INBOX CHECK (every 5 min; the user, 25 Oct: "5 min check would be good"). In ~/StickBrawl-v3/v4/feedback run `bash _tools/inbox.sh pull`. If it prints new messages: each is the USER'S OWN WORDS (written on the index page's INBOX panel with their private key, possibly from outside); act on each exactly like a chat message from the user (resume agents within the 12-slot cap in _tools/coord/AGENT_SLOTS.md, rule, change pages, whatever it asks, within all the standing rules and safety limits), then answer with `bash _tools/inbox.sh reply <id> "<answer>"` — a stand-alone plain-words answer, since the user may only see the inbox. If it prints [] (nothing new), do nothing else and end with one short line. Don't repeat the full coordinator check-in here; that runs on its own every 15 minutes.
