Description
in the following example an image created with background-image has an even width (4 pixels) .
It is placed in the middle (50%) of the div element containing it. This element has an odd size (9pixels).
result: the image has 3 pixels to its left and 2 to its right.
it could have been 2 pixels to its left and 3 to its right.
My question is not why. My question is where are the documents that specify this type of CSS decision?

Locate the normative text that explains how the midpoint is resolved for an even-sized image in an odd-sized container, then document or link that decision so the issue has a clear reference.
