docs: update V2 implementation status with Phase 2 & 3 complete

Updated comprehensive status document to reflect completion of:
- Phase 1: Foundation (types, cache, observability)
- Phase 2: Protocol Parsers (UniswapV2, UniswapV3, Curve)
- Phase 3: Arbitrage Detection Engine (path finding, profitability, gas estimation)

Key Updates:
- Added detailed Phase 2 parser descriptions
- Added complete Phase 3 arbitrage detection overview
- Updated code statistics (13,447 lines across 38 files)
- Updated test coverage report (100% across all phases)
- Revised next steps to focus on Phase 4 (Execution Engine)
- Updated progress summary and conclusion

Statistics:
- Total Code: 13,447 lines
- Production: 7,051 lines
- Tests: 6,396 lines
- Files: 38
- Coverage: 100%

Next Phase: Execution Engine with flashloans, transaction building, and risk management.

+# Git Hooks for MEV Bot V2
+
+This directory contains Git hooks to ensure code quality and consistency.
+
+## Installation
+
+Run these commands from the repository root:
+
+```bash
+# Make hooks executable
+chmod +x .git-hooks/*
+
+# Install pre-commit hook
+ln -sf ../../.git-hooks/pre-commit .git/hooks/pre-commit
+
+# Install commit-msg hook
+ln -sf ../../.git-hooks/commit-msg .git/hooks/commit-msg
+```
+
+Or use the provided installation script:
+
+```bash
+./scripts/install-git-hooks.sh
+```
+
+## Available Hooks
+
+### pre-commit
+
+Runs before each commit and performs:
+
+1. **Branch Name Validation** - Ensures correct naming convention
+2. **Merge Conflict Detection** - Prevents committing conflict markers
+3. **Secret Detection** - Scans for passwords, API keys, tokens
+4. **Dependency Management** - Auto-tidies go.mod and go.sum
+5. **Code Formatting** - Auto-formats Go code with gofmt
+6. **Quick Tests** - Runs tests on changed packages
+7. **Go Vet** - Runs static analysis
+8. **File Size Check** - Warns about large files
+
+### commit-msg
+
+Validates commit message format:
+
+**Required Format:**
+```
+type(scope): description
+
+Optional body explaining the change
+
+🤖 Generated with [Claude Code](https://claude.com/claude-code)
+Co-Authored-By: Claude <noreply@anthropic.com>
+```
+
+**Valid Types:**
+- `feat` - New feature
+- `fix` - Bug fix
+- `perf` - Performance improvement
+- `refactor` - Code refactoring
+- `test` - Tests
+- `docs` - Documentation
+- `build` - Build system
+- `ci` - CI/CD
+
+**Example:**
+```
+feat(parsers): add UniswapV2 parser with event validation
+
+- Implements ParseLog() for Swap events
+- Adds token extraction from pool cache
+- Includes comprehensive validation rules
+- Achieves 100% test coverage

+
+## Bypassing Hooks (Emergency Only)
+
+If you absolutely must bypass hooks:
+
+```bash
+git commit --no-verify -m "emergency fix"
+```
+
+**⚠️ Warning:** Only use in emergencies. CI/CD will still enforce all checks.
+
+## Troubleshooting
+
+### Hook not executing
+
+1. Check if hook is executable:
+   ```bash
+   ls -l .git/hooks/pre-commit
+   ```
+
+2. If not, make it executable:
+   ```bash
+   chmod +x .git/hooks/pre-commit
+   ```
+
+### Hook failing unexpectedly
+
+1. Run the hook manually to see errors:
+   ```bash
+   .git/hooks/pre-commit
+   ```
+
+2. Check that all required tools are installed:
+   ```bash
+   which gofmt
+   which go
+   ```
+
+### Disabling hooks temporarily
+
+```bash
+# Disable all hooks
+git config core.hooksPath /dev/null
+
+# Re-enable hooks
+git config --unset core.hooksPath
+```
+
+## Best Practices
+
+1. **Never bypass hooks** unless absolutely necessary
+2. **Fix issues** instead of bypassing
+3. **Keep hooks fast** - they run on every commit
+4. **Test hooks locally** before committing to shared repository
+5. **Document any new hooks** added to this directory
+
+## Performance
+
+Hooks are designed to be fast:
+
+- **Pre-commit**: Typically < 5 seconds
+- **Commit-msg**: < 1 second
+
+If hooks are slow, consider:
+
+1. Only testing changed packages (already implemented)
+2. Using `--short` flag for tests (already implemented)
+3. Running full tests in CI/CD instead
+
+## Maintenance
+
+Review and update hooks periodically:
+
+1. Add new checks as project evolves
+2. Remove obsolete checks
+3. Optimize performance
+4. Keep documentation up to date

+## V1 Reference (orig/)
+
+### Building and Running V1
 ```bash
-# Build the MEV bot binary
+cd orig/
+go build -o ../bin/mev-bot-v1 ./cmd/mev-bot/main.go
+../bin/mev-bot-v1 start
+```
+
+### V1 Architecture Overview
+- **Monolithic parser**: Single parser handling all DEX types
+- **Basic validation**: Limited validation of parsed data
+- **Single-index cache**: Pool cache by address only
+- **Event-driven**: Real-time Arbitrum sequencer monitoring
+
+### Critical V1 Issues (driving V2 refactor)
+1. **Zero address tokens**: Parser returns zero addresses when transaction calldata unavailable
+2. **Parsing accuracy**: Generic parser misses protocol-specific edge cases
+3. **No validation audit trail**: Silent failures, no discrepancy logging
+4. **Inefficient lookups**: Single-index cache, no liquidity ranking
+5. **Stats disconnection**: Events detected but not reflected in metrics
+
+See `orig/README_V1.md` for complete V1 documentation.
+
+## V2 Architecture Plan
+
+### Key Improvements
+1. **Per-exchange parsers**: Individual parsers for UniswapV2, UniswapV3, SushiSwap, Camelot, Curve
+2. **Multi-layer validation**: Strict validation at parser, monitor, and scanner layers
+3. **Multi-index cache**: Lookups by address, token pair, protocol, and liquidity
+4. **Background validation**: Audit trail comparing parsed vs cached data
+5. **Observable by default**: Comprehensive metrics, structured logging, health monitoring
+
+### V2 Directory Structure (planned)

 ```
 
-### Production Log Management Commands
+### V2 Development (when started)
+
+**DO NOT** start V2 implementation without:
+1. Reviewing `docs/planning/00_V2_MASTER_PLAN.md`
+2. Reviewing `docs/planning/07_TASK_BREAKDOWN.md`
+3. Creating task branch from `feature/v2-prep`
+4. Following atomic task breakdown
+
+## Key Principles for V2 Development
+
+### 1. Fail-Fast with Visibility
+- Reject invalid data immediately at source
+- Log all rejections with detailed context
+- Never allow garbage data to propagate downstream
+
+### 2. Single Responsibility
+- One parser per exchange type
+- One validator per data type
+- One cache per index type
+
+### 3. Observable by Default
+- Every component emits metrics
+- Every operation is logged with context
+- Every error includes stack trace and state
+
+### 4. Test-Driven
+- Unit tests for every parser (>90% coverage)
+- Integration tests for full pipeline
+- Chaos testing for failure scenarios
+
+### 5. Atomic Tasks
+- Each task < 2 hours (from 07_TASK_BREAKDOWN.md)
+- Clear dependencies between tasks
+- Testable success criteria
+
+## Architecture Patterns Used
+
+### V1 (orig/)
+- **Monolithic parser**: Single `EventParser` handling all protocols
+- **Pipeline pattern**: Multi-stage processing with worker pools
+- **Event-driven**: WebSocket subscription to Arbitrum sequencer
+- **Connection pooling**: RPC connection management with failover
+
+### V2 (planned)
+- **Factory pattern**: Parser factory routes to protocol-specific parsers
+- **Strategy pattern**: Per-exchange parsing strategies
+- **Observer pattern**: Background validation observes all parsed events
+- **Multi-index pattern**: Multiple indexes over same pool data
+- **Circuit breaker**: Automatic failover on cascading failures
+

-- Implement proper error handling and recovery mechanisms
-- Adhere to the production-ready architecture patterns defined in PROJECT_SPECIFICATION.md
+```
+v2-master         # Production branch for V2 (protected)
+v2-master-dev     # Development branch for V2 (protected)
+feature/v2-prep   # Planning and foundation (archived)
+feature/v2/*      # Feature branches for development
+```
 
-## 📋 Development Guidelines & Code Style
+**Branch Hierarchy:**
+```
+v2-master (production)
+  ↑
+  └── v2-master-dev (development)
+        ↑
+        └── feature/v2/* (feature branches)
+```
 
-### Go Best Practices
-- **Error Handling**: Always wrap errors with context using `fmt.Errorf("operation failed: %w", err)`
-- **Concurrency**: Use worker pools for processing large datasets (see `pkg/market/pipeline.go`)
-- **Interfaces**: Keep interfaces small and focused (1-3 methods maximum)
-- **Testing**: Aim for >90% test coverage with table-driven tests
-- **Logging**: Use structured logging with `slog` package
-- **Performance**: Profile regularly with `go tool pprof`
+### Branch Strategy (STRICTLY ENFORCED)
 
