Moe Charm (CI) b7085c47e1 Phase 35-39: FAST build optimization complete (+7.13% cumulative)
Phase 35-A: BENCH_MINIMAL gate function elimination (GO +4.39%)
- tiny_front_v3_enabled() → constant true
- tiny_metadata_cache_enabled() → constant 0
- learner_v7_enabled() → constant false
- small_learner_v2_enabled() → constant false

Phase 36: Policy snapshot init-once (GO +0.71%)
- small_policy_v7_snapshot() version check skip in BENCH_MINIMAL
- TLS cache for policy snapshot

Phase 37: Standard TLS cache (NO-GO -0.07%)
- TLS cache for Standard build attempted
- Runtime gate overhead negates benefit

Phase 38: FAST/OBSERVE/Standard workflow established
- make perf_fast, make perf_observe targets
- Scorecard and documentation updates

Phase 39: Hot path gate constantization (GO +1.98%)
- front_gate_unified_enabled() → constant 1
- alloc_dualhot_enabled() → constant 0
- g_bench_fast_front, g_v3_enabled blocks → compile-out
- free_dispatch_stats_enabled() → constant false

Results:
- FAST v3: 56.04M ops/s (47.4% of mimalloc)
- Standard: 53.50M ops/s (45.3% of mimalloc)
- M1 target (50%): 5.5% remaining

0) 今の「正」Phase 39

  • 性能比較の正: FAST buildmake perf_fast
  • 安全・互換の正: Standard buildmake bench_random_mixed_hakmem
  • 観測の正: OBSERVE buildmake perf_observe
  • スコアカード: docs/analysis/PERFORMANCE_TARGETS_SCORECARD.md
  • 計測の正Mixed 10-run: scripts/run_mixed_10_cleanenv.shITERS=20000000 WS=400

1) 現状(最新スナップショット)

  • FAST v3: 56.04M ops/smimalloc の 47.4%
  • Standard: 53.50M ops/smimalloc の 45.3%

※詳細は docs/analysis/PERFORMANCE_TARGETS_SCORECARD.md を正とする(ここは要点だけ)。

2) 原則Box Theory 運用)

  • 変更は箱で分けるENV / build flag で戻せる)
  • 境界は 1 箇所(変換点を増やさない)
  • 削除して速くするlink-out / 大きい削除)は封印layout/LTO で符号反転する)
    • compile-out#if HAKMEM_*_COMPILED / #if HAKMEM_BENCH_MINIMAL)は許容
    • Makefile から .o を外す / コード物理削除は原則しないPhase 22-2 NO-GO
  • A/B は 同一バイナリでトグルENV / build flag。別バイナリ比較は layout が混ざる。
