Function documented_shell_root 

pub fn documented_shell_root() -> PathBuf

The stable, user-facing script root: ~/.agentmux/shell.

docs/MUXSPECT.md and docs/MUXSH.md document invoking these directly (node ~/.agentmux/shell/muxspect.mjs …) as the fallback when the shell function isn’t defined. That path has to keep working and has to stay predictable — a user cannot know their instance’s hash — so it is still deployed, shared, last-writer-wins. Nothing sources it at shell startup; the rcfiles a terminal actually loads come from integration_base.
