Preserve user-provided complete CPU and HIP logs and associate the optimized implementation with e1ec480669. Record matching event counts, user-confirmed bit-identical PNG output, and the 2.77x workflow speedup with tracing/import differences noted.
Mark the pre-artifact-fix CPU benchmark as historical and link the new paired result.
