A cross-layer workflow passes unit tests but breaks when client, API, and persistence state arrive in a different order. The affected area is checkout journey.
Repair the checkout journey dependency health implementation so it derives overall health from critical failures, latency, and degraded dependencies.
Evidence
- Affected surface: Balanced full-stack / checkout journey.
- Observed failure family: summarize dependency health.
- Scope policy: region must equal eu-west.
