# 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)

**Commits verified:**
```
FOUND: e8bef5b (feat: MemberNoteController and routes)
FOUND: 35a9f83 (feat: withCount and tests)
```

**Routes registered:**
- GET /admin/members/{member}/notes → admin.members.notes.index
- POST /admin/members/{member}/notes → admin.members.notes.store

**Tests verified:**
- All 7 tests passing
