# Sources Summary

> Top-line Sources KPIs, all real:
* events_per_day — mean daily ingested issues over the trailing window
* active_sources / total_sources — sources with ≥1 issue in the window
* last_ingested_at — most recent arrival across every source
Metrics that cannot be derived from stored data (e.g. historical parse
latency) are intentionally absent rather than fabricated.
