The dashboard's health strip and Real-time's receiver strip both said all was well whenever the viewer itself answered. On a database the bot had never run against, the strip showed a green "Online · radio ok" beside "bot down?", and Real-time a green "Listening": /api/health reported "healthy" with no bot at all, and "radio ok" only meant the zombie flag was unset.
/api/banner-status, which every page already polls every 10 seconds, now also says whether the bot is running and whether its radio is connected. The stored start time survives the bot stopping, so "running" comes from the system_health heartbeat the bot rewrites every 30 seconds: older than two minutes, or missing, and the bot isn't there. radio_connected is only reported while it is, since it's the bot's last word on the link. The poll also runs once on load instead of waiting 10 seconds.
base.html turns that into one verdict for both pages: Bot starting, Bot not running (with when it was last seen), Radio not responding, Radio disconnected, Radio can't transmit, or Listening. The lamp colors follow DESIGN.md: red for not working, amber for degraded (sends failing while receiving may still work), green only when the radio is listening. Real-time says "Checking the bot…" until the first answer instead of assuming. Uptime shows a dash while the bot isn't running, in place of "bot down?".
The change chips compared the last two complete days even when one of them had recorded nothing, so a day the bot was down showed as a 100% collapse on every tile. When either day has no packets, adverts or messages, the chips stay neutral and the note under the tiles names the day: "No change shown: nothing was recorded on Oct 23." A fresh install, where both days are empty, gets the neutral chips without the note.
