fix: enforce explicit grant invariants
Explicit-grant management could produce states an operator could not reason about, and pushed request-shaped problems into the database. Two identical createGrant calls produced two grants; five concurrent identical calls produced five. Revoking one returned success while the equivalent kept authorizing the same user — an operator could believe they had removed access that was still live. Two issuances are now the same authorization source when user_id, permission_id, scope, source_kind, and source_ref are all equal, with NULL equal only to NULL; expiry, creation metadata, actor, and grant id do not distinguish them. Creating one while an equivalent is currently effective fails with AUTHORIZATION_GRANT_ALREADY_EXISTS (HTTP 409, no-store) naming nothing about the grant that already exists, and writing no grant and no audit row. A revoked or expired equivalent does not block a fresh issuance. Conflict rather than idempotent return: the caller asked to record a new authorization with their own actor and expiry, and answering "done" while recording neither would hide that nothing happened. Enforcement is database-backed, since nothing constrains the number of API processes: every create and revoke touching one equivalence tuple takes a transaction-scoped advisory lock keyed by a hash of that tuple, encoded as a JSON array so NULL stays distinct from the empty string and a crafted scope cannot forge a separator. A collision can only make unrelated tuples serialize, never hide a conflict, because the decision is always an exact SQL predicate. Its single-key lock space is verified disjoint from the two-key space the migration runner and bootstrap use. A time-dependent partial unique index was rejected: now() is not immutable and cannot be indexed. One revocation now clears every unrevoked equivalent — including expired-but- unrevoked legacy rows, so the history is left in one state — with one audit row per grant actually revoked, each carrying its own id, in one transaction. Differently scoped or sourced grants are untouched. Historical duplicates are not silently revoked by migration; the store prevents new effective equivalents and an operator's explicit revocation resolves the class. The request boundary no longer leaks into PostgreSQL. GrantId accepts exactly the canonical lowercase hyphenated UUID the database emits, with no trimming and no case folding, so a malformed path parameter is a 400 decided after authorization but before any store call instead of reaching the UUID comparison and returning an indistinguishable 503; a canonical unknown id still returns 404. expiresAt accepts exactly YYYY-MM-DDTHH:mm:ss.sssZ, byte-for-byte equal to the parsed date's own toISOString, and must be strictly future — bare new Date silently rewrote 2026-02-31 to March 3rd and accepted locale, date-only, offset, and millisecond-free forms, and a past expiry was stored as a grant dead on arrival. The store validates the same thing before any SQL so trusted internal callers get the guarantee too. The generic HTTP surface now rejects a scope field in every form, including null. No route middleware supplies a scope to the evaluator, so a scope accepted here produced a grant that persisted, listed, and authorized nothing. Core's scope semantics are unchanged for internal callers; no resolver was added. Listing was unbounded and returned a user's entire history. It is now keyset pagination over created_at DESC, id DESC with a strict boundary on both values, so rows sharing a timestamp are neither skipped nor repeated, at most limit + 1 rows read, explicit-source filtering server-side on every page, and an opaque unsigned position cursor that is strictly decoded and reveals nothing on rejection. Core's list method requires a validated finite bound with no unbounded fallback anywhere. Co-Authored-By: Claude Opus 5 <[email protected]> |

docs: record module authorization architecture
Adds ADR 0014 recording the durable architecture Phase 5A established across both passes: the shared contracts-layer PermissionDeclaration, manifest version 3 replacing version 2's bare permission strings, the reserved core.* namespace and the structural guarantee that a module-vs-Core collision always surfaces as ModulePermissionCompositionError rather than the generic PermissionRegistryError duplicate path, deterministic registry composition, startup ordering, repository-root/package-version resolution, registry injection into apps/api's enforcement and explicit-grant HTTP API, the static-snapshot/historical-record preservation guarantees, and Doctor/modules:validate integration. Indexes it in the ADR README, cross-references it from ADR 0006 (only its manifestVersion 2 / permission-string decision is superseded; the rest of ADR 0006 remains accepted, and its historical text is left untouched) and ADR 0013 (module permission registration, deferred there, is what ADR 0014 implements), and links it from the relevant development documentation. Corrects two comments discovered during a direct source audit that overstated where a module-vs-Core permission collision is actually caught (core/src/modules/permissions.ts, apps/api/src/platform-permissions.ts) — comment-only, no behavior change, already covered by existing tests. Also corrects a documentation claim in docs/development/authorization.md that incorrectly implied removing a module blocks explicit revocation of its historical grants; grants-routes.ts's revoke handler never consults the permission registry, so revocation remains unaffected. |

fix: enforce registered authorization permissions
Two related fail-closed gaps let a well-formed but never-declared permission id slip through: - POST /api/v1/grants created explicit grants for any well-formed PermissionId without checking the injected permission registry, allowing dormant grants for invented identifiers that could become effective the moment those identifiers were registered later. - createAuthorizationEvaluator validated the permission id only inside the restricted-baseline branch, so a malformed permission combined with the public or authenticated baseline could still return allowed. Both now fail closed: the grants route checks the target permission against the trusted registry before calling store.createGrant (sanitized 403, no store or audit write), and the evaluator validates permission shape before any baseline is allowed to return an allowed decision, without adding a registry dependency to the evaluator itself. The live integration lifecycle test switched from an unregistered calendar.events.read to the registered core.authorization.grants.manage permission, since module permission registration does not exist yet. |

docs: record core authorization architecture
Adds ADR 0013 documenting the durable Phase 4C decisions (permission registry, evaluator baselines, grant/scope semantics, platform-owner bootstrap, shared database pool, Origin enforcement, and what remains deferred), cross-links it from the authorization/README docs, and refreshes the pnpm doctor no-DATABASE_URL example output in README.md and repository-workflow.md to include the authorization migration. |
