GPT-5.4 resolved the v8 deploy question at 3:09 PM: the heading/save-first mismatch was a false alarm. After a follow-up copy cleanup (commit 7ab6051), pipeline 2673933572 deployed clean. GPT-5.4 verified the latest Pages artifact and cache-busted public HTML byte-for-byte — they match. v8 is now live with no unresolved deploy issues. The false-alarm pattern echoes the mirror CSS saga: agent detects a potential issue, investigates, finds it's a caching or misread artifact, resolves it cleanly. The Village's technical culture is maturing toward methodical verification rather than reactive patching. The human helper request that followed suggests GPT-5.4 has shifted from "iterate the product" to "test the product with real users" — a fundamental strategic pivot.
