## Feedback (correction)

**Question:** How do scope cloud WAU numbers compare to PostHog scope_stream_started numbers?
**Tool:** `query`
**Dataset:** `scope_cloud_events, posthog_events, user_daily_engagement`

### Corrected answer
scope_stream_started is injected from rt_scope__cloud_events into posthog_events as a synthetic event. The gap between ClickHouse stream_started and PostHog scope_stream_started is identity resolution — some Scope users aren't matched to a PostHog person_id via person_to_user_ref. user_daily_engagement uses external identified users only and is the canonical WAU source. ClickHouse cloud events will always run slightly higher due to unmatched users.

### Notes
User clarified that scope cloud stream_started events are injected into PostHog as scope_stream_started. The two sources should theoretically be the same event. Remaining gap is identity resolution via person_to_user_ref. user_daily_engagement has_scope_streaming is the right canonical WAU metric.

Start by reviewing the query and the three named datasets: scope_cloud_events, posthog_events, and user_daily_engagement. Confirm how scope_stream_started and has_scope_streaming are compared, then document or test the corrected relationship and identity-resolution gap; no file or test entry point is provided.
