A Lean 4 formalization proves that value-independence implies identical marginal distributions for masking verification across all positive integers q.
For each ๐ 1, the filter predicate ๐ค(๐ฅ โ ๐ 1, ๐ 1) = ๐ฃ holds if and only if ๐ค(๐ฅโฒ โ ๐ 1, ๐ 1) = ๐ฃ

From Finite Enumeration to Universal Proof: Ring-Theoretic Foundations for PQC Hardware Masking Verification
A Lean 4 formalization proves that value-independence implies identical marginal distributions for masking verification across all positive integers q.
