            ```

            ## Change checklist
            - [x] User facing
            - [ ] Documentation update

            ## Issues

            - NA

            ## AI-WATERMARK

            AI-WATERMARK: yes

            - If yes:
              - Tools: GitHub Actions (`sync_provider_models.yml`)
              - Model(s): N/A (scripted automation)
              - Scope: Automated model list sync
              - Human verification: Requires manual review before merge

            ## Testing

            - Script dry-run passed in CI
            - Changes are add-only; stale/deprecated models flagged for manual review

            ## Documentation
