The implementation + plan derived from it covers the OSS half (this repo); the cloud-plugin half is planned + separately in the cloud repo. + +## 1. What and why + +Expose the agentic KV extraction system built in `unstract-agentic-table` (`src/kv`) as a +metered, API-first product on the Unstract platform: upload a document plus a `keys.json` +schema, get a job id, poll a verbose agent-centric status, fetch a rich result (record + +per-field QA/challenger audit trail). Billed per page plus LLM cost via the existing +billing pipeline, with a new Stripe product on the cloud side. + +The engine is proven (QA pass, adversarial challenger, constraint checking, normalizers, +opt-in codegen post-processing). This design is about *hosting* it safely and metering it +— not about changing how it extracts. + +## 2. Locked decisions + +These were settled in the brainstorming discussion and are not open for re-litigation in +the implementation plan: + +| # | Decision | +|---|---| +| D1 | v1 is **KV only**. Table extraction may later ride the same substrate; not now. | +| D2 | The **calculations/codegen path is in scope** for v1 (opt-in per request). | +| D3 | The extraction engine ships as a **cloud executor plugin** (like `agentic_table`), discovered via entry points, invoked through the executor dispatcher. This repo carries the API scaffold, which **fails closed** with a clear error when the plugin is absent. | +| D4 | Public surface is **`POST /agent-kv/`** with `Bearer` key auth, same DX family as existing APIs. | +| D5 | A dedicated **`AgentKVKey`** model; keys are managed in the same area as Platform API key management. Org-scoped, rotatable. | +| D6 | LLM selection is **system-level, env-configured only** (`AGENT_KV_LITE_MODEL`, `AGENT_KV_ADVANCED_MODEL` + provider keys in worker env). No end-user model control. The engine keeps its LiteLLM client. | +| D7 | All engine **caching is account-level** (org-scoped cache keys). | +| D8 | **MCP is parked** for v1. The serializer+helper structure keeps it a cheap bolt-on later. | +| D9 | Codegen executes only in the **dedicated sandbox worker** (§6.3). No in-process execution, no Docker-daemon dependency, anywhere. | +| D10 | Compliance/retention tuning is deferred; **engineering defaults** (config-overridable): uploaded document deleted on job completion; results retained 7 days. | +| D11 | Results are **re-readable until TTL** (deliberate divergence from the one-shot 406 pattern of workflow API deployments), plus explicit `DELETE`. | +| D12 | One document per job in v1. Batch = N calls. | +| D13 | Billing: the platform only **meters** (PageUsage + per-agent Usage rows tagged `product=agent_kv`). Price construction, cache-hit discounts, and failed-job policy are cloud-side policy over meter rows. | + +## 3. Non-goals (v1) + +- Table extraction API (D1). No `json_structure`/table mapping codegen — the KV record + mirrors `keys.json` by construction, so codegen exists only for `calculations`. +- MCP tools (D8), frontend UI, HITL review queue integration, batch endpoints, + per-field live streaming of status, retrieval/RAG, user model selection. +- Compliance-driven retention/residency work (D10). +- Reconciling with the future `agent_kv` Prompt Studio enforce_type — designed *for* + (shared executor, §5.2) but not implemented now. + +## 4. Background: the engine being productized + +`unstract-agentic-table/src/kv` pipeline (stage-sequential): + +``` +document_processor → key_extractor (+ array_extractor) → [kv_qa] → [kv_challenger] + → normalizers → constraints → [code_generator → code_executor] (bracketed = optional) +``` + +- OCR: LLMWhisperer V2 (`mode=form`, layout-preserving, hex line numbers — grounding/QA + depend on them) + pypdfium2 page images (DPI 150). Excel OCR'd text-only. +- LLM: LiteLLM, two tiers (`lite_model`/`advanced_model`), streaming, retry/backoff, + truncation fail-loud, optional forced tool-use. +- Result object: `record`, `normalized_record`, per-field `keys[]` audit trail + (qa_status/attempts, challenge_status/attempts/reason, provenance), `qa_passed`, + `challenge_passed`, `consistency_violations`, `cost_summary` (per-agent tokens+USD), + `timing` (per stage). +- Codegen is gated: `run_codegen = (calculations is not None) and (output_path is not None)` + (`kv_extractor.py:64`).

