Subscription Commerce Analytics Path · Mission 13 of 25Hard

Find late-arriving events

Surface the snapshot-vs-event drift gotcha at the event grain. Practice computing date arithmetic (posted_at::date - event_ts::date), filtering on a column-vs-column comparison, and producing a short audit report. The 30 rows this returns are the seed for M23's deeper reconciliation report.
