- The audit reports 36% byte-identical copies across 18,041 skills and separates static flags, model judgments, and human reading.
Field notes
The census records files at the commits examined and publishes the questions used for model judgments, allowing readers to inspect the evidence rather than relying on a single summary score. Its safety workflow narrows the expensive stages: static checks first, Jev's typed judgments next, then human reading of the highest-ranked bodies. The homepage reports 4.2 million tokens and 93 seconds for 545 full-text reads, alongside a separate count of 557 plugin manifests.