When the +Prompt Studio `agent_kv` enforce_type is built (by another engineer, near-term), it +dispatches to the **same executor** with a second entry operation. To make that work +without speculative code, the engine takes its LLM configuration via a small injected +config object: env-LiteLLM for this API (D6), adapter-resolved for the enforce_type later +(the pattern `agentic_table` already proved with its `llm_adapter_instance_id` params). + +### 5.3 Async dispatch rules (hard requirements, from UN-3445) + +- Resolve transport **once**, at job creation, via `resolve_transport(entity_id=execution_id)`; + carry it in the payload; never re-resolve mid-flight. +- Celery handle → `task_id` (UUID column); PG handle → `queue_message_id` (bigint column). + Never coerce one into the other. +- Stamp `dispatched_at` positively on successful dispatch; provide a sweep for + create-then-dispatch orphans (the 967-stuck-executions incident applies to any new + async entry path). AgentKVJob gets its own `dispatched_at` + a periodic sweep that + terminalizes never-dispatched jobs. +- Codegen fan-out (executor → sandbox queue) uses `queue_backend.dispatch` with the + execution's resolved backend override. +- Logs go through `LogPublisher` (transport-agnostic). + +### 5.4 Job lifecycle and state + +`AgentKVJob` (new model, this repo): `id` (UUID4), `organization` FK, `api_key` FK, +`status` (PENDING → DISPATCHED → RUNNING → COMPLETED | FAILED | CANCELLED), `stage`, +`stages` (JSONB: per-stage status/timing/counters, written by the executor via the +internal API), `pages_total`, `input_ref` (object-store path), `result_ref`, +`usage_summary` (denormalized cost/tokens snapshot), `error` (user-safe message), +`dispatched_at`, `created_at`, `completed_at`, `expires_at`, `tags`, `custom_data`, +`webhook_url`. + +Documents stage in org-prefixed object-store paths; queue payloads carry references, +never bytes. Results persist to the object store with a DB pointer (not Redis-only), +enabling D11 re-reads and TTL cleanup (a periodic job deletes expired results and any +leftover inputs). + +Stage progress: the executor reports stage transitions through the existing internal API +pattern (workers → `/internal/v1/...`), idempotent upserts (at-least-once delivery). + +## 6. Security model (approved) + +Premise: **the document, `keys.json`, `key_notes`, and `calculations` are all +attacker-controlled**, and they flow into prompts and codegen. Assume a hostile key +holder and a hostile document independently. + +### 6.1 API edge + +- New top-level public prefix; middleware bypass means **views own auth** — documented, + with regression tests that every endpoint 401s without a valid key (MCP test pattern). +- `Bearer `: org-scoped, rotatable, managed alongside platform keys (D5). +- IDOR: job ids are UUID4 **and** every lookup filters by the key's org; unknown and + forbidden both → 404. +- Fail fast before paid work: file-type allowlist (PDF/XLSX/XLS/images), file-size cap, + **local page count via pypdfium2 before OCR** vs. page cap, `keys.json` compile + + structural caps (max leaves, array columns, nesting depth, regex length), max + `calculations` bytes. +- Per-org concurrent-job limit (existing Redis limiter pattern) + per-key rate limit; 429. + +### 6.2 LLM path + +Agents have no tools and no agency: LLM output is parsed into the record, never +executed, never used to call platform APIs, never crosses jobs. Injection therefore +corrupts only the attacker's own result — except two escalation channels, each closed: + +1. **Injection → codegen** (document shapes the record; record + calculations feed the + code generator): all generated code goes through §6.3, no trusted-caller bypass. +2. **Injection → audit trail** (challenger/QA reasons quote document text into status + output): treated as untrusted text wherever rendered. + +### 6.3 Codegen sandbox (normative — D9) + +Five mandatory layers: + +1. Fail-closed AST gate (existing `_check_code_safe`, kept and regression-tested). +2. Subprocess with **scrubbed environment** (empty env, minimal PATH). +3. Hardened pod: `runAsNonRoot`, `readOnlyRootFilesystem` + per-job `emptyDir` tmp, all + capabilities dropped, `seccompProfile: RuntimeDefault`, + `automountServiceAccountToken: false`, CPU/memory/PID limits, wall-clock timeout. +4. NetworkPolicy: default-deny egress except the broker. +5. No secrets in the pod beyond a broker credential scoped to the sandbox queues; the + scrubbed subprocess env hides even that from generated code. + +The sandbox receives only the record JSON + generated code (opaque job ref; no document, +no schema, no tenant identifiers). Output is validated as JSONL and size-capped. +Stdlib-only image (`python:slim`-class, nothing installed). + +It is a plain Deployment consuming a dedicated queue — **no Docker daemon, no +docker.sock, no DinD, no privileged pods, no per-job container spawning**. Compose/dev +runs the same worker as a service on an isolated internal network. The ported engine +**deletes** `CodeExecutor`'s environment-sniffing transport (docker-run vs direct-exec +fallbacks) and replaces it with a `CodeExecutionTransport` interface whose production +implementation is the sandbox queue dispatch. Upgrade paths (not v1): `runtimeClass: +gvisor`; per-job K8s Jobs. + +Open verification (does not block this design): confirm what the production +`agentic_table` executor does with generated table-mapping code today. If it executes +in-process, that is a latent finding there; this sandbox worker is designed to be shared +by both engines and the future enforce_type. + +### 6.4 Workers and data + +- Executor worker holds the system LLM keys: own Deployment + Secret, not shared with + backend or sandbox. +- No document bytes through the broker; org-prefixed object-store staging; deletion on + completion + TTL sweep (D10). +- Log hygiene: no document content or extracted values in logs; debug traces org-scoped, + object-store-persisted, flag-gated. + +### 6.5 Cache isolation (D7) + +Cache key = `org_id + sha256(document) + canonical-hash(keys.json) + engine_version + +model_ids + mode_flags (qa, challenge, extraction_mode, structured_output, page range)`. +Org in the key makes cross-tenant reuse structurally impossible; versions/flags in the +key prevent stale-config replay (the FileHistory lesson). + +### 6.6 Billing integrity + +- Worst-case job spend bounded pre-dispatch (page cap × known pricing); admission gated + by the cloud subscription plugin's reserve/commit/discard protocol — **fail-closed** + (viable because the engine is cloud-only). +- All cost figures measured server-side; nothing cost-related read from the request. +- Alerts: AST-gate rejection spikes, 401 bursts, repeated max-page submissions. + +### 6.7 Inherited test patterns + +Credential-leak test (seed fake secrets, drive every read path, fail on leak); +unauthenticated-access tests per endpoint; AST-gate escape corpus (regression suite, not +a soundness proof — the sandbox carries the real weight). + +## 7.

LLMWhisperer credentials from platform config, not user env. +5. Stage-progress callbacks emitting to the internal status API (§5.4). +6.

Testing strategy + +- **This repo:** serializer/compile validation (including every §6.1 cap), auth tests + (401/404-IDOR/429/keys lifecycle), dispatch tests (transport resolution, dual handle + columns, `dispatched_at`, sweep), result lifecycle (TTL, re-read, delete, 501 + plugin-absent), usage-emission tests against a stubbed platform-service. +- **Cloud repo:** engine golden tests (the existing eval harness carries over), sandbox + integration (AST corpus, scrubbed env, limits, output caps), end-to-end job runs. +- Inherited patterns per §6.7. + +## 11.

Concurrency slot leak: stage_input()/job.save() ran unguarded after check_and_acquire() succeeded, so an object-store or DB error left the slot stuck for up to the 6h TTL and returned an unhandled 500. Now wrapped in try/except: always release the slot, mark_terminal(FAILED) only when the row was actually persisted, and return a safe "Job could not be accepted; nothing was billed." 500. 2. dispatch_job's ExecutionContext construction and the platform-key lookup ran outside its try block, so a raw (non-DispatchError) exception there skipped mark_terminal, slot release, and the safe 500 entirely. Widened dispatch.py's try to cover the full fallible body (frozen executor_params/callback contract unchanged), and added a belt-and-braces except Exception in execution_views.py with identical cleanup to except DispatchError, via a shared _fail_job_response helper. The 300s sync-timeout polling loop (a third review finding) is intentionally untouched per controller ruling.

