1. The hole becomes clean enough that you can chase it with a tap.

HMMM, novel idea in concrete...

Please send more info on tapping concrete. *I'm sixty, and this is the first
I've heard about it.

Please let us know when was the last time you screwed something into concrete?

other than Tapcons or Simpson Titen bolts (supposedly removed &
reinsertable!?)

In sound concrete this could work in OP's app but I would use them.

I would use a small rotary hammer bit to surgically drill away some of
the concrete & remove the lags.
Then I'd embed SS threaded studs in epoxy Sika AnchorFix #1 (5 min) or
#3 (1 hr)

Other post about using core drill is a good idea......

I removed three 5/8" x 10" embedded hex bolts by coring around them
with a Hilti DCM 2.0 with a 2" x 18" core bit.
Then I used setting compound (PourStone) to embed post anchors.
