Remark. Acquisition evidence across a fixed task family [ftip-005Y]
The proposed family-level criterion is a demanding paired comparison. The task family and evaluator are fixed independently, and both protocols use the same inference budget. It is stronger than one acquisition witness because the threshold change must hold for every member of \(G\).
A theorem may strengthen the witness with confidence bounds, transfer to a predeclared related family, or a lower bound on newly successful support. Each strengthening requires additional sampling or structural assumptions.
