These are suggested user procedures, not claims that automated tests have been performed. Each workflow has a concrete outcome to inspect.
Use a small dataset with a refund, an absent category and a blank cell. Predict the answer before calculating it, change one input and verify the change. A plausible-looking total is not a correctness check. The 30/28 example is an arithmetic reference, not a claim of a completed application test.
Choose view, suggest or edit permissions intentionally. Add a comment to the relevant cell rather than sending an unexplained number. Ask the reviewer to check inputs and formula range. Review suggestions before accepting them, and export a dated copy when the workbook is agreed.
Ask for one hint without editing cells, attempt the formula yourself, then ask how to test it. Change an input and explain the new result. The learning goal is a calculation you can inspect and repeat; AI agreement alone does not certify that it is correct.
