GID-WEB-001SHEET 6 · LOCAL SANDBOX — BROWSER TEST BENCHREV 2ca48122026-07-10
Local sandbox.
Nothing uploads.
View an OBJ or STL part and compute its file digest — entirely in this browser tab. Files are parsed locally; nothing is uploaded. The production engine is demonstrated in pilot evaluations.
STEP 1 OF 2 — SCOPE OF THIS BENCHPreview only
- ▸Renders your mesh in a WebGL viewer — the file never leaves this machine.
- ▸Computes a SHA-256 digest of the file bytes — labeled as exactly that, nothing more.
- ▸Does not run the production engine. Production Gauge.IDs are certified under a declared policy; see them in a pilot evaluation.

SECTION 02SCOPE — THIS SANDBOX VS THE PRODUCTION ENGINEREV 2ca4812
The sandbox shows the problem. The engine is the instrument. What each computes:
| Property | This sandbox | Production engine |
|---|---|---|
| Where it runs | In this browser tab — files parsed locally, nothing uploaded | On your hardware or ours |
| Input | A single OBJ or STL file | A sample of your library — mesh (STL, OBJ) and B-rep (STEP) |
| Output | SHA-256 digest of the file bytes, vertex and triangle counts | A canonical Gauge.ID per part, duplicate and near-duplicate findings, a signed replayable report |
| Pose and format | Rotating, moving, or re-exporting the part changes the digest | Identity is invariant to translation, rotation, and reflection — stable across pose, format, and export path |
| When not certifiable | Not applicable — no certification is attempted | Flagged for engineering review, never silently guessed |
| Certification | None. A preview, labeled as such. | Certified under the declared policy — run it twice, the bytes match. |
The digest changes. The identity should not.
That gap is the instrument's job. A pilot audit runs a sample of your library under a declared policy and returns a signed, replayable report — run it twice, the bytes match.
