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+; inspect the source before using it on your own files.
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.jsonRead the result
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.
Where this check stops
This local walkthrough does not establish the state of a live production system or replace the limits documented in the repository.
Before adapting the command to your own workflow, review the accepted inputs, exit codes and safety boundaries in the README.
Compiled with AI assistance from checked-in public documentation and example scripts. Run the example and review the repository's current documentation before relying on its result.
