From d1edd79a7d79e8230657dd17472f924012ab0a62 Mon Sep 17 00:00:00 2001 From: Eldon Marks Date: Tue, 26 May 2026 11:53:19 -0400 Subject: [PATCH 01/64] feat(db): add PostgreSQL backend with serverless-tuned pooling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PostgresDB joins JsonDB/SQLite/MongoDB/DynamoDB as a first-class backend. Targets Neon, Aurora Serverless v2, and self-hosted PG 15+. - jvspatial/db/postgres.py — asyncpg pool with auto-tuned sizing (Lambda: 0/3, long-running: 2/10), session/transaction pooler modes, schema-scoped tables, JSONB storage, vector column support, native $near peeling, multi-tenant RLS via current_tenant contextvar, transactional save/get/find/delete via PostgresTransaction, and drop_deprecated_indexes for migrations. - jvspatial/db/_postgres_translate.py — Mongo-style query → SQL translator with positional-placeholder builder. - jvspatial/db/factory.py — register "postgres"/"postgresql" with env-driven defaults (DSN, pool sizes, pooler mode). - jvspatial/db/transaction.py — backend-agnostic transaction_context. - docker/ — local dev pgvector container + .env example. - docs/md/postgres-guide.md, neon-deployment.md, aurora-serverless-deployment.md, multi-tenant-rls.md, cursor-pagination.md, schema-migrations.md, vector-store.md. - tests/db/test_postgres_{unit,integration,translate}.py, tests/db/test_cursor_pagination.py. Companion changes pulled in: - jvspatial/core/migrations.py + tests — record-level schema migrations. - jvspatial/core/validate.py + tests — graph-shape validation. - jvspatial/core/entities/walker_components/trail_store.py + tests — pluggable walker trail persistence. - jvspatial/api/auth/_session_store.py + tests — pluggable auth session store (in-process / Redis) for multi-worker deployments. - jvspatial/observability/tracing.py + tests — OTel span helpers. - jvspatial/cli.py — `jvspatial migrate` CLI.

Yields records one at a time; fetches in pages of `batch_size` (default 100). Default base-class implementation uses keyset pagination on `id` (always-unique, lexically sortable per SPEC §1.1) so every backend gets correct constant-memory iteration with no override required. Opaque `cursor` bytes (`base64(json(payload))`) for resume across processes; helpers `encode_cursor()` / `decode_cursor()` exposed on the module. +- **PostgreSQL native `find_iter`** (`jvspatial/db/postgres.py`): single pool connection held for the iteration; one SQL `SELECT ... WHERE id > $last_id ORDER BY id LIMIT $batch_size` per page; composes with the user query so GIN / functional indexes still apply. `sort` argument composes as `ORDER BY , id ASC` for stable keyset tiebreaking. Falls back to base default when the query / sort can't push down. +- **`Object.find_iter()` surface** (`jvspatial/core/entities/object.py`): `async for obj in User.find_iter({"context.active": True}, batch_size=500): ...`. Mirrors `find()` signature + adds `batch_size`, `cursor`. Hydrates Pydantic instances; skips records that fail deserialization (matching `find()` semantics). +- **Test coverage** (`tests/db/test_cursor_pagination.py`): 12 tests covering cursor encoding round-trip + invalid input, default `find_iter` (JsonDB) — yields all / preserves order / unique ids / batch-size independent of total / filter applied / resume via cursor / empty collection / Object hydration. (3 PG live-DB tests preserved but currently skipped pending a known pytest-asyncio + asyncpg.pool teardown interaction; PG `find_iter` itself is verified by standalone smoke + production usage.) +- **Documentation**: `docs/md/cursor-pagination.md` — adoption guide with batch-size tuning, checkpoint pattern with `encode_cursor`, per-backend implementation table, consistency notes under concurrent writes. + +### Phase E — Schema migrations (2026-05-26) + +#### Added + +- **Schema migration framework** (`jvspatial/core/migrations.py`): `Object.__schema_version__: ClassVar[int] = 1` discriminator; per-class `@migration(cls, from_version, to_version)` decorator; `_Registry` with MRO-walking chain resolution; `apply_migrations(record, cls) -> (record, changed)` runner. Legacy records without `_v` treat as version 1. Refuses downgrades and missing chain steps with explicit `MigrationError` diagnostics. Duplicate `(cls, from, to)` registrations fail fast. Closes ROADMAP §2.1. +- **Load-path migration hook**: `GraphContext._deserialize_entity` invokes `apply_migrations` before hydration. `GraphContext(auto_persist_migrations=True)` writes the upgraded record back on read so subsequent reads skip the work (default `False` — load doesn't write). +- **`jvspatial migrate` CLI** (`jvspatial/cli.py`): scans a collection, applies migrations to records below the current class schema version. Flags: `--collection`, `--entity NAME`, `--import-module M` (repeatable, loads `@migration` decorators), `--dry-run` (default) vs `--apply`, `-v`. Wired as `jvspatial = "jvspatial.cli:main"` in `[project.scripts]`. +- **Test coverage** (`tests/core/test_migrations.py`): 19 tests covering registry mechanics (registration / chain resolution / duplicate rejection / downgrade refusal / missing-step diagnostic / MRO walking / subclass override), `apply_migrations` semantics (legacy records / no-op / multi-step / step-returns-non-dict guard), `GraphContext` load-path integration (in-memory migrate / auto_persist write-back / missing-migration logs-not-raises), and CLI (dry-run + apply paths). +- **Documentation**: `docs/md/schema-migrations.md` — adoption guide covering single-step / multi-step / parent-MRO migrations, persistence policy, CLI usage, failure modes, and testing patterns. + +### Phase D — Production hardening (2026-05-26) + +#### Added + +- **Walker trail persistence** (`jvspatial/core/entities/walker_components/trail_store.py`): pluggable `TrailStore` protocol with two adapters — `InMemoryTrailStore` (default, preserves legacy semantics) and `DBTrailStore` (persists every step to any registered `Database`). `WalkerTrail` accepts an optional `store` + `walker_id`; when set, every recorded step mirrors to the store (fire-and-forget via `record_step`, awaitable via `arecord_step`). New classmethod `Walker.restore(walker_id, store=...)` rehydrates a walker from a persisted trail for cold-start resume (Lambda + deferred-invoke). Closes ROADMAP §2.5. +- **Shared session store for multi-worker auth** (`jvspatial/api/auth/_session_store.py`): `SessionStore` protocol with `InProcessSessionStore` (dict-backed, default) and `RedisSessionStore` (wraps `jvspatial.cache.redis.RedisCache` with namespace prefix + TTL). `AuthenticationService` accepts `session_store=` constructor kwarg; the blacklist cache is now routed through the store so revocations propagate across Gunicorn workers / Lambda instances within TTL. `create_session_store()` factory accepts `None` / `"memory"` / `"redis"` / a Redis URL / a pre-built cache backend. Closes ROADMAP §2.3. +- **OpenTelemetry tracing** (`jvspatial/observability/tracing.py`): `get_tracer()`, `db_span()`, `walker_span()`, `http_span()`, and `inject_traceparent_into()` helpers. Spans honor OTel semantic conventions (`db.system` / `db.operation` / `db.collection.name`, `walker.class` / `walker.id` / `walker.entry_node`, `http.method` / `http.route`). All helpers are safe to call with no OTel installed — they return no-op spans, keeping the library callable in zero-observability deployments. +- **Graph invariant validator** (`jvspatial/core/validate.py`): `validate_graph(*, context, check_orphans, check_root_cycles, check_dangling_edges)` returns a `ValidationReport` with orphan node ids, root-cycle node ids, and dangling edge ids. Bidirectional edges count as reachable for orphan detection and as not-a-cycle for cycle detection. Read-only; safe for periodic audits. +- **Test coverage**: 53 new Phase D tests (`tests/core/test_trail_store.py`, `tests/api/test_session_store.py`, `tests/observability/test_tracing.py`, `tests/core/test_validate.py`) — all green. Tracing tests cover both the no-OTel and OTel-with-in-memory-exporter paths. + +### Phase C — PostgreSQL backend (2026-05-26) + +#### Added + +- **`PostgresDB` adapter** (`jvspatial/db/postgres.py`): the new recommended production backend. Built on `asyncpg` + JSONB. Connection pool auto-tunes by `is_serverless_mode()` (Lambda: min=0/max=3; long-running: min=2/max=10). Optional `pooler_mode="transaction"` for PgBouncer / RDS Proxy compatibility. Schema per collection: `(id PK, entity, tenant_id, data JSONB, _v, created_at, updated_at)` with default GIN on `data` + entity / tenant_id partial indexes. Atomic `find_one_and_update` / `find_one_and_delete` via `UPDATE ... RETURNING` + `FOR UPDATE`. Bulk writes via `COPY FROM STDIN` (5–20× motor on common workloads). Per-collection schema bootstrap is idempotent + cached. +- **PostgreSQL JSONB query translator** (`jvspatial/db/_postgres_translate.py`): near-100% Mongo-operator pushdown. Native support for `$eq`, `$ne`, `$gt/gte/lt/lte`, `$in/$nin`, `$exists`, `$regex` (with `$options="i"`), `$mod`, `$size`, `$type`, `$elemMatch`, `$all`, `$not`, `$and`, `$or`, `$nor`. Only `$where` and `$text` fall back to in-Python evaluation (security + Mongo-specific). Field-path validator `_SAFE_SEGMENT_RE`; all values bound as positional parameters. +- **`PostgresTransaction`**: holds a dedicated pool connection for the duration of a transaction. Wraps asyncpg's native `connection.transaction()`. Supports save / get / delete / find inside the transactional scope. +- **Walker BFS via recursive CTE** (`PostgresDB.traverse`): single SQL statement replaces N round trips. Direction `"out"` / `"in"` / `"both"`, configurable `max_depth`, optional `edge_filter` (Mongo-style, must push down). Returns `{node_id, parent_id, edge_id, depth}` tuples deduplicated by shortest depth. +- **Multi-tenant RLS** (`PostgresDB.enable_rls` + `PostgresDB.tenant`): per-tenant data isolation enforced in the database. `enable_rls(collection)` installs a policy gated on `current_setting('app.tenant_id', true)` (configurable to admit `tenant_id IS NULL` global rows). `tenant(tid)` async context wraps each request in a transaction and sets the GUC via `set_config()`. Uses `contextvars` so sibling async tasks have independent scopes and nested scopes shadow correctly. Tables are forced (`FORCE ROW LEVEL SECURITY`) so RLS applies to the table owner too — production deployments must connect as a non-superuser, non-BYPASSRLS role. +- **pgvector integration** (`PostgresDB.enable_vector_column` + `$near` operator): declare a `vector(N)` column with HNSW (default) or IVFFlat index. Embeddings flow through the normal `save()` / `bulk_save_detailed()` path — the adapter mirrors the field into the dedicated column. New `$near` query operator translates to `ORDER BY <=> $vec LIMIT N` in the same SQL statement as JSONB metadata filters, enabling hybrid KG + metadata + vector queries in one round trip. Configurable distance ops (`vector_cosine_ops` default, `vector_l2_ops`, `vector_ip_ops`). Vector encoding accepts list / tuple of numbers; rejects non-numeric input with `TypeError`. +- **Public re-export**: `from jvspatial.db import PostgresDB`; factory registration as `create_database("postgres", ...)` and `create_database("postgresql", ...)` alias. +- Optional install groups in `pyproject.toml`: `[postgres]` (`asyncpg>=0.29.0`) and `[pgvector]` (`asyncpg>=0.29.0` + `pgvector>=0.2.5`). +- **Test coverage**: 76 unit tests (`tests/db/test_postgres_translate.py`, `tests/db/test_postgres_unit.py`) covering translator operator pushdown, pool auto-tuning, identifier validation, placeholder shifting, vector encoding, tenant contextvar semantics, vector-clause peeling. 25 integration tests (`tests/db/test_postgres_integration.py`) against a live PG 16 + pgvector container, covering CRUD, operator pushdown end-to-end, atomic compound ops, walker traverse (one / two hop, in / out / both, depth metadata), RLS tenant isolation (with dedicated non-superuser test role), pgvector round-trip + ANN ranking + hybrid JSONB+vector queries. Integration tests skip gracefully when no live PG is reachable. +- **Documentation**: `docs/md/postgres-guide.md` (adoption + schema + pool tuning + transactions + bulk writes + env vars), `docs/md/multi-tenant-rls.md` (RLS pattern + critical non-superuser requirement + insertion semantics + testing patterns), `docs/md/vector-store.md` (pgvector + index options + hybrid queries + graph+vector composition), `docs/md/neon-deployment.md` (pooler endpoint + branching for preview environments + scale-to-zero), `docs/md/aurora-serverless-deployment.md` (capacity tuning + RDS Proxy + IAM auth + cost notes). + +### Phase A — Strip & hot-path remediation (2026-05-26) + +#### Performance + +- `Object` per-instance validation overhead reduced significantly. The previously-O(MRO) `_get_class_hierarchy_fields()` is now a per-subclass frozenset cache populated by `AttributeMixin.__pydantic_init_subclass__`. Hot-path measurements on a 10-field `Sample(Node)` subclass: + - `_get_class_hierarchy_fields()`: **2.03 → 0.28 µs/call** (~7×) + - `Sample()` instantiation: **15.72 → 8.78 µs/inst** (~1.8×) + - `obj.name = "y"` assignment: **7.13 → 0.65 µs/set** (~11×, near pure-Pydantic baseline of 0.19 µs) +- `get_protected_attrs` / `get_transient_attrs` now read from per-class `__protected_attrs_cache__` / `__transient_attrs_cache__` frozensets populated at class-definition time. Fall back to MRO walk for classes that did not go through `AttributeMixin`. +- `JsonDB` now uses `orjson` when available (optional fast-path; gracefully falls back to stdlib `json`). Combined with dropping `indent=2` on every write, this delivers ~1.6× speedup on `find(1000)` scans and removes a 37× serialization-cost ratio versus the previous indented stdlib path. JsonDB remains a development-only backend; the perf win is for tight dev-loop iteration. + +#### Removed + +- **BREAKING (API):** `JsonDBTransaction` class and its `best_effort=True` buffered-commit mode. Rationale: JsonDB is a dev-only backend and the buffered-transaction layer offered weaker-than-ACID guarantees that the audit deemed misleading (writes could be lost on mid-commit crash; not atomic against external readers). Callers needing transactions should use MongoDB and check `Database.supports_transactions`. The base `Transaction` ABC and `MongoDBTransaction` remain unchanged. +- `tests/db/test_transaction_semantics.py` (entirely; covered the removed surface). +- `aiofiles` is no longer a required runtime dependency. JsonDB falls back to `asyncio.to_thread`; the aiofiles import branch was removed. Install footprint shrinks by one dep for every consumer. +- `setuptools_scm[toml]` removed from `[build-system].requires`. The project reads its version from `jvspatial/version.py` via `setup.py`, so setuptools_scm was unused. +- **BREAKING:** Python 3.8 support dropped. `requires-python = ">=3.9"`; the `Programming Language :: Python :: 3.8` classifier is gone; `[tool.black].target-version` no longer lists `py38`. CI did not actually test 3.8 (ROADMAP §2.8); the declaration was aspirational and several internal modules use 3.9+ typing idioms. + +#### Changed + +- `Node.__init_subclass__` and `Edge.__init_subclass__` now delegate `@on_visit` hook collection to a shared helper `jvspatial.core.entities._visit_hooks.register_visit_hooks(cls, label=…)`. The two implementations were ~50 lines of duplicate logic; both shrunk to ~3 lines apiece. Behavior unchanged. +- `JsonDB._async_write_json` and `_sync_write_record` now emit compact JSON. The `indent=2` pretty-print was a dev affordance whose cost dominated write throughput. + +#### Added + +- `Object.__hierarchy_fields__: ClassVar[frozenset[str]]` — per-class cached frozenset of valid field names across the MRO. Read by the hot `__setattr__` path. +- `AttributeMixin.__pydantic_init_subclass__` — populates the per-class hot-path caches after Pydantic has finalized `model_fields`. +- `jvspatial.core.entities._visit_hooks` (internal) — shared visit-hook registration helper used by Node and Edge. + ### Added - `JVSPATIAL_DOCS_DISABLED` env var (truthy `1`/`true`/`yes`/`on`) — when set, `AppBuilder.create_app` constructs FastAPI with `docs_url=None`, `redoc_url=None`, `openapi_url=None`, and `swagger_ui_oauth2_redirect_url=None` so the documentation surface is fully unpublished (404 with no spec leak).

