///     Crosses every <c>ab_server</c> compose profile with both AbCip transports so each integration
///     test runs once on libplctag and once on the native managed stack. The native run must be green

/// </summary>
/// <remarks>
///     Every AbCip compose profile binds host <c>:44818</c>, so only one can run at a time. When
///     <c>AB_SERVER_COMPOSE_PROFILE</c> is set, <see cref="Profiles"/> keeps only that profile, so the
///     rows match the running container instead of driving, say, Micro800 semantics at a ControlLogix.
///     Unset, only the default ControlLogix profile is crossed: ab_server does not self-identify its
///     <c>--plc</c> mode, so crossing every family at whichever container holds <c>:44818</c> failed the
///     non-matching rows instead of skipping them. Set <c>AB_SERVER_COMPOSE_PROFILE</c> to the running
///     profile (<c>compactlogix</c> / <c>micro800</c> / <c>guardlogix</c>) to select another family.
