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