Leveling completion is finally in sight!

I have my 4” blocks sunk and leveled within +-1/8“. I need to level a bit where the bottom rail will be, but that should be easy with all the dirt I now have to add and tamp down.

My question is, since I had a lot of rocks/pebbles in my soil it was impossible to just dig out a tidy rectangle for my blocks. I now need to backfill around the blocks. I used 1”+ of stone dust under the blocks, should I backfill with stone dust or just dirt or both?

Thanks!
