Selection Edge Pixels

Attached is a simplified illustration of a problem I've had with Photoshop since the last millenium. Lines appear around selections from out of nowhere. The illustration shows to identical gray layers. Below it I placed a circular marquee on top of the layers. On one layer I deleted the contents of the marquee circle and on the other I deleted the inverse. I did not touch the circle. In the lower panel, on the right you can see the edited layers as I described them. You can also see a circle on top of the two layers in the main panel. The circle is formed from destroyed pixels. I didn't assign a width to the stroke of the circle, so the two shapes should fit perfectly together with no gap. I placed a black layer underneath, and you can see the black through the gap.
This might seem like a "so what?" problem, but it's not. Cutouts always end up with unwanted lines around them. Here's a real world example. I've been trying to remove a shadow from a face caused by a baseball cap. I've tried a bunch of different techniques to lighten the shaded portion, but Photoshop keeps highlighting the edge.
I'll be posting a series of "Where the hell did that come from?" questions as they arise. I'm running out of cuss words, and I do want to go to Heaven eventually. Hopefully, one or more of you can save my soul.
