# Parser QA (automated cross-check)

Generated 2026-11-03T22:48:57+00:00 (code feb6c9e-dirty). Sample: 26 documents (5 random articles per year, seed 45, + all non-article types). Reference extraction = regex on `pdftotext -layout`; this is a cross-parser agreement check, **not** a human gold standard.
