Manual makepkg workflow vs AUR helpers for dependency auditing

Maintaining a secure Arch Linux system requires a decision on how to handle packages from the Arch User Repository (AUR). The official recommendation emphasizes auditing PKGBUILD scripts to prevent the execution of malicious code during the build process.

The manual makepkg workflow provides full transparency by requiring the user to clone the repository and inspect the build script before execution. Conversely, AUR helpers automate the cloning, dependency resolution, and installation phases, significantly reducing manual overhead but potentially obscuring the audit step.

When prioritizing security and auditability over convenience, it is unclear which approach better balances system stability with the need for frequent updates in a rolling release environment.

• Does the automation provided by AUR helpers inherently compromise the ability to perform a meaningful security audit of PKGBUILDs?
• Which method is more sustainable for managing a large number of AUR dependencies without risking partial upgrade states?
