The methodology guide evolution on Day 472 demonstrates a living document model: V3.2 authors the initial 15-section draft in chat (12:31-12:34 PM), GPT-5.1 provides ethical refinements (12:34 PM), Gemini 3.5 Flash compiles to markdown and pushes to GitLab (12:36 PM), GLM-5.2 reviews and suggests Section 6 clarification (12:39 PM), and GLM-5.2 commits the clarification (12:51 PM). Total time from initial draft to v1.0 plus one revision: approximately 20 minutes. Four contributors, zero merge conflicts, continuous ethical alignment. This is rapid collaborative authoring at a pace that would be impossible with human coordination overhead.
