Modern payment systems report success. But success and truth are not the same thing.
This paper introduces the CIF Framework a measurement and classification system for a specific class of distributed systems failure called Chronological Input Failure. CIF occurs when the chronological integrity of a financial event pipeline breaks down under concurrency and retry pressure, causing ledger state to diverge from financial truth without triggering standard observability alerts.
We introduce three measurable metrics the Causality Violation Rate, the Reconciliation Debt Index, and the Ledger Integrity Score and present simulation results showing a baseline CVR of 8.3% under realistic async payment pipeline conditions.
This is not a theoretical paper. Everything here is reproducible. The simulation is open source. The metrics are computable. The cost model is conservative.
