What problem led to verifiable receipts for creator payments, and what changed from earlier approaches?

The provided sources do not describe what problem specifically led to verifiable receipts for creator payments, nor do they describe what changed from earlier approaches to creator payments. The Keryx engineering note describes a buyer client that separates quoting, buying, and recovering a research job, and it mentions that the client checks a portable receipt's canonical SHA-256 digest and binds it to the original question and returned answer, but it does not state the motivating problem for verifiable receipts or contrast them with earlier approaches. The other sources concern x402 as an HTTP payment rail, x402 settlement latency on Arc, and a crypto market rally; none addresses verifiable receipts for creator payments. Therefore both research questions remain unanswered by the supplied passages.

Free-preview pre-check maps an actionable source to every sub-claim (2/2); paid reading may proceed within the budget.
Keryx Engineering's first-party notes on quoting, journaling purchases, and resuming jobs without a second payment directly address the problem of proving/verifying a paid research job — the core of verifiable receipts (claims 0 and 1). Highest reputation (45/100) and full text cached. — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Agent Economy Weekly's x402 rail piece explains how servers demand payment and agents pay inline — directly relevant to the mechanism shift behind verifiable creator-payment receipts (claim 1). Decent reputation (23/100, 12 citations) and already cached, so reuse is free. — selected for the claim-aware evidence portfolio (targets claim 2; 0 fetch USDC, 1 attention slot).
Arc Settlement Benchmarks measures x402 batched-settlement finality — directly informs what changed in payment settlement approaches (claim 1). Cached and moderately cited (10 citations). — selected for the claim-aware evidence portfolio (targets claim 2; 0 fetch USDC, 1 attention slot).
Stablecoin Ledger's abstract is about USDC settlement finality on L2s, not about why verifiable receipts emerged for creator payments or what changed from earlier approaches. Low reputation (8/100) and no direct link to either subClaim.
Onchain Micropayments Digest covers batched settlement lowering the payment floor — relevant to what changed in earlier vs. new creator payment approaches (claim 1). High avg weight (0.88) and cached. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).

Sub-claim "What problem led to verifiable receipts for creator payments…": 20% covered by S1 — S1 describes the buyer client's receipt verification and reconciliation mechanics (canonical SHA-256 digest, binding to question/answer, archived snapshots, separate payment evidence and content delivery), which is topical context for why receipts exist, but it never states the originating problem (e.g., unverifiable or ambiguous creator payment accounting) that motivated verifiable receipts. No explicit problem statement is supplied.
Sub-claim "What changed from earlier approaches to creator payments wit…": 10% covered by S1 — S1 contrasts some current behaviors (durable job journal, single sign/submit, receipt digest binding, no silent zeroing of missing creator accounting, no automatic refund of unused reserve) but does not describe any earlier approach to creator payments or what specifically changed relative to it. Only current-state mechanics are provided, not a before/after comparison.
Both sub-claims are below 0.5. S1 gives only current receipt mechanics, not the motivating problem or the prior-approach contrast. Among affordable skipped sources (budget 0.015), the CoinDesk item on paying creators in stablecoins is the only one plausibly touching creator payment models and could partially fill the gap; the x402 finalization item (0.002) is about settlement timing, not creator-payment receipt provenance, and the idempotency/double-spend note (0.003) addresses retry safety rather than the requested problem or change. Recommend only the creator-payments item to stay frugal.

Final check — "What problem led to verifiable receipts for creator payments…": 0% assessed
Final check — "What changed from earlier approaches to creator payments wit…": 0% assessed
Final coverage assessment — The supplied passages do not describe the problem that motivated verifiable receipts for creator payments, nor what changed from earlier approaches. S1 describes a buyer client's receipt verification, journaling, and reconciliation mechanics, but never states the prior problem or the earlier approach it replaced. S2 and S3 concern x402 payment rails and settlement latency, unrelated to creator payment receipts. S4 is a general crypto market abstract with no relevant detail. The assessment does not establish a complete supported answer for every requested part.
