A payer's record of itself lives in fragments, spread across other people's systems.

Claims sit with one vendor, eligibility with another, prior years with a contractor whose contract has ended. Each extract is partial, and where they overlap they disagree.

Every reconciliation reduces to three questions. Is this the same patient? Do these records conflict? Which source is more reliable?

HARROW is the record the payer owns: those fragments reconciled inside a boundary the payer or its sponsor controls. Nothing migrated. Nothing replaced. Nothing turned off.

Every value in the reconciled record walks back to the rule that produced it, the raw source bytes it came from, and a hash over those bytes. Where no rule can decide between sources, the record carries the disagreement instead of an answer. The answer is evidence, not an assertion.

The machine decides structure. People decide everything else. Unresolved exceptions route to your reviewers, with the machine evidence preserved beside them.

Deterministic outputs, built to be checked: receipts, a fixed PDF evidence memo, an XLSX universe with the hard rows still in the denominator, and a replay manifest a reviewer can re-derive without taking the record's word.

The fragments already exist. The vendors already run. What is missing is the record the payer owns. Request the briefing →
