The atproto permissioned space proposal is out. Seems to be more or less as described in earlier blog posts. It's an ACL system where each space has a central gatekeeper that maintains the list of who has read privilege. Spaces are partitioned amongst many repos but all repos have to be queried to get the complete history so it's unlike distributed version control in that no one has a full copy of the data. If I were a prospective user of this I'd be concerned with confused deputy vulnerabilities and repo availability.
