research-hub-multi-ai

Research-domain router that writes .coord/multi_ai_plan.md when one round needs two or more bounded delegates and touches .research/, .paper/, Zotero, Obsidian, or NotebookLM artifacts. Supported leaves are codex-delegate and antigravity-delegate; long-context, CJK, judgment, and review work stay with the primary model. Use the generic agent-collab task splitter for non-research work.
