 In the execution loop, the `handleOps` call must perform the following steps for each `UserOperation`:
 
 * **Call the account with the `UserOperation`'s calldata**. It's up to the account to choose how to parse the calldata; an expected workflow is for the account to have an `execute` function that parses the remaining calldata as a series of one or more calls that the account should make.
-* If the calldata starts with the methodsig `IAccountExecute.executeUserOp`, then the EntryPoint must build a calldata by encoding `executeUserOp(userOp,userOpHash)` and call the account using that calldata.

 * After the call, refund the account's deposit with the excess gas cost that was pre-charged.\
  A penalty of `10%` (`UNUSED_GAS_PENALTY_PERCENT`) is applied on the amount of gas that is refunded.\
  This penalty is necessary to prevent the UserOps from reserving large parts of the gas space in the bundle but leaving it unused and preventing the bundler from including other UserOperations.
