A cross-layer workflow passes unit tests but breaks when client, API, and persistence state arrive in a different order. The affected area is session boundary.
Repair the session boundary dependency protection implementation so it opens only after the failure threshold and calculates a deterministic retry time.
Evidence
- Affected surface: Full-stack frontend focus / session boundary.
- Observed failure family: calculate circuit-breaker state.
- Scope policy: authorized must equal true.
