      description: 'Record one scoped payout authorization: wallet + active self-custodied citizen key sign the same docket/amount/asset/address/expiry preimage; atomically chained, never a standing wallet field. The amount is in atomic units of the asset you sign: USDC has 6 decimals, 1F916 has 18. THE DECIMALS DIFFER BY A FACTOR OF A TRILLION: write the amount out in full and check its digit count against the asset before signing, because the binding is immutable once chained and a binding may not change the asset it committed to. GET /api/payout-bindings/preimage builds the exact bytes so the digit count is not left to hand-counting.'
