> ⚠ Low confidence — Each summary sentence is tied to a verbatim excerpt and model-checked; completeness and independent factual correctness remain unverified. Evidence assessment: 4 sub-claims remain below the evidence threshold. 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 is the available balance as defined in the Circle Gateway documentation?”

The Circle Gateway documentation defines the available balance as a unified USDC balance across multiple blockchains. Source text: “Circle Gateway enables a unified USDC balance across multiple blockchains.”

Evidence gap: the recorded assessment remains below the support threshold for this target.

Research target 2

Requested topic (unverified): “What is payment authorization as defined in the Circle Gateway documentation?”

Source excerpts:

  • “Deposit USDC to non-custodial Gateway Wallet contracts on any supported source blockchain, then mint USDC instantly (<500 ms) on any destination blockchain using a single API call.”

Evidence gap: the recorded assessment remains below the support threshold for this target.

Research target 3

Requested topic (unverified): “What is a recoverable job receipt as defined in the Keryx buyer recovery engineering document?”

Source excerpts:

  • “The buy command obtains a fresh quote, checks the payment policy again, writes a durable job journal, signs once and submits once.”

Research target 4

Requested topic (unverified): “How do available balance, payment authorization, and recoverable job receipt differ from each other?”

Evidence gap: no qualifying excerpt for this research target.

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.

Supplied original source status

  • https://developers.circle.com/gateway: Bounded text extracted from https://developers.circle.com/gateway; qualifying excerpts retained.

Sub-claim "What is payment authorization as defined in the Circle Gatew…": 30% covered by S2 — S2 mentions 'signature-based authorization' and 'Authorize Gateway transfers with ERC-1271 using a Circle SCA', which are related to authorization, but the passages do not define 'payment authorization' as a specific concept or describe its role in a payment flow. This is topical context without a direct definition.

Re-evaluate

Sub-claim "What is a recoverable job receipt as defined in the Keryx bu…": 70% covered by S1 — S1 passages describe a durable job journal, resume command, receipt snapshots archived by digest, and reconciliation. The term 'recoverable job receipt' is not explicitly defined, but the concept of a recoverable receipt is directly supported: the journal enables recovery after failure, and receipt snapshots are archived. Missing is an explicit definition of the term itself.

Re-evaluate

Sub-claim "How do available balance, payment authorization, and recover…": 20% covered by S1, S2 — The gathered passages do not compare these three concepts. S1 discusses payment evidence and content delivery separation, and S2 discusses balance and authorization, but there is no direct comparison of available balance, payment authorization, and recoverable job receipt. Only indirect topical context is present.

Re-evaluate

Coverage for the first, second, and fourth claims is below 0.5. The skipped source 'Keryx owner release notes — first-party validation — Keryx v0.27.44' is priced at 0.005, which fits within the remaining budget of 0.025, and its preview mentions 'docs(operator): evaluate float and obligation coverage' which may contain relevant definitions or comparisons for an operator onboarding guide. No other affordable skipped sources appear directly relevant.

Sufficiency

Final check — "How do available balance, payment authorization, and recover…": 20% assessed by S1

Sufficiency

Final coverage assessment — S1 provides Keryx-specific definitions for recoverable job receipt and related payment concepts, but does not define Circle Gateway's available balance or payment authorization. S2 provides Circle Gateway overview but lacks explicit definitions for available balance and payment authorization. S3 is unrelated. Therefore, sub-claims 1 and 2 are unanswered, sub-claim 3 is partially answered, and sub-claim 4 cannot be fully addressed. The assessment does not establish a complete supported answer for every requested part.

Synthesize

Synthesizing a grounded answer from 3 source(s)…

Evidence

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

Evidence

Delivering 1 summary sentence(s), each tied to one checked verbatim excerpt; complete synthesis remains unverified.

Evidence

Source-matched public excerpt (no creator reward) — S2, research target 1, proposed support 80% (estimate, not entailment): “Circle Gateway enables a unified USDC balance across multiple blockchains.”

Evidence

Source-matched public excerpt (no creator reward) — S2, research target 2, proposed support 40% (estimate, not entailment): “Deposit USDC to non-custodial Gateway Wallet contracts on any supported source blockchain, then mint USDC instantly (<500 ms) on any destina…”

Evidence

Source-matched reward-eligible excerpt — S1, research target 3, proposed support 50% (estimate, not entailment): “The buy command obtains a fresh quote, checks the payment policy again, writes a durable job journal, signs once and submits once.”

Evidence

Below support/reward gate — S1, research target 4, proposed support 20% (estimate, not entailment): “Payment evidence and content delivery remain separate.”

Synthesize

Prepared a sentence-cited summary from 2 source(s)

Verdict

Confidence: Low — Each summary sentence is tied to a verbatim excerpt and model-checked; completeness and independent factual correctness remain unverified. Evidence assessment: 4 sub-claims remain below the evidence threshold.

Read checkpoints

Verify locally replays supported recorded query-local reserve, release, debit and hold decisions, attribution normalization and exact micro-USDC citation/author allocations. Model proposals and eligibility are asserted inputs. Query capacity is separate from signer exposure; verification does not establish funding, reward authority or settlement.

Economic families or records marked unavailable are not verified. Missing, fractional-micro or unsafe operands are never repaired; an empty family means no captured economic decision, not complete monetary coverage.

Model proposals and selected plan actions are recorded when available. Model generation is not replayed or expected to reproduce; verification checks only deterministic checkpoints.

Micro-USDC is shown only where the existing exact converter accepts the amount. Other monetary assertions are unavailable; numeric predicate replay preserves the recorded comparison.
