Every guest call then failed with GUEST_FAILED until OpenCode restarted. A call that gets no JSON back now lists /tmp with ls -1a. Only when the listing answered, includes ".", and lacks the helper's folder is the helper copied again and the call run once more: Python never started the action, so nothing runs twice. A crash, or a boxd CLI that failed (auth, network, a 503), keeps the call's own error with no copy and no retry. The probe is plain words, so it reads the same whether machine exec runs it directly or through a shell. The fake CLI now runs the copy the plugin uploaded and answers like Python when it is missing, so the host tests can clear /tmp as a reboot does.

A machine under a tenth of its memory or over four load per CPU answers GUEST_UNRESPONSIVE with the facts, and its one next step is to tell the user. A machine with nothing on the OpenCode port answers GUEST_SERVER_DOWN, whose next step is boxd_job. A machine that looks well keeps TIMEOUT, with the facts; a probe that does not answer, or answers with a line that is not JSON, keeps the plain timeout.

On a running machine boxd_job now adds lastText, the newest assistant message's text parts, redacted and cut to 300 characters on the laptop; lastActivityAt, the latest of the session's and that message's times; and pending, the user items in the session's inbox. Each is read from the guest's own session with no model call, and left out when the guest does not answer it. A message of another kind than the one asked for is never read as an answer. boxd_submit reads /api/session/active before the prompt and answers queued: true when the session was running, so the prompt waits in its inbox for that run. That read is best-effort: a server that refuses it still takes the prompt.
