sometimesplayers & private state
the server maintains the game state and returns a separate view containing the information each player is allowed to receive.
joins and reconnects
game.session.participants includes permitted names, avatar versions and active status. players(state, ctx) runs on roster changes. keep departed scores if useful, but remove private profile data when an ID disappears from ctx.players. presence leases last 90 seconds. sometimes ends games after ten minutes without player interaction or five minutes with every player minimized. joining is specific to one app instance; the host handles switching devices.
private and team views
view(state, viewer, ctx) runs separately for each joined player. team views use assignments in your private state. unjoined chat members receive a roster for the peek bar, with no game state.
randomness and scores
choose(items) uses cryptographic randomness. random(seed) creates a reproducible stream; keep secret seeds out of view. standings(players, 'highest' | 'lowest') sorts scores with shared ranks for ties. award points in server rules.
