A cross-layer workflow passes unit tests but breaks when client, API, and persistence state arrive in a different order. The affected area is service gateway.
Repair the service gateway activity stream implementation so it splits activity after the configured inactivity gap and counts sessions per actor.
Evidence
- Affected surface: Cloud-native full-stack / service gateway.
- Observed failure family: sessionize event activity.
- Scope policy: tenantId must equal tenant-primary.
