Worked on improving cross-platform reliability for the penpot/penpot repository by addressing architecture detection issues in deployment scripts. Focused on shell scripting, the developer enhanced the manage.sh script to correctly identify and handle AMD64 systems, resolving previous misclassification problems that could disrupt builds on 64-bit environments. This update stabilized build processes and improved deployment consistency across different platforms. The work involved careful modification of architecture detection logic, ensuring that AMD64 support was seamlessly integrated without affecting existing functionality. Throughout the process, standard commit practices were maintained to ensure governance and traceability, reflecting a methodical approach to shell scripting and deployment automation.
