Item 7 of the spec wants game-state and membership-state changes to land as durable inbox entries the affected players can re-read after the fact — push alone times out of the 5-minute ring buffer. Stage B adds the admin-kind send matrix (owner-driven via /user, site-admin driven via /admin) plus the lobby lifecycle hooks: paused / cancelled emit a broadcast system mail to active members, kick / ban emit a single-recipient system mail to the affected user (which they keep read access to even after the membership row is revoked, per item 8). Migration relaxes diplomail_messages_kind_sender_chk so an owner sending kind=admin keeps sender_kind=player; the new LifecyclePublisher dep on lobby.Service is wired through a thin adapter in cmd/backend/main, mirroring how lobby's notification publisher is plumbed today.
