> We already have an event corresponding to the successful distribution of a package [0].
> In the Distribution Core impl, this event is (correctly) generated when the package is successfully distributed [1]. However, if the distribution agent has a valid error-strategy associated with it and if the attempts to distribute them exceed a fixed number of retries, the packages are moved _silently_ to error-queue [2].
> I propose that this asymmetry be addressed.
> Since {{DistributionEventTopics}} is a {{ProviderType}}, it should be possible to introduce another constant (which queue-processors in Distribution Core, as well as any custom ones) can use to identify failed distribution-requests [3].
> Distribution Core can be further enhanced to create this event when it re-enqueues the queue-item that has exceeded its retries in the error-queue [4].
