Worked on the neoforged/NeoForge repository to enhance the reliability and data integrity of the resource filtering subsystem. Addressed a critical bug by coupling namespace and path checks into a unified predicate, ensuring consistent validation and preventing resource leakage across namespaces. This targeted fix resolved the MC-271761 issue, reducing the risk of cross-namespace leaks and improving the stability of resource management. The approach emphasized maintainability and traceability through focused code changes and clear commit documentation. Utilized Java and backend development skills to deliver a robust solution that strengthens the resource filtering pipeline and supports long-term maintainability within the NeoForge project.
