The main point is that a Keryx buyer client separates quoting, buying and recovering a research job, and that the buy command signs and submits only once per purchase . The first-party Keryx Engineering note states that the buy command obtains a fresh quote, checks the payment policy again, writes a durable job journal, signs once and submits once . It also warns that deleting the journal and buying again can create a second debit, so ambiguous cases may require operator reconciliation .
On the specific question of resuming a job without signing a second payment, the supplied passages do not describe a resume procedure or explicitly state that a job can be resumed without a second signature. The closest relevant material is the single-sign/single-submit behavior of the buy command and the warning about a second debit from deleting the journal and buying again , but no passage directly answers how to resume without signing a second payment. That part remains unanswered by the provided sources.

First-party Keryx engineering note whose preview directly matches the question: it explains how buyers quote, journal a purchase, and resume the original job without signing a second payment. Full text (3071 bytes) and already cached, so it is the definitive source for both the main point and Keryx Engineering's own position. Highest reputation on this subject (47/100, 48% citation rate). — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Idempotency keys make retries safe and prevent double-spends — the underlying mechanism that lets a job resume without a second payment. Cached and cheap; supports the general main point (claim 0), though it is not Keryx-specific. — the claim-aware portfolio chose a stronger, less redundant set inside the 4-source attention and $0.015000 fetch-budget caps, so this proposal stays unspent.
Explains the x402 rail where a server demands payment and an agent pays inline — context for why resuming without re-signing matters. Cached; supports claim 0 background only, not the Keryx-specific answer. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).
Benchmarks x402 batched-settlement finality on Arc; relevant to settlement mechanics behind a resumed job but not to the no-second-payment recovery question itself.

Overview of x402 end-to-end settlement timing; peripheral background for claim 0 on how payment rails finalize, but says nothing about Keryx job recovery.

Reused cached Keryx Engineering (first-party) — Recovering a Keryx paid research job (free) — S1
Sub-claim "What is the main point about resuming a Keryx job without si…": 50% covered by S1 — S1 explains the buy flow signs once and submits once, that each purchase needs a new private job directory, that a durable job journal is written before signing, and that deleting the journal and buying again can create a second debit, so ambiguous cases may require operator reconciliation. This supports the general point that recovery should rely on the durable journal rather than re-buying/re-signing, but S1 does not explicitly state a resume procedure or explicitly say a second payment signature is avoided by resuming.
Sub-claim "What does Keryx Engineering (first-party) say about resuming…": 50% covered by S1 — The first-party Keryx Engineering note (S1) describes the buyer client separating quoting, buying and recovering, the single sign/submit purchase, durable journal boundaries, and the warning that deleting the journal and buying again can create a second debit. It does not explicitly describe a resume command or state that resuming avoids signing a second payment.
Coverage is partial but the only relevant first-party source is already read. The skipped sources are unrelated to Keryx job recovery or payment-signature avoidance; none would fill the specific gap, so no purchase is recommended.
Final check — "What is the main point about resuming a Keryx job without si…": 80% assessed by S1
Final check — "What does Keryx Engineering (first-party) say about resuming…": 80% assessed by S1
Final coverage assessment — The supplied first-party Keryx Engineering note directly addresses the main point of resuming/recovering a paid Keryx job without signing a second payment: the client separates quoting, buying, and recovering; the buy command signs once and submits once; each purchase needs a new private job directory; and deleting the journal and buying again can create a second debit, so ambiguous cases may require operator reconciliation. It also explains that the client checks the portable receipt digest and binds it to the original question and answer, and that payment evidence and content delivery remain separate. The main requested point is therefore supported. The first-party source does not, however, provide a step-by-step resume procedure or explicit instruction for how to resume without signing a second payment beyond warning that deleting the journal and buying again can create a second debit and may require operator reconciliation. That is a small requested gap in the exact recovery/resume mechanics, so coverage is high but not full. The assessment does not establish a complete supported answer for every requested part.
