app.cosmosis.cluster

A personally curated group of accounts. Clusters have no fixed size cap: membership is stored as separate `app.cosmosis.clusterMember` records rather than inline, so a Cluster can hold thousands of members. Clusters are always permissioned: each Cluster lives inside its own dedicated Space of type `app.cosmosis.clusterSpace`. Note that the Space's own member list governs *access* to the Cluster and is distinct from the clusterMember records, which are the Cluster's *contents*.
