Background

The ephemeral server spawning polls $manager in the parent process after spawning a child, which never succeeds (the child sets $manager in its own address space). The --attach mode has no actual server discovery mechanism.

Demonstrable Outcome

Server discovery uses DRb over a Unix socket. The running Aethyr server exports $manager via DRb, and experiments connects to it reliably in both attach and spawn modes.

Acceptance Criteria

Aethyr server exports $manager via DRb.start_service('drbunix:tmp/aethyr.drb', $manager)
Experiments Runner connects via DRbObject.new_with_uri in attach mode
Spawn mode forks, waits for DRb socket, then connects
bin/aethyr_experiments has execute permission (755)
Unit tests verify both connection modes
