Original practice card
Use one fixed example for a fair comparison.
Example plan, adjustable: preparation 5 minutes; baseline 2 minutes; two contrast takes 4 minutes; playback 5 minutes; notes 2 minutes. Objective: make “The key is still inside” sound like a practical discovery, not an accusation.
How should the first pass work?
Read the original example and limits, then work through the six steps using your own notes and any equipment required by the task. Keep a baseline or current version and check the stated result before marking a step complete. The checklist records your progress locally; it does not inspect files, judge audio, or perform the task for you.