Auth is ambient (InternalAPIAuthMiddleware); both views take empty auth/permission classes and require org_id in the body (400 without it). StageReportView merges one stage's progress into job.stages, flipping PENDING/DISPATCHED -> RUNNING on first report only. It is the sole write gate for job.stages: only {status, seconds?, ...counters} is persisted, so unexpected top-level body keys never leak into a stored entry (carried constraint from task 9's status-endpoint review). A late report against an already-terminal job is a 200 no-op via the TERMINAL-excluding update queryset. FinalizeView writes the result then calls mark_terminal on success, or calls mark_terminal(FAILED, error=...) on failure; the concurrency slot is always released in a finally. It pre-checks the job's terminal state so a duplicate/late finalize call returns finalized:false without ever rewriting an already-written result. Response is {finalized, webhook_url, status} -- built out now so task 12 doesn't need to reopen this file. 79 previous agent_kv tests + 13 new all pass (80 total).

20:13:16 +0530 Subject: [PATCH 22/98] fix(agent-kv): race-safe stage merge, counters write-gate, malformed-body 400s Controller-authorized fixes from task-11 review (3 Important issues): 1. Stage-merge lost-update race: replace the Python read-modify-write (dict(job.stages or {}) -> merge -> full-column .update(stages=...)) with a DB-side jsonb `||` concatenation expression (_stage_merge_expression), so .update() only ever merges the reported stage's single-entry dict at the database level. Two concurrent reports for different stages can no longer clobber each other. The earlier read is kept only for the RUNNING-flip decision and the terminal no-op check, both re-guarded at update time by job_qs's existing TERMINAL exclusion. 2. counters bypassing the write gate: add _sanitize_counters(), which drops any counter key colliding with the reserved {"status", "seconds"} fields and any non-scalar (dict/list) value, before merging into the stage entry. Closes the task-9-review write-gate constraint against counters clobbering reserved fields or admitting nested structures. 3. Malformed bodies: StageReportView now 400s on missing `stage` or a `status` that isn't exactly "running"/"done"; FinalizeView now 400s unless `success` is a strict bool (isinstance check, not truthy/ falsy) -- a malformed finalize call no longer silently persists a FAILED job with an empty error. Both 400 paths return before the concurrency slot could be touched, so no release() call happens on them (nothing was finalized). test_internal_views.py: 13 -> 23 tests (10 new: expression-builder unit tests, counters-sanitization tests, and the three new 400 cases). 90 passed in agent_kv/tests/ (67 pre-existing outside this file + 23 here).

