Definition. A contamination predicate [ftip-00GV]
Given a contamination record \(c(z)\), write \(\operatorname {cont}(z)=1\) when its declared overlap or exposure rule rejects \(z\), and write \(\operatorname {cont}(z)=0\) when the rule clears it. The predicate belongs to the protocol, not to a model’s score.
