2026-03-28 Q-004 Coverage Remediation Pass 25

Scope

• Continue strict Q-004 closure work after Pass 24.
• Fully close the theme-provider hotspot in:
  • frontend/admin/src/app/providers/ThemeProvider.tsx
• Re-verify closure through targeted provider tests and full frontend validation.

Changes

Frontend

• Added dedicated provider coverage in:
  • frontend/admin/src/app/providers/ThemeProvider.test.tsx
• Newly verified behavior includes:
  • child rendering through ConfigProvider
  • locale propagation to ConfigProvider
  • theme token propagation to ConfigProvider
  • component-level theme override propagation for Table, Card, Button, Input, and Select

Backend

• No backend code changes were required in this pass.

Verified Commands

cd D:\project\frontend\admin
npm.cmd run test:run -- src/app/providers/ThemeProvider.test.tsx
npm.cmd run lint
npm.cmd run build
npm.cmd run test:coverage

Results

Frontend coverage

• Overall:
  • statements 93.93%
  • branches 82.29%
  • functions 91.37%
  • lines 94.10%
• Target area:
  • src/app/providers/ThemeProvider.tsx: statements 100%, branches 100%, functions 100%, lines 100%

Validation outcomes

• Targeted provider validation passed:
  • 1 passing test file
  • 1 passing test
• Full frontend coverage run now completes with:
  • 54 passing test files
  • 248 passing tests
• The required sequential frontend validation path passed:
  • test:run -- src/app/providers/ThemeProvider.test.tsx
  • lint
  • build
  • test:coverage

Validation Notes

• The successful frontend coverage run still emits post-summary jsdom AggregateError network-noise lines.
  • The command exits with code 0.
  • This remains a real validation-hygiene issue and cannot be hidden or described as a fully clean run.

Real Conclusion

• src/app/providers/ThemeProvider.tsx is no longer an open Q-004 gap.
• All previously identified frontend code hotspots for this closure track are now covered and re-verified.
• Q-004 still cannot be honestly declared closed because one real validation-hygiene issue remains:
  • the post-summary jsdom AggregateError coverage-noise issue