The document, `keys.json` schema, +and OCR/LLM extraction pipeline itself are described only insofar as they shape the +contract; the extraction engine ships as a cloud executor plugin (see +[§11, 501 behavior](#11-when-the-engine-is-unavailable-501-behavior) below). + +Design background: `docs/superpowers/specs/2026-08-28-agent-kv-api-design.md` (referred +to as "the spec" throughout this document; section numbers below are spec section +numbers). This document records what shipped, including a handful of places where the +implementation is more specific than — or diverges from — the spec's sketch. Those are +called out explicitly rather than silently reconciled. + +## 1. Authentication + +There are two independent auth schemes on two different URL prefixes: + +| Surface | Prefix | Auth | +|---|---|---| +| Public execution API (submit/status/result/cancel/validate) | `/agent-kv/…` (top-level, not under the tenant subfolder) | `Authorization: Bearer ` — a dedicated per-organization key, validated by the view itself | +| Key management (create/list/rotate/revoke) | `{PATH_PREFIX}/unstract/…/agent-kv/keys/…` (tenant-scoped, alongside Platform API key management) | Session auth, `IsOrganizationAdmin` only | + +The execution prefix (`AGENT_KV_PATH_PREFIX`, default `agent-kv`) sits **outside** the +tenant-subfolder/organization-middleware chain — it is added to `WHITELISTED_PATHS` in +`backend/backend/settings/base.py` — because a caller authenticates with an API key, not +a session/org header. Every view under it therefore owns its own auth via the +`AgentKVKeyValidator.validate_api_key` decorator (`backend/agent_kv/key_validator.py`), +which: + +1. Requires `Authorization: Bearer ` where `` is a UUID. +2. Looks up an active (`is_active=True`) `AgentKVKey` by that UUID. +3. Injects the resolved key object as `agent_kv_key` into the view kwargs, which every + subsequent lookup filters by (`organization_id=agent_kv_key.organization_id`) — this + is what makes a job in another org indistinguishable from an unknown job id (both + 404, see [Status](#4-status--get-agent-kvjob_id)). + +**Drift from the spec:** spec §6.1 describes this as "every endpoint 401s without a +valid key." The implementation returns **403** (`api_v2.exceptions.Forbidden`, reused +as-is rather than adding a new exception class) for both a missing/malformed +`Authorization` header and an unknown/inactive key. This is exercised directly by +`backend/agent_kv/tests/test_auth.py` and `test_job_views.py::test_all_job_views_401_without_key` +(the test name predates the code's actual status; both assert `403`). Document the code: +**403, not 401**, for any auth failure on the public prefix. + +Key management (`backend/agent_kv/views.py`, `AgentKVKeyViewSet`) is a standard DRF +`ModelViewSet` scoped by the global `OrganizationFilterBackend` and gated by +`IsOrganizationAdmin` (`backend/agent_kv/permissions.py`). Fields returned: +`id, name, description, key, is_active, created_at`; write-side fields are +`name, description, is_active` only (`key` and `id` are server-generated). Routes +(`backend/agent_kv/urls.py`, mounted at `agent-kv/` under +`backend/backend/urls_v2.py`): + +``` +GET/POST .../agent-kv/keys/ +GET/PATCH/DELETE .../agent-kv/keys// +POST .../agent-kv/keys//rotate/ # replaces `key` with a new UUID +``` + +Key storage follows the same conventions as Platform API key management (D5) — +plaintext-at-rest UUID keys, not hashed-at-rest; that hardening is explicitly deferred, +not a v1 gap unique to this feature. + +## 2. The extraction schema (`keys` field) + +The `keys` submit field — spec-called "keys.json" — is a JSON object describing what to +extract. It compiles through `unstract.agent_kv_schema.compile_schema` +(`unstract/agent-kv-schema/src/unstract/agent_kv_schema/`), the **single schema compiler +in the system**: the OSS API validates with it at submit time and at `/validate`, and +the cloud engine imports the same package to execute — the schema language cannot drift +between validation and execution by construction (spec §5.1). + +### Node types + +A schema node is one of three shapes, decided structurally: + +- **Interior node** — every value is itself an object → its keys are child nodes, and + nesting continues (dotted path, e.g. `vendor.address.city`). +- **Leaf node** — no value is an object → defined by scalar attributes: + + | Attribute | Required | Meaning | + |---|---|---| + | `description` | **yes** | Prompted to the extractor; also fed to the breadcrumb-prefixed `effective_description`. | + | `format` | no (default `string`) | `string` \| `number` \| `currency` \| `date` \| `enum:v1,v2,…` \| `regex:` \| any other free-text hint. `number`/`currency` parse via a strip-then-`float()` check; `date` accepts a fixed set of common formats; `enum` matches case-insensitively; `regex` is `re.fullmatch`. | + | `required` | no (default `false`) | Completeness is checked separately from format. | + | `aliases` | no (default `[]`) | Alternate names/labels to help the extractor recognize the field. | + | `multivalued` | no (default `false`) | Value is a comma-separated string; each element is format-checked independently. | + + A node mixing object values and scalar attributes is a **compile-time error** + ("mixes object children and scalar attributes"), as is a leaf with unknown attribute + keys or a missing `description`. + +- **Array node** — has an `_array` key → a flat (non-nested) row schema: + + ```json + "line_items": { + "description": "One row per invoice line", + "_key": "sku", + "_array": { + "sku": {"description": "SKU"}, + "total": {"description": "Line total", "format": "currency"} + } + } + ``` + + `_array`'s value is itself a flat object of leaf columns (row-local paths, not + dotted). `description` is optional context; `_key` (optional) names a column used for + row identity in downstream scoring, otherwise rows are matched positionally. A + nested array inside an array's row schema is rejected at compile time ("not supported + in P8a") — arrays are single-level only in v1. + +### Constraints (`_constraints`) + +An optional top-level `_constraints` key: a list of string expressions checked against +the extracted record post-hoc. Each expression is parsed and statically validated +against an AST allowlist before it is ever accepted — no arbitrary code execution: +boolean/comparison/arithmetic operators, plus exactly one string-literal argument to one +of `sum`, `count`, `min`, `max`, `avg` (an array path). Example: +`"count('line_items') >= 1"`. + +### Structural caps (spec §6.1) + +Enforced by `compile_schema` regardless of the byte-size cap below (`SchemaCaps` in +`compile.py`): + +| Cap | Default | +|---|---| +| Max leaves | 200 | +| Max arrays | 20 | +| Max columns per array | 40 | +| Max nesting depth | 6 | +| Max regex pattern length | 200 | +| Max aliases per field | 10 | +| Max description length | 500 | +| Max constraints | 30 | + +These caps are hardcoded in the compiler (not env-configurable); what **is** +env-configurable is the raw byte size of the whole `keys` document +(`AGENT_KV_MAX_SCHEMA_BYTES`) and of `calculations` +(`AGENT_KV_MAX_CALCULATIONS_BYTES`) — see [§13 env reference](#13-environment-reference). + +A schema that fails to compile is rejected with a `400` at submit time — **nothing is +billed** — or, at `/validate`, with a `200` carrying `{"valid": false, "error": ""}` +(compile errors are not 400s there; only a missing `keys` body key is). + +## 3.

When the engine is unavailable (501 behavior) + +The Django backend cannot see the executor plugin registry (that lives in the workers +process). Dispatching to a queue no worker consumes would hang, not error — so gating +happens **before enqueue, in the backend**, via a capability probe: + +```python +if not get_plugin("agent_kv"): + raise EngineUnavailable() # 501, "agent-kv engine not available on this deployment" +``` + +`get_plugin(...)` (`backend/plugins/__init__.py`) returns an empty dict — falsy — when +no `plugins/agent_kv/` package is installed, which is the OSS-only case by design (the +plugin is a cloud deliverable, spec §5.1/§11: "OSS scaffold merges dark"). Every +`POST /agent-kv/` on an OSS-only deployment therefore returns: + +```json +{"detail": "agent-kv engine not available on this deployment"} +``` + +with HTTP `501`. `/validate`, key management, status/result/cancel/delete on +*already-existing* jobs are unaffected by this gate — only `SubmitView` probes it, +since only submit needs the engine. + +## 12. Deploy checklist + +Everything below is required (or worth checking) to run this feature for real, +beyond `docker compose up`: + +1. **Cloud plugin**: install/enable the `agent_kv` backend capability plugin + (probed via `plugins.get_plugin("agent_kv")`) — without it, submit always 501s + ([§11](#11-when-the-engine-is-unavailable-501-behavior)). This repo ships gated + dark by design; nothing to do for an OSS-only deployment except accept the 501. +2. **Executor worker fleet queue**: the executor dispatch derives its Celery queue name + from the executor name as `celery_executor_{executor_name}` — for Agent-KV that's + **`celery_executor_agentic_kv`** (`unstract/sdk1/src/unstract/sdk1/execution/dispatcher.py`). + `workers/run-worker.sh`'s executor role default queue list + (`celery_executor_legacy,celery_executor_agentic,celery_executor_agentic_table`) + does **not** include it yet — a deployment running the cloud `agentic_kv` executor + plugin must add `celery_executor_agentic_kv` to that worker's consumed queues + (`CELERY_QUEUES_EXECUTOR` on the Docker path, or the equivalent `run-worker.sh` + queue map entry) or dispatched jobs will never be picked up. +3. **Callback queue**: the `ide_callback` worker must consume `agent_kv_callback` + alongside its own `ide_callback` queue, or jobs dispatch but never finalize. This is + already the hardcoded default in both `workers/run-worker-docker.sh` and + `workers/run-worker.sh` (`WORKER_QUEUES["ide_callback"] = "ide_callback,agent_kv_callback"`) + — nothing to configure for a standard deployment; see the note already in + `docker/sample.env` under "IDE Callback Worker." +4. **Internal periodic maintenance — not wired up yet.** Two internal endpoints exist + and are fully functional (`backend/agent_kv/internal_urls.py`, + `internal_views.py::SweepView`/`TTLCleanupView`) but **nothing currently calls them + on a schedule** — there is no PG-scheduler/Beat registration for either, unlike the + dashboard-metrics periodics (`workers/scheduler/dashboard_metrics_tasks.py`), which + this feature was designed to follow (spec §5.4). A production deployment must + register both as periodic tasks before relying on TTL cleanup or stuck-job recovery: + - `POST /internal/v1/agent-kv/sweep/` — terminalizes `PENDING` jobs never dispatched + within `AGENT_KV_SWEEP_GRACE_SECONDS` (default 1 hour). Suggested cadence: every + few minutes. + - `POST /internal/v1/agent-kv/ttl-cleanup/` — deletes staged input/result files past + `expires_at`. Suggested cadence: hourly or daily (retention is measured in days). + Both are idempotent, batch-capped at 500 rows per call, and safe to call more often + than needed. +5. **Env vars**: every `AGENT_KV_*` setting plus `AGENT_KV_FILE_STORAGE_CREDENTIALS` — + see [§13](#13-environment-reference) and `docker/sample.env`. +6. **Object storage**: `AGENT_KV_FILE_STORAGE_CREDENTIALS` must point at a real bucket + in production (defaults to the same shared MinIO instance as workflow execution). + Paths are org-prefixed (`org/{org_id}/agent_kv/{job_id}/input{ext}`, + `.../result.json`) — no document bytes ever ride the message broker. + +## 13.

