failed to list artifacts of repository

Error message

failed to list artifacts of repository %s: %v

What it means

Returned inside a concurrent FetchArtifacts task when listing artifacts for a single GitHub Container Registry repository fails. It wraps the per-repository error with the repo name; the failure comes from the GitHub API (rate limiting, auth, or connectivity) and aborts that repo's task in the limited-concurrency runner.

Solutions

1. Check GitHub API rate limits and personal access token scopes (read:packages)
2. Verify network connectivity to ghcr.io / api.github.com
3. Retry the operation; GitHub API rate-limit errors are transient
4. Inspect the wrapped error to identify the failing repository and root cause
