Implemented complete validation pipeline with comprehensive tests:

Validator (pkg/validation/validator.go):
- Configurable validation rules (min/max amounts, blacklists, protocol whitelist)
- ValidateSwapEvent() with multi-layer validation
- ValidatePoolInfo() with pool-specific checks
- FilterValid() for batch validation
- GetValidationRules() for rule inspection
- Supports zero address/amount rejection
- Amount threshold validation (min/max)
- Protocol whitelist enforcement
- Pool/token blacklist enforcement

Validation Rules (pkg/validation/interface.go):
- DefaultValidationRules() with sensible defaults
- Configurable thresholds and blacklists
- Protocol-specific validation support
- Decimal precision validation flag
- Max slippage configuration (basis points)

Tests (pkg/validation/validator_test.go):
- TestNewValidator - validator creation
- TestDefaultValidationRules - default configuration
- TestValidator_ValidateSwapEvent - comprehensive scenarios
  * Valid events
  * Nil events
  * Below minimum amount
  * Above maximum amount
  * Protocol not allowed
  * Blacklisted pool
  * Blacklisted token
  * Zero amounts
- TestValidator_ValidatePoolInfo - pool validation scenarios
  * Valid pools
  * Nil pools
  * Protocol restrictions
  * Blacklists
- TestValidator_FilterValid - batch filtering
  * All valid
  * Mixed valid/invalid
  * All invalid
  * Empty slices
- TestValidator_GetValidationRules - rule retrieval
- Test_isZero_Validation - helper function
- 100% code coverage

Features:
- Multi-layer validation (built-in + rule-based)
- Flexible configuration
- Defensive programming
- Comprehensive error messages
- Batch filtering support

Task: P4-001 through P4-003 Validation Pipeline ✅ Complete
Coverage: 100% (enforced)
Next: UniswapV2 parser demonstration

Created complete V2 foundation infrastructure for modular MEV bot:

Core Types (pkg/types/):
- swap.go: SwapEvent with protocol support for 13+ DEXs
- pool.go: PoolInfo with multi-index cache support
- errors.go: Comprehensive error definitions
- Full validation methods and helper functions
- Proper decimal scaling (18 decimals internal representation)

Parser Interface (pkg/parsers/):
- Parser interface for protocol-specific implementations
- Factory interface for routing and registration
- Support for single log and full transaction parsing
- SupportsLog() for dynamic protocol identification

Cache Interface (pkg/cache/):
- PoolCache interface with multi-index support
- O(1) lookups by: address, token pair, protocol, liquidity
- Add, Update, Remove, Count, Clear operations
- Context-aware for cancellation support

Validation Interface (pkg/validation/):
- Validator interface for swap events and pools
- ValidationRules with configurable thresholds
- FilterValid() for batch validation
- Zero address, zero amount, decimal precision checks

Observability (pkg/observability/):
- Logger interface with structured logging (slog)
- Metrics interface with Prometheus integration
- Performance tracking (parse latency, execution)
- Business metrics (arbitrage opportunities, profit)

Project Files:
- go.mod: Module definition with ethereum and prometheus deps
- README.md: Complete project overview and documentation

Architecture Principles:
- Interface-first design for testability
- Single responsibility per interface
- Dependency injection ready
- Observable by default
- 18 decimal internal representation

Ready for Phase 1 implementation:
- All interfaces defined
- Error types established
- Core types validated
- Logging and metrics infrastructure ready

Next: Implement protocol-specific parsers (P2-001 through P2-055)

803de231ba feat: create v2-prep branch with comprehensive planning 
Restructured project for V2 refactor:

**Structure Changes:**
- Moved all V1 code to orig/ folder (preserved with git mv)
- Created docs/planning/ directory
- Added orig/README_V1.md explaining V1 preservation

**Planning Documents:**
- 00_V2_MASTER_PLAN.md: Complete architecture overview
  - Executive summary of critical V1 issues
  - High-level component architecture diagrams
  - 5-phase implementation roadmap
  - Success metrics and risk mitigation

- 07_TASK_BREAKDOWN.md: Atomic task breakdown
  - 99+ hours of detailed tasks
  - Every task < 2 hours (atomic)
  - Clear dependencies and success criteria
  - Organized by implementation phase

**V2 Key Improvements:**
- Per-exchange parsers (factory pattern)
- Multi-layer strict validation
- Multi-index pool cache
- Background validation pipeline
- Comprehensive observability

**Critical Issues Addressed:**
- Zero address tokens (strict validation + cache enrichment)
- Parsing accuracy (protocol-specific parsers)
- No audit trail (background validation channel)
- Inefficient lookups (multi-index cache)
- Stats disconnection (event-driven metrics)

Next Steps:
1. Review planning documents
2. Begin Phase 1: Foundation (P1-001 through P1-010)
3. Implement parsers in Phase 2
4. Build cache system in Phase 3
5. Add validation pipeline in Phase 4
6. Migrate and test in Phase 5
