## Requirements Coverage Analysis

### FR-001: Master Toggle Button
- **Status**: ✅ IMPLEMENTED
- **Evidence**: Lines 319-333 in `frontend/app/(admin)/admin/ai/page.tsx`
- **Mapping**: Task T005 (US1) - Complete [X]

### FR-002: Master CSS Transitions
- **Status**: ✅ IMPLEMENTED
- **Evidence**: Line 334 in `frontend/app/(admin)/admin/ai/page.tsx` using Tailwind transitions `transition-all duration-300 ease-in-out` and dynamic height properties `max-h-0` / `max-h-[2000px]`.
- **Mapping**: Task T006 (US1) - Complete [X]

### FR-003: Collapse Toggle Button in Card Header
- **Status**: ✅ IMPLEMENTED
- **Evidence**: CardHeader section of all 5 cards has a custom `Button` with a `ChevronUp` icon.
- **Mapping**: Task T007 (US2) - Complete [X]

### FR-004: Individual Card Body Transitions
- **Status**: ✅ IMPLEMENTED
- **Evidence**: Wrapped CardContent of all 5 cards in a div with Tailwind `transition-all duration-300` and dynamic heights.
- **Mapping**: Task T008 (US2) - Complete [X]

### FR-005: localStorage Persistence
- **Status**: ✅ IMPLEMENTED
- **Evidence**: `useEffect` on component mount retrieves values from `localStorage` keys `ai_console_section_collapsed` and `ai_console_cards_collapsed`. Toggle handlers save state immediately.
- **Mapping**: Tasks T003, T004 (US1, US2) - Complete [X]

### FR-006: Card Header Remains Visible
- **Status**: ✅ IMPLEMENTED
- **Evidence**: The collapsible container wraps `CardContent` only, leaving `CardHeader` fully visible outside of it.
- **Mapping**: Tasks T007, T008 (US2) - Complete [X]

### FR-007: Tab Navigation State Preserved
- **Status**: ✅ IMPLEMENTED
- **Evidence**: Verified that React states do not reset when clicking tabs. `localStorage` is used to load initial states, and is not affected by Next.js client-side routing or Tab switches.
- **Mapping**: Tasks T011, T012 - Complete [X]

## Conclusion

**Overall Status**: ✅ PASS

The collapsible feature is fully implemented in Next.js using native React state variables, Tailwind CSS animations, and `localStorage` browser persistence, matching the mockup screen "AI Console with Fixed Collapsible Cards". Both linting and TypeScript checks passed successfully.
