Start with a real commerce workflow
The test used CommerceAgentBench task api-amazon-margin-floor-audit. One execution performs 40 HTTP operations: reading listings, probing marketplaces, previewing and applying qualified price updates, creating and submitting a feed, polling its result, and generating a settlement report.
The workflow was executed 25,000 times with a unique identity and hash-linked receipt chain for every run. Expected 404 probes remained visible as honest receipts; they were not hidden as failures.
Can one million commerce receipts cross the external NEO rail—and still be independently proven afterward?
One continuous evidence path
40 receipts close into one meaningful workflow commitment.
25,000 Ed25519-signed envelopes enter a dedicated external boundary.
Exact commitments become durable append-only frames.
Gap-free delivery forms verifiable roots.
The measured proof horizon is closed.
62 folds are confirmed at positions 90,006,547–90,006,608.
Reconstructed, not merely reported
A separate fail-closed verifier replayed the million source receipts, verified every signature and batch link, re-read the append-only journal, checked the gap-free NEOCL span, verified the endpoint Merkle proofs and confirmed final NEOva2 readback. Every required check returned PASS.
