## 🎯 Next Steps
### Phase 3: SuperSlab Registry Debug Variables (Pending)
Target file: `core/hakmem_super_registry.c/.h`
**ENV Variables Identified** (8 vars):
- `HAKMEM_SUPER_LOOKUP_DEBUG` (header inline function)
- `HAKMEM_SUPER_REG_DEBUG` (register/unregister debug)
- `HAKMEM_SS_LRU_DEBUG` (3 call sites: evict_one, lru_pop, lru_push)
- `HAKMEM_SUPERSLAB_MAX_CACHED` (LRU configuration)
- `HAKMEM_SUPERSLAB_MAX_MEMORY_MB` (LRU configuration)
- `HAKMEM_SUPERSLAB_TTL_SEC` (LRU configuration)
- `HAKMEM_SS_PREWARM_DEBUG` (prewarm logging)
- `HAKMEM_PREWARM_SUPERSLABS` (prewarm count)
**Estimated Impact**: 8 variables, higher complexity (LRU + prewarm logic)
**Risk Level**: Medium (touches hot path SuperSlab registry)
### Phase 4: Medium-Risk Variables (Pending)
- `core/front/tiny_heap_v2.h` - HeapV2 feature flags
- `core/page_arena.h` - Page arena configuration
