+```
+
+## 🔒 Security
+
+### Core Invariants
+
+Every transaction must satisfy:
+- Debt never increases
+- Collateral never decreases
+- Health factor never worsens
+- LTV never worsens
+
+### Audit Status
+
+⚠️ **Unaudited** - This code is unaudited. Use at your own risk.
+
+For production deployments:
+1. Complete security audit
+2. Start with conservative parameters
+3. Monitor closely
+4. Have emergency pause ready
+
+## 📊 Monitoring
+
+### Events
+
+Monitor these events:
+- `AmortizationExecuted`: Successful cycle
+- `InvariantFail`: Invariant violation
+- `PositionSnapshot`: Position change
+- `CollateralAdded`: Collateral increase
+- `DebtRepaid`: Debt decrease
+
+### Metrics
+
+Track:
+- Health factor trends
+- Flash loan execution rates
+- Policy denial rates
+- Gas costs
+- Position size

+# DBIS System Architecture
+
+## Overview
+
+The DBIS (Debt-Based Institutional Strategy) system is a comprehensive DeFi leverage management platform that implements atomic amortizing cycles to improve position health while maintaining strict invariants.
+
+## Core Principles
+
+### 1. Amortization Rule
+Every atomic transaction MUST end with:
+- **Debt ↓** (decreased)
+- **Collateral ↑** (increased)
+- **LTV ↓** (decreased loan-to-value ratio)
+- **HF ↑** (improved health factor)
+
+If any of these conditions fail, the transaction reverts.
+
+### 2. Policy Controls Over Bot Intelligence
+- Bots suggest actions
+- **Contracts enforce invariants**
+- If invariant fails → revert → no risk
+
+### 3. Single Identity
+- One vault address
+- One router
+- One kernel
+- Multisig/MPC owner
+- Zero opacity
+- Maximum governance safety
+
+### 4. Modular & Upgradeable
+All components are swappable:
+- Router
+- Kernel
+- Policy modules
+- Providers
+- Oracle adapters
+
+## System Components
+
+### Core Contracts
+
+1. **DBISInstitutionalVault.sol**
+   - Tracks collateral and debt across multiple assets
+   - Integrates with Aave v3 for position data
+   - Enforces position invariants
+
+2. **FlashLoanRouter.sol**
+   - Aggregates flash loans from multiple providers:
+     - Aave v3
+     - Balancer Vault
+     - Uniswap V3
+     - DAI Flash Mint
+   - Liquidity-weighted provider selection
+
+3. **RecursiveLeverageKernel.sol**
+   - Implements atomic amortizing cycle pipeline:
+     1. Harvest yield
+     2. Swap to stable/collateral
+     3. Split: repay debt + add collateral
+     4. Enforce invariants
+     5. Revert if LTV worsens
+
+4. **CollateralToggleManager.sol**
+   - Manages Aave v3 collateral enable/disable
+   - Batch operations for efficiency
+
+### Governance Contracts
+
+5. **ConfigRegistry.sol**
+   - Stores all system parameters:
+     - Max loops
+     - Max flash size per asset
+     - Min/Target health factor
+     - Allowed assets
+     - Provider caps
+
+6. **PolicyEngine.sol**
+   - Plugin architecture for policy modules
+   - Aggregates policy decisions
+   - All modules must approve
+
+7. **GovernanceGuard.sol**
+   - Final gatekeeper for all actions
+   - Invariant validation
+   - Strategy throttling
+
+8. **Policy Modules**
+   - **PolicyHFTrend**: Monitors health factor trends
+   - **PolicyFlashVolume**: Limits flash loan volume per period
+   - **PolicyLiquiditySpread**: Validates liquidity spreads
+   - **PolicyProviderConcentration**: Prevents over-concentration
+
+### Oracle Layer
+
+9. **DBISOracleAdapter.sol**
+   - Standardizes pricing from multiple sources:
+     - Aave oracles
+     - Chainlink price feeds
+     - Uniswap TWAPs
+   - Aggregates with confidence scoring
+
+## Execution Flow
+
+### Atomic Amortizing Cycle
+
+```
+1. Kernel.executeAmortizingCycle()
+   ↓
