# `List at` source audit Generated 2026-09-22T16:06:26.600219+00:00 by `audit_list_at_sources.py`. Read-only: no database writes, no xAI calls, no cache writes. Command: `audit_list_at_sources.py --limit 50` Keepa tokens consumed: **305** The AI reasonableness check was stubbed to `True` for every row, so `recomputed List_at` is the ARITHMETIC the pricing code produces. The `AI check in play` column says which rows reach that check in production. ## Summary ``` LIST AT SOURCE AUDIT 2026-09-22 16:06:26Z | 50 rows, 305 Keepa tokens sample: visible rows by List_at DESC