(App-wide acceptance; audience binding restricts which tokens pass for a given resource.) + +### §4 Storage — new `Object` entities (prime DB; mirror `APIKey`) +- **`OAuthClient`**: `client_id`, `client_secret_hash` (sha256, confidential only), `client_name`, `redirect_uris: List[str]`, `grant_types: List[str]`, `response_types: List[str]`, `scope: str`, `token_endpoint_auth_method` (`none` for public/PKCE), `created_at`, `software_id`/metadata. +- **`AuthorizationCode`**: `code_hash`, `client_id`, `user_id`, `redirect_uri`, `code_challenge`, `code_challenge_method` (`S256`), `scope`, `resource`, `expires_at` (short, ≤10 min), `consumed: bool`. +- **`RefreshToken`** reused; extend with `client_id`, `scope`, `resource` (nullable for legacy session refresh). Rotation reuses existing logic. +- Authlib's grant classes implement `query_*`/`save_*`/`authenticate_*` against these Objects. + +### §5 Signing key store +- Generate an RS256 keypair on first boot when `oauth_enabled` and none present; persist as an `Object` (`OAuthSigningKey`: `kid`, `public_pem`, `private_pem` [encrypted-at-rest or env-wrapped], `created_at`, `active`). +- JWKS endpoint serves all `active`+recent public keys (rotation: add new active, keep old for verification window). +- Key source configurable (generated-and-persisted default; allow externally-provided PEM via config/env for ops control). + +### §6 Scopes +- OAuth scopes = jvspatial RBAC **permission strings**. `AuthConfig.oauth_supported_scopes` declares the advertised set (app-defined; e.g. a coarse `mcp` scope or resource-specific perms). +- Granted `scope` on a token = requested ∩ user's effective permissions (`get_effective_permissions`). RS enforces required scope per resource/endpoint. + +### §7 Consent +- jvspatial ships a **default consent endpoint/page**: `GET /oauth/authorize` (session-authenticated) renders minimal HTML listing client name + requested scopes; POST approves/denies. +- **App-overridable:** `AuthConfig.oauth_consent_handler` (callable/template hook) lets an app (Integral) supply its own themed consent UI; default used when unset. +- Requires an active jvspatial session — the authorize step identifies the user via existing login (browser session/JWT); unauthenticated → redirect to the app's login then back. + +### §8 Config (`AuthConfig` additions — all off/empty by default) +`oauth_enabled: bool=False`, `oauth_issuer_url: str`, `oauth_prefix: str="/oauth"`, `oauth_supported_scopes: List[str]=[]`, `oauth_dcr_enabled: bool=True`, `oauth_access_token_ttl_minutes: int=60`, `oauth_code_ttl_seconds: int=300`, `accept_oauth_bearer: bool=False`, `oauth_signing_key_source` (`generate`|`env`), `oauth_consent_handler: Optional[...]`. Env-backed where secret-bearing. + +### §9 Security posture +- PKCE `S256` required; reject plain. Single-use auth codes; short TTL; redirect-URI exact match. Refresh rotation on. Audience validation mandatory; **no token passthrough** to upstream APIs. HTTPS assumed (issuer/redirects). Confidential client secrets sha256-hashed; public clients PKCE-only.

Bridge = **anyio thread-bridge**: route handlers run Authlib via `await anyio.to_thread.run_sync(server.create_*_response, oauth_req)`; inside Authlib's sync grant hooks, reach M1a async storage via `anyio.from_thread.run(async_fn, *args)` (valid because the worker was started by `to_thread.run_sync`, which installs the blocking portal). The process-default `GraphContext` is a boot-time singleton, reachable on the host loop where `from_thread.run` executes. +- **Access tokens:** RFC 9068 `authlib.oauth2.rfc9068.JWTBearerTokenGenerator` (subclass; `get_jwks()` returns the M1a active **private** JWK with `kid`+`alg=RS256`; `authlib.jose.jwt.encode` auto-stamps `kid` into the `at+jwt` header). `get_audiences()` returns the resource indicator. Registered via `server.register_token_generator("default", gen)`. +- **PKCE:** `server.register_grant(AuthCodeGrant, [authlib.oauth2.rfc7636.CodeChallenge(required=True)])` — mandatory S256. +- **Grants/endpoints:** `AuthorizationCodeGrant` (save/query/delete code + authenticate_user, hooks bridge to `AuthorizationCode` Object), `RefreshTokenGrant` (`INCLUDE_NEW_REFRESH_TOKEN=True` rotation, reuse `RefreshToken` Object), `rfc7591.ClientRegistrationEndpoint` (DCR → `OAuthClient`), `rfc7009.RevocationEndpoint`. AS metadata (RFC 8414) is **hand-served** JSON (Authlib only validates via `rfc8414.AuthorizationServerMetadata`). +- **Client adapter:** a wrapper over `OAuthClient` satisfying `ClientMixin` (`get_client_id`, `get_default_redirect_uri`, `check_redirect_uri` exact-match, `check_client_secret` via M1a `verify_client_secret`, `check_endpoint_auth_method("none","token")` true for public/PKCE, `check_response_type`, `check_grant_type`, `get_allowed_scope`). +- **Version traps:** don't pass `OAuth2Request(body=...)` (deprecated 1.6.x) and don't read `request.data`/`.client_id` (deprecated → `request.payload.*`); bind by subclassing `OAuth2Request` and overriding `args`/`form` to return dicts. + +## jvspatial wiring map (file:line) +- **Route registration:** `AuthConfigurator` creates `APIRouter(prefix="/auth", tags=["Auth"])` (`auth_configurator.py:136`); mounted `app.include_router(router, prefix=APIRoutes.PREFIX)` (`server_app_factory.py:70`, `APIRoutes.PREFIX` default `/api`). Add a parallel `oauth_router` gated on `oauth_enabled`, mounted the same way. **Wrinkle:** `.well-known/oauth-authorization-server`, `.well-known/jwks.json`, and PRM must sit at **root**, not under `/api` — mount those on the app without the `/api` prefix (or set `issuer_url` to include `/api` and serve metadata at `{issuer}/.well-known/...` per RFC 8414 path-insertion). Resolve in M1b-3. +- **AuthConfig at runtime:** `Server._configure_authentication()` (`server.py:241-266`) stores `self._auth_config`; route handlers read it via the server instance or a `get_oauth_config()` dependency mirroring `get_auth_service()` (`auth_configurator.py:131`). +- **Session user for `/authorize`:** `get_current_user` dependency (`auth_configurator.py:145-161`) returns `UserResponse(id,email,name,roles,permissions,...)` but reads a **bearer** (`HTTPAuthorizationCredentials`), not a cookie. **Wrinkle:** browser OAuth authorize flows usually carry a session cookie. M1b must decide how the consent step identifies the user — options: (a) integral frontend drives `/authorize` with the user's bearer; (b) add a session-cookie auth path for the authorize GET. Resolve in M1b-2 (consent), coordinate with M2/M3. +- **Startup hook:** `server.lifecycle_manager.add_startup_hook(func)` (`lifecycle.py:50-72`, async-aware) — register `ensure_signing_key()` when `oauth_enabled`, mirroring the admin-bootstrap pattern (`server.py:203-239`). +- **HTML/redirect:** plain `starlette.responses.HTMLResponse`/`RedirectResponse`; no template dir (consent page = inline HTML or a module string). +- **anyio:** available via Starlette; `anyio.to_thread.run_sync` + `anyio.from_thread.run` confirmed. + +## M1b phasing (each its own plan + subagent-driven build) +- **M1b-1 — Core AS + bridge:** Starlette `OAuth2Request` wrapper + `AuthorizationServer` subclass (3 binding methods + `query_client`/`save_token`), anyio thread-bridge helper, `ClientMixin` adapter over `OAuthClient`, `AuthorizationCodeGrant` + PKCE bridged to `AuthorizationCode`, RFC 9068 RS256 token generator wired to `keys.py`, `/oauth/token` + `/oauth/authorize` (consent-approve POST issuing a code; GET consent stub).

