Enum NotificationFailureKind 

pub enum NotificationFailureKind {
    InvalidRequest,
    Authentication,
    AuthorityRevoked,
    Unsupported,
    Capacity,
    Backpressure,
    Protocol,
    SourceUnavailable,
    Transport,
    Timeout,
    ServerDraining,
    Cancelled,
    SequenceExhausted,
}

A closed failure category shared by language bindings and delivery adapters.

Adapters retain the original cause separately. A category does not grant retry authority: authentication, protocol and backpressure failures are terminal by default, and transport retries require the caller’s remaining reconnect budget.
