Authorization is evaluated before the HTTP method: the same vendor's Index MCP answers a GET 405 and names its own transport in the refusal, while this one reveals nothing. Recorded so a link checker or an agent meeting this surface reads the 401 as a live gated endpoint. The www-authenticate challenge is REDACTED in this record's headers: the registry's credential filter refuses its shape, although a `Bearer` challenge naming a public document carries no credential. It is printed verbatim in appendix (M).",
