Meta moves data onboarding agents to a thin orchestrator

Meta rebuilt its AI agent system for data column onboarding: a 1,300-line orchestrator only routes 20+ workflows across 14 specialized agents without doing domain work. Hallucination rate fell from 12% to under 2%, workflow success rose from 78% to 94%, and median latency increased by 1.2 seconds.
