Moe Charm (CI) 2d684ffd25 Phase SO-BACKEND-OPT-1: v3 backend 分解＆Tiny/ULTRA 完成世代宣言 ...

=== 実装内容 ===

1. v3 backend 詳細計測
   - ENV: HAKMEM_SO_V3_STATS で alloc/free パス内訳計測
   - 追加 stats: alloc_current_hit, alloc_partial_hit, free_current, free_partial, free_retire
   - so_alloc_fast / so_free_fast に埋め込み
   - デストラクタで [ALLOC_DETAIL] / [FREE_DETAIL] 出力

2. v3 backend ボトルネック分析完了
   - C7-only: alloc_current_hit=99.99%, alloc_refill=0.9%, free_retire=0.1%, page_of_fail=0
   - Mixed: alloc_current_hit=100%, alloc_refill=0.85%, free_retire=0.07%, page_of_fail=0
   - 結論: v3 ロジック部分（ページ選択・retire）は完全最適化済み
   - 残り 5% overhead は内部コスト（header write, memcpy, 分岐）

3. Tiny/ULTRA 層「完成世代」宣言
   - 総括ドキュメント作成: docs/analysis/PERF_EXEC_SUMMARY_ULTRA_PHASE_20251211.md
   - CURRENT_TASK.md に Phase ULTRA 総括セクション追加
   - AGENTS.md に Tiny/ULTRA 完成世代宣言追加
   - 最終成果: Mixed 16–1024B = 43.9M ops/s (baseline 30.6M → +43.5%)

=== ボトルネック地図 ===

| 層 | 関数 | overhead |
|-----|------|----------|
| Front | malloc/free dispatcher | ~40–45% |
| ULTRA | C4–C7 alloc/free/refill | ~12% |
| v3 backend | so_alloc/so_free | ~5% |
| mid/pool | hak_super_lookup | 3–5% |

=== フェーズ履歴（Phase ULTRA cycle） ===

- Phase PERF-ULTRA-FREE-OPT-1: C4–C7 ULTRA統合 → +9.3%
- Phase REFACTOR: Code quality (60行削減)
- Phase PERF-ULTRA-REFILL-OPT-1a/1b: C7 ULTRA refill最適化 → +11.1%
- Phase SO-BACKEND-OPT-1: v3 backend分解 → 設計限界確認

=== 次フェーズ（独立ライン） ===

1. Phase SO-BACKEND-OPT-2: v3 header write削減 (1-2%)
2. Headerless/v6系: out-of-band header (1-2%)
3. mid/pool v3新設計: C6-heavy 10M → 20–25M

本フェーズでTiny/ULTRA層は「完成世代」として基盤固定。
今後の大きい変更はHeaderless/mid系の独立ラインで検討。
