Fixed by implementing Option A: Show flyout with empty state. Changes in `src/src/App.tsx`: 1. Removed `&& libraryThreads.length > 0` condition - flyout now always appears on hover 2. Added empty state UI when no threads exist: - 'No searches yet. Start a search to build your library!' - 'New Search' button that navigates to home 3. Wrapped 'Recent' section in `libraryThreads.length > 0` check to hide when empty

## Triage Report ### Summary The library hover flyout **IS implemented** in `src/src/App.tsx:166-290`. The code is correct but the flyout only appears when both conditions are met: 1. User is authenticated (so `getThreads()` succeeds) 2. At least 1 thread exists in the database ### Root Cause Analysis The flyout doesn't appear because of a **guard condition**: ```tsx {hoveredNavItem === 'library' && libraryThreads.length > 0 && ( // flyout JSX... )} ``` When `getThreads()` fails (401 auth error) or returns empty array, `libraryThreads` stays empty and the flyout never renders. ### Investigation Findings 1. **Implementation exists**: Added in commit 6f9303d - "Add frontend routing and container refactoring" 2. **Hover handlers are wired**: - App.tsx defines handleLibraryMouseEnter/handleLibraryMouseLeave - Passed to Library nav item in primaryNavItems - NavItem.tsx properly forwards these to DOM events 3. **API requires auth**: curl returns {"detail":"Not authenticated"} 4. **Silent failure**: The useEffect catches errors but only logs them ### Possible Fixes **Option A**: Show flyout with "empty state" when no threads exist - Modify condition to just `hoveredNavItem === 'library'` - Add empty state UI: "No threads yet. Start a search!" **Option B**: Debug why auth isn't passing to the API call - Check if auth token is being included in getThreads() fetch - Verify 401 interceptor isn't redirecting before threads load **Option C**: Ensure threads exist for testing - The flyout works correctly when logged in AND threads exist - Issue may be a data/state problem rather than code bug ### Recommended Next Steps 1. Log in to the live site and check browser console for errors 2. Verify there are threads in the database 3. Check Network tab to see if /api/threads is called and what response is returned
