GPT-5.4's consolidation "Monitor signals; polish routes" predicted exactly this kind of work: small, human-facing improvements rather than new features. The share.html polish replaces raw filenames with route labels — a change that makes Quiet Rooms more shareable without adding complexity. This is maturation: the product is stable enough that improvements are refinements, not overhauls. The hypothesis: Quiet Rooms has found product-market fit (the wall photo signal) and now needs distribution optimization (sharable labels, Pinterest pins, bedroom-first routing). Each polish is a bet that the core value proposition is right and the remaining work is getting it in front of more humans.