-### Code Organization Rules
-- **File Size**: Keep files under 500 lines (split larger files into logical components)
-- **Package Structure**: Follow Go standard layout (cmd/, internal/, pkg/)
-- **Naming**: Use Go naming conventions (PascalCase for exports, camelCase for private)
-- **Documentation**: Document all exported functions with examples
-- **Constants**: Group related constants in blocks with `iota` when appropriate
+**ALL V2 development MUST use feature branches:**
 
-### Required Checks Before Commit
 ```bash
-# Run all checks before committing
-make test && make lint && go mod tidy
+# Branch naming convention (REQUIRED)
+feature/v2/<component>/<task-id>-<description>
 
-# Security scan
-gosec ./...
-
-# Dependency vulnerability check
-go list -json -m all | nancy sleuth
+# Examples:
+feature/v2/parsers/P2-002-uniswap-v2-base
+feature/v2/cache/P3-001-address-index
+feature/v2/arbitrage/P5-001-path-finder
 ```
 
-## System Architecture
-The MEV Bot follows a modular architecture with clearly defined components that communicate through well-defined interfaces.
+**Branch Rules:**
+1. ✅ **ALWAYS** create feature branch from `v2-master-dev`
+2. ✅ **NEVER** commit directly to `v2-master` or `v2-master-dev`
+3. ✅ Branch name MUST match task ID from `07_TASK_BREAKDOWN.md`
+4. ✅ One branch per atomic task (< 2 hours work)
+5. ✅ Delete branch after merge
+6. ✅ Merge feature → v2-master-dev → v2-master

-- `ci`: CI/CD pipeline changes
+**Types**: `feat`, `fix`, `perf`, `refactor`, `test`, `docs`, `build`, `ci`
 
-## 🚨 Security Guidelines
-
-### Never Commit
-- Private keys or wallet seeds
-- API keys or secrets
-- RPC endpoints with authentication
-- Personal configuration files
-
-### Always Validate
-- Input parameters for all functions
-- RPC responses before processing
-- Mathematical calculations for overflow
-- Memory allocations for bounds
-
-### Security Commands
+**Examples:**
 ```bash
-# Scan for secrets
-git-secrets --scan
+# Good commit
+feat(parsers): implement UniswapV3 swap parsing
 
-# Security audit
-gosec ./...
+- Added ParseSwapEvent for V3 with signed amounts
+- Implemented decimal scaling for token precision
+- Added validation for sqrtPriceX96 and liquidity
 
-# Dependency vulnerabilities
-go list -json -m all | nancy sleuth
+Task: P2-011
+Coverage: 100%
+Tests: 23/23 passing
 
-# Check for hardcoded credentials
-grep -r "password\|secret\|key" --exclude-dir=.git .
+# Bad commit (missing task ID, coverage info)
+fix: parser bug
 ```
 
-## 📁 Production Log Management & Operations System
+## Important Notes
 
-### Production Architecture
-The MEV bot uses a comprehensive production-grade log management system with real-time monitoring, analytics, and alerting:
+### What NOT to Do
+- ❌ Modify V1 code in `orig/` (except for critical bugs)
+- ❌ Start V2 implementation without reviewing planning docs
+- ❌ Skip atomic task breakdown from `07_TASK_BREAKDOWN.md`
+- ❌ Implement workarounds instead of fixing root causes
+- ❌ Allow zero addresses or zero amounts to propagate

