Detailed Description

struct EntropyEngine::Core::Concurrency::DependencyResolvedEvent;

One step closer - a parent completed and child’s dependency count dropped.

This granular event fires each time a parent node completes and decrements a child’s dependency counter. When remainingDependencies reaches zero, the child becomes ready. Useful for understanding the cascade of execution.

eventBus->subscribe<DependencyResolvedEvent>([](const auto& event) {
    LOG_DEBUG("{} completed, {} now has {} dependencies left",
              event.from.getData()->name,
              event.to.getData()->name,
              event.remainingDependencies);

    if (event.remainingDependencies == 0) {
        LOG_INFO("{} is now ready!", event.to.getData()->name);
    }
});
