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