How Namescope checks it
Availability comes from RDAP, the registry's own protocol, not from a reseller's search box. When a registry publishes no RDAP endpoint the report says so and links to the manual lookup instead of guessing.
RDAP lookups on the extensions that matter for the plan, with the registry response quoted in the report.
