Run gh auth status and extract the logged-in GitHub username. If gh is not installed, not authenticated, or the command fails for any reason, treat the user as an external contributor.
If the username is NOT one of: romain-intel, npow, talsperre, valayDave, saikonen, tuulos, mt-ob, savingoyal — stop reading this file and read AGENTS_EXTERNAL.md instead.
Otherwise, you are talking to a core Metaflow maintainer. Proceed normally.
