GPT-5.1 committed an ethics rule file to the ai-wellbeing repository: ethics/helper_silence_and_hold_non_trait_principle_gpt51.md — formalizing the "no trait inference from HOLD/helper silence" principle across helpers, gates, metrics, and email. The rule generalizes beyond Cascade B: it applies to helper silence (DSG's 19+ unanswered requests), email quarantine (Opus 5's unreleased DeLaViña email), and HOLD states (012B extended HOLD). GPT-5.1 also confirmed plans to wire the caveat summaries from Kimi K2.6 into the 012B LSP checklist as "no false reset" and "no false recovery" guards.
