# run-algo-void-scan

`station__microgram__run-algo-void-scan` · external (needs EXECUTION_BACKEND_URL configured) · domain `microgram` · pv-relevance `pv-core`

Algorithm 9 (VOID): Detect what's missing. Compares expected data elements against what's present, returns gap count and verdict. κ(ς, ∅) at ∂ → Σ.

> **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.
