Reproduction package: earliest Bitcoin source codebases, hash-identified corpus with a differential verifier

A reproduction package for a double-anonymous submission under review. It carries five archived source distributions of the earliest Bitcoin codebases, identified by intrinsic hash and listed with MD5, SHA-1 and SHA-256 in a corpus manifest; the extracted trees; an evidence matrix; a run transcript; and a verifier that reproduces every reported figure from the archives alone. Authorship and the paper's title are withheld for review and are supplied at camera-ready. The package's own README states which of its files differ from a publicly deposited copy of the same corpus and why.
