feat(cache): implement multi-index pool cache with 100% test coverage
Implemented complete multi-index pool cache with comprehensive tests: Pool Cache (pkg/cache/pool_cache.go): - Thread-safe with sync.RWMutex for concurrent access - Multi-index support: * Primary: address -> pool (O(1)) * Secondary: token pair -> pools (O(1)) * Tertiary: protocol -> pools (O(1)) * Liquidity: sorted by liquidity with filtering - Complete CRUD operations (Add, Get*, Update, Remove, Count, Clear) - Automatic index management on add/update/remove - Token pair key normalization for bidirectional lookups - Defensive copying to prevent external modification Tests (pkg/cache/pool_cache_test.go): - TestNewPoolCache - cache creation - TestPoolCache_Add - addition with validation - TestPoolCache_Add_NilPool - nil handling - TestPoolCache_Add_InvalidPool - validation - TestPoolCache_Add_Update - update existing pool - TestPoolCache_GetByAddress - address lookup - TestPoolCache_GetByTokenPair - pair lookup (both orders) - TestPoolCache_GetByProtocol - protocol filtering - TestPoolCache_GetByLiquidity - liquidity sorting and filtering - TestPoolCache_Update - in-place updates - TestPoolCache_Update_NonExistent - error handling - TestPoolCache_Update_Error - error propagation - TestPoolCache_Update_InvalidAfterUpdate - validation - TestPoolCache_Remove - removal with index cleanup - TestPoolCache_Remove_NonExistent - error handling - TestPoolCache_Count - count tracking - TestPoolCache_Clear - full cache reset - Test_makeTokenPairKey - key consistency - Test_removePoolFromSlice - slice manipulation - 100% code coverage Features: - O(1) lookups for address, token pair, protocol - Automatic index synchronization - Thread-safe concurrent access - Defensive programming (copies, validation) - Comprehensive error handling Task: P3-001 through P3-005 Cache Implementation ✅ Complete Coverage: 100% (enforced) Performance: All operations O(1) or O(n log n) for sorting Next: Validation implementation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> |

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) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> |

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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> |
