Keryx Engineering (first-party) establishes that the buyer client separates quoting, buying and recovering a research job , and 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 establishes that each purchase needs a new private job directory , and that deleting the journal and buying again can create a second debit, so ambiguous cases may require operator reconciliation .
What remains uncertain is that payment can remain unconfirmed even when a job exists without a retained success response , and that creator amounts can be settled, pending or unknown, with the client required not to silently turn missing accounting into zero . The first-party note does not explicitly state a guarantee that resuming a job avoids a second payment; it only warns that deleting the journal and buying again can create a second debit and that ambiguous cases may require operator reconciliation .

Sub-claim "What does Keryx Engineering (first-party) establish about re…": 30% covered by S1, S2 — S1 establishes adjacent facts: the buy command signs once and submits once, each purchase needs a new private job directory, a durable job journal is written before signing, and deleting the journal and buying again can create a second debit. S2 states that importing a file saves a local recovery copy and does not send a new payment, and that a minimal account/job marker remains to prevent another submission. However, neither passage explicitly describes a procedure for resuming an existing Keryx job without signing a second payment; the closest support is the recovery-copy/no-new-payment statement and the anti-resubmission marker, which are topical context rather than a direct answer.
Sub-claim "What remains uncertain about resuming a Keryx job without si…": 40% covered by S1, S2 — S1 identifies uncertainty around ambiguous cases requiring operator reconciliation, possible second debits from deleting the journal and buying again, unconfirmed payment without a retained success response, and creator amounts that may be settled, pending, or unknown. S2 notes that deletion does not cancel a signed or in-flight payment, refund funds, delete the server result, or remove exports/backups/disk remnants/other-tab copies, and that local data may be accessible to anyone controlling the browser profile or scripts. These are partial uncertainty statements about recovery and payment status, but they do not explicitly frame what remains uncertain specifically about resuming a job without signing a second payment.
Coverage is partial but the skipped sources are unrelated to Keryx job recovery or payment resumption (they concern agents, Cloudflare Workers, music, NASA engineering, unrelated Keryx projects, stablecoins, x402, idempotency, gardening, retro hardware, fraud, Ethereum agents, crypto news, etc.). No affordable skipped source specifically addresses resuming a Keryx job without a second payment, so buying more is not justified.
Final check — "What does Keryx Engineering (first-party) establish about re…": 50% assessed by S1
Final check — "What remains uncertain about resuming a Keryx job without si…": 40% assessed by S1
Final coverage assessment — S1 (Keryx Engineering first-party) directly addresses the recovery/resume scenario: it establishes that deleting the journal and buying again can create a second debit, that ambiguous cases may require operator reconciliation, and that a retained success response is only seller-reported settlement (not independent Circle/on-chain proof), so payment can remain unconfirmed even when a job exists. It does not, however, explicitly state a procedure for resuming a job without signing a second payment, nor does it enumerate what remains uncertain in a dedicated way. S2 is a privacy policy and does not address resuming a job without a second payment. The assessment does not establish a complete supported answer for every requested part.
Synthesizing a grounded answer from 2 source(s)…
Relevance review returned; only checked excerpts can retain support, and review cannot raise it.
Below support/reward gate — S1 supports claim 1 at 10%: “The independent Keryx buyer client separates quoting, buying and recovering a research job.”
Verified — S1 supports claim 1 at 40%: “The buy command obtains a fresh quote, checks the payment policy again, writes a durable job journal, signs once and submits once.”
Verified — S1 supports claim 2 at 40%: “Without that response, payment can remain unconfirmed even when a job exists.”
Below support/reward gate — S1 supports claim 2 at 10%: “Creator amounts can also be settled, pending or unknown; the client must not silently turn missing accounting into zero.”
