Results: - A/B test: +5.18% on Mixed (10-run, clean env) - Baseline: 46.68M ops/s - Optimized: 49.10M ops/s - Improvement: +2.42M ops/s (+5.18%) Strategy: - Eliminate duplicate header validation in front_fastlane_try_free() - Direct call to free_tiny_fast() when dedup enabled - Single validation path (no redundant checks) Success factors: 1. Complete duplicate elimination (free path optimization) 2. Free path importance (50% of Mixed workload) 3. Improved execution stability (CV: 1.00% → 0.58%) Phase 6 cumulative: - Phase 6-1 FastLane: +11.13% - Phase 6-2 Free DeDup: +5.18% - Total: ~+16-17% from baseline (multiplicative effect) Promotion: - Default: HAKMEM_FRONT_FASTLANE_FREE_DEDUP=1 (opt-out) - Added to MIXED_TINYV3_C7_SAFE preset - Added to C6_HEAVY_LEGACY_POOLV1 preset - Rollback: HAKMEM_FRONT_FASTLANE_FREE_DEDUP=0 Files modified: - core/box/front_fastlane_env_box.h: default 0 → 1 - core/bench_profile.h: added to presets - CURRENT_TASK.md: Phase 6-2 GO result Health check: PASSED (all profiles) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
