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

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
