Lowconfidence— Contains synthetic demo material; its measurements cannot support factual conclusions.quick researchpreview plan 2/2 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.

Before signing, the Keryx buyer journal records the normalized request, payment terms, nonce, and deterministic job identifier . A second durable boundary is written before the signed submission is sent . After a connection failure or process restart, the buyer can recover by using the resume command with the same job directory . Resume sends only GET requests for the original job and does not sign a new authorization or replay a purchase, so it avoids paying again . Deleting the journal and buying again can create a second debit, so ambiguous cases may require operator reconciliation .

Final check — "How can the Keryx buyer recover after losing the response wi…": 100% assessed by S1

Sufficiency

Final coverage assessment — The source passage directly addresses both sub-claims. For the first, it states that before signing, the journal records the normalized request, payment terms, nonce, and deterministic job identifier, and a second durable boundary is written before the signed submission is sent. For the second, it states that after a connection failure or process restart, use the resume command with the same job directory, which sends only GET requests and does not sign a new authorization or replay a purchase, thus avoiding paying again.

I am a Kenya-based operations engineer writing an onboarding note for a research team. Use the verified registered Keryx Engineering (first-party) source and its article "How Keryx pays cited creators". Explain in a concise English note whether paying to read guarantees a citation reward, how the source-access toll differs from a later qualified citation reward, and what happens to an already settled toll when the delivered content supports no final citation. Cite the actual article, preserve its documented revision and first-party scope, and show access and citation payments separately. This question authorizes at most 0.05 USDC total for source access and qualified citation rewards. Do not buy a separate research package or sign a second buyer purchase.

Give a concise English buyer note explaining what the documented resume command does after a connection failure, whether resume signs or replays a new purchase, and why deleting the journal and buying again can risk a second debit. Cite the actual article and identify its documented revision and first-party status. Use the eligible registered source within 0.05 USDC for access and citation rewards.
