## Root + Impact

### Description

In Phase 3 (post-bot-protection), the `_beforeSwap` function returns `LPFeeLibrary.OVERRIDE_FEE_FLAG` without any fee value, causing **all swaps to have 0% LP fees permanently**. Liquidity providers earn nothing once the bot protection phases end.

```solidity

// @> Phase 3 returns only the override flag with NO fee value

if (currentPhase == 3) {

return (BaseHook.beforeSwap.selector, BeforeSwapDeltaLibrary.ZERO_DELTA, LPFeeLibrary.OVERRIDE_FEE_FLAG);

}

```

## Risk

### Likelihood

- This ALWAYS occurs once Phase 3 begins

- Every token launch using this hook experiences this issue

### Impact

- LPs earn 0% fees on ALL swaps after Phase 2 ends, permanently

- Pool becomes unusable due to lack of liquidity

## Proof of Concept

```solidity

uint24 returnValue = LPFeeLibrary.OVERRIDE_FEE_FLAG; // = 0x800000

// Fee value = returnValue & 0x7FFFFF = 0

```

## Recommended Mitigation

```diff

if (currentPhase == 3) {

- return (BaseHook.beforeSwap.selector, BeforeSwapDeltaLibrary.ZERO_DELTA, LPFeeLibrary.OVERRIDE_FEE_FLAG);

+ return (BaseHook.beforeSwap.selector, BeforeSwapDeltaLibrary.ZERO_DELTA, 0);

}

```
