SPOOL3-4 - IMPLEMENT BEFOREDEPOSITCHECK

• Commit: https://github.com/SpoolFi/spool-v2-core/commit/8fc336ce65c044d62c56069ba0ee83ccc7d2a092

• Description: Acknowledged, implemented in commit hash above.

SPOOL3-2 - REDUNDANT SAFEAPPROVE USAGE

• Commit: N/A
• Description:
  • This optimization is acknowledged; However, on review of this issue, we have decided to not implement a change. The optimization is a non-security related change to code implemented by all strategies, including ones already deployed (the change is for Strategy.sol). As a result, we would have to maintain two versions of Strategy.sol in the codebase (existing one for already deployed strategies, and a newer one with these changes). We would rather not maintain two versions of Strategy.sol in the codebase at this point, unless there is a security related concern.

SPOOL2-2 - DISCREPANCIES IN _REDEEMFROMPROTOCOL FUNCTION IMPLEMENTATION

• Commit: https://github.com/SpoolFi/spool-v2-core/commit/86065428a4d5e6de3c7b10909db532033c578c80

• Description:

  • Acknowledged, implemented in the commit hash above.

  • the _redeemFromProtocol() function now uses just one slippage value, for the output WETH amount. We pass an empty array to redeem inner for the slippages, as we assume that we will catch any issues on the output WETH amount. We must allow passing slippages to _redeemInner, as in the emergencyWithdraw function, we will just get back stETH and frxETH and send to the emergency recipient, and so we still want to use slippages for stETH and frxETH in this case. I've updated the redeemFast/emergencyWithdraw description, to better relate this.

  • In this commit, I have also included some event emissions that we missed:

• in assetGroupWrap, we return a ratio array, which represents the amounts of stETH/frxETH that's used as input t
