- –make_receipt: Not run: labeled as changing data
- –make_barcode: Not run: labeled as changing data
- –calculate_sales_tax: Not run: labeled read-only, but its has a "amount" input, which usually means it changes something. Skipped to be safe: if it only reads, a clearer description helps AI apps too, or test again with --owner
