    // Required methods
    fn check(
        &self,
        route: &RouteSpec,
        mutation: &DocumentMutation,
    ) -> Result<(), String>;
    fn retained_bytes(&self) -> Option<usize>;
}

Host-local original contributor custody a document change carries to the transport, never serialized on the wire. The toolkit’s invocation scope mints it (ui::invocation_scope::DocumentAuthorization); the transport checks it against the change it is about to sign.

Required Methods

fn check( &self, route: &RouteSpec, mutation: &DocumentMutation, ) -> Result<(), String>

Whether the change’s body and its current contributors are bound to route.

fn retained_bytes(&self) -> Option<usize>

The bytes the custody holds while its change waits in the transport’s queue, counted against the queue’s budget; None when they overflow.
