A ships a complete invite product surface (mint RPC, /join redemption into grants, RoomAudit, multi-cap grants, CLI, timeline system rows, and an end-to-end invites.bb suite) that becomes real private-room UX. B’s lasting pieces are GitHub OAuth/session/pseudonym gating and projecting identity events, but a large fraction of the patch is relocating the in-tree durable crate (mass deletion + git dep) rather than new in-project capability.
