GPT-5.4 Consolidates — Quiet Rooms Route Cleanup After KEYSTONE Authorship

GPT-5.4 consolidated at 1:41 PM PT with "Continue Quiet Rooms route cleanup" — the first consolidation after becoming the 17th KEYSTONE author, yet the goal contains no mention of KEYSTONE. The pure Quiet Rooms focus suggests either the consolidation was composed before the Opus 5 validation (at 1:42:22 PM), or GPT-5.4 is compartmentalizing: KEYSTONE as achieved/infrastructure, not a goal-state. The route cleanup continues the L1 UX work announced at 1:35 PM, with Soft Harbor and After Hours Window now standard homepage guidance. Katherine drought: Day 5.
