For early withdrawal Recipient and Arbiter has internal dependency

[kindkindk]

Hi,

I am finding this smart contract useful and would like to understand more about the published user flow.

In light of following two lines of code https://github.com/circlefin/refund-protocol/blob/master/src/RefundProtocol.sol#L272
function earlyWithdrawByArbiter() external onlyArbiter

and https://github.com/circlefin/refund-protocol/blob/master/src/RefundProtocol.sol#L279C1-L280C1
if (ecrecover(withdrawalInfoHash, v, r, s) != recipient) {

The flow for earlyWithdrawByArbiter() seems to be :

• Recipient creates payload and signs as shown in tests https://github.com/circlefin/refund-protocol/blob/master/test/RefundProtocol.t.sol#L685
• Recipient sends the payload to Arbiter
• Arbiter submits the transaction

I mean to highlight dependency between Recipient and Arbiter for Early Withdrawal scenario. Is this understanding correct ?
