Between the people in them
A direct message belongs to the people in it — full stop. It isn’t a channel and doesn’t behave like one:- It’s not part of the space’s memory. What you say in a DM stays out of what the space agent knows and answers from. The agent remembers the space’s rooms, not its hallway conversations — and that’s true for a group DM just as for two people.
- It’s scoped to the space. Your DMs live inside the space you share with those people — the conversation and its context stay where the working relationship is.
