# Sensitivity counterexample generator

Family 132: A superquadratic separation of sensitivity and block sensitivity. First review, 8 October 2026.

## Problem and potential new use

Robustness and Boolean-function researchers can demonstrate that single-bit sensitivity can underestimate disjoint block changes.

## Applicability and commercial boundary

The separation does not quantify real model robustness or provide a general adversarial-example attack.

## Initial business decision

Research infrastructure. Buyer demand and profitability remain hypotheses. This first pass does not establish a validated commercial market.

## Next verification action

Read the construction and implement small instances where both quantities can be calculated exactly.

## Evidence scope
