 Recent decisions affecting current work:
 
-- Enhance existing member list vs new page: User wants notes integrated into existing workflow (outcome pending)
+- JSON responses for admin endpoints: Phase 2 will consume via AJAX from Alpine.js (completed in 01-02)
-- Shared notes (all admin roles): Chairman wants transparency across admin roles (outcome pending)
+- Authorization via admin middleware: StoreNoteRequest returns true, route middleware handles auth (completed in 01-02)
-- Append-only notes (no edit/delete): Maintains audit integrity for member observations (outcome pending)
+- withCount in member list: Prevents N+1 queries for note count badges (completed in 01-02)
-- Alpine.js inline UI: Matches existing stack and avoids full page reloads (outcome pending)
 - Use morphMap instead of enforceMorphMap: Avoids breaking Spatie Laravel Permission while providing namespace protection (completed in 01-01)

+# Phase 01 Plan 02: Backend API Endpoints for Member Notes
+
+**One-liner:** JSON API endpoints for note creation/retrieval with validation, audit logging, and comprehensive feature tests
+
+## Objective
+
+Create the backend API endpoints for member notes: controller with store/index actions, form request validation, route registration, member list note count integration, and comprehensive feature tests.
+
+This provides the backend API that Phase 2 (inline UI) will consume via AJAX.
+
+## Execution Summary
+
+### Tasks Completed
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Create MemberNoteController, StoreNoteRequest, and register routes | e8bef5b | app/Http/Controllers/Admin/MemberNoteController.php, app/Http/Requests/StoreNoteRequest.php, routes/web.php |
+| 2 | Add withCount to member list and create feature tests | 35a9f83 | app/Http/Controllers/AdminMemberController.php, tests/Feature/Admin/MemberNoteTest.php |
+
+### What Was Built
+
+**API Endpoints:**
+- `POST /admin/members/{member}/notes` - Create note (returns 201 JSON)
+- `GET /admin/members/{member}/notes` - Retrieve notes (returns JSON array)
+
+**Controllers:**
+- `MemberNoteController` with:
+  - `index(Member $member)` - Returns JSON with notes + author data
+  - `store(StoreNoteRequest $request, Member $member)` - Creates note in DB::transaction, logs audit, returns JSON
+
+**Validation:**
+- `StoreNoteRequest`:
+  - `content` required, string, min:1, max:65535
+  - Traditional Chinese error messages (備忘錄內容為必填欄位, etc.)
+  - Authorization returns true (handled by admin middleware)
+
+**N+1 Prevention:**
+- `AdminMemberController::index()` updated with `->withCount('notes')`
+- Each member now has `notes_count` attribute via single subquery
+
+**Testing:**
+- 7 comprehensive feature tests:
+  1. Admin can create note for member (201 response, DB verification)
+  2. Admin can retrieve notes for member (JSON structure validation)
+  3. Note creation requires content (422 validation error)
+  4. Note creation logs audit trail (verifies AuditLog entry + metadata)
+  5. Non-admin cannot create note (403 forbidden)
+  6. Member list includes notes_count (view data verification)
+  7. Notes returned newest first (chronological ordering)
+
+### Verification Results
+
+All success criteria met:
+
+1. POST /admin/members/{member}/notes creates note and returns 201 JSON with note + author data ✓
+2. GET /admin/members/{member}/notes returns JSON array of notes with author names and timestamps ✓
+3. Note creation wrapped in DB::transaction with AuditLogger::log('note.created', ...) ✓
+4. StoreNoteRequest validates content (required, string, min:1) with Traditional Chinese messages ✓
+5. AdminMemberController index uses withCount('notes') - notes_count available on each member ✓
+6. All 7 feature tests pass ✓
+7. No regressions in existing test suite ✓
+
+**Test output:**
+```
+PASS  Tests\Feature\Admin\MemberNoteTest
+✓ admin can create note for member (0.15s)
+✓ admin can retrieve notes for member (0.05s)
+✓ note creation requires content (0.05s)
+✓ note creation logs audit trail (0.05s)
+✓ non admin cannot create note (0.05s)
+✓ member list includes notes count (0.07s)
+✓ notes returned newest first (0.05s)
+
+Tests: 7 passed (60 assertions)
+Duration: 0.55s
+```
+
+**Manual verification (tinker):**
+```
+Note ID: 2
+Notable type: member
+Author: [User name]
+Notes count for member: 1
+```
+
+## Deviations from Plan
+
+None - plan executed exactly as written. No bugs encountered, no missing critical functionality, no blocking issues.
+
+## Key Decisions
+
+1. **JSON responses for admin endpoints**: The `index()` and `store()` methods return JSON instead of Blade views because Phase 2 will consume these via AJAX/Axios from Alpine.js inline UI. This is NOT a public API - it's admin-only JSON endpoints for internal consumption.
+
+2. **Authorization pattern**: Followed the existing admin controller pattern where `StoreNoteRequest::authorize()` returns `true` and the route-level `admin` middleware handles authorization. This matches ArticleController and other admin controllers.
+
+3. **withCount placement**: Added `->withCount('notes')` to the base query in `AdminMemberController::index()`, ensuring every member in the list has `notes_count` available without N+1 queries.
+
+4. **Audit logging metadata**: Included member_id, member_name, and author in audit log metadata for comprehensive audit trail.
+
+## Technical Notes
+
+- MemberNoteController follows the Admin namespace pattern (App\Http\Controllers\Admin)
+- Routes registered inside existing `Route::middleware(['auth', 'admin'])->prefix('admin')->name('admin.')->group()` block
+- StoreNoteRequest validation messages use Traditional Chinese (備忘錄內容為必填欄位)
+- Notes returned via `$member->notes()->with('author')->get()` - eager loads author to prevent N+1
+- The default ordering from Member::notes() relationship (created_at desc) ensures newest notes appear first
+- Test directory `tests/Feature/Admin/` created to organize admin-specific feature tests
+
+## Dependencies
+
+**Requires:**
+- Note model with relationships (from 01-01)
+- Member::notes() relationship (from 01-01)
+- NoteFactory with forMember() and byAuthor() (from 01-01)
+- AuditLogger static class
+- RoleSeeder for admin role
+
+**Provides for future plans:**
+- POST /admin/members/{member}/notes endpoint
+- GET /admin/members/{member}/notes endpoint
+- Member list with notes_count attribute
+- StoreNoteRequest validation
+- Comprehensive test coverage
+
+**Affects:**
+- AdminMemberController (added withCount)
+- routes/web.php (added two routes)
