Worked on the gohugoio/hugo repository to enhance the reliability of content conversion workflows by ensuring non-content files are preserved during the hugo convert process. Developed a feature in Go that copies the entire content tree to the destination before overwriting converted files, which helps retain bundle resources and prevents loss of non-content assets. Added safeguards to skip recursive copying when the output path is inside the content tree, addressing potential workflow issues. This backend development effort directly responded to user-reported concerns, aligning with issue #4621, and improved the stability and predictability of conversion pipelines for Hugo users.
