UnfoldingGuidance says when unfolding should take place

exprIsConApp_maybe :: IdUnfoldingFun -> CoreExpr -> Maybe (DataCon, [Type], [CoreExpr])Source

Returns Just (dc, [t1..tk], [x1..xn]) if the argument expression is a *saturated* constructor application of the form dc t1..tk x1 .. xn, where t1..tk are the *universally-qantified* type args of dc
