+- After a successful Discord smoke/roundtrip, shut down the guest VM before handoff (`prlctl stop "$VM_NAME"` or the concrete VM name). The macOS smoke harness should do this automatically after successful Discord proof; still stop the VM manually after ad-hoc Discord checks. Do not leave the Discord-configured guest running; it can keep reading/posting in `#maintainer` and spam Discord after the proof is complete.
 - Keep the Discord token only in a host env var.
 - Use installed `openclaw message send/read`, not `node openclaw.mjs message ...`.
 - Set `channels.discord.guilds` as one JSON object, not dotted config paths with snowflakes.

 - Avoid `prlctl enter` / expect for long Discord setup scripts; it line-wraps/corrupts long commands. Use `prlctl exec --current-user /bin/sh -lc ...` for the Discord config phase.
 - Full 3-OS sweeps: the shared build lock is safe in parallel, but snapshot restore is still a Parallels bottleneck. Prefer serialized Windows/Linux restore-heavy reruns if the host is already under load.
 - Harness cleanup deletes the temporary Discord smoke messages at exit.
