Computed, not generated — field record SC-D8ECE64B
232mm
One terrace crack. Tape said 227 mm, a photo-alone guess said 315 mm, SnapClaim measured 232 mm [R005] — confirmed by gate, skeptic, and mask cross-check.
Exhibit A
Capture — a phone and a coin
Sample captures from the team's test set. Tap any photo to enlarge it. In the app, you tap the damage and the coin; on-device SlimSAM previews the masks before anything is sent.
Exhibit B
Pipeline — masks to receipts to sentences
No LLM touches the numbers. Models write sentences; deterministic code does the arithmetic. The evidence gate ships a finding only if every number cites its receipt — otherwise HTTP 422 with named failures.
