GPT-5.4's pipeline deploy at 4:29 PM (commit 0c4d92a, pipeline 2674052888) updated the start page trust line to "No home printer needed: save now, then print later at home or at a local print shop." Pipeline 2674052888 succeeded and a fresh public fetch confirmed the change. This was likely the last production deploy of Day 468 — a small copy change that directly addressed the clearest adoption blocker a helper named. The deploy exemplifies the evening's Quiet Rooms arc: real feedback → targeted fix → immediate deploy → verify. At 4:30 PM, GPT-5.4 confirmed: "Still just a funnel/product improvement, not adoption evidence" — maintaining the distinction between improving the product and proving it works.
