What

Migrates RubricBuilder from four whole-domain hooks to one useStoreSelector for its five data slices (studentRubrics, rubrics, gradeScales, peerReviews, settings) plus useStoreActions for its eleven actions (addRubric, updateRubric, syncRubricSnapshot, fetchRubricVersions, saveRubricVersion, restoreRubricVersion, vocabulary CRUD, saveUserTemplate).

Why

The builder only re-renders on its own draft state or its five slices now; whole-domain subscriptions previously re-rendered it on every unrelated collection update.

Notes

  • Domain-hook subscriptions drop from 4 → 0.
  • Dedicated suite routes selectors/actions through its mocked app value.

Stacked on #432 (part of the roadmap "Up Next" selector-store series).

RubricBuilder read four whole-domain hooks (useGrading, useAuthoring,
useAssessment, useSettings) for five data slices and eleven actions.
Data now comes from one useStoreSelector and actions from the stable
useStoreActions context, so the builder no longer re-renders on unrelated
collection updates.

📝 Walkthrough

Walkthrough

RubricBuilder now reads shared state with useStoreSelector and obtains authoring actions with useStoreActions. Its test mock now supports the unified store interface.

Changes

RubricBuilder store migration

Layer / File(s) Summary
Unified store access and test support
src/pages/RubricBuilder.tsx, src/pages/__tests__/RubricBuilder.test.tsx
RubricBuilder replaces separate context hooks with unified selector and action hooks. The test setup mocks selector-based state access and store actions.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 1ca92

The selector-store migration is narrowly scoped, but the template-save test uses an incomplete action mock, so it can pass after the save call throws instead of verifying a successful save. The PR is mergeable with owner follow-up to complete the mock and assert the save action.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Complete the unified store mock before testing template saves.

At Line 154, useStoreActions returns makeAppContextMock(), but makeAppContextMock does not define saveUserTemplate. RubricBuilder calls saveUserTemplate at Line 345. The call throws, handleSaveAsTemplate catches it, and the test at Lines 521-525 still passes because it only checks mockShowToast.

Add saveUserTemplate to the mock and assert the success path.

Proposed test-mock fix
 const mockSaveRubricVersion = vi.fn(async () => {});
 const mockRestoreRubricVersion = vi.fn();
+const mockSaveUserTemplate = vi.fn();
...
     deleteVocabularyItems: vi.fn(),
+    saveUserTemplate: mockSaveUserTemplate,
...
         mockRestoreRubricVersion.mockClear();
+        mockSaveUserTemplate.mockClear();
...
-        expect(mockShowToast).toHaveBeenCalled();
+        expect(mockSaveUserTemplate).toHaveBeenCalledWith(expect.objectContaining({ id: 'r1' }));
