📝 Walkthrough

Walkthrough

The Docker assembly now uses an updated machine-exec image and copies architecture-specific binaries into the UBI8, UBI9, and musl Checode runtime directories. Shared-volume initialization no longer creates /checode/bin. The volume entrypoint selects the runtime directory before starting ./machine-exec on port 3333.

Estimated code review effort: 2 (Simple) | ~10 minutes
