- Replace GNU \b with portable word-boundary sed patterns in kernel-params - Warn on unknown CLI arguments instead of silently swallowing - Add floor check on recommended_gttsize_mib to prevent negative values - Fix Python operator precedence in benchmark log parser - Add root checks to tuned-profile.sh and rollback.sh - Remove redundant sudo calls (scripts already require root at entry) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
