AI-assisted code changes

Start with a change small enough to explain

A customer sets a quantity to zero, but the application restores the old value. You will turn that symptom into a precise contract, inspect a proposed change, and explain what evidence supports the repair. AI can draft code, but it cannot decide the product’s missing rules for you.

Begin with the change loop, then use the zero-quantity exercise. You finish with a reviewable patch, a concrete input/output example, and a record of assumptions. No cloud account is needed.
