Upload a policy PDF to classify against the SAP catalog
J reads your document, retrieves the closest matching SAPs, and proposes per-section actions: ADD, UPDATE, SUPERSEDE, MERGE, NO-OP, or FLAG-CONFLICT. Approve / modify / reject each in the review queue; approved actions stitch into the policy graph.
Where H derives operational WCIs from a policy, J operates one layer up and works with the SAP catalog itself.
