Worked on the sorbet/sorbet repository to address a reliability issue with sealed modules, focusing on improving the accuracy of call stack resolution for included and extended methods. By refining the caller resolution logic in Ruby, the update reduced the risk of incorrect inheritance validation and enhanced the stability of module sealing behavior. This targeted bug fix supports more predictable code analysis for projects that depend on sealed modules, decreasing false positives and maintenance overhead. The work was part of ongoing efforts to strengthen Sorbet’s core analysis, leveraging software development expertise to improve the robustness and reliability of the codebase.
