I am so impressed that you have a detailed list that she signed off on. WELL DONE!
As for the mess, yep - it's her party and she can clean up the mess she made. Just keep being the awesome man and dad you are to your girls. They are so very lucky to have you.

"Someone I loved once gave me
A box full of darkness.
It took me years to understand,
That this too, was a gift."
