+# Phase 03 Plan 01: Expandable Note History Panel with Search
+
+**One-liner:** Clickable note count badge expands inline history panel with search filtering, showing all notes newest-first with author attribution and formatted timestamps.
+
+## What Was Built
+
+### Core Functionality
+
+1. **Expandable History Panel**
+   - Note count badge is now a clickable button that toggles expansion panel
+   - Panel appears as a new `<tr>` row below the member row using `x-collapse` animation
+   - Loading spinner shown while fetching notes (lazy load on first open)
+   - Panel collapses cleanly when badge clicked again, search query auto-resets
+
+2. **Note Display**
+   - Notes displayed newest first (explicit `latest('created_at')` in controller)
+   - Author name and formatted datetime shown: `{author} · {YYYY年MM月DD日 HH:mm}`
+   - Content preserves line breaks with `whitespace-pre-line`
+   - Left border accent (blue) for visual separation
+   - Scrollable container (max-h-64) when >5-6 notes
+
+3. **Search Filtering**
+   - Search input appears only when notes exist
+   - Filters notes by content OR author name (case-insensitive)
+   - Client-side filtering via Alpine.js computed property `filteredNotes`
+   - Shows "找不到符合的備忘錄" when search has no matches
+
+4. **Empty States**
+   - "尚無備註" when member has no notes
+   - "找不到符合的備忘錄" when search yields no results
+
+5. **Cache Synchronization**
+   - After adding note via inline form, new note appears in history panel immediately
+   - No re-fetch required (uses `this.notes.unshift(response.data.note)`)
+
+### Technical Implementation
+
+**Alpine.js Collapse Plugin**
+```javascript
+import collapse from '@alpinejs/collapse';
+Alpine.plugin(collapse);
+```
+
+**Per-Row State Extended**
+Added to existing x-data scope:
+- `historyOpen: false` — panel visibility
+- `notes: []` — cached note data
+- `notesLoaded: false` — has data been fetched
+- `isLoadingNotes: false` — loading state
+- `searchQuery: ''` — search input value
+- `toggleHistory()` — open/close + lazy load
+- `loadNotes()` — fetch from API
+- `filteredNotes` — computed property for search
+- `formatDateTime()` — format to Traditional Chinese
+
+**Controller Optimization**
+```php
+// Before (implicit ordering, full user model)
+$notes = $member->notes()->with('author')->get();
+
+// After (explicit ordering, minimal fields)
+$notes = $member->notes()->with('author:id,name')->latest('created_at')->get();
+```
+
+**Template Structure**
+```html
+<template x-data="{ ...all state... }">
+    <tr><!-- Main member row --></tr>
+    <tr x-show="historyOpen" x-collapse><!-- Expansion panel --></tr>
+</template>
+```
+
+Using `<template>` wrapper allows sibling `<tr>` elements to share Alpine.js state while maintaining valid table HTML.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed controller ordering from implicit to explicit**
+- **Found during:** Task 1 implementation
+- **Issue:** Controller used `$member->notes()->with('author')->get()` with no explicit ordering. This worked only because SQLite insertion order happened to match newest-first. Would break if seeder or database changed.
+- **Fix:** Added explicit `->latest('created_at')` to guarantee newest-first ordering.
+- **Files modified:** `app/Http/Controllers/Admin/MemberNoteController.php`
+- **Commit:** c0ebbdb
+
+**2. [Rule 2 - Optimization] Narrowed eager load to only needed fields**
+- **Found during:** Task 1 implementation
+- **Issue:** Controller loaded full `author` user model, but view only needs `id` and `name`.
+- **Fix:** Changed `->with('author')` to `->with('author:id,name')` to reduce payload size.
+- **Files modified:** `app/Http/Controllers/Admin/MemberNoteController.php`
+- **Commit:** c0ebbdb
+
+No architectural changes needed. No user decisions required.
+
+## Testing
+
+### New Tests Added (4)
+
+1. **`test_notes_index_returns_author_name_and_created_at`**
+   - Verifies API returns properly structured data for display
+   - Tests multiple authors are represented correctly
+
+2. **`test_notes_index_returns_empty_array_for_member_with_no_notes`**
+   - Verifies empty state data contract
+
+3. **`test_member_list_renders_history_panel_directives`**
+   - Verifies Blade view contains all necessary Alpine.js directives
+   - Checks for: `toggleHistory`, `historyOpen`, `x-collapse`, `searchQuery`, `filteredNotes`, etc.
+
+4. **`test_store_note_returns_note_with_author_for_cache_sync`**
+   - Verifies store endpoint returns complete note data needed for frontend cache sync
+   - Ensures `author.name` is included in response
+
+### Test Results
+
+```
+✓ All 11 tests pass (7 existing + 4 new)
+✓ 86 assertions
+✓ Duration: 0.72s
+```
+
+## Verification Checklist
+
+- [x] `npm run build` completes without errors
+- [x] `php artisan test --filter=MemberNoteTest` — all 11 tests pass

+- [x] Expansion panel uses `x-collapse` directive
+- [x] Search input present with `x-model="searchQuery"`
+- [x] Empty state text "尚無備註" present
+- [x] No-results state "找不到符合的備忘錄" present
+- [x] Controller index method uses `->latest('created_at')`
+- [x] Controller eager loads only `author:id,name`
+- [x] `submitNote()` has `this.notes.unshift(response.data.note)` cache sync
+- [x] `formatDateTime` method exists in x-data scope
+
+## Success Criteria Met
+
+- [x] Admin can click note count badge to expand inline panel showing all notes for that member
+- [x] Notes display newest first with author name and formatted datetime (YYYY年MM月DD日 HH:mm)
+- [x] Panel shows "尚無備註" when member has no notes
+- [x] Admin can filter notes by text content or author name via search input
+- [x] Closing panel resets search query; other member rows unaffected
+- [x] Adding a note via inline form immediately appears in the history panel without re-fetch

+
+## Integration Points
+
+**Consumes:**
+- `GET /admin/members/{member}/notes` — notes index endpoint (Phase 01)
+- `POST /admin/members/{member}/notes` — store endpoint (Phase 01)
+- `$member->notes_count` — eager loaded count from Phase 02
+
+**Provides:**
+- Expandable history panel UI component (completes member note feature)
+- Client-side search pattern (can be reused for other list views)
+
+**Affects:**
+- Member list page now has two interactive note features: inline add form (Phase 02) + history panel (Phase 03)
+- Both features share Alpine.js state via template wrapper pattern
+
+## Known Limitations
+
+1. **Search is client-side only** — All notes loaded upfront, then filtered in browser. Fine for typical use (most members have <20 notes), but could become slow if a member has hundreds of notes.
+
+2. **No pagination in history panel** — All notes rendered, scrollable container limits visible area. If note volume grows significantly, consider adding pagination or virtual scrolling.
+
+3. **No real-time updates** — If another admin adds a note to the same member, current user won't see it until they close and re-open the panel (triggers fresh fetch). Could add WebSocket/polling if multi-user concurrency becomes important.
+
+4. **Datetime formatting is client-side JavaScript** — Uses browser's Date object. Assumes server returns ISO 8601 timestamps. No timezone conversion (assumes all users in same timezone).
+
+## Next Steps
+
+**Immediate:**
+- No further work needed for note history feature — complete as designed
+
+**Future Enhancements (if needed):**
+- Add edit/delete note actions in history panel (currently view-only)
+- Add note categories/tags for better organization
+- Add server-side search endpoint if note volume grows significantly
+- Add real-time updates via WebSocket for multi-user scenarios
