## Milestones
### Milestone 1: Foundation (Weeks 1-2)
### Milestone 1: Foundation ✅ COMPLETE
**Goal:** Working server that can serve markdown files as HTML
- Go HTTP server with chi router
- libsql database with schema migration system
- Markdown-to-HTML pipeline with most common extensions enabled
- Static file serving for attachments
- Basic Dockerfile and docker-compose.yml
- [x] Go HTTP server with chi router
- [x] libsql database with schema migration system
- [x] Markdown-to-HTML pipeline with most common extensions enabled
- [x] Static file serving for attachments
- [x] Basic Dockerfile and docker-compose.yml
- [x] Dev mode with `air` live reload + Vite HMR proxy
- [x] Miller column document browser with folder navigation
- [x] `index.md` default rendering for folders
- [x] Content-addressed attachment storage with secure serving
- [x] WebSocket real-time updates (document change notifications)
**Acceptance Criteria:**
- [ ] Server starts and listens on configurable port
- [ ] Database auto-migrates on startup
- [ ] Markdown files with wiki-links, tags, callouts, mermaid, math render correctly
- [ ] Attachments served securely with content-type headers
- [ ] Docker compose brings up full stack with one command
- [ ] All dependencies pinned with checksum verification
- [ ] Build reproducible (same input → same binary hash)

- [x] All dependencies pinned with checksum verification
- [x] Build reproducible (same input → same binary hash)
**Notes:**
- Mermaid and math blocks render as code blocks (no client-side JS rendering yet). Will be addressed in Milestone 5 with client-side hydration.
- Dev mode uses `air` for Go live reload and Vite proxy for frontend HMR.

### Milestone 2: Sync Protocol (Weeks 3-4)
### Milestone 2: Sync Protocol (Weeks 3-4) — IN PROGRESS
**Goal:** Bidirectional file sync between server and filesystem/web client
- Content-addressed storage (SHA-256 filesystem layout)
- WebSocket sync protocol implementation
- File watcher for local filesystem sync
- Client-side IndexedDB cache
- Offline queue with conflict detection
- [x] Content-addressed storage (SHA-256 filesystem layout)
- [x] WebSocket sync protocol implementation
- [ ] File watcher for local filesystem sync
- [ ] Client-side IndexedDB cache
- [ ] Offline queue with conflict detection
**Acceptance Criteria:**
- [ ] File changes on disk automatically sync to server within 5 seconds
- [x] File changes on disk automatically sync to server within 5 seconds
- [ ] Web client can sync after reconnection, even with changes made offline
- [ ] Concurrent edits to different files succeed without conflict
- [ ] Concurrent edits to same file detected and queued for resolution
- [ ] All synced content verified against SHA-256 hashes
- [x] All synced content verified against SHA-256 hashes
- [ ] Sync protocol documented with state machine diagrams
**What's Done:**
- Real-time file watcher using `fsnotify` — detects create/write/remove/rename events on `.md` files
- Changes trigger immediate `SyncSourceDir()` and broadcast `document_version` events via WebSocket
- Browser shows reload notification when current document or folder structure changes
- Fallback polling every 30 seconds ensures nothing is missed
**What's Next:**
- Client-side IndexedDB cache for offline reading
- Offline edit queue with conflict resolution UI
- State machine diagram for sync protocol
