## Summary - ChatGPT により bench_profile.h の setenv segfault を修正（RTLD_NEXT 経由に切り替え） - core/box/pool_zero_mode_box.h 新設：ENV キャッシュ経由で ZERO_MODE を統一管理 - core/hakmem_pool.c で zero mode に応じた memset 制御（FULL/header/off） - A/B テスト結果：ZERO_MODE=header で +15.34% improvement（1M iterations, C6-heavy） ## Files Modified - core/box/pool_api.inc.h: pool_zero_mode_box.h include - core/bench_profile.h: glibc setenv → malloc+putenv（segfault 回避） - core/hakmem_pool.c: zero mode 参照・制御ロジック - core/box/pool_zero_mode_box.h (新設): enum/getter - CURRENT_TASK.md: Phase ML1 結果記載 ## Test Results | Iterations | ZERO_MODE=full | ZERO_MODE=header | Improvement | |-----------|----------------|-----------------|------------| | 10K | 3.06 M ops/s | 3.17 M ops/s | +3.65% | | 1M | 23.71 M ops/s | 27.34 M ops/s | **+15.34%** | 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
