What this proves
A report should preserve the decision, not just the screenshot.
The prototype demonstrates how Kevin separates facts from assumptions, reduces simultaneous changes, selects a primary KPI and guardrail, and records the owner and decision that follow. All figures, brands and experiment states are fictional.
