# Phase 02 Plan 03: Inline Editing Summary

**Expandable EntryCard with 400ms debounced auto-save and CompletedToggle for showing/hiding completed tasks**

## Performance

- **Duration:** 3 min
- **Started:** 2026-01-29T10:10:33Z
- **Completed:** 2026-01-29T10:13:19Z
- **Tasks:** 2
- **Files modified:** 4

## Accomplishments
- EntryCard expands on click to show inline editing fields
- Changes auto-save with 400ms debounce showing "Saving..." indicator
- Type can be changed after entry creation (task/thought)
- CompletedToggle shows/hides completed tasks with persistence
- Delete button with confirmation dialog in expanded view

## Task Commits

Each task was committed atomically:

1. **Task 1: Add expand/collapse and inline editing to EntryCard** - `7d66a8f` (feat)
2. **Task 2: Create CompletedToggle component and wire up showCompleted** - `fc7c1f6` (feat)

## Files Created/Modified
- `src/lib/components/EntryCard.svelte` - Expanded from 67 to 200 lines with expand/collapse state, inline editing fields, debounced auto-save
- `src/lib/components/CompletedToggle.svelte` - New 42-line component for toggling completed tasks visibility
- `src/routes/+page.svelte` - Added CompletedToggle to header, URL preference sync
- `src/routes/+page.server.ts` - Load function accepts showCompleted URL param

## Decisions Made
- Used fetch to ?/update for auto-save instead of form submit (seamless UX, no page refresh)
- Synced showCompleted preference with URL params for server-side filtering
- Fixed button-in-button nesting issue by restructuring to div with role="button"
- Added keyboard handler (Enter/Space) for accessibility on clickable div

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 1 - Bug] Fixed button-in-button HTML nesting**
- **Found during:** Task 1 (EntryCard implementation)
- **Issue:** Original plan had button wrapping the entire header including the checkbox form button, causing HTML validation error and hydration warnings
- **Fix:** Restructured to use div with role="button" for clickable content area, keeping form button separate
- **Files modified:** src/lib/components/EntryCard.svelte
- **Verification:** svelte-check passes with no errors
- **Committed in:** 7d66a8f (Task 1 commit)

---

**Total deviations:** 1 auto-fixed (1 bug)
**Impact on plan:** Essential fix for HTML validity and SSR hydration. No scope creep.

## Issues Encountered
- Svelte 5 `page` from `$app/state` is not a store - fixed by accessing directly without $ prefix
- Svelte warnings about state capturing initial values are intentional (edit state should capture, not track)

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- Core CRUD operations fully functional
- Ready for Plan 04 (drag-drop reordering if planned)
- Requirements satisfied: CORE-02 (Edit), CORE-03 (Delete with confirmation), CORE-06 (Add notes)
