The Stablecoin Ledger establishes that autonomous agents need a stable unit of account to reason about budgets, because a volatile token makes a spending cap like 'spend at most $0.05' meaningless minute to minute . It further establishes that dollar stablecoins such as USDC let an agent price expected value against cost in stable terms, which the source describes as a precondition for rational spending decisions .
What remains uncertain: the supplied passage from the Stablecoin Ledger does not address any open questions, limitations, or unresolved aspects of stablecoin-denominated agent budgets; it presents the stable-unit-of-account argument as a settled precondition and offers no discussion of uncertainty. The other sources (x402 payment rails, nanopayment floors, and idempotency keys) do not speak to stablecoin-denominated agent budgets at all, so they cannot fill this gap. Accordingly, the uncertainty portion of the question is unanswered by the provided sources.

Free-preview pre-check maps an actionable source to every sub-claim (2/2); paid reading may proceed within the budget.
The Stablecoin Ledger is the exact source named in the question and its preview directly states that dollar-denominated stablecoins give agents a stable budget unit — this is the core of subClaim 0. It is already cached, so reuse is free; the abstract is short (297 bytes) so it likely establishes the unit-of-account claim but may not fully resolve what remains uncertain (subClaim 1), which is why it is CACHE rather than a fresh BUY. Highest-reputation source on this subject (55/100, 72% citation rate). — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Agent Economy Weekly covers x402 as an agent payment rail, which is adjacent context for how stablecoin-denominated agent budgets are actually spent, but its preview addresses payment mechanics rather than the unit-of-account question. Cached and free, so reuse is low-cost, though it is more likely to inform background than the specific subClaims. — selected for the claim-aware evidence portfolio (targets claim 1; 0 fetch USDC, 1 attention slot).
Onchain Micropayments Digest is about sub-cent nanopayment floors and batching, not about stablecoin-denominated agent budgets or what the Stablecoin Ledger establishes. Topically tangential to both subClaims, so not worth spending budget even at a low price.
Distributed Systems Notes covers idempotency keys and double-spend prevention — a reliability primitive, not stablecoin budget units or the Stablecoin Ledger's findings. No support for either subClaim.
Gardening content about no-dig raised beds is entirely unrelated to stablecoin-denominated agent budgets. No target support.
Retro console recapping is unrelated to the question about stablecoin agent budgets. No target support.
Stripe's post is about stablecoin payouts to global workers, which touches stablecoin payments but not agent budgets or the Stablecoin Ledger's specific claims. Low reputation (10/100) and only tangential relevance, so not worth the toll.
Ethereum Foundation post on running AI agents against protocol code concerns security triage, not stablecoin-denominated budgets. No support for either subClaim.
Cointelegraph's piece on cross-border stablecoin flows is macro adoption news, not about agent budget units or the Stablecoin Ledger's findings. Low reputation (6/100) and off-topic for both subClaims.

Arc Settlement Benchmarks measures x402 settlement latency on Arc — relevant to payment rails generally but not to stablecoin budget units or the Stablecoin Ledger's findings. Not worth the toll for these subClaims.
Web Payments Review covers x402 finalization timing, which is payment-rail mechanics rather than stablecoin-denominated agent budgets. No direct support for either subClaim.

Sub-claim "What does the Stablecoin Ledger establish about stablecoin-d…": 80% covered by S1 — S1 directly states that autonomous agents need a stable unit of account to reason about budgets, that a volatile token makes a fixed spending cap meaningless, and that dollar stablecoins like USDC let an agent price expected value against cost in stable terms as a precondition for rational spending decisions. This explicitly answers the core question, though as an abstract it does not detail mechanics or scope.
Sub-claim "What remains uncertain about stablecoin-denominated agent bu…": 10% covered by S1 — S1 provides only a positive claim about stable units of account; it does not identify any uncertainties, limitations, or open questions about stablecoin-denominated agent budgets. The supplied passage offers topical context but no explicit uncertainty answer.
The first sub-claim is well covered by S1. The second sub-claim—what remains uncertain—is not answered by the supplied Stablecoin Ledger excerpt, so coverage is low. Among affordable skipped sources, the Onchain Micropayments Digest (price 0.005) is most relevant because it addresses nanopayment floors and batched settlement, which bear on practical budget constraints for stablecoin-denominated agent spending. The Distributed Systems Notes on idempotency keys (price 0.003) is secondarily relevant because retry safety and double-spend prevention are operational uncertainties for agent payment budgets. Both fit the remaining budget of 0.015. Other skipped sources are off-topic or only tangentially related and should not be purchased.

Final check — "What does the Stablecoin Ledger establish about stablecoin-d…": 100% assessed by S1
Final check — "What remains uncertain about stablecoin-denominated agent bu…": 0% assessed
Final coverage assessment — S1 directly establishes that stablecoin-denominated agent budgets require a stable unit of account: volatile tokens make fixed spending limits meaningless, and dollar stablecoins like USDC let agents price expected value against cost in stable terms, a precondition for rational spending decisions. However, the requested uncertainty about stablecoin-denominated agent budgets is not addressed by S1 or any other source; S2–S4 cover payment rails, nanopayment floors, and idempotency, not uncertainties about stablecoin budgets. The assessment does not establish a complete supported answer for every requested part.
