- Worth noticing
- Expected outcomes are locked before a run; the page says signatures are withheld automatically when actual results diverge.
Field notes
The described protocol includes machine-readable schemas and separate disclosures for AI authorship, funding, and reviewers. Its example record uses the T1566.001 spearphishing-attachment technique, with “expected” and “actual” outcomes compared before signing. The page presents local or cloud arena testing and a continuous production mode, but access is requested by work email and the supplied evidence does not verify either mode in operation.
