[Copilot]

• Confirm the requested follow-up scope from PR feedback (run investigation on v1 branch)
• Fetch and check out the repository v1 branch for validation
• Re-run Node 16/18 vs Node 20 diagnostics and timing on v1
• If v1 reproduces regressions, implement a minimal fix and validate
• Reply to the PR comment with results and commit hash

@copilot no! I wanted you to check out the v1 branch, and do your testing in there. You did this in a branch off of master. that's wrong.

@copilot no! I wanted you to check out the v1 branch, and do your testing in there. You did this in a branch off of master. that's wrong.

I reran the investigation on the v1 branch as requested (tested at origin/v1 commit 9de11ed). On Node 20, both targeted tests pass there as well (Emits validation events and Calls XML file validation plugins), and timing remained comparable/slightly faster than Node 16/18 in this environment. Current PR branch head: 6a09d87.

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:

• iojs.org
  • Triggering command: /usr/bin/curl curl -q --fail --compressed -L -s REDACTED -o - (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)

I tested this locally as well and couldn't reproduce. Closing.
