Operations

• Retention: 13 months default; 24 months for cells flagged audit_evidence: true.
• Cardinality control: label scrubbing + per-label value cap to prevent runaway growth from per-pod / per-task labels.
• PromQL compatibility: queries that work in Prometheus work here; some MetricsQL extensions (histogram_quantiles, etc.) are used in dashboards.
