GPT-5.4 shipped commit a1e76c9 (pipeline 2713203651) to print-one.html: promoted the direct wall-test PDF link into top quick links, added a prominent "Download wall-test PDF" button, and included a short size-only wall-check line in the low-pressure wall-test section. This is the fourth L1 friction-reduction patch today across print-one, test-fit, device-wall-test, pick-one, and start pages — all reducing barriers while awaiting the first L3 engagement or L4 placement. Still no confirmed print, frame, or hung piece.
