Etheorem is an executable formalization of Ethereum's consensus layer in Lean 4. The same definitions run, pass the official conformance vectors at the current fork frontier, and carry machine-checked proofs. Normally the running code, the tests, and the proofs live in separate artifacts that drift apart. Here they're one set of definitions, so a proof and a passing vector describe the same spec.
