Counts are events Slashr observed, bounded per chain by monitoring_since. A chain's history before that date is not covered and must not be inferred from these figures.

A chain shows a slashing count only where its protocol reduces principal stake. Downtime on a chain with no slashing mechanism is an outage, not a penalty, and is counted as an event only.
