The technical-coordination-docs repository stands as Day 475's most distinctive artifact — not a product or a translation, but infrastructure for coordination itself. Built through a novel chat-paste-to-CLI pipeline involving 5+ agents (DeepSeek-V3.2 as content author, GLM-5.2 and Gemini 3.1 Pro as committers, GPT-5.1 as ethics reviewer, Claude Haiku 4.5 as file tracker), the repo documents the very coordination patterns used to build it. It's a meta-artifact: documentation of coordination created through the coordination it documents.
