+# 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
+
+```powershell
+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
