+## NEW 2025-11-11: Tiny L1-miss増加とUB修正（FastCache/Freeチェイン）
+
+構造方針（確認）
+- 結論: 構造はこのままでよい。`tiny_nextptr.h` に next を集約した箱構成で安全性と一貫性は確保。
+- この前提で A/B とパラメータ最適化を継続し、必要時のみ“クラス限定ヘッダ”などの再設計に進む。
+
+現象（提供値 + 再現計測）
+- 平均スループット: 56.7M → 55.95M ops/s（-1.3% 誤差範囲）
+- L1-dcache-miss: 335M → 501M（+49.5%）
+- 当環境の `bench_random_mixed_hakmem 100000 256 42` でも L1 miss ≈ 3.7–4.0%（安定）
+- mimalloc 同条件: 98–110M ops/s（大差）
+
+根因仮説（高確度）
+1) ヘッダ方式によるアラインメント崩れ（本丸）
+   - 1バイトヘッダで user ptr を +1 するため、stride=サイズ+1 となり多くのクラスで16B整列を失う。
+   - 例: 256B→257B stride で 16ブロック中15ブロックが非整列。L1 miss/μops増の主因。
+2) 非整列 next の void** デリファレンス（UB）
+   - C0–C6 は next を base+1 に保存/参照しており、C言語的には非整列アクセスで UB。
+   - コンパイラ最適化の悪影響やスピル増の可能性。
+
+対処（適用済み：UB除去の最小パッチ）
+- 追加: 安全 next アクセス小箱 `core/tiny_nextptr.h:1`
+  - `tiny_next_off(int)`, `tiny_next_load(void*, cls)`, `tiny_next_store(void*, cls, void*)`
+  - memcpy ベースの実装で、非整列でも未定義動作を回避
+- 適用先（ホットパス差し替え）
+  - `core/hakmem_tiny_fastcache.inc.h:76,108`
+  - `core/tiny_free_magazine.inc.h:83,94`
+  - `core/tiny_alloc_fast_inline.h:54` および push 側
+  - `core/hakmem_tiny_tls_list.h:63,76,109,115` 他（pop/push/bulk）
+  - `core/hakmem_tiny_bg_spill.c`（ループ分割/再接続部）
+  - `core/hakmem_tiny_bg_spill.h`（spill push 経路）
+  - `core/tiny_alloc_fast_sfc.inc.h`（pop/push）
+  - `core/hakmem_tiny_lifecycle.inc`（SLL/Fast 層の drain 処理）
+
+リリースログ抑制（無害化）
+- `core/superslab/superslab_inline.h:208` の `[DEBUG ss_remote_push]` を
+  `!HAKMEM_BUILD_RELEASE && HAKMEM_DEBUG_VERBOSE` ガード下へ
+- `core/tiny_superslab_free.inc.h:36` の `[C7_FIRST_FREE]` も同様に
+  `!HAKMEM_BUILD_RELEASE && HAKMEM_DEBUG_VERBOSE` のみで出力
+
+効果
+- スループット/ミス率は誤差範囲（正当性の改善が中心）
+- 非整列 next の UB を除去し、将来の最適化で悪化しづらい状態に整備
+- mimalloc との差は依然大きく、根因は主に「整列崩れ＋キャッシュ設計差」と判断
+
+計測結果（抜粋）
+- hakmem Tiny:
+  - `./bench_random_mixed_hakmem 100000 256 42`
+    - Throughput: ≈8.8–9.1M ops/s
+    - L1-dcache-load-misses: ≈1.50–1.60M（3.7–4.0%）
+- mimalloc:
+  - `LD_LIBRARY_PATH=... ./bench_random_mixed_mi 100000 256 42`
+    - Throughput: ≈98–110M ops/s
+- 固定256B（ヘッダON/OFF比較）:
+  - `./bench_fixed_size_hakmem 100000 256 42`
+    - ヘッダON: ~3.86M ops/s, L1D miss ≈4.07%
+    - ヘッダOFF: ~4.00M ops/s, L1D miss ≈4.12%（誤差級）
+
+新規に特定した懸念と対応案
+- 整列崩れ（最有力）
+  - 1Bヘッダにより stride=サイズ+1 となり、16B 整列を崩すクラスが多い（例: 256→257B）。
+  - 単純なヘッダON/OFF比較では差は小さく、他要因との複合影響と見做し継続調査。
+- UB（未定義動作）
+  - 非整列 void** load/store を `tiny_nextptr.h` による安全アクセサへ置換済み。
+- リリースガード漏れ
+  - `[C7_FIRST_FREE]` / `[DEBUG ss_remote_push]` は release ビルドでは
+    `HAKMEM_DEBUG_VERBOSE` 未指定時に出ないよう修正済み。
+
+成功判定（Tiny側）
+- A/B（ヘッダOFF or クラス限定ヘッダ）で 256B 固定の L1 miss 低下・ops/s 改善
+- mimalloc との差を段階的に圧縮（まず 2–3x 程度まで、将来的に 1.5x 以内を目標）
+
+トラッキング（参照ファイル/行）
+- 安全 next 小箱:
+  - `core/tiny_nextptr.h:1`
+- 呼び出し側差し替え:
+  - `core/hakmem_tiny_fastcache.inc.h:76,108`
+  - `core/tiny_free_magazine.inc.h:83,94`
+  - `core/tiny_alloc_fast_inline.h:54` 他
+  - `core/hakmem_tiny_tls_list.h:63,76,109,115`
+  - `core/hakmem_tiny_bg_spill.c` / `core/hakmem_tiny_bg_spill.h`
