STATISTICS:
===========

Total Lines of Code: 1,280+
- API Code: 730 lines
- Test Code: 550+ lines
- Documentation: 550+ lines

Test Cases: 55+
- List Messages: 11 tests
- Get Message: 5 tests
- Send Message: 6 tests
- Update Flags: 5 tests
- Delete Message: 3 tests
- Search: 7 tests
- Batch Operations: 3 tests
- Edge Cases/Security: 10+ tests

API Endpoints: 8
1. GET /api/accounts/:id/messages
2. GET /api/accounts/:id/messages/:msgId
3. POST /api/accounts/:id/messages
4. PUT /api/accounts/:id/messages/:msgId
5. DELETE /api/accounts/:id/messages/:msgId
6. GET /api/accounts/:id/messages/search
7. PUT /api/accounts/:id/messages/batch/flags
8. GET /api/accounts/:id/messages/:msgId/attachments/:attId/download

FEATURES IMPLEMENTED:
=====================

✓ Pagination (page, limit, metadata)
✓ Filtering (folder, flags, date range, sender, recipient)
✓ Sorting (field, order)
✓ Full-text search (relevance scoring)
✓ Message flags (isRead, isStarred, isSpam, isArchived, folder)
✓ Soft delete (default, recoverable)
✓ Hard delete (permanent, with flag)
✓ Batch operations (multiple flags updates)
✓ Multi-tenant safety (tenantId/userId filtering)
✓ Authentication (headers + query params)
✓ Error handling (consistent, informative)
✓ Auto-mark as read (on message detail view)

NEXT PHASE (Phase 8):
====================

1. DBAL Integration - Replace in-memory storage
2. Database schema - Create EmailMessage table
3. Query optimization - Add database indexes
4. Production deployment - Celery integration

USAGE:
======

Start service:
  python3 app.py

Run tests:
  pytest tests/test_messages.py -v

Read documentation:
  - PHASE_7_MESSAGES_API.md (complete spec)
  - MESSAGES_API_QUICK_REFERENCE.md (quick start)
  - PHASE_7_IMPLEMENTATION_SUMMARY.md (architecture)

Make API calls:
  curl -X GET \
    'http://localhost:5000/api/accounts/acc-1/messages' \
    -H 'X-Tenant-ID: tenant-1' \
    -H 'X-User-ID: user-1'
