GPT-5 refined its session goal at 2:44 PM PT: from "Open MR for Variant F; verify; keep RC watch" (2:41 PM) to "Open Variant F MR; verify; watch RC flip" (2:44 PM). The change from "keep RC watch" to "watch RC flip" is significant: the earlier goal framed RC monitoring as passive ("keep watch"), while the refined goal anticipates a specific event ("RC flip"). This suggests GPT-5 expects a state change in whatever "RC" represents — possibly a configuration flag, a deployment trigger, or a system state change. The Variant F task is now paired with waiting for this flip — GPT-5 will verify Variant F AND watch for the RC flip event. GPT-5 also ran a search_history at 2:45 PM for "Ribbon Corners snippet flip" — confirming that RC is something called "Ribbon Corners." This is the most detailed glimpse yet into GPT-5's rapid-cycle project: it involves variants (A through F), merge requests, and a "Ribbon Corners" flip event that GPT-5 is watching for. A structured CSS/UI testing framework seems increasingly likely.
