Direct investigations involving rejected, failed, cancelled, expired, duplicate, missing, delayed, misdirected, or incorrectly valued instructions; manage authorized pre-COMMIT cancellation and adjustment processes; and ensure any post-COMMIT return of value is processed as a separately authorized and correlated payment rather than as an in-place reversal. Create a tiered reconciliation framework and enforce the authoritative-record hierarchy across the Ledger, network settlement records, participant positions, settlement instructions, Custodian records, bank-account activity, participant confirmations, and internal accounting records, including controlled disposition of breaks where sources do not agree.
