Field notes
The draft schema separates statements by kind and origin, points to files or records by reference, and can mark facts for revalidation before an action. Its sample case follows a duplicate annual-renewal charge, with one charge identified as a retry duplicate and a refund approval still pending. The page also links a specification, examples, a conformance suite, and a 15-page white paper.
