 Prepared cards in the authenticated outreach funnel expose the exact opener, grounded image analysis, attractiveness and physique scores, current target range, detected gender, strategy/tone/model metadata, and original source image. The live range is returned through the existing preparation field so cached dashboard bundles remain compatible during a rolling deployment.
