§ IIThe reading1 cited

> ⚠ Low confidence — Each summary sentence is tied to a verbatim excerpt and model-checked; completeness and independent factual correctness remain unverified. Evidence assessment: 1 evidence-verified source cover every sub-claim, but corroboration or support strength is limited. Treat this as provisional.

Model-written summary with sentence-level citations. Each sentence is followed by the verbatim source text it was checked against; sentences without a qualifying excerpt were removed.

Research target 1

Requested topic (unverified): “What specific claim does Keryx Engineering make about why a source marker alone cannot support a claim?”

Keryx states that a source marker alone cannot support a claim because a citation qualifies for a reward only when the marker appears in the answer, the synthesis declares that marker, and a validated quotation has support of at least 0.4. Source text: “A citation can qualify for a 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.”

Research target 2

Requested topic (unverified): “What evidence or reasoning does Keryx Engineering provide to support that claim?”

Keryx supports this by saying the deterministic evidence ledger checks proposed evidence records against the original content that was actually gathered. Source text: “The deterministic evidence ledger checks these proposals against the original content that was actually gathered.”

Summary sentences are model-written and model-checked, not independently verified; they claim no more than their excerpts and are not a complete synthesis. Excerpts establish source grounding, not that a source is correct. Source statements may be wrong or conflicting. Payment states remain in the separate receipt.

Re-evaluate

Sub-claim "What specific claim does Keryx Engineering make about why a …": 90% covered by S1 — S1 states that a citation can qualify for a 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. This implies that a source marker alone is insufficient; it must be accompanied by a validated quotation with sufficient support. The exact wording 'source marker alone cannot support a claim' is not present, but the conditions clearly indicate that a marker by itself does not qualify. The claim is directly answered with a small gap: the source does not explicitly say 'cannot support a claim' but rather lists additional requirements.

Re-evaluate

Sub-claim "What evidence or reasoning does Keryx Engineering provide to…": 70% covered by S1 — S1 provides reasoning: the deterministic evidence ledger checks proposed quotations against original content, requiring exact quotes between 8 and 240 characters and support of at least 0.4. This explains why a marker alone is insufficient—the system validates quotations. However, the passage does not explicitly connect this validation process to the phrase 'source marker alone cannot support a claim'; the reasoning is implicit. The evidence is directly relevant but lacks an explicit statement linking the two.

Re-evaluate

Coverage for both sub-claims is adequate (0.9 and 0.7). The first-party source S1 directly addresses the conditions for a citation to qualify, which implies that a source marker alone is insufficient. The reasoning is supported by the description of the evidence ledger's validation process. No additional sources are needed; the remaining budget is minimal and the skipped sources are not relevant to this specific first-party claim.

Sufficiency

Final check — "What specific claim does Keryx Engineering make about why a …": 100% assessed by S1

Sufficiency

Final check — "What evidence or reasoning does Keryx Engineering provide to…": 100% assessed by S1

Sufficiency

Final coverage assessment — The first-party Keryx documentation (S1) explicitly states that a citation can qualify for a 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. This directly answers why a source marker alone cannot support a claim: the marker is necessary but not sufficient; a validated quotation with adequate support is also required. The same passage provides the supporting reasoning: the deterministic evidence ledger checks proposed quotations against the original content, requiring an exact quote (8-240 characters) and a support score of at least 0.4. S2 and S3 do not address this specific claim.
