grade evidence: hourly probes of /v1/contract-check. 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 35 products; the grade is evidence from a small sample of them.

What this grade does and doesn't measure: it scores the paid-request handshake — whether the service returns a spec-valid 402 payment challenge, how fast, and whether its price is honest. We do not pay these endpoints yet, so we do not verify that the paid response returns correct or complete content. Availability is a probe success rate measured hourly, from a single network vantage for this service.
