2026-03-28 Q-004 Coverage Remediation Pass 10

Scope

• Continue strict Q-004 closure work after Pass 9.
• Fully close the remaining RegisterPage frontend page cluster before moving to the next task.
• Re-verify closure through targeted tests plus full frontend validation.

Changes

Frontend

• Expanded register-page behavior coverage in:
  • frontend/admin/src/pages/auth/RegisterPage/RegisterPage.test.tsx
• Newly covered behavior includes:
  • fallback to default capabilities when capability loading fails
  • footer rendering when password-reset capability is enabled
  • sms-code send success, validation swallow path, and backend-failure path
  • sms-backed registration payload submission
  • submit blocking when sms-backed registration is missing a valid phone-code path
  • registration failure handling
  • inactive-account success summary with and without activation email
  • first-admin bootstrap warning rendering

Backend

• No backend code changes were required in this pass.

Verified Commands

cd D:\project\frontend\admin
npm.cmd run test:run -- src/pages/auth/RegisterPage/RegisterPage.test.tsx
npm.cmd run lint
npm.cmd run build
npm.cmd run test:coverage

Results

Frontend coverage

• Overall:
  • statements 78.91%
  • branches 66.06%
  • functions 77.07%
  • lines 79.73%
• Target areas:
  • src/pages/auth/RegisterPage/RegisterPage.tsx: statements 93.42%, branches 85.24%, functions 87.5%, lines 95.89%
  • src/pages/admin/ProfileSecurityPage/ProfileSecurityPage.tsx: statements 70.17%, branches 48.97%
  • src/lib/http/client.ts: statements 52.17%, branches 43.26%
  • src/lib/http/csrf.ts: statements 25.71%, branches 19.23%

Validation Notes

• Frontend full coverage now completes with 41 passing test files and 163 passing tests.
• The required sequential frontend validation path passed:
  • 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

• RegisterPage is no longer an open Q-004 gap.
• Q-004 still cannot be honestly declared closed.
• The remaining highest-value frontend gaps are now more concentrated in:
  • deeper remaining ProfileSecurityPage branches
  • lib/http