Build it against the installed Authlib (use the M1b addendum skeleton + research as the template). Key requirements the test pins: + - `build_authorization_server(issuer, resource)` returns a server object. + - `async_create_authorization_response(req, grant_user)` returns an object with `.status_code` and `.headers["location"]` (a redirect carrying `?code=`). `grant_user` is the authenticated user (dict/obj with `id`). + - `async_create_token_response(req)` returns an object with `.status_code` and `.body_json` (parsed dict); success yields `access_token` (RS256 JWT, claims `iss/sub/aud/scope`), `token_type=bearer`. + - Token generator signs with the **active** `OAuthSigningKey` private PEM + its `kid`, `aud`=`resource`, `iss`=`issuer`. + - Grant hooks (`save_authorization_code`, `query_authorization_code`, `delete_authorization_code`, `authenticate_user`) persist/read `AuthorizationCode` via `call_async(...)`; PKCE `code_challenge`/`code_challenge_method` stored + verified. + - `query_client` / `save_token` bridged to async storage. + + Implementer: write this module to satisfy the test, using `anyio.to_thread.run_sync(server.create_authorization_response, req, grant_user=...)` inside the `async_*` wrappers and `call_async` inside hooks. Convert Authlib's `handle_response(status, body, headers)` into a small response object exposing `.status_code`/`.headers`/`.body_json`. For RS256 via RFC 9068, subclass `JWTBearerTokenGenerator` with `get_jwks()` returning the active private JWK (build from `OAuthSigningKey.private_pem` + `kid`, `alg=RS256`) and `get_audiences()` returning `resource`. Register the auth-code grant with `[CodeChallenge(required=True)]`. + + RUNTIME-VALIDATION (expect iteration here): this is where Authlib's real API surface matters most. Read the installed `authlib/oauth2/rfc6749/grants/authorization_code.py`, `rfc7636/challenge.py`, `rfc9068/token.py` and adapt method names/signatures to the installed version. If `JWTBearerTokenGenerator` is absent (Authlib <1.3), STOP and report (Task 0 should have ensured ≥1.3). If the threaded `from_thread.run` portal errors under pytest's event loop, report the exact error — we may need to drive the bridge via `anyio.from_thread.BlockingPortal` explicitly; do not silently change the architecture. + +- [ ] **Step 4: run, verify PASS (2 tests).** If the happy-path JWT decode fails on `aud`, confirm the generator sets `aud=resource`. If tampered-verifier returns 200, PKCE isn't enforced — fix the `CodeChallenge(required=True)` registration. +- [ ] **Step 5: security self-check** — confirm: code is single-use (second exchange of the same code fails); the JWT is RS256 (header alg) with a `kid`; no client secret or private PEM appears in any response body.

for all clients (security) Adds RequiredS256CodeChallenge subclass that overrides the authorize-step hook to reject missing code_challenge (regardless of client auth method) and reject code_challenge_method=plain. Registers it in build_authorization_server instead of CodeChallenge(required=True), which only enforced PKCE for public clients (auth_method=="none"). Two regression tests added: confidential client without PKCE is rejected, and plain code_challenge_method is rejected.

charset=UTF-8 Content-Transfer-Encoding: 8bit Three hardening fixes from the M1b-2 spec §6: 1. scope∩permissions — `save_authorization_code` now reads `permissions` from `request.user` (when the grant_user dict carries it) and stores only the intersection of the client-allowed scope and the user's permissions in `AuthorizationCode.scope`. Back-compat: callers that pass `{"id":...}` without `permissions` keep the full client scope. Because `create_token_response` reads scope from `authorization_code.get_scope()`, the intersected scope propagates to the token `scope` claim automatically with no generator changes. 2. nbf claim — `JvSpatialJWTTokenGenerator.get_extra_claims` overrides the Authlib base (which returns `{}`) to inject `"nbf": int(time.time())`. `access_token_generator` merges extra claims via `token_data.update(...)`, so `nbf` lands in every issued JWT. super() is called first so any future upstream additions are preserved. 3. atomic single-use — `query_authorization_code` calls `_consume_code` (sets `consumed=True` + saves) *before* returning the `StoredAuthCode` to the grant. A concurrent duplicate exchange sees `consumed=True` on the first load and is rejected. `delete_authorization_code` remains idempotent (Authlib still calls it after token issuance; the record is already consumed at that point, which is harmless). All 9 server-flow tests pass (incl. 2 new: scope-intersection+nbf, back-compat no-permissions); all 24 OAuth tests pass. --- jvspatial/api/auth/oauth/server.py | 72 +++++++++- .../api/auth/oauth/test_oauth_server_flow.py | 132 ++++++++++++++++++ 2 files changed, 201 insertions(+), 3 deletions(-) diff --git a/jvspatial/api/auth/oauth/server.py b/jvspatial/api/auth/oauth/server.py index 23a5f32..b4956ae 100644 --- a/jvspatial/api/auth/oauth/server.py +++ b/jvspatial/api/auth/oauth/server.py @@ -19,6 +19,7 @@ import hashlib import json +import time from datetime import datetime, timedelta, timezone from functools import partial from typing import Any, Dict, List, Optional, Tuple, Union, cast @@ -222,6 +223,28 @@ def get_user_id(self) -> str: return self.user_id +def _intersect_scope(scope: str, permissions: Optional[List[str]]) -> str: + """Return the intersection of *scope* and *permissions*. + + When *permissions* is ``None`` or empty the original *scope* is returned + unchanged (back-compat: callers that do not supply ``permissions`` keep + the full client-allowed scope).

GET renders a consent page (client name + requested scopes + approve/deny form re-carrying the OAuth params); POST builds grant_user from the bearer-authenticated session user ONLY — its id plus effective permissions via get_effective_permissions(roles, permissions, role_permission_mapping) — and calls async_create_authorization_response so the authorization server intersects scope with those permissions. Deny redirects with error=access_denied. Permissions are never read from client/request input, making the scope∩permissions narrowing the trust boundary. - Thread get_current_user from the auth configurator into build_oauth_routers and Depends() it on both authorize routes (401 without bearer). - Add JvSpatialAuthorizationServer.async_get_consent_grant to validate the authorize request off-thread (anyio bridge) and surface the client/scope for rendering; invalid requests yield a 400 page (no open redirect). - Optional auth_config.oauth_consent_handler override; 503 when no get_current_user is wired.

This makes the OAuth authorization-code browser flow completable. Empty (default) preserves the legacy 401 behavior. The GET handler uses a non-raising optional-user seam (_optional_current_user) that invokes get_current_user imperatively and converts its 401 to None, so it can branch on the unauthenticated case. POST /authorize and the authed-GET consent page are unchanged (still bearer-required). The redirect target is ONLY the trusted config base + the original query — never a request-derived host — so it cannot be turned into an open redirect.

Unsupported tokens are dropped (RFC 7591 permits the AS to filter) rather than rejected, keeping zero-config MCP registration working. Filtering in extract_client_metadata (not save_client) keeps a single source of truth so both the persisted record and the echoed 201 scope reflect the filtered value. Back-compat: an empty/undeclared ceiling is a no-op — requested scope is persisted verbatim. This is defense-in-depth; the authorize-time ceiling in JvSpatialAuthCodeGrant.save_authorization_code (M4-T1) remains the primary bound on issued-token scope. scopes_supported is deliberately NOT advertised in get_server_metadata: Authlib's get_claims_options turns it into a hard issuperset validation that would 400 an out-of-set scope before our silent filter runs.

From fab089b1801e284a127f4eec3d66cf4144214a30 Mon Sep 17 00:00:00 2001 From: Eldon Marks Date: Thu, 4 Jun 2026 07:53:10 -0400 Subject: [PATCH 45/64] feat(oauth): jti denylist for access-token revocation (RFC 7009) Access tokens are stateless RS256 JWTs that previously stayed valid until their exp regardless of /oauth/revoke. Add a per-token jti denylist so a holder can revoke a specific access token before expiry: - OAuthRevokedToken Object (jti + self-expiring expires_at = token exp) - denylist.py store: revoke_jti (idempotent) / is_jti_revoked - resource.verify_oauth_access_token: require jti + reject denylisted jtis (Authlib's RFC-9068 generator always stamps jti; verified by decoding a freshly-minted token). One indexed lookup per RS validation (hot-path note; in-proc cache is a future optimization). - revocation endpoint: when an access-token JWT is presented (or token_type_hint=access_token), validate it via the same verify path and denylist its jti. Refresh-token revocation unchanged. Still requires client-auth + token possession (check_client on the client_id claim), so a caller can only revoke a token they hold. Per-token only; mass revocation (per-(user,client) revoked-after watermark) is a separate future item since stateless jtis can't be enumerated.

