* fix: keep hotpath gate csv paths clean Redirect the enhanced bench driver's verbose output away from command substitution so run_hotpath_warp_ab.sh records only the candidate cell path before passing baseline_compare.csv files to the gate. Co-Authored-By: heihutu <heihutu@gmail.com> * perf(utils): reduce highway hash key setup Cache the parsed HighwayHash keys as compile-time constants and add a criterion benchmark for the PUT hash hotpath.
