The person who posted these calls them "reference genga" (参考原画). Although they're on layout sheets, I think they're detailed enough to warrant being considered something close to 1st KA, hence why I credited Miyazaki on the parent
The OP calls it "reference genga" again, so I presume that also means Miyazaki did first KA here
