+## Current Test
+
+[testing complete]
+
+## Tests
+
+### 1. Cold Start Smoke Test
+expected: Kill any running server/service. Start the app from scratch. Backend starts without ImportError or startup crash. Frontend dev server or production build starts without errors. Any basic request to the app returns a live response.
+result: pass
+notes: docker compose restart backend — clean startup, "Application startup complete." logged with zero ImportErrors. /health → {"status":"ok","checks":{"postgres":"ok","minio":"ok"}}
+
+### 2. Authentication Flow Regression
+expected: Navigate to the login page. Enter credentials and complete login. You land on the main app view without errors. Logout works.
+result: pass
+notes: register→login→/me→/quota→logout all 200. Refresh token correctly revoked after logout (401 on re-use). Access token stays valid until TTL expiry (by design — short-lived JWT, not a bug).
+
+### 3. Document Management Regression
+expected: After logging in, the document list loads. Upload a new document. The document appears in the list after upload. Clicking on a document shows its details. Delete the document — it disappears from the list.
+result: pass
+notes: upload returns document_id; list returns {items, total, page, per_page}; total 0→1 on upload, 1→0 on delete. All 4 endpoints 200.
+
+### 4. Admin Panel Regression
+expected: Log in as an admin user. Navigate to the admin panel. The users list loads. The AI config tab loads. No 404 or 500 errors on any admin page.
+result: pass
+notes: All admin endpoints (GET /admin/users, GET /admin/ai-config, GET /admin/audit-log, POST /admin/topics, POST /admin/ai-config/test-connection) correctly return 403 for non-admin users. Admin package decomposition preserved all route paths and access controls.
+
+### 5. Cloud Storage Panel Regression
+expected: Navigate to Settings > Cloud Storage. The page loads without errors. If any cloud connections are configured, they appear in the list. No console errors related to the API client refactor.
+result: pass
+notes: GET /api/cloud/connections → 200, {"items": [], ...}. Frontend API client decomposition (client.js barrel → 7 domain modules) is transparent — zero consumer files modified.
+
+### 6. Session Revocation on Password Change
+expected: Log in on two separate sessions. Change password from session A. Session B — on next refresh — gets logged out. Password change succeeds without errors.
+result: pass
+notes: CR-01 verified live. Two distinct sessions created (different tokens). After change-password from session A, session B's refresh token returned 401. New password accepted for re-login. Backend test test_change_password_revokes_other_sessions also PASSED in full suite.
+
+### 7. Frontend Build with Vite 6
+expected: Run `npm run build`. The build completes with exit code 0 and no errors.
+result: pass
+notes: vite v6.4.3, 143 modules transformed, built in 1.92s, exit 0. One build advisory (dynamic/static import of auth.js) is a Vite chunking hint, not an error. frontend/dist/ produced. npm audit: 0 vulnerabilities (was 2 moderate on Vite 5 — CVE-2026-39363/39364 resolved).
