# Complete Implementation Plan for Onyx Phase 1
## Milestone 2: Transparent Versioning and onx save ✓ COMPLETED
### Filesystem Daemon Implementation
21.**Create daemon structure** (`internal/daemon/daemon.go`)
- Implemented Daemon struct with repo, watcher, ticker, debounce, and shutdown channels
- Added configuration support with Config struct
- Implemented Start(), Stop(), and IsRunning() methods
- Includes main event loop with proper goroutine management
22.**Implement filesystem watching** (`internal/daemon/watcher.go`)
- Initialized fsnotify watcher
- Added repository root to watch list with recursive directory walking
- Implemented recursive subdirectory watching
- Filtered out .git, .onx, and other ignored directories
- Implemented debouncing (500ms default, configurable)
23.**Implement snapshot algorithm** (`internal/daemon/snapshot.go`)
- Implemented CreateSnapshot() with full workflow:
1. Read current workspace pointer from .onx/workspace
2. Create tree from working directory state
3. Create ephemeral commit with auto-generated message
4. Update refs/onyx/workspaces/current reference
5. Update .onx/workspace pointer with latest state
- Added workspace state serialization/deserialization
24.**Create daemon entry point** (`cmd/onxd/main.go`)
- Implemented command-line interface with cobra
- Parse command line flags (repo path, interval, debounce)
- Initialize daemon with configuration
- Set up signal handlers (SIGTERM, SIGINT) for graceful shutdown
- Run main loop with PID file management
25.**Implement daemon control** (`internal/commands/daemon.go`)
- `onx daemon start` - Start background daemon with process detachment
- `onx daemon stop` - Stop daemon gracefully using SIGTERM
- `onx daemon status` - Check daemon status via PID file
- PID file management in .onx/daemon.pid
- Process lifecycle management with proper signal handling
### onx save Command
26.**Implement save command** (`internal/commands/save.go`)
- Implemented Save() with complete workflow:
1. Read current ephemeral commit from refs/onyx/workspaces/current
2. Create new commit with user-provided message
3. Determine next branch number based on workstream commit count
4. Create branch ref (refs/onyx/workstreams/{name}/commit-{n})
5. Update workstreams.json with new commit metadata
6. Log to oplog via transaction support
- Integrated with existing workstream model
- Added transaction support for undo capability
27.**Add message validation**
- Require non-empty message (enforced by cobra flag)
- Validate message length (max 72 chars for title)
- Support multi-line messages with -m flag
- Proper error messages for validation failures
### Implementation Summary
All components of Milestone 2 have been successfully implemented:
- **Daemon**: Full filesystem monitoring with fsnotify, debouncing, and automatic snapshots
- **Save Command**: Complete integration with workstreams and oplog
- **Infrastructure**: PID file management, signal handling, transaction support
- **Testing**: All existing tests pass, binaries build successfully
The implementation provides a solid foundation for transparent versioning in Onyx.
