A production rollout exposes a contract mismatch between the UI boundary and the owning service. The affected area is job queue.
Repair the job queue tests implementation so it classifies stable, flaky, and consistently failing tests from repeated independent runs.
Evidence
- Affected surface: Full-stack backend focus / job queue.
- Observed failure family: triage an unreliable test suite.
- Scope policy: zoneState must equal healthy.
