CAD eval sheet

Fixed-fixture smoke: extract → cad_scene → Rowe on checked-in DXF/STEP parts. Not a public superiority benchmark. Re-run with npm run ops:cad-eval.

What this is

A fixed smoke on checked-in tests/fixtures/minimal-bracket.dxf and tests/fixtures/minimal-bracket.step: extract → wrap four-cad.cad_scene.v1 → POST /api/v1/responses. Results are written to the repo as docs/eval-sheet.md when operators run npm run ops:cad-eval.

What this is not

Not a comparison vs other models, not a manufacturability accuracy study, and not an SLA. See Evidence pack.

Re-run

Terminal

$ npm run ops:cad-eval -- sheehanmunim@gmail.com
$ # or