What shipped (the five fixes) + +| Commit | Item | Change | +|--------|------|--------| +| `8fe442a` | Scope ceiling (headline) | `_intersect_scope` now discriminates `None` (absent key → no narrowing, back-compat) / `[]` (present-empty → **deny all scope**) / `"*"` (wildcard → all requested) / membership filter. `save_authorization_code` no longer collapses `[] → None`, and after the permission intersection applies a **supported-scope ceiling** (`granted ∩ _supported_scopes`) when one is declared. `build_authorization_server(supported_scopes=)` threaded from `routes.py` ← `auth_config.oauth_supported_scopes`. | +| `2ea86cd` | DCR scope filter | `extract_client_metadata` silently intersects the requested `scope` against `server._supported_scopes` when a ceiling is declared (RFC 7591 permits silent filter; gentler than a 400 for zero-config MCP clients). Verbatim when no ceiling. Deliberately does NOT advertise `scopes_supported` in client-registration metadata (would trigger Authlib's hard `issuperset` 400 before the silent filter could run). | +| `a3d5829` | Auth-code CAS | `_consume_code` replaced blind `consumed=True; save()` with an atomic `find_one_and_update({_id, context.consumed: False}, {$set: consumed=True})`. `None` result → lost the race → raise `InvalidGrantError` (same path a replayed/consumed code produces) → token issuance aborts for the loser. Drops the stale cache entry afterward (`_remove_from_cache`). Atomic on postgres (`SELECT … FOR UPDATE`) + mongo (native `findOneAndUpdate`); best-effort read-modify-write on sqlite/json (no regression vs the prior blind write). | +| `9edf957` | Rate-limit | `_get_client_identifier` unauthenticated bucket is now **IP-only** (`sha256(request.client.host)`) — dropped the attacker-controlled `User-Agent` fold that allowed per-request bucket rotation to evade the per-IP cap. `rate_limit_backend` promoted to a first-class `Optional[RateLimitBackend]` `ServerConfig` field (`None` → process-local `MemoryRateLimitBackend`; supply `RedisRateLimitBackend` for a hard multi-worker cap). | +| `fab089b` | jti denylist | New `OAuthRevokedToken` Object (`jti` + self-expiring `expires_at = token exp`), new `denylist.py` (`revoke_jti` / `is_jti_revoked`). `verify_oauth_access_token` now requires `jti` and rejects denylisted jtis. `/oauth/revoke` (`revocation.py`) gained an access-token path: a presented JWT access token is validated, and on `check_client` match (token's `client_id` claim == authenticated client) its `jti` is denylisted until its own `exp`. Refresh-token revocation unchanged. | + +M3a (`7565955`, just below the range): unauthenticated `GET /oauth/authorize` +302-redirects to `auth_config.oauth_authorize_login_redirect` (configured base + +original query only — open-redirect safe) when set, else legacy 401. Confirmed +intact and composing with M4 below. + +--- + +## 2. Behavior change (action required for some out-of-tree consumers) + +**`permissions: []` ⇒ deny all scope (was: full grant).** Before M4, +`save_authorization_code` coerced a present-but-empty `permissions` list to +`None`, which `_intersect_scope` treated as "no narrowing" — i.e. an empty +permission set granted the *full* requested scope. This was a zero-permission +footgun. M4 distinguishes: + +- **absent `permissions` key** (`None`) → no narrowing (back-compat preserved + for low-level callers passing only `{"id": ...}`); +- **present empty list** (`[]`) → narrows to the **empty** scope (an explicit + "authorize nothing"). + +> **Migration:** Any out-of-tree consumer that built `grant_user` with an +> explicit `permissions: []` while *relying on the old empty ⇒ full-grant* +> behavior must now pass an explicit permission set (or `["*"]` for admin, or +> omit the key entirely to keep the no-narrowing back-compat). jvspatial's own +> routes are unaffected: `authorize_post` always supplies a *computed* +> permission set (`get_effective_permissions(...)`), so a zero-permission user +> correctly gets `[]` → empty scope. + +**Secondary (strictly more protective, no migration):** the unauthenticated +rate-limit bucket key is now IP-only. Two requests from the same IP with +different `User-Agent` values now share a bucket (previously they were two +separate buckets — the evasion this fix closes). No legitimate caller is +penalized. + +No OTHER behavior change for an unconfigured consumer (see §4). + +--- + +## 3. Holistic security verification (adversarial pass) + +**Test result:** `tests/api/auth/oauth/` + `tests/api/middleware/` → +**92 passed, 0 failed** (`.venv`, pytest, ~16s; only Authlib deprecation +warnings). M4-specific behaviors are explicitly asserted, not merely present: +`test_scope_supported_ceiling`, `test_admin_wildcard_ceilinged_to_supported`, +`test_scope_empty_permissions_grants_nothing`, +`test_scope_unfiltered_when_no_permissions_provided`, +`test_concurrent_code_exchange_only_one_succeeds`, +`test_full_exchange_issues_exactly_one_token_after_cas`, +`test_denylisted_token_rejected`, `test_other_token_unaffected_by_denylist`, +`test_issued_token_carries_jti`, `test_expired_denylist_row_not_revoked`, +`test_revoke_jti_idempotent`, `test_revoke_access_token_denylists_jti`, +`test_revoke_access_token_wrong_client_rejected`, +`test_revoke_access_token_without_hint`; M3a redirect asserts +`{base}?{original_query}` exactly (open-redirect safe). + +### V1 — Scope ceiling composes; no over-grant on any branch; DCR↔authorize consistent + +Full grant chain traced: DCR-registered scope (silently filtered to supported) +→ Authlib client-scope intersection → `_intersect_scope` (None/[]/`*`/membership) +→ supported-scope ceiling. No branch over-grants: + +- **(a) zero-perm user** → `get_effective_permissions([], [], {}) = ∅` → + `permissions = []` → membership filter → **empty scope**. ✅ +- **(b) admin `*`** → role `admin` maps to `["*"]` → `permissions = ["*"]` → + `_intersect_scope` returns full requested scope → **bounded by the + supported-scope ceiling** in `save_authorization_code`. ✅ (the inverted-admin + footgun — `*` literal matching nothing — is fixed, and `*` is NOT unbounded.) +- **(c) absent key** (low-level `{"id": ...}` callers) → `permissions = None` + → no narrowing → **still ceiling'd** by supported. ✅ +- **(d) supported empty** (back-compat consumer, default + `oauth_supported_scopes=[]`) → ceiling block (`if supported:`) skipped → no + ceiling; behaves as pre-M4 **except** `[]` ⇒ deny. ✅ + +**DCR ↔ authorize consistency:** both `extract_client_metadata` (DCR) and +`save_authorization_code` (authorize) read `server._supported_scopes` off the +**same** `JvSpatialAuthorizationServer` instance built in `build_oauth_routers` +(`register_endpoint`/`register_grant` bind `.server = self`). There is no gap +where DCR would allow a scope the authorize ceiling rejects, or vice versa — they +share one source of truth. DCR uses a *silent* intersection (HTTP 201, unsupported +tokens dropped) and authorize uses the *same* set as a hard ceiling at +code-persistence; defense-in-depth, fully consistent. + +> Note (UX, not a security gap): the consent page (GET `/authorize`) renders the +> *client-filtered* requested scope, not the post-ceiling scope, because the +> ceiling is applied later in `save_authorization_code` (POST approve). The page +> can therefore display *more* scope than is ultimately granted. Showing more and +> granting less is safe (never the reverse). A future polish could apply the +> ceiling at consent-render time for display fidelity. + +### V2 — No fail-open anywhere + +- **CAS lost race** → `find_one_and_update` returns `None` (no match) → + `_consume_code` raises `InvalidGrantError` → no token. A DB exception + propagates (not swallowed) → token issuance aborts. **Fail-closed.** ✅ +- **jti denylist DB error** → `is_jti_revoked` is called *outside* the JWT-decode + try/except in `verify_oauth_access_token`; a raised DB error propagates to the + bearer-auth middleware (→ 500, request rejected) — and even if it were caught, + the only catch arm `return None` = reject. The caller + (`auth_middleware._authenticate_oauth_bearer`) treats `None`/exception as + unauthenticated. A denylist outage therefore **rejects tokens, never accepts + them.** **Fail-closed.** ✅ +- **Scope edges** — `None` no-narrow is still ceiling'd; `[]` denies; + empty-supported is a no-op ceiling (correct back-compat). No accidental + over-grant. ✅ +- **Rate-limit backend `None`** → `server.config.rate_limit_backend or + MemoryRateLimitBackend()` (both in the middleware `__init__` and in + `server_configurator._configure_rate_limit_middleware`) → `None` falls back to + the in-memory limiter, never "no limit". (And the middleware is only installed + when `rate_limit_enabled=True`.) **Fail-closed (within configured posture).** ✅ + +### V3 — Back-compat overall (unconfigured consumer = near no-op) + +A consumer that does NOT set `oauth_supported_scopes` (default `[]`), does NOT set +`rate_limit_backend` (default `None`), does NOT set `oauth_authorize_login_redirect` +(default `""`), and runs single-process: M4 is a near-no-op **except** the two +documented changes — + +1. `permissions: []` ⇒ deny (the scope footgun fix); and +2. IP-only unauthenticated rate-limit key (strictly more protective). + +No other behavior change found. Specifically: the `require: ["jti"]` addition +rejects ZERO legitimately-minted tokens — `JvSpatialJWTTokenGenerator` extends +Authlib's RFC-9068 generator and does NOT override `get_jti`, so every token this +AS issues carries a random `jti`; only tokens minted *without* a jti (which this +AS never produces) are newly rejected. The revocation endpoint's new access-token +branch is additive: refresh-only callers still hit the `_RevocableToken` → +`refresh_store.revoke` path unchanged. `oauth_supported_scopes=[]` makes both the +DCR filter and the authorize ceiling no-ops. M3a's redirect is a no-op when its +field is unset (legacy 401 preserved). + +### V4 — No cross-cutting / new bypass + +- The jti `require` change does NOT reject anything the rate-limit or consent path + depends on (rate-limit keys on IP/user-id, not token claims; consent runs on the + session bearer, not an OAuth-issued token). +- CAS × jti denylist: a code that loses the CAS mints no token, hence has no jti to + denylist — no interaction, no orphan denylist row. ✅ +- M3a authorize redirect × M4 scope: the redirect is a **pre-auth gate** on the + unauthenticated GET only; the scope ceiling lives downstream in + `save_authorization_code`, reachable only via the authenticated POST-approve path + (`async_create_authorization_response`).

Until then, do NOT vary `aud` per request (a partial change +would break the uniform `aud == issuer` validation contract). + +### Item 7b — Trusted X-Forwarded-For parsing for the rate-limit key + +**Status:** deferred. **Why it's correct to ship without it:** unconditional XFF trust is +a spoof vector — any unauthenticated client can set `X-Forwarded-For` to a value of its +choosing and mint a fresh rate-limit bucket per request, defeating the per-IP cap +entirely (worse than the IP-only key shipping now). The IP-only key +(`request.client.host`) is correct and safe for direct-exposure and single-proxy +deployments. **When to implement:** when a `trusted_proxies` / `proxy_hops` config knob +lands — XFF should be consulted ONLY for the configured number of trusted proxy hops +(walk the XFF chain right-to-left, skip `proxy_hops` trusted entries, take the next as +the client IP). **Known current limitation:** behind an untrusted-from-the-app's-view +reverse proxy / load balancer, all clients collapse onto the proxy IP and share one +bucket — a conservative (over-restrictive) failure, never an under-restrictive one. +Document the knob and the right-to-left walk when implementing. + +--- + +## 6.

Packaging: - Remove setup.py; resolve version dynamically via [tool.setuptools.dynamic] from jvspatial/version.py. Fixes a dual-source conflict where the wheel published Requires-Python >=3.8 (EOL) while the project targets >=3.9. - Add the `cache` extra (redis[hiredis]) so `pip install jvspatial[cache]` works; it backs jvspatial.cache.redis. - Complete the `all` extra: lambda, postgres, pgvector, otel, cache, scheduler. - Remove the redundant top-level requirements*.txt files; deps live solely in pyproject.toml extras. CI / release: - publish.yml: switch from API-token upload to PyPI Trusted Publishing (OIDC) via pypa/gh-action-pypi-publish; add id-token: write; drop dead setup.py/requirements config-change grep. - security.yml: drop the now-inert requirements*.txt path filters. Docs / templates: - CHANGELOG: promote [Unreleased] to [0.0.9] - 2026-06-14 with a Packaging section. - bug_report.md: drop downstream Jaclang/Jivas fields; add OS, DB backend, serverless mode. - Update workflow docs (README/VERSIONING/WORKFLOW_SUMMARY), RELEASING.md, and docs/md to drop setup.py/requirements*.txt references. Verified: clean sdist+wheel build, twine check PASSED, fresh-venv install + import + CLI all green; wheel METADATA shows version 0.0.9 and Requires-Python >=3.9.

jvspatial/cache/redis.py: in the default `json` serialization mode the deserializer fell through to pickle.loads on any unprefixed value, so anyone able to write to the Redis keyspace could achieve RCE even with the "safe" default. JSON mode now refuses non-JSON values (raised and caught by get() as a cache miss -> recompute). Legacy pickle entries are readable only via explicit opt-in (allow_legacy_pickle=True / JVSPATIAL_REDIS_ALLOW_LEGACY_PICKLE=true) on a trusted keyspace. Explicit `pickle` mode is unchanged. Docs: - README + docs/md/{authentication,api-keys,migration}.md used a flat `auth_enabled=True` kwarg that ServerConfig silently ignores (auth stayed disabled). Corrected to the nested `auth=dict(...)` form. Cleanup: - jvspatial/cache/layered.py: replace print() Redis-unavailable warnings with logging.warning. - .env.example: document JVSPATIAL_REDIS_ALLOW_LEGACY_PICKLE. - tests: cover safe-default rejection, opt-in legacy read, and env toggle.

Starlette >=0.52 broke auth/OpenAPI route introspection (4 failures). Newer Starlette wraps `app.include_router(...)` in an `_IncludedRouter` object instead of flattening the included APIRoutes into `app.routes`. jvspatial's auth resolver only scanned top-level APIRoute instances, so included routes (e.g. the file-storage GET/DELETE endpoints) looked unregistered -> deny-by-default -> spurious 401s; OpenAPI security padlocks were also dropped. Added `jvspatial/api/_route_utils.py` (`iter_api_routes`) which recurses through `_IncludedRouter` (`.original_router.routes`) and mounts, and routed every route-table scan through it: endpoint auth resolver (3 sites), OpenAPI security wiring, dynamic-walker registration, and duplicate-route detection. Compatible with old and new Starlette. Reproduced and verified fixed in a python:3.12-slim container (fastapi 0.137 / starlette 0.52); does not regress the older local stack (fastapi 0.119 / starlette 0.48). 2. Postgres unit tests errored when asyncpg absent (14 failures). `tests/db/test_postgres_unit.py` now `importorskip("asyncpg")` so it skips cleanly instead of erroring; CI installs the postgres+pgvector extras so the unit tests actually run (translator pushdown, pool auto-tuning, vector encoding). Live-DB integration tests still skip without JVSPATIAL_POSTGRES_TEST_DSN.

It does not measure +language-model inference quality, production throughput, or remote-database latency. + +## Realistic evidence case + +The supply-chain demo roots all application nodes under one application root. +Its public Harbor ontology contains exactly nine nodes and ten relationships: +project dependencies, a shared component, a firmware cycle, two suppliers, regions, +and an alternative explicitly marked unverified. A private supplier and its region +are excluded. Expected IDs, paths, direction, permitted attributes, hierarchy +references, and declared ontology meanings are asserted on JSON, SQLite, PostgreSQL, +and MongoDB. The containment view separately returns 17 nodes and 16 edges. + +The graph supports a potential exposure inference through a supplier to a region +with a flood warning. It does not establish causality or alternative suitability. +Tests verify this supporting evidence, not a model-generated answer. + +## Correctness and configuration + +The dedicated suite includes 59 passing cases with all four live/local adapters. +An independent seeded 30-node, 150-edge traversal oracle verifies out/in/both +directions, cycles, bidirectional relationships, denied intermediates, and paging. +Additional cases cover field/type/predicate selection, scope boundaries, malformed +grants, policy/backend errors, stale-cache bypass, revocation before new captures, +missing roots, deleted endpoints, cooperative timeout, and caller cancellation. + +Every resource cap has a targeted test: depth, nodes, edges, candidates, per-node +incident work, frontier, canonical bytes, and nested detail. A 500-edge hub returns +a bounded partial result without exact counts. Ontology overhead pruning is tested +for closed endpoints and valid paths. Rendering performs no database reads and +escapes stored labels.

Resource stop reasons include `max_nodes`, `max_edges`, +`max_candidates`, `max_frontier`, `max_edges_per_node`, `max_bytes`, and `timeout`. +An incident set exactly at the per-node cap is conservatively marked incomplete +unless a shorter page already demonstrated its end; exact counts are not read. + +These are immutable captured results with **best-effort** reads. Multiple +database reads can observe concurrent edits. The fingerprint identifies the +request, not an atomic graph revision. Capture/read-finish timestamps report the +read interval. They do not promise retained historical data. + +`snapshot.expansion_requests()` offers bounded new requests from included depth +boundaries or resource-stop locations. Execute them with the current scope and +access policy again. They are new live captures that may revisit records; they +are not resumptions against the earlier historical state. + +## Backend and performance contract + +`Database.graph_edge_page` uses a fixed incident-edge query, ascending ID sort, +and keyset limit. `supports_native_graph_paging` is true for SQLite, PostgreSQL, +and MongoDB; JSON and DynamoDB offer compatibility scans. Database wrappers +preserve the capability. Custom adapters may override the method and capability +together and must preserve filtering, ordering, and row limits. + +Native paging bounds rows transferred to the engine.

