• Create tests for RuntimeInfoContributor
• Update InfoActuatorTest to include runtime info in expected JSON validation
• All tests passing across net8.0, net9.0, and net10.0
• Fixed code style issues (ran cleanupcode.ps1 and addressed findings)
• Removed null check test per team policy

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:

• https://api.github.com/repos/SteeltoeOSS/Steeltoe/actions/runs/21081799139/jobs/60636948503
  • Triggering command: /usr/bin/curl curl -s REDACTED (http 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)
