+Generated: 2026-05-26. Source-refresh: 2026-07-06 for Raspberry Pi 5, AK60, and ordered BiSS-C encoders. This foundation is a repo scaffold and implementation aid,
 not a replacement for the approved P11 source specifications. If this repo and
 the source specs disagree, ask Antoine before changing architecture, safety,
 telemetry contracts, or scope.
