+prefix so they stay unique across the platform schema (Postgres
+constraint names are database-scoped, not table-scoped -- the same
+lesson eval, prompt, and lifecycle-transition tables learned).

Subject: [PATCH 274/281] feat(mcp): generic McpClient, capability dispatch,
 instance pooling (RFC-11)

Advances RFC-11 through steps 0/3/4 plus call provenance. A new generic
McpClient owns the transport that was duplicated inside the three bridges;
each bridge now resolves its endpoint through the shared resolve_instance
(preserving the env>config>catalog>default precedence and the byte-
identical empty-catalog fallback) and keeps only its genuinely server-
specific request/response shaping, which RFC-11 section 6 permits as
plugin-side rendering. The registry gains resolve_by_capability, bind, and
pool_for_capability; the researchers resolve servers by declared
capability tag from the catalog (falling through to the name map when the
catalog is empty) instead of a hardcoded kind->server list, and an
InstancePool round-robins across enabled rows of one capability. Every
call records the serving instance_id (new column on the shared
McpCallLogRecordBase, migration 098, on both module call-log tables).

The three bespoke bridge classes are not deleted: after transport
unification their remaining bodies are legitimate server-specific adapters
(JADX rewrite, IDA name coercion, APK path resolution), not duplicated
transport. 23 client tests plus the catalog + bridge tests pass.

+"""RFC-11 -- generic MCP client, resolver, and capability instance pool.
+
+One :class:`McpClient` replaces the three bridges' hand-rolled HTTP
+transport, ``GET /tools`` fetch, ``POST /tools/<action>`` dispatch,
+JSON parsing, and per-call audit-log recording. The bridge classes are
+kept as thin adapters that layer server-specific request/response
+shaping (JADX path rewriter, IDA auto-name coercion, android-mcp
+pipeline-only guard) on top of this generic transport -- see the audit
+report on RFC-11 step 5 for which bridges could not collapse fully.
+
+Three cooperating pieces:
+
+* :class:`ResolvedInstance` -- resolver output; carries the URL, the
+  source tier that produced it (``env`` > ``config`` > ``catalog`` >
+  ``default``), the catalog row id when known, and the catalog's
+  capability tags. ``instance_id`` is threaded into the per-call
+  audit log so a finding's provenance records which physical server
+  instance produced each reading (RFC-11 §7 provenance).
+* :func:`resolve_instance` -- the shared 4-tier resolver used by the
+  :class:`~aila.platform.mcp.registry.McpRegistryServiceBase` and by
+  every :class:`~aila.platform.tools.Tool` bridge. Byte-identical to
+  the pre-catalog behaviour when the catalog is empty for a scope so
+  the operator's live dispatch is unchanged.
+* :class:`InstancePool` -- round-robin selector for two or more
+  enabled catalog rows advertising the same capability. Callers ask
+  for one instance per invocation via :meth:`InstancePool.next`; the
+  pool rotates a monotonic counter under an async lock so concurrent
+  callers on the same event loop see interleaved picks. Empty pools
+  raise :class:`EmptyPoolError` so the caller decides whether to fall
+  back to the static default or surface the outage.
+
+Every :meth:`McpClient.call_tool` invocation records the resolved
+``instance_id`` (or ``None`` when no catalog row applied) via the
+module's ``record_call`` async context manager. The call-log column
+``instance_id`` on :class:`~aila.platform.contracts.mcp_call_log_base
+.McpCallLogRecordBase` receives the value; the operator UI joins
+audit rows to the catalog row on this key.

Subject: [PATCH 275/281] chore(db): register calibration + canary tables for
 create_all and autogen

Adds the bottom-of-file side-effect imports for CalibrationProposalRecord
(RFC-08, eval_calibration_proposals) and LifecycleCanaryAssignment
(RFC-10, lifecycle_canary_assignments) so SQLModel.metadata sees both
tables on the create_all path and Alembic autogen, matching migrations 097
and 096.

Subject: [PATCH 276/281] feat(eval): record-replay retrieval quality eval
 (RFC-12)

Closes RFC-12 criterion 7. A retrieval benchmark records queries with
per-query ground-truth relevant ids; RetrievalEvalRunner.run replays each
query through an injected retrieve function, scores the ranked ids with
precision@k, recall@k, MRR, nDCG@k, and MAP, and applies a beats() gate so
a retrieval change is eval-gated the way prompt changes are. Two tables
back it (retrieval_eval_benchmarks + retrieval_eval_runs, migration 099),
mirroring the prompt-eval harness. The runner takes the retrieve function
by injection, so the platform eval layer does not import a module. Real
metric math, verified against hand-built ranked lists; 30 tests.

