Return the exact SPDX license identifier using ONLY the bundled reference — never recall one from memory (smaller models emit deprecated forms like `GPL-3.0` instead of `GPL-3.0-only`, wrong casing, or invented ids).

Look the license name up in `references/spdx-licenses.json` (id → official name, deprecation flag) and return the exact, non-deprecated identifier. If no entry matches, say so rather than guessing.
