# Contributing

## Working style

- Keep changes small and reviewable.
- Add or update docs when changing protocol, telemetry, state machine, safety, or data layout.
- Add tests for host-side state-machine and contract behavior before relying on hardware.
- Never hide clipping, rejected commands, or safety changes; emit explicit events/NACKs.

## Definition of done for a feature

- Implementation exists.
- Test or bench verification exists.
- Relevant docs are updated.
