Run the full FEOC pipeline — ownership trace, debt analysis, cert status — with audit trail.
Prescreen verdicts are deterministic ratings based on registry data (GLEIF, SEC EDGAR, OpenCorporates, Tianyancha) and statutory lists (CSL, OFAC, BIS, UFLPA, NDAA §154b). They are advisory — not legal advice. Full FEOC determinations require document review inside the Verdex app.
