The only gathered source (S1) is a Cointelegraph abstract about SoFi moving its card program to stablecoin settlement. It contains no mention of "Arc Settlement Benchmarks," no median Arc settlement measurement, no p95 Arc settlement measurement, and no supporting evidence for such claims. Therefore none of the sub-claims are addressed by the supplied text. The assessment does not establish a complete supported answer for every requested part.

Sub-claim "What specific claim does Arc Settlement Benchmarks make abou…": 0% covered — The only gathered passage (S1) concerns SoFi moving its card program to stablecoin settlement with $25B annualized volume; it says nothing about Arc Settlement Benchmarks or any median Arc settlement measurement. The Arc Settlement Benchmarks source itself was skipped, so no median figure or claim is present.

Sub-claim "What specific claim does Arc Settlement Benchmarks make abou…": 0% covered — No supplied passage mentions Arc Settlement Benchmarks or any p95 Arc settlement measurement. S1 is unrelated to Arc latency benchmarks.

Sub-claim "What evidence or support does Arc Settlement Benchmarks prov…": 0% covered — No passage describes methodology, data, or support from Arc Settlement Benchmarks. The skipped Arc source preview mentions 'Benchmark methodology and results for x402 batched-settlement finality on Arc testnet,' but a preview/title is not an answer and was not read.

All three sub-claims are entirely uncovered (0.0). The directly relevant skipped source is 'Arc Settlement Benchmarks — Measuring x402 settlement latency on Arc' at $0.003, which fits the remaining budget of $0.013 and is the only skipped item whose scope matches the question. Secondary candidate 'Web Payments Review — How long do x402 payments take to finalize?' ($0.002) is broader and less likely to contain Arc-specific median/p95 claims, so it is not recommended unless the primary source proves insufficient.

Final check — "What specific claim does Arc Settlement Benchmarks make abou…": 100% assessed by S2

Final check — "What evidence or support does Arc Settlement Benchmarks prov…": 100% assessed by S2

Final coverage assessment — S2 directly states the median and p95 Arc settlement measurements and attributes them to thousands of submitBatch calls on Arc testnet, which supports the claims. S1 is unrelated to Arc settlement benchmarks and provides no coverage.
