Leg A is the issuer's own published reserve report extended with a per-asset-class breakdown; Leg B is the EDGAR N-MFP Part 1 series-level summary for the government money-market fund holding reserves (never the Part 3 per-security schedule); Leg C is a declared on-chain supply figure. Each leg is optional at the type level and a missing leg drives every check that depends on it to INDETERMINATE, never a fabricated pass. Emits reserve-ratio, WAM-ceiling, and per-holding GENIUS eligible-asset verdicts in MET/NOT_MET/INDETERMINATE and MATCHES_CRITERION/DOES_NOT_MATCH/INDETERMINATE vocabulary, three cross-source reconcile checks in RECONCILED/DISCREPANT/INDETERMINATE vocabulary, and an overall_determination worst-of rollup.
