partmode-contributor-demo.mp4 and partmode-contributor-demo.gif are an
18-second capture assembled from verified browser states of public source
snapshot 8db0b80417a494e5b3073c25fc02e0c34e171caa on 2026-08-10.
The capture ran the repository locally at http://127.0.0.1:4401. It did not
use the separately deployed PartMode site. The flow used:
- the editable Starter plate template;
- a human width change from 40 mm to 52 mm, committed as revision 1;
- a real
partmode.cad.agent/v1loopback session inpreview-requiredmode; - a detached, exact preview changing
hole_diafrom 8 mm to 18 mm; - the visible human approval dialog;
- OpenCascade kernel and renderer settlement at revision 2; and
- export of one named STEP body in millimetres.
No test-only pairing helper or prerecorded agent transcript was used. The social preview uses the verified exact-preview frame from the same capture.
