# Slot: surrogate 


_Optional permutation-significance test: this derived variable's value is the exceedance p-value of a named statistic under permutations of a field (a general surrogate null — any permutation test, not wave-specific — emitted as a vmap-fold over the captured permutations; the wrapped statistic stays symbolic). When set, the variable's own ``equation`` may be omitted._
