- Watch for
- Every stage starts from the original tables; recompute what you need.
- Use one delivery per event_id: the earliest received_at, ties by the lowest delivery_id.
- Times are UTC. The checkout window is checkout_started at or after pricing_viewed, then subscription_started for the same workspace within 24 hours after checkout.
- Skill
- Prioritize by impact, not only by rate. Refresher: RANK & DENSE_RANK →
