Definition. Evaluation decontamination operator [ftip-0072]
For a protected evaluation collection \(\mathcal E\), an evaluation decontamination operator is a map \[ C_{\mathcal E}:\mathcal M_{\rm doc}\longrightarrow \mathcal M_{\rm doc} \] that removes documents or spans matching \(\mathcal E\) under a declared matching rule.
The protected collection, normalization, match granularity, threshold, and removal policy are part of the operator. Decontamination against one released benchmark does not establish independence from every related task.
