+# 2026-03-28 Q-004 Coverage Remediation Pass 13
+
+## Scope
+
+- Continue strict `Q-004` closure work after Pass 12.
+- Fully close the remaining deep-branch hotspot in `frontend/admin/src/pages/admin/ProfileSecurityPage/ProfileSecurityPage.tsx` before selecting the next gap.
+- Re-verify closure through targeted page tests plus full frontend validation.
+
+## Changes
+
+### Frontend
+
+- Extended page coverage in:
+  - `frontend/admin/src/pages/admin/ProfileSecurityPage/ProfileSecurityPage.behavior.test.tsx`
+- Newly covered behavior includes:
+  - initial security-data load failure handling
+  - OAuth callback success and error handling
+  - password-update submission
+  - bound social-account unbind flow and post-action refresh
+  - no-user guard behavior for protected actions
+  - existing TOTP, avatar, and device behavior remained green under the rewritten page-level tests
+
+### Backend
+
+- No backend code changes were required in this pass.
+
+## Verified Commands
+
+```powershell
+cd D:\project\frontend\admin
+npm.cmd run test:run -- src/pages/admin/ProfileSecurityPage
+npm.cmd run lint
+npm.cmd run build
+npm.cmd run test:coverage
+```
+
+## Results
+
+### Frontend coverage
+
+- Overall:
+  - statements `85.89%`
+  - branches `74.91%`
+  - functions `81.87%`
+  - lines `86.71%`
+- Target areas:
+  - `src/pages/admin/ProfileSecurityPage/ProfileSecurityPage.tsx`: statements `90.35%`, branches `75.51%`, functions `92.45%`, lines `90.13%`
+  - `src/lib/http/client.ts`: statements `100%`, branches `92.30%`, functions `100%`, lines `100%`
+  - `src/lib/http/csrf.ts`: statements `100%`, branches `88.46%`, functions `100%`, lines `100%`
+
+## Validation Notes
+
+- Frontend full coverage now completes with `42` passing test files and `199` passing tests.
+- The required sequential frontend validation path passed:
+  - `test:run -- src/pages/admin/ProfileSecurityPage`
+  - `lint`
+  - `build`
+  - `test:coverage`
+- The successful frontend coverage run still emits one post-summary jsdom `AggregateError` network-noise line.
+  - It does not fail the command.
+  - It remains a real validation-hygiene issue and should continue to be tracked honestly.
+
+## Real Conclusion
+
+- `src/pages/admin/ProfileSecurityPage/ProfileSecurityPage.tsx` is no longer an open `Q-004` gap.
+- `Q-004` still cannot be honestly declared closed.
+- With `client.ts` and `ProfileSecurityPage` closed, the next highest-value frontend gaps shift to:
+  - auth recovery pages that still have `0%` coverage, especially `src/pages/auth/ForgotPasswordPage/ForgotPasswordPage.tsx`
+  - `src/pages/auth/ResetPasswordPage/ResetPasswordPage.tsx`
+  - the post-summary jsdom `AggregateError` coverage-noise hygiene issue
