Problem
Finance reconciled transactions manually in Excel against a provider’s registry.
Approach
Match amount, fee and status directly from the CDC lakehouse with read-only access. Queue, totals and exception views let finance review differences and record expected amounts in an append-only Iceberg table. 31 synthetic scenarios guard the logic in CI.
Measured outcome
2 people × a full working day → 1 person × less than 30 minutes
