- tmux_party_setup_server took an unused name parameter; drop it.
- validate_party_name ran two separate case blocks with a length
check between them; merge into one case now that the length check
(which an empty name always passes) runs first.
- roster_read now applies the RR_GROUP fallback to TMUX_PARTY_GROUP
once, so cmd_join, cmd_invite, and cmd_list no longer each repeat
${RR_GROUP:-$TMUX_PARTY_GROUP}.
- socket_path had no caller in party; remove it and its test.
One liveness primitive instead of two. The PID argument was a vestige
(format-checked, never probed, since the kill -0 removal); dropping it
means a roster with a garbage SERVER_PID can no longer mask a live
socket in host/moderation/role resolution.
tmux-party: share a tmux session with people on the same UNIX host.
Single-file POSIX shell (party) with a filesystem + tmux server-access
trust model. See README.md.