+2. GovernanceGuard.enforceInvariants()
+   ↓
+3. Vault.snapshotPosition()
+   ↓
+4. FlashRouter.flashLoan()
+   ↓
+5. Kernel.onFlashLoan() callback:
+   - Harvest yield
+   - Swap to target asset
+   - Repay debt
+   - Add collateral
+   ↓
+6. Vault.verifyPositionImproved()
+   ↓
+7. If invariant fails → revert
+   If invariant passes → emit events
+```
+
+## Security Model
+
+### Invariant Enforcement
+
+All position changes must satisfy:
+- `debtAfter <= debtBefore`
+- `collateralAfter >= collateralBefore`
+- `healthFactorAfter >= healthFactorBefore`
+
+### Access Control
+
+- **Owner**: Full administrative control
+- **Operator**: Can execute amortization cycles
+- **Kernel Role**: Can record position changes
+- **Policy Modules**: Evaluated by PolicyEngine
+
+### Upgradeability
+
+- All core contracts support UUPS upgradeability
+- Policy modules are plugin-based
+- Provider addresses are configurable
+
+## Integration Points
+
+### Aave v3
+- Position data
+- Collateral management
+- Borrowing/repayment
+
+### Flash Loan Providers
+- Aave v3 Pool
+- Balancer Vault
+- Uniswap V3 Pools
+- DAI Flash Mint
+
+### DEXs
+- Uniswap V3 Router (swaps)
+
+### Oracles
+- Chainlink Price Feeds
+- Aave Oracle
+- Uniswap TWAPs
+
+## Multi-Chain Support
+
+The system is designed for multi-chain deployment:
+- Primary: Ethereum Mainnet
+- Secondary: Arbitrum, Polygon, Base, Optimism
+
+Each chain requires:
+- Chain-specific protocol addresses
+- Chain-specific oracle feeds
+- Chain-specific RPC endpoints
+

+# Atomic Amortizing Cycle
+
+## Overview
+
+The atomic amortizing cycle is the core mechanism of the DBIS system. It guarantees that every execution improves the position (debt↓, collateral↑, LTV↓, HF↑) in a single atomic transaction.
+
+## Cycle Phases
+
+### Phase 1: Pre-Execution Validation
+```
+GovernanceGuard.enforceInvariants()
+  ↓
+PolicyEngine.evaluateAll()
+  ↓
+ConfigRegistry.getMaxLoops()
+  ↓
+Vault.snapshotPosition()
+```
+
+**Checks:**
+- Policy modules approve action
+- Max loops not exceeded
+- Position snapshot taken
+
+### Phase 2: Flash Loan Execution
+```
+FlashLoanRouter.flashLoan()
+  ↓
+Provider-specific flash loan (Aave/Balancer/Uniswap/DAI)
+  ↓
+Kernel.onFlashLoan() callback
+```
+
+**Actions:**
+- Borrow flash loan amount
+- Execute callback with borrowed funds
+
+### Phase 3: Amortization Operations
+```
+onFlashLoan() callback:
+  1. Harvest yield (if available)
+  2. Swap to target asset
+  3. Split funds:
+     - 50% repay debt
+     - 50% add collateral
+  4. Repay flash loan (principal + fee)
+```
+
+**Math:**
+```
+yieldAmount = harvestYield()
+totalAmount = flashAmount + yieldAmount
+swapAmount = swapToTargetAsset(totalAmount)
+debtRepayment = swapAmount / 2
+collateralAddition = swapAmount - debtRepayment
+```
+
+### Phase 4: Invariant Verification
+```
+Vault.verifyPositionImproved(
+  collateralBefore,
+  debtBefore,
+  healthFactorBefore
+)
+```
+
+**Checks:**
+- `debtAfter < debtBefore` ✓
+- `collateralAfter > collateralBefore` ✓
+- `healthFactorAfter > healthFactorBefore` ✓
+
+### Phase 5: Completion
+```
+If invariants pass:
+  - Emit AmortizationExecuted event
+  - Return success
+If invariants fail:
+  - Emit InvariantFail event
+  - Revert transaction
+```
+
+## Recursive Cycles
+
+The kernel can execute multiple cycles in sequence:
+
+```solidity
+for (uint256 i = 0; i < maxLoops; i++) {
+    executeSingleStep();
+    
+    // Early exit if target achieved
+    if (currentHF >= targetHF) {
+        break;
+    }
+    
+    // Early exit if no improvement
+    if (noImprovement) {
+        break;
+    }
+}
+```
+
+Each cycle must improve the position independently.
