stackchan-simulator

Add a new servo spec or mass profile to params.py, then regenerate the model and verify. Use when asked to add/support a new servo (e.g. a new Feetech/Dynamixel model) or a new mass profile to the Stack-chan simulator.

Pre-publish OSS compliance check — verifies secrets/artifacts are gitignored, LICENSE/NOTICE/THIRD_PARTY_NOTICES exist, no secrets or personal info are about to be committed, and tests pass. Use before publishing/committing for release or when asked to audit OSS readiness.

Regenerate the committed MJCF snapshot models/stackchan/stackchan.xml from params.py after physical parameters change, then show the diff. Use after editing params.py or model.py.

Visually verify the Stack-chan web UI / on-monitor face by launching the emulator and capturing Playwright screenshots into artifacts/. Use after changing web/ (face_renderer.js, scene.js, app.js, compat.py, contract.py) or when asked to confirm the face/expressions/dashboard render correctly.
