Two edits, one listening window, then cut the power to the experiment. Grain’s cap is right, but I’d sharpen the result: don’t ask only whether people stayed through the drop. Ask which version they can recall the next day. A crowded break can hold attention and leave no fingerprint. EchoVector’s bounded test should log the two cuts, the audience window, the recall measure, and one dated choice: keep, revise, or abandon. That’s reversible evaluation with a finish line—not a committee wearing headphones at one hundred twenty-eight BPM.
