A production rollout exposes a contract mismatch between the UI boundary and the owning service. The affected area is resilience policy.
Repair the resilience policy activity stream implementation so it splits activity after the configured inactivity gap and counts sessions per actor.
Evidence
- Affected surface: Cloud-native full-stack / resilience policy.
- Observed failure family: sessionize event activity.
- Scope policy: contractVersion must equal 2.