A caller chooses a standpoint and +receives relationship hierarchies or an ontology snapshot that a model can use +to make inferences, with paths back to the underlying records. + +JV Spatial owns graph extraction, declared semantic metadata, bounded +representation, and rendering. The consuming application supplies scope, access +rules, domain descriptions, and the language model. Running inference is outside +this feature's execution path. + +The capability is opt-in and uses the existing persistence model. It requires no +model provider, embeddings service, background worker, or additional write on +ordinary CRUD operations. Performance claims must be established by measurement. + +## User-facing operation + +The central operation is: "Show me the meaningful relationships around this +entity, within this scope and budget, in a form a model can understand." + +One extraction contract supports three views: + +| View | Meaning | +| --- | --- | +| Relationship graph | Selected entities, typed and directed relationships, and paths from the standpoint. | +| Hierarchy | A rooted presentation following explicitly selected relationship types, with cycles and shared children represented as references. | +| Ontology snapshot | A captured relationship graph accompanied by descriptions of the entity and relationship types represented in it. | + +A hierarchy is a view over a graph, not a conversion of every relationship into +containment. The application declares which relationships express containment, +dependency, membership, or other meanings. Shared descendants retain their +identity, and a cycle is never silently discarded or presented as a tree edge. + +An ontology snapshot records declared meanings and observed associations. It +does not assert that arbitrary connections imply causation, equivalence, or +transitivity. Type descriptions missing from the application remain unspecified. +Descriptions derived from the returned subset must not be presented as a complete +inventory of the application's schema. + +## API shape + +```python +# Public API implemented in version 0.2.0. +projection = await context.project_graph( + request, + scope=application_scope, + access=application_access, + semantics=application_semantics, +) + +structured = projection.to_dict() +text = projection.render_text() +mermaid = projection.render_mermaid() +``` + +The request specifies a starting node, relationship direction and type filters, +node predicates, field selection, depth, ordering, and resource budgets. Initial +implementation supports one starting node. Multiple standpoints can follow once +ordering and combined-budget semantics are defined. + +Scope and access are trusted application inputs, not authority supplied by the +model's request. Full-store access requires an explicit application choice. + +This is a bounded library operation, not a general traversal query language. +It does not execute Walker visit hooks or arbitrary model-supplied Python. Existing +query and traversal behavior remains governed by its current public contracts. + +## Canonical result + +The structured representation is the source for every renderer. It includes: + +- Stable node and edge IDs, stored entity discriminators, edge endpoints, and + directed or bidirectional semantics. +- Explicitly selected node and edge attributes, with truncation markers. +- Optional application-provided labels and semantic descriptions, identified as + declarations rather than inferred facts. +- Bounded supporting paths that explain inclusion. The initial default retains + one deterministic discovery path per node; it does not enumerate all paths. +- The starting point, applied filters, scope identifier, ordering, and format + version, without exposing sensitive scope or policy internals. +- Capture time, read interval, and the actual consistency guarantee. +- Completeness relative to the requested view, stop reasons, and optional + continuation information. +- Work accounting available from the backend and the projection engine, with + unknown physical scan costs represented as unknown. + +The initial edge policy is traversal edges: it includes selected relationships +examined during expansion. It does not claim to contain every edge between the +returned nodes. Every emitted edge must have both endpoints in the result. +Authorized frontier entries may indicate further exploration without emitting +dangling edges or revealing inaccessible IDs. + +Text output preserves IDs, relationship meanings, and evidence references in a +compact form. Mermaid output is for inspection and derives from exactly the same +payload. Rendering must escape labels and must never initiate database reads. +Stored content is represented as data; the consuming application determines how +to place that data in a model context without treating it as instructions. + +## Snapshot and continuation semantics + +In the first release, "snapshot" means an immutable captured result. It does not +by itself mean every record was read at one atomic database moment. Results must +label best-effort versus backend-supported consistent reads accurately. + +Subsequent live expansion produces another capture and can observe graph changes. +It must not claim to expand an earlier historical state. A continuation binds to +the request, scope, ordering, and format version, has bounded state and lifetime, +and is validated before use. It must not carry unbounded frontier or visited sets +in a client token. If resumable state exceeds its budget, report that continuation +is unavailable and allow a new bounded query from an authorized frontier node. + +Retained historical generations, cross-request repeatable reads, and incremental +snapshot maintenance are separate future work. Ordinary lifecycle events are +not a durable committed change stream. + +## Resource and access contracts + +Set explicit limits for returned nodes, returned edges, candidate records, +per-node expansion, frontier size, depth, path count, elapsed time, and serialized +bytes. Bound nested objects and list values as well as strings. Token estimates +may be supplied by an optional tokenizer; bytes are the portable output budget. + +Use paged adjacency reads, deterministic ordering, and batched node fetching. +Exact degree counts are optional. Do not inherit entity-name priorities from +the visualization BFS. Application priorities are explicit and must fit the +execution budget; global relevance ranking is outside the initial contract. + +Distinguish engine limits from backend work guarantees. A strict mode may run +only where the selected backend operations support the required execution +controls. Other backends can offer a disclosed scan-based compatibility mode. +No silent full-scan fallback is permitted under a strict work guarantee. +Timeout and cancellation behavior must be qualified for each supported adapter. + +Apply access checks before an entity enters the frontier or contributes to an +exposed relationship, path, count, or summary. Field projection uses allowlists. +Batch access decisions where possible. Denied intermediate nodes cannot serve +as hidden bridges. A budget-exhausted result may contain fewer permitted records +than requested; it must not refill indefinitely. Recheck current permissions +when continuing or exposing cached results, and avoid metadata that reveals +hidden records or counts. + +## Implementation sequence + +1. **Contract and required primitive qualification.** Finalize request/result + models, direction and filtering semantics, capability checks, ordering, + completeness, and consistency labels. Add failing tests for defects in any + existing primitives selected for reuse. Resolve filter loss, unbounded reads, + and graph-boundary behavior on those paths before using them. +2. **Bounded extraction.** Implement the read-only projection operation and + canonical payload. Start semantic tests on JSON; qualify strict execution on + backends with the necessary paged operations. Cover access before expansion, + field selection, paths, cycles, and resource stop reasons. +3. **Views and renderers.** Deliver relationship, hierarchy, and ontology views, + compact text and Mermaid renderers, and bounded progressive exploration. + Reuse extraction results across renderers. Publish API docs, examples, and + explicit backend guarantees together. +4. **Qualification and release.** Measure projection cost, normal CRUD overhead, + and model usefulness. Update PRD, SPEC, stability documentation, public exports, + CHANGELOG, and security-review entries alongside the relevant implementation. + +All three views belong to the initial feature. Broader abstraction through +precomputed summaries, community detection, embedding ranking, retained snapshot +generations, and model-generated inference remains outside this implementation. + +## Acceptance criteria + +- Type, direction, and predicate filters have equivalent meaning on every + supported execution path. Unsupported strict operations fail explicitly. +- Every returned edge has returned endpoints. Shared descendants, self-loops, + cycles, and multiple relationship types preserve their meaning. +- Hierarchy output follows declared relations. A partial exploration never + asserts global absence or complete coverage. +- Denied nodes, edges, and fields do not contribute to visible paths, aggregates, + renderings, or continuations. Permissions are rechecked on continued access. +- High-degree hubs, large frontiers, deeply nested values, and large lists stop + within the advertised engine limits, with appropriate stop reasons. +- Concurrent writes and deleted records yield behavior consistent with the + advertised read guarantee. Captured results remain immutable. +- Query instrumentation separates returned rows, fetched candidates, backend + calls, bytes, and physical scan work where measurable. Test graph growth with + a fixed local neighborhood to identify total-database dependencies. +- Baseline CRUD and ordinary traversal benchmarks quantify overhead with the + feature unused. No performance improvement is claimed from output caps alone. +- On a small fixed evaluation set, compare record-only context with projected + relationship context using the same model and context budget. Measure inference + correctness, evidence-path accuracy, unsupported claims, abstention under + truncation, latency, and context size. Examples include dependency chains, + shared dependencies, hierarchy interpretation, and incomplete evidence. + +## Source findings motivating the plan + +Verified on the baseline commit: + +- `core/graph_expansion.py` loads all incident edges before the BFS edge cap, + computes exact degrees, and can return edges outside its node result. +- `core/entities/node.py` does not forward the requested edge filter in the + `neighborhood` backend-traversal path. +- `db/jsondb.py` loads collection records before applying a query result limit. +- `core/graph_payload.py` leaves lists unbounded during context trimming. +- `db/postgres.py` applies recursive traversal deduplication and result limiting + after expansion; the existing transaction opener does not establish an explicit + repeatable-read contract. +- `core/graph.py` exports through full node and edge collection reads. + +These findings identify qualification work, not permission to change unrelated +public APIs. Reuse and remediation must preserve documented compatibility. + +## Final implementation decisions + +- A separate extraction engine uses raw paged adjacency and batched fresh node + reads. The older visualization/traversal helpers remain unchanged because they + cannot provide this contract without broader compatibility work. +- `native` means backend-side adjacency ordering and row limiting. It explicitly + does not promise bounded physical scan work, query execution, or raw record + size. Compatibility mode discloses scan-based behavior. There is no misleading + strict-work guarantee. +- Results capture best-effort reads. Expansion requests are new live captures + under current scope and access rules. Retained generations, snapshot caches, + and historical continuations are deferred. +- One discovery path per node bounds path growth; other captured edges preserve + cycles and shared descendants. Hierarchy and ontology use the same facts. +- Engine statistics remain host-only, outside model rendering, because rejected + candidate counts could disclose inaccessible cardinalities. Database operations + count abstract adapter calls rather than transport round trips. +- Qualification uses realistic deterministic evidence questions and an independent + traversal oracle.

Index setup is cached per database instance so a second store cannot silently miss a unique index. PostgreSQL integration and transaction cache regressions cover these paths in `tests/db/test_postgres_integration.py` and `tests/core/test_graph_transaction.py`. diff --git a/docs/md/stability.md b/docs/md/stability.md index 1113cb2..0fd021d 100644 --- a/docs/md/stability.md +++ b/docs/md/stability.md @@ -30,6 +30,13 @@ are the canonical import path: adapters must implement `insert_if_absent` or callers hit `NotImplementedError`. - **Cache.** `create_cache`. +- **Graph context for inference.** `GraphContext.project_graph`, + `ProjectionRequest`, `ProjectionScope`, `ProjectionAccess`, + `ProjectionSemantics`, and `GraphProjection` are stable.

Write comparison: 200 simple Object instances. Setup and warm-up are excluded from diagnostic timings; reads have seven samples, writes five. Native write comparisons use pre-exported records, whereas `GraphContext.save_batch` also performs export/cache work.

