Worked on stabilizing the Rerun-Viewer example in the dora-rs/dora repository by addressing configuration and compatibility issues. Updated the dataflow YAML to reference the correct dora-rerun executable, ensuring the example runs as intended across different environments. Aligned the tracing function naming for improved compatibility and specified Python 3.11 for virtual environment creation, which helps maintain reproducibility and reduces onboarding friction for new contributors. The work focused on build system and example configuration, utilizing Rust and YAML to enforce environment consistency. This targeted bug fix improved reliability for developers working with the example, supporting smoother collaboration and more predictable development workflows.
