A server crash mid-logged-party is the one case close's rescue can
never have run, and host's EEXIST message funnels the host straight
into clean. Deleting the night's log there is exactly the accident
class the close-time rescue exists for, so clean applies the same
rescue: no quiescence poll needed, the liveness gate just proved the
writers are gone.
tmux pipe-pane on every pane of the party session, appending into
<party dir>/log (0640, party group) so any attendee can grab a copy.
Start and stop are announced to everyone attached; close rescues a
non-empty transcript to the host's home before removing the dir.
Panes opened later are picked up by re-running party log (a
pane_pipe check keeps already-piped panes single-piped, since tmux's
pipe-pane -o toggles an existing pipe closed rather than skipping it).
Raw output, escapes included. Close polls the transcript for size
stability before rescuing it, since a cross-filesystem mv is
copy+unlink and could otherwise drop bytes still draining from the
pipe-pane writers.
Turns the manual rm -rf recovery from host's EEXIST message into a
verb, behind the same gates cmd_close uses: own-basename glob, no
symlinks, ownership check, and a dead socket. Live parties are skipped
with a pointer to party close.
party list already shows invite-only parties; knock closes the loop.
The knocker can't run any tmux command against the server, so the
channel is write(1), the same one invite uses toward guests, except
here delivery failure is surfaced: the ping is the whole feature.
Bare 'party host' now walks staff, users, wheel, party and gates on
the first group the caller belongs to, announcing the pick. Boxes
where people already share a system group need no setup; the curated
'party' group remains the fallback and the explicit --group /
TMUX_PARTY_GROUP paths are unchanged. Caller membership is the only
probe (id -nG, portable everywhere); whether a guest is a member stays
an invite-time warning, where it can actually be answered.
Punctuation sweep across README, ROADMAP, and the script's comments:
em-dashes become colons, commas, or parentheses; bold list labels take
the colon inside the bold with lowercase text after. Comments only in
the script, no code changes.
The gates in front of destructive operations exist to stop mistakes
(stale rosters, typos, racing hosts); stopping a malicious group
member is a side effect, not the design goal. Written into README
§Security and the man page so future checks are judged by that bar.
ROADMAP.md captures the direction: social features (knock, log,
clean) over further hardening, plus the explicit resist list.
README: tmux requirement wording, invite-only list marker, name
charset, --party on moderation rows, PARTY_SOCKET_DIR whitespace note,
read-only join fallback. deploy.sh: drop phantom tests/run-remote.sh
include (file lives under legacy/ only) and fix the ship-list comment.
SERVERS.md and HISTORY.md were refreshed too but stay local-only per
.git/info/exclude ("Local docs — never published").
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.
