1. Install Ruzzy with the appropriate compiler flags, ensuring clang is used.
2. Set up the environment by exporting `ASAN_OPTIONS`.
3. Create a fuzzing harness (and tracer script for pure Ruby).
4. Run the harness with `LD_PRELOAD` to inject the sanitizer.
5. Monitor the output for crashes and interpret the sanitizer reports.
6. Reproduce and fix any identified vulnerabilities.
