Interview Prompt
A metrics platform stores fully-qualified metric names like 'bookings.checkout.success_rate', and dashboards autocomplete a metric from any contiguous piece of its name. For each metric, find the shortest contiguous substring of its name that appears in no other metric's name, and return those results aligned with the input list.
Summary
One token per metric. Make it unambiguous.
