The sources do not describe a measurement program specifically for "verifiable receipts for creator payments," and no source defines "working as intended" for that system. What can be grounded is narrower: the Keryx first-party note describes receipt-related checks and accounting states that could serve as observable indicators, while the other sources address unrelated topics (Stripe product announcements, Arc settlement latency, and idempotency keys) and do not mention creator payment receipts.
For what "working as intended" could mean, the closest supported notion is that a completed job must match the original package, creator cap, paid total and request , and that the client checks the portable receipt's canonical SHA-256 digest and binds it to the original question and returned answer . The source also cautions that a completed job means execution finished, not that the answer was adequately supported , and that payment evidence and content delivery remain separate .
For metrics or indicators, the source supports tracking whether completed jobs match the original package, creator cap, paid total and request ; whether receipt digests validate and bind to the original question and returned answer ; whether receipt snapshots are archived by digest and whether reconciliation produces a different snapshot without erasing the older one ; and whether creator amounts are correctly classified as settled, pending or unknown rather than silently turned into zero . The source also notes that the service receipt reports evidence coverage separately , and that buyers should inspect both the research result and its economics before judging the outcome .
Unanswered parts: no source provides a definition of "working as intended" for verifiable receipts for creator payments, a measurement methodology, sample sizes, error rates, or acceptance thresholds. The Stripe, Arc, and idempotency sources do not address creator payment receipts at all, so they provide no evidence for this question.

USDC onchain settlement finality is tangential background for receipt verification; only weakly supports metric selection. Cached, low cost, but low reputation (7/100). — cached bytes are free, but this read does not clear the attention gate (EV 0.25, minimum 0.45, with a required claim target).
Idempotency keys are a concrete correctness check for receipt/payment systems (no double-spend, safe retries) — a measurable 'working as intended' indicator.

The supplied passages from S1 describe the Keryx buyer client's receipt handling and reconciliation behavior, but they do not define what 'working as intended' means for verifiable receipts for creator payments, nor do they provide metrics or indicators for measuring whether such receipts are functioning as intended. S2 is only an abstract and provides no relevant measurement or definition. The question asks how to measure whether verifiable receipts for creator payments are working as intended; the sources offer only contextual details about receipt verification, creator amount settlement states, and reconciliation, without an explicit measurement framework or intended-function definition. The assessment does not establish a complete supported answer for every requested part.
Reused cached Arc Settlement Benchmarks — Measuring x402 settlement latency on Arc (free) — S3
Sub-claim "How could we measure whether verifiable receipts for creator…": 50% covered by S1 — S1 gives concrete, directly relevant measurement mechanics for a receipt-based creator-payment flow: checking the portable receipt's canonical SHA-256 digest and binding it to the original question and returned answer; matching the completed job against the original package, creator cap, paid total and request; archiving receipt snapshots by digest and reconciling divergent snapshots without erasing older ones; and treating creator amounts as settled/pending/unknown rather than silently zero. These are measurement/verification procedures, but S1 is a first-party engineering note about a buyer client, not a general framework for measuring whether verifiable receipts for creator payments work as intended, and it does not define success criteria or a measurement program.
Sub-claim "What does "working as intended" mean for verifiable receipts…": 40% covered by S1 — S1 supplies partial intent criteria: the completed job must match the original package, creator cap, paid total and request; payment evidence and content delivery remain separate; missing accounting must not be silently turned into zero; a completed job means execution finished, not that the answer was adequately supported; and buyers should inspect both the research result and its economics. It does not explicitly define 'working as intended' for verifiable receipts for creator payments, nor state acceptance thresholds or failure conditions.
Sub-claim "What metrics or indicators could be used to assess the funct…": 40% covered by S1 — S1 implies candidate indicators: receipt digest validity and binding to question/answer, package/creator-cap/paid-total/request match, snapshot reconciliation outcomes, and creator amount status (settled/pending/unknown). It does not present these as metrics, nor give rates, counts, latency, error rates, or other operational indicators. S2 is only a broad announcement abstract with no receipt or creator-payment measurement content. S3 measures x402 settlement latency on Arc, which is payment-rail timing, not verifiable receipts for creator payments.
Coverage is partial (0.4-0.5) on all three sub-claims, and the affordable skipped sources are mostly irrelevant to verifiable receipts for creator payments. The only plausibly relevant, budget-fitting item is 'Distributed Systems Notes — Idempotency keys prevent double-spends' ($0.003), which could help assess receipt correctness around duplicate debits/reconciliation, a gap S1 explicitly flags. Other skipped items concern x402 settlement timing, USDC finality, nanopayment floors, or unrelated topics and would not fill the receipt-measurement gap. Remaining budget after that purchase would be $0.010.

Final coverage assessment — The supplied passages provide partial, first-party operational detail about verifying a completed Keryx paid research job: matching the original package, creator cap, paid total and request; checking the portable receipt's canonical SHA-256 digest and binding it to the original question and returned answer; archiving receipt snapshots by digest; keeping payment evidence and content delivery separate; and not silently converting missing creator accounting into zero. This supports some measurement/verification indicators for verifiable receipts. However, the sources do not define what "working as intended" means for verifiable receipts for creator payments, do not provide a general measurement framework, and do not supply metrics such as success rate, reconciliation rate, dispute rate, creator payout accuracy, or receipt verification failure rate. S2 is only a broad abstract about Stripe announcements and does not address verifiable receipts. S3 addresses x402 settlement latency, not verifiable receipts for creator payments. S4 addresses idempotency keys and double-spend prevention, which is only tangentially related to payment correctness and not to verifiable receipts for creator payments. The assessment does not establish a complete supported answer for every requested part.
