Synthetic example. Deterministic fictional records; not transformed, aggregated or disguised customer data. Values demonstrate the method, not achieved results.

How to read this scene. One fictional payment retains identity while four system witnesses appear.

Trivial baseline

Coarse matcher: amount and date agree, so the payment is treated as reconciled.

Sensitivity

Extend the settlement maturity window and toggle destination, category and status dimensions; timing-only differences shrink while wrong postings remain.

Strongest counter-case

A difference may be timing, while a match on amount and date may still hide a wrong account.

Verdict

SURVIVES: destination-aware exception. DOWNGRADED: gross exceptions are not recoverable savings.
