- [ ] Run linting: `podman compose up test-lint`
- [ ] Check for hardcoded secrets
- [ ] Verify error handling completeness
- [ ] Review input validation
- [ ] Check for SQL injection/code injection

### 3. **Profitability & Trading Logic** 💰
Files to audit:

- `cmd/mev-bot/main.go` - Main bot entry point

Key checks:
- [ ] Threshold configuration (0.1% minimum)
- [ ] Profit calculation accuracy
- [ ] Gas estimation correctness
- [ ] Slippage handling
- [ ] Flash loan integration
- [ ] Multi-hop detection
- [ ] Price impact calculations

### 4. **Integration & Production Config** ⚙️
- [ ] RPC endpoint configuration
- [ ] Rate limiting settings
- [ ] Connection pooling
- [ ] Error recovery mechanisms
- [ ] Health checks
- [ ] Logging completeness
- [ ] Monitoring setup

### 5. **Make Commands Optimization** 🔨
- [ ] Verify all `make` commands work
- [ ] Check Podman integration in all CI/CD targets
- [ ] Ensure caching is optimized
- [ ] Test incremental builds

### 6. **Dockerfile & Container Optimization** 📦
- [ ] Multi-stage build efficiency
- [ ] Layer caching optimization
- [ ] Image size optimization
- [ ] Security: non-root user
- [ ] Base image selection

## Audit Checklist

### Phase 1: Testing (Current)
```bash
# Run all test suites
podman compose -f docker-compose.test.yml up test-unit
podman compose -f docker-compose.test.yml up test-coverage
podman compose -f docker-compose.test.yml up test-security
podman compose -f docker-compose.test.yml up test-lint

# Generate reports
make test-coverage
make audit-full
```

### Phase 2: Code Review
- [ ] Review trading logic for correctness
- [ ] Verify mathematical precision (no floating point errors)
- [ ] Check edge case handling
- [ ] Validate RPC error handling
- [ ] Review goroutine management
- [ ] Check memory leaks potential

### Phase 3: Integration Testing
- [ ] Test with mock RPC endpoints
- [ ] Verify transaction building
- [ ] Test error scenarios
- [ ] Validate recovery mechanisms
- [ ] Check connection stability

### Phase 4: Performance Testing
- [ ] Measure transaction processing latency
- [ ] Check memory usage under load
- [ ] Verify CPU usage
- [ ] Test concurrent request handling
- [ ] Measure opportunity detection speed

## Critical Issues to Investigate

### 1. **Test Failures**
- Current: Status unknown (tests running)
- Action: Analyze and fix all failures

### 2. **Code Coverage**
- Target: 100%
- Current: Unknown
- Action: Identify and test uncovered paths

### 3. **Trading Logic Issues**
Key concerns:
- Is opportunity detection working?
- Are we correctly calculating profits?
- Are gas costs properly estimated?
- Is slippage being handled?
- Are flash loans integrated?

### 4. **Production Configuration**
- RPC rate limiting
- Connection pooling
- Error recovery
- Health checks
- Monitoring

### 5. **Make Commands**
Verify these work with Podman:
- `make build` ✅
- `make test` ⏳
- `make test-coverage` ⏳
- `make ci-container` ⏳
- `make audit-full` ⏳

## Remediation Plan (If Issues Found)

### For Failing Tests:
1. Analyze failure root cause
2. Create minimal test case
3. Fix underlying code issue
4. Add regression test
5. Verify fix passes all related tests

### For Coverage Gaps:
1. Identify uncovered code paths
2. Create test case for path
3. Add edge case tests
4. Verify coverage increases to 100%

### For Trading Logic Issues:
1. Review algorithm correctness
2. Add unit tests for calculations
3. Add integration tests with mock data
4. Validate against expected outputs
5. Test edge cases (zero amounts, extreme prices, etc.)

### For Production Config Issues:
1. Review configuration files
2. Add validation logic
3. Create integration tests
4. Document all settings
5. Create example configs
