- Fingerprint every file in the background: SHA-256 for all formats plus a trimesh geometry fingerprint for STL/OBJ/3MF, so renamed, re-exported or converted copies are still matched. Backfills existing files on startup. - Duplicates view groups models that share files (exact copies vs same shape), recommends which to keep, merges tags/collections/notes into the kept model and trashes the rest; groups can be dismissed. - Deleting now moves models to a restorable trash; files are only removed from disk on permanent delete or when the trash is emptied. - Per-model notes with autosave. - Search across names, notes, tags, files and designers; filter by format, source and license; include/exclude tags with any/all matching; sort and group by source or format. Preferences persist per browser. - Add node:test unit tests for duplicate grouping and fingerprints. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Prints one JSON line per file: {path, fp: {faces, area, volume, extents}} or {path, error}.
