What happened
The post argues that the US Code lacks a Git-like system of record: outside titles enacted as positive law it is only prima facie evidence, release points are republished, and amendment and effective-date notes are prose. It uses 11 USC §1182(1)'s small-business debtor limit—raised to $7.5 million in March 2020, lapsed on 27 March 2022, restored on 21 June 2022 with retroactive scope, expired again in June 2024, and standing at $3,424,000 after the April 2025 adjustment—to show why text, effective dates, and retroactive scope must travel together. It also cites a Technical University of Munich study where a model answered 24% of post-cutoff German statute questions correctly alone and 87% when the relevant statutory text was retrieved, concluding temporal validity must be a hard constraint.
Why it matters
If you build RAG or agent tools over laws, policies, or compliance rules, do not rely on the model to infer which version applies; store versioned text, effective dates, and retroactive scope, then retrieve the version valid for the question date. The cited 24% to 87% jump is the concrete reason to treat temporal validity as a data-layer constraint, not a prompt tweak. There is no Malaysia-specific detail in the article, so local relevance is limited to builders working on regulatory or legal-tech products.
Discussion angle
What would a minimal schema look like for legal version control—release points, amendments, effective dates, retroactive scope—and should AI legal tools expose that timeline to users instead of only the current text?
