Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• cdn.cypress.io
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node index.js --exec install (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Fixed the CI failure in 6a4f657. The TypeScript errors were caused by process.exit mock implementations using (code?: number) which is incompatible with the actual Node.js signature of (code?: string | number | null | undefined) => never. Updated all three occurrences to use (code?: string | number | null) with a proper numeric coercion.
