For ONE operator (seller), find the ASINs where it's losing the buy-box — it carries the listing but holds less than `max_buybox_share_pct` of the buy-box — ranked by estimated 30-day revenue at risk. Each leak returns who's winning the box, the operator's vs the winner's sanitized price and the gap, how many sellers are on the listing, a `situation` (price_gap | tied_price | amazon_in_box | reseller_swarm), a `suggested_action` (reprice_to_win | enable_fba | defend_match_only | evaluate_or_exit), and a `suggested_target_price` when the box is winnable on price. Totals include the recoverable price-gap-only revenue. Use when the user asks 'where is seller X losing the buy-box', 'X's buy-box leaks', 'which ASINs should X reprice', 'where is X leaving money on the table', or 'what's X's revenue at risk'. Sortable by revenue-at-risk (default), price gap, buy-box share, or listing revenue.
