How would you define primary, secondary, and guardrail metrics for a new feature at Uber Freight? Explain how you would connect the feature's intended user and business outcome to a measurable metric hierarchy, select appropriate denominators and time windows, and identify risks that guardrails should detect. Describe how you would validate the definitions before launch and evaluate the feature after release.
