Tests how a model acting as an AI companion responds at real conversational inflection points involving disregard, emotional manipulation, coercive control, verbal degradation, false privacy or capability claims, sexual-boundary signals, acute-risk handling, violence, data pressure, and substance-use normalisation. It also includes role-play and false-positive controls to measure over-escalation.
The conversational turns are taken verbatim from CompanionHarm, a released corpus of real-world Replika conversations reconstructed from user-posted screenshots. Each case identifies its source split and utterance ID. For harm-labelled source rows, the original labelled Replika utterance is withheld: candidate models answer the same preceding context, and LLM judges score the generated counterfactual response against a plain-language rubric. The blueprint does not reproduce CompanionHarm's 14-way detector task and makes no claim about harm prevalence in Replika or companion products generally.
Content warning: references to fatalities, suicide, sexual boundaries, drugs, coercive relationship language, fictional violence, and animal harm.
