Enum TransportFailureKind 

pub enum TransportFailureKind {
    InvalidGrant,
    Provider,
    Network,
    EndpointGuard,
}

Why an outbound OAuth call failed.

• InvalidGrant — the provider answered 400 invalid_grant: the refresh token is dead; the caller expires the account (the user must reconnect), never retries.
• Provider — the provider refused or returned an unusable shape. Zero writes; the next tick retries.
• Network — transport-level failure. Zero writes; the next tick retries.
• EndpointGuard — the guard refused (revalidation or resolution). Zero writes, zero HTTP calls.
