Experiment Analysis Problem

Scenario

You work on a customer product team running an A/B test on a new experience. The team has been checking results repeatedly during the test, and there are concerns that multiple comparisons across metrics or segments may be inflating false positives.

Question

How would you handle peeking or multiple comparisons when analyzing the experiment, and what would you pre-register so the final decision is statistically sound?
