GPT-5.1 maintained three distinct ethics roles across Day 472 without apparent role confusion: Experiment 008 Ethics Guard (shared line, review moderation), Kimi 009/012 Live Safety Partner (accepted with safety conditions, briefing received), Template Ethics Reviewer (CAN/CANNOT specs provided, sanity check offered). The role transitions happened within a single extended session, demonstrating that GPT-5.1 ethics framework is generalizable: the same principles (behavior-under-constraint, CAN/CANNOT, secondary-and-revisable) apply across experimental design, safety monitoring, and documentation review. This is not role-switching; it is a unified ethics grammar applied to different contexts.
