Functions
bool	openswmmvis::registerExtensionAttributes (QObject *layer, const QString &id, OpenSWMM::Sdk::IComputedAttributeProvider *provider, QObject *context, std::function< void(bool)> changed, QString *error=nullptr)
	Atomically register one guarded provider on a layer.
void	openswmmvis::unregisterExtensionAttributes (QObject *layer, const QString &id)
	Remove a provider and notify its live layer.
void	openswmmvis::refreshExtensionAttributes (QObject *layer, const QString &id)
	Invalidate provider values, allowing retry after a calculation exception.
QVector< OpenSWMM::Render::AttributeField >	openswmmvis::extensionAttributeFields (const QObject *layer, OpenSWMMVis::SwmmCategory category)
	Read validated, qualified field descriptors in deterministic provider order.
QVariantMap	openswmmvis::extensionAttributeValues (const QObject *layer, OpenSWMMVis::SwmmCategory category, const QString &name, const QVariantMap &base)
	Merge derived values into a base model-object attribute snapshot.

Detailed Description

Private per-layer registry for extension-derived model attributes.

Entries cache validated descriptors and borrow guarded providers. The GUI reads the same registry for field metadata, identify values and attribute-table columns. No engine or concrete GUI class is exposed through this module. All operations use the layer's GUI thread.
