• Health — GET /api/v1/health
  Fetch global health summary.
• Health History — GET /api/v1/health/history/{date}
  Fetch compact daily health history.
• Health Trends Bulk — GET /api/v1/health/trends
  Fetch compact 7d/30d daily uptime and latency trends for all subnets (computed live from the store).
• Incidents — GET /api/v1/incidents
  Fetch recent cross-subnet downtime incidents reconstructed from probe history over a 7d or 30d window (computed live from the store).
• Self Health — GET /api/v1/self-health
  metagraphed's OWN uptime: a verdict scoped strictly to our own components (api / site / publish) plus each one's trailing-90-day daily uptime ratios and latest probe state, served from the self_health_daily lakehouse rollup at /api/v1/self-health (no static file).
• Subnet Health — GET /api/v1/subnets/{netuid}/health
  Fetch health detail for one subnet.
• Subnet Health Incidents — GET /api/v1/subnets/{netuid}/health/incidents
  Fetch SLA (uptime ratio) and reconstructed downtime incidents per operational surface for one subnet over a 7d or 30d window (computed live from the store).
• Subnet Health Percentiles — GET /api/v1/subnets/{netuid}/health/percentiles
  Fetch latency percentiles (p50/p95/p99) per operational surface for one subnet over a 7d or 30d window (computed live from the store).
• Subnet Health Trends — GET /api/v1/subnets/{netuid}/health/trends
  Fetch 7d/30d uptime and success-only latency trends (mean + p50/p95/p99 tail + healthy-sample count) per operational surface for one subnet (computed live from the store).
• Subnet Uptime — GET /api/v1/subnets/{netuid}/uptime
  Fetch long-term daily uptime history per operational surface for one subnet over a 90d or 1y window (computed live from the surface_uptime_daily rollup).
