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.
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.
Adds Core-owned identity contracts, a Core-owned Better Auth database schema
(ekklesia_core_user/session/account/verification), a first-class Core-owned
migration source that coexists with module-owned migrations under the exact
existing migration system, and an explicit Better Auth construction boundary.
No authentication endpoint or sign-in UI is exposed yet (ADR 0010).