From ab1739b6f4b10c45fee65cb2cc2f3f00ae4aa007 Mon Sep 17 00:00:00 2001 From: Arun Venkataswamy <5359196+arunvenkataswamy@users.noreply.github.com> Date: Fri, 28 Aug 2026 21:52:29 +0530 Subject: [PATCH 31/98] fix(agent-kv): delete staged input when finalize terminalizes a job (spec D10) Controller-authorized fix for a cross-task spec gap found during the docs task (Task 15): spec D10 says "uploaded document deleted on job completion," but nothing deleted the staged input -- it rode TTL cleanup like the result. - backend/agent_kv/storage.py: add delete_input(job), a narrower sibling of delete_job_files that removes only input_ref (never result_ref), tolerant of an already-missing file. - backend/agent_kv/internal_views.py (FinalizeView): when mark_terminal wins (job just became COMPLETED or FAILED), call delete_input(job) and blank input_ref via a targeted single-row update. Never runs on the duplicate/guard-lost path. Cancelled jobs are excluded by construction -- cancel goes through JobCancelView/mark_terminal directly, not FinalizeView -- documented with a comment at the call site. - docs/agent-kv-api.md Sec 10: replace the "input persists until TTL, drift from D10" flag with the now-true behavior (input deleted at finalize; cancelled jobs' input still rides TTL). Also touched two directly-adjacent mentions (the AGENT_KV_RESULT_TTL_DAYS table row and the storage-helper list) for consistency. - Tests: 3 new in test_internal_views.py (success/failure delete+blank, duplicate does NOT call delete_input) + 3 new direct unit tests for storage.delete_input in test_storage.py. agent_kv/tests/test_internal_views.py: 23 -> 26 passed. agent_kv/tests/: 107 passed (includes Sweep/TTLCleanup/docs work from Tasks 12-15 that landed on this branch since the prior fix pass).

From 79a94fd1ad9ae69237dfc56b456267239a40e654 Mon Sep 17 00:00:00 2001 From: Arun Venkataswamy <5359196+arunvenkataswamy@users.noreply.github.com> Date: Fri, 28 Aug 2026 22:28:20 +0530 Subject: [PATCH 32/98] =?UTF-8?q?fix(agent-kv):=20final-review=20fixes=20?= =?UTF-8?q?=E2=80=94=20guarded=20dispatch=20stamp,=20orphan=20cleanup,=20c?= =?UTF-8?q?ap=20semantics,=20cancel-on-delete,=20stuck-job=20sweep,=20sche?= =?UTF-8?q?duler=20wrappers,=20doc=20corrections?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Fix 1: dispatch.py post-enqueue bookkeeping is now a guarded queryset update (WHERE status=PENDING) instead of a plain job.save(), so it can never overwrite a status the job already raced to (e.g. instant executor failure finalizing before this write lands). - Fix 2: FinalizeView deletes the just-written result file (storage.delete_result_file) when the terminal-state guard is lost right after a successful write, closing an orphaned-file leak. - Fix 3: dispatch executor_params now sends max_pages as the configured cap (AGENT_KV_MAX_PAGES) instead of the measured pages_total (None for Excel), with pages_total riding along as its own field. - Fix 4: docs/agent-kv-api.md documents the cancel-at-pickup contract explicitly (StageReportView's noop:true is the drop signal; the executor must still call finalize so the concurrency slot gets released). - Fix 5: new workers/scheduler/agent_kv_tasks.py (agent_kv_sweep, agent_kv_ttl_cleanup) calling two new InternalAPIClient methods, wired into workers/scheduler/tasks.py the same way as dashboard_metrics_tasks. - Fix 6: docs/agent-kv-api.md's webhook SSRF section rewritten to match send_webhook's real behavior (resolution-time check only, DNS-rebinding TOCTOU accepted for v1, https-only in practice, no retries). - Fix 7: DELETE on a non-terminal job now cancels it (mark_terminal) before deleting files, so a late finalize can't resurrect a deleted result. - Fix 8: SweepView gained a second phase that force-fails DISPATCHED/RUNNING jobs stuck past AGENT_KV_STUCK_JOB_GRACE_SECONDS (new setting, default 6h), releasing their concurrency slots; response is now {swept, timed_out}. - Courtesy: backend/sample.env gained the AGENT_KV_* block mirroring docker/sample.env. Tests: 120 backend agent_kv tests + 53 workers tests (scheduler wrappers, dashboard_metrics regression, worker task import mechanisms, ide_callback agent-kv callbacks, webhook_notify) all pass. ruff check clean on every file touched by this commit.

