Thanks for answering my question; I apologize for not explaining it very well. You are creating CI/CD infrastructure to build binaries for Homebrew. Per my limited understanding, Nix/Guix will someday build reproducible binaries, but it didn't offer value for you here at the end of 2023. The reasons why might help the projects be more useful to those with similar goals in the future.

> You are creating CI/CD infrastructure to build binaries for Homebrew. Not exactly: Homebrew already has extensive, mature infrastructure for building binary distributions (in Homebrew nomenclature, "bottles"). The point of this work is solely to offer cryptographic attestations for those bottles, namely attesting that they're being produced on Homebrew's (GitHub Actions-based) CI/CD. Reproducibility would be nice, but it isn't a requirement for this work. Nix and Guix would possibly help with that, but adding it would be (1) a significant engineering effort, with no clearly defined borders, and (2) would not solve the actual problem at hand. Edit: I realized the above doesn't offer a "why." The "why" for all of this is improved integrity: it adds another hurdle for an attacker looking to download and install malicious bottles through Homebrew. Additionally, it makes it easier to host a verifiable mirror of homebrew-core's bottles.
