message: The review found two narrow behavior issues that tests did not pin down: draft/expired discounts were shown as active in the edit form, and the status filter did not exactly match the effective-status logic for disabled rows. I’m patching those and adding focused assertions, plus a combined explicit+automatic pricing test.
