AEMB: Canonical Protocol-Graph End-to-End Conformance for Hybrid Financial Protocols: Twelve Parent FIA Cases, Additive Venue and Legal Controls, and Registered Evidence Derivations

AEMB v0.1.0 provides 38 deterministic scenarios for event-margin accounting, venue-adapter boundaries, and operational faults. This paper documents AEMB v0.2.0, an additive conformance benchmark with twelve parent Financial Interaction Assertions (FIA-001-FIA-012), four additive venue cases, and one legal/custody no-go case outside the FIA denominator. FIA-011 contains two mandatory subcases. The benchmark registers fourteen negative-control specifications; its bundled generic validator reports four defined checks, while a per-ID all-fourteen execution campaign is not part of this release. Two clean, network-disabled deterministic package reconstructions are byte-identical. The public FIA companion records a local twelve-parent cohort with 84 retained ACTUAL_EVIDENCE positions and registered derivation/correlation metadata; a selected ordered replay is bound to its retained archive. The later frozen-candidate audit separates 55 top-level case specifications and fourteen registered negative controls from four executed generic mutation checks. It does not establish identity-bound semantic execution of all fourteen controls. These results are bounded: evidence positions are not independent runtime systems, raw runtime payloads are not distributed, and the benchmark does not establish production, live-venue, custody, legal, external-settlement, or general financial-protocol conformance.
