-Fresh live flex-auth -> access-engine preflight returns exactly the
-`preflight_signing_unavailable` blocker. Target is primary/railiance01,
-namespace/release/deployment state-hub, current API SA state-hub and one replica.
-After platform custody verification, enable the chart, prove API-only delivery,
-all-replica key equality, health and non-mutating signed preflight. Then stop all
-API replicas (including terminating pods), rotate with CAS through platform,
-wait ESO, restart and prove predecessor invalidation and forward recovery.
