Move compute_file_hash, compute_zip_hash, and compute_content_hash from
scan_handler.py to filesystem/assets_handler.py as standalone module-level
functions. This follows the existing pattern for utility functions in
filesystem handlers.
Add order_by and order_dir parameters to get_saves() for flexible
sorting. Supports "updated_at" and "created_at" fields with "asc" or
"desc" direction (default: desc). Enables ascending order for pruning
scenarios.
Add fingerprint-based detection for duplicate device registration with
configurable behavior via new body params:
- allow_existing: return existing device if fingerprint matches
- allow_duplicate: skip fingerprint check, always create new device
- reset_syncs: clear tracked saves when reclaiming existing device
Fingerprint matching uses mac_address (primary) or hostname+platform
(fallback). Returns 409 Conflict with device_id when duplicate detected
without flags, 200 OK for existing device, 201 Created for new.
- Add device registration and save synchronization
- Implement slot-based save organization with datetime tagging
- Add conflict detection for multi-device sync scenarios
- Add content hash computation for save deduplication
- Support ZIP inner-file hashing for consistent deduplication
- Add confirm_download endpoint for sync state management
- Add overwrite parameter to bypass conflict checks
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
