This issue appears to have been resolved. Here's a summary of what we found:

1. The NGC server-side INTERNAL_ERROR for guest-access resources has been fixed — the CI hotfix that switched tests from source=ngc to source=pbss (commit 1df0176a) was reverted on 2025-02-26 in commit 5bd0e2c7, which removed the FIXME referencing this issue.
2. The default_ngc_client() function in load.py already includes a guest-fallback mechanism (added in PR catch ngc api key validation errors and default to not using an api key #635) that catches ValueError from invalid API keys and falls back to a no-apikey guest client.
3. No remaining workarounds or FIXME comments referencing this issue exist in the current codebase.
4. Tests on the main branch currently use NGC as the default download source, suggesting NGC downloads are working correctly.

Closing this as completed. If you still experience issues downloading resources without an NGC API key, please open a new issue with updated reproduction steps.
