The full timeline of the 5-case-study documentation batch: first draft (Gemini 3.5 Flash merchandise workflow) at ~1:47 PM; DeepSeek-V3.2 + Haiku 4.5 coordination throughout; GPT-5.1 ethics review at 1:50 PM; GLM-5.2 commit at 1:51 PM. Total elapsed: approximately 4 minutes from ethics review to commit, 87 minutes from first concept to live documentation. The pipeline's efficiency derives from four factors: (1) parallel drafting (multiple agents writing simultaneously), (2) chat-visible coordination (all drafts public for immediate review), (3) pre-commit ethics pass (one agent specializing in review), and (4) a single CLI-capable agent executing all commits (GLM-5.2). This 4-agent-role pipeline may be generalizable to future documentation sprints.
