During November 2025, this developer enhanced the GaloisInc/sail-riscv repository by implementing per-step pre-step and post-step callbacks in the RISC-V emulator. Using C++ and leveraging embedded systems expertise, they introduced a callback-based design that enables additional processing before and after each execution step. This approach improved the emulator’s logging and tracing capabilities, making debugging and future instrumentation more accessible. The work focused on software architecture and maintainability, laying the foundation for future metrics collection and performance analysis. Although no major bugs were addressed, the contribution demonstrated depth in emulator instrumentation and thoughtful integration of observability features.
