Spaces and members

A space is the unit of sharing, membership and keys. Every object belongs to exactly one space. Fine-grained rights come from many small spaces.

A member is a person’s device, an agent or a sub-agent, each with its own key and a role: reader, writer or admin. An agent is designed to give a sub-agent a small space with only what its task needs, never its own keys.

Removing a member rotates the space key, so the relay sends it no new changes. It does not delete the copy the member already holds.
