d54893ea1d Phase 3 C3: Static Routing A/B Test ADOPT (+2.20% Mixed gain) 
Step 2 & 3 Complete:
- A/B test (Mixed 10-run): STATIC_ROUTE=0 (38.91M) → =1 (39.77M) = +2.20% avg
  - Median gain: +1.98%
  - Result: ✅ GO (exceeds +1.0% threshold)

- Decision: ✅ ADOPT into MIXED_TINYV3_C7_SAFE preset
  - bench_profile.h line 77: HAKMEM_TINY_STATIC_ROUTE=1 default
  - Learner auto-disables static route when HAKMEM_SMALL_LEARNER_V7_ENABLED=1

Implementation Summary:
- core/box/tiny_static_route_box.{h,c}: Research box (Step 1A)
- core/front/malloc_tiny_fast.h: Route lookup integration (Step 1B, lines 249-256)
- core/bench_profile.h: Bench sync + preset adoption

Cumulative Phase 2-3 Gains:
- B3 (Routing shape): +2.89%
- B4 (Wrapper split): +1.47%
- C3 (Static routing): +2.20%
- Total: ~6.8% (35.2M → ~39.8M ops/s)

Next: Phase 3 C1 (TLS Prefetch, expected +2-4%)

212739607a Phase v11a-3: MID v3.5 Activation (Build Complete) 
Integrated MID v3.5 into active code path, making it available for C5/C6/C7 routing.

Key Changes:
- Policy Box: Added SMALL_ROUTE_MID_V35 with ENV gates (HAKMEM_MID_V35_ENABLED, HAKMEM_MID_V35_CLASSES)
- HotBox: Implemented small_mid_v35_alloc/free with TLS-cached page allocation
- Front Gate: Wired MID_V35 routing into malloc_tiny_fast.h (priority: ULTRA > MID_V35 > V7)
- Build: Added core/smallobject_mid_v35.o to all object lists

Architecture:
- Slot sizes: C5=384B, C6=512B, C7=1024B
- Page size: 64KB (170/128/64 slots)
- Integration: ColdIface v2 (refill/retire), Stats v2 (observation), Learner v2 (dormant)

Status: Build successful, ready for A/B benchmarking
Next: Performance validation (C6-heavy, C5+C6-only, Mixed benchmarks)

540230c301 v7-7: Modularize Learner into separate box 
Refactoring: Separate Learner API and types from Policy Box
- New: core/box/smallobject_learner_v7_box.h
  - SmallLearnerStatsV7 type definition
  - Learner recording API (record_refill, record_retire)
  - Learner evaluation and stats snapshot
  - Learner configuration constants
- Updated: core/box/smallobject_policy_v7_box.h
  - Removed Learner API (moved to Learner Box)
  - Removed SmallLearnerStatsV7 type (moved to Learner Box)
  - Added include of smallobject_learner_v7_box.h
  - Kept small_policy_v7_update_from_learner() (L3 integration)
- Updated: core/smallobject_policy_v7.c
  - Added include of smallobject_learner_v7_box.h

Benefits:
- Clearer module boundaries (Policy vs Learner)
- Easier testing and debugging (stats isolation)
- Reduced coupling between components

Performance: No regression (v7+Learner: 41M ops/s on C5/C6)

6f559e1a1d v7-7: Implement Learner for dynamic C5 route switching 
- Add SmallLearnerStatsV7 type + API to policy box
- Hook ColdIface refill/retire to collect stats (capacity-based)
- Implement C5 route switching: if C5 ratio < 30%, switch to MID_V3
- Version-based TLS cache invalidation for policy updates
- Evaluation interval: every 100 refills

Tested with c6heavy scenario: C5 ratio=12% triggers V7 → MID_V3 switch

8143e8b797 Phase v7-4: Policy Box 導入 (L3 層の明確化とフロント芯の作り直し) 
- SmallPolicyV7 Box: L3 Policy layer に配置、route 決定を一元化
- Route kind enum: SMALL_ROUTE_ULTRA / V7 / MID_V3 / LEGACY
- ENV priority (fixed): ULTRA > v7 > MID_v3 > LEGACY
- Frontend integration: v7 routing を Policy Box 経由に変更 (段階移行)
- Legacy compatibility: 既存の tiny_route_env_box.h は併用維持

Box Theory layer structure:
- L0: ULTRA (C4-C7, FROZEN)
- L1: SmallObject v7 (research box)
- L1': MID_v3 / LEGACY (fallback)
- L2: Segment / RegionId
- L3: Policy / Stats / Learner ← Policy Box added here

Frontend now follows clean "size→class→route_kind→switch" pattern.
ENV variables read once at Policy init, not scattered across frontend.

Future: ULTRA/MID_v3/LEGACY consolidation, Learner integration, flexible priority.
