An actuary cannot price a promise. Underwriting analysis needs a record: what the policy was, whether it held, how confident the check was, and what the risk signal read. When a payment runs, it also needs where the money went. Solv produces the policy-check evidence at execution time, and records payment destination when payment proceeds — intended to support underwriting analysis.
Two of the eighteen fields — confidence and risk_signal — are written for that reader. The other sixteen are written for the examiner. The plates below open a worked presentation.
