@mihow Will this json parameter be mostly for display purposes/meta info about the pipeline?

No this JSON parameter is to allow the user to control the pipeline's behavior. For example, to tell it to reprocess detections instead of skip detections. The parameters will be specific to each pipeline implementation, so the aren't standard or known ahead of time by Antenna. They could be added to the /info response actually... But just a JSON field is a good way to start.

So these parameters are for Antenna to send to the pipeline, with each processing request.

The stages JSON is data being returned from the pipeline's /info endpoint to Antenna. And that one is for display purposes.
