Missing evidence blocks - it's never read as a pass. Real audit finding (Aug 5, 2026): the Brazilian pilot had zero waivers on file, and the engine's earlier version read an empty catalog as "nothing required" - every Guarapiranga trip would have cleared with no one having accepted any risk. The fixed rule blocks by default: an empty catalog is never a waiver, it's always a setup gap.
