Recommended action: Lowercase the image name before use (e.g. ${VAR,,} in bash, or tr '[:upper:]' '[:lower:]'); tags may contain uppercase but repository names may not.
Option: Lowercase the repository name [evidence: documented_workaround]
Applies when: See record scope.
Steps:
1. IMAGE=$(echo "ghcr.io/$GITHUB_REPOSITORY" | tr '[:upper:]' '[:lower:]')
2. docker build -t "$IMAGE:tag" .
Expected: Command proceeds without the error.
