# Phase 18 Plan 04: Global Item Catalog Client Summary

**Global catalog browse/search page, item detail with owner count, and link-to-catalog component using TanStack Router and Query**

## Performance

- **Duration:** 4 min
- **Started:** 2026-04-05T11:14:25Z
- **Completed:** 2026-04-05T11:18:40Z
- **Tasks:** 3 (2 auto + 1 checkpoint auto-approved)
- **Files created:** 5

## Accomplishments
- Global catalog browse page with debounced search, responsive grid, and skeleton loading states
- Global item detail page showing brand, model, specs, image, description, and owner count badge
- LinkToGlobalItem component with search dropdown for linking/unlinking personal items to catalog entries
- Full set of TanStack Query hooks (useGlobalItems, useGlobalItem, useLinkItem, useUnlinkItem)

## Task Commits

Each task was committed atomically:

1. **Task 1: Global item hooks and catalog pages** - `f53f66d` (feat)
2. **Task 2: Link-to-global-item UI** - `f5233d0` (feat)
3. **Task 3: Verify global catalog UI** - auto-approved checkpoint (no commit)

## Files Created/Modified
- `src/client/hooks/useGlobalItems.ts` - Query hooks for global items API (search, detail, link, unlink)
- `src/client/components/GlobalItemCard.tsx` - Card component with brand, model, weight/price/category badges
- `src/client/components/LinkToGlobalItem.tsx` - Search-based dropdown for linking personal items to catalog
- `src/client/routes/global-items/index.tsx` - Catalog browse page with search and responsive grid
- `src/client/routes/global-items/$globalItemId.tsx` - Detail page with owner count badge

## Decisions Made
- Debounce implemented at component level (useState + useEffect with 300ms timeout) rather than in the hook, keeping hooks simple
- LinkToGlobalItem built as a standalone component that accepts itemId and linkedGlobalItemId props, making it easy to wire into any item view
- Used amber color for owner count badge to visually differentiate from blue (weight) and green (price) badges
- Skeleton loading uses static string array keys ("a" through "f") to satisfy biome's noArrayIndexKey lint rule

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None.

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Client UI complete for global item browsing, searching, and linking
- LinkToGlobalItem component ready to be wired into ItemForm or item detail views
- Ready for Plan 18-05 (discovery feed and remaining UI integration)
