 ## Test Scenarios
 
-1. **Happy Path**: Valid checksums, successful update
+> **Note:** The comprehensive Playwright update specs were removed on 2025‑11‑12 after repeated
-2. **Bad Checksums**: Server rejects update, UI shows error once (not twice)
+> release-blocking flakes. We now rely on:
-3. **Rate Limiting**: Multiple rapid requests are throttled gracefully
+>
-4. **Network Failure**: UI retries with exponential backoff
+> 1. `tests/00-diagnostic.spec.ts` — ensures the containerized stack boots and the login page renders.
-5. **Stale Release**: Backend refuses to install flagged releases
+> 2. `tests/integration/api/update_flow_test.go` — drives the `/api/updates/*` endpoints directly to
-
+>    verify the backend can discover, plan, apply, and complete an update.
-## Frontend Validation
+>
-
+> Reintroduce full UI coverage once we have deterministic fixtures and selectors for the update flow.
-- UpdateProgressModal appears exactly once
-- Error messages are user-friendly (not raw API errors)
