The operations coordinator at Bellwick Theater needs a usable stock count before the next event. The source combines entries from several volunteers. Some tags have padding, areas use different case, one row is blank, and an entire count record appears twice. A zero count is valid and tells the coordinator what must be restocked.
Use the skills you have already practiced to fix each requested issue. Every task starts from the state shown, so inspect the preview rather than assuming the previous answer is still present. Choose duplicate keys carefully: several different items can belong to one area. The final handoff needs a small, predictable schema that the coordinator can filter without reading internal notes. Keep source records unless the prompt gives a reason to remove them.
