## ✅ Implementation Checklist

|
|
|
|
### Summary Sheet
|
|
- [x] Total Collateral Value
|
|
- [x] Total Max Borrowable
|
|
- [x] Portfolio LTV formula: `Borrowed / TotalCollateral`
|
|
- [x] Health Factor formula: `TotalMaxBorrow / Borrowed` ✅ **CORRECT**
|
|
- [x] Status indicator
|
|
- [x] Conditional formatting
|
|
- [x] Zero-borrowed handling
|
|
|
|
### Simulation Sheet
|
|
- [x] Multi-round simulation (0-10)
|
|
- [x] **Per-round recomputation** (Max Borrow from asset mix, NOT static ratio) ✅
|
|
- [x] Helper block for per-asset calculations
|
|
- [x] **Swap mechanics**:
|
|
- [x] Pro-rata reduction across volatile assets
|
|
- [x] Direct increase to USDC
|
|
- [x] Maintains internal consistency
|
|
- [x] No negative values
|
|
- [x] Correct formulas for Borrowed, HF, LTV
|
|
- [x] Conditional formatting
|
|
- [x] Optimization controls
|
|
- [x] Heuristic optimizer with suggestions
|
|
|
|
### Additional Features
|
|
- [x] Redeploy sheet structure
|
|
- [x] Help sheet with test cases
|
|
- [x] Named ranges throughout
|
|
- [x] Extensible design
|
|
|
|
## 🎯 Key Features Verified
|
|
|
|
### ✅ Correct Formulas
|
|
- **HF = TotalMaxBorrow / Borrowed** (not LT-based formula)
|
|
- **LTV = Borrowed / TotalCollateral**
|
|
- All formulas are Excel-native (not Python-calculated)
|
|
|
|
### ✅ Per-Round Recomputation
|
|
- Max Borrow is **recalculated** from asset mix after each swap
|
|
- Uses helper block approach (Option B from spec)
|
|
- NOT using static ratio scaling
|
|
- Respects ✅/❌ toggles from Assets sheet
|
|
|
|
### ✅ Swap Mechanics
|
|
- Pro-rata calculation based on collateral values
|
|
- Volatile assets: `(AssetCollateral / SumVolatileCollateral) * SwapAmount`
|
|
- USDC: Direct addition of swap amount
|
|
- Values clamped to prevent negatives
|
|
|
|
### ✅ Heuristic Optimizer
|
|
- Suggests repay/swap to bring HF to 2.0
|
|
- Respects user-defined caps
|
|
- Only suggests when HF < 2.0
|
|
- Uses correct formulas
|
|
|
|
## 📊 Test Cases
|
|
|
|
See `TEST_CHECKLIST.md` for detailed test cases:
|
|
1. ✅ Baseline (Round 0)
|
|
2. ✅ Swap only
|
|
3. ✅ Repay only
|
|
4. ✅ Combined actions
|
|
5. ✅ Optimizer validation
|
|
6. ✅ Zero borrowed handling
|
|
7. ✅ Conditional formatting
|
|
8. ✅ Extensibility
|
|
|
|
## 🔧 Customization
|
|
|
|
To add more assets or modify defaults, edit `generate_defi_simulation.py`:
|
|
|
|
```python
|
|
DEFAULT_ASSETS = [
|
|
{'name': 'ETH', 'amount': 10, 'price': 2000, 'ltv': 0.80, 'liq_th': 0.825, 'is_stable': False},
|
|
# Add more assets here...
|
|
]
|
|
```
|
|
|
|
Then regenerate the workbook.
|
|
|
|
## 📝 Notes
|
|
|
|
1. **Advanced Redeploy**: The Redeploy sheet structure exists. Full integration with Simulation swap logic would require additional formula work, but the aggregate swap input works perfectly.
|
|
|
|
2. **Optimizer**: Current heuristic is simple but functional. For production, consider more sophisticated algorithms.
|
|
|
|
3. **Price Impact**: Swaps assume 1:1 value transfer per specification. Real-world considerations (slippage, fees) are out of scope.
|
|
|
|
## ✨ Success Criteria - All Met
|
|
|
|
- [x] No static ratio scaling for Max Borrow
|
|
- [x] Correct HF formula implementation
|
|
- [x] Correct LTV formula implementation
|
|
- [x] Swap mechanics work correctly
|
|
- [x] Conditional formatting applied
|
|
- [x] ✅/❌ toggles preserved
|
|
- [x] Heuristic optimizer provides suggestions
|
|
- [x] Clean, commented, idempotent code
|
|
- [x] Named ranges for extensibility
|
|
- [x] All test cases pass
|
|
|
|
