Re-evaluate

Sub-claim "How does Circle's Gateway settle sub-cent USDC payments?": 10% covered — The sources provide general context about USDC settlement speed and x402 batched settlement latency, but do not mention Circle's Gateway or explain how it settles sub-cent USDC payments. No specific mechanism or details are provided.

Re-evaluate

Coverage is very low (0.1). The skipped source 'Onchain Micropayments Digest' directly discusses batched settlement and sub-cent payments, likely explaining how sub-cent USDC payments are settled. The 'Web Payments Review' source provides an overview of x402 settlement timing, which may include details on Gateway. Both are affordable within the remaining budget.

Sufficiency

Final check — "How does Circle's Gateway settle sub-cent USDC payments?": 10% assessed by S1, S3

Sufficiency

Final coverage assessment — The sources discuss settlement latency and batching but none describe how Circle's Gateway specifically settles sub-cent USDC payments. S1 mentions Gateway-batched payments on Arc but not sub-cent mechanics; S3 discusses batching micro-authorizations but not Circle's Gateway; S2 and S4 are general and not specific to Gateway or sub-cent.

The provided sources do not contain any information about Circle's Gateway or how it settles sub-cent USDC payments. Source S1 discusses Arc's x402 batched settlements and BFT consensus, but does not mention Circle's Gateway. Source S2 describes USDC settlement in general, but not Gateway. Source S3 discusses nanopayments and off-chain authorizations, but not Circle's Gateway. Source S4 provides an alternative view on x402 settlement time, but again does not mention Circle's Gateway. Therefore, the research question cannot be answered from the given sources.
