Refactor: Extract 4 safe Box modules from hakmem_tiny.c (-73% total reduction)
Conservative refactoring with Task-sensei's safety analysis.
## Changes
**hakmem_tiny.c**: 616 → 562 lines (-54 lines, -9% this phase)
**Total reduction**: 2081 → 562 lines (-1519 lines, -73% cumulative) 🏆
## Extracted Modules (4 new LOW-risk boxes)
9. **ss_active_box** (6 lines)
- ss_active_add() - atomic add to active counter
- ss_active_inc() - atomic increment active counter
- Pure utility functions, no dependencies
- Risk: LOW
10. **eventq_box** (32 lines)
- hak_thread_id16() - thread ID compression
- eventq_push_ex() - event queue push with sampling
- Intelligence/telemetry helpers
- Risk: LOW
11. **sll_cap_box** (12 lines)
- sll_cap_for_class() - SLL capacity policy
- Hot classes get multiplier × mag_cap
- Cold classes get mag_cap / 2
- Risk: LOW
12. **ultra_batch_box** (20 lines)
- g_ultra_batch_override[] - batch size overrides
- g_ultra_sll_cap_override[] - SLL capacity overrides
- ultra_batch_for_class() - batch size policy
- Risk: LOW
## Cumulative Progress (12 boxes total)
**Phase 1** (5 boxes): 2081 → 995 lines (-52%)
**Phase 2** (3 boxes): 995 → 616 lines (-38%)
**Phase 3** (4 boxes): 616 → 562 lines (-9%)
**All 12 boxes**:
1. config_box (211 lines)
2. publish_box (419 lines)
3. globals_box (256 lines)
4. phase6_wrappers_box (122 lines)
5. ace_guard_box (100 lines)
6. tls_state_box (224 lines)
7. legacy_slow_box (96 lines)
8. slab_lookup_box (77 lines)
9. ss_active_box (6 lines) ✨
10. eventq_box (32 lines) ✨
11. sll_cap_box (12 lines) ✨
12. ultra_batch_box (20 lines) ✨
**Total extracted**: 1,575 lines across 12 coherent modules
**Remaining core**: 562 lines (highly focused)
## Safety Approach
- Task-sensei performed deep dependency analysis
- Extracted only LOW-risk candidates
- All dependencies verified at compile time
- Forward declarations already present
- No circular dependencies
- Build tested after each extraction ✅