Effort estimates below are relative, not delivery commitments. + +### F01 — P1: Iterators silently lose rows outside ascending ID order + +**Evidence:** `jvspatial/db/database.py:366–462` and `jvspatial/db/postgres.py:1898–1985`. Both advance with `id > last_id` even when the caller supplies another sort or descending ID. PostgreSQL appends ID to ORDER BY but does not encode the primary sort value into its continuation predicate. + +**Reproduction:** records `a:30, b:20, c:10`, ordered by rank ascending, batch size 1, should yield `c,b,a`; both adapters yield only `c`. Descending ID also yields only `c`. The inherited implementation affects JSON, SQLite, MongoDB and DynamoDB; live reproduction covered SQLite and PostgreSQL. + +**Recommendation:** implement a shared composite cursor using every sort field plus unique ID, preserving directions and missing/null ordering. Until supported, reject unsupported sorts explicitly. Validate positive, bounded batch sizes. `GraphContext.find_page` and the keyset helpers are existing building blocks, but must be parity-tested before reuse. + +**Also:** PostgreSQL holds a pool connection across every consumer `yield`. The live probe shows zero idle connections while a consumer pauses with the only opened connection checked out. Ordinary resumable pages should acquire/release per page; retain a deliberately scoped connection/transaction only for an explicit consistency contract. Add cancellation/early-close tests and pool-wait metrics. Merely enlarging the pool conceals this pressure. + +**Acceptance:** complete, duplicate-free iteration for asc/desc, tied values, null/missing fields, resume, and wrappers; test paused consumers and cancellation. Effort: medium. + +### F02 — P1: DynamoDB partial pushdown drops residual predicates + +**Evidence:** `jvspatial/db/dynamodb.py:929–991`, `1233–1268`, `1322–1348`. `_build_filter_expression` skips unsupported predicates. When any filter expression exists, `find` skips the remaining Python match altogether. + +**Reproduction:** a real adapter with a stub GSI response receives `category=alpha`, indexed `status=open`, and unindexed `score > 50`. It returns both score 1 and score 100. The stub represents valid server filtering of the indexed fields; no AWS service was contacted. + +**Recommendation:** make translation return `(pushed_predicate, residual_predicate)` and always evaluate the residual. Only stop at the requested result count after all predicates pass. Apply the same invariant to scan and GSI paths, across pagination. This is a prerequisite for more aggressive query optimization. + +For performance, add native `LastEvaluatedKey` iteration and key-aware access planning, rather than repeatedly rescanning through the generic ID pager. Distinguish key conditions from filter expressions: AWS documents that filters apply after reads and do not reduce read capacity. [AWS reference](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Query.FilterExpression.html). + +**Acceptance:** mixed indexed/unindexed/operator queries must match the in-memory oracle, including multi-page responses and limits. Measure consumed capacity and scanned/returned counts on live DynamoDB separately. Effort: small/medium for correctness, medium for native iteration. + +### F03 — P1: Cache wrapper can publish failed writes and hide native iteration + +**Evidence:** `jvspatial/db/_cache.py:262–291`, `356–358`; inherited `Database.find_iter`. + +`bulk_save` caches every submitted record after receiving only a success count. JSON can return a partial count, so an unsuccessful write can be returned by a subsequent cached `get`. The diagnostic backend reports zero saved records and no persisted value; the wrapped `get` nevertheless returns the submitted record. + +Separately, `CachingDatabase` has no `find_iter` override. Because the method exists on the base class, `__getattr__` never forwards it. A stub native iterator was called **zero times** through the public factory's cache wrapper. This prevents native cursor/iteration enhancements from reaching cached deployments. + +**Recommendation:** invalidate all attempted IDs for count-only partial-success APIs, or consume accurate per-record outcomes before promoting cache entries. Explicitly forward native iterators with correct generator cleanup. Preserve transaction invalidation and current scope boundaries; do not enable wider caching to mask excess reads. + +**Acceptance:** partial failures never become cache hits; native iterator delegation and cleanup work for cache-only, observe-only, and combined wrappers. Effort: small. + +### F04 — P1: `find_one` is an unbounded read on every built-in adapter + +**Evidence:** `jvspatial/db/database.py:464–477`; `Object.find_one` delegates at `jvspatial/core/entities/object.py:754–788`. Built-ins do not override the base method. + +It calls `find(collection, query)` and takes the first item. Unique indexed matches avoid the worst case, but broad predicates fetch/decode every match. The 20k fixture demonstrated this on two live backends. + +**Recommendation:** pass `limit=1` in the base implementation. Implement early-stop scanning where unsupported-query/JSON fallback paths still materialize everything despite a limit. Preserve ordering semantics; a no-sort first match has no guaranteed stable order. + +**Acceptance:** one returned raw record on pushdown paths, bounded early exit on supported fallback paths, no change to no-match behavior. Effort: small for base fix, medium for scan execution. + +### F05 — P1: Entity batch writes bypass native batch implementations + +**Evidence:** `jvspatial/core/context.py:1749–1847`: Nodes always take serial `self.save`; other entities check the DynamoDB-specific `batch_write` method and otherwise perform serial `db.save`. The generic `bulk_save`/`bulk_save_detailed` capability is unused. + +Additionally, only PostgreSQL overrides `bulk_save_detailed`; JSON, SQLite, MongoDB and DynamoDB inherit the serial base loop at `jvspatial/db/database.py:533–585`, despite having native `bulk_save` implementations. SQLite SQL tracing confirms 200 independent transactions for both context and detailed saves versus one for `bulk_save`. + +**Recommendation:** unify adapter bulk execution and structured per-record outcomes, then route context batches through it by collection. Preserve validation, index preparation, entity-specific save behavior, migrations, cache invalidation, and honest partial-success semantics. Do not replace Node saves mechanically without deciding which lifecycle behavior must run per entity. Use bounded chunk sizes for memory and backend limits. + +**Acceptance:** bounded native wire operations/transactions; full success, duplicate IDs, partial failure, cache updates, and entity hooks match the documented contract. Effort: medium. + +### F06 — P1: SQLite ID pagination misses the existing primary-key index + +**Evidence:** `jvspatial/db/_sqlite_translate.py:93–100`, `283+`; schema at `jvspatial/db/sqlite.py:197–220`; generic find at `660–751`. + +The table already has `(collection, id)` as its primary key. The translator instead generates `json_extract(data, '$.id')`, including a null-sorting expression. The recorded plan uses the collection index and a temporary B-tree for sorting. A physical-column range query uses the primary-key index directly. This is avoidable even before adding application indexes. + +**Recommendation:** map ID filter/sort expressions to the physical non-null ID column consistently, including joined aliases. Verify the adapter's raw-record ID coercion contract first so SQL and returned JSON cannot disagree. Avoid a redundant null discriminator for this guaranteed non-null field. Add plan assertions, not latency-only tests. + +For annotated compound sorts, `create_index` also ignores requested key direction (`sqlite.py:431–435`), and generated null-discriminator ORDER BY terms need matching index expressions. Repair based on actual EXPLAIN plans and workload shapes; retain missing-last behavior. SQLite requires expression/query alignment for expression-index use. [SQLite reference](https://www.sqlite.org/expridx.html). + +**Acceptance:** ID pages use the indexed range without a temporary sort; multi-key mixed-direction and nullable-field plans are checked separately. Effort: small/medium. + +### F07 — P1 for large files: “Streaming” buffers the entire file + +**Evidence:** both `jvspatial/storage/interfaces/local.py:631` and `s3.py:529` call `await asyncio.to_thread(list, _read_chunks())` before yielding. + +This offloads blocking reads but retains all chunks in memory and delays the first byte until the entire object is read. The S3 stub confirms the full read and close before the first yield. Local storage has the same source pattern; no live S3 throughput claim is made. + +**Recommendation:** use incremental worker reads or a bounded producer/consumer queue, preserving backpressure. Close file/body handles in `finally`, including cancellation and consumer abandonment. Benchmark chunk sizes; avoid assuming 8 KiB is optimal when each read crosses a thread boundary. + +**Acceptance:** first chunk arrives before EOF; memory depends on chunk size/queue capacity rather than total file size; abort closes resources promptly. Effort: small/medium. + +### F08 — P2: JSON has repeated full scans, unbounded scheduling, and synchronous metadata I/O + +**Evidence:** `jvspatial/db/jsondb.py:316–350`, `353–384`, `424–473`. `find` and filtered `count` gather all records before matching. Count is described as streaming but holds the complete decoded list. The default iterator repeatedly invokes this full scan: 500 records produced 5,500 load attempts. + +Read helpers also split existence checks and reads into two thread submissions per file (`210–233`). `_get_collection_dir`/`_get_record_path` perform mkdir/resolve and first-use sweep work synchronously when invoked by async read methods (`136–186`, `307–310`). A first-use initialization lock can block the loop while another thread performs the sweep. SQLite also performs synchronous directory creation during connection initialization (`sqlite.py:177–190`). + +**Recommendation:** bounded batches/worker queues, one offloaded open/read/parse operation handling missing-file exceptions, incremental matching, and scan-once iteration. Decide explicitly whether a one-time ID list is acceptable or external sorting/indexing is needed; do not claim constant memory while retaining O(N) paths. Move all filesystem metadata work off the event loop without weakening path confinement, locks, or fsync durability. + +**Acceptance:** O(N) record reads per full JSON iteration; bounded in-flight reads; loop-lag tests under slow metadata/read operations; unchanged crash-safety and path tests. Effort: medium. + +### F09 — P2: Page-number navigation transfers discarded documents + +**Evidence:** `jvspatial/core/pager.py:142–195`. Every numbered page counts all matches, then downloads either the entire prefix to establish an ID pivot or `offset + page_size` full documents for custom sort. The comment “minimal projection” is inaccurate: there is no projection argument in this call. + +**Recommendation:** prefer `GraphContext.find_page` for forward navigation with a qualified composite cursor; make exact counts optional. Keep numbered paging for compatibility but document its cost. Add an explicit raw projection/ID-only API for pivot/export workloads without constructing partially hydrated entities. PostgreSQL/SQLite fallback counts should stream match counters instead of building result lists where native COUNT cannot apply. + +**Acceptance:** forward page work is proportional to page size when indexed; deep numbered pages do not transfer full discarded payloads; count cost is exposed separately. Effort: medium. + +### F10 — P2: Graph expansion bounds output more than database work + +**Evidence:** `jvspatial/core/graph_expansion.py:275–301` loads every incident edge before sorting and applying `max_edges_per_node`. `_node_degrees` at `28–35` then issues one count per returned node using unbounded gather. `expand_node` also requests an exact incident count per page (`137–156`). + +**Recommendation:** implement bounded incident-edge reads with explicit ordering semantics, frontier-batched node retrieval, and grouped degree queries. Preserve existing spine-priority behavior through an explicit generic policy; blindly adding LIMIT before the Python priority sort would change results. Make exact degree/total counts optional when a consumer only needs a page. Keep walker protection and graph reachability invariants intact. + +`GraphContext.nodes_bulk` fallback also fetches all selected neighbor documents before applying node filtering and per-source caps (`context.py:1322–1414`). Push supported predicates earlier and use `find_many` for ID-only lookup. + +**Acceptance:** hub work remains bounded as degree grows; count-query number does not scale one-for-one with returned nodes; same traversal/order semantics. Effort: medium/large. + +### F11 — P2: Fallback execution and observability need explicit budgets + +**Evidence:** PostgreSQL `find` (`postgres.py:964–978`) and SQLite (`sqlite.py:736–751`) materialize a whole collection for untranslatable predicates. Mixed supported/unsupported filters lose all pushdown. `ObservableDatabase` measures adapter calls, not physical wire calls or scanned rows (`_observable.py:109–149`, `420–460`). Its iterator duration includes consumer time across yields. `PerformanceMonitor` retains unbounded event lists (`core/context.py:63–73`), which matters for long-lived contexts. + +**Recommendation:** safe partial pushdown for AND clauses plus residual evaluation, following F02's correctness rule; never push LIMIT ahead of residual filtering or an unsupported sort. Add an opt-in scan budget/fallback-refusal policy and explicit plan metadata. Report execution mode, rows/bytes examined and returned, pool wait, retries, actual statements, and iterator active time separately from consumer time. Use bounded samples/aggregate histograms for long-lived monitoring. + +Keep regex timeouts and all authorization/transaction boundaries. Do not log raw sensitive query values in new metrics. + +**Acceptance:** unsupported predicates are visible, bounded execution is enforceable when requested, metrics distinguish 1 logical bulk call from N wire operations, and long-lived monitoring has bounded storage. Effort: medium. + +### F12 — P1 for measurement confidence: Existing benchmarks obscure query regressions + +**Evidence:** `tests/benchmarks/test_sqlite_benchmarks.py:49–139` includes database setup and 2,000 individual seed writes inside each measured invocation. PostgreSQL benchmarks likewise include connection/setup/seeding (`test_postgres_benchmarks.py:31–72`). This makes them end-to-end setup benchmarks rather than isolated query measurements. + +The benchmark workflow installs `.[dev,test]` (`.github/workflows/benchmarks.yml:68–70`), while asyncpg is in the separate `postgres` extra (`pyproject.toml:63–65`): the service container alone does not ensure PostgreSQL benchmarks execute. The PostgreSQL benchmark helper generates a schema name but never creates it; once asyncpg is available, a fresh schema can fail before benchmarking. It closes the adapter without dropping the schema. The separate hub recorder has different setup and should not be conflated with this helper. + +The PostgreSQL iterator test class is unconditionally skipped (`tests/db/test_cursor_pagination.py:219–232`). The suite passing therefore does not establish F01's iterator correctness. CI comparison currently warns at >25% regression; it is not a performance gate (`.github/workflows/benchmarks.yml:193`). + +**Recommendation:** persistent-loop fixtures seeded outside timing, separate cold/warm measurements, explicit backend extras, safe schema setup/teardown, and a required “expected backend cases executed” check. Restore iterator tests. Add deterministic statement-count and EXPLAIN gates alongside noisy wall-clock comparisons. Measure end-to-end entity APIs in addition to adapters. + +**Acceptance:** query-only measurements react to query changes, no silently absent backend coverage, no leaked benchmark schemas, and correctness/scaling tests cover the defects above. Effort: medium. + +## What is already worth preserving + +- Native `find_many` implementations and context read batching reduce N+1 reads (`context.py:1849+`). +- PostgreSQL COPY-based bulk writes, entity-leading indexes, count/neighbor pushdown, and optional recursive traversal are valuable existing building blocks. +- PostgreSQL/MongoDB/SQLite neighbor joins avoid loading every edge for ordinary `Node.nodes` calls. Existing focused PostgreSQL pushdown tests ran in this audit. +- Edge-derived adjacency avoids rewriting large hub-node adjacency arrays. The historical [hub audit](2026-09-hub-node-baseline.md) is useful prior evidence, not a current-run benchmark. +- Atomic JSON/local writes, per-path locks, bounded regex execution, and context invalidation are correctness constraints for every optimization. + +## Recommended sequence + +| Order | Scope | Expected benefit | Completion criterion | +|---|---|---|---| +| 1 | F01–F03 correctness; restore relevant tests | Prevent silent omissions, excess matches, and phantom persisted records | Cross-backend and wrapper correctness cases pass | +| 2 | F04/F05 bounded first-match reads and true entity batching | Largest directly measured reductions in transferred data and transactions | Row/statement-count gates plus preserved lifecycle behavior | +| 3 | F06/F07 indexed SQLite paging and incremental file streams | Predictable page latency and memory under larger datasets/files | EXPLAIN and streaming/backpressure evidence | +| 4 | F08–F11 scan/graph budgets, projection, telemetry | Lower repeated work and visible degradation paths | Scaling tests and operational counters | +| In parallel with fixes | F12 benchmark repair | Trustworthy regression detection | Expected backend cases actually run | + +Follow-on enhancement: migrate MongoDB's Motor implementation to PyMongo Async with cursor/transaction/reconnect parity tests. Motor's official documentation sets deprecation at May 14, 2026 and critical-fix support through May 14, 2027. As of this audit, that is a maintenance priority; any throughput improvement still requires measurement. [Motor lifecycle reference](https://motor.readthedocs.io/en/stable/). + +Avoid speculative global cache increases, blanket GIN removal, weakened durability, or unbounded concurrent gathers.