Aug 2026 11:46:27 +0530 Subject: [PATCH 35/98] feat(agent-kv): management commands for sweep and TTL cleanup Move SweepView.post/TTLCleanupView.post bodies verbatim into agent_kv/maintenance.py as run_sweep()/run_ttl_cleanup(), leaving the views as thin wrappers. Add agent_kv_sweep and agent_kv_ttl_cleanup Django management commands wrapping the same functions so Kubernetes CronJobs can drive the maintenance logic in the cloud deployment, alongside the existing scheduler-task mechanism for OSS/self-hosted. test_sweeps.py stays green with import-path-only adjustments: patches on delete_job_files/timezone.now/timedelta now target the maintenance module (where the real work now happens) instead of internal_views. Adds test_maintenance_commands.py pinning the command<->function wiring. docs/agent-kv-api.md's periodics section now documents the CronJob mechanism alongside the scheduler wrappers.

The executor fleet is not a FILE_PROCESSING worker: WorkerConfig._get_worker_specific_timeout_defaults() falls through to the "other workers" branch for WorkerType.EXECUTOR, i.e. 3,600s hard / 3,300s soft — and the chart's bare TASK_TIME_LIMIT ConfigMap key is inert (get_celery_setting only reads EXECUTOR_TASK_TIME_LIMIT or CELERY_TASK_TIME_LIMIT), per the comment already on workerExecutorV2's terminationGracePeriodSeconds in charts/unstract-platform/values.yaml. Rewrote item 8: the real baseline (3,600s) and the actual lever (EXECUTOR_TASK_TIME_LIMIT, noting TASK_TIME_LIMIT is inert); the 7,425s worst-case gap against that baseline is 3,825s, not 225s, and that figure assumes every one of 300 calls hits the full 8-retry backoff -- unrealistic, real calls run ~10-30s so a capped run is closer to ~2,000-2,500s in practice; and a revised recommendation to measure real per-page timing before raising the fleet-wide limit (which is shared across every executor plugin and coupled to workerPgExecutor's PG lease and terminationGracePeriodSeconds) rather than raising it preemptively.

Module self-gates on UNSTRACT_BACKEND_URL + AGENT_KV_E2E=1 so it never runs under a plain OSS e2e sweep (the lane needs the cloud agentic_kv executor plugin, which OSS doesn't ship); a narrower require_llm fixture gates only the two scenarios that need a job to actually reach COMPLETED. fixtures/invoice.pdf is a generated (reportlab, one-off, not an e2e-venv dependency), OCR-able 2-page fixture -- the existing backend/agent_kv/tests/fixtures/two_page.pdf has no extractable text and can't serve as an extraction fixture. - tests/groups.yaml: e2e-agent-kv group, optional: true (so an OSS-only CI run doesn't go red for a plugin it doesn't ship), depends_on: [e2e-smoke]. - tests/compose/docker-compose.test.yaml: backend gets a pass-through AGENT_KV_MAX_PAGES override (page-cap scenario); worker-executor-v2 gets celery_executor_agentic_kv added to its queue set (as a superset of the existing default, not a replacement -- other e2e lanes' tools still dispatch through celery_executor_agentic/_agentic_table on this same worker) plus the AGENT_KV_LLM_*/LLMWHISPERER_* pass-throughs. - workers/sample.env: added AGENT_KV_FILE_STORAGE_CREDENTIALS alongside its two siblings (WORKFLOW_EXECUTION_/API_ FILE_STORAGE_CREDENTIALS) -- that's the actual mechanism those use to reach worker-executor-v2 (env_file, not a compose-level override), mirrored here rather than inventing a new one. Verified without Docker: pytest collection (module skip fires correctly, and all 8 tests collect cleanly with the gate env set), `tests.rig validate` and `expand e2e-agent-kv`, ruff, and `docker compose ... config` against the merged base+overlay file (using a newer standalone Compose binary fetched for this session, since the sandboxed Docker CLI's bundled Compose plugin predates the `include:` directive the base compose file already relies on) -- confirmed the new env resolves correctly on both services, including override pass-through.

A caller creating a key had no other way to learn the secret they just created. - backend/agent_kv/tests/test_key_management.py: new test_create_returns_id_and_key, stubbing AgentKVKeyWriteSerializer.save directly (ModelSerializer.save()'s create path resolves AgentKVKey._default_manager, not whatever AgentKVKey.objects is patched to at runtime, so the file's usual objects-mock pattern would silently fall through to a real DB call here). - tests/e2e/agent_kv/test_agent_kv_e2e.py: test_concurrency_limit_returns_429 moved to run last in the module (JobCancelView never releases a concurrency slot -- only a job's own finalize call does, so this deliberately-saturating scenario could otherwise 429 sibling submit-based tests); its finally now cancels the accepted jobs (courtesy only) then bounded-drains (<=120s) by re-probing submit until a 202 proves a slot freed, instead of assuming cancel itself released anything; the batch assertion now requires every status in {202, 429}, not just "429 present". - tests/groups.yaml: e2e-agent-kv gets parallel: false, so xdist can never interleave the concurrency scenario's saturation with a sibling test in the same run regardless of source order. Re-verified: backend/agent_kv/tests full suite (127 passed), e2e module collection with the gate env set (8 tests, concurrency last), rig validate, ruff.

