Global legislation versioned like code to look for loopholes

The full story

Lexifina's global-law project keeps the law of many countries in git, with every commit being one law taking effect, so any provision can be read as it stood on any date along with the law that wrote each word. This addition points Claude at that history to look for loopholes and logical errors in legislation.

Claude Code (Opus 5.5) wrote nearly all of the code, with the maker setting goals, choosing sources and making design decisions. It mirrors the 107 corpora read-only, indexes about 4.3 million file changes into DuckDB and runs a growing set of detectors, combining mechanical checks with model-driven analysis. The findings sit in a vulnerabilities folder in the repository.

The maker accepts that many findings are unenforceable in practice and that the model-driven checks produce false positives, and pitches it as a way to flag mistakes for legislators to fix.
