- 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. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

// smallobject_policy_v7_box.h - SmallObject Policy v7 (Phase v7-4)

//
|
|
// Purpose:
|
|
// - Centralized routing policy for ULTRA / v7 / MID_v3 / LEGACY
|
|
// - Single source of truth for class → route_kind mapping
|
|
// - ENV configuration managed in one place (L3 Policy layer)
