PDF extraction pipeline: system cards are now verifiable evidence

methodologyinfoecosystem

Frontier-lab system cards, model cards and technical reports are published as PDFs, which the archival monitor could hash but not read — so every claim citing one sat permanently unverified. A pypdf-based extraction pipeline now archives their text through the same internal ingest API the monitor uses, making the Claude Opus 5, Claude Sonnet 5, Claude Sonnet 4.5, GPT-5, Gemini, Grok 4.1, Nemotron and arXiv PDFs quotable and checkable for the first time.
