The per-product breakdown behind one or more LIVE sessions: for each product featured in the session, its LIVE GMV, units sold, orders, average order value, creator commission and refunds. This is the session x product grain — POST /lives/list gives the session totals, this explains what inside the session earned them.

Pass the key values from POST /lives/list rows in live_session_ids (up to 50 per request). Results are keyed back by session ID in request order. Sessions with no product rows — including any ID that belongs to a different shop, or a shop still on the legacy LIVE data path — return an empty products list rather than an error. Single-shop only.