+- ``recall_at_k(ranked, relevant, k)`` -- fraction of the relevant ids

+- ``reciprocal_rank(ranked, relevant)`` -- ``1/rank`` of the first

+- ``mean_reciprocal_rank`` -- mean of per-query reciprocal ranks.

+- ``average_precision`` / ``mean_average_precision`` -- classical AP and

+"""Retrieval eval runner: record-replay a benchmark and gate promotion.

+RFC-12 criterion 7. The runner takes a ``retrieve_fn`` by injection so

+generic: today the candidate is ``KnowledgeService.retrieve`` bridged
+through an adapter that returns ranked ids; tomorrow a hybrid or graph
+retriever swaps in through the same injection point.
+
+Runner flow
+-----------
+1. Load the benchmark row -- raise ``RetrievalBenchmarkNotFoundError``

+2. Replay every recorded query through ``candidate_retrieve_fn`` at the
+   benchmark's fixed ``k``; score each case; aggregate into a candidate
+   ``RetrievalReport``.
+3. When ``baseline_retrieve_fn`` is supplied, repeat the replay through
+   it and aggregate a baseline ``RetrievalReport``. When it is None,
+   the run has no comparison baseline for this event.
+4. Verdict:
+   - baseline supplied AND ``candidate.beats(baseline, tol)`` -> ``pass``
+   - baseline supplied AND not-beats                          -> ``fail``
+   - no baseline AND ``first_eval_auto_passes`` True          -> ``pass``

+"""Tests for the RFC-12 criterion 7 record-replay retrieval eval harness.
+
+Covers three layers:
+
+1. Pure metrics on hand-constructed ranked lists vs a known relevant set
+   -- exact numeric assertions so a metric drift shows up as a failure.
+2. The runner replays a benchmark through a fake ``retrieve_fn`` and
+   persists a scored report row (create_all-backed DB fixture).
+3. ``RetrievalReport.beats`` accepts a strict improvement and rejects a
+   regression beyond tolerance so a retrieval change is eval-gated the
+   same way a prompt change is.

Subject: [PATCH 277/281] feat(knowledge): adaptive routing, stable-core CAG,
 graph path, result gate (RFC-12)

Closes RFC-12 criteria 4, 5, and 6 on the retrieval path. A KnowledgeRouter
classifies a query to one of three paths: stable-core (a preloaded cache
of designated entries returned without a vector search), simple (the
existing hybrid vector + FTS + relevance floor, unchanged so current
callers are unaffected), or graph (multi-hop). The graph path adds a
knowledge_entry_edges table (migration 100) and a bounded BFS traversal
that follows labelled edges from a seed match with a hop cap. Every
returned result passes a sanitize/classify gate and carries its provenance
(model_id, content_hash, source_type, updated_at). retrieve_routed exposes
the router; the agent-facing KnowledgeRetrieveTool consults it. 26 tests.

+"""Retrieval sanitize/classify + provenance gate -- RFC-12 criterion 6.
+
+Every knowledge hit returned to a caller passes through :func:`apply_gate`,
+which does three things without touching the underlying entry row:
+
+* Runs the content through :func:`sanitize_input` (the same untrusted-input
+  scrubber the LLM pipeline uses) and stamps ``sanitized_content`` +
+  ``content_sanitized`` on the hit. The original ``content`` is kept
+  verbatim so a caller that wants the raw bytes can still see them; a
+  caller emitting into a prompt reads ``sanitized_content``.
+* Classifies the content via :func:`classify_messages` and adds
+  ``classification`` (``"public"`` / ``"internal"`` / ``"restricted"``).
+  RESTRICTED hits are annotated with the pattern types that fired so the
+  caller can decide whether to redact them further before use.
+* Copies the provenance columns (``model_id``, ``content_hash``,
+  ``source_type``, ``updated_at``, ``created_at``, ``namespace``) into a
+  nested ``provenance`` dict on the hit. RFC-12 criterion 6 requires every
+  retrieved item to carry provenance; centralising the extraction here
+  avoids each caller redoing the column reads or forgetting a field.
+
+The gate is pure (no I/O, no globals mutated) so it composes cleanly with
+the different retrieval paths and stays trivially unit-testable. It also
+does not mutate its input dict; a new dict comes back so callers who
+retained a reference to the raw hit see the pre-gate shape.

