The Gateway stamps metadata[key] = {\"kind\": <one of kinds>, \"provider\"?: ..., \"namespace\"?: ...} on runs started by a server-side launcher, and on the thread when it creates one (backend/packages/harness/deerflow/runtime/run_origin.py); runs.origin_kind holds the kind. The frontend reads the same key to pick a thread's origin marker. Not to be confused with scheduled_origin_key in scheduled_goal_notes_contract.json, which marks the scheduled prompt message inside a run.",
