No challenge is sent and the RFC 9728 default path answers 404, which is consistent with a server that has no authenticated mode. This probe measures the Documentation server only; the vendor's account-scoped servers (Workers bindings, observability and the rest) were measured on 2026-09-12 in the entry's notes and are not re-run today. Same 200 and same two tools as that 2026-09-12 measurement. Nothing here measures what a tool call returns.",