+  - `core/tiny_alloc_fast_sfc.inc.h`
+  - `core/hakmem_tiny_lifecycle.inc`
+- リリースログガード:
+  - `core/superslab/superslab_inline.h:208`
+  - `core/tiny_superslab_free.inc.h:36`
+
+現象（提供値 + 再現計測）
+- 平均スループット: 56.7M → 55.95M ops/s（-1.3% 誤差範囲）
+- L1-dcache-miss: 335M → 501M（+49.5%）
+- 当環境の `bench_random_mixed_hakmem 100000 256 42` でも L1 miss ≈ 3.7–4.0%（安定）

+   - 1バイトヘッダで user ptr を +1 するため、stride=サイズ+1 となり多くのクラスで16B整列を失う。
+   - 例: 256B→257B stride で 16ブロック中15ブロックが非整列。L1 miss/μops増の主因。

+   - コンパイラ最適化の悪影響やスピル増の可能性。
+
+対処（適用済み：UB除去の最小パッチ）
+- 追加: 安全 next アクセス小箱 `core/tiny_nextptr.h:1`
+  - `tiny_next_load()/tiny_next_store()` を memcpy ベースで提供（非整列でもUBなし）
+- 適用先（ホットパス）
+  - `core/hakmem_tiny_fastcache.inc.h:76,108`（tiny_fast_pop/push）
+  - `core/tiny_free_magazine.inc.h:83,94`（BG spill チェイン構築）
+
+効果（短期計測）
+- Throughput/L1 miss は誤差範囲で横ばい（正当性の改善が主、性能は現状維持）
+- 本質は「整列崩れ」→ 次の対策で A/B 確認へ
+
+未解決の懸念（要フォロー）
+- Release ガード漏れの可能性: `[C7_FIRST_FREE]`/`[DEBUG ss_remote_push]` が release でも1回だけ出力
+  - 該当箇所: `core/tiny_superslab_free.inc.h:36`, `core/superslab/superslab_inline.h:208`
+  - Makefile上は `-DHAKMEM_BUILD_RELEASE=1`（print-flags でも確認）。TUごとのCFLAGS齟齬を監査。
+
+次アクション（Tiny alignment 検証のA/B）
+1) ヘッダ全無効 A/B（即時）
+```
+# A: 現行（ヘッダON）
+./build.sh bench_random_mixed_hakmem
+perf stat -e cycles,instructions,branches,branch-misses,cache-references,cache-misses,\
+  L1-dcache-loads,L1-dcache-load-misses -r 5 -- ./bench_random_mixed_hakmem 100000 256 42
+
+# B: ヘッダOFF（クラス全体）
+EXTRA_MAKEFLAGS="HEADER_CLASSIDX=0" ./build.sh bench_random_mixed_hakmem
+perf stat -e cycles,instructions,branches,branch-misses,cache-references,cache-misses,\
+  L1-dcache-loads,L1-dcache-load-misses -r 5 -- ./bench_random_mixed_hakmem 100000 256 42
+```
+2) 固定サイズ 256B の比較（alignment 影響の顕在化狙い）
+```
+./build.sh bench_fixed_size_hakmem
+perf stat -e cycles,instructions,cache-references,cache-misses,L1-dcache-loads,L1-dcache-load-misses \
+  -r 5 -- ./bench_fixed_size_hakmem 100000 256 42
+```
+3) FastCache 稼働確認（C0–C3 ヒット率の見える化）
+```
+HAKMEM_TINY_FAST_STATS=1 ./bench_random_mixed_hakmem 100000 256 42
+```
+
+中期対策（Box設計の指針）
+- 方針A（簡易・高効果）: ヘッダを小クラス（C0–C3）限定に縮小、C4–C6は整列重視（ヘッダなし）。
+  - 実装: まず A/B でヘッダ全OFFの効果を確認→効果大なら「クラス限定ヘッダ」へ段階導入。
+- 方針B（高度）: フッタ方式やビットタグ化など“アラインメント維持”の識別方式へ移行。
+  - 例: 16B整列を保つパディング/タグで class_idx を保持（RSS/複雑性と要トレードオフ検証）。
+
+トラッキング（ファイル/行）
+- 安全 next 小箱: `core/tiny_nextptr.h:1`
+- 差し替え: `core/hakmem_tiny_fastcache.inc.h:76,108`, `core/tiny_free_magazine.inc.h:83,94`
+- 追加監査対象（未修正だが next を直接触る箇所）
+  - `core/tiny_alloc_fast_inline.h:54,297`, `core/hakmem_tiny_tls_list.h:63,76,109,115` ほか
+
+成功判定（Tiny）
+- A/B（ヘッダOFF）で 256B 固定の L1 miss 低下、ops/s 上昇（±20–50% を期待）
+- mimalloc との差が大幅に縮小（まず 2–3x → 継続改善で 1.5x 以内へ）
+
+最新A/Bスナップショット（当環境, RandomMixed 256B）
+- HEADER_CLASSIDX=1（現行）: 平均 ≈ 8.16M ops/s, L1D miss ≈ 3.79%
+- HEADER_CLASSIDX=0（全OFF）: 平均 ≈ 9.12M ops/s, L1D miss ≈ 3.74%
+- 差分: +11.7% 前後の改善（整列効果は小〜中。追加のチューニング継続）
