  "_hint": "✅ DRC clean. Safe to open kicad_open_board, generate gerbers via export, or hand off to fabrication. No human intervention needed.",
  "_timeoutHint": "ab waits up to 130s for this verb before the request times out. If it's a long operation (cloud open / download / export), DON'T treat a timeout as failure — the work usually keeps running on the bridge. Poll `kicad_status` until it reports done.",
