# 🚀 MEV Bot Production Guide for Qwen Code

## Critical Production Status: Build Fixes Required

**⚠️ IMMEDIATE ACTION REQUIRED**: The MEV bot currently has build errors that must be resolved before production deployment. Qwen Code must address these fundamental type conflicts first.

### Current Build Issues Summary
```bash
# Primary Issues:
1. Protocol type conflicts between packages (arbcommon.Protocol vs local Protocol)
2. Interface mismatches in DEXParserInterface implementations
3. Missing type conversions in pool cache operations
4. Parser factory type incompatibilities
```

---

## 🎯 QWEN CODE PRODUCTION MANDATE

### Phase 1: CRITICAL BUILD RESOLUTION (IMMEDIATE)

**Tasks for Qwen Code:**

1. **Protocol Type Unification**
   ```bash
   # Action: Standardize on arbcommon.Protocol across ALL packages
   # Files to fix:
   - pkg/arbitrum/enhanced_types.go (remove duplicate Protocol type)
   - pkg/arbitrum/pool_cache.go (fix AddPoolIfNotExists signature)
   - pkg/arbitrum/protocol_parsers.go (fix all parser returns)
   ```

2. **Interface Consistency**
   ```bash
   # Action: Ensure all DEXParserInterface implementations return same types
   # Fix: pkg/arbitrum/parsers/* - align all return types with arbcommon.EnhancedDEXEvent
   ```

3. **Import Standardization**
   ```bash
   # Action: Add arbcommon import alias to ALL arbitrum package files
   # Pattern: arbcommon "github.com/fraktal/mev-beta/pkg/arbitrum/common"
   ```

## 🔧 IMMEDIATE QWEN CODE ACTIONS

### Step 1: Fix Build (URGENT - Do First)
```bash
# Run these commands to identify exact conflicts:
go build -v ./... 2>&1 | grep "cannot use"
go build -v ./... 2>&1 | grep "mismatched types"

# Priority fixes:
1. Remove duplicate Protocol type from enhanced_types.go
2. Update all parsers to return arbcommon.EnhancedDEXEvent
3. Fix pool_cache.go AddPoolIfNotExists signature
4. Standardize all Protocol type references
```

### Step 2: Security Audit (Do Second)
```bash
# Security scan commands:
gosec ./...
go list -json -m all | nancy sleuth
git-secrets --scan
semgrep --config=auto .
```

### Step 3: Performance Testing (Do Third)
```bash
# Benchmark commands:
go test -bench=. -benchmem ./...
go tool pprof http://localhost:6060/debug/pprof/profile
ab -n 1000 -c 10 http://localhost:8080/health
```
