Engine/PIP declaration is now checkable (layer.yaml plus a Tooling-client
scan). Writes persist a decision record or the published fail-closed
stance, live-lookup freshness is published, events_for is tenant-scoped,
and mutation evidence drains to audit-core from a local outbox without
blocking the mutation.
Sender registration is requested as AUDIT-IN-0002. Boundary-contract
amendment is requested as NET-IN-0002.

Add the PostgreSQL backend, migration and stopped-write transfer tools, lease-aware deployment manifests, tenancy declarations, and shared conformance coverage. Persist grouping mutations in durable stores and separate process liveness from database readiness.
