Phase12 debug: restore SUPERSLAB constants/APIs, implement Box2 drain boundary, fix tiny_fast_pop to return BASE, honor TLS SLL toggle in alloc/free fast paths, add fail-fast stubs, and quiet capacity sentinel. Update CURRENT_TASK with A/B results (SLL-off stable; SLL-on crash).

Cleanup: Consolidate debug ENV vars to HAKMEM_DEBUG_LEVEL Integrated 4 new debug environment variables added during bug fixes into the existing unified HAKMEM_DEBUG_LEVEL system (expanded to 0-5 levels). Changes: 1. Expanded HAKMEM_DEBUG_LEVEL from 0-3 to 0-5 levels: - 0 = OFF (production) - 1 = ERROR (critical errors) - 2 = WARN (warnings) - 3 = INFO (allocation paths, header validation, stats) - 4 = DEBUG (guard instrumentation, failfast) - 5 = TRACE (verbose tracing) 2. Integrated 4 environment variables: - HAKMEM_ALLOC_PATH_TRACE → HAKMEM_DEBUG_LEVEL >= 3 (INFO) - HAKMEM_TINY_SLL_VALIDATE_HDR → HAKMEM_DEBUG_LEVEL >= 3 (INFO) - HAKMEM_TINY_REFILL_FAILFAST → HAKMEM_DEBUG_LEVEL >= 4 (DEBUG) - HAKMEM_TINY_GUARD → HAKMEM_DEBUG_LEVEL >= 4 (DEBUG) 3. Kept 2 special-purpose variables (fine-grained control): - HAKMEM_TINY_GUARD_CLASS (target class for guard) - HAKMEM_TINY_GUARD_MAX (max guard events) 4. Backward compatibility: - Legacy ENV vars still work via hak_debug_check_level() - New code uses unified system - No behavior changes for existing users Updated files: - core/hakmem_debug_master.h (level 0-5 expansion) - core/hakmem_tiny_superslab_internal.h (alloc path trace) - core/box/tls_sll_box.h (header validation) - core/tiny_failfast.c (failfast level) - core/tiny_refill_opt.h (failfast guard) - core/hakmem_tiny_ace_guard_box.inc (guard enable) - core/hakmem_tiny.c (include hakmem_debug_master.h) Impact: - Simpler debug control: HAKMEM_DEBUG_LEVEL=3 instead of 4 separate ENVs - Easier to discover/use - Consistent debug levels across codebase - Reduces ENV variable proliferation (43+ vars surveyed) Future work: - Consolidate remaining 39+ debug variables (documented in survey) - Gradual migration over 2-3 releases 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
