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).

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).

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.

(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`). The redirect cannot bypass the ceiling — + it never reaches code issuance. POST `/authorize` keeps the raising + `Depends(get_current_user)`; only the GET seam is non-raising. ✅ +- New access-token revocation is NOT a DoS / arbitrary-denylist surface: Authlib's + `authenticate_token` enforces `authenticate_endpoint_client` then + `token.check_client(client)` *before* `revoke_token`. `_RevocableAccessToken.check_client` + compares the token's `client_id` claim to the authenticated client, AND the token + string must verify as a valid, non-expired, audience-bound JWT. A caller can only + denylist a jti for a token issued to their own authenticated client that they + physically present. ✅ + +### V5 — Deferred items are genuinely deferred, not half-done + +- **Item 5 (RFC-8707 per-request resource → aud):** `aud` is consistently the + `issuer` (single-resource). `routes.py` builds the server with `resource=issuer`; + `JvSpatialJWTTokenGenerator.get_audiences` returns `self._resource` (= issuer) for + every token; RS verification (`resource.py`, `auth_middleware`) and the revocation + path all check `audience=issuer`. There is NO partial per-request resource + variation — the seam (`_resource` field, `get_audiences` hook) exists but is + uniformly wired to the issuer. Clean. ✅ +- **Item 7b (trusted XFF):** XFF is NOT trusted. `_get_client_identifier` uses + `request.client.host` (the immediate socket peer) only; the only `X-Forwarded-For` + references in `rate_limit.py` are the comment explicitly stating it is deferred and + NOT parsed. No spoofable header feeds the bucket key.

Security verdict + +**SAFE TO MERGE.** The headline scope-ceiling fix composes correctly across all +branches with no over-grant; the DCR and authorize ceilings share one source of +truth; every failure mode (CAS lost race, denylist DB error, missing backend, +scope edges) is fail-closed; the only two behavior changes for an unconfigured +consumer are the documented `[]`⇒deny footgun fix and the strictly-more-protective +IP-only rate-limit key; no M4 change weakens another auth path; and the two +deferrals are uniformly absent rather than half-implemented. + +### Cross-repo verification (integral consumer, editable install) + +The full test verification (separate from the security pass) ran both repos. **jvspatial:** oauth slice **74 passed**, middleware green; only the pre-existing `tests/storage/*` libmagic/MIME failures remain (M4 touches no storage code). **integral:** the test run initially FAILED — 2 consent escalation tests over-granted `admin` — because integral's *separate* consent authorization-server (`backend/app/api/oauth_consent.py`) was built without declaring `supported_scopes`, so M4's new `'*'`-wildcard branch (which is *meant* to be bounded by the supported-scope ceiling) had no ceiling to apply on integral's path. This is the exact composition gap the security pass could not see (it reviewed jvspatial's flow where the ceiling is declared). **Fixed integral-side** in commit `1bb5f5a` (`feat/m3-agents-ui`): the consent `_AS` now passes `supported_scopes=settings.OAUTH_SUPPORTED_SCOPES` (`["integral"]`), parity with the mounted server. **Post-fix: integral consent 10 passed, broad oauth/mcp slice green, boot OK.** Lesson: any consumer that builds its own `build_authorization_server(...)` instance MUST declare `supported_scopes` to get the M4 ceiling — the `'*'` branch is unbounded without it. Both repos now green. + +- **Critical:** none. +- **Important:** none. +- **Minor (benign, surfaced in per-task reviews; documented, not blocking):** + - *jti denylist duplicate-row idempotency:* `revoke_jti` does a read-then-insert + (`find` → insert if absent), not an atomic upsert; two concurrent revocations of + the same jti could in principle write two rows.

Documented deferrals (intentional, not skipped) + +### Item 5 — RFC-8707 per-request resource → token `aud` + +**Status:** deferred. **Why it's correct to ship without it:** the AS and RS are the +same process and serve a single protected-resource audience, so binding every token's +`aud` to the `issuer` is the correct single-resource behavior (`aud == issuer`), +verified consistently on issue and on validation. **When to implement:** when jvspatial +serves *multiple* resource-server audiences from one AS (a client requests a token for +a specific RS via the `resource` parameter, and the token `aud` must reflect that RS, +not the issuer). **Seam already present:** `JvSpatialAuthorizationServer._resource` is a +distinct field and `JvSpatialJWTTokenGenerator.get_audiences(client, user, scope)` is the +override point — implement per-request `resource` parsing there and thread the requested +resource through the grant. 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.

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).

Dependency is now `starlette>=0.46.0`. jvspatial's lifecycle hooks use its own `LifecycleManager` (FastAPI lifespan), not the `Router(on_startup/on_shutdown)` API removed in Starlette 1.0, and route introspection is version-agnostic (see the `iter_api_routes` fix below). Verified against Starlette 1.3.1. +- **Redis cache no longer unpickles untrusted blobs in the default JSON mode** (`jvspatial/cache/redis.py`). Previously, an unprefixed value in `json` serialization mode fell through to `pickle.loads`, so anyone able to write to the Redis keyspace could achieve remote code execution even with the "safe" default. JSON mode now refuses non-JSON values (treated as a cache miss → recompute). Legacy pickle entries are readable only when explicitly opted in via `allow_legacy_pickle=True` / `JVSPATIAL_REDIS_ALLOW_LEGACY_PICKLE=true` on a trusted keyspace. Explicit `pickle` mode is unchanged. + +### Fixed + +- **Starlette ≥ 0.52 compatibility: included routes became invisible to auth/OpenAPI introspection.** Newer Starlette wraps `app.include_router(...)` results in an `_IncludedRouter` object instead of flattening `APIRoute`s into `app.routes`. jvspatial's auth resolver only inspected top-level `APIRoute`s, so included routes (e.g. file-storage endpoints) were treated as unregistered and denied by default (spurious 401s); OpenAPI security/padlocks were also dropped. Added `jvspatial/api/_route_utils.py::iter_api_routes` and routed all route-table introspection through it (auth resolver, OpenAPI security wiring, dynamic-walker registration, duplicate-route detection). Works across old and new Starlette. +- **Docs: authentication examples used a flat `auth_enabled=True` kwarg** that `ServerConfig` silently ignores (auth stayed disabled). Corrected README and `docs/md/{authentication,api-keys,migration}.md` to the nested `auth=dict(...)` form. +- Layered cache fell back to `print()` for Redis-unavailable warnings; now uses `logging.warning` (`jvspatial/cache/layered.py`). + +### Packaging + +- Removed `setup.py`; `pyproject.toml` is now the single source of build metadata. Version resolves dynamically from `jvspatial/version.py` via `[tool.setuptools.dynamic]`. Fixes a metadata conflict where the wheel published `Requires-Python: >=3.8` while the project targets `>=3.9`. +- Added the `cache` extra (`redis[hiredis]`) so `pip install jvspatial[cache]` works; it backs `jvspatial.cache.redis`. +- Completed the `all` extra to cover every runtime-optional backend/feature (lambda, postgres, pgvector, otel, cache, scheduler). +- Removed the redundant top-level `requirements*.txt` files; dependencies live solely in `pyproject.toml` extras. + +### Phase F — Cursor pagination (2026-05-26) + +#### Added + +- **`Database.find_iter` async iterator** (`jvspatial/db/database.py`): constant-memory pagination across all backends. 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).
