The socket background sessions connect through is now created per start rather than shared.
What's wrong with this entry?
The socket that background sessions connect through, including its authentication handshake, 30-second heartbeat, attacher caps, startup watchdog and prompt-draft restore, moved from module-level state into an object created per start, and its job-state reads and writes now take a storage backend. Behaviour, including the accounting of unauthenticated drops, is unchanged.
