  "description": "OpenTrackIO binding — one virtual-production take. The camera and its tracker are infrastructure; the recorded stream of tracking samples is an asset that carries the source id the tracker emitted; a QC task checks the log before a render task uses it against a USD scene. The live UDP stream stays outside the graph. OWG records what was captured, on what, and what consumed it. The take's timecode range sits in an x- metadata key, because the schema's timerange field is documented for TAMS syntax only.",
  "objective": "Record the tracking data for a take as a governed asset, check it, and use it to render a background that matches the camera move, with the lineage intact.",