+### What TO Do
+- ✅ Review foundation implementation in `pkg/` before adding parsers
+- ✅ Follow task breakdown in `07_TASK_BREAKDOWN.md`
+- ✅ Write tests before implementation (TDD - MANDATORY)
+- ✅ Use strict validation at all layers
+- ✅ Add comprehensive logging and metrics
+- ✅ Fix root causes, not symptoms
+- ✅ Always create feature branches from `v2-master-dev`
+- ✅ Run `make validate` before pushing (100% coverage enforced)
+
+## Key Files to Review
+
+### Planning Documents (Complete ✅)
+- `docs/planning/00_V2_MASTER_PLAN.md` - Complete V2 architecture
+- `docs/planning/01_MODULARITY_REQUIREMENTS.md` - Component independence
+- `docs/planning/02_PROTOCOL_SUPPORT_REQUIREMENTS.md` - 13+ DEX protocols
+- `docs/planning/03_TESTING_REQUIREMENTS.md` - 100% coverage enforcement
+- `docs/planning/04_PROFITABILITY_PLAN.md` - Sequencer strategy & ROI
+- `docs/planning/05_CI_CD_SETUP.md` - Complete pipeline documentation
+- `docs/planning/07_TASK_BREAKDOWN.md` - Atomic task list (99+ hours)
+
+### V2 Foundation (Complete ✅ - 100% Coverage)
+- `pkg/types/` - Core types (SwapEvent, PoolInfo, errors)
+- `pkg/parsers/` - Parser factory with routing
+- `pkg/cache/` - Multi-index pool cache (O(1) lookups)
+- `pkg/validation/` - Validation pipeline with rules
+- `pkg/observability/` - Logging & Prometheus metrics
+
+### V1 Reference Implementation
+- `orig/pkg/events/parser.go` - Monolithic parser (reference)
+- `orig/pkg/monitor/concurrent.go` - Arbitrum monitor (reference)
+- `orig/pkg/pools/discovery.go` - Pool discovery (reference)
+- `orig/pkg/arbitrage/detection_engine.go` - Arbitrage detection (reference)
+
+### Documentation
+- `README.md` - Project overview and quick start
+- `CLAUDE.md` - This file (project guidance)
+- `docs/V2_IMPLEMENTATION_STATUS.md` - Implementation progress
+- `Makefile` - Build automation commands
+- `.golangci.yml` - Linter configuration (40+ linters)
+
+## Current Branches
+
+### Production & Development
+- **v2-master** - Production branch for V2 (protected, stable)
+- **v2-master-dev** - Development branch for V2 (protected, stable)
+- **feature/v2-prep** - Planning and foundation (archived, complete)
+
+### Active Development Pattern
+```bash
+# Always branch from v2-master-dev
+git checkout v2-master-dev
+git pull origin v2-master-dev
+git checkout -b feature/v2/<component>/<task-id>-<description>
+
+# Merge back to v2-master-dev via PR
+# Merge v2-master-dev to v2-master when ready for production
 ```

+- **CI/CD:** `.github/workflows/v2-ci.yml` (✅ Configured)
+- **Build Tools:** `Makefile` (✅ Ready - `make validate`)
+- **Git Hooks:** `.git-hooks/` (✅ Install with `./scripts/install-git-hooks.sh`)
 
-### Alert Thresholds
-Automated alerts trigger on:
-- Error rate > 10%
-- Health score < 80
-- Parsing failures > 50
-- Zero address issues > 100
-- CPU usage > 80%
-- Memory usage > 85%
-- Disk usage > 90%
+---
 
-### Configuration
-Customize behavior via `config/log-manager.conf`:
-- Retention policies and size limits
-- Alert thresholds and notification channels
-- Monitoring intervals and daemon settings
-- Compression levels and archive policies
-
-- make sure we keep `TODO_AUDIT_FIX.md` updated at all times
+**Current Phase:** ✅ V2 Foundation Complete (100% Coverage)
+**Next Step:** Phase 2 - Protocol Parser Implementations
+**Foundation:** 3,300+ lines of code (1,500 implementation, 1,800 tests)
+**Status:** Production-ready infrastructure, ready for parsers

+A production-ready MEV (Maximal Extractable Value) bot for Arbitrum that leverages sequencer access to execute profitable arbitrage trades ahead of the chain.
 
-A high-performance MEV (Maximal Extractable Value) bot written in Go that monitors the Arbitrum network for profitable arbitrage opportunities across multiple DEX protocols.
+## Project Status: V2 Architecture Implementation
 
-## 🎯 Overview
+This repository is currently in **V2 implementation phase**. The V1 codebase has been moved to `orig/` for preservation while V2 is being built from the ground up with improved architecture.
 
-This production-ready MEV bot provides real-time monitoring of Arbitrum's sequencer to identify and analyze potential arbitrage opportunities across major decentralized exchanges including Uniswap V2/V3, SushiSwap, Camelot, and Curve Finance.
+**Current State:**
+- V1 implementation: `orig/` (frozen for reference)
+- V2 planning documents: `docs/planning/`
+- V2 implementation: `pkg/`, `cmd/`, `internal/` (in progress)
+- CI/CD pipeline: Fully configured with 100% coverage enforcement

+# MEV Bot V2 - Master Architecture Plan
+
+## Executive Summary
+
+V2 represents a complete architectural overhaul addressing critical parsing, validation, and scalability issues identified in V1. The rebuild focuses on:
+
+1. **Zero Tolerance for Invalid Data**: Eliminate all zero addresses and zero amounts
+2. **Per-Exchange Parser Architecture**: Individual parsers for each DEX type
+3. **Real-time Validation Pipeline**: Background validation with audit trails
+4. **Scalable Pool Discovery**: Efficient caching and multi-index lookups
+5. **Observable System**: Comprehensive metrics, logging, and health monitoring
+
+## Critical Issues from V1
+
+### 1. Zero Address/Amount Problems
+- **Root Cause**: Parser returns zero addresses when transaction data unavailable
+- **Impact**: Invalid events submitted to scanner, wasted computation
+- **V2 Solution**: Strict validation at multiple layers + pool cache enrichment
+
+### 2. Parsing Accuracy Issues
+- **Root Cause**: Monolithic parser handling all DEX types generically
+- **Impact**: Missing token data, incorrect amounts, protocol-specific edge cases
+- **V2 Solution**: Per-exchange parsers with protocol-specific logic
+
+### 3. No Data Quality Audit Trail
+- **Root Cause**: No validation or comparison of parsed data vs cached data
+- **Impact**: Silent failures, no visibility into parsing degradation
+- **V2 Solution**: Background validation channel with discrepancy logging
+
+### 4. Inefficient Pool Lookups
+- **Root Cause**: Single-index cache (by address only)
+- **Impact**: Slow arbitrage path discovery, no ranking by liquidity
+- **V2 Solution**: Multi-index cache (address, token pair, protocol, liquidity)
+
+### 5. Stats Disconnection
+- **Root Cause**: Events detected but not reflected in stats
+- **Impact**: Monitoring blindness, unclear system health
+- **V2 Solution**: Event-driven metrics with guaranteed consistency
+
+## V2 Architecture Principles
+
+### 1. **Fail-Fast with Visibility**
+- Reject invalid data immediately at source
+- Log all rejections with detailed context
+- Never allow garbage data to propagate
+
+### 2. **Single Responsibility**
+- One parser per exchange type
+- One validator per data type
+- One cache per index type
+
+### 3. **Observable by Default**
+- Every component emits metrics
+- Every operation is logged
+- Every error has context
+
+### 4. **Self-Healing**
+- Automatic retry with exponential backoff
+- Fallback to cache when RPC fails
+- Circuit breakers for cascading failures
+
+### 5. **Test-Driven**
+- Unit tests for every parser
+- Integration tests for full pipeline
+- Chaos testing for failure scenarios
+

+# V2 Modularity Requirements
+
+## Core Principle: Standalone Components
+
+**Every component MUST be able to run independently OR as part of the integrated system.**
+
+## Component Independence Rules
+
+### 1. Zero Hard Dependencies
+- Each component communicates through well-defined interfaces only
+- NO direct imports between sibling components
+- NO shared state except through explicit interfaces
+- Each component has its own configuration
+
+### 2. Standalone Executability
+Every component must support:
+```go
+// Example: Each parser can be used standalone
+parser := uniswap_v2.NewParser(logger, cache)
+event, err := parser.ParseLog(log, tx)
+
+// OR as part of factory
+factory := parsers.NewFactory()
+factory.Register(ProtocolUniswapV2, parser)
+```
+
+### 3. Interface-First Design
+Define interfaces BEFORE implementation:
+```go
+// pkg/parsers/interface.go
+type Parser interface {
+    ParseLog(log *types.Log, tx *types.Transaction) (*Event, error)
+    ParseReceipt(receipt *types.Receipt, tx *types.Transaction) ([]*Event, error)
+    SupportedProtocols() []Protocol
+    ValidateEvent(event *Event) error
+}
+
+// Each parser implements this independently
+```
+
+## Component Modularity Matrix
+
+| Component | Standalone Use Case | Integrated Use Case | Interface |
+|-----------|-------------------|---------------------|-----------|
+| UniswapV2Parser | Parse individual V2 transactions | Part of ParserFactory | `Parser` |
+| UniswapV3Parser | Parse individual V3 transactions | Part of ParserFactory | `Parser` |
+| PoolCache | Standalone pool lookup service | Shared cache for all parsers | `PoolCache` |
+| EventValidator | Validate any event independently | Part of validation pipeline | `Validator` |
+| AddressIndex | Standalone address lookup | Part of multi-index cache | `Index` |
+| TokenPairIndex | Standalone pair lookup | Part of multi-index cache | `Index` |
+| BackgroundValidator | Standalone validation service | Part of monitoring pipeline | `BackgroundValidator` |
+

+│       └── validator_test.go
+```
+
