Physical identity, computed locally
Give every object
a verifiable passport.
Import a real 3D scan, compute its 3DPass Grid2d fingerprint on this device, then anchor the evidence digest to Robinhood Chain.

On iPhone
- Scan the complete object with a LiDAR or photogrammetry app.
- Export a closed, detailed mesh as OBJ to Files.
- Return here and choose that file. Use the same scanner settings for rescans.
This PWA does not pretend camera photos are a 3D mesh. Recognition starts only from actual OBJ geometry.

Describe the object
Claims remain local. Only their deterministic digest is anchored.
03
Review and anchor
The passport already exists locally. Anchoring publishes only fixed-length digests and a resolver URL.
What leaves this device
Passport ID, manifest digest, physical-claim digest, method digest, and public resolver URL. The OBJ, photo, serial, location, and notes remain local.
