MachineId class

Reads a stable, per-machine identifier provided by the operating system.

This value survives reboots and process restarts (unlike a hostname rename it is keyed to the install/hardware), making it a good stable input for a deterministic node/hub UID:

• Linux — /etc/machine-id (falling back to /var/lib/dbus/machine-id).
• macOS — the IOPlatformUUID reported by ioreg.
• Windows — MachineGuid under HKLM\SOFTWARE\Microsoft\Cryptography.

Returns an empty string when no identifier can be obtained, so UID computation degrades gracefully rather than failing. The result is always trimmed and lower-cased for stability across platforms.
