+
+**TagInput component with Svelecte for multi-select autocomplete, inline tag creation, and integration into EntryCard for display and editing**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-01-31T12:06:23Z
+- **Completed:** 2026-01-31T12:09:40Z
+- **Tasks:** 2
+- **Files modified:** 6
+
+## Accomplishments
+
+- Installed Svelecte v5.3.0 for tag input with autocomplete
+- Created TagInput component with multi-select and creatable mode
+- Integrated TagInput into EntryCard expanded view
+- Added tag display in collapsed view (max 3 tags with +N indicator)
+- Updated load function to return allTags for autocomplete
+- Added updateTags action for saving tag changes
+- Passed availableTags prop through EntryList to EntryCard
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Install Svelecte and update load/actions for tags** - `cfdb804` (feat)
+2. **Task 2: Create TagInput component and integrate into EntryCard** - `0c1a66b` (feat)
+
+## Files Created/Modified
+
+- `src/lib/components/TagInput.svelte` - New component with Svelecte integration
+- `src/lib/components/EntryCard.svelte` - Added tag display and TagInput
+- `src/lib/components/EntryList.svelte` - Pass availableTags to EntryCard
+- `src/routes/+page.server.ts` - Import tagRepository, add tags to load, add updateTags action
+- `src/routes/+page.svelte` - Pass allTags to EntryList
+- `package.json` - Added svelecte dependency
+
+## Decisions Made
+
+- Use Svelecte's `onChange` prop (not `on:change`) for Svelte 5 compatibility
+- Save tags immediately on change without debounce for responsive UX
+- Display max 3 tags on collapsed cards to avoid visual clutter
+- New tags use label as temporary ID until server-side creation
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Svelecte event binding for Svelte 5**
+- **Found during:** Task 2
+- **Issue:** Plan specified `on:change` but Svelecte 5.x with Svelte 5 requires `onChange` prop
+- **Fix:** Changed from `on:change={handleChange}` to `onChange={handleChange}` prop
+- **Files modified:** src/lib/components/TagInput.svelte
+- **Commit:** 0c1a66b
+
+## Issues Encountered
+
+None beyond the Svelecte event binding fix.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Tag UI complete and functional
+- Ready for Phase 5 (Search & Filtering) - can filter by tags
+- Tag autocomplete provides foundation for tag-based filtering
