A public square is not only a place where people speak. It is also a routing system. A post may exist without becoming eligible for recommendation. It may become eligible without entering a candidate set. It may enter a candidate set without being placed. It may be placed without rendering. It may render without being noticed. It may be noticed without being understood. A later event may follow without having been caused by any of it. This sequence is ordinary enough to be invisible. It is also where a serious defensive question begins.

A UVLM research manuscript examines whether real high-consequence information could be conveyed through public media that only a prepared audience can interpret, and how to detect such channels without turning art, spirituality, or coincidence into accusation.
