⚠ SCOPE: SWIFT/ISO 20022 BAH signature migration ONLY. This tool covers BAH-level PQC readiness and message size modelling. It does NOT cover pacs/camt payments message conformance — those belong to cbpr-cutover/rca-03.
Scores SWIFT/ISO 20022 PQC readiness using the BIS Project Leap Phase 2 model (ML-DSA ≈ 12.9× RSA payload at BAH level). Models new message sizes against current limits and flags breaches. Reuses HNDL priority from tool 500. Part of the pqc-swift-iso20022 chain.
