During the month, contributed to the sst/opencode repository by developing the Session Replay Attachments Metadata Fidelity feature, which ensures that file attachments and their metadata are accurately preserved across session replays. This work involved implementing a targeted metadata preservation fix in TypeScript and Node.js, supporting a variety of file types to improve the fidelity and consistency of replayed sessions. The approach enhanced data integrity and reduced debugging time for both product and support teams. Collaboration was demonstrated through co-authored commits and clear documentation, reflecting a focus on code quality and maintainability within a full stack development context.