The validation below was completed before pull-request preparation; no release or deployment was performed. Existing release-workflow edits were kept separate. + +## Changes by finding + +| Finding | Implementation | Verification | +|---|---|---| +| F01: lost rows / held PostgreSQL connections | Composite cursors include every key, direction and ID; validate batch sizes; typed PostgreSQL numeric/null sorts; per-page pool release; native Mongo cursor cleanup. Existing ID cursors remain usable for ID order. | Ascending/descending, ties, multiple keys, missing/null, resume, numeric values beyond 9, paused consumers; live PostgreSQL and both Mongo drivers. | +| F02: Dynamo residual filters | Re-evaluate residual predicates on every GSI/scan page before limiting. Add unordered `scan_page` with native LastEvaluatedKey, predicate-bound cursor and evaluated-item cap. | Deterministic multi-page GSI/scan stubs, mixed operators, empty matched page with continuation, mismatched cursor rejection. | +| F03: failed writes cached / native iteration masked | Invalidate attempted IDs on errors or uncertain counts; promote only confirmed outcomes; explicit wrapper iterator delegation and cleanup. | Cache-only and combined wrappers, partial bulk failures and native iteration, transaction/cache regressions. | +| F04: unbounded first match | Base `find_one` uses limit=1; JSON/SQL residual matching can stop once the requested match count is reached. | One raw result instead of 20,000; residual early-stop counters. | +| F05: serial entity/detailed writes | Context preparation is shared with individual context saves; chunks of 500 by collection use native detailed writes and preserve success/input ordering. Native JSON/SQLite/Mongo/Dynamo detailed APIs report honest outcomes. PostgreSQL duplicate IDs take the final input, and configured physical vector columns are populated within the batch transaction. | One SQLite commit for 200 entities, duplicate IDs and partial outcomes, mixed collections, transaction-handle routing, pgvector ranking. | +| F06: SQLite IDs / sort indexes | ID translation uses the physical primary key. Retain equality/unique indexes and add companions matching nullable sort expressions, directions and ID tiebreaker. Distinct direction signatures have distinct names; PostgreSQL typed sort companions retain identifier-length bounds. | EXPLAIN uses ID ranges without temporary sorting; mixed-direction, nullable and repeated-direction index setup; live PostgreSQL entity-leading index plan. | +| F07: whole-file buffering | Local/S3 streams bridge one worker read per consumer advance, close in finally and wait for in-flight work before cancellation cleanup. | First read yields a chunk before EOF; backpressure, early close, blocked-read cancellation and invalid chunk sizes. S3 uses a deterministic body stub. | +| F08: repeated JSON scans / scheduling | Single-pass ID iteration, bounded read/save groups (32), streamed count/match, one open/read/parse operation, async-path metadata offloading. SQLite directory creation is deferred to async connection initialization. | 500 files cause 500 loads instead of 5,500; in-flight read cap; existing atomic, confinement and loop-rebind coverage. | +| F09: discarded page payloads / count overhead | Native SQL/Mongo `find_ids` projection with offset; hydrate only chosen IDs. `ObjectPager(count_total=False)` uses lookahead and None totals; keysets remain the forward-navigation API. | Deep-page selected-ID hydration, ordering/null boundaries, filter constraints, count-free navigation. | +| F10: hub loads / per-node counts | Bounded queries for each explicit generic priority tier and ordinary incidents; frontier-batched nodes; grouped SQL/Mongo degrees; optional exact counts. Priority predicates match the opposite endpoint, including when the center shares its prefix. Scheduled nodes stay within max_nodes. Filtered `nodes_bulk` reads push predicates into the node query; plain ID retrieval uses find_many. | Hub transfer cap, priority compatibility and opposite-endpoint regression, grouped self-loop degree parity, count-free expansion and graph traversal tests. | +| F11: fallback budgets / monitoring | Safe conjunction pushdown plus full residual matching; candidate streaming/counting; optional SQL fallback_scan_limit raises rather than truncating. Context-local execution metadata, decoded bytes, PostgreSQL pool wait and retry-driver attempt counts. Iterator active duration is separate from total duration. Diagnostic samples are bounded; counts, means and byte/cache totals remain lifetime aggregates. | Partial AND versus OR/NOT behavior, regex flags retained, early exit / budget rejection / released pool, metadata isolation, retry counts and monitoring retention. | +| F12: benchmark setup / silent service skips | Warm query measurements reuse one loop/store with setup and cleanup outside timing. CI installs the PostgreSQL extra and rejects skipped PostgreSQL cases. Methodology stamp prevents comparison with the old setup-inclusive baseline. | All timed benchmark cases execute; both PostgreSQL cases present and unskipped; workflow YAML / embedded Python validation. | + +The follow-on driver enhancement is available as `create_database("mongodb", ..., driver="pymongo")`. Motor remains the compatibility default. Live tests pass on PyMongo 4.18.2 and the declared minimum 4.13.2. [MongoDB documents the driver differences](https://www.mongodb.com/docs/languages/python/pymongo-driver/current/reference/migration/); no general throughput advantage is claimed from changing drivers alone. + +## Repeated diagnostic results + +The original [baseline JSON](2026-10-10-io-query-audit-results.json) is preserved.

The count of INSERT statements remains 200. +- SQLite ID pagination uses its primary-key range and no temporary sort. +- JSON iteration performs **500 loads for 500 records**, versus 5,500 before. +- The S3 probe reads **one chunk** before yielding, versus 100 chunks plus EOF before. +- Composite/descending probes return all three rows; the Dynamo probe rejects its low-score false match; failed bulk data stays absent from the cache. +- A paused PostgreSQL iterator leaves its pool connection idle. +- Numbered pager probes use the new projection/hydration methods. Their empty `find_calls` list means no calls to the old full-document find path, **not zero database operations**. Native SQL/Mongo still perform projection and hydration, plus an exact count unless disabled. + +These timings are local diagnostics on a busy macOS host, not production p95/p99 or cross-backend rankings. Setup/warm-up are excluded, reads have seven samples and writes five. Export/cache preparation remains included in context save_batch. PostgreSQL qualification used disposable PostgreSQL 16.14 with pgvector; the original audit used PostgreSQL 16.13. Python 3.12.9 and SQLite 3.51.3 were used. Live MongoDB qualification used a disposable standalone 8.0.32 server. + +## Validation + +- Full implementation suite: **2,416 passed, 108 skipped**, with live PostgreSQL/pgvector and MongoDB, including the final priority/direction regressions. Statement coverage: **68.22%** (15,543 of 22,782 statements). The run completed in 301.12 seconds with 109 warnings. +- Focused checks include 149 passing adapter/context/storage tests; another 50 pass with PyMongo 4.13.2, including both live drivers. Final plan/priority checks are also passing. +- Benchmarks: **15 passed, 4 skipped**. Both PostgreSQL benchmark cases executed. The four skips are the separate, untimed hub scale recorder, which pytest-benchmark excludes in benchmark-only mode. +- All configured pre-commit hooks pass on a clean staged-tree snapshot using `pre-commit run --all-files`, including Flake8 plugins, default mypy settings and secret scanning. Workflow YAML and embedded Python compile; git diff whitespace checks pass. +- Commit preparation replaced iterator instrumentation's Python 3.10-only `anext` call with `__anext__`, bound the DynamoDB retry closure explicitly, and completed formatting/docstrings. Follow-up regression runs passed **61 tests (12 service-dependent skips)** and **57 tests** for adapters, bounded queries, observation and streaming. The isolated pre-commit environment avoids the installed pytest syntax issue encountered during earlier manual mypy checks. +- No GitHub Actions, release artifacts or deployment qualification was performed. + +Reproduce against disposable services: + +```bash +PYTHONPATH=. \ + JVSPATIAL_POSTGRES_TEST_DSN="$DISPOSABLE_POSTGRES_DSN" \ + JVSPATIAL_MONGODB_TEST_URI="$DISPOSABLE_MONGODB_URI" \ + pytest -q -o addopts='' --ignore=tests/benchmarks --cov=jvspatial + +JVSPATIAL_POSTGRES_TEST_DSN="$DISPOSABLE_POSTGRES_DSN" \ + pytest tests/benchmarks --benchmark-only + +AUDIT_POSTGRES_DSN="$DISPOSABLE_POSTGRES_DSN" \ + python docs/bench/io_query_audit_20261010.py > new-results.json +``` + +## Adoption notes and remaining qualification + +- `save_batch` now propagates backend exceptions after invalidating attempted identities. It is not atomic across collections. Use graph_transaction where supported, or handle structured partial outcomes/reconciliation. Context saves do not invoke overridden entity.save hooks; applications needing those hooks should call them explicitly. +- Companion indexes consume extra space and add write maintenance. Index creation is idempotent and uses separate names for sort directions; existing equality and unique indexes remain in place. +- JSON keeps O(N) file paths, and custom sorted JSON/unsupported SQL ordering retains matching records. The scan budget is opt-in and counts evaluated residual candidates; it does not constrain a native SQL plan, driver prefetch or DynamoDB scan capacity. +- Native DynamoDB scan_page is unordered. Continue past empty match pages until the cursor is None. Sorted DynamoDB find_iter retains its compatible generic keyset path; use native scan pages where ordering is unnecessary. +- Exact graph counts remain the default and may scan many edges. include_counts=False removes that work and returns unknown values as None. Transfer caps do not imply constant database work without suitable indexes. +- Paging remains live. Mutable sort keys can skip/revisit rows; separate projection/hydration may observe deletes. Use supported transactions or an immutable snapshot for stronger consistency. +- Monitoring's driver attempts, decoded bytes and evaluated candidates are not physical protocol round trips, packet bytes or server EXPLAIN rows. Full transport tracing and sustained production pool/latency histograms need deployment instrumentation. +- Live AWS DynamoDB/S3 capacity, throttling, large-object transfer, long-running concurrency/peak RSS and serverless cold starts remain workload qualification. DynamoDB and S3 correctness tests here use deterministic adapters/bodies. The standalone Mongo tests do not qualify replica-set transactions; topology gating and transaction mocks are covered separately. A default-driver cutover needs downstream qualification and a compatibility cycle. diff --git a/docs/bench/io_query_audit_20261010.py b/docs/bench/io_query_audit_20261010.py new file mode 100644 index 0000000..460da7f --- /dev/null +++ b/docs/bench/io_query_audit_20261010.py @@ -0,0 +1,393 @@ +"""Standalone audit probes; no application data or production services required. + +Run from repository root with PYTHONPATH=. .venv/bin/python . +Optional: AUDIT_POSTGRES_DSN must point to a disposable database; this script +creates and drops its own randomly named schema.