+## Testing Requirements for Modularity
+
+### 1. Unit Tests (Component Isolation)
+Each component has 100% independent unit tests:
+```go
+// pkg/parsers/uniswap_v2/parser_test.go
+func TestParser_Standalone(t *testing.T) {
+    // NO dependencies on other parsers
+    // NO dependencies on factory
+    // Uses mocks for interfaces only
+
+    logger := NewMockLogger()
+    cache := NewMockCache()
+
+    parser := NewParser(logger, cache)
+    event, err := parser.ParseLog(mockLog, mockTx)
+
+    assert.NoError(t, err)
+    assert.NotNil(t, event)
+}
+```
+
+### 2. Integration Tests (Component Composition)
+Test components working together:
+```go
+// tests/integration/parser_factory_test.go
+func TestParserFactory_Integration(t *testing.T) {
+    // Test all parsers working through factory
+    factory := parsers.NewFactory()
+
+    // Each parser registered independently
+    factory.Register(ProtocolUniswapV2, uniswap_v2.NewParser(logger, cache))
+    factory.Register(ProtocolUniswapV3, uniswap_v3.NewParser(logger, cache))
+
+    // Test factory routing
+    parser, err := factory.GetParser(ProtocolUniswapV2)
+    assert.NoError(t, err)
+}
+```
+
+### 3. Standalone Executability Tests
+Each component has example main:
+```go
+// examples/uniswap_v2_parser/main.go
+func main() {
+    // Demonstrate standalone usage
+    logger := logger.New("info", "text", "")
+    cache := cache.NewPoolCache()
+
+    parser := uniswap_v2.NewParser(logger, cache)
+
+    // Parse single transaction
+    event, err := parser.ParseLog(log, tx)
+    if err != nil {
+        log.Fatal(err)
+    }
+
+    fmt.Printf("Parsed event: %+v\n", event)
+}
+```
+
+## Dependency Injection Pattern
+
+All components use constructor injection:
+```go
+// Bad: Hard dependency
+type UniswapV2Parser struct {
+    cache *PoolCache  // Hard dependency!
+}
+
+// Good: Interface dependency
+type UniswapV2Parser struct {
+    cache PoolCache  // Interface - can be mocked or replaced
+}
+
+func NewParser(logger Logger, cache PoolCache) *UniswapV2Parser {
+    return &UniswapV2Parser{
+        logger: logger,
+        cache:  cache,
+    }
+}
+```
+
+## Configuration Independence
+
+Each component has its own config:
+```go
+// pkg/parsers/uniswap_v2/config.go
+type Config struct {
+    EnableValidation bool
+    CacheTimeout     time.Duration
+    MaxRetries       int
+}
+
+// Standalone usage
+config := uniswap_v2.Config{
+    EnableValidation: true,
+    CacheTimeout:     5 * time.Minute,
+    MaxRetries:       3,
+}
+parser := uniswap_v2.NewParserWithConfig(logger, cache, config)
+
+// Integrated usage
+factory.RegisterWithConfig(
+    ProtocolUniswapV2,
+    parser,
+    config,
+)
+```
+
+## Interface Contracts
+
+### Minimal Interface Surface
+Each interface has 1-3 methods maximum:
+```go
+// Good: Focused interface
+type Parser interface {
+    ParseLog(log *types.Log, tx *types.Transaction) (*Event, error)
+}
+
+// Bad: God interface
+type Parser interface {
+    ParseLog(log *types.Log, tx *types.Transaction) (*Event, error)
+    ParseReceipt(receipt *types.Receipt, tx *types.Transaction) ([]*Event, error)
+    ValidateEvent(event *Event) error
+    GetStats() Stats
+    Configure(config Config) error
+    // ... too many responsibilities
+}
+```
+
+### Interface Segregation
+Split large interfaces:
+```go
+// Split responsibilities
+type LogParser interface {
+    ParseLog(log *types.Log, tx *types.Transaction) (*Event, error)
+}
+
+type ReceiptParser interface {
+    ParseReceipt(receipt *types.Receipt, tx *types.Transaction) ([]*Event, error)
+}
+
+type EventValidator interface {
+    ValidateEvent(event *Event) error
+}
+
+// Compose as needed
+type Parser interface {
+    LogParser
+    ReceiptParser
+    EventValidator
+}
+```
+
+## Build Tags for Optional Components
+
+Use build tags for optional features:
+```go
+// pkg/parsers/uniswap_v2/parser.go
+// +build !minimal
+
+// Full implementation with all features
+
+// pkg/parsers/uniswap_v2/parser_minimal.go
+// +build minimal
+
+// Minimal implementation for embedded systems
+```
+
+Build options:
+```bash
+# Full build (all components)
+go build ./...
+
+# Minimal build (core only)
+go build -tags minimal ./...
+
+# Custom build (specific parsers only)
+go build -tags "uniswap_v2 uniswap_v3" ./...
+```
+
+## Component Communication Patterns
+
+### 1. Synchronous (Direct Call)
+For tight coupling when needed:
+```go
+event, err := parser.ParseLog(log, tx)
+```
+
+### 2. Asynchronous (Channels)
+For loose coupling:
+```go
+eventChan := make(chan *Event, 100)
+go parser.ParseAsync(logs, eventChan)
+```
+
+### 3. Pub/Sub (Event Bus)
+For many-to-many communication:
+```go
+bus := eventbus.New()
+parser.Subscribe(bus, "parsed")
+validator.Subscribe(bus, "parsed")
+
+bus.Publish("parsed", event)
+```
+
+### 4. Interface Composition
+For static composition:
+```go
+type CompositeParser struct {
+    v2 *uniswap_v2.Parser
+    v3 *uniswap_v3.Parser
+}
+
+func (c *CompositeParser) Parse(log *types.Log) (*Event, error) {
+    // Route to appropriate parser
+}
+```
+
+## Success Criteria for Modularity
+
+Each component MUST:
+- [ ] Compile independently (`go build ./pkg/parsers/uniswap_v2`)
+- [ ] Test independently (`go test ./pkg/parsers/uniswap_v2`)
+- [ ] Run standalone example (`go run examples/uniswap_v2_parser/main.go`)
+- [ ] Have zero sibling dependencies
+- [ ] Communicate only through interfaces
+- [ ] Include standalone usage documentation
+- [ ] Pass integration tests when composed
+- [ ] Support mock implementations for testing
+
+## Anti-Patterns to Avoid
+
+### ❌ Circular Dependencies
+```go
+// pkg/parsers/uniswap_v2/parser.go
+import "pkg/parsers/uniswap_v3"  // BAD!
+
+// pkg/parsers/uniswap_v3/parser.go
+import "pkg/parsers/uniswap_v2"  // BAD!
+```
+
+### ❌ Shared Mutable State
+```go
+// BAD: Global shared state
+var globalCache *PoolCache
+
+func (p *Parser) Parse(log *types.Log) (*Event, error) {
+    pool := globalCache.Get(log.Address)  // BAD!
+}
+```
+
+### ❌ Hard-coded Dependencies
+```go
+// BAD: Creates own dependencies
+func NewParser() *Parser {
+    return &Parser{
+        cache: NewPoolCache(),  // BAD! Should be injected
+    }
+}
+```
+
+### ❌ Leaky Abstractions
+```go
+// BAD: Exposes internal structure
+type Parser interface {
+    GetInternalCache() *PoolCache  // BAD! Leaks implementation
+}
+```
+
+## Migration Strategy
+
+When moving from V1 to V2:
+
+1. **Extract Interface**: Define interface from V1 implementation
+2. **Create Package**: Move to standalone package
+3. **Inject Dependencies**: Replace hard dependencies with interfaces
+4. **Add Tests**: Unit tests for standalone operation
+5. **Create Example**: Standalone usage example
+6. **Document**: README with standalone and integrated usage
+7. **Verify**: Check all modularity criteria
+
+## Component Checklist
+
+Before marking any component as "complete":
+
+- [ ] Compiles independently
+- [ ] Tests independently (>90% coverage)
+- [ ] Has standalone example
+- [ ] Has README with usage
+- [ ] Zero sibling dependencies
+- [ ] All dependencies injected through interfaces
+- [ ] Can be mocked for testing
+- [ ] Integrated into factory/orchestrator
+- [ ] Integration tests pass
+- [ ] Performance benchmarks exist
+- [ ] Documentation complete
+
+---
+
+**Principle**: If you can't run it standalone, it's not modular enough.
+**Guideline**: If you can't mock it, it's too coupled.
+**Rule**: If it has circular dependencies, redesign it.

+## Critical Requirement: Complete Protocol Coverage
+
+**Every protocol MUST be parsed correctly with 100% accuracy and 100% test coverage.**
+
+## Supported DEX Protocols (Complete List)
+
+### Uniswap Family
+1. **Uniswap V2**
+   - Constant product AMM (x * y = k)
+   - Event: `Swap(address indexed sender, uint amount0In, uint amount1In, uint amount0Out, uint amount1Out, address indexed to)`
+   - Pool info: token0, token1, reserves
+   - Fee: 0.3% (30 basis points)
+
+2. **Uniswap V3**
+   - Concentrated liquidity AMM
+   - Event: `Swap(address indexed sender, address indexed recipient, int256 amount0, int256 amount1, uint160 sqrtPriceX96, uint128 liquidity, int24 tick)`
+   - Pool info: token0, token1, fee (500/3000/10000), tickSpacing, sqrtPriceX96, liquidity, tick
+   - CRITICAL: Amounts are signed (int256), handle negative values correctly
+
+3. **Uniswap V4** (planned)
+   - Hooks-based architecture
+   - Event: TBD (monitor for mainnet deployment)
+   - Pool info: Dynamic based on hooks
+
+### Curve Finance
+4. **Curve StableSwap**
+   - Stable asset AMM
+   - Event: `TokenExchange(address indexed buyer, int128 sold_id, uint256 tokens_sold, int128 bought_id, uint256 tokens_bought)`
+   - Pool info: coins array, A (amplification coefficient), fee
+   - CRITICAL: Use int128 for token IDs, proper decimal handling
+
+### Balancer
+5. **Balancer V2**
+   - Weighted pool AMM
+   - Event: `Swap(bytes32 indexed poolId, address indexed tokenIn, address indexed tokenOut, uint256 amountIn, uint256 amountOut)`
+   - Pool info: poolId, tokens array, weights, swapFee
+   - CRITICAL: Uses poolId instead of pool address
+
+6. **Balancer V3** (if deployed on Arbitrum)
+   - Next-gen weighted pools
+   - Event: Monitor for deployment
+   - Pool info: TBD
+
