Use `get_performance` with platform='meta', entity_type='adset', date_range={\"days\": 7} for each ad set's 7-day spend and conversions (get_entities does not attach metrics for ad sets - only campaigns). Flag: conversions < 50 (Meta's learning threshold), and spend > 0 with conversions = 0. Only the ad set's CURRENT status is available (via `get_entities` with entity_type='adset') - there is no status-change history, so paused/re-enabled loops cannot be detected.\n"
