Directory-as-ID: Scaling Module Discovery Without Configuration

In the previous volume, we explored the vision of an "AI-Perceivable" world. Now, it’s time to go under the hood. The first technical pillar of the apcore protocol is a deceptively simple idea: Directory-as-ID . In a traditional microservices or modular architecture, you often have a central registry, a massive YAML configuration file, or a complex dependency injection container. As your system grows from 10 modules to 1,000, this central "phonebook" becomes a bottleneck. It’s the source of merg
