 ## Notes
 
-- Only commands emitting `GameEvent`s appear in `PlayerEventHandler`
+- Game commands are handled by `Server_Player`, `Server_AbstractParticipant`, or `Server_Game`, depending on the command.
-- Some commands affect game state without direct client events
+- Only commands that emit `GameEvent`s produce corresponding `PlayerEventHandler` callbacks.
-- Judge commands are transport-level wrappers, not gameplay primitives
+- Some commands modify server state without generating a dedicated client event.
+- Judge commands are transport wrappers that execute other game commands on behalf of another player.
