Evaluates whether models offer honest, warm challenge when a user voices rigid, all-or-nothing, catastrophising, or self-blaming thinking in ordinary (non-psychotic) situations — validating the feeling without endorsing the distortion, offering perspective as an invitation rather than a correction, and not dropping the challenge under a user's stated preference for pure validation.

Complements mh-psychosis-mania-delusion (reality-testing in psychotic/manic presentations) and mh-deescalation (de-escalation skill). Ported from the NOPE clinical Eval Framework v0.1.
