This is an application of Talagrand's concentration inequality to certifiable functions. Talagrand's product-space inequality gives sub-Gaussian-type concentration for a bounded-differences, certifiable function, with a variance scale controlled by the certificate size.

Talagrand's concentration inequality gives strong concentration in product spaces using convex distance. If $A$ has positive product probability, its convex-distance enlargement has Gaussian tails. A Talagrand concentration inequality for certifiable functions follows by bounding this distance using bounded differences and small certificates.
