MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.80). The GitHub Actions references (actions/checkout@v4, dtolnay/rust-toolchain@stable, taiki-e/install-action@cargo-llvm-cov) are fetched and executed at CI runtime and thus constitute external runtime code dependencies that can execute remote code.
