Reused cached Keryx Engineering (first-party) — How Keryx pays cited creators (free) — S1

Sub-claim "What are Keryx's evidence checks before citation rewards?": 90% covered by S1 — S1 directly states the deterministic evidence ledger checks proposed evidence records (research-question index, source marker, exact quote, support score) against original gathered content, and that a citation qualifies only when its marker appears in the answer, the synthesis declares that marker, and a validated quotation has support of at least 0.4; also notes reward authorization is disabled if the final evidence-assessment transport fails. Minor gap: exact ledger validation mechanics are not fully detailed, but the requested facts are explicitly answered.

Sub-claim "How do Keryx's evidence checks relate to distributing USDC c…": 80% covered by S1 — S1 states only sources accepted by the evidence ledger enter the citation-pool allocation, the model proposes contribution weights, Keryx resolves them and allocates the citation pool in integer micro-USDC amounts, and creator payment calls use the source's authoritative payment terms. Small gap: it does not spell out every USDC-specific distribution step, but the evidence-check-to-reward relationship is directly answered.

Sub-claim "How do Keryx's evidence checks relate to paying content acce…": 70% covered by S1 — S1 separates the cost of opening source content from the reward for citing it, says the orchestrator applies budget/source/payment checks before executing a read, and notes that when no citation qualifies the citation pool stays unspent while access tolls already settled remain paid. Directly answers the relationship, though it does not detail the toll-payment mechanism itself.

Coverage is adequate across all sub-claims from the first-party Keryx engineering source. The skipped sources concern x402, USDC settlement, idempotency, disputes, and unrelated topics; none is needed to answer the requested Keryx evidence-check facts, and buying more would not be frugal.

Final coverage assessment — The supplied first-party engineering documentation directly answers the core question about Keryx evidence checks before citation rewards. It states the deterministic evidence ledger validates proposed evidence records against original gathered content, and that a citation qualifies for reward only when its source marker appears in the answer, the synthesis declares that marker, and a validated quotation has support of at least 0.4. It also explains that accepted sources enter the integer micro-USDC citation pool allocation, while access tolls are separate and already-settled tolls remain paid. The main limitation is that the source is first-party engineering documentation, not independent verification, and it does not provide implementation-level details of the checks beyond the stated conditions.

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

Verified — S1 supports claim 1 at 60%: “The deterministic evidence ledger checks these proposals against the original content that was actually gathered.”

Verified — S1 supports claim 1 at 90%: “A citation can qualify for a reward only when its source marker appears in the answer, the synthesis declares that marker, and a validated q…”

Verified — S1 supports claim 2 at 70%: “Only sources accepted by the evidence ledger enter this allocation.”

Below reward gate — S1 supports claim 2 at 20%: “Keryx resolves those weights and allocates the citation pool using integer micro-USDC amounts.”

Below reward gate — S1 supports claim 3 at 30%: “Keryx separates the cost of opening source content from the reward for citing it.”

Verified — S1 supports claim 3 at 50%: “When no citation qualifies, the citation pool stays unspent, while access tolls already settled remain paid.”
