- Section 6.3: Replace single-project tracking with multi-project aggregation model
(sub-account → N projects, each with independent monitoring toggle,
spending = sum of all enabled projects)
- Section 7.4: Add multi-project to flow diagram and key design points
- Section 11: Update AirGate implementation flow and add project CRUD API endpoints
- Section 1.1: Update requirements table to reflect multi-project
- Section 12: Update limitations to describe multi-project tracking

Quota allocation system:
- Replace monthly budget with one-time quota allocation (prepaid model)
- Support both adding (+) and deducting (-) quota with underflow protection
- Stepped alerts at configurable percentages (e.g., 50%/80%/90%)
- Auto-disable when quota exhausted (100%), alert state resets on new allocation
- Quota allocation history with operator audit trail
IAM management:
- Create new IAM sub-accounts directly from AirGate (auto-generates API keys)
- SecretKey shown once in dialog with copy-to-clipboard
- Attach/detach IAM policies via UI (ArkFullAccess, TOSFullAccess, etc.)
- Sync existing users from Volcengine
- Project list pulled from Volcengine API for dropdown selection
Security & auth:
- API Key authentication for external systems (AirDrama integration)
- SECRET_KEY enforced in production (raises error if missing with DEBUG=False)
- APIKeyUser with proper pk/is_staff attributes for DRF compatibility
Infrastructure:
- Docker + docker-compose for backend and frontend
- Nginx reverse proxy for frontend with /api/ forwarding
- Entrypoint with auto-migrate and default admin creation
- SQLite data persisted via Docker volume at /app/data/
Bug fixes from audit:
- Fix frontend referencing non-existent fields (current_month_spending, effective_budget, budget_usage_percent)
- Fix scheduler using naive datetime.now() → timezone.now()
- Fix scheduler reading interval from settings instead of GlobalConfig DB
- Fix docker-compose SQLite volume mounting as directory
- Fix CORS origin with explicit port 80
- Remove dead config (VOLC_ACCESS_KEY/SK, MONITOR_INTERVAL from settings)
- Remove unused imports
