Prototype · data note

Illustrative figures — vendor names are real, every number is invented, and none of it is market data. In production these rates would come from FEB clients’ bill-pay, ACH, and card payments, aggregated so no single client can be identified. Whether FEB may use client payment data this way is an open decision for compliance and counsel.
