> ⚠ 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 evidence is preserved with a Keryx research receipt?”
A Keryx research receipt preserves archived receipt snapshots by digest, and later reconciliation can produce a different snapshot without erasing the older one. Source text: “Receipt snapshots are archived by digest; reconciliation may later produce a different snapshot without erasing the older one.”
The receipt keeps payment evidence and content delivery separate. Source text: “Payment evidence and content delivery remain separate.”
Research target 2
Requested topic (unverified): “Which two or three facts about that preserved evidence are most important to lead with when briefing a teammate?”
Receipt snapshots are archived by digest, and reconciliation may later produce a different snapshot without erasing the older one. Source text: “Receipt snapshots are archived by digest; reconciliation may later produce a different snapshot without erasing the older one.”
Payment evidence and content delivery remain separate. Source text: “Payment evidence and content delivery remain separate.”
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.

Official Keryx release notes mention inspecting recorded evidence, potentially relevant to what evidence is preserved with a research receipt. — the claim-aware portfolio chose a stronger, less redundant set inside the 4-source attention and $0.025000 fetch-budget caps, so this proposal stays unspent.

Reused cached Keryx Engineering (first-party) — Recovering a Keryx paid research job (free) — S2
Sub-claim "What evidence is preserved with a Keryx research receipt?": 80% covered by S2 — S2 directly states that receipt snapshots are archived by digest, payment evidence and content delivery remain separate, and a retained success response with a Circle reference is labeled seller-reported settlement. It also notes creator amounts can be settled, pending, or unknown. However, the exact set of evidence items preserved with a receipt is not exhaustively enumerated; the passages focus on separation and labeling rather than a complete inventory.
Sub-claim "Which two or three facts about that preserved evidence are m…": 60% covered by S2 — S2 provides several important facts: receipt snapshots are archived by digest; payment evidence and content delivery are separate; a retained success response with a Circle reference is labeled seller-reported settlement; creator amounts can be settled, pending, or unknown. These are directly relevant and could form the basis of a briefing. However, the source does not explicitly rank or select the two or three most important facts, so the prioritization is inferred rather than directly answered.
Coverage for both sub-claims is adequate (0.8 and 0.6). The first-party source S2 directly addresses the preserved evidence and provides key facts that can be used to lead a briefing. No skipped sources are specifically relevant to Keryx research receipts; the skipped sources are general or unrelated. The remaining budget is not needed for additional purchases.
Final check — "What evidence is preserved with a Keryx research receipt?": 90% assessed by S2
Final check — "Which two or three facts about that preserved evidence are m…": 80% assessed by S2
Final coverage assessment — The question asks what evidence is preserved with a Keryx research receipt and which two or three facts to lead with. S2 (Keryx Engineering first-party) directly addresses receipt evidence: receipt snapshots are archived by digest, payment evidence and content delivery remain separate, and a retained success response with a Circle reference is labeled seller-reported settlement. It also notes creator amounts can be settled, pending, or unknown, and the service receipt reports evidence coverage separately. S1 provides a brief illustrative note that source provenance and payment status are separate and to inspect the receipt for settled, pending or simulated payments, but it is marked as illustrative demo content, not factual research evidence. The most important facts to lead with are: (1) receipt snapshots are archived by digest and older snapshots are not erased; (2) payment evidence and content delivery are separate, with a retained success response labeled seller-reported settlement; (3) the receipt reports evidence coverage separately, and completed job does not mean adequately supported. Coverage for sub-claim 1 is high because S2 explicitly describes what is preserved. Coverage for sub-claim 2 is also high because S2 provides the key facts to lead with, though the selection of exactly two or three facts is an inference from the material.

One deterministic JSON bundle binds the answer, visible decisions, exact article versions, claim evidence and a Circle-settlement snapshot under SHA-256. Retain the digest to detect later changes; the self-check is not a publisher or Keryx signature.
Recorded purchase outcomes
Did the exact article versions bought for this answer appear in its citations? This view scores retained BUY decisions against payment observations recorded in the same dispatch trace.
Recorded settlement bookkeeping only; Circle and chain settlement have not been independently rechecked here.
This is a partial retained trace sample, not a full payment ledger. An absent matching payment does not prove that no payment occurred; excluded and unconfirmed costs remain unknown.
