Combine retained daily aggregates with recent usage without replaying historical records or changing the activation boundary. Complete activation-day metrics and expose the UTC calendar used by legacy history.
Render all 365 calendar dates, size heatmap cells responsively, and soften cell corners. Add regression coverage for history cutoffs, retention, sparse dates, and timezone boundaries.
Add dashboard and overview analytics, health monitoring, provider expense tracking, and announcement updates across the gateway and frontend.
Keep schema migrations free of historical backfills while preserving automatic backfill execution. Bound migration deadlines, run schema preparation before Compose replacement, and anonymize deleted dashboard users.
Include the current documentation cleanup and regression coverage.
