Arena
A room you open yourself: participants ask to come up on stage, and the host — which is you — decides who goes up and who comes down.
Opening your own
Arena is the format nobody schedules for you. When you open a room you declare its intent, how many stage seats there are, how long it lasts and — most importantly — who can watch.
There are three visibilities: public, social and private. The choice is yours at the moment you open it, and it defines the room's reach.
What the host can and cannot do
The host has exactly three actions over the queue: bring someone who is waiting up on stage, take someone off the stage, and open the profile of someone in the queue. That is the whole list.
Operating controls — cutting the scene, muting, emergency stop, moderation — do not belong to the host. They belong to the production panel, and that separation is enforced in the code, not entrusted to the memory of whoever builds the screen.
The queue
Whoever is in the queue appears to the host by a stable identifier and by position, with no name, age, city or compatibility — that data simply does not come with the queue reading.
Afterwards
An Arena may have a replay, and access to the replay is controlled: the room having existed does not mean the recording stays open.
