Step 1 simulates the GPI tracker lifecycle for the payment status transition and Universal Confirmation SLA (ACSP to ACCC within 24h). Step 2 scores MT103-to-pacs.008 field mapping fidelity (ordering customer, beneficiary, agent BICs, remittance info, charge bearer code mapping OUR=DEBT/SHA=SHAR/BEN=CRED). Both steps always run.
