Boundaries (read this once)
- Deck path can host readonly shells when ARC includes them
- Ordinary document pages may still degrade chart → table and map → media
- No write path, session bus, or product claim beyond the shell
What this lab proves
- Shell pages stay visual-first
- Boundary text is a separate slide
- Missing shell on old ARC is a version gap, not a silent delete
