Reference
The reference describes the five resources this operator serves and the message bus their running pieces meet on. Players and Plays are the equipment and the runs on it. Remotes and Keymaps are the controllers and their button tables. MediaPreferences holds the cluster’s language defaults. The media bus is the MQTT contract that carries what happens while a run is live: reports, commands, button events, and state.
Each resource page gives the resource’s fields, then its topics and
payloads in an “On the bus” section. MediaPreferences alone has no
topics: its values resolve into a Play’s pod when the operator
creates it. The bus page gives the rules the whole topic tree
follows.
