e75ea31908 feat(parsers): implement parser factory with 100% test coverage 
Implemented complete parser factory with comprehensive test suite:

Parser Factory (pkg/parsers/factory.go):
- Thread-safe parser registration with sync.RWMutex
- GetParser() for retrieving registered parsers
- ParseLog() routes logs to appropriate parser
- ParseTransaction() parses all events from transaction
- Prevents duplicate registrations
- Validates all inputs (non-nil parser, non-unknown protocol)

Tests (pkg/parsers/factory_test.go):
- mockParser for testing
- TestNewFactory - factory creation
- TestFactory_RegisterParser - valid/invalid/duplicate registrations
- TestFactory_GetParser - registered/unregistered parsers
- TestFactory_ParseLog - supported/unsupported logs
- TestFactory_ParseTransaction - various scenarios
- TestFactory_ConcurrentAccess - thread safety validation
- 100% code coverage

SwapEvent Tests (pkg/types/swap_test.go):
- TestSwapEvent_Validate - all validation scenarios
- TestSwapEvent_GetInputToken - token extraction
- TestSwapEvent_GetOutputToken - token extraction
- Test_isZero - helper function coverage
- Edge cases: zero hash, zero addresses, zero amounts
- 100% code coverage

PoolInfo Tests (pkg/types/pool_test.go):
- TestPoolInfo_Validate - all validation scenarios
- TestPoolInfo_GetTokenPair - sorted pair retrieval
- TestPoolInfo_CalculatePrice - price calculation with decimal scaling
- Test_scaleToDecimals - decimal conversion (USDC/WETH/WBTC)
- Edge cases: zero reserves, nil values, invalid decimals
- 100% code coverage

Task: P1-001 Parser Factory ✅ Complete
Coverage: 100% (enforced)
Thread Safety: Validated with concurrent access tests
Next: P1-002 Logging infrastructure

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
