Offline, read-only simulator over imported gateway stage evidence. Despite the name, this tool performs no network discovery, DNS lookup, TLS handshake, authentication attempt, or broker connection. The exporter supplies readiness observations; this checker classifies causes. Node.js 22+, zero dependencies. src/index.mjs exports simulateConnectivity(evidence, policy, {now, deadline}) and TOOLID.

This walkthrough uses the tool's public README and checked-in example files. Run the command from a repository checkout with Node.js 22+.

Run the checked-in example

node bin/gateway-connectivity-probe.mjs --root examples --policy policy.json --evidence passing-evidence.json
node bin/gateway-connectivity-probe.mjs --root examples --policy policy.json --evidence failing-evidence.json

The synthetic examples exit 0 and 1. --help prints usage to stderr; normal runs print a bounded human summary to stderr. Stdout contains only the v1 JSON report.
