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.
