Qt's QObject signal/slot machinery is the preferred change notification mechanism, but a number of model classes in FIFFLIB, FSLIB and INVERSELIB are deliberately kept free of the moc dependency so they remain header-only or usable from static-library and WebAssembly builds. Those classes derive from UTILSLIB::Subject to publish change notifications to any number of UTILSLIB::IObserver listeners without dragging the QObject machinery in.

The static notifyEnabled flag exists so callers performing bulk updates (e.g. fitting a forward solution) can suspend notifications until the batch completes and prevent a storm of redundant repaints in connected views.
