Central was serving two revisions behind the code it shipped: review_contracts did not exist there although its migration was inside the running image. There was no migration mechanism at all — bare uvicorn CMD, nothing chart-declared — and nothing surfaced the mismatch. The API starts happily against a schema it was not built for and only fails when a request touches a missing table. Adds a chart-managed Helm pre-install/pre-upgrade hook running alembic upgrade head, weighted to complete before the API rolls. A hook rather than an init container: init containers run per pod, so more than one replica means concurrent alembic upgrade with no locking. Failed jobs are deliberately retained — a migration that fails and vanishes is how this drifted in the first place. /state/health now reports applied and expected revisions. "unknown" is deliberately not "ok": an instance that cannot establish agreement must not claim it, the same principle as instance_role defaulting to unknown.