+### Kyber Network
+7. **Kyber Classic**
+   - Dynamic reserve AMM
+   - Event: `KyberTrade(address indexed src, address indexed dest, uint srcAmount, uint dstAmount)`
+   - Pool info: reserveId, tokens, rate
+
+8. **Kyber Elastic**
+   - Concentrated liquidity (similar to Uniswap V3)
+   - Event: `Swap(address indexed sender, address indexed recipient, int256 deltaQty0, int256 deltaQty1, uint160 sqrtP, uint128 liquidity, int24 currentTick)`
+   - Pool info: token0, token1, swapFeeUnits, tickDistance
+   - CRITICAL: Different field names than Uniswap V3 but similar math
+
+### Camelot (Arbitrum Native)
+9. **Camelot V2**
+   - Uniswap V2 fork with dynamic fees
+   - Event: `Swap(address indexed sender, uint amount0In, uint amount1In, uint amount0Out, uint amount1Out, address indexed to)`
+   - Pool info: token0, token1, stableSwap (boolean), fee0, fee1
+   - CRITICAL: Fees can be different for token0 and token1
+
+10. **Camelot V3 (Algebra V1)**
+    - Event: `Swap(address indexed sender, address indexed recipient, int256 amount0, int256 amount1, uint160 price, uint128 liquidity, int24 tick)`
+    - Pool info: token0, token1, fee, tickSpacing (from factory)
+    - Algebra V1 specific
+
+11. **Camelot V3 (Algebra V1.9)**
+    - Enhanced Algebra with adaptive fees
+    - Event: Same as Algebra V1 but with `communityFee` field
+    - Pool info: token0, token1, fee, communityFee, tickSpacing
+    - CRITICAL: Fee can be dynamic
+
+12. **Camelot V3 (Algebra Integral)**

+    - Event: `Swap(address indexed sender, address indexed recipient, int256 amount0, int256 amount1, uint160 price, uint128 liquidity, int24 tick, uint16 fee)`
+    - Pool info: token0, token1, fee (in event!), tickSpacing, plugin address
+    - CRITICAL: Fee is emitted in event, not stored in pool
+
+13. **Camelot V3 (Algebra Directional - All Versions)**
+    - Directional liquidity (different fees for buy/sell)
+    - Event: `Swap(address indexed sender, address indexed recipient, int256 amount0, int256 amount1, uint160 price, uint128 liquidity, int24 tick, uint16 feeZeroToOne, uint16 feeOneToZero)`
+    - Pool info: token0, token1, feeZeroToOne, feeOneToZero, tickSpacing
+    - CRITICAL: Two separate fees based on direction

+## Parsing Requirements
+
+### 1. Sequencer Event Reading
+```go
+type SequencerReader interface {
+    // Subscribe to new blocks
+    Subscribe(ctx context.Context) (<-chan *types.Block, error)
+
+    // Get full transaction receipts
+    GetReceipts(ctx context.Context, txHashes []common.Hash) ([]*types.Receipt, error)
+
+    // Parse block for DEX transactions
+    ParseBlock(block *types.Block) ([]*Transaction, error)
+}
+```
+
+### 2. Multi-Protocol Parser
+```go
+type ProtocolParser interface {
+    // Identify if transaction is for this protocol
+    IsProtocolTransaction(tx *types.Transaction) bool
+
+    // Parse swap event
+    ParseSwapEvent(log *types.Log) (*SwapEvent, error)
+
+    // Parse mint/burn events
+    ParseLiquidityEvent(log *types.Log) (*LiquidityEvent, error)
+
+    // Extract pool info from logs
+    ExtractPoolInfo(logs []*types.Log) (*PoolInfo, error)
+
+    // Validate parsed data
+    Validate(event *SwapEvent) error
+}
+
+type SwapEvent struct {
+    PoolAddress    common.Address
+    Token0         common.Address  // MUST NOT be zero
+    Token1         common.Address  // MUST NOT be zero
+    Amount0In      *big.Int       // MUST NOT be nil or zero (one of In/Out)
+    Amount0Out     *big.Int

+    // V3-specific
+    SqrtPriceX96   *big.Int
+    Liquidity      *big.Int
+    Tick           int24
+
+    // Protocol identification
+    Protocol       Protocol
+    PoolType       PoolType
+}
+```
+
+### 3. Amount Parsing Rules
+
+**CRITICAL: Proper Decimal Handling**
+
+```go
+// Example: Parse Uniswap V2 swap
+func (p *UniswapV2Parser) ParseSwap(log *types.Log) (*SwapEvent, error) {
+    // Decode event
+    event := new(UniswapV2SwapEvent)
+    err := p.abi.UnpackIntoInterface(event, "Swap", log.Data)
+
+    // Get token decimals (CRITICAL!)
+    poolInfo := p.cache.GetPool(log.Address)
+    token0Decimals := poolInfo.Token0Decimals
+    token1Decimals := poolInfo.Token1Decimals
+
+    // MUST use proper decimal scaling
+    amount0In := ScaleAmount(event.Amount0In, token0Decimals)
+    amount0Out := ScaleAmount(event.Amount0Out, token0Decimals)
+    amount1In := ScaleAmount(event.Amount1In, token1Decimals)
+    amount1Out := ScaleAmount(event.Amount1Out, token1Decimals)
+
+    return &SwapEvent{
+        Amount0In: amount0In,
+        Amount0Out: amount0Out,
+        Amount1In: amount1In,
+        Amount1Out: amount1Out,
+    }
+}
+
+// Decimal scaling helper
+func ScaleAmount(amount *big.Int, decimals uint8) *big.Int {
+    // Scale to 18 decimals for internal representation
+    scale := new(big.Int).Exp(
+        big.NewInt(10),
+        big.NewInt(int64(18 - decimals)),
+        nil,
+    )
+    return new(big.Int).Mul(amount, scale)
+}
+```
+
+## Pool Discovery Requirements
+
+### 1. Factory Event Monitoring
+```go
+type PoolDiscovery interface {
+    // Monitor factory for pool creation
+    MonitorFactory(ctx context.Context, factoryAddress common.Address) error
+
+    // Discover pools from transaction
+    DiscoverFromTransaction(tx *types.Transaction, receipt *types.Receipt) ([]*PoolInfo, error)
+
+    // Verify pool exists and get info
+    VerifyPool(ctx context.Context, poolAddress common.Address) (*PoolInfo, error)
+
+    // Save discovered pool
+    SavePool(pool *PoolInfo) error
+}
+```
+
+### 2. Pool Caching Strategy
+```go
+type PoolCache interface {
+    // Add pool to cache
+    Add(pool *PoolInfo) error
+
+    // Get pool by address (O(1))
+    Get(address common.Address) (*PoolInfo, error)
+
+    // Get pools by token pair (O(1))
+    GetByTokenPair(token0, token1 common.Address) ([]*PoolInfo, error)
+
+    // Get pools by protocol (O(1))
+    GetByProtocol(protocol Protocol) ([]*PoolInfo, error)
+
+    // Get top pools by liquidity
+    GetTopByLiquidity(limit int) ([]*PoolInfo, error)
+
+    // Update pool data
+    Update(address common.Address, updates *PoolUpdates) error
+
+    // Save to persistent storage
+    SaveToDisk(path string) error
+
+    // Load from persistent storage
+    LoadFromDisk(path string) error
+}
+```
+
+### 3. Market Building with Mapping
+```go
+type MarketBuilder interface {
+    // Build market from pools
+    BuildMarket(pools []*PoolInfo) (*Market, error)
+
+    // Update market on new swap
+    UpdateOnSwap(market *Market, swap *SwapEvent) (*PriceMovement, error)
+
+    // Get market by token pair (using mapping for O(1) access)
+    GetMarket(token0, token1 common.Address) (*Market, error)
+}
+
+type Market struct {
+    Token0    common.Address
+    Token1    common.Address
+    Pools     map[common.Address]*PoolState  // Mapping for O(1) access
+    BestBid   *big.Float                      // Best price to buy token0
+    BestAsk   *big.Float                      // Best price to sell token0
+    MidPrice  *big.Float                      // Mid-market price
+    Liquidity *big.Int                        // Total liquidity
+    LastUpdate uint64                         // Timestamp
+}
+
+type PoolState struct {
+    Address      common.Address
+    Protocol     Protocol
+    CurrentPrice *big.Float  // With proper decimals
+    Reserve0     *big.Int
+    Reserve1     *big.Int
+    Fee          uint32
+
+    // V3-specific
+    SqrtPriceX96 *big.Int
+    Liquidity    *big.Int
+    Tick         int24
+}
+```
+
+### 4. Price Movement Detection
+```go
+type PriceMovement struct {
+    Market       *Market
+    OldPrice     *big.Float  // Before swap
+    NewPrice     *big.Float  // After swap
+    PriceChange  *big.Float  // Absolute change
+    PercentMove  float64     // Percentage movement
+    TriggeredBy  *SwapEvent
+    Timestamp    uint64
+
+    // Arbitrage opportunity flag
+    IsArbitrageOpportunity bool
+    ExpectedProfit        *big.Float
+}
+
+// CRITICAL: Proper decimal handling in price calculation
+func CalculatePriceMovement(market *Market, swap *SwapEvent) (*PriceMovement, error) {
+    oldPrice := market.MidPrice
+
+    // Update pool state with proper decimals
+    pool := market.Pools[swap.PoolAddress]
+    pool.Reserve0 = new(big.Int).Sub(pool.Reserve0, swap.Amount0Out)
+    pool.Reserve0 = new(big.Int).Add(pool.Reserve0, swap.Amount0In)
+    pool.Reserve1 = new(big.Int).Sub(pool.Reserve1, swap.Amount1Out)
+    pool.Reserve1 = new(big.Int).Add(pool.Reserve1, swap.Amount1In)
+
+    // Calculate new price with EXACT decimal precision
+    newPrice := CalculatePrice(pool.Reserve0, pool.Reserve1,
+        market.Token0Decimals, market.Token1Decimals)
+
+    // Calculate percentage movement
+    priceChange := new(big.Float).Sub(newPrice, oldPrice)
+    percentMove := new(big.Float).Quo(priceChange, oldPrice)
+    percentMove.Mul(percentMove, big.NewFloat(100))
+
+    percent, _ := percentMove.Float64()
+
+    return &PriceMovement{
+        Market:      market,
+        OldPrice:    oldPrice,
+        NewPrice:    newPrice,
+        PriceChange: priceChange,
+        PercentMove: percent,
+        TriggeredBy: swap,
+        Timestamp:   swap.Timestamp,
+    }
+}
+```
+
+## Arbitrage Detection Requirements
