-- `src/api/dashboardApi.test.ts`: endpoint path/query composition and payload mapping.
+- `src/api/dashboardApi.test.ts`: endpoint path/query composition for board and operator action flows.
 - `src/auth/oidcLogin.test.ts`: OIDC start-url generation and safe return-url fallback.
-- `src/App.test.tsx`: central login screen, protected board flow, and priority update workflow.
+- `src/App.test.tsx`: central login screen, board lane loading, operator actions, and session-expired reauthentication guidance.
 
 ## Notes
 
 - Use containerized Node execution when host `npm` is unavailable.
+- Prefer container-first validation before opening or updating runtime stack images.