+"""Knowledge-entry relational graph -- RFC-12 criterion 5 (graph multi-hop).
+
+Adds a real relation between :class:`KnowledgeEntryRecord` rows so multi-hop
+questions ("how does X relate to Y") can be answered by traversing edges
+rather than by embedding a compound query and hoping cosine-similarity
+returns every hop as its own top-k row. The naive-RAG failure mode the
+RFC names -- facts that live in relationships, not in any one chunk -- is
+exactly the class this table handles.
+
+Two things ship here:
+
+* :class:`KnowledgeEntryEdge` -- the SQLModel/table for edges. src -> dst
+  labelled by ``relation`` with a scalar ``weight``. A UNIQUE constraint on
+  ``(src_id, dst_id, relation)`` prevents duplicate edges under the same
+  label so ``add_edge`` is idempotent per (src, dst, relation).
+* :class:`KnowledgeGraph` -- the service. ``add_edge`` writes; ``traverse``
+  runs a bounded BFS from a seed set, returning every reachable
+  ``KnowledgeEntryRecord`` row along with its hop depth and the edge that
+  reached it. Traversal is capped by ``max_hops`` (hop 0 = the seed itself,
+  hop 1 = direct neighbours, ...) and by ``max_nodes`` so a pathological
+  fan-out cannot exhaust the process.
+
+The table is defined in this module (not ``storage/db_models.py``) so the
+retrieval slice owns its schema end-to-end. It is registered with
+``SQLModel.metadata`` on import; the orchestrator wires the Alembic
+migration and adds an ``import aila.platform.services.knowledge_graph`` to
+``db_models`` so ``create_all`` picks the table up on fresh installs / in

+"""Adaptive retrieval router -- RFC-12 criterion 4.
+
+Classifies a knowledge query into one of three retrieval paths so the
+cheapest adequate strategy runs on every request. The three routes come
+straight from the RFC design pseudocode:
+
+* :data:`Route.STABLE_CORE` -- the query targets the small, hot, stable
+  corpus preloaded into memory (rubrics, accept-bar policies, verified
+  prior verdicts). Served from the CAG cache without a vector call.
+* :data:`Route.SIMPLE` -- the default single-shot hybrid path
+  (:meth:`KnowledgeService.retrieve`): pgvector + FTS merged and floored.
+* :data:`Route.GRAPH` -- multi-hop questions whose answer lives in the
+  relations between entries. Served by :class:`KnowledgeGraph.traverse`
+  seeded from a small hybrid lookup.
+
+The classifier is a rule-based heuristic keyed on lexical shape, not a
+learned model -- the RFC design admits this explicitly: "adaptive
+routing" here means a real dispatch that measurably differs across
+inputs, not an ML classifier we haven't paid to train. Each route below
+carries the exact rule that fires it so operators (and later tests) can
+audit the decision without reading Python.

+"""Cache-Augmented Generation (CAG) stable-core cache -- RFC-12 criterion 5.
+
+Preloads the small, stable knowledge subset (rubrics, accept-bar policies,
+verified prior verdicts -- the exact material the RFC lists as CAG
+candidates) into a process-local list once, then serves stable-core queries
+from that list without an embedding call, an FTS query, or a hybrid merge.
+
+Membership rule: an entry is stable-core iff its ``namespace`` starts with
+:data:`STABLE_CORE_NAMESPACE_PREFIX`. Using the existing namespace
+mechanism -- rather than adding a marker column -- keeps the change
+migration-free at the schema level (no column, no index, no backfill) and
+matches how the platform already scopes ownership per D-09
+(``platform:*`` = shared admin data). Operators promote an entry to the
+stable core by writing it into ``platform:stable_core:<key>``; demoting
+means moving it back to a regular namespace.
+
+The cache is process-local (a plain list guarded by a thread lock) and
+opts callers into explicit invalidation:
+
+* :meth:`StableCoreCache.preload` runs the single SELECT and populates
+  the cache; safe to call repeatedly (idempotent) but only reloads when
+  invalidated or forced.
+* :meth:`StableCoreCache.entries` returns the cached rows, running
+  :meth:`preload` on the first call.
+* :meth:`StableCoreCache.invalidate` clears the cache so the next
+  :meth:`entries` call reloads from the DB.
+
+Cache staleness is real (RFC-12 lists it as a CAG hazard). Writers into
+the stable-core namespace SHOULD call :meth:`invalidate` after their
+commit; the retrieval slice does not own that hook, so the enrichment
+slice will wire it into ``KnowledgeService.store`` alongside the other

Subject: [PATCH 278/281] chore(db): register retrieval-eval + knowledge-edge
 tables

Adds the side-effect imports for RetrievalBenchmarkRecord /
RetrievalRunRecord (RFC-12 eval, migration 099) and KnowledgeEntryEdge
(RFC-12 graph, migration 100). The knowledge-edge import lands at the end
of the module, after every record class is defined, so the transitive
db_models references in the knowledge-graph import chain resolve without a
circular import.

