A distributed workflow needs a localized repair without weakening observability or rollback safety. The affected area is dashboard aggregation.
Repair the dashboard aggregation command handling implementation so it accepts first operations, recognizes safe repeats, and rejects key reuse with a different payload.
Evidence
- Affected surface: Full-stack frontend focus / dashboard aggregation.
- Observed failure family: enforce idempotent operations.
- Scope policy: retained must equal true.
