# 2026-03-28 Q-004 Coverage Remediation Pass 7

## Scope

- Continue strict `Q-004` closure work after Pass 6.
- This pass focused on:
  - fully closing the remaining `UsersPage` modal/drawer cluster
  - fully closing the remaining `WebhooksPage` modal/drawer cluster
  - materially lifting `internal/repository`
  - fixing newly exposed repository correctness defects found during stricter coverage work

## Changes

### Frontend

- Added component-level coverage in:
  - `frontend/admin/src/pages/admin/UsersPage/AssignRolesModal.test.tsx`
  - `frontend/admin/src/pages/admin/UsersPage/UserEditDrawer.test.tsx`
  - `frontend/admin/src/pages/admin/UsersPage/UserDetailDrawer.test.tsx`
  - `frontend/admin/src/pages/admin/UsersPage/CreateUserModal.behavior.test.tsx`
  - `frontend/admin/src/pages/admin/WebhooksPage/DeliveryDetailModal.test.tsx`
  - `frontend/admin/src/pages/admin/WebhooksPage/WebhookFormModal.test.tsx`
  - `frontend/admin/src/pages/admin/WebhooksPage/WebhookDeliveriesDrawer.test.tsx`
- Newly covered frontend behavior includes:
  - assign-role modal state sync, transfer changes, submit success, submit failure, and cancel reset
  - user edit drawer form hydration, birthday normalization, validation-error swallow path, service-error path, and close reset
  - user detail drawer loading, success rendering, empty fallback, fetch-failure fallback, and optional-field placeholder rendering
  - create-user modal close/reset, disabled activation-email backfill, validation-error swallow path, and service-error path
  - delivery detail modal success/failure rendering, JSON formatting branch, raw payload fallback, and close path
  - webhook form modal create/edit mode branching, validation-error swallow path, and service-error path
  - webhook deliveries drawer load, refresh, detail-open, no-webhook guard, and load-failure path

### Backend

- Added repository depth coverage in:
  - `internal/repository/repository_relationships_test.go`
- Newly covered backend logic includes:
  - `RoleRepository` lifecycle, status queries, default-role queries, search, parent queries, and ID-batch queries
  - `PermissionRepository` lifecycle, type/status queries, join-based enabled permission queries, parent queries, and ID-batch queries
  - `UserRoleRepository` create/batch-create/batch-delete/delete/delete-by-user/delete-by-role and ID projection helpers
  - `RolePermissionRepository` create/batch-create/batch-delete/delete/delete-by-role/delete-by-permission and projection helpers
- Real defects found and fixed during this pass:
  - `internal/repository/role.go`
    - explicit `status=0` role creation was being swallowed by DB defaults and persisted as enabled
  - `internal/repository/permission.go`
    - explicit `status=0` permission creation was being swallowed by DB defaults and persisted as enabled

## Verified Commands

```powershell
cd D:\project
$env:GOCACHE='D:\project\.tmp\gocache'
$env:GOPATH='D:\project\.tmp\go'
$env:GOMODCACHE='D:\project\.tmp\go\pkg\mod'
go test ./internal/repository -run 'Test(RoleRepositoryLifecycleAndQueries|PermissionRepositoryLifecycleAndQueries|UserRoleAndRolePermissionRepositoriesLifecycle)$' -count=1
go test ./internal/repository -cover -count=1
go test ./... -count=1
go vet ./...
go build ./cmd/server

cd D:\project\frontend\admin
npm.cmd run test:run -- src/pages/admin/UsersPage/AssignRolesModal.test.tsx src/pages/admin/UsersPage/UserEditDrawer.test.tsx src/pages/admin/UsersPage/UserDetailDrawer.test.tsx src/pages/admin/UsersPage/CreateUserModal.behavior.test.tsx src/pages/admin/UsersPage/CreateUserModal.test.tsx src/pages/admin/UsersPage/UsersPage.test.tsx

npm.cmd run lint
npm.cmd run build
npm.cmd run test:coverage
```

## Results

### Frontend coverage

- Overall:
  - statements `74.54%`
  - branches `63.57%`
  - functions `74.61%`
  - lines `75.35%`
- Target areas:
  - `src/pages/admin/UsersPage`: `95.06%` statements
    - `AssignRolesModal.tsx`: `100%`
    - `CreateUserModal.tsx`: `100%`
    - `UserDetailDrawer.tsx`: `100%`
    - `UserEditDrawer.tsx`: `100%`
    - `UsersPage.tsx`: `90.98%`
  - `src/pages/admin/WebhooksPage`: `94.92%` statements
    - `DeliveryDetailModal.tsx`: `100%`
    - `WebhookDeliveriesDrawer.tsx`: `96.66%`
    - `WebhookFormModal.tsx`: `96.42%`
    - `WebhooksPage.tsx`: `93.15%`

### Backend coverage

- `internal/repository`: `67.1%`

## Validation Notes

- Frontend full coverage now completes with `41` passing test files and `134` passing tests.
- The successful frontend coverage run still emits one post-summary jsdom `AggregateError` network-noise line.
  - It does not fail the command.
  - It is still a real residual hygiene issue and should continue to be tracked honestly.

## Real Conclusion

- This pass materially changed the real `Q-004` map again:
  - `UsersPage` is no longer one of the remaining dominant uncovered admin clusters
  - `WebhooksPage` is no longer one of the remaining dominant uncovered admin clusters
  - `internal/repository` is no longer at the earlier closure-blocking `37.1%` depth
- `Q-004` still cannot be honestly declared closed.
- The remaining real gaps are now more concentrated in:
  - deeper remaining frontend hotspots such as `ProfileSecurityPage`, `LoginPage`, `RegisterPage`, `AuthProvider`, and `lib/http`
  - remaining backend repository depth outside the newly covered relation/role/permission paths
  - frontend validation hygiene due the recurring post-summary jsdom `AggregateError` noise
