- Fixed kernel-to-Emacs communication bridge.
- Resolved boot-time crashes in multiple skeletal skills.
- Refined Chat skill prompt to eliminate conversational filler.
- Updated Emacs UI to automatically clean up status markers.
- Synchronized all fixes via Literate Org-mode documents.
- Verified physical two-way interaction via simulation.
