Process-Oriented Programming (POP) is a workflow-centric architectural paradigm designed to enhance transparency, controllability, and maintainability in modern software systems. While version 1.0 established the foundational concepts of explicit processes and layered contexts, version 2.0 introduces a rigorous 3-Axis Context Model implemented in the Theus engine. This evolution addresses the complexities of large-scale systems by introducing “Context Zones” (Data, Signal, Meta) to enforce semantic safety, deterministic replayability, and granular auditability without sacrificing developer ergonomics. POP v2.0 serves as a superior architecture for complex domains like AI agents, robotics, and automation, where the collaboration between human developers and AI coding assistants is paramount.
