Lines 432 to 437 in 72e547e

	/** @dev Executes an unchallenged request if the challenge period has passed.
	* @param _itemID The ID of the item to execute.
	*/
	function executeRequest(bytes32 _itemID) external {
	Item storage item = items[_itemID];

I understand what's going on.

Submitted item.

Not challenged.

Can move to the list.

BUT

I think there is some automation script.

I would like to know more about it... How often does it run?
