TEN-WP-0005 landed the authoritative metadata update and reversible
retirement contract, so USER-WP-0021-T01's deferred tenant operations are
now implementable without user-engine inventing lifecycle semantics.
TenantManagementPort gains read, update, retire, and reactivate. The HTTP
adapter echoes the record version as an If-Match ETag (never `*`), sends an
Idempotency-Key plus actor/reason/correlation_id, and surfaces
Idempotent-Replay. Authority failures map to redacted domain errors carrying
only the contract's stable error_code; its detail text never crosses the
boundary.
Platform operators get the matching API routes and a CSRF-protected browser
screen that reads the record before mutating it and hides the metadata form
for a retired tenant. Portal OpenAPI moves to 0.3.0 with TenantRecord,
UpdateTenant, and TenantLifecycleChange.
Full suite: 145 tests, 3 external-provider skips.