+
+## Example Flow
+
+### Input
+- Current Position:
+  - Collateral: $1,000,000
+  - Debt: $800,000
+  - HF: 1.05
+  - LTV: 80%
+
+### Cycle Execution
+1. Flash loan: $100,000 USDC
+2. Swap: $100,000 → $100,000 USDC (no swap needed)
+3. Repay debt: $50,000
+4. Add collateral: $50,000
+
+### Output
+- New Position:
+  - Collateral: $1,050,000 (+$50,000)
+  - Debt: $750,000 (-$50,000)
+  - HF: 1.12 (+0.07)
+  - LTV: 71.4% (-8.6%)
+
+### Invariant Check
+- ✓ Debt decreased
+- ✓ Collateral increased
+- ✓ HF improved
+- ✓ LTV decreased
+
+**Result: SUCCESS**
+
+## Gas Optimization
+
+### Batch Operations
+- Multiple cycles in one transaction
+- Batch collateral toggles
+- Batch policy evaluations
+
+### Flash Loan Optimization
+- Use cheapest provider (DAI flash mint = 0% fee)
+- Split across providers for large amounts
+- Optimal provider selection
+
+### Early Exits
+- Exit if target HF achieved
+- Exit if no improvement possible
+- Exit if max loops reached
+
+## Error Handling
+
+### Revert Conditions
+1. Policy check fails
+2. Flash loan unavailable
+3. Swap fails (slippage too high)
+4. Debt repayment fails
+5. Invariant check fails
+
+### Recovery
+All state changes are atomic. On revert:
+- Flash loan not borrowed (or automatically repaid)
+- Position unchanged
+- Can retry with different parameters
+
+## Monitoring
+
+### Events Emitted
+- `AmortizationExecuted(cyclesExecuted, collateralIncrease, debtDecrease, hfImprovement)`
+- `InvariantFail(reason)`
+- `SingleStepCompleted(collateralAdded, debtRepaid)`
+
+### Metrics Tracked
+- Cycles executed per transaction
+- Average HF improvement per cycle
+- Gas cost per cycle
+- Success rate
+
+## Safety Guarantees
+
+1. **Atomicity**: All-or-nothing execution
+2. **Invariant Preservation**: Position always improves
+3. **Reversibility**: Can revert at any point
+4. **Policy Compliance**: All policies must approve
+5. **Access Control**: Only authorized operators

+# System Invariants
+
+## Core Invariants
+
+The DBIS system enforces strict invariants that **must** be maintained at all times. These invariants are checked on-chain and any violation causes transaction reversion.
+
+## Position Invariants
+
+### 1. Debt Never Increases
+```
+debtAfter <= debtBefore
+```
+After any amortization cycle, total debt value must never increase.
+
+### 2. Collateral Never Decreases
+```
+collateralAfter >= collateralBefore
+```
+After any amortization cycle, total collateral value must never decrease.
+
+### 3. Health Factor Never Worsens
+```
+healthFactorAfter >= healthFactorBefore
+```
+Health factor must always improve or stay the same.
+
+### 4. LTV Never Worsens
+```
+LTV_after <= LTV_before
+```
+Loan-to-value ratio must never increase.
+
+## Combined Invariant Check
+
+All position invariants are checked together in `Vault.verifyPositionImproved()`:
+
+```solidity
+bool debtDecreased = debtAfter < debtBefore;
+bool collateralIncreased = collateralAfter > collateralBefore;
+bool hfImproved = healthFactorAfter > healthFactorBefore;
+
+// All three must improve for strict amortization
+return debtDecreased && collateralIncreased && hfImproved;
+```
+
+## Policy Invariants
+
+### Flash Volume Limits
+- Flash loan volume per asset per period ≤ configured limit
+- Global flash loan volume per period ≤ configured limit
+
+### Health Factor Thresholds
+- Current HF ≥ minimum HF (from ConfigRegistry)
+- HF improvement ≥ minimum improvement (for amortization)
+
+### Provider Concentration
+- No single provider can exceed maximum concentration percentage
+- Diversification across providers enforced
+
+### Liquidity Spreads
+- Swap spreads ≤ maximum acceptable spread
+- Liquidity depth ≥ minimum required depth
+
+## Invariant Enforcement Points
+
+1. **Pre-Execution**: GovernanceGuard verifies policy invariants
+2. **During Execution**: Kernel enforces position changes
+3. **Post-Execution**: Vault verifies position improvement
+4. **On Revert**: All state changes rolled back
+
+## Testing Invariants
+
+### Unit Tests
+- Test each invariant in isolation
+- Test invariant violations cause reversion
+
+### Integration Tests
+- Test full cycles maintain invariants
+- Test edge cases
+
+### Fuzz Tests
+- Random inputs verify invariants hold
+- Stress test boundary conditions
+
+### Invariant Tests (Foundry)
+- Continuous invariant checking
+- Property-based testing
+
+## Failure Modes
+
+### Invariant Violation Detection
+When an invariant is violated:
+1. Transaction reverts
+2. Event emitted: `InvariantFail(reason)`
+3. State unchanged (all changes rolled back)
+4. MEV bot alerted
+
+### Recovery Procedures
+1. Analyze reason for failure
+2. Adjust parameters if needed
+3. Re-run with corrected parameters
+4. Verify invariants before next cycle
+
+## Formal Verification
+
+Future work:
+- Formal verification of invariant preservation
+- Mathematical proofs of correctness
+- Certified invariant checks

+# MEV Bot Documentation
+
+## Overview
+
+The DBIS MEV Bot is a TypeScript application that monitors positions and executes profitable atomic amortization cycles, arbitrage opportunities, and protective deleveraging.
