Investigate daily config_machines drift update failure

[Copilot]

Daily drift was detected for config_machines.xml, but the required sync command
could not complete in this environment due a GitHub API authorization failure.
As a result, no config or Spack template updates were applied yet.

• Required update path execution

  • Ran:

    pixi run -e py314 python utils/update_cime_machine_config.py --work-dir .

  • Script failed while resolving upstream revision from GitHub API
    (403 Forbidden in _get_latest_commit_sha).

• Repository changes

  • No repository files were changed.
  • mache/cime_machine_config/config_machines.xml was not replaced because
    upstream_config_machines.xml was not generated successfully.

• Upstream context from issue

  • Upstream E3SM commit hash to use once API access is unblocked:
    4487cd1c5daf8ab1de910a9d0c74be4b8e813bfb.

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/E3SM-Project/E3SM/commits
  • Triggering command: /home/REDACTED/work/mache/mache/.pixi/envs/py314/bin/python /home/REDACTED/work/mache/mache/.pixi/envs/py314/bin/python utils/update_cime_machine_config.py --work-dir . (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)
