-### Phase 14 — Core UX (NEXT)
+### Phase 14 — Core UX ✓ COMPLETE
 
 **Items:** FE-002, FE-003, FE-005, FE-007, FE-021, FE-022
-**Goal:** Replace all mocked data with real API calls, add real-time updates, state management, and multi-page navigation.
+**Status:** Complete. All 6 core items implemented.
 
-| Item | Description | Key Work |
-| ---- | ----------- | -------- |
-| FE-002 | Replace mocked API with real backend | Remove `DashboardAPI` singleton + `Math.random()` calls. Wire all 13 controllers through generated client. Implement request/response mapping for each endpoint. |
-| FE-003 | SignalR real-time client | Install `@microsoft/signalr`. Connect to `CognitiveMeshHub`. Replace polling with subscriptions (`JoinDashboardGroup`, `SubscribeToAgent`). Exponential backoff reconnection. Connection state indicator. |
-| FE-005 | Zustand state management | Create stores: `useAuthStore`, `useAgentStore`, `useDashboardStore`, `useNotificationStore`, `usePreferencesStore`. Replace scattered `useState`. Add persistence middleware for preferences. |
-| FE-007 | Loading states + skeletons | Skeleton components for dashboard panels, agent lists, metrics cards. Suspense boundaries per route. Optimistic updates for mutations. |
-| FE-021 | Multi-page routing | Create route dirs: `/dashboard`, `/settings`, `/agents`, `/compliance`, `/analytics`, `/marketplace`. Add `loading.tsx`, `error.tsx`, `layout.tsx` per route group. Parallel route loading. |
-| FE-022 | Navigation component | Sidebar with collapsible sections, breadcrumbs, mobile hamburger menu. Active route highlighting. Responsive drawer (< 768px). Keyboard navigation. |
+| Item | Description | Status |
+| ---- | ----------- | ------ |
+| FE-002 | Replace mocked API with real backend | ✓ Done — `DashboardAPI` singleton + `useDashboardData` hook deleted. Root `/` redirects to `/dashboard`. Stores fetch from real backend. |
+| FE-003 | SignalR real-time client | ✓ Done — `useSignalR` hook with `@microsoft/signalr@10.0.0`. HubConnection to `/hubs/cognitive-mesh`, exponential backoff (1s→30s), `ConnectionIndicator` in TopBar. |
+| FE-005 | Zustand state management | ✓ Done — 5 stores: `useAuthStore`, `useAgentStore`, `useDashboardStore`, `useNotificationStore`, `usePreferencesStore`. Persistence middleware for preferences. |
+| FE-007 | Loading states + skeletons | ✓ Done — `Skeleton`, `SkeletonCard`, `SkeletonTable`, `SkeletonMetric`, `SkeletonDashboard`. `loading.tsx` and `error.tsx` per route group. |
+| FE-021 | Multi-page routing | ✓ Done — `(app)` route group with 6 routes: `/dashboard`, `/agents`, `/settings`, `/analytics`, `/compliance`, `/marketplace`. Shared layout with `ProtectedRoute`. |
+| FE-022 | Navigation component | ✓ Done — `Sidebar` (collapsible), `TopBar` (breadcrumbs + notification bell), `MobileMenu` (responsive drawer), `Breadcrumbs`, `ConnectionIndicator`. Active route highlighting via `usePathname()`. |
 
-**Also in Phase 14 (deferred from Phase 13):**
+**Deferred to later phases (require backend work):**
 
 - httpOnly cookie for refresh token (requires backend `/api/auth/refresh` set-cookie endpoint)
 - Full JWT validation in middleware (requires JWKS endpoint or shared secret config)
 - Backend auth middleware in `Program.cs` (`AddAuthentication`/`AddAuthorization`)
 
+#### Gate → Phase 14b
+
+- [x] DashboardAPI mock removed, stores fetching from real backend
+- [x] SignalR hook created with reconnection logic and connection indicator
+- [x] Navigation between all 6 routes works with loading/error states
+- [x] Zustand stores hydrating from API on mount
+- [ ] Storybook stories for skeleton and navigation components (deferred to Phase 15)
+
+---
+
+### Phase 14b — UI Component Library Integration (NEXT)
+
+**Items:** FEUI-001, FEUI-002, FEUI-003, FEUI-004
+**Goal:** Merge [CognitiveMeshUI](https://github.com/phoenixvc/CognitiveMeshUI) component library into this repo. Fix broken shadcn/ui components, import design tokens, optionally wire Storybook.
+
+| Item | Description | Key Work |
+| ---- | ----------- | -------- |
+| FEUI-001 | Fix or replace broken shadcn/ui components | Existing `components/ui/` has ~50 shadcn components but missing radix deps (TS errors). Either install missing `@radix-ui/*` packages or replace with CognitiveMeshUI's working copies. |
+| FEUI-002 | Import design tokens | Bring over `tokens/` directory (colors, typography, spacing, dimensions) from CognitiveMeshUI. Integrate with Style Dictionary to generate CSS custom properties and Tailwind theme values. |
+| FEUI-003 | Wire Storybook | Import `.storybook/` config from CognitiveMeshUI. Add stories for navigation, skeleton, and shadcn/ui components. Enables visual testing (Phase 17 FETEST-004). |
+| FEUI-004 | Clean up duplicate/dead component code | Remove broken component copies, unused Bridge view components from old root `page.tsx`, and any redundant type definitions. Consolidate icon imports. |
+
+**Source:** [phoenixvc/CognitiveMeshUI](https://github.com/phoenixvc/CognitiveMeshUI) — Next.js component library with shadcn/ui, design tokens (Style Dictionary), Storybook, Framer Motion. Last updated Nov 2025.
+
+**Approach:** Direct merge (not monorepo workspaces). CognitiveMeshUI is stale and this repo is the single deployable artifact.
+
 #### Gate → Phase 15
 
-- [ ] All 13 backend controllers callable from frontend (no mocked data remains)
-- [ ] SignalR connection established and reconnecting properly
-- [ ] Navigation between all 6 routes works with loading/error states
-- [ ] Zustand stores hydrating from API on mount
-- [ ] Storybook stories exist for skeleton and navigation components
+- [ ] `npx tsc --noEmit` passes with zero errors in `components/ui/`
+- [ ] Design tokens generating CSS custom properties
+- [ ] Storybook running locally (`npm run storybook`)
+- [ ] No duplicate type definitions across stores/components
