The paper proposes operationalized metrics (Refusal Elasticity, Prompt Invariance Index, Adversarial Persona Robustness) for detecting lock-in and governance triggers for safety monitoring, with implications for both engineered lock-in (deliberately consolidating beneficial identities) and spontaneous lock-in (misaligned identities hardening during scaling).",
