Edit a product you own, or pause and resume it. Only the fields you send change.

Body: product_id plus any of name, description, value_prop, target_audience, anchor_sentences (same rules as add_product), buy_signal_keywords, competitor_keywords, active. active=false pauses the product: the scout stops reading its stations and /signal/score no longer accepts its id until it is resumed. Products are paused rather than deleted, because leads, missions and prospects keep their history.
