///     domain enums live there), so this DTO is deliberately primitive: every field is a
///     <see cref="bool"/>, the Commons-local <see cref="AlarmShelvingKind"/> enum, a
///     <see cref="ushort"/> severity, or a <see cref="string"/>. The Runtime host maps its Core
///     <c>AlarmConditionState</c> + <c>AlarmSeverity</c> down to this shape; the SDK
///     <c>OtOpcUaNodeManager</c> projects it back up onto a real <c>AlarmConditionState</c> node.

/// <param name="Confirmed">Whether the clear transition has been confirmed (ConfirmedState).</param>
/// <param name="Enabled">Whether the alarm is enabled (EnabledState); a disabled alarm reports no events.</param>
/// <param name="Shelving">The shelving mode (ShelvingState): unshelved, one-shot, or timed.</param>

///     default (issue #477). It is a pure annotation — it never alters Active/Acked/Retain. Defaults to
///     <see cref="OpcUaQuality.Good"/> so scripted-alarm callers (which stay Good in v1) need not supply it.