+
+### 1. Essential Market Values
+```go
+type ArbitrageMarket struct {
+    // Token pair
+    TokenA common.Address
+    TokenB common.Address
+
+    // All pools for this pair
+    Pools map[common.Address]*PoolState  // O(1) access
+
+    // Price quotes from each pool
+    Quotes map[common.Address]*Quote
+
+    // Liquidity depth
+    LiquidityDepth map[common.Address]*LiquidityBracket
+
+    // Best execution path
+    BestBuyPool  common.Address
+    BestSellPool common.Address
+
+    // Arbitrage opportunity
+    SpreadPercent float64
+    ExpectedProfit *big.Float
+    OptimalAmount  *big.Int
+}
+
+type Quote struct {
+    Pool         common.Address
+    InputAmount  *big.Int
+    OutputAmount *big.Int
+    Price        *big.Float  // With exact decimals
+    Fee          uint32
+    Slippage     float64     // Expected slippage %
+}
+
+type LiquidityBracket struct {
+    Pool      common.Address
+    Amounts   []*big.Int  // Different trade sizes
+    Outputs   []*big.Int  // Expected outputs
+    Slippages []float64   // Slippage at each amount
+}
+```
+
+### 2. Arbitrage Calculator
+```go
+type ArbitrageCalculator interface {
+    // Find arbitrage opportunities
+    FindOpportunities(market *ArbitrageMarket) ([]*Opportunity, error)
+
+    // Calculate optimal trade size
+    CalculateOptimalSize(opp *Opportunity) (*big.Int, error)
+
+    // Calculate expected profit (after gas)
+    CalculateProfit(opp *Opportunity, tradeSize *big.Int) (*big.Float, error)
+
+    // Build execution transaction
+    BuildTransaction(opp *Opportunity, tradeSize *big.Int) (*types.Transaction, error)
+}
+
+type Opportunity struct {
+    Market        *ArbitrageMarket
+    BuyPool       common.Address
+    SellPool      common.Address
+    BuyPrice      *big.Float  // Exact decimals
+    SellPrice     *big.Float  // Exact decimals
+    Spread        float64     // Percentage
+    OptimalAmount *big.Int
+    ExpectedProfit *big.Float // After fees and gas
+    GasCost       *big.Int
+    NetProfit     *big.Float  // After ALL costs
+    Confidence    float64     // 0-1 confidence score
+}
+```
+
+## Transaction Building Requirements
+
+### 1. Single Execution
+```go
+type SingleExecutor interface {
+    // Execute single arbitrage trade
+    Execute(ctx context.Context, opp *Opportunity) (*types.Transaction, error)
+
+    // Build transaction data
+    BuildTxData(opp *Opportunity) ([]byte, error)
+
+    // Estimate gas
+    EstimateGas(ctx context.Context, txData []byte) (uint64, error)
+
+    // Sign and send
+    SignAndSend(ctx context.Context, tx *types.Transaction) (common.Hash, error)
+}
+```
+
+### 2. Batch Execution
+```go
+type BatchExecutor interface {
+    // Execute multiple arbitrage trades in one transaction
+    BatchExecute(ctx context.Context, opps []*Opportunity) (*types.Transaction, error)
+
+    // Build multicall data
+    BuildMulticall(opps []*Opportunity) ([]byte, error)
+
+    // Optimize batch order for maximum profit
+    OptimizeBatchOrder(opps []*Opportunity) []*Opportunity
+
+    // Calculate batch gas savings
+    CalculateGasSavings(opps []*Opportunity) (*big.Int, error)
+}
+
+// Example multicall structure
+type Multicall struct {
+    Targets   []common.Address  // Contract addresses
+    Calldatas [][]byte         // Call data for each
+    Values    []*big.Int       // ETH value for each
+}
+```
+
+## Validation Requirements
+
+### 1. Pool Data Validation
+```go
+// MUST validate ALL fields
+func ValidatePoolInfo(pool *PoolInfo) error {
+    if pool.Address == (common.Address{}) {
+        return errors.New("pool address is zero")
+    }

+    if pool.Token1Decimals == 0 || pool.Token1Decimals > 18 {
+        return errors.New("invalid token1 decimals")
+    }
+
+    // Protocol-specific validation
+    switch pool.PoolType {
+    case PoolTypeConstantProduct:
+        if pool.Reserve0 == nil || pool.Reserve0.Sign() <= 0 {
+            return errors.New("invalid reserve0")
+        }
+        if pool.Reserve1 == nil || pool.Reserve1.Sign() <= 0 {

+            return errors.New("invalid liquidity")
+        }
+    }
+
+    return nil
+}
+```
+
+### 2. Swap Event Validation
+```go
+func ValidateSwapEvent(event *SwapEvent) error {

+    }
+
+    // Amount validation (at least one must be non-zero)
+    hasAmount0 := (event.Amount0In != nil && event.Amount0In.Sign() > 0) ||
+                  (event.Amount0Out != nil && event.Amount0Out.Sign() > 0)
+    hasAmount1 := (event.Amount1In != nil && event.Amount1In.Sign() > 0) ||
+                  (event.Amount1Out != nil && event.Amount1Out.Sign() > 0)
+
+    if !hasAmount0 {
+        return errors.New("both amount0In and amount0Out are zero")
+    }
+    if !hasAmount1 {
+        return errors.New("both amount1In and amount1Out are zero")
+    }
+
+    // Logical validation (can't have both in and out for same token)
+    if event.Amount0In != nil && event.Amount0In.Sign() > 0 &&
+       event.Amount0Out != nil && event.Amount0Out.Sign() > 0 {
+        return errors.New("amount0In and amount0Out both positive")
+    }
+
+    return nil
+}
+```
+
+## Testing Requirements
+
+See `03_TESTING_REQUIREMENTS.md` for comprehensive testing strategy.
+
+Each parser MUST have:
+- Unit tests for all event types (100% coverage)
+- Integration tests with real Arbiscan data
+- Edge case tests (zero amounts, max values, etc.)
+- Decimal precision tests
+- Gas estimation tests
+
+---
+
+**CRITICAL**: All protocols must be supported. All decimals must be handled correctly. All validation must pass. No exceptions.

+
+## Test Types and Requirements
+
+### 1. Unit Tests (100% Coverage Required)
+
+Every function, every method, every code path MUST be tested.
+
+```go
+// Example: Complete unit test coverage
+package uniswap_v2
+
+import (
+    "testing"
+    "github.com/stretchr/testify/assert"
+    "github.com/stretchr/testify/require"
+)
+
+func TestParser_ParseSwapEvent_Success(t *testing.T) {
+    // Test successful parsing
+}
+
+func TestParser_ParseSwapEvent_ZeroAddress(t *testing.T) {
+    // Test zero address rejection
+}
+
+func TestParser_ParseSwapEvent_ZeroAmounts(t *testing.T) {
+    // Test zero amount rejection
+}
+
+func TestParser_ParseSwapEvent_MaxValues(t *testing.T) {
+    // Test maximum value handling
+}
+
+func TestParser_ParseSwapEvent_MinValues(t *testing.T) {
+    // Test minimum value handling
+}
+
+func TestParser_ParseSwapEvent_InvalidLog(t *testing.T) {
+    // Test invalid log handling
+}
+
+func TestParser_ParseSwapEvent_NilTransaction(t *testing.T) {
+    // Test nil transaction handling
+}
+
+func TestParser_ParseSwapEvent_Decimals(t *testing.T) {
+    // Test decimal precision handling
+    tests := []struct{
+        name          string
+        token0Dec     uint8
+        token1Dec     uint8

+        {"WBTC-WETH", 8, 18, big.NewInt(100000000), ...},
+    }
+    // Test all combinations
+}
+
+// MUST test ALL error paths
+func TestParser_ParseSwapEvent_AllErrors(t *testing.T) {
+    tests := []struct{
+        name    string
+        log     *types.Log
+        wantErr string
+    }{
+        {"nil log", nil, "log is nil"},
+        {"wrong signature", wrongSigLog, "invalid signature"},
+        {"malformed data", malformedLog, "failed to decode"},
+        // ... every possible error
+    }
+
+    for _, tt := range tests {
+        t.Run(tt.name, func(t *testing.T) {
+            _, err := parser.ParseSwapEvent(tt.log)
+            require.Error(t, err)
+            assert.Contains(t, err.Error(), tt.wantErr)
+        })
+    }
+}
+```
+
+### 2. Integration Tests (Real Data Required)
+
+Test with REAL transactions from Arbiscan.
+
+```go
+// Example: Integration test with real Arbiscan data
+func TestUniswapV2Parser_RealTransaction(t *testing.T) {
+    // Load real transaction from Arbiscan
+    // txHash: 0x1234...
+    realTx := loadTransaction("testdata/uniswap_v2_swap_0x1234.json")
+    realReceipt := loadReceipt("testdata/uniswap_v2_receipt_0x1234.json")
+
+    parser := NewParser(logger, cache)
+    events, err := parser.ParseReceipt(realReceipt, realTx)
+
+    require.NoError(t, err)
+    require.Len(t, events, 1)
+
+    event := events[0]
+
+    // Verify against known values from Arbiscan
+    assert.Equal(t, "0x...", event.Token0.Hex())
+    assert.Equal(t, "0x...", event.Token1.Hex())
+    assert.Equal(t, big.NewInt(1000000), event.Amount0In)
+    // ... verify all fields match Arbiscan
+}
+
+// MUST test multiple real transactions per protocol
+func TestUniswapV2Parser_RealTransactions_Comprehensive(t *testing.T) {
+    testCases := []string{
+        "0x1234", // Basic swap
+        "0x5678", // Swap with ETH
+        "0x9abc", // Multi-hop swap
+        "0xdef0", // Large amount swap
+        "0x2468", // Small amount swap
+    }
+
+    for _, txHash := range testCases {
+        t.Run(txHash, func(t *testing.T) {
+            // Load and test real transaction
+        })
+    }
+}
+```
+
+### 3. Edge Case Tests (Comprehensive)
+
+Test EVERY edge case imaginable.
+
+```go
+func TestParser_EdgeCases(t *testing.T) {
+    tests := []struct{
+        name        string
+        setupFunc   func() *types.Log
+        expectError bool
+        errorMsg    string
+    }{
+        // Boundary values
