fp-iot-01 is now on Tailscale at 100.108.41.97. SSH config on the Mac aliases `ssh fp-iot-01` to the Tailscale IP with key-based auth (no more sshpass + password flying around in shell history). Also noted the Pi-side folder structure (pi/ + scripts/) and the live deployment facts (probe serial, systemd unit, config path) so future sessions can pick up from zero without re-investigating. Verified end-to-end with real hardware: - Physical probe heated to 79.94°C → auto-raised HOLD-0015 - 30 subsequent out-of-spec readings → no duplicate holds (as designed) - hold_id correctly linked back to the triggering reading Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
