feat: complete external auth V2 migration with advanced features
This commit implements comprehensive external Azure AD authentication with complete task management, file download, and admin monitoring systems. ## Core Features Implemented (80% Complete) ### 1. Token Auto-Refresh Mechanism ✅ - Backend: POST /api/v2/auth/refresh endpoint - Frontend: Auto-refresh 5 minutes before expiration - Auto-retry on 401 errors with seamless token refresh ### 2. File Download System ✅ - Three format support: JSON / Markdown / PDF - Endpoints: GET /api/v2/tasks/{id}/download/{format} - File access control with ownership validation - Frontend download buttons in TaskHistoryPage ### 3. Complete Task Management ✅ Backend Endpoints: - POST /api/v2/tasks/{id}/start - Start task - POST /api/v2/tasks/{id}/cancel - Cancel task - POST /api/v2/tasks/{id}/retry - Retry failed task - GET /api/v2/tasks - List with filters (status, filename, date range) - GET /api/v2/tasks/stats - User statistics Frontend Features: - Status-based action buttons (Start/Cancel/Retry) - Advanced search and filtering (status, filename, date range) - Pagination and sorting - Task statistics dashboard (5 stat cards) ### 4. Admin Monitoring System ✅ (Backend) Admin APIs: - GET /api/v2/admin/stats - System statistics - GET /api/v2/admin/users - User list with stats - GET /api/v2/admin/users/top - User leaderboard - GET /api/v2/admin/audit-logs - Audit log query system - GET /api/v2/admin/audit-logs/user/{id}/summary Admin Features: - Email-based admin check (ymirliu@panjit.com.tw) - Comprehensive system metrics (users, tasks, sessions, activity) - Audit logging service for security tracking ### 5. User Isolation & Security ✅ - Row-level security on all task queries - File access control with ownership validation - Strict user_id filtering on all operations - Session validation and expiry checking - Admin privilege verification ## New Files Created Backend: - backend/app/models/user_v2.py - User model for external auth - backend/app/models/task.py - Task model with user isolation - backend/app/models/session.py - Session management - backend/app/models/audit_log.py - Audit log model - backend/app/services/external_auth_service.py - External API client - backend/app/services/task_service.py - Task CRUD with isolation - backend/app/services/file_access_service.py - File access control - backend/app/services/admin_service.py - Admin operations - backend/app/services/audit_service.py - Audit logging - backend/app/routers/auth_v2.py - V2 auth endpoints - backend/app/routers/tasks.py - Task management endpoints - backend/app/routers/admin.py - Admin endpoints - backend/alembic/versions/5e75a59fb763_*.py - DB migration Frontend: - frontend/src/services/apiV2.ts - Complete V2 API client - frontend/src/types/apiV2.ts - V2 type definitions - frontend/src/pages/TaskHistoryPage.tsx - Task history UI Modified Files: - backend/app/core/deps.py - Added get_current_admin_user_v2 - backend/app/main.py - Registered admin router - frontend/src/pages/LoginPage.tsx - V2 login integration - frontend/src/components/Layout.tsx - User display and logout - frontend/src/App.tsx - Added /tasks route ## Documentation - openspec/changes/.../PROGRESS_UPDATE.md - Detailed progress report ## Pending Items (20%) 1. Database migration execution for audit_logs table 2. Frontend admin dashboard page 3. Frontend audit log viewer ## Testing Status - Manual testing: ✅ Authentication flow verified - Unit tests: ⏳ Pending - Integration tests: ⏳ Pending ## Security Enhancements - ✅ User isolation (row-level security) - ✅ File access control - ✅ Token expiry validation - ✅ Admin privilege verification - ✅ Audit logging infrastructure - ⏳ Token encryption (noted, low priority) - ⏳ Rate limiting (noted, low priority) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
