Sub-claim "What does 'Recovering a Keryx paid research job' mean in Ker…": 80% covered by S1 — S1 directly explains the buyer client separates quoting, buying, and recovering a research job; recovery uses a resume command with the same job directory after connection failure or restart, sending only GET requests for the original job without signing a new authorization or replaying a purchase. It also notes job identifiers are sensitive bearer access and ambiguous cases may require operator reconciliation. This is a direct answer, though the excerpt does not detail the full recovery procedure end-to-end.

Sub-claim "How is USDC involved in the recovery of paid research jobs?": 0% covered — S1 never mentions USDC; it refers to a trusted Keryx treasury payee, all-in price ceiling, service fee, creator budget, and funded wallet but does not identify the asset or rail. S2 discusses USDC generally but not Keryx recovery. No supplied passage connects USDC to Keryx paid research job recovery.

Sub-claim "What does this process reveal about USDC's use or characteri…": 10% covered by S2 — S2 provides general USDC characteristics (fully-reserved dollar stablecoin, peer-to-peer onchain settlement in seconds, final and programmable, suited to machine-to-machine commerce), but it is not tied to the Keryx recovery process. It offers topical context about USDC without answering what the Keryx recovery process reveals about USDC.

Coverage is weak for the two USDC-specific sub-claims. S1 answers what Keryx recovery means but never mentions USDC, and S2 only gives generic USDC properties unrelated to Keryx. The skipped sources are mostly irrelevant (gardening, retro consoles, Bitcoin commentary, etc.). Within the $0.02 budget, the most relevant affordable gaps are the x402 agent payment rail source ($0.004), which could clarify the payment rail/asset context for agent jobs, and the idempotency keys source ($0.003), which could clarify retry/double-debit behavior relevant to recovery. Other skipped sources do not address Keryx recovery or USDC's role in it.

Final coverage assessment — S1 explicitly describes the recovery process of a paid research job in Keryx's system, covering what it means and how it works, but does not mention USDC. S2 provides characteristics of USDC but is not connected to the recovery process in Keryx. There is no source that links USDC to the recovery process or derives insights about USDC from it. Therefore, sub-claims 2 and 3 are not supported, with coverage of 0.0, and all requested parts for those claims are missing. The assessment does not establish a complete supported answer for every requested part.

Synthesizing a grounded answer from 4 source(s)…

Relevance review returned; only checked excerpts can retain support, and review cannot raise it.

Below reward gate — S1 supports claim 1 at 20%: “The independent Keryx buyer client separates quoting, buying and recovering a research job.”

Verified — S1 supports claim 1 at 80%: “After a connection failure or process restart, use the resume command with the same job directory.”
