Comprehensive legacy cleanup and architecture consolidation Summary of Changes: MOVED TO ARCHIVE: - core/hakmem_tiny_legacy_slow_box.inc → archive/ * Slow path legacy code preserved for reference * Superseded by Gatekeeper Box architecture - core/superslab_allocate.c → archive/superslab_allocate_legacy.c * Legacy SuperSlab allocation implementation * Functionality integrated into new Box system - core/superslab_head.c → archive/superslab_head_legacy.c * Legacy slab head management * Refactored through Box architecture REMOVED DEAD CODE: - Eliminated unused allocation policy variants from ss_allocation_box.c * Reduced from 127+ lines of conditional logic to focused implementation * Removed: old policy branches, unused allocation strategies * Kept: current Box-based allocation path ADDED NEW INFRASTRUCTURE: - core/superslab_head_stub.c (41 lines) * Minimal stub for backward compatibility * Delegates to new architecture - Enhanced core/superslab_cache.c (75 lines added) * Added missing API functions for cache management * Proper interface for SuperSlab cache integration REFACTORED CORE SYSTEMS: - core/hakmem_super_registry.c * Moved registration logic from scattered locations * Centralized SuperSlab registry management - core/hakmem_tiny.c * Removed 27 lines of redundant initialization * Simplified through Box architecture - core/hakmem_tiny_alloc.inc * Streamlined allocation path to use Gatekeeper * Removed legacy decision logic - core/box/ss_allocation_box.c/h * Dramatically simplified allocation policy * Removed conditional branches for unused strategies * Focused on current Box-based approach BUILD SYSTEM: - Updated Makefile for archive structure - Removed obsolete object file references - Maintained build compatibility SAFETY & TESTING: - All deletions verified: no broken references - Build verification: RELEASE=0 and RELEASE=1 pass - Smoke tests: 100% pass rate - Functional verification: allocation/free intact Architecture Consolidation: Before: Multiple overlapping allocation paths with legacy code branches After: Single unified path through Gatekeeper Boxes with clear architecture Benefits: - Reduced code size and complexity - Improved maintainability - Single source of truth for allocation logic - Better diagnostic/observability hooks - Foundation for future optimizations 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

// Purpose: SuperSlab allocation/deallocation割り当ての出入口 Box
//
// Responsibilities:
// - Allocate SuperSlab with ACE-aware sizing
// - Free SuperSlab with LRU cache integration
