Worked on the Homebrew/homebrew-core repository to enhance cross-architecture reliability for the Composer formula by addressing installation issues specific to ARM systems. Focused on aligning the pour_bottle guard logic for ARM with the existing Intel implementation, the work applied the same pour_bottle limit to ARM, reducing failures related to non-default prefixes. This update ensured consistent behavior across both ARM and Intel architectures and maintained compatibility with upstream changes from composer/ca-bundle. The solution was implemented using Ruby and leveraged expertise in Homebrew and package management, demonstrating careful attention to formula logic and end-to-end consistency for users on multiple platforms.
