Implements the four residual conformance checks left open by the T04
minimal vertical:
- C2: GET /ports/registry/registrations/{hub_slug} resolves missing (404),
ambiguous (shared reuse_surface_id across hub_slugs), and stale
(deprecated/retired descriptor) registrations; a new .../audit route
exposes queryable registration history from the existing in-memory
history and the PostgreSQL runtime_audit_ledger.
- C7: harness proof that disabled compatibility groups deny access
(404) with no fixture credentials involved, matching the existing
fail-closed compat router behavior.
- C9: harness proof plus a dedicated test that /readyz degrades only on
an unavailable configured dependency while unrelated disabled
projections stay non-blocking.
- C10: ContractValidator now negotiates contract_version_min/max against
the runtime's contract version and rejects incompatible or inverted
ranges with an explicit 422 instead of silently accepting them.
HUB-WP-0009 is now finished. HUB-WP-0006 is marked blocked: its only open
task (T06) has no remaining hub-core code path and waits on an external
Forgejo identity/production deployment gate. HUB-WP-0011 is marked
blocked: T02/T03 already waited on external credential/deployment
review, and T01 needs a source/destination ownership and retention
decision against live message data before it can be implemented safely.
