# 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

### 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"
```
