What

Migrates StudentPortalPage from five whole-domain hooks to one useStoreSelector for its 16 data slices plus useStoreActions for its 12 actions (saveRubricSelfAssessment, fetchMyTestAssignments, fetchAssignedTestContent, fetchMyEssayAssignments, fetchMyMessages, sendMessageAsStudent, markMessagesReadByStudent, fetchMyNewsFlashes, markNewsFlashRead, markNewsFlashReadAsStudent, fetchMyFlashcardAssignments, updateSettings).

Why

The portal re-rendered on any change to five domains; it now re-renders only when one of the 16 slices it renders changes.

Notes

  • Domain-hook subscriptions drop from 5 → 0.
  • pages.smoke.test.tsx selector defaults gained newsFlashes/newsFlashReads so the portal genuinely renders there instead of crashing into the router error boundary.

Stacked on #437 (part of the roadmap "Up Next" selector-store series).

The portal read sixteen data slices and triggered twelve actions across
five whole-domain hooks. Data now comes from one useStoreSelector and
actions from the stable useStoreActions context. The smoke suite's
selector mock also gained newsFlashes/newsFlashReads defaults so the
portal genuinely renders there.

Review Change Stack

📝 Walkthrough

Walkthrough

StudentPortalPage now uses centralized store hooks for portal state and actions. Tests mock these hooks and include default news flash collections in the smoke-test store state.

Changes

Student portal store migration

Layer / File(s) Summary
Centralized portal store integration
src/pages/StudentPortalPage.tsx, src/pages/__tests__/StudentPortalPage.test.tsx, src/pages/__tests__/pages.smoke.test.tsx
StudentPortalPage replaces domain-specific context hooks with useStoreSelector and useStoreActions. Tests mock the centralized hooks and define default newsFlashes and newsFlashReads collections.

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

Merge Risk: 🟡 Moderate · up to 93c46

The page now consumes additional store actions, but the affected test fixtures do not provide all of them, causing smoke and theme-toggle paths to fail with undefined-function errors. This is a bounded merge-readiness issue that should be fixed before merge.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Align both test fixtures with the page's store action bundle.

StudentPortalPage now consumes additional actions that the fixtures do not provide. Add the fetch, messaging, flashcard, news-flash, and updateSettings mocks used during mount and interaction; otherwise the smoke and theme-toggle paths can call undefined and throw a TypeError.

Update src/pages/__tests__/StudentPortalPage.test.tsx#L215-L218 with an updateSettings: vi.fn() mock and add the remaining actions required by the smoke fixture.
