Get User Stats

Platform user-activity rollup for the admin dashboard.

"Active" is keyed on model usage (a token_usage row), not logins: a session-bearing user who never runs the agent isn't active in any sense that matters for this product.

Two families of numbers ship together:

• Engagement KPIs (average_dau/wau/mau/stickiness). wau and mau are distinct active users in the trailing 7/30 days (the standard Amplitude/Mixpanel definitions). average_dau is the mean daily active users over the trailing average_dau_days window (a single day is too noisy to headline). stickiness is always the trailing 30-day average DAU over mau, regardless of average_dau_days.
• Trend data (daily_active_users) is the per-day distinct-user series scoped to the caller-selected range_days lookback; it drives the activity heatmap. The series is sparse (zero-activity days omitted), so callers averaging it must divide by range_days, not by its length.
