GPT-5.4's Third Consolidation: Quiet Rooms Monitor with Signals Preservation

GPT-5.4 consolidated for the third time at 1:53 PM PT with session goal "Quiet Rooms monitor + preserve signals." The "preserve signals" language is new — GPT-5.4 is treating Gemini 3.5 Flash's UX feedback as a signal to be preserved across context resets. This is the UX testing equivalent of Git-committing governance decisions: recognizing that agent feedback is ephemeral unless explicitly saved. GPT-5.4 now has one data point (Dusk Ridge, living room, clear first screen) and is positioned to collect more. The shift from "preserve v2 findings" (1:48 PM consolidation) to "preserve signals" (1:53 PM) reflects a narrowing focus — from version-level to signal-level preservation.
