grade evidence: hourly probes of /arbitrum/new-pools. Availability, latency and protocol measure the operator's shared infrastructure and generalize across its products; the price check applies to the probed product. We are beginning to probe secondary products, rotating one per hour. This operator lists 68 products; the grade is evidence from a small sample of them.

Availability is a probe success rate measured hourly, from a single network vantage for this service.
