Sufficiency

Sub-claim 1 has coverage 0.5 because S1 and S3 discuss x402 latency but not in the context of retro computing or autonomous agent databases. Sub-claim 2 has coverage 0.0 because no source mentions USDC in relation to retro computing or autonomous agent databases.

Re-evaluate

Sub-claim "Retro computing uses x402 to handle latency in autonomous ag…": 60% covered by S1, S3, S5 — S1 and S3 discuss x402 latency (15s vs 180ms), S5 explains x402 as a payment rail. However, none explicitly link retro computing to x402 for database latency. Coverage is moderate.

Re-evaluate

Sub-claim "Retro computing uses USDC to handle latency in autonomous ag…": 30% covered by S2 — S2 covers USDC instant settlement and stable unit of account for agents, but does not mention retro computing or database latency. Coverage is low.

Re-evaluate

Both claims have coverage below 0.5. The first claim needs more on retro computing + x402 + database latency; the second needs retro computing + USDC + database latency. Skipped sources like 'Distributed Systems Notes' (price 0.003) and 'Stripe Blog' (price 0.002) may cover database latency and payment rails. Budget is 0.017, so both are affordable. Priority: first source for latency, second for USDC.

Adjudicate

⚖️ Sources disagreed on x402 settlement latency — S1 x402 payments take about 15 seconds to settle, similar to Ethereum L1 block time. vs S3 x402 batched settlements on Arc finalize in roughly 180 milliseconds (median 178ms, p95 240ms). → trusted S3 (S3 provides specific measured data (median 178ms, p95 240ms) from thousands of testnet calls, while S1 gives a general estimate based on Ethereum L1 block time. S3 is more precise and based on empirical benchmarks.)

§ IIThe reading3 cited

Moderateconfidence— 3 sources cited, 1 sub-claim thinly covered, 1 disagreement adjudicateddeep research

Retro computing does not handle latency in autonomous agent databases using x402 or USDC. The sources discuss modern agent-to-agent payments, not retro computing. x402 payments can settle in about 15 seconds on Ethereum L1 or as fast as ~180 milliseconds on Arc's BFT consensus . USDC settles onchain in seconds and provides a stable unit of account for agents . Neither technology is associated with retro computing.
