Worked on the go-gitea/gitea repository to enhance the reliability of repository templating by addressing a bug related to exclusive label sort order. Focused on backend development using Go, the contribution ensured that when a new repository is created from a template, the original order of exclusive labels is preserved. This fix eliminated the need for manual label reordering after repository creation, streamlining user workflows and reducing support overhead. The solution involved careful handling of data structures to maintain deterministic label ordering, directly resolving issues #36463 and #36931. The work demonstrated attention to detail and a methodical approach to backend stability.