Subject: [PATCH 279/281] feat(knowledge): opt-in contextual chunk enrichment
 on ingest (RFC-12)

Closes the enrichment half of RFC-12 criterion 2. KnowledgeService.store
gains an opt-in enrich flag (default off, so the current path stays byte-
identical); when on, each chunk gets a short LLM-written blurb situating it
in its parent document, prepended before embedding so the vector and the
FTS search text both carry the context. The blurb prompt is a registry
.md file (no inline literal), the call routes through idempotent_llm_call,
and entry_metadata records the blurb + the original chunk text so the raw
chunk stays recoverable. No schema change -- metadata rides the existing
entry_metadata JSON. The enrich_chunk import is deferred to the call site
to avoid a module-load import cycle. 4 tests cover the on/off paths.

+You situate a knowledge-base chunk inside its parent document so a retrieval
+embedding of the chunk carries enough context to be found on questions phrased
+in the vocabulary of the whole document, not only in the vocabulary of the
+chunk itself. This is the ingestion-side half of RFC-12 contextual enrichment
+(the "contextual retrieval" recipe): you write ONE short blurb that will be
+prepended to the chunk text before embedding.
+
+You will receive a JSON object with two fields:
+
+  - ``document``: the full parent document the chunk was cut from. May be long;
+    read it as background, do not summarise it in the output.
+  - ``chunk``: the exact chunk text that is about to be embedded and stored.
+
+Return PLAIN TEXT only (no JSON, no markdown headings, no code fences, no
+prefix like "Context:"). The plain text is exactly what gets prepended.
+
+Rules for the blurb:
+
+  1. 1 to 3 short sentences, 50 to 100 tokens total. NEVER longer.
+  2. State where this chunk sits in the parent document (which section /
+     function / concept it is part of) and what it is about, using terms
+     drawn from the parent document so a query using document-level
+     vocabulary still finds this chunk.
+  3. NEVER quote or repeat the chunk. NEVER paraphrase it line by line. The
+     chunk itself will be appended verbatim under your blurb; your job is
+     situation, not summary.
+  4. NEVER invent facts. If the parent document does not name the section
+     or role the chunk plays, say so in one clause and stop.
+  5. English only. Neutral technical voice. No filler openings ("This chunk
+     is...", "In this section..."), no meta commentary about the task.

+"""Contextual chunk enrichment for knowledge ingestion (RFC-12 criterion 2).
+
+The chunker in :mod:`aila.platform.services.ingestor` produces
+boundary-aligned chunks; this module adds the situating half of the RFC-12
+criterion. For each chunk we ask the LLM to write a 50 to 100 token blurb
+saying WHERE the chunk sits inside its parent document. The blurb is
+prepended to the chunk BEFORE embedding, so the stored vector carries
+document-level terms the chunk itself may not repeat. The original,
+unenriched chunk stays recoverable via ``entry_metadata["chunk_original"]``
+and the generated blurb is captured under ``entry_metadata["context_blurb"]``.
+
+Cost note: enrichment is one LLM call per chunk. Ingesting a 10-chunk
+document with enrichment enabled pays for 10 chat completions on top of
+the embedding calls. For that reason enrichment is opt-in on every call
+(``store(..., enrich=True)``); the default path is byte-identical to the
+unenriched baseline.
+
+The prompt lives in ``src/aila/platform/prompts/system_knowledge_enrichment.md``
+via the file :class:`aila.platform.prompts.PromptRegistry` (RFC-09 criterion 1:
+no inline literal system prompts in code). The LLM call goes through
+:func:`aila.platform.agents.idempotent_llm.idempotent_llm_call` so a retried
+worker replays the cached blurb instead of paying for a second completion.

+"""RFC-12 criterion 2 -- contextual enrichment on ingestion.
+
+The chunker in :mod:`aila.platform.services.ingestor` already ships the
+"code/doc boundary" half of criterion 2. This suite covers the
+enrichment half: when :func:`KnowledgeService.store` is called with
+``chunked=True, enrich=True`` and the service was built with an
+``llm_client``, each chunk gets an LLM-written blurb prepended before
+embedding, and the original chunk text is recoverable from
+``entry_metadata``.
+
+Two hard guarantees under test:
+
+  1. Enrichment ON path -- the embedded ``content`` includes the
+     generated blurb; ``entry_metadata`` records ``context_blurb`` and
+     ``chunk_original`` separately; the LLM (mocked at the idempotent
+     seam) is called exactly once per chunk.
+
+  2. Enrichment OFF path (default) -- ``store()`` is byte-identical to
+     the pre-enrichment behaviour: no LLM call, no new metadata keys, no
+     blurb prepended.
+
+The LLM is mocked at the idempotent seam
+(:func:`aila.platform.services.knowledge_enrichment.enrich_chunk`
+patches the idempotent wrapper) so no model / provider / cache setup is
+needed. The embedding provider is stubbed to a zero vector so the real

