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 request stream implementation so it enforces a per-key sliding window and reports allowed and rejected requests.
Evidence
- Affected surface: Cloud-native full-stack / service gateway.
- Observed failure family: apply a sliding rate window.
- Scope policy: tenantId must equal tenant-primary.
