The deity is infallible. That is its stated nature within the bible.<quoted text>
Where does it say it was a planned perfection?
Personally, it makes little difference to me since I find it to be a myth, but the deity is said to be perfect in all it does.
Look at this verse in Deuteronomy.
TNK Deuteronomy 32:4 The Rock!-- His deeds are perfect, Yea, all His ways are just; A faithful God, never false, True and upright is He.(Deu 32:4 TNK)
Now: TNK Genesis 2:2 On the seventh day God finished the work that He had been doing, and He ceased on the seventh day from all the work that He had done.(Gen 2:2 TNK)
The claims within the bible are that all work the deity performs is perfect.
The deity judged the work it had performed as "very good":
TNK Genesis 1:31 And God saw all that He had made, and found it very good. And there was evening and there was morning, the sixth day.(Gen 1:31 TNK)
I'm not the one writing this stuff. That is the "official" Judaic take on the deity. Within the myth, all the deity does is perfect. This is no secret.