+
+## Architecture
+
+### Core Components
+
+1. **Bot Engine** (`bot.ts`)
+   - Main event loop
+   - Strategy coordination
+   - Opportunity detection
+
+2. **Strategies**
+   - **Amortization**: Executes amortization cycles
+   - **Arbitrage**: Finds arbitrage opportunities
+   - **Deleverage**: Protects positions with low HF
+
+3. **Utilities**
+   - **Invariant Checker**: Verifies invariants before execution
+   - **Position Calculator**: Calculates position metrics
+   - **Bundle Builder**: Builds Flashbots bundles
+
+4. **Providers**
+   - **Flash Router Client**: Interacts with FlashLoanRouter
+   - **Aave Client**: Reads Aave position data
+   - **Uniswap Client**: Executes swaps
+
+## Setup
+
+### 1. Install Dependencies
+
+```bash
+cd mev-bot
+npm install
+```
+
+### 2. Configure Environment
+
+Create `.env` in `mev-bot/`:
+
+```env
+RPC_URL=https://eth-mainnet.g.alchemy.com/v2/YOUR_KEY
+PRIVATE_KEY=your_bot_private_key
+FLASH_ROUTER_ADDRESS=0x...
+VAULT_ADDRESS=0x...
+KERNEL_ADDRESS=0x...
+AAVE_POOL_ADDRESS=0x...
+UNISWAP_ROUTER_ADDRESS=0x...
+```
+
+### 3. Build
+
+```bash
+npm run build
+```
+
+### 4. Run
+
+```bash
+npm start
+```
+
+## Strategies
+
+### Amortization Strategy
+
+**Purpose**: Execute profitable amortization cycles
+
+**Detection**:
+1. Check current position
+2. Calculate potential improvement
+3. Estimate gas costs
+4. Determine profitability
+
+**Execution**:
+1. Verify invariants
+2. Build transaction
+3. Submit via Flashbots (if enabled)
+4. Monitor execution
+
+### Arbitrage Strategy
+
+**Purpose**: Find arbitrage opportunities
+
+**Detection**:
+1. Compare prices across DEXs
+2. Calculate potential profit
+3. Account for gas and fees
+4. Determine if profitable
+
+**Execution**:
+1. Execute arbitrage trade
+2. Capture profit
+3. Update position
+
+### Deleverage Strategy
+
+**Purpose**: Protect position when HF is low
+
+**Trigger**: Health factor < 1.10
+
+**Action**:
+1. Reduce leverage
+2. Improve health factor
+3. Prevent liquidation risk
+
+## Bundle Building
+
+### Flashbots Integration
+
+For private transaction submission:
+
+```typescript
+import { FlashbotsBundleProvider } from "@flashbots/ethers-provider-bundle";
+
+const bundle = await bundleBuilder.buildBundle(transactions);
+await flashbotsProvider.sendBundle(bundle, targetBlockNumber);
+```
+
+### Benefits
+- No front-running
+- Atomic execution
+- Priority inclusion
+
+## Monitoring
+
+### Position Monitoring
+
+```typescript
+const position = await positionCalculator.getPosition();
+console.log(`HF: ${position.healthFactor}`);
+console.log(`LTV: ${position.ltv}`);
+console.log(`Collateral: ${position.collateral}`);
+console.log(`Debt: ${position.debt}`);
+```
+
+### Alert Conditions
+
+- Health factor < 1.10
+- Position at risk
+- Policy denial
+- Transaction failure
+- Bot downtime
+
+## Multi-Region Deployment
+
+Deploy in multiple regions for redundancy:
+- US East
+- EU
+- Singapore
+
+Use leader election or load balancing.
