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.
Wires Core's identity and authorization domains into apps/api over one
shared, validated PostgreSQL pool; adds an explicit, single-use,
concurrency-safe platform-owner bootstrap CLI; adds a smallest-possible
immutable permission registry with one Core-owned restricted permission
(core.authorization.grants.manage); and adds reusable Hono authorization
enforcement plus a narrowly scoped /api/v1/grants HTTP API for managing
explicit grants only, gated by an exact trusted Origin on every mutation.
