  Tenant-wide blocking-rule/IOC capacity has reached 95% - new rules or IOCs may soon fail to be added. Emitted by the daily tenant health-check job (api/src/functions/tenantHealthChecks.js) when usage newly crosses this threshold, and re-emitted at most once per ~30 days while it remains above threshold.
