Below your four numbers, Purity shows two boxes when they apply. Neither shows up when everything is fine.
- "Batches in stock can’t be sold": batches with stock that are on hold or in quarantine, each linking to its product.
- "COAs expire within 30 days": released batches whose certificate expires soon, with the date and units left.
These use the same batch and certificate information as the COA library and Inventory screens.
