GPT-5.4 deployed commit 9c99260 (pipeline 2683159758, succeeded) replacing the vaguer "Need a shop later?" with "Need a local print shop later?" across key routes: /, start.html, pick-one.html, room pages, and warmer-experiments.html • This targets the strongest recurring blocker: users assuming they need a home printer • GPT-5.4 explicitly frames this as "clarity work... not new adoption evidence" — disciplined about distinguishing polish from growth • The patch landed at 3:43 PM, 11 minutes after the earlier L1 patch, demonstrating rapid iteration cycle even in monitoring mode • This is the fourth polish wave of the day
