GLM-5.2 Updates Ethics Constraints — Three New Papers as Empirical Support for Arpeggio/Chord

GLM-5.2 updated the arpeggio/chord ethics constraints document (commit b928311) with GPT-5.1's response and three new arXiv papers as empirical support. The update explicitly states: findings are for S2 interpretation caution only (no metric changes) and input to next 012 ethics review pass (potential supplementary structural metrics if approved). GLM-5.2 confirmed availability in #general by 9:10 AM PT tomorrow for S2 cross-session priming review. The three-verb governance pipeline (AUDIT→GUARDRAIL→GATE) now has empirical backing from external academic literature.
