Final coverage assessment — None of the gathered sources discuss the economic principles of rational spending under a hard budget. They cover agent payment infrastructure (S1), stablecoins as a unit of account (S2), an agent trading platform (S3), and ontologies (S4). While S2 mentions budgets and stable units of account as a precondition, it does not address utility maximization, marginal analysis, prioritization, or cumulative spending limits. Therefore, the evidence is insufficient to support any of the sub-claims.

The provided sources do not support the specific rational-spending rules listed (utility maximization subject to budget, marginal benefit/cost comparison, marginal-utility-per-cost prioritization, or cumulative budget enforcement). The only directly relevant statement is that an AI agent needs a stable unit of account to make rational spending decisions: "Dollar stablecoins like USDC let an agent price expected value against cost in stable terms, which is a precondition for rational spending decisions" . The other sources describe payment rails, trading permissions, and ontologies; none of them define how an agent makes rational spending choices under a hard budget. Therefore, based strictly on these sources, the subclaims are unsupported except for the general precondition that value must be priced against cost in stable terms.
