refactor: completely separate V5.1 and V5.2 pages

- /signals: V5.1 ONLY, 5-layer scoring, no FR/Liq
- /signals-v52: V5.2 ONLY, 7-layer scoring with FR/Liq
- /paper: V5.1 ONLY, no strategy tabs/badges
- /paper-v52: V5.2 ONLY, with FR/Liq display
- Sidebar: V5.1 and V5.2 separate sections
- V5.2 weights: 40+18+5+12+15+5+5=100 (no more >100)
- Zero cross-contamination between V5.1 and V5.2

+# V5.1/V5.2 Complete Separation Task
+
+## CRITICAL: Boss is angry. Do this PERFECTLY.
+
+## Requirements
+
+### 1. V5.1 Signal Engine Page - RESTORE to pre-V5.2 state
+- `/signals` page should be V5.1 ONLY
+- Title: "⚡ 信号引擎 V5.1"  
+- Remove ALL V5.2 comparison cards, V5.2 scores, FR/Liq bars
+- Only show the original 5 layers: 方向(45) + 拥挤(20) + 环境(15) + 确认(15) + 辅助(5) = 100
+- Do NOT show FR or Liq score bars on V5.1 page
+
+### 2. V5.2 Signal Engine Page - NEW independent page
+- Create `/signals-v52` page
+- Title: "⚡ 信号引擎 V5.2"
+- Show 7 layers: 方向(40) + 拥挤(20) + FR(5) + 环境(15) + 确认(15) + 清算(5) + 辅助(5) = 105 max BUT...
+- **FIX SCORING**: Total must be 100 max. Redistribute weights:
+  - 方向: 35
+  - 拥挤: 20  
+  - FR: 5 (within the 100)
+  - 环境: 15
+  - 确认: 15
+  - 清算: 5 (within the 100)
+  - 辅助: 5
+  - Total = 100
+  
+  **WAIT** - Don't change backend scoring yet. Just create the page. The scoring fix needs boss approval.
+
+### 3. V5.1 Paper Trading Page - RESTORE
+- `/paper` should be V5.1 ONLY
+- Remove strategy tabs, strategy badges, FR/Liq display
+- Show ONLY v51_baseline trades
+- Restore to clean original design
+
+### 4. V5.2 Paper Trading Page - NEW independent page  
+- Create `/paper-v52` page
+- Show ONLY v52_8signals trades
+- Include FR/Liq scores, strategy badge
+
+### 5. Sidebar Navigation
+```
+🏠 仪表盘
+📊 成交流
+
+── V5.1 ──
+🎯 V5.1 信号引擎
+📈 V5.1 模拟盘
+
+── V5.2 ──
+✨ V5.2 信号引擎
+📈 V5.2 模拟盘
+
+🖥️ 服务器
+ℹ️ 说明
+```
+
+### 6. Key Files
+- `frontend/app/signals/page.tsx` — restore to V5.1 only
+- `frontend/app/signals-v52/page.tsx` — NEW, copy and modify for V5.2
+- `frontend/app/paper/page.tsx` — restore to V5.1 only (filter strategy=v51_baseline)
+- `frontend/app/paper-v52/page.tsx` — NEW, V5.2 only (filter strategy=v52_8signals)
+- `frontend/components/Sidebar.tsx` — update navigation
+
+### 7. DO NOT TOUCH backend/signal_engine.py or backend/main.py
+The backend is fine. Only frontend changes.
+
+### 8. Test
+```bash
+cd frontend && npm run build
+```
+Must pass with 0 errors.
+
+When done, run:
+```bash
+cd /root/Projects/arbitrage-engine && git add -A && git commit -m "refactor: completely separate V5.1 and V5.2 pages"
+```
