Sub-claim "Stablecoins provide immediate transaction finality on blockc…": 80% covered by S2, S3 — S2 states USDC settles instantly onchain with finality; S3 demonstrates sub-second finality for x402 (stablecoin-based) payments.
Sub-claim "Smart contracts enable conditional and automated settlement,…": 30% covered by S2 — S2 mentions programmable settlement but does not explicitly discuss smart contracts or conditional logic.
Sub-claim "Stablecoins maintain a stable value, minimizing volatility r…": 90% covered by S2 — S2 directly explains that stablecoins like USDC provide a stable unit of account for agents, avoiding volatility.
Sub-claim "Autonomous buyers can program payments to release only upon …": 20% covered — No gathered source discusses conditional payment release based on fulfillment of predefined conditions.
Coverage for claims 2 and 4 is below 0.5. Purchasing sources on smart contracts and conditional payments from authoritative platforms (Ethereum Foundation Blog, Vitalik Buterin's website) is likely to fill these gaps within the remaining budget of 0.02.

Synthesizing a grounded answer from 8 source(s)…
⚖️ Sources disagreed on x402 settlement latency — S1 about 15 seconds vs S3 sub-second (median 178ms, p95 240ms) → trusted S3 (S3 provides concrete measurements from testnet, while S1 is based on general reading assuming Ethereum L1 block time.)