Adds that caveat and the "agents omitted on a full cache hit" note. docs §12.5: the strict per-environment rollout order for the agentKv chart group (GSM secrets -> the three non-secret keys in that env's values -> roll out) and the blast radius, since both executor fleets mount the group with envFrom and sit in CreateContainerConfigError until the Secret exists. Under ESO a nil non-secret key is silently dropped from the ExternalSecret template. docs §12.8: what actually happens at each executor time limit -- the soft limit now stops LLM retries promptly and finalizes "timed out" with usage flushed, while a hard-limit SIGKILL still drops in-memory usage records (LLM spend unmetered). e2e: test_bad_llm_key_ends_failed (operator-gated on AGENT_KV_E2E_BAD_KEY_JOB=1; the only scenario covering the terminal FAILED path, asserting the error is user-safe rather than a path/provider body), test_resubmit_same_document_hits_ document_cache (second job's document_processing < 1.0s), and a bounded slot-release probe after the cancel scenario. The concurrency scenario's inlined drain loop is now a shared _drain_until_slot_free helper.

F6 (Critical) — dispatch resolved the platform key by the org row PK. `dispatch._platform_api_key` passed `str(job.organization_id)` (the row UUID) to `PlatformAuthenticationService.get_active_platform_key`, which resolves its argument as the org's public *slug* (`Organization.organization_id`) — so every dispatch died with `ActiveKeyNotFound` (500 "Job could not be dispatched"). It now takes the job and reads `job.organization.organization_id`; the regression test pins the slug and keeps `ctx.organization_id` on the PK. F1 (Critical) — object-store root had no bucket. `storage._base` built `org/{org_id}/agent_kv/{job_id}/...`; s3fs/gcsfs read the first path segment as the bucket, so every submit failed `NoSuchBucket` (500, nothing billed). Adds `AGENT_KV_STORAGE_DIR_PREFIX` (default `unstract/agent_kv`, trailing `/` stripped) alongside the other AGENT_KV_* settings, mirroring `WORKFLOW_EXECUTION_DIR_PREFIX`/`API_EXECUTION_DIR_PREFIX`, and reroots paths to `{prefix}/{org_id}/{job_id}/input{ext}` | `.../result.json`. The variable is the shared contract with the cloud executor plugin, which reads the same name and keys its OCR cache under `{prefix}/{org_id}/cache/`. Wired through backend/docker/workers sample.env and both `backend` and `worker-executor-v2` in tests/compose/docker-compose.test.yaml; storage tests updated plus two new ones (configured prefix is honoured; the shipped default is bucket-rooted). F2 (Important) — the e2e lane asserted the OSS error envelope. Under the cloud backend a 400 is drf-standardized-errors (`{"type":"validation_error","errors":[{"attr":"file",...}]}`), not `{"file": [...]}`. Adds `_validation_error_attrs()` reading both shapes, used by the unreadable-PDF and page-cap scenarios. The validate scenario needs no shim (its 200 body is the view's own result payload, not an error envelope) — noted in place. F9 (Important) — the happy-path e2e read `keys[].path`; the engine and API emit `keys[].key_path`. Test fixed, and docs §5's result example corrected, with the real live entry's field set documented. F3 (Minor) — tox.ini `passenv` forwarded only `UNSTRACT_*`/`VERSION`, so `AGENT_KV_*` never reached compose under tox and the e2e lane ran misconfigured. `AGENT_KV_*` added. F4 (Minor) — `tests.rig run` sets `UNSTRACT_LLM_MOCK_RESPONSE=MOCK_LLM_OK` whenever a group needs the platform (an exported empty value counts as unset), so a real-key Agent-KV run cannot go through the rig. Documented in docs/agent-kv-api.md §12: boot the stack (`tests.rig platform up` or compose) and invoke `pytest tests/e2e/agent_kv` directly. Docs: storage path contract updated in docs/agent-kv-api.md (§5, §12 checklist — new prefix/bucket item, §13 env reference) and the spec §5.4.

