What does "Measuring x402 settlement latency on Arc" reveal about finality?

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 0/3 claimsportfolio 0/0

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.

The agent decided no source was worth paying for this question.

Source inspection unavailable: this report has no stored excerpt ledger.

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.

Recorded purchase outcomes

Did the exact article versions bought for this answer appear in its citations? This view scores retained BUY decisions against payment observations recorded in the same dispatch trace.

Recorded settlement bookkeeping only; Circle and chain settlement have not been independently rechecked here.

This is a partial retained trace sample, not a full payment ledger. An absent matching payment does not prove that no payment occurred; excluded and unconfirmed costs remain unknown.
