A cross-layer workflow passes unit tests but breaks when client, API, and persistence state arrive in a different order. The affected area is migration rollout.
Repair the migration rollout dependent jobs implementation so it produces a deterministic dependency order and reports blocked cyclic work.
Evidence
- Affected surface: Full-stack backend focus / migration rollout.
- Observed failure family: order dependent work.
- Scope policy: qualityState must equal verified.
