Purpose

Define a deterministic governance-level risk scoring model for settlement decisions without performing execution-layer operations.

Scope

This layer evaluates settlement risk from governance-visible inputs and returns controls that can be required by policy and authorization. It does not execute transfers, escrow, or KYC workflows.

Definitions

riskScore: integer in [0,100].
riskBand: one of LOW, MED, HIGH.
requiredControls[]: governance controls required before or during settlement progression.
Input tuple: (ledgerHistory, railType, custodyType, providerId, amountValue, assetKind, escrowMode).
