# Progress

## Status
In Progress — Backend structural refactoring

## Tasks
- [x] Phase 0: Create submodule directory structure (__init__.py files)
- [x] Phase 1: Model subpackages (tool, config, user, project, system)
- [x] Phase 2: Docker service package split (compose, container, config_staging, tunnel)
- [ ] Phase 3: Service subpackages (instance, config, git, build, terminal, shared)
- [ ] Phase 4: Schema extraction (tool, config, user, project, system)
- [ ] Phase 5: API router subpackages (tool, config, workspace, user, project, system)
- [ ] Phase 6: Auth dependency refactor
- [ ] Phase 7: Frontend reorganization
- [ ] Phase 8: Integration and verification

## Files Changed
- `apps/api/src/services/docker.py` → deleted (split into package)
- `apps/api/src/services/docker/__init__.py` — re-exports all public functions
- `apps/api/src/services/docker/compose.py` — compose generation & commands
- `apps/api/src/services/docker/container.py` — container runtime queries
- `apps/api/src/services/docker/config_staging.py` — file staging into instances
- `apps/api/src/services/docker/tunnel.py` — cloudflared tunnel lifecycle
- `apps/api/src/services/tunnel.py` — thin backward-compat re-export wrapper

## Notes
- All backward-compatible imports preserved via __init__.py re-exports
- `from src.services.docker import X` continues to work for all previously exported symbols
- `from src.services.tunnel import X` continues to work via re-export wrapper
- No behavior changes, pure structural refactor
