Documentation: - Created docs/DEFENSIVE_LAYERS_MAPPING.md documenting all 5 defensive layers - Maps which symptoms each layer suppresses - Defines safe removal order after root cause fix - Includes test methods for each layer removal Diagnostic Logging Enhancements (ChatGPT work): - TLS_SLL_HEAD_SET log with count and backtrace for NORMALIZE_USERPTR - tiny_next_store_log with filtering capability - Environment variables for log filtering: - HAKMEM_TINY_SLL_NEXTCLS: class filter for next store (-1 disables) - HAKMEM_TINY_SLL_NEXTTAG: tag filter (substring match) - HAKMEM_TINY_SLL_HEADCLS: class filter for head trace Current Investigation Status: - sh8bench 60/120s: crash-free, zero NEXT_INVALID/HDR_RESET/SANITIZE - BUT: shot limit (256) exhausted by class3 tls_push before class1/drain - Need: Add tags to pop/clear paths, or increase shot limit for class1 Purpose of this commit: - Document defensive layers for safe removal later - Enable targeted diagnostic logging - Prepare for final root cause identification Next Steps: 1. Add tags to tls_sll_pop tiny_next_write (e.g., "tls_pop_clear") 2. Re-run with HAKMEM_TINY_SLL_NEXTTAG=tls_pop 3. Capture class1 writes that lead to corruption 🤖 Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
