Since v2026.8.31 (#99007 gateway-owned room authority, #99047 replica takeover, #99099 gateway-side turn driver) a room whose members all live on one gateway continues without any Desktop attached. The Bot Mode page carries the cross-machine and replication beats but never states this durability, so readers still assume the Desktop drives the room. Adds one bullet under Groups and group chats; groups.capabilities.driver flag per tui_gateway/methods_groups.py.
