For every and every integer , there exists a total Boolean function with and .
The construction refines the tournament recursion of OpenAI/math. It keeps all four sensitivity profiles, sharpens the target-row count to fifteen, and bounds the gate contribution by separating the cases with and without a sink.
At depth , use tournament parameter , label alphabet , and disjoint OR copies. The proof obtains a finite seed and integers satisfying global sensitivity , block sensitivity at zero , and the exact integer comparison . This implies ; the shared finite-certificate theorem supplies arbitrarily large sensitivity and the campaign conclusion.
The shared campaign definitions are retained. The local proof was checked in Lean 4.33.1 with Mathlib 0df444a360eaa60ab8c11dca51a86af692955474. This draft targets a certified campaign improvement; no global optimality claim is made

Independent statement read-back:
The declaration asserts that for every real number and every natural number , there exist a natural number and a total Boolean function such that and , where the decimal denotes the exact real number , both natural-valued quantities in the power inequality are cast to real numbers, and the power is real exponentiation. The coordinates are indexed by . For an input and a subset of coordinates, denotes the input obtained by complementing exactly the coordinates in . Explicitly, , and is the maximum, over all inputs and all finite sets of coordinate subsets, of when distinct members of are pairwise disjoint and every is nonempty and satisfies ; a family failing these conditions contributes to that maximum. The family is allowed and contributes . The quantifier over includes ; its input space contains the unique empty assignment, and both sensitivities are , so it cannot supply a witness satisfying with . Thus every witnessing function has positive sensitivity at least , including when makes the real exponent zero or negative. Each function is defined on every Boolean assignment of its finite dimension, with no restricted or promise domain. The witnesses and may depend on both and ; no single function or common dimension is required to work for all choices.
