POST /v1/auth/register,
POST /v1/auth/login, or the browser OAuth flow.
The CLI’s
naive verify command still exists, and it is a refusal: it makes no
request, reaches no endpoint, and prints the two commands that do work
(naive auth email <email>, naive auth google). It is retired rather than
deprecated — the flow was removed for security and has no successor, so upgrading
the CLI will not bring it back.
