- tiny_route_env_box.h: TINY_ROUTE_SMALL_HEAP_V5 enum 追加、route snapshot で C6→v5 分岐 - malloc_tiny_fast.h: alloc/free switch に v5 case 追加（v1/pool fallback） - smallobject_hotbox_v5.c: stub 実装（alloc は NULL 返却、free は no-op） - smallobject_hotbox_v5_box.h: 関数 signature に ctx パラメータ追加 - Makefile: core/smallobject_hotbox_v5.o をリンクリストに追加 - ENV_PROFILE_PRESETS.md: v5-1 プリセット追記 - CURRENT_TASK.md: Phase v5-1 完了記録 **特性**: - ENV: HAKMEM_SMALL_HEAP_V5_ENABLED=1 / HAKMEM_SMALL_HEAP_V5_CLASSES=0x40 で opt-in - テスト結果: C6-heavy (v5 OFF 15.5M → v5 ON 16.4M ops/s, 正常), Mixed 47.2M ops/s, SEGV/assert なし - 挙動は v1/pool fallback と同じ（実装は v5-2） 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
