Reference answer

Pair a north-star with hygiene metrics. North-star: weekly active creators with one substantive artifact. Secondary: time-on-task completed without abandonment; feature-specific: list-edit rate, share frequency.

Define features and behaviors to log at ingestion time so the metric isn't deadlock-locked.
