    /// When a project upgrades from such a version, that instance survives the domain reload triggered
    /// by the upgrade - but only if its serialized script reference still resolves. That reference is
    /// <c>{ fileID: 11500000, guid: &lt;this file's guid&gt; }</c>, so this file MUST keep the original
    /// <c>InputSystemObject.cs</c> GUID (<c>5cdce2bffd1e49bda08b3db54a031207</c>) and this MUST be the
    /// primary class of the file (matching the file name). If the reference fails to resolve, Unity
    /// drops the object during the reload and the input state - including the list of connected devices
    /// - is lost on upgrade, with no in-process recovery (native only re-reports devices once per editor
    /// process). See ISX-2569.