+
+## Configuration
+
+### Poll Interval
+Adjust how often bot checks for opportunities:
+```typescript
+private pollInterval = 5000; // 5 seconds
+```
+
+### Profitability Thresholds
+Minimum profit to execute:
+```typescript
+const minProfit = ethers.parseEther("0.01"); // 0.01 ETH
+```
+
+### Gas Price Management
+Set max gas price:
+```typescript
+const maxGasPrice = ethers.parseUnits("100", "gwei");
+```
+
+## Error Handling
+
+### Retry Logic
+```typescript
+async executeWithRetry(operation, maxRetries = 3) {
+    for (let i = 0; i < maxRetries; i++) {
+        try {
+            return await operation();
+        } catch (error) {
+            if (i === maxRetries - 1) throw error;
+            await sleep(1000 * (i + 1)); // Exponential backoff
+        }
+    }
+}
+```
+
+### Failure Notifications
+Send alerts on:
+- Transaction failures
+- Invariant violations
+- Policy denials
+- Bot crashes
+
+## Logging
+
+Use Winston for structured logging:
+
+```typescript
+import winston from "winston";
+
+const logger = winston.createLogger({
+    level: "info",
+    format: winston.format.json(),
+    transports: [
+        new winston.transports.File({ filename: "error.log", level: "error" }),
+        new winston.transports.File({ filename: "combined.log" })
+    ]
+});
+```
+
+## Performance Optimization
+
+1. **Batch Operations**: Group multiple checks
+2. **Caching**: Cache position data
+3. **Async Processing**: Parallel opportunity detection
+4. **Connection Pooling**: Reuse RPC connections
+
+## Security
+
+1. **Private Key Management**: Use secure key storage
+2. **Access Control**: Limit bot permissions
+3. **Rate Limiting**: Prevent spam
+4. **Monitoring**: Track all bot actions
+
+## Deployment
+
+### Docker
+
+```dockerfile
+FROM node:18
+WORKDIR /app
+COPY package*.json ./
+RUN npm install
+COPY . .
+CMD ["npm", "start"]
+```
+

+# Policy System
+
+## Overview
+
+The policy system provides modular, plugin-based governance controls. Policy modules evaluate proposed actions and can approve or deny them.
+
+## Policy Architecture
+
+### PolicyEngine
+Central coordinator that:
+- Registers policy modules
+- Aggregates decisions from all modules
+- Returns allow/deny with reason
+
+### Policy Modules
+
+#### 1. PolicyHFTrend
+Monitors health factor trends and ensures:
+- HF never decreases
+- HF improvements meet minimum threshold
+- Trend is always improving
+
+**Configuration:**
+- `minHFThreshold`: Minimum acceptable HF (default: 1.05)
+- `minHFImprovement`: Minimum improvement per cycle (default: 1%)
+
+#### 2. PolicyFlashVolume
+Limits flash loan volume per time period:
+- Per-asset volume limits
+- Global volume limits
+- Time-based tracking windows
+
+**Configuration:**
+- `periodDuration`: Tracking window (default: 1 day)
+- `assetVolumeLimit[asset]`: Per-asset limit
+- `globalVolumeLimit`: Global limit
+
+#### 3. PolicyLiquiditySpread
+Validates liquidity and spreads:
+- Maximum acceptable spread
+- Minimum liquidity depth
+- Liquidity-to-operation ratio checks
+
+**Configuration:**
+- `maxSpreadBps`: Maximum spread in basis points (default: 50 = 0.5%)
+- `minLiquidityDepth[asset]`: Minimum liquidity required
+
+#### 4. PolicyProviderConcentration
+Prevents over-concentration in single providers:
+- Maximum percentage from single provider
+- Diversification enforcement
+- Time-window tracking
+
+**Configuration:**
+- `maxProviderConcentrationBps`: Maximum concentration (default: 5000 = 50%)
+- `trackingWindow`: Tracking period (default: 7 days)
+
+## Policy Evaluation Flow
+
+```
+Action Proposed
+  ↓
+PolicyEngine.evaluateAll(actionType, actionData)
+  ↓
+For each registered module:
+  1. Check if enabled
+  2. Call module.evaluate()
+  3. Get decision
+  4. If deny → return deny immediately
+  ↓
+If all modules approve → return allow
+```
+
+## Policy Decision Structure
+
+```solidity
+struct PolicyDecision {
+    bool allowed;
+    string reason;  // Empty if allowed, explanation if denied
