The Adapter's end of the socket to the Agent.

Fire and forget, deliberately. If the Agent is not listening the Event is dropped rather than queued or retried. Two reasons: this often runs inside a process that is already dying, and the Agent being down is itself something the next boot reports — a queue here would trade a known gap for an unknown one, in the process least able to afford the memory.

Reconnection is lazy. A send on a dead socket tries once to reconnect and then gives up until the next send, so a missing Agent costs one failed connect per Event rather than a busy loop.
