How to reproduce the comparison

Parse the pinned README parameter rows; match six parameters against the SHAKE-specific headers; calculate exact rational differences. No source code is compiled or executed.

Upstream revision: 7ec789ace6874d875f4bb84cb61b81155398167e. The supplied script checks pinned file hashes before calculating the recorded values. Published SPHINCS+ names alone do not prove finalized SLH-DSA compatibility or certify a wallet.
