- Make blake3 import lazy in hashing.py (only imported when needed) - Add compute_hashes parameter to AssetSeeder.start(), build_asset_specs(), and seed_assets() - Fix missing tag clearing: include is_missing states in sync when update_missing_tags=True - Clear is_missing flag on cache states when files are restored with matching mtime/size - Fix validation error serialization in routes.py (use json.loads(ve.json())) Amp-Thread-ID: https://ampcode.com/threads/T-019c3614-56d4-74a8-a717-19922d6dbbee Co-authored-by: Amp <amp@ampcode.com>
