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.
Add an explicit tenant lifecycle (active/retired), allow-listed mutable
metadata, record versioning, and lifecycle timestamps to the tenant authority.
- domain: TenantLifecycle, with_metadata/retire/reactivate, immutability and
transition invariants. Identifier stays immutable -- it is the IAM Profile
`tenant` claim key-cape mints into tokens.
- store: mutate_tenant() commits idempotency replay, version CAS, mutation,
and audit event together; durable receipts survive restart. Retired tenants
refuse new grants and plan changes but keep their history.
- sqlite: forward-only idempotent migration; existing rows default to active
at version 1. Reads now take the write lock -- the concurrent-writer test
caught unguarded reads on the shared connection observing mid-transaction
state as a spurious tenant_not_found.
- api: GET/PATCH /tenants/{id}, POST retire|reactivate. Idempotency-Key and
If-Match required, distinct flex-auth actions per operation, stable error
schema, redacted 503s.
- docs/tenant-lifecycle-api.md: consumer contract for user-engine.
Implemented against SQLite, not PostgreSQL as the workplan assumed --
TEN-WP-0004 shipped SQLite on a PVC as the production store.
124 tests pass (was 66); no breaking change to existing endpoints.
