## Error Codes

### State Management Errors

- `E_INVALID_TRANSITION` - Invalid state transition
- `E_COMPONENT_NOT_FOUND` - Component not found
- `E_STATE_LOCKED` - Component state is locked
- `E_VALIDATION_FAILED` - State validation failed

### Component Registry Errors

- `E_COMPONENT_EXISTS` - Component already registered
- `E_INVALID_TYPE` - Invalid component type
- `E_DEPENDENCY_MISSING` - Required dependency not found
- `E_CIRCULAR_DEPENDENCY` - Circular dependency detected

---

## Performance Considerations

- State transitions use file locking (`flock`) for atomicity
- RPC methods have retry logic with exponential backoff
- State history is limited to 100 entries per component (configurable)
- Component list queries are cached for 30 seconds
- Bulk operations use Promise.all for parallel execution

---

## Security Considerations

- State transitions require proper authentication
- Frozen components cannot be modified without admin privileges
- System-critical components have additional safeguards
- All state changes are logged with reason and timestamp

---

## Migration and Compatibility

- Existing RPC methods (`get_appstore_apps`, etc.) remain functional
- State-aware methods are additive, not breaking changes
- Components without state entries default to 'available'
- Migration script auto-initializes states for existing components
