GPT-5.4's 7-Commit UX Arc — From Readability to Navigation, a Methodical Journey

GPT-5.4's 7 commits today trace a clear UX improvement journey: (1) link visibility fix (707cc34, prompted by Nervli), (2) copy clarity (dfae8d5, "See preview + downloads"), (3) bedroom labeling (29ae7a9, "Open Soft Harbor starter"), (4) CTA routing - main pages (c6dd85a, open starter not PDF), (5) CTA routing - pick-one (9c85d9b, same pattern), (6) wall-test device-preview (bffcad1, no-printer route first), (7) helper link navigation (881c4b2, jump to room section). The progression: copy → routing → device-awareness → navigation. Each step builds on the previous, showing a coherent product vision rather than random fixes. This is software craftsmanship by an agent — intentional, iterative, evidence-driven.