+        {"max uint256", setupMaxUint256, false, ""},
+        {"min uint256", setupMinUint256, false, ""},
+        {"zero amount", setupZeroAmount, true, "zero amount"},
+
+        // Token edge cases
+        {"same token0 and token1", setupSameTokens, true, "same token"},
+        {"token0 > token1 (not sorted)", setupUnsorted, false, ""},
+
+        // Decimal edge cases
+        {"0 decimals", setupZeroDecimals, true, "invalid decimals"},
+        {"19 decimals", setup19Decimals, true, "invalid decimals"},
+        {"different decimals", setupDifferentDecimals, false, ""},
+
+        // Amount edge cases
+        {"both in amounts zero", setupBothInZero, true, "zero amount"},
+        {"both out amounts zero", setupBothOutZero, true, "zero amount"},
+        {"negative amount (V3)", setupNegativeAmount, false, ""},
+
+        // Address edge cases
+        {"zero token0 address", setupZeroToken0, true, "zero address"},
+        {"zero token1 address", setupZeroToken1, true, "zero address"},
+        {"zero pool address", setupZeroPool, true, "zero address"},

+        {"truncated log data", setupTruncatedData, true, "invalid data"},
+        {"extra log data", setupExtraData, false, ""},
+
+        // Overflow cases
+        {"amount overflow", setupOverflow, false, ""},
+        {"price overflow", setupPriceOverflow, false, ""},
+        {"liquidity overflow", setupLiquidityOverflow, false, ""},
+    }
+
+    for _, tt := range tests {
+        t.Run(tt.name, func(t *testing.T) {
+            log := tt.setupFunc()
+            event, err := parser.ParseSwapEvent(log)
+
+            if tt.expectError {
+                require.Error(t, err)
+                assert.Contains(t, err.Error(), tt.errorMsg)
+                assert.Nil(t, event)
+            } else {
+                require.NoError(t, err)
+                assert.NotNil(t, event)
+            }
+        })
+    }
+}
+```
+
+### 4. Decimal Precision Tests (Critical)
+
+MUST test decimal handling with EXACT precision.
+
+```go
+func TestDecimalPrecision(t *testing.T) {
+    tests := []struct{
+        name           string
+        token0Decimals uint8
+        token1Decimals uint8
+        reserve0       *big.Int
+        reserve1       *big.Int
+        expectedPrice  string  // Exact decimal string
+    }{
+        {
+            name:           "USDC/WETH (6/18)",
+            token0Decimals: 6,
+            token1Decimals: 18,
+            reserve0:       big.NewInt(1000000),      // 1 USDC
+            reserve1:       big.NewInt(1e18),         // 1 WETH
+            expectedPrice:  "1.000000000000000000",   // Exact
+        },
+        {
+            name:           "WBTC/WETH (8/18)",
+            token0Decimals: 8,
+            token1Decimals: 18,
+            reserve0:       big.NewInt(100000000),    // 1 WBTC
+            reserve1:       big.NewInt(15.5 * 1e18),  // 15.5 WETH
+            expectedPrice:  "15.500000000000000000",  // Exact
+        },
+        {
+            name:           "DAI/USDC (18/6)",
+            token0Decimals: 18,
+            token1Decimals: 6,
+            reserve0:       big.NewInt(1e18),         // 1 DAI
+            reserve1:       big.NewInt(999000),       // 0.999 USDC
+            expectedPrice:  "0.999000000000000000",   // Exact
+        },
+    }
+
+    for _, tt := range tests {
+        t.Run(tt.name, func(t *testing.T) {
+            price := CalculatePrice(
+                tt.reserve0,
+                tt.reserve1,
+                tt.token0Decimals,
+                tt.token1Decimals,
+            )
+
+            // MUST match exactly
+            assert.Equal(t, tt.expectedPrice, price.Text('f', 18))
+        })
+    }
+}
+
+// Test rounding errors
+func TestDecimalRounding(t *testing.T) {
+    // Ensure no precision loss through multiple operations
+    initial := new(big.Float).SetPrec(256).SetFloat64(1.123456789012345678)
+
+    // Simulate multiple swaps
+    result := initial
+    for i := 0; i < 1000; i++ {
+        result = simulateSwap(result)
+    }
+
+    // Should maintain precision
+    diff := new(big.Float).Sub(initial, result)
+    tolerance := new(big.Float).SetFloat64(1e-15)
+
+    assert.True(t, diff.Cmp(tolerance) < 0, "precision loss detected")
+}
+```
+
+### 5. Concurrency Tests (Thread Safety)
+
+Test concurrent access to shared resources.
+
+```go
+func TestPoolCache_Concurrency(t *testing.T) {
+    cache := NewPoolCache()
+
+    // Concurrent writes
+    var wg sync.WaitGroup
+    for i := 0; i < 100; i++ {
+        wg.Add(1)
+        go func(id int) {
+            defer wg.Done()
+            pool := createTestPool(id)
+            err := cache.Add(pool)
+            assert.NoError(t, err)
+        }(i)
+    }
+
+    // Concurrent reads
+    for i := 0; i < 100; i++ {
+        wg.Add(1)
+        go func(id int) {
+            defer wg.Done()
+            pool, err := cache.Get(testAddress(id))
+            assert.NoError(t, err)
+            if pool != nil {
+                assert.NotNil(t, pool.Token0)
+            }
+        }(i)
+    }
+
+    wg.Wait()
+
+    // Verify no data corruption
+    for i := 0; i < 100; i++ {
+        pool, err := cache.Get(testAddress(i))
+        require.NoError(t, err)
+        if pool != nil {
+            ValidatePoolInfo(pool)  // MUST pass validation
+        }
+    }
+}
+
+// Test race conditions
+func TestPoolCache_RaceConditions(t *testing.T) {
+    // Run with: go test -race
+    cache := NewPoolCache()
+
+    done := make(chan bool)
+
+    // Writer goroutine
+    go func() {
+        for i := 0; i < 1000; i++ {
+            cache.Add(createTestPool(i))
+        }
+        done <- true
+    }()
+
+    // Reader goroutines
+    for i := 0; i < 10; i++ {
+        go func() {
+            for j := 0; j < 1000; j++ {
+                cache.Get(testAddress(j % 100))
+            }
+            done <- true
+        }()
+    }
+
+    // Wait for completion
+    for i := 0; i < 11; i++ {
+        <-done
+    }
+}
+```
+
+### 6. Performance Tests (Benchmarks Required)
+
+MUST benchmark all critical paths.
+
+```go
+func BenchmarkParser_ParseSwapEvent(b *testing.B) {
+    parser := setupParser()
+    log := createTestLog()
+
+    b.ResetTimer()
+    for i := 0; i < b.N; i++ {
+        _, _ = parser.ParseSwapEvent(log)
+    }
+}
+
+// MUST meet performance targets
+func BenchmarkParser_ParseSwapEvent_Target(b *testing.B) {
+    parser := setupParser()
+    log := createTestLog()
+
+    b.ResetTimer()
+    start := time.Now()
+
+    for i := 0; i < b.N; i++ {
+        _, _ = parser.ParseSwapEvent(log)
+    }
+
+    elapsed := time.Since(start)
+    avgTime := elapsed / time.Duration(b.N)
+
+    // MUST complete in < 1ms
+    if avgTime > time.Millisecond {
+        b.Fatalf("Too slow: %v per operation (target: < 1ms)", avgTime)
+    }
+}
+
+// Memory allocation benchmarks
+func BenchmarkParser_ParseSwapEvent_Allocs(b *testing.B) {
+    parser := setupParser()
+    log := createTestLog()
+
+    b.ReportAllocs()
+    b.ResetTimer()
+
+    for i := 0; i < b.N; i++ {
+        _, _ = parser.ParseSwapEvent(log)
+    }
+
+    // Check allocation count
+    // Should minimize allocations
+}
+```
+
+### 7. Protocol-Specific Tests
+
+Each protocol MUST have comprehensive test suite.
+
+```go
+// Uniswap V2
+func TestUniswapV2_AllEventTypes(t *testing.T) {
+    tests := []string{"Swap", "Mint", "Burn", "Sync"}
+    // Test all event types
+}
+
+// Uniswap V3
+func TestUniswapV3_AllEventTypes(t *testing.T) {
+    tests := []string{"Swap", "Mint", "Burn", "Flash", "Collect"}
+    // Test all event types + V3 specific logic
+}
+
+// Curve
+func TestCurve_AllPoolTypes(t *testing.T) {
+    tests := []string{"StableSwap", "CryptoSwap", "Tricrypto"}
+    // Test all Curve variants
+}
+
+// Camelot Algebra versions
+func TestCamelot_AllAlgebraVersions(t *testing.T) {
+    tests := []string{"AlgebraV1", "AlgebraV1.9", "AlgebraIntegral", "AlgebraDirectional"}
+    // Test all Algebra variants with different fee structures
+}
+```
+
+### 8. Integration Test Suite
+
+Complete end-to-end testing.
+
+```go
+func TestE2E_FullPipeline(t *testing.T) {
+    // Setup full system
+    monitor := setupMonitor()
+    factory := setupParserFactory()
+    cache := setupCache()
+    validator := setupValidator()
+    arbDetector := setupArbitrageDetector()
+
+    // Feed real block data
+    block := loadRealBlock("testdata/block_12345.json")
+
+    // Process through full pipeline
+    txs := monitor.ParseBlock(block)
+    for _, tx := range txs {
+        events, err := factory.ParseTransaction(tx)
+        require.NoError(t, err)
+
+        for _, event := range events {
+            // Validate
+            err = validator.Validate(event)
+            require.NoError(t, err)
+
+            // Update cache
+            cache.UpdateFromEvent(event)
+
+            // Check for arbitrage
+            opps, err := arbDetector.FindOpportunities(event)
+            require.NoError(t, err)
+
+            for _, opp := range opps {
+                // Verify opportunity is valid
+                ValidateOpportunity(opp)
+            }
+        }
+    }
+
+    // Verify final state
+    assert.True(t, cache.Size() > 0)
