During the jar test did you take pictures at 1 minute and 1 hour also? Those would have helped you determine whether you have a lot of silt or a lot of sand. In any case there's not much to do with that information. You're in the range of pretty good soil. If you still have the jar of soil you can shake it up again and take the 1-min and 1-hour pix.

Where do you live? It's important to know.

Are you going to grade the front before installing what appears to be a walkway from the driveway to the front door? You should or else the grading will break your new walk way even if it's concrete. Here is what grading looks like, by the way.

The guy on the blue Ford is grading with a box blade. The Skid Steer in back likely is collecting rocks. Skid Steers and Bobcats are horrible for leveling. With their short wheelbase and top heavy nature, they can take a week to do what a tractor and box blade can do in a few hours.

A lot (LOT) of people think they have clay soil when what they have is excess magnesium salts in the soil. Magnesium absorbs humidity from the air and can make even sandy soil into a gooey mess when it's wet. A good soil chemistry test will tell you about your soil salts (sodium, calcium, magnesium, and potassium).

What are the dead spots (2nd picture)?

What kind of grass do you have? What do you eventually want?

Looks like peanut butter.

I think you have a silty clay soil. It's a good soil to have. It holds moisture and nutrients well. But, it can compact fairly easily. I'm guessing you live in the southeast or mid-atlantic.
