- Fix broken path construction in FSSyncHandler: build_* methods now
return relative paths; sync_watcher uses paths relative to sync base
instead of CWD (was completely non-functional in production)
- Fix SSH connection leak in push-pull task: conn.close() now in finally
- Add log.warning for disabled SSH host key verification
- Fix race condition in session operation counter: use atomic SQL
increment instead of read-then-write
- Extract _increment_session_counter helper, add exc_info to warnings
- Replace legacy session.query() with select() in sync_sessions_handler
- Fix orphaned session: trigger_push_pull now passes session_id to job
- Fix wasteful SSH download when no matched_save exists
- Fix BaseModel import collision in sync.py (pydantic -> project base)
- Fix ORM mutation in UserSchema.from_orm_with_request: set field on
schema instance instead of mutating live ORM object
- Mask ssh_password and ssh_key_path in DeviceSchema API response
- Fix migration PostgreSQL compatibility: condition ON UPDATE clause
on MySQL, drop enum in downgrade
- Rename copy-paste artifact rom_user_status_enum
Implement device registration and save sync tracking to enable
multi-device save management with conflict detection.
- Device CRUD endpoints (POST/GET/PUT/DELETE /api/devices)
- Save sync state tracking per device
- Conflict detection on upload (409 when device has stale sync)
- Download sync tracking (optimistic and confirmed modes)
- Track/untrack saves per device
- DEVICES_READ/WRITE scopes for authorization
