-## Implementation Steps
-
-### Phase 1: Core Infrastructure 
-1. **Project Setup**
-   - Initialize Anchor project structure
-   - Define state accounts (Config, CollateralConfig, Position, LendingVault)
-   - Create custom error types
-   - Set up test environment
-
-2. **Basic Instructions**
-   - `initialize` - Set up global protocol config (authority, pause state)
-   - `register_collateral` - Register new collateral types with risk parameters
-   - `deposit_collateral` - Accept deposits for any enabled collateral
-   - Base account validation and PDA derivation
-
-### Phase 2: Position Management
-3. **Open Position Logic**
-   - `open_position` - Create leveraged DLMM position
-   - Integrate mock lending vault for borrowing
-   - CPI to Meteora DLMM to create LP position
-   - Store position reference and debt tracking
-
-4. **Close Position Logic**
-   - `close_position` - Unwind position voluntarily
-   - CPI to Meteora to remove liquidity
-   - Repay debt to lending vault
-   - Return remaining collateral to user
-
-### Phase 3: Risk Management
-5. **Health Monitoring**
-   - Integrate price oracle (Pyth/Switchboard/magicblock)
-   - Implement health factor calculation
-   - LTV calculation based on collateral value vs debt
-
-6. **Liquidation System**
-   - `liquidate` - Force-close unhealthy positions
-   - Health check validation
-   - Liquidator incentive distribution
-   - Bad debt handling
-
-### Phase 4: Testing & Refinement
-7. **Comprehensive Testing**
-   - Unit tests for all instructions
-   - Integration tests with Meteora devnet
-   - Liquidation scenario testing
-   - Oracle edge case handling
-
-8. **Security Hardening**
-   - Reentrancy protection
-   - Oracle staleness checks
-   - Overflow/underflow validation
-   - Access control verification
-
-## Key Technical Challenges
-
-### 1. **Meteora DLMM Integration**
-- **Challenge**: CPI to Meteora to create/close DLMM positions
-- **Solution**: Study Meteora SDK and program interface, implement proper account passing
-
-### 2. **Health Factor Calculation**
-- **Challenge**: Accurately value DLMM position + account for impermanent loss
-- **Solution**: Oracle-based collateral pricing, conservative LTV ratios
-
-### 3. **Debt Accounting**
-- **Challenge**: Track borrowed amounts and interest accrual
-- **Solution**: Simple interest model in POC, store principal + timestamp
-
-### 4. **Liquidation Mechanics**
-- **Challenge**: Ensure liquidations are profitable and timely
-- **Solution**: Clear threshold + liquidator incentives, anyone can liquidate
-
-### 5. **Oracle Integration**
-- **Challenge**: Reliable price feeds for SOL/USDC
-- **Solution**: Pyth oracle integration with staleness checks
-
-## User Stories (POC Scope)
-
-### Experienced Solana LP
-- **Deposit collateral** - Deposit SOL or USDC to open positions
-- **Open leveraged position** - Create DLMM LP with borrowed funds
-- **View position status** - Check health factor and liquidation risk
-- **Close position** - Exit position, repay debt, withdraw collateral
-
-### Liquidator / Keeper
-- **Check position health** - Monitor positions for liquidation
-- **Force-close unsafe positions** - Liquidate unhealthy positions for reward
+### Instruction Flow
+
+**Open Position**
+1. User deposits SOL collateral into PDA vault (`["vault", owner, mint]`)
+2. Protocol checks LTV against oracle price
+3. Borrows wSOL from lending vault (updates `total_borrowed`)
+4. CPI to Meteora DLMM: creates position and adds one-sided wSOL liquidity
+5. Records debt and DLMM position reference on `Position` account
+
+**Close Position**
+1. CPI to Meteora DLMM: removes all liquidity and closes position
+2. If LP received non-wSOL token (token X), swaps it back to wSOL via DLMM
+3. If proceeds >= debt: repay debt, send surplus to user's wSOL ATA
+4. If proceeds < debt: cover shortfall from user's collateral vault (native SOL -> wSOL via `sync_native`)
+5. Marks position as `Closed`
+
+**Liquidation**
+1. Anyone can call `liquidate` on a position where LTV > `liquidation_threshold`
+2. CPI to Meteora DLMM: removes all liquidity and closes position
+3. LP proceeds repay debt to lending vault
+4. Liquidation penalty (% of collateral) sent to liquidator as native SOL
+5. Remaining collateral returned to position owner
+6. Marks position as `Liquidated`

+  - Rejects liquidation of healthy position
+
+Protocol Config (20 tests)
+  - Initialization, collateral registration, risk param validation
+  - Deposit collateral, pause/unpause, config updates
+  - Multiple positions per user
+
+Mock Oracle (6 tests)
+  - Initialize, update price, timestamp refresh, auth checks
+
+Open Position (5 tests)
+  - Opens 2x leveraged DLMM position with wSOL
+  - Verifies DLMM position has liquidity via SDK

+## Known Limitations (V1)
+
+### Static LTV / Health Check
+
+The current health check uses the **static collateral and debt amounts** recorded at position open time. Since both collateral and debt are denominated in SOL, oracle price changes cancel out and do not affect the LTV ratio.
+
+In reality, the DLMM position value can diverge from the original debt:
+- **Price moves through the position's bins** → SOL gets swapped to the paired token (impermanent loss)
+- **On close/liquidation**, the LP proceeds may be less than the original borrowed amount
+- The protocol handles this correctly at settlement (bad debt absorption, shortfall from collateral), but the **health check cannot detect it in advance**
+
+**V2 fix**: Compute dynamic health by reading the DLMM position's bin shares on-chain and calculating their current SOL-equivalent value against the outstanding debt. This requires cross-program reads of Meteora's position and bin array accounts.
+
+### Same-Asset Collateral and Debt
+
+V1 uses SOL as both collateral and borrowed asset. This means:
+- LTV is fixed at open time and never changes from market movements
+- Liquidation can only be triggered by admin threshold changes or DLMM position value loss (which isn't tracked)
+
+**V2 fix**: Support cross-asset collateral (e.g., deposit USDC, borrow SOL). When SOL price rises, debt value increases relative to collateral, naturally pushing LTV up and enabling market-driven liquidations.
+
+## Future Enhancements (V2+)
+
+### Health & Risk
+- Dynamic health factor based on live DLMM position value
+- Cross-asset collateral (USDC, mSOL, jitoSOL)
+- Real oracle integration (Pyth, Switchboard)
+- Partial liquidations

+### Yield & Capital Efficiency