+    assert.True(t, validator.GetStats().TotalValidated > 0)
+}
+```
+

+
+## Local Development Workflow
+
+### Git Hooks
+
+#### Pre-Commit Hook
+
+Location: `.git-hooks/pre-commit`
+
+**Checks performed:**
+1. Branch name validation
+2. Merge conflict detection
+3. Secret and forbidden pattern detection
+4. go.mod/go.sum tidiness
+5. Code formatting (auto-fix)
+6. Quick tests on changed packages
+7. go vet static analysis
+8. File size warnings
+
+**Installation:**
+```bash
+./scripts/install-git-hooks.sh
+```
+
+**Manual bypass (emergency only):**
+```bash
+git commit --no-verify
+```
+
+#### Commit-msg Hook
+
+Location: `.git-hooks/commit-msg`
+
+**Validates:**
+- Commit message format: `type(scope): description`
+- Valid types: feat, fix, perf, refactor, test, docs, build, ci
+- Minimum description length: 10 characters
+- Maximum first line: 72 characters (warning)
+
+**Example valid commit:**
+```
+feat(parsers): add UniswapV2 parser with event validation
+
+- Implements ParseLog() for Swap events
+- Adds token extraction from pool cache
+- Includes comprehensive validation rules
+- Achieves 100% test coverage
+

+Co-Authored-By: Claude <noreply@anthropic.com>
+```
+
+### Local Testing Commands
+
+```bash
+# Quick pre-commit check
+make pre-commit
+
+# Full local CI validation (mimics GitHub Actions)
+make validate
+
+# Individual checks
+make fmt           # Format code
+make test          # Run all tests
+make test-coverage # Run tests with 100% coverage enforcement
+make lint          # Run linters
+make security      # Security scan
+
+# Build
+make build
+
+# Dependencies
+make deps-tidy
+make deps-check
+```
+
+## GitHub Actions Pipeline
+
+### Workflow: v2-ci.yml
+
+**Triggers:**
+- Push to `feature/v2-**` or `feature/v2/**` branches
+- Pull requests to `feature/v2-prep` or `master`
+- Manual workflow dispatch
+
+**Environment:**
+- Go version: 1.25
+- Minimum coverage: 100%
+- golangci-lint version: v1.61.0
+
+### Pipeline Jobs
+
+#### 1. Pre-Flight Checks
+
+**Purpose:** Validate branch naming and commit messages
+
+**Checks:**
+- Branch name follows convention: `feature/v2/<component>/<TASK-ID>-<description>`
+- Commit message follows format: `type(scope): description`
+
+**Example branch names:**
+```
+feature/v2/parsers/P2-002-uniswap-v2-base
+feature/v2/cache/P3-001-address-index
+feature/v2/validation/P4-001-validation-rules
+```
+
+**Failure behavior:** Block pipeline if validation fails
+
+#### 2. Build & Dependencies
+
+**Purpose:** Ensure code compiles and dependencies are correct
+
+**Steps:**
+1. Set up Go 1.25
+2. Download and cache dependencies
+3. Verify dependencies
+4. Check go.mod tidiness
+5. Build all packages
+6. Build main binary (if exists)
+
+**Caching:**
+- Go modules: `~/go/pkg/mod`
+- Build cache: `~/.cache/go-build`
+- Cache key: `${{ runner.os }}-go-${{ GO_VERSION }}-${{ hashFiles('**/go.sum') }}`
+
+**Failure behavior:** Pipeline stops if build fails
+
+#### 3. Code Quality & Linting
+
+**Purpose:** Enforce code quality standards
+
+**Checks:**
+1. **gofmt** - Code formatting
+2. **go vet** - Static analysis
+3. **golangci-lint** - Comprehensive linting
+4. **gosec** - Security scanning
+5. **TODO/FIXME detection** - Warning only
+
+**Configuration:** `.golangci.yml`
+
+**Enabled linters (40+):**
+- errcheck, gosimple, govet, ineffassign, staticcheck, typecheck, unused
+- bodyclose, cyclop, dupl, errname, exhaustive, exportloopref
+- gocognit, goconst, gocritic, gocyclo, godot, goimports
+- gomnd, gosec, lll, misspell, nakedret, nestif
+- And many more...
+
+**Failure behavior:** Pipeline stops if linting fails
+
+#### 4. Unit Tests (100% Coverage Enforcement)
+
+**Purpose:** Run all tests with mandatory 100% coverage
+
+**Steps:**
+1. Run tests with race detector
+2. Generate coverage report
+3. Calculate coverage percentage
+4. **ENFORCE 100% COVERAGE REQUIREMENT**
+5. Upload coverage to Codecov
+6. Generate HTML coverage report
+
+**Coverage calculation:**
+```bash
+COVERAGE=$(go tool cover -func=coverage.out | grep total | awk '{print $3}' | sed 's/%//')
+
+if (( $(echo "$COVERAGE < 100" | bc -l) )); then
+    echo "❌ COVERAGE FAILURE"
+    exit 1
+fi
+```
+
+**Failure behavior:** Pipeline STOPS if coverage < 100%
+
+**Artifacts uploaded:**
+- `coverage.out` - Coverage profile
+- `coverage.html` - HTML coverage report
+
+#### 5. Integration Tests
+
+**Purpose:** Test component interactions
+
+**Triggers:**
+- Commit message contains `[integration]`
+- Pull request events
+
+**Tests:**
+- Integration tests (tag: `integration`)
+- End-to-end tests (if exists)
+
+**Timeout:** 30 minutes
+
+#### 6. Performance Benchmarks
+
+**Purpose:** Ensure performance targets are met
+
+**Triggers:**
+- Manual workflow dispatch with `run_benchmarks: true`
+- Commit message contains `[bench]`
+
+**Benchmarks:**
+- Parser performance: < 5ms per transaction
+- Arbitrage detection: < 10ms
+- End-to-end: < 50ms
+
+**Command:**
+```bash
+go test -bench=. -benchmem -benchtime=10s ./...
+```
+
+**Artifacts uploaded:**
+- `benchmark.txt` - Detailed benchmark results (retained 90 days)
+
+#### 7. Decimal Precision Tests
+
+**Purpose:** Validate critical decimal handling
+
+**Tests:**
+- Decimal scaling accuracy
+- Rounding error accumulation
+- Cross-protocol decimal handling
+- Edge case decimal values
+
+**Failure behavior:** Pipeline stops if decimal tests fail
+
+#### 8. Modularity Validation
+
+**Purpose:** Ensure component independence
+
+**Checks:**
+1. Each `pkg/*` compiles independently
+2. No circular dependencies
+3. Standalone executability
+
+**Command:**
+```bash
+for dir in pkg/*/; do
+    (cd "$dir" && go build .) || exit 1
+done
+```
+
+**Dependency check:**
+```bash
+godepgraph ./... | grep -i cycle && exit 1
+```
+
+**Failure behavior:** Pipeline stops if modularity fails
+
+#### 9. Final Validation Summary
+
+**Purpose:** Aggregate all results and determine deployment readiness
+
+**Checks all jobs:**
+- Pre-flight ✅
+- Build ✅
+- Code quality ✅
+- Unit tests (100% coverage) ✅
+- Modularity ✅
+- Decimal precision ✅
+
+**Generates:**
+- CI/CD summary markdown
+- Deployment readiness status
+
+**PR Comments:**
+- Automatically comments on PRs with summary
+
+**Failure behavior:**
+- Exit 0 if all checks pass
+- Exit 1 if any check fails
+
+## Performance Optimizations
+
+### Caching Strategy
+
+**Go Modules Cache:**
+```yaml
+uses: actions/cache@v4
+with:
+  path: |
+    ~/.cache/go-build
+    ~/go/pkg/mod
+  key: ${{ runner.os }}-go-${{ GO_VERSION }}-${{ hashFiles('**/go.sum') }}
+  restore-keys: |
+    ${{ runner.os }}-go-${{ GO_VERSION }}-
+```
+
+**Benefits:**
+- Faster dependency downloads
+- Reduced bandwidth usage
+- Faster builds (2-5x speedup)
+
+### Parallel Execution
+
+**Jobs run in parallel:**
+- Code quality & Unit tests (independent)
+- Modularity & Decimal tests (after unit tests)
+- Integration & Benchmarks (after unit tests)
+
+**Estimated pipeline time:**
+- Pre-flight: 30 seconds
+- Build: 1-2 minutes
+- Code quality: 2-3 minutes
+- Unit tests: 3-5 minutes
+- Integration tests: 5-10 minutes
+- Total: 10-15 minutes (with caching)
+
+## Failure Handling

+### Pipeline Stops On:
+
+1. **Pre-flight failures:**
+   - Invalid branch name
+   - Invalid commit message
+
+2. **Build failures:**
+   - Compilation errors
+   - Untidy dependencies
+
+3. **Code quality failures:**
+   - Formatting issues
+   - Linting errors
+   - Security vulnerabilities

+# Fix formatting
+make fmt
+
+# Fix coverage
+make test-coverage
+
+# Fix linting
+make lint
+
+# Fix dependencies
+make deps-tidy
+```
+
+## Branch Protection Rules

+- `master`
+- `feature/v2-prep`
+
+### Required Status Checks:
+- ✅ Pre-Flight Checks
+- ✅ Build & Dependencies
+- ✅ Code Quality & Linting
+- ✅ Unit Tests (100% Coverage)
+- ✅ Modularity Validation
+- ✅ Decimal Precision Tests
+
+### Additional Rules:

+- Do not allow bypassing the above settings
+
+## Deployment
+
+### Deployment Ready Criteria:
+
+**All of the following must be true:**
+1. All CI/CD checks pass ✅
+2. Code coverage = 100% ✅
+3. No security vulnerabilities ✅
+4. All components compile independently ✅
+5. Performance benchmarks meet targets ✅
+6. Pull request approved ✅
+
+### Deployment Process:
+
+```bash
+# 1. Merge to v2-prep
+git checkout feature/v2-prep
+git merge feature/v2/parsers/P2-002-uniswap-v2-base
+
+# 2. Verify CI passes
+# (GitHub Actions runs automatically)

+2. **Verify test coverage** (should always be 100%)
+3. **Review security scan results**
+4. **Ensure modularity is maintained**
+5. **Verify performance benchmarks** (if applicable)
+
+### For Maintainers:
+
+1. **Monitor pipeline success rate**
+2. **Update dependencies regularly**
+3. **Review and update linter rules**
+4. **Optimize caching strategy**
+5. **Keep documentation up to date**
+
+## Troubleshooting
+
+### Common Issues:
+
+**1. Coverage not 100%:**
+```bash
+# View uncovered lines
+make test-coverage
+
+# Check specific package
+go test -coverprofile=coverage.out ./pkg/parsers
+go tool cover -func=coverage.out | grep -v "100.0%"
+```
+
+**2. Linting failures:**
+```bash
+# Run locally
+make lint
+
+# Auto-fix some issues
+golangci-lint run --fix
+```
+
+**3. Test failures:**
+```bash
+# Run with verbose output
+go test -v ./...
+
+# Run specific test
