Experiment: [what changed]. Primary metric: [metric]. Results: control n=[n], conversions=[x]; variant n=[n], conversions=[y]. Duration: [days]. Secondary metrics: [list]. Analyze: absolute and relative lift with 95% CI, p-value (state the test used), whether the test was adequately powered, risks (novelty effect, peeking, sample ratio mismatch), and a clear recommendation: ship, iterate or stop. Show calculations.
