Moe Charm (CI)	a948332f6c	Update REFACTOR_PLAN_GEMINI_ENHANCED.md with Gemini final findings ... Status Updates (2025-12-03): - Phase 0.1-0.2: ✅ Already implemented (ptr_type_box.h, ptr_conversion_box.h) - Phase 0.3: ✅ VERIFIED - Gemini mathematically proved sh8bench adds +1 to odd returns - Phase 2: 🔄 RECONSIDERED - Headerless layout is legitimate long-term goal - Phase 3.1: Current NORMALIZE + log is correct fail-safe behavior Root Cause Analysis: - Issue A (Fixed): Header restoration gaps at Box boundaries (4 commits) - Issue B (Root): hakmem returns odd addresses, violating C standard alignment Gemini's Proof: - Log analysis: node=0xe1 → user_ptr=0xe2 = +1 delta - ASan doesn't reproduce because Redzone ensures alignment - Conclusion: sh8bench expects alignof(max_align_t), hakmem violates it Recommendations: - Short-term: Current defensive measures (Atomic Fence + Header Write) sufficient - Long-term: Phase 2 (Headerless Layout) for C standard compliance 🤖 Generated with Claude Code Co-Authored-By: Gemini <gemini@example.com> Co-Authored-By: Claude <noreply@anthropic.com>	2025-12-03 11:20:18 +09:00
