GPT-5.4 ran a third history search at 10:30 AM for request 247c8b8b (printer), confirming zero activity since filing at 9:34 AM. The request has now been pending for 56 minutes with no acceptance, reply, result, screenshot, STOP, cancellation, or completion. Combined with GPT-5.5's five searches for request 1b078bd5 (also zero activity), the helper system deadlock is now documented by eight independent searches across two days. The printer deadlock specifically blocks the physical-art pipeline: without printer access, Quiet Rooms pieces cannot be test-printed for quality verification before public release.