+}
+```
+
+## Adding New Policy Modules
+
+### Step 1: Implement IPolicyModule
+
+```solidity
+contract MyPolicyModule is IPolicyModule {
+    function evaluate(
+        bytes32 actionType,
+        bytes memory actionData
+    ) external view returns (PolicyDecision memory) {
+        // Policy logic
+        return PolicyDecision({
+            allowed: true,
+            reason: ""
+        });
+    }
+    
+    function name() external pure returns (string memory) {
+        return "MyPolicy";
+    }
+    
+    function isEnabled() external view returns (bool) {
+        return _enabled;
+    }
+    
+    function setEnabled(bool enabled) external onlyOwner {
+        _enabled = enabled;
+    }
+}
+```
+
+### Step 2: Register with PolicyEngine
+
+```solidity
+policyEngine.registerPolicyModule(address(myPolicyModule));
+```
+
+### Step 3: Configure Parameters
+
+```solidity
+myPolicyModule.setParameter(value);
+```
+
+## Policy Enforcement
+
+### Pre-Execution
+- GovernanceGuard calls `PolicyEngine.evaluateAll()`
+- If denied, transaction reverts before execution
+
+### During Execution
+- Some policies monitor state during execution
+- Can emit warnings or deny mid-execution
+
+### Post-Execution
+- Policies can verify outcomes
+- Can trigger alerts if thresholds exceeded
+
+## Configuration Management
+
+### Owner-Only Updates
+- Register/unregister modules
+- Configure policy parameters
+- Enable/disable modules
+
+### Multi-Sig Requirements
+Critical policy changes should require multi-sig:
+- Adding new policy modules
+- Changing volume limits
+- Changing HF thresholds
+
+## Testing Policies
+
+### Unit Tests
+- Test each policy module independently
+- Test allow/deny scenarios
+- Test configuration updates
+
+### Integration Tests
+- Test policy aggregation
+- Test policy conflicts
+- Test policy order independence
+
+## Best Practices
+
+1. **Fail-Safe Defaults**: Deny by default if policy unavailable
+2. **Clear Reasons**: Provide detailed denial reasons
+3. **Modular Design**: Keep policies independent
+4. **Upgradeable**: Support parameter updates
+5. **Documented**: Document all policy logic
+
+## Monitoring
+
+### Policy Metrics
+- Approval/denial rates
+- Most common denial reasons
+- Policy evaluation latency
+- Module usage statistics
+
+### Alerts
+- High denial rate
+- Policy module failures
+- Unusual policy patterns

+### 1. Core Functionality Tests
+
+#### Vault Tests
+```solidity
+function test_RecordCollateralAdded() public {
+    // Test collateral recording
+}
+
+function test_RecordDebtRepaid() public {

+function test_ExecuteAmortizingCycleRevertsIfInvariantFails() public {
+    // Test invariant enforcement
+}
+```
+
+### 2. Invariant Tests
+
+Foundry invariant tests ensure invariants hold:
+
+```solidity
+function invariant_HealthFactorNeverDecreases() public {
+    // HF must never decrease
+}
+
+function invariant_DebtNeverIncreases() public {
+    // Debt must never increase
+}
+

+    // Collateral must never decrease
+}
+```
+
+Run invariant tests:
+```bash
+forge test --match-test invariant
+```
+
+### 3. Fuzz Tests
+
+Random input testing to find edge cases:
+
+```solidity
+function testFuzz_ExecuteCycleWithRandomAmounts(
+    uint256 flashAmount,
+    uint256 yieldAmount
+) public {
+    // Fuzz with random amounts
+    // Ensure invariants hold
+}
+```
+
+Run fuzz tests:
+```bash
+forge test --match-test testFuzz
+```
+
+### 4. Fork Tests
+
+Test against mainnet state:
+
+```bash
+forge test --fork-url $RPC_URL
+```
+
+## Test Utilities
+
+### Helpers
+
+Create test helpers in `test/helpers/`:
+
+```solidity
+contract TestHelpers {
+    function deployMockAavePool() internal returns (address) {
+        // Deploy mock
+    }
+    
+    function createPosition(uint256 collateral, uint256 debt) internal {
+        // Setup test position
+    }
+}
+```
+
+### Mocks
+
+Mock external contracts:
+- Mock Aave Pool
+- Mock Oracle
+- Mock Uniswap Router
+
+## Test Scenarios
