Phase 21-1-B: Ring cache Alloc/Free 統合 - C2/C3 hot path integration **統合内容**: - Alloc path (tiny_alloc_fast.inc.h): Ring pop → HeapV2/UltraHot/SLL fallback - Free path (tiny_free_fast_v2.inc.h): Ring push → HeapV2/SLL fallback - Lazy init: 最初の alloc/free 時に自動初期化（thread-safe） **設計**: - Lazy init パターン（ENV control と同様） - ring_cache_pop/push 内で slots == NULL チェック → ring_cache_init() 呼び出し - Include 構造: ファイルトップレベルに #include 追加（関数内 include 禁止） **Makefile 修正**: - TINY_BENCH_OBJS_BASE に core/front/tiny_ring_cache.o 追加 - Link エラー修正: 4箇所の object list に追加 **動作確認**: - Ring OFF (default): 83K ops/s (1K iterations) ✅ - Ring ON (HAKMEM_TINY_HOT_RING_ENABLE=1): 78K ops/s ✅ - クラッシュなし、正常動作確認 **次のステップ**: Phase 21-1-C (Refill/Cascade 実装)

feat: Add ACE allocation failure tracing and debug hooks This commit introduces a comprehensive tracing mechanism for allocation failures within the Adaptive Cache Engine (ACE) component. This feature allows for precise identification of the root cause for Out-Of-Memory (OOM) issues related to ACE allocations. Key changes include: - **ACE Tracing Implementation**: - Added environment variable to enable/disable detailed logging of allocation failures. - Instrumented , , and to distinguish between "Threshold" (size class mismatch), "Exhaustion" (pool depletion), and "MapFail" (OS memory allocation failure). - **Build System Fixes**: - Corrected to ensure is properly linked into , resolving an error. - **LD_PRELOAD Wrapper Adjustments**: - Investigated and understood the wrapper's behavior under , particularly its interaction with and checks. - Enabled debugging flags for environment to prevent unintended fallbacks to 's for non-tiny allocations, allowing comprehensive testing of the allocator. - **Debugging & Verification**: - Introduced temporary verbose logging to pinpoint execution flow issues within interception and routing. These temporary logs have been removed. - Created to facilitate testing of the tracing features. This feature will significantly aid in diagnosing and resolving allocation-related OOM issues in by providing clear insights into the failure pathways.
