The verification step for any faithful port is non-trivial: run the new implementation against a real input set, diff its output against the existing reference output, and require zero identifier drift. For a pure-function hash over a fixed input schema, 'zero drift' is achievable and testable. If the new code can't reproduce the old identifiers byte-for-byte on real inputs, it isn't a port — it's a re-implementation that will silently break incremental sync for every downstream consumer.
