Printer investigation (park-buzi): cover-open on the USB thermal printer wedges its status offline/faulty, surviving a full reboot, recoverable only via `docker restart server`. Traced sendRawUsb/ probeUsb end-to-end — no persistent handle in the app layer, so the leading theory is the container's /dev/usb directory bind-mount retaining a stale view across the printer's physical re-enumeration. Not yet confirmed on hardware; documented with repro/confirmation commands and ranked candidate fixes. Also registers a new lab bench box, "art-docker-station", as a Komodo Stack (dev tier, same shape as park-lab, its own isolated secret refs).
