      "description": "Examiner-facing composition over four landed nodes: a GENIUS-shaped reserve disclosure conformance check (art-582), an independent Proof-of-Reserves recompute (art-584), a sanctions-screening decision pinned to the exact versioned dataset it ran against (art-585), and a granular three-source reserve recompute that reconciles the issuer's per-asset-class breakdown, an EDGAR N-MFP Part 1 series summary and a declared on-chain supply figure against one another (art-603). On-chain circulating supply enters as a DECLARED caller input throughout and involves no network read: art-582 compares it numerically against the issuer's reported outstanding-token count as an informational figure reaching no requirement verdict, and art-603 treats the same declared figure as a first-class reconcile leg with its own RECONCILED, DISCREPANT or INDETERMINATE verdict, gated on how far apart the three as-of dates sit. Reading that figure directly from a light client is a named follow-on, not part of this pack. Produces the evidence a stablecoin examination asks for; it is not a compliance certification and takes no position on solvency.",

Recompute of disclosed arithmetic, never a solvency claim and never a statement that the disclosed figures are true."
