      3 // Reads the first virtual-device definition from the manifest the Hydra daemon writes at
      4 // /Library/Application Support/hydra/devices.json (world-readable; coreaudiod runs as
      5 // _coreaudiod and can't read the user's home dir). Lets the device be renamed without
      6 // rebuilding the driver. If the manifest is missing or malformed, the caller falls back to
      7 // the compile-time default — so a bad manifest can never produce a broken driver.
