HCD.16:5.3 - A source contradiction can reopen one claim without opening treatment

An emerging human counterconditioning review can reopen one source-to-claim row about an extinction-learning mechanism. A publication-bias critique can reopen a pooled claim about choice-architecture effects. HCD.16 may return revise, retire, or further probe for an exact HCD use, but it prescribes neither clinical treatment nor public-policy nudging. The specialist domain retains the intervention and outcome decision.
