Updated project guidance to reflect V2 foundation completion:

Branch Structure:
- v2-master (production, protected)
- v2-master-dev (development, protected)
- feature/v2-prep (archived, foundation complete)
- feature/v2/* (feature branches from v2-master-dev)

Branch Hierarchy:
v2-master ← v2-master-dev ← feature/v2/*

Updated Sections:
- Project Status: V2 Foundation Complete 
- Git Workflow: New branch structure and workflow
- Example Workflow: Updated to use v2-master-dev
- What TO Do: Reflects foundation completion
- Key Files: Added V2 foundation files (100% coverage)
- Current Branches: New section documenting branch structure
- Contact and Resources: Updated with completion status

Workflow:
1. Create feature branch from v2-master-dev
2. Implement with 100% test coverage
3. Run make validate locally
4. PR to v2-master-dev (CI/CD enforces coverage)
5. Merge v2-master-dev → v2-master for production

Foundation Status:
- 3,300+ lines (1,500 implementation, 1,800 tests)
- 100% test coverage (enforced)
- CI/CD fully configured
- Ready for protocol parser implementations

## 🚀 Next Phase: Protocol Parsers
### Phase 2: Parser Implementations (45 hours estimated)
The foundation is complete and ready for protocol-specific parsers:
**UniswapV2 Parser (P2-002 through P2-009)**
- ParseLog() for Swap events
- Token extraction from pool cache
- Validation rules
- Mint/Burn event support
- ParseReceipt() for multi-event handling
- Comprehensive unit tests
- Integration tests with real Arbiscan data
**UniswapV3 Parser (P2-010 through P2-017)**
- Signed amount handling (int256)
- SqrtPriceX96 decoding
- Tick and liquidity tracking
- Fee tier support
- Concentrated liquidity calculations
**Additional Protocols:**
- Curve StableSwap (P2-018 through P2-024)
- Balancer V2 (P2-025 through P2-031)
- Kyber Classic/Elastic (P2-032 through P2-038)
- Camelot V2 (P2-039 through P2-045)
- Camelot V3 variants (P2-046 through P2-055)
### Implementation Pattern
Each parser follows the same pattern established by the factory:
```go
// 1. Implement Parser interface
type UniswapV2Parser struct {
logger Logger
cache PoolCache
}
// 2. Implement required methods
func (p *UniswapV2Parser) ParseLog(ctx context.Context, log types.Log, tx *types.Transaction) (*types.SwapEvent, error)
func (p *UniswapV2Parser) ParseReceipt(ctx context.Context, receipt *types.Receipt, tx *types.Transaction) ([]*types.SwapEvent, error)
func (p *UniswapV2Parser) SupportsLog(log types.Log) bool
func (p *UniswapV2Parser) Protocol() types.ProtocolType
// 3. Register with factory
factory.RegisterParser(types.ProtocolUniswapV2, parser)
// 4. Write comprehensive tests (100% coverage)
```

## 🎯 Performance Targets
### Latency Targets (from Profitability Plan)
```
Sequencer to Parse: < 5ms ✅ Infrastructure ready
Parse to Validate: < 2ms ✅ Validation ready
Validate to Detect: < 10ms ⏳ Pending arbitrage detection
Detect to Execute: < 30ms ⏳ Pending execution engine
Total (End-to-End): < 50ms ⏳ Pending full integration
```
### Profitability Targets
```
Success rate: > 85%
Min profit per trade: > 0.05 ETH (after gas)
Daily trades: 50-200
Monthly ROI: > 20%
```
### Conservative Projections (from 04_PROFITABILITY_PLAN.md)
```
Daily: 0.6 ETH profit
Monthly: 18 ETH profit
Yearly: 216 ETH profit
With 10 ETH capital deployed:
Monthly ROI: 180%
Yearly ROI: 2160%
```
---
## 🧪 Testing Philosophy
### Test-Driven Development (TDD)
All components follow strict TDD:
1. **Write tests first** - Define expected behavior
2. **Implement functionality** - Make tests pass
3. **Refactor** - Improve while keeping tests green
4. **Coverage validation** - Ensure 100% coverage
### Test Types
**Unit Tests** - Every function tested independently
- Mock dependencies
- Test all code paths
- Edge cases and boundaries
- Error conditions
**Integration Tests** - Components working together
- Real dependencies where appropriate
- End-to-end scenarios
- Performance validation
**Decimal Precision Tests** - Critical for MEV
- Exact decimal handling
- Rounding error detection
- Cross-decimal conversions (USDC 6, WBTC 8, WETH 18)
**Concurrency Tests** - Thread safety
- Race detection enabled
- Concurrent access patterns
- Deadlock prevention
