// Gateway Health: MCP Gateway and LLM Gateway sections, both fetched from rollup_server.py, which lives in the
// macrodata-refinement repo at OTHER_APPS/gateway_health/rollup_server.py (this repo has no backend).
// Bucket = { t, state: 'operational'|'degraded'|'partial'|'major'|'maintenance'|'nodata', p95, errorRate, requests, incidentId }
// Bucket = { t, state: 'operational'|'degraded'|'partial'|'major'|'monitor_disconnected'|'maintenance'|'nodata', p95, errorRate, requests, incidentId }
// monitor_disconnected = the sustained failures behind this bucket never got a response at all
// (the monitoring worker/host itself lost outbound connectivity), not the real gateway
// infrastructure failing - see is_connectivity_error in rollup_server.py.
