# run-flywheel-composite

`station__microgram__run-flywheel-composite` · external (needs EXECUTION_BACKEND_URL configured) · domain `microgram` · pv-relevance `pv-core`

Composite flywheel health gate combining event flow, velocity band, and tier coverage. GREEN (healthy+fast+covered), YELLOW (any warning), RED (any critical failure).

> **Note:** This tool routes through an external execution backend. If `EXECUTION_BACKEND_URL` is unset on the server, calls return JSON-RPC error `-32603 "Tool execution backend not configured"`. Tools with `backend: native` execute in-process and are always callable.
