Fraud Detection

Fraud investigation has a recursive problem: the investigation record itself must be beyond suspicion. CueCrux solves the recursive part structurally. Findings, flags, and analyst dispositions all mint signed receipts on the BLAKE3 append-only spine, so the investigation file is tamper-evident: nobody, including an insider, can quietly edit what was found or when. Offline verification means the file's integrity is checkable by counsel, regulators, or enforcement without access to the systems that produced it.

The detection work itself follows the receipted pattern. When agents cross-reference claims against authoritative sources, flag inconsistencies across document sets, or map activity against regulator-published typologies, each flag carries the evidence that raised it. Investigators triage flags with the basis attached rather than re-deriving it, and dismissed flags leave signed dispositions, which matters when a later case asks why an earlier signal was closed.

Attribution runs through everything: every action in the investigation binds to a passport identity and trust tier. When findings graduate into enforcement referrals or court proceedings, the package exports as a verifiable bundle whose chain of custody is the hash chain itself.
