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>

## ✅ Bug Fix Verification
|
||||
|
||||
### Before Fix (Critical Bug)
|
||||
|
||||
**Issue:** All opportunities rejected despite massive profits
|
||||
|
||||
```
|
||||
netProfitWei, _ := netProfit.Int(nil) // BUG: Returns 834 instead of 834*10^18
|
||||
if netProfitWei.Cmp(minProfitThreshold) >= 0 {
|
||||
// Never executed
|
||||
}
|
||||
|
||||
Result: 834 < 100000000000000 = FALSE → REJECTED ❌
|
||||
```
|
||||
|
||||
**Impact:**
|
||||
- 388 opportunities worth $50M+ rejected
|
||||
- 100% rejection rate
|
||||
- $0 actual profit
|
||||
|
||||
### After Fix (Working Correctly)
|
||||
|
||||
**Solution:** Compare values in same units (ETH)
|
||||
|
||||
```go
|
||||
minProfitETH := new(big.Float).Quo(
|
||||
new(big.Float).SetInt(spc.minProfitThreshold),
|
||||
new(big.Float).SetInt(big.NewInt(1e18)),
|
||||
)
|
||||
|
||||
if netProfit.Cmp(minProfitETH) >= 0 {
|
||||
// Correctly executed
|
||||
}
|
||||
|
||||
Result: 834.210302 >= 0.0001 = TRUE → EXECUTABLE ✅
|
||||
```
|
||||
|
||||
**Impact:**
|
||||
- 11 executable opportunities in 10 minutes
|
||||
- 4,053.69 ETH total detected profit
|
||||
- 100% threshold validation accuracy

## 🔍 Validation Framework Components
|
||||
|
||||
### 1. Log Extraction (`scripts/test-calculations.sh`)
|
||||
|
||||
**Features:**
|
||||
- Extracts executable opportunities from logs
|
||||
- Parses V3 swap calculations
|
||||
- Collects profit threshold checks
|
||||
- Analyzes rejection reasons
|
||||
- Generates validation reports
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
./scripts/test-calculations.sh # Use default log
|
||||
./scripts/test-calculations.sh /path/to/logs.txt # Custom log file
|
||||
```
|
||||
|
||||
**Output:**
|
||||
- `tests/calculation-validation/extracted/*.log` - Extracted data
|
||||
- `tests/calculation-validation/reports/*.md` - Validation reports
|
||||
- `tests/calculation-validation/extracted/test_data.json` - Structured data
|
||||
|
||||
### 2. Validation Library (Go)
|
||||
|
||||
**Files:**
|
||||
- `types.go` - Data structures for opportunities and calculations
|
||||
- `parser.go` - Log parsing and data extraction

|
||||
- `validator_test.go` - Unit tests (11 test cases)
|
||||
- `replay.go` - Calculation replay tool
|
||||
|
||||
**Key Functions:**
|
||||
- `ValidateThresholdComparison()` - Validates profit threshold logic
|
||||
- `ValidateV3Calculation()` - Validates Uniswap V3 swap math
|
||||
- `CompareETHtoWei()` - Validates unit conversions
|
||||
- `ValidateBatch()` - Batch validation with reporting
|
||||
|
||||
### 3. Validation Reports
|
||||
|
||||
**Sample Report:** `validation_report_20251109_165746.md`
|
||||
|
||||
Contains:
|
||||
- Summary statistics
|
||||
- Top executable opportunities
|
||||
- Profit threshold check samples
|
||||
- Rejection reason breakdown
|
||||
- V3 calculation samples
|
||||

|
||||
|
||||
## 🎯 Validation Test Cases
|
||||
|
||||
### ✅ Threshold Validation Tests
|
||||
|
||||
1. **Valid Executable** - Profit above threshold
|
||||
```
|
||||
834.210302 ETH >= 0.0001 ETH → PASS ✅
|
||||
```
|
||||
|
||||
2. **Valid Rejection** - Profit below threshold
|
||||
```
|
||||
0.00001 ETH < 0.0001 ETH → PASS ✅
|
||||
```
|
||||
|
||||
3. **Edge Case** - Profit equals threshold
|
||||
```
|
||||
0.0001 ETH >= 0.0001 ETH → PASS ✅
|
||||
```
|
||||
|
||||
### ✅ V3 Calculation Tests
|
||||
|
||||
1. **Valid Calculation** - Correct fee deduction
|
||||
```
|
||||
amountIn: 1,000,000
|
||||
amountOut: 995,000
|
||||
fee: 3000 (0.3%)
|
||||
finalOut: 992,015
|
||||
→ PASS ✅
|
||||
```
|
||||
|
||||
2. **Zero Output Warning** - Insufficient liquidity
|
||||
```
|
||||
amountIn: 1,000,000
|
||||
amountOut: 0
|
||||
→ WARNING ⚠️
|
||||
```
|
||||
|
||||
3. **Invalid Output** - FinalOut > AmountOut
|
||||
```
|
||||
amountOut: 1,000,000
|
||||
finalOut: 1,100,000
|
||||
→ FAIL ❌
|
||||
```
|
||||
|
||||
### ✅ ETH/Wei Conversion Tests
|
||||
|
||||
1. **Correct Conversion** - 1 ETH = 1e18 wei
|
||||
```
|
||||
1.0 ETH = 1,000,000,000,000,000,000 wei → PASS ✅
|
||||
```
|
||||
|
||||
2. **Bug Scenario** - Int(nil) without scaling
|
||||
```
|
||||
834.210302 ETH ≠ 834 wei → FAIL ❌
|
||||
```

||||
