+  - phase: 02-core-crud/03
+    provides: EntryCard with inline editing, form actions
+provides:
+  - Swipe-to-delete gesture for mobile users
+  - Touch-friendly delete confirmation overlay
+  - Seamless list updates via invalidateAll
+affects: [mobile-ux, phase-3-images]
+
+# Tech tracking
+tech-stack:
+  added:
+    - svelte-gestures (installed but replaced with native handlers)
+  patterns:
+    - Native touch handlers (touchstart/touchmove/touchend) for swipe gestures
+    - invalidateAll() for seamless data refresh after mutations
+
+key-files:
+  created: []
+  modified:
+    - src/lib/components/EntryCard.svelte
+    - package.json
+
+key-decisions:
+  - "Use native touch handlers instead of svelte-gestures for better visual feedback"
+  - "invalidateAll() after save/delete instead of page reload for seamless UX"
+  - "$effect to sync edit state when entry prop changes"
+
+patterns-established:
+  - "Swipe-to-delete: touchstart captures start position, touchmove updates offset, touchend snaps or confirms"
+  - "Mutation refresh: invalidateAll() after fetch-based form actions for list sync"

+# Phase 02 Plan 04: Mobile UX Summary
+
+**Swipe-to-delete gesture with native touch handlers and seamless list updates via invalidateAll**
+
+## Performance
+
+- **Duration:** 5 min (excludes checkpoint verification time)
+- **Started:** 2026-01-29T11:14:09Z
+- **Completed:** 2026-01-29T14:27:05Z (includes 3h checkpoint pause)
+- **Tasks:** 2 (1 auto + 1 human-verify checkpoint)
+- **Files modified:** 3
+
+## Accomplishments
+- Swipe-to-delete gesture working on mobile devices
+- Visual feedback during swipe (red delete icon reveals as user swipes left)
+- Confirmation overlay with Cancel/Delete buttons meeting touch target requirements
+- Seamless list updates after save/delete operations via invalidateAll()
+- All touch targets meet WCAG 44x44px minimum with min-w/min-h classes
+- Phase 2 Core CRUD fully complete and verified
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Install svelte-gestures and implement swipe-to-delete** - `104c437` (feat)
+2. **Post-checkpoint fix: Improve swipe with direct touch handlers** - `1533759` (fix)
+
+## Files Created/Modified
+- `src/lib/components/EntryCard.svelte` - Added swipe gesture handling, delete confirmation overlay, invalidateAll integration (now 337 lines)
+- `package.json` - Added svelte-gestures dependency
+- `package-lock.json` - Lock file updated
+
+## Decisions Made
+- Used native touch event handlers (touchstart/touchmove/touchend) instead of svelte-gestures library for better visual swipe feedback during gesture
+- Replaced window.location.reload() with invalidateAll() for seamless list updates after save/delete
+- Added $effect to sync edit state when entry prop changes from parent (after invalidateAll refreshes data)
+- Touch target sizes explicitly set with min-w-[44px] and min-h-[44px] on confirmation buttons
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] svelte-gestures lacked visual swipe feedback**
+- **Found during:** Checkpoint verification
+- **Issue:** Original svelte-gestures implementation detected swipe direction but didn't provide real-time offset tracking for visual feedback during swipe
+- **Fix:** Replaced with native touch handlers that track swipeOffset state, updating transform in real-time
+- **Files modified:** src/lib/components/EntryCard.svelte
+- **Verification:** User verified swipe shows red background revealing smoothly
+- **Committed in:** 1533759 (post-checkpoint fix)
+
+**2. [Rule 1 - Bug] List didn't update after save**
+- **Found during:** Checkpoint verification
+- **Issue:** After saving edits, the entry list didn't reflect changes until page refresh
+- **Fix:** Added invalidateAll() after fetch to ?/update and ?/delete actions
+- **Files modified:** src/lib/components/EntryCard.svelte
+- **Verification:** Changes appear immediately in list without refresh
+- **Committed in:** 1533759 (post-checkpoint fix)
+
+---
+
+**Total deviations:** 2 auto-fixed (2 bugs)
+**Impact on plan:** Both fixes essential for correct UX. svelte-gestures dependency remains installed but unused.
+
+## Issues Encountered
+- svelte-gestures useSwipe hook didn't provide swipe position during gesture, only direction on completion - resolved by implementing native touch handlers
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- All Phase 2 Core CRUD requirements complete
+- Entry creation, editing, deletion, completion toggle all working
+- Mobile UX verified with swipe-to-delete and adequate touch targets
+- Ready for Phase 3 (Image Support) which is the core differentiator
+
+**Phase 2 Requirements Status:**
+- CORE-01 Create: Quick capture working
+- CORE-02 Edit: Inline editing with auto-save
+- CORE-03 Delete: Swipe-to-delete (mobile) + button (desktop) with confirmation
+- CORE-04 Complete: Checkbox toggle with completed filter
+- CORE-05 Type distinction: Task/thought type selector and indicators
+- CORE-06 Notes: Content field for adding notes
+- UX-01 Mobile-friendly: Verified
+- UX-02 Readable fonts: Base 16px, minimum 14px
