After reading Keryx Engineering (first-party) on journaling a Keryx paid job before submission, what follow-up question would help test the claim?

> ⚠ Low confidence — 1 sub-claim remains below the evidence threshold within budget. Treat this as provisional.
Keryx Engineering states that the buy command obtains a fresh quote, checks the payment policy again, writes a durable job journal, signs once and submits once . Each purchase needs a new private job directory . Before signing, the journal records the normalized request, payment terms, nonce and deterministic job identifier . A second durable boundary is written before the signed submission is sent . Private keys and payment signatures are not written into the journal . The job identifier itself is sensitive because it provides bearer access to the research result . Deleting the journal and buying again can create a second debit, so ambiguous cases may require operator reconciliation .
A follow-up question that would help test the claim is: what specific implementation or usage details are documented at the referenced revision (e.g., in the buyer-agent documentation or research-package code) that would confirm or contradict the described journaling behavior before submission?

Free-preview pre-check maps an actionable source to every sub-claim (2/2); paid reading may proceed within the budget.
First-party Keryx engineering note on exactly the topic: how buyers quote, journal a purchase and resume the original job without a second payment. Full text (3071 bytes) and already cached, so it directly answers claim 0 and supplies the basis for the follow-up test question in claim 1. Highest reputation on this subject (43/100, cited 14/32 runs). — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Arc x402 settlement latency benchmarks could help test whether a journaled Keryx job actually settles/resumes as claimed, giving a measurable follow-up angle for claim 1. Cached abstract only (340 bytes), so value is moderate. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).
Overview of x402 end-to-end finalization timing is a plausible cross-check for the follow-up question about whether a journaled paid job resumes without a second payment. Cached abstract, narrow scope. — cached bytes are free, but this read does not clear the attention gate (EV 0.35, minimum 0.45, with a required claim target).
Explains x402 as an agent payment rail, useful background for framing a test of the journaling claim, but it does not address journaling or buyer recovery specifically. Cached abstract. — cached bytes are free, but this read does not clear the attention gate (EV 0.30, minimum 0.45, with a required claim target).

Reused cached Keryx Engineering (first-party) — Recovering a Keryx paid research job (free) — S1
Sub-claim "What does Keryx Engineering state about journaling a Keryx p…": 100% covered by S1 — S1 directly states that the buy command writes a durable job journal before signing/submitting, that each purchase needs a new private job directory, that before signing the journal records the normalized request, payment terms, nonce and deterministic job identifier, that a second durable boundary is written before the signed submission is sent, and that private keys and payment signatures are not written into the journal.
Sub-claim "What follow-up question would help test the claim about jour…": 70% covered by S1 — S1 supplies the substantive claim details needed to formulate a follow-up test question (journal contents, timing before signing/submission, second durable boundary, exclusion of private keys/signatures, and the warning that deleting the journal and buying again can create a second debit). It does not itself pose a follow-up question, so the requested question must be constructed from the provided claim, leaving a small gap.
Coverage is adequate: the first-party Keryx Engineering source directly answers what is stated about journaling before submission, and its details are sufficient to formulate a follow-up test question. The skipped sources concern x402 settlement, idempotency, and unrelated topics; none is needed to fill a material gap, and buying more would not be frugal.
Final check — "What does Keryx Engineering state about journaling a Keryx p…": 100% assessed by S1
Final check — "What follow-up question would help test the claim about jour…": 0% assessed
Final coverage assessment — The supplied Keryx Engineering passages directly answer the first sub-claim: they state that the buy command writes a durable job journal before signing and before the signed submission is sent, with specified journal contents and exclusions. The second sub-claim asks for a follow-up question to test that claim; the source does not itself provide or imply such a follow-up question, so that requested part remains missing. The assessment does not establish a complete supported answer for every requested part.
