> This is a method of the [**DeliveryPreflightProtocol**](../classes/DeliveryPreflightProtocol) class in the [**protocols**](../modules/protocols) module.

Pre-flight `target` against the live channel/route registry.

Called at *creation* time (when a scheduled/agent-initiated send is
registered) so an unroutable target is rejected or warned on with an
actionable message, instead of being silently dropped when the job
fires.

  class:`DeliveryValidation` (`ok` / `reason` / `hint` /
  `preview`).
