Explanation

GITHUB_REF is the default GitHub Actions environment variable that holds the full Git ref (e.g., refs/heads/main or refs/tags/v1.0.0) that triggered the workflow. GITHUB_BRANCH and ENV_BRANCH do not exist as default GitHub environment variables. GITHUB_TAG is also not a default variable - tag information is derived from GITHUB_REF when the ref starts with refs/tags/.