Status: approved design (brainstormed with Arun; approach and all +sections approved in chat). Parent: `2026-08-28-agent-kv-api-design.md` §6.3 (normative +security model, D9) and the cloud executor design (`unstract-cloud` +`docs/superpowers/specs/2026-08-29-agent-kv-cloud-executor-design.md`, seam C-series). + +## 1. Goal and scope (S1) + +Ship the dedicated hardened sandbox worker that executes engine-generated calculation +code, and take the API's `calculations` field to **GA in one cycle**: +`AGENT_KV_CALCULATIONS_ENABLED=true` at the end, proven by live e2e. Explicitly out of +scope (follow-ups): migrating `agentic_table` onto this sandbox (verified 2026-09-01: +it currently executes generated code **in-process via subprocess** in the worker pod — +the latent finding §6.3 anticipated; the interface here is built to serve it), the +Prompt Studio enforce_type, gVisor/`runtimeClass`, per-job K8s Jobs. + +## 2. Placement (S2) + +The sandbox worker is **OSS** (`Zipstack/unstract`, branch `Feat/agent-kv-api`): +generic infrastructure — a hardened queue consumer that runs stdlib-only Python against +JSON — usable by OSS deployments and tested by the OSS rig. The cloud half shrinks to +the `SandboxCodeTransport` in the `agentic_kv` plugin + chart wiring + the flag flip +(new Jira ticket, to be assigned). + +## 3. Transport mechanism (S3) + +Request-reply over the **existing executor-RPC machinery** +(`unstract.workflow_execution.executor_rpc`: `PgExecutionDispatcher` — unique +`reply_key`, poll `pg_task_result`, timeout, at-least-once + caller-timeout — with +`RoutingExecutionDispatcher` falling back to Celery), on a dedicated queue. Rejected: +Celery-only `AsyncResult.get()` (breaks in PG-queue mode — the mode cloud runs; known +deadlock foot-gun) and an HTTP microservice (violates §6.3's broker-only egress; +new in-cluster auth surface). + +## 4. Task contract (S4) + +One task, `execute_sandboxed_code`, queue `sandbox_codegen` (+ PG twin per the +`workerPg*` conventions). Request — every cap re-enforced server-side regardless of +what the caller sent: + +```json +{ + "request_id": "", + "code": "", + "input_json": "", + "timeout": 30 +} +``` + +Reply: `{"success": bool, "rows_jsonl": "", "rows_written": int, "stdout": "<4 KiB trunc>", "stderr": "<4 KiB trunc>", +"error": ""}`. + +Inline payloads keep object storage entirely out of the sandbox's reach: it sees only +record + code — never the document, the schema, or tenant identity. At-least-once +redelivery is safe: the code is a pure transform (no side effects to duplicate). + +## 5. The worker (S5) — `workers/sandbox/` + +`WorkerType.SANDBOX`, built like `ide_callback` (`worker.py` via `WorkerBuilder`, +`tasks.py` with the single task), plus `runner.py`, the hardened harness enforcing +§6.3's layers **server-side**: + +1. **AST gate** — the **normative copy lives in the worker**; the engine's + `_check_code_safe` stays as client-side pre-flight, with cross-reference comments + both ways (S6: deliberate duplication of a small security control; the sandbox + never trusts the client's check). +2. **Scrubbed subprocess** — per-request tempdir; `sys.executable -I -S -E` with an + **empty environment** (minimal PATH), cwd = tempdir, `start_new_session`; + `preexec_fn` sets rlimits: CPU (= timeout), address space + (`SANDBOX_MEMORY_MB`, 512 default), NPROC (small), NOFILE, FSIZE (= output cap). + Process group killed at wall-clock `timeout + grace`. The runner stub is **the same + stub contract the engine's `CodeExecutor` uses today** — codegen prompts do not + change. +3. **Output discipline** — JSONL validated line-by-line (`json.loads` each line), + row- and byte-capped, returned inline. Errors are mapped to user-safe strings + (class + stage; no paths, no env, no raw stderr beyond the truncated field). + +Config env (all `SANDBOX_*`): `MAX_CODE_BYTES`, `MAX_INPUT_BYTES`, +`MAX_OUTPUT_BYTES`, `MAX_ROWS`, `TIMEOUT_MAX` (server clamp), `MEMORY_MB`, +concurrency. Registered in `worker_enums_base` / `registry.py` (queue + task route), +`workers/sample.env`, dev compose, and the rig. + +## 6. Image (S7 — amended 2026-09-01, approved by Arun) + +v1 runs the sandbox worker from the **existing `worker-unified` image** (command +`sandbox`), like every other worker: the `workers` package (queue consumers, +`WorkerBuilder`) depends on SDK1/connectors/core, so a truly minimal image requires a +disentangled standalone mini-worker — deferred. The guarantees that matter do not +depend on image contents: the generated-code subprocess runs with a scrubbed empty +env; the pod mounts **no secrets beyond the broker/DB credential** (no `agentKv`, no +`storage` groups); egress is default-denied. A dedicated python-slim image (no SDK1, +no LLM libraries, no platform clients) moves to the **upgrade path** alongside +gVisor/`runtimeClass` and per-job K8s Jobs. + +## 7. Cloud transport + result surfacing + GA (S8, S9) + +`SandboxCodeTransport(CodeExecutionTransport)` in `workers/plugins/agentic_kv/` +(cloud): builds the payload, dispatches request-reply via the routing dispatcher, +writes returned rows to the local `output_jsonl_path`, maps failure to the +`ExecutionResult`-shaped duck object. Timeout / queue unconfigured → +`CodeExecutionUnavailable` → the existing user-safe stage-error path. +`UnavailableCodeTransport` remains the fail-closed default whenever +`SANDBOX_CODEGEN_QUEUE` (default `sandbox_codegen`) is unset/disabled. + +The executor stops passing `calculations=None`: it forwards the submitted +`calculations` and a per-job tmp `output_path` into `KVExtractor` (`run_codegen` +activates), and after the run reads the JSONL back and embeds it in the stored result +as `calculation_rows` (size-capped), alongside the engine's existing +`calculations_applied` / `execution{success, rows_written, error}` / +`codegen_validation_passed` fields (kv_extractor result contract, verified). A failed +execution already fails the job user-safely (`out["success"]=False`). + +GA flip (S9): backend `AGENT_KV_CALCULATIONS_ENABLED=true` in cloud values + test +compose; the serializer un-gates the field; docs §3/§5/§12 updated. The frozen +OSS↔cloud `executor_params` contract already carries `options.calculations` — no +contract change. + +## 8. Hardening (chart) (S10) + +New `sandbox` Deployment: `runAsNonRoot`, `readOnlyRootFilesystem` + sized `emptyDir` +at `/tmp` (256 Mi default), all capabilities dropped, `seccompProfile: +RuntimeDefault`, `automountServiceAccountToken: false`, CPU/memory/ephemeral-storage +limits, replicas/HPA values. Dedicated **NetworkPolicy**: default-deny ingress+egress; +egress only to broker (RabbitMQ), Postgres (PG twin + result rows), DNS. No MinIO/GCS, +no platform-service, no backend, no internet. Secrets: only the broker/DB credential +(own Secret) — none of the `agentKv` or `storage` groups (negative helm-unittest +assertions, mutation-checked). Compose/dev mirrors what it can (`read_only`, +`cap_drop: ALL`, `no-new-privileges`, tmpfs `/tmp`, internal network only). + +## 9. Testing (S11) + +- Worker unit: AST-gate adversarial corpus (`os`/`subprocess`/`socket`/`ctypes` + imports, `eval`/`exec`/`__import__`, encoded payloads); harness hostile-behavior + suite — infinite loop (wall-clock kill), memory balloon (rlimit), fork attempt + (NPROC), oversized output (FSIZE + truncation), stdout flooding, non-JSON output; + happy transform; empty-subprocess-env assertion. +- Cloud transport unit: payload/caps, timeout → `CodeExecutionUnavailable`, + rows written back, error mapping. +- Integration: rig group running the real harness (real subprocesses; no broker). +- e2e (Agent-KV lane): a gated `calculations` happy-path scenario (simple arithmetic + over the invoice; asserts `COMPLETED`, `calculations_applied`, `execution.success`, + computed `calculation_rows`) and a hostile-calculation scenario (job fails + user-safely; no path/env leakage). Both proven in a live "13c" run at the end, + 13b-style. + +## 10. Rollout (S12) + +OSS first (worker + image + compose + rig + docs, on `Feat/agent-kv-api`), then cloud +(transport, chart, flag) under the new ticket.
