Lowconfidence— Contains synthetic demo material; its measurements cannot support factual conclusions.

Lowconfidence— Contains synthetic demo material; its measurements cannot support factual conclusions.deep researchpreview plan 1/1 claimsportfolio 1/1 · evidence 100%

Illustrative demo content: synthetic sources and measurements are not factual research evidence. Source provenance and payment status are separate; inspect the receipt for settled, pending or simulated payments. Settlement does not authenticate a source's claims.

> ⚠ Low confidence — 1 sub-claim remains below the evidence threshold within budget. Treat this as provisional.

The provided source reports that x402 batched settlements on Arc testnet finalize in roughly 180 milliseconds, based on thousands of submitBatch calls, with a measured median of 178ms and p95 of 240ms . It attributes this to Arc's BFT consensus delivering sub-second finality, meaning a Gateway-batched payment confirms in well under a quarter second and is not block-time-bound like an Ethereum L1 transaction . Note that this is an abstract-level source, so it does not provide further implementation details.

Research targets are unverified topics. Coverage is an estimate of excerpt support, not proof of entailment, factual truth or a complete answer.

Research evidence matrix

Compare unverified research targets with cited sources and inspect recorded excerpts. An empty cell means no inspectable excerpt was recorded; it does not establish whether a claim is true, false, or disputed. Coverage and agent confidence do not prove entailment, measured accuracy or complete synthesis.

hiIllustrative demo excerpt
Inspect 2 excerpts
Across thousands of submitBatch calls on Arc testnet, x402 batched settlements finalize in roughly 180 milliseconds (measured median 178ms, p95 240ms).
Arc's BFT consensus delivers sub-second finality, so a Gateway-batched payment confirms in well under a quarter second — it is not block-time-bound the way an Ethereum L1 transaction is.

Re-evaluate

Sub-claim "hi": 0% covered — The research question and sub-claim are the placeholder string 'hi', which has no substantive content. The supplied passage (S1) discusses x402 settlement latency on Arc and does not answer any meaningful question. No requested part is addressed.

Re-evaluate

The question and sub-claim are placeholders ('hi') with no defined scope, so no source can provide a substantive answer and no gap can be meaningfully filled. The only gathered source (S1) is topically unrelated to any real research question. Skipped sources are either unrelated (gardening, retro consoles, esoteric religion, robotics simulation) or, at best, tangentially related to x402/crypto payments; none would answer a placeholder query. Given the absence of a real question, buying more sources is not justified.

Sufficiency

Final check — "hi": 0% assessed

Sufficiency

Final coverage assessment — The question 'hi' is a greeting with no substantive research request. The single sub-claim 'hi' is not a research question and cannot be answered by the supplied source. The source discusses Arc x402 settlement latency, which is unrelated to the greeting. No requested part is answered, so coverage is 0. The assessment does not establish a complete supported answer for every requested part.
