 - Real backend like/unlike returned 200/200; isolated profile identity was restored to original false/count. Personalized reload returned active state. Explicit browser 403/aborted and late-response fixtures tested recovery without repeated toggle or expired UI resurrection. Guest/expired protected requests: zero.

+- Actual process-output screenshots: .codex/story-4/evidence/passing-tests.png and passing-tests-coverage.png, with corresponding .txt logs. These display captured command stdout/stderr, timestamps and exit codes; they are not simulated terminal output. Both commands exited 0, all 133 tests / 16 suites passed. Coverage: statements 47.21%, branches 49.94%, functions 43.24%, lines 46.94%.
+- All six required verification commands passed. Additional real Firebase regression: signUp/update/signIn 200, wrong-password signIn 400, recovery 200; isolated test account deleted. Original Batch 1 authentication evidence files were refreshed locally but Task 6 evidence is test output. CI verification pending PR creation.

 - PR #38 merged at 845c4ce. Auth guard branch created from updated story-4; valid users blocked for UI/direct/history entry via replaceState.

Browser direct/UI/Forward guard and Guest Back/Forward Details/Auth restoration passed.
 
 - PR #39 merged at af700b4. Favorites implemented with personalized GET, exact guarded POST, pending lock, confirmed response state/count, read-only reconciliation after unknown outcomes, stale-session rejection. Fixed erasableSyntaxOnly class syntax and inactive feedback display; all checks passed (105 tests, 39.59%). Browser real add/remove returned 200 and restored isolated identity favorite to false; injected 400 and lost response verified recovery, Guest/expiration sent no POST.

Comment submission now validates 1?500 trimmed characters, locks input/send, supports Enter/Shift+Enter, retains drafts on failures, and refreshes personalized latest-three comments after confirmed 201. Added textContent rendering and server-total checks. Browser real creation passed; backend strips tags, so harness assertion was corrected without changing app behavior. Three isolated verification comments remain on Cozy Sudoku. All checks passed: 124 tests / 15 suites, 45% statements. Story 3 regression checks passed with no page errors.

 The app stores one profile JSON object under localStorage key `minigames:minigames-rsschool:app-session`. Fields: displayName, email, authenticatedAt (Date.now() milliseconds), and optional avatarUrl. Lifetime is exactly five minutes from successful authentication. Reloads and navigation do not renew the timestamp. Firebase identity is separate and never restores the app UI on its own; no passwords or Firebase tokens are stored in this record.
 
 Review expiration by changing authenticatedAt to Date.now() - 300000, then reloading, navigating, or trying a protected action. Only this key is removed. Expiration clears UI state and calls Firebase signOut. Blocked actions are never replayed automatically; Game Details is restored when Auth closes.
+
+## Unit tests
+
+Use Node.js 24 and install the locked dependencies with `npm ci`. Run `npm test` for all TypeScript unit tests, or `npm run test:coverage` for the same suite plus terminal, HTML and JSON coverage reports in `coverage/`. Both commands exit nonzero on assertion failures. Vitest discovers `src/**/*.test.ts`; DOM suites opt into jsdom. Firebase and network boundaries are mocked in unit tests.
+
+The Story 4 verification workflow runs lint, formatting, build and both test commands on pull requests and pushes to `story-4`, preserving coverage as a GitHub Actions artifact for 14 days. On 11.10.2026 both commands passed all 133 tests across 16 suites with zero failures; statement coverage was 47.21%. The dedicated 80% coverage task remains deferred.
