Reused cached Keryx Engineering (first-party) — Recovering a Keryx paid research job (free) — S1

Reused cached Stablecoin Ledger — Why USDC settles instantly onchain (free) — S2

Sub-claim "What does the phrase "Recovering a Keryx paid research job" …": 90% covered by S1 — S1 is the first-party note titled 'Recovering a Keryx paid research job' and describes the buyer client's separation of quoting, buying and recovering a research job, including durable job journal, receipt digest binding, and reconciliation. It directly identifies the phrase as a Keryx engineering note about recovering a paid research job. Minor gap: it does not fully define 'recovering' as a standalone procedure beyond the surrounding buy/journal/receipt context.

Sub-claim "What does "Recovering a Keryx paid research job" reveal abou…": 0% covered — S1 never mentions USDC; it discusses Keryx treasury payee, payment policy, job journal, receipts, and reconciliation but no USDC. S2 discusses USDC generally but is unrelated to the Keryx recovery note. No supplied passage connects the Keryx recovery article to USDC.

Sub-claim "What is USDC in the context of Keryx paid research jobs?": 10% covered by S2 — S2 defines USDC as a fully-reserved dollar stablecoin with instant onchain settlement useful for machine-to-machine agent payments, which is topical context. However, it does not state that Keryx paid research jobs use USDC, nor describe USDC's role in Keryx payments. S1 mentions a 'Keryx treasury payee' and payment terms but does not name USDC.

Coverage is adequate for the phrase's referent (S1), but the USDC-specific sub-claims are essentially uncovered. No skipped source directly addresses USDC in the context of Keryx paid research jobs; the closest USDC-related skipped item (Circle/Tazapay) concerns cross-border payments, not Keryx. Given the remaining budget of 0.02 and lack of a clearly relevant affordable source, buying more is not recommended.

Final check — "What does the phrase "Recovering a Keryx paid research job" …": 90% assessed by S1

Final check — "What does "Recovering a Keryx paid research job" reveal abou…": 0% assessed

Final check — "What is USDC in the context of Keryx paid research jobs?": 20% assessed by S2

Final coverage assessment — The first-party Keryx note (S1) describes the buyer client's quoting, buying, and recovery process for a paid research job, but never mentions USDC. The Stablecoin Ledger abstract (S2) explains what USDC is generally, but does not connect USDC to Keryx or to the recovery article. Therefore the central question—what the article reveals about USDC—is not answered; only general USDC context is provided. The assessment does not establish a complete supported answer for every requested part.
