I indeed reuse many concepts there, but a few years before I had also
implemented the original paper and the correctness proof in Agda:
It was one of my first Agda programs and I've never put much effort into
cleaning it up so the correctness proof is quite rough, though it should be
readable with the paper on the side.
One complication is that it threads various extensionality proofs alongside
"Property"'s so that we don't need to postulate functional extensionality.
