Summary: - D1 (Free route cache): 20-run validation → PROMOTED TO DEFAULT - Baseline (20-run, ROUTE=0): 46.30M ops/s (mean), 46.30M (median) - Optimized (20-run, ROUTE=1): 47.32M ops/s (mean), 47.39M (median) - Mean gain: +2.19%, Median gain: +2.37% - Decision: GO (both criteria met: mean >= +1.0%, median >= +0.0%) - Implementation: Added HAKMEM_FREE_STATIC_ROUTE=1 to MIXED preset - D2 (Wrapper env cache): FROZEN - Previous result: -1.44% regression (TLS overhead > benefit) - Status: Research box (do not pursue further) - Default: OFF (not included in MIXED_TINYV3_C7_SAFE preset) - Baseline Phase 3: 46.04M ops/s (Mixed, 10-run, 2025-12-13) Cumulative Gains (Phase 2-3): B3: +2.89%, B4: +1.47%, C3: +2.20%, D1: +2.19% Total: ~7.6-8.9% (conservative: 7.6%, multiplicative: 8.93%) MID_V3 fix: +13% (structural change, Mixed OFF by default) Documentation Updates: - PHASE3_FINALIZATION_SUMMARY.md: Comprehensive Phase 3 report - PHASE3_CACHE_LOCALITY_NEXT_INSTRUCTIONS.md: D1/D2 final status - PHASE3_D1_FREE_ROUTE_CACHE_1_DESIGN.md: 20-run validation results - PHASE3_D2_WRAPPER_ENV_CACHE_1_DESIGN.md: FROZEN status - ENV_PROFILE_PRESETS.md: D1 ADOPT, D2 FROZEN - PHASE3_BASELINE_AND_CANDIDATES.md: Post-D1/D2 status - CURRENT_TASK.md: Phase 3 complete summary Next: - D3 requires perf validation (tiny_alloc_gate_fast self% ≥5%) - Or Phase 4 planning if no more D3-class targets - Current active optimizations: B3, B4, C3, D1, MID_V3 fix Files Changed: - docs/analysis/PHASE3_FINALIZATION_SUMMARY.md (new, 580+ lines) - docs/analysis/*.md (6 files updated with D1/D2 results) - CURRENT_TASK.md (Phase 3 status update) - analyze_d1_results.py (statistical analysis script) - core/bench_profile.h (D1 promoted to default in MIXED preset) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