Subject: [PATCH 280/281] fix(lifecycle): key workflow cursors by investigation
 + branch (RFC-02)

Closes the RFC-02 Class-A cursor-keying defect. Cursor rows were keyed by
the random ARQ task uuid, so the lifecycle service's investigation-scoped
pause/resume queries matched zero rows and fell through to weaker
fallbacks. WorkflowStateCursor gains investigation_id + branch_id columns
(migration 101, both nullable + indexed); the engine populates them at
cursor creation from the run input, and pause/resume/purge query by them.
resume drives its fan-out with the real branch id rather than the task
uuid. The run_id ANY(...) legacy fallback is kept so investigations whose
cursor predates this change still resume. Non-investigation workflows
leave the columns null.

Unit tests pin creation, the investigation-scoped find, resume restore
with the correct branch id, and both legacy fallbacks. Live pause/resume
on a running investigation is an operator smoke gate at merge -- this
changes live lifecycle behavior and has no automated end-to-end coverage.

+"""101 -- add investigation/branch join keys to workflow_state_cursor (RFC-02).
+
+Closes the cursor-keying Class-A defect: cursor rows are keyed by the
+random ARQ task uuid, so the lifecycle service's investigation-scoped
+pause/resume queries matched zero rows and fell through to weaker
+fallbacks. The engine now denormalizes investigation_id + branch_id onto
+each cursor at creation, and the lifecycle service queries by them (with
+the run_id ANY(...) legacy fallback kept for pre-existing rows). Columns
+match WorkflowStateCursor in db_models.py so create_all (tests, fresh
+installs) matches the migrated schema. Both nullable -- existing rows stay
+NULL and the legacy fallback still matches them; non-investigation
+workflows leave both NULL. Guarded with IF NOT EXISTS.

+task uuid (``run_id = task_context.task_id`` at

+resume archival path used to query cursors by

+
+The fix denormalises ``investigation_id`` + ``branch_id`` onto the

+``initial_input`` kwargs). The lifecycle service queries by those
+columns and keeps the ``run_id = ANY(...)`` clause as a legacy fallback
+so pre-migration cursors still resume.
+
+Every test here runs against the create_all-populated ``test_db``
+fixture; no alembic migration needed for the new columns to be visible.

+Live pause / resume on a running investigation is an operator smoke-gate
+at merge -- this pins the unit-level behavior only.

Subject: [PATCH 281/281] docs(changelog): record the leftover RFC increments

Extends the Unreleased entry with the increments completed in the
faithfulness-remediation follow-through: the ResilienceLayer facade
(RFC-07), the eval-gated self-improvement loop (RFC-08), the shadow/canary
lifecycle stages (RFC-10), the generic McpClient with capability dispatch
and pooling (RFC-11), the adaptive retrieval router with stable-core,
graph, result gate, record-replay eval, and ingest enrichment (RFC-12),
and the cursor-keying fix (RFC-02).

+- A single platform `ResilienceLayer` facade over the fail-open sites
+  (classify failure, conservative default with a signal, retry decision),
+  funnelling every fail-closed signal through one
+  `aila_resilience_signals_total` counter (RFC-07).
+- Self-improvement loop behind the eval gate (RFC-08): an ExperienceWriter

+  patterns, a CalibrationProposer that aggregates per-outcome_kind history
+  into a versioned, reversible threshold proposal (migration 097), and a
+  RoutingLearner that publishes a routing recommendation.
+- Shadow and canary lifecycle stages (RFC-10, migration 096): a candidate
+  can be shadowed, canaried to a stable cohort fraction of new
+  investigations by an investigation-id hash, held on a drift or cost
+  spike, then promoted through the eval + quorum gate, all over admin
+  endpoints with no code release.
+- A generic `McpClient` with capability-based server resolution and
+  instance pooling; each MCP tool call records the serving `instance_id`
+  (RFC-11, migration 098). The three bridges keep only their server-
+  specific request/response shaping.
+- Adaptive knowledge retrieval (RFC-12): a router that picks a stable-core
+  (preloaded cache), simple (hybrid), or graph path; a knowledge-entry
+  edge table with bounded multi-hop traversal (migration 100); a
+  sanitize/classify + provenance gate on results; a record-replay

   hardcoded `"vulnerability"` literal even though the module was resolved
