pub fn session_dir(name: &str) -> Result<PathBuf>Expand description
Full filesystem path for the named session’s WIRE_HOME root.
Inside this dir the standard wire layout applies: config/wire/...
and state/wire/....
Resolves the legacy v0.6 top-level layout only — joins the
session name directly onto sessions_root. Operator-facing CLI
paths that accept a user-typed session name should use
find_session_home_by_name instead, which also handles the
v0.13 by-key/<hash> layout where the on-disk dir name is a hash
and the user-facing name is the persona handle derived from the
card.
