  - phase: 03-03
    provides: camera capture functionality (later replaced with file input)
provides:
  - ImageGallery component with horizontal scrolling thumbnails
  - ImageLightbox component for fullscreen image viewing
  - Image delete functionality with edit mode toggle
  - Camera button using native file input with capture attribute
  - Entry card image indicator in collapsed view
affects: [future image features, mobile camera workflows]

# Tech tracking

  added: []
  patterns: [horizontal scroll gallery, modal lightbox, file input capture="environment"]

key-files:
  created:
    - src/lib/components/ImageGallery.svelte

key-decisions:
  - "Horizontal scroll gallery with 80x80 thumbnails"
  - "Simple custom lightbox instead of library dependency"
  - "Edit mode toggle reveals delete buttons on images"
  - "File input with capture=\"environment\" instead of getUserMedia"
  - "Native OS camera picker works over HTTP"

patterns-established:
  - "Gallery pattern: horizontal scroll with overflow-x-auto"
  - "Lightbox: fixed overlay with click-outside and escape key close"
  - "Edit mode: toggle button to reveal destructive actions"
  - "Mobile camera: use capture attribute for native camera access"

# Phase 03 Plan 04: Gallery & Integration Summary

**Image gallery integration with horizontal thumbnails, fullscreen lightbox, delete functionality, and native camera button using file input capture attribute**

## Performance

- **Duration:** 8 min (including verification fix)
- **Tasks:** 4 (3 auto + 1 checkpoint)
- **Files created:** 2
- **Files modified:** 3

## Accomplishments
- ImageGallery component renders horizontal scrolling 80x80 thumbnails
- ImageLightbox shows full-size image with keyboard navigation (arrows, escape)
- EntryCard shows image count indicator when collapsed
- Expanded entry shows full image gallery with edit mode for deletion
- deleteImage form action removes files from disk and database
- Camera button replaced with native file input using capture="environment"
- Complete image flow verified: upload, view, delete, camera capture

## Task Commits

Each task was committed atomically:

1. **Task 1: ImageGallery and ImageLightbox components** - `eaf976f` (feat)
2. **Task 2: Integrate images into EntryCard** - `0acff1b` (feat)
3. **Task 3: Delete image form action** - `b239862` (feat)
4. **Task 4: Human verification checkpoint** - approved
5. **Fix: Camera button using file input** - `a2f9183` (fix)

## Files Created/Modified

### Created
- `src/lib/components/ImageGallery.svelte` - Horizontal scrolling gallery with edit mode (89 lines)
- `src/lib/components/ImageLightbox.svelte` - Fullscreen lightbox with keyboard nav (132 lines)

### Modified
- `src/lib/components/EntryCard.svelte` - Integrated gallery, upload, camera, delete functionality
- `src/lib/components/EntryList.svelte` - Pass images to EntryCard
- `src/routes/+page.server.ts` - Added deleteImage form action

## Decisions Made
- **Custom lightbox over library:** Simple modal with click-outside/escape close is sufficient; no need for svelte-lightbox dependency
- **Edit mode toggle:** Hide delete buttons by default to prevent accidental deletion
- **File input with capture="environment":** Works over HTTP unlike getUserMedia which requires HTTPS (except localhost)

## Deviations from Plan

### Fixed During Verification

**1. [Rule 1 - Bug] Camera button fix: replaced CameraCapture modal with file input**
- **Found during:** Human verification checkpoint
- **Issue:** CameraCapture component using getUserMedia failed on HTTP connections (not localhost); camera requires HTTPS except for localhost
- **Fix:** Replaced CameraCapture modal with a hidden file input using `capture="environment"` attribute, which triggers native OS camera picker
- **Files modified:** src/lib/components/EntryCard.svelte
- **Verification:** Camera button works on mobile over HTTP, opens native camera app
- **Committed in:** `a2f9183`

---

**Total deviations:** 1 fix during verification
**Impact on plan:** Simpler, more compatible camera implementation with better browser support

## Issues Encountered

- **getUserMedia HTTPS requirement:** The CameraCapture component from 03-03 uses getUserMedia which only works on HTTPS (with localhost exception). During verification over the local network via HTTP, camera access was blocked. Fixed by using the native file input capture attribute instead.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- Phase 3 (Images) is complete
- Full image lifecycle: upload, view thumbnails, view fullscreen, delete
- Camera capture works on mobile devices
- Ready for Phase 4 (Search) or Phase 5 (Sync)
