Aryan Agrawal enhanced FOA dependency validation in the facebook/buck2-prelude repository by implementing label-based allowlisting for generated targets. He introduced a new LabelInfo provider within android_library_impl and java_library_impl, enabling granular, policy-driven control over which labels participate in FOA checks. This approach improved build determinism and security by ensuring only approved generated targets are validated, addressing key concerns in dependency management. Aryan’s work, primarily using Bzl and leveraging skills in build systems and code generation, established a robust foundation for scalable FOA policy enforcement. The changes laid groundwork for future automation and broader policy expansion without introducing new bugs.