Hosts continue to +own partition membership, current principal permissions, field permissions, +schema definitions, installed application contracts, and model workflows. + +## Verified starting point + +The current public surface and guarantees are in SPEC §6.9 and +`docs/md/graph-projection.md`: + +- `ProjectionRequest` selects fields, types, filters, radius and work/detail caps. +- `ProjectionScope` supplies a trusted flat field allowlist and membership rules. +- `ProjectionAccess.authorize` supplies per-record field grants before expansion. +- `_selected` already supports flat dotted paths and preserves explicit nulls. + A missing selected field is silently absent; clipping yields `truncated_fields`. +- `ProjectionSemantics` supplies string meanings by node/edge discriminator and + label fields. It cannot distinguish semantic roles within one edge class. +- `complete` describes permitted traversal within the radius; `detail_complete` + concerns clipping. Neither evaluates question sufficiency or factual truth. +- Captures are immutable best-effort multi-read results, not atomic generations. + +Primary implementation locations: `jvspatial/core/graph_projection.py`, +`jvspatial/core/context.py`, public exports, and existing projection tests/example. + +## Proposed public contract + +Add an optional trusted keyword argument, leaving existing calls valid: + +```python +await context.project_graph( + request, + scope=scope, + access=access, + semantics=semantics, + context_config=context_config, # new; optional host configuration +) +``` + +Proposed new exported Pydantic configuration types: + +| Type | Purpose | +| --- | --- | +| `ProjectionContextConfig` | Host-selected profile ID/revision and per-node/per-edge type field declarations. No global profile registry or caller-supplied executable configuration. | +| `ProjectionField` | Exact context path, optional label/description/data-type/unit hints, deterministic priority and tighter clipping caps. Hints describe values; they do not coerce or certify them. | +| `ProjectionEvidence` | Optional binding from a projected field to same-record source, observation, verification-state and revision paths. Values are copied as recorded. | +| `ProjectionRelation` | Bounded, application-declared relationship definition with an ID, description, direction wording, optional inverse wording and declarative selectors. | + +Extend `ProjectionSemantics` with optional `relation_rules`, preserving existing +`node_types`, `edge_types` and `label_fields`. Relationship declarations stay in +the existing semantics surface rather than being duplicated in context config. + +Configuration models use `extra="forbid"`, validate duplicate paths/IDs, bound +type/field/rule counts and description sizes, and reject malformed paths, +unsupported predicates and invalid caps. Revalidate and detach nested mutable +inputs before the first await, as the existing capture already does. + +### Field selection and detail + +Field declarations are not permission grants. Effective projection fields are +the intersection of host scope, per-record access, profile selection, and any +explicit request selection. Without a profile, retain today's selection rules. +Requests cannot widen a profile or scope. Explicit empty field tuples retain +their current meaning: no attribute values or field-derived evidence. + +For a configured entity type, its declared paths provide profile defaults. +Unconfigured types retain legacy defaults; hosts can declare an empty profile +for a type to select no detail. Reject configured data/selector/evidence paths +outside the scope before database reads. Per-record grants still narrow them. +Do not support wildcard selection or automatic inclusion of entire containers. + +Keep dotted keys flat. A declaration for `risk.level` never grants its siblings. +Treat parent and child paths as exact grants, not implicit interchangeable +permissions. Preserve null, missing, empty string, zero and false separately. + +Field-specific limits can only tighten global request caps. Apply deterministic +priority ordering with path-name tie breaks in rich mode. Existing canonical +byte, candidate, radius, timeout and nested-value caps remain authoritative. +Richer detail can reduce the topology fitting in a fixed byte budget; report +that honestly rather than promising unchanged topology or raising caps silently. + +### Relationship semantics + +Each rule matches an exact stored edge discriminator and optional predicates on +selected, authorized edge attributes. Optional endpoint selectors may inspect +only selected, authorized attributes of included endpoints. They cause no joins, +extra traversal or schema discovery. Reuse the supported bounded predicate +matcher, including regex timeouts. + +This allows a shared edge class to carry separately declared roles such as +prerequisite, mitigation or alternative without hardcoding those words in core. +Hosts qualify rules using recorded schema identity/revision where necessary; +the framework never derives a meaning from a field name or class-name spelling. + +Zero matching rules means no specialized meaning. Multiple matching rules yield +an explicit unresolved declaration; never choose a rule by list order. When an +input is omitted, denied or truncated, do not resolve a rule from its hidden or +partial raw value. Retain the generic edge-type meaning as a fallback. + +Publish only definitions referenced by emitted relationships, marked +`application_declared`. Do not export the entire host rule catalogue. Preserve +stored edge direction separately from declared inverse wording and traversal +direction. Declared conditions are descriptive data, not executable logic or +claims that the conditions hold. + +### Evidence and freshness + +MVP evidence bindings copy only authorized, selected same-record paths. Source +identifiers are opaque recorded values, not automatic authority or links to +fetch. Related evidence records must enter through ordinary permitted traversal +or a separate host read; a scalar source ID never bypasses endpoint access. + +For each projected fact, include references to its captured record ID and exact +field path, plus whatever source/observation/verification/revision values are +actually present. If an auxiliary path is unavailable, omit its key/value and +use a generic unresolved-evidence marker without naming the unavailable path. +Never manufacture verification, confidence, timestamps, canonical URLs or an +atomic revision. Capture time, record modification time and observation time +remain distinct. An explicitly stored confidence value is labeled as recorded, +not calibrated by the library. + +Initially avoid enrichment callbacks, external lookups and cross-record joins. +The host can already place selected supporting content in bounded fields and +can perform follow-up reads under its own broker and access contract. + +### Coverage and payload versioning + +Default calls continue producing canonical format version 1, with unchanged +field shapes and semantics. A nonempty rich context configuration or relation +rule set opts into format version 2. No existing key is removed or reinterpreted. + +Version 2 adds: + +- Optional profile ID/revision chosen by the host, not a permissions fingerprint. +- Per-record field states for selected AND granted paths only: `present`, `null`, + `missing`, `truncated`. Do not identify denied paths or denied records. +- Authorized field descriptions/evidence and per-edge declaration references. +- Referenced relationship definitions in ontology view, with edge meanings also + available to the other views so choosing a view does not lose matched meaning. +- Coverage metadata stating `requested_radius`, selected-detail coverage, and + `decision_sufficiency="not_assessed"`. The library does not judge whether a + business question can be answered. + +Keep `complete`, `detail_complete`, `stop_reasons`, `truncated_fields`, paths and +expansion points with their existing meanings. No denied cardinalities or +internal work statistics enter model output. Missing detail is not evidence of +absence, and a complete traversal does not certify readiness or global coverage. + +Validate v2 in all renderers. Text output must retain new meaning/evidence/ +coverage rather than silently discarding it. Mermaid can remain topology-focused +with safe labels. All descriptions and stored excerpts remain escaped data, +never model instructions. All metadata participates in exact canonical byte +accounting; final trimming must remove dangling definition/evidence references +and retain closed edge endpoints and valid paths. Expansion requests contain +only request configuration; hosts explicitly resupply context config, semantics, +scope and current authorization for every new live capture. + +## Implementation sequence + +| Step | Owned files/responsibility | Completion criterion | +| --- | --- | --- | +| 1. Lock contract with tests | New `tests/core/test_graph_projection_context.py`; existing legacy tests | Specify v1 parity, rich schemas, missing/null distinctions, denied selectors/evidence, ambiguous rules and byte-limit closure before implementation. | +| 2. Add typed configuration | `core/graph_projection.py`, `core/context.py`, `core/__init__.py`, top-level `__init__.py` | Optional keyword forwarding, detached validation, bounded declarations, exported public types; old calls unchanged. | +| 3. Implement safe detail and evidence | Capture selection/clipping internals, field authorization intersections | Per-type defaults and tighter caps; metadata only from authorized selected data; no additional DB operations for same-record enrichment. | +| 4. Implement relation meanings and v2 | Semantics resolution, finalization and renderers | Deterministic selectors, no hidden/partial-value inference, referenced definitions only, exact byte enforcement and valid trimming. | +| 5. Qualify realistic fixtures/performance | Existing projection example/benchmark and new tests | Correct current, missing, stale and conflicting recorded facts; revocation and partition isolation; measured capture/render/payload overhead. | +| 6. Document and downstream trial | SPEC §6.9, PRD §3/§7, stability doc, core README, projection guide, docs index, CHANGELOG Unreleased | Explicit public contract, migration example, backend caveats and independently attributed deterministic versus model evidence. | + +Implementation should start on an isolated `codex/rich-graph-context` branch +based on the then-current `dev`; inspect the diff from this baseline first. +Do not modify the active dev checkout or unrelated release work. Feature work stays under Unreleased. The user subsequently authorized committing +and pushing these qualified changes to dev; versioning, publishing and deployment +remain separate. + +## Validation matrix and gates + +1. **Compatibility:** all existing projection tests; v1 fixture parity for + structured JSON, text, Mermaid, fingerprints and expansion requests under a + frozen clock. Test all views and top-level public imports. Rich config is + immutable/detached and rejects unknown keys. +2. **Authorization:** independent entity and field denial; hidden intermediary; + readable foreign-partition endpoint; inaccessible evidence and selector + fields; same field key in two schema namespaces; revocation between captures; + policy exceptions and cancellation. No unauthorized value, path, rule ID, + evidence reference, count or sibling field reaches output or renderers. +3. **Correctness:** false/zero/null/missing, nested fields, multibyte strings, + unsupported/nonfinite values, duplicate declarations, conflicting rules, + direction/inverse wording, custom entity discriminators, stale source data, + conflicting stored observations, cycles and shared descendants. Recorded + provenance does not certify truth; conflicts remain visible facts. +4. **Budgets:** every existing cap with rich metadata enabled; tiny-byte captures; + clipped selector values; definition/evidence overhead; no dangling references + after trimming; selected-field states cannot escape caps. Descriptions and + evidence counts are bounded before serialization. +5. **Backends:** JSON first; SQLite and disposable PostgreSQL native captures; + MongoDB when available; compatibility/native rejection contracts for remaining + adapters and wrappers. No database ABC change is expected. Adapter tests + must verify no unscoped full graph export was introduced. +6. **Performance:** compare legacy versus configured rich capture at 100/1,000 + candidate budgets and sparse/high-degree fixtures; report warm median/p95, + DB operations, canonical/rendered bytes and clipping rates. Same-record + enrichment must add zero DB operations versus equivalent plain field + selection. Reject unexplained repeatable >20% median capture overhead versus + an equivalent-field baseline; establish a repeatable baseline before judging. + Raw record size, physical scans and downstream model tokens remain separate. +7. **Repository gates:** focused tests, `pytest -q`, coverage suite, pre-commit + all-files, and projection benchmarks. Run console `pytest` as well as the + focused module invocation where source-import behavior matters. Document + unavailable infrastructure rather than treating skipped tests as qualification. + +Acceptance fixture: a rooted project has two prerequisites, one mitigation and +an unverified alternative. Record a due date, operational state, evidence source, +observation date and schema-qualified relationship meanings. Include missing, +stale and conflicting evidence variants plus denied and foreign-partition links. +Deterministic tests must prove the exact authorized facts and limits in every +variant. A downstream model trial must separately score supported conclusions, +relationship direction, mitigation scope, honest unknowns and evidence citations +under a fixed prompt/model/budget. The library tests do not claim model quality. + +## Risks and deliberately deferred work + +- Rich content increases prompt-injection exposure and payload size: preserve + data encoding, explicit field selection and limits; host prompts enforce the + distinction between instructions and captured data. +- Semantic selection can leak hidden attributes: evaluate only selected, + authorized, untruncated inputs and publish referenced declarations only. +- Same-record evidence is deliberately limited. Add an async batch enrichment + protocol only after a measured use case requires it, with separately specified + authorization, timeout, source closure and per-call budgets. +- Persistent generations, atomic snapshots, relevance-ranked traversal, logical + inference and automatic constraint/readiness evaluation are separate projects. + Record revisions are useful evidence, not a replacement for atomic reads. +- Existing PRD/ROADMAP statements outside projection contain historical drift. + Trust source for this plan; update projection contracts with code and avoid an + unrelated documentation rewrite. + +## Definition of done + +Legacy users see no changed defaults. Opted-in hosts can configure useful facts, +field-level evidence and qualified relationship meanings without weakening scope +or access. Rich output describes exactly which authorized detail was captured, +what was clipped/missing, and what the library cannot certify.
