Noted for the future. I actually wrote a draft myself and mostly used ai to translate it. And there were some "late discoveries" that required me to patch article fast. For instance, for older memory tier (without arenas) I was using 2MB+8B regions with 8B overlap - this allowed unaligned reads to happen without checks, but later I got 4MB non-overlapping regions with llvm read-write alignments to work and that allowed me to remove additional check on stores, make memory fully writable from host side and made atomics correct. So this kind of patch needed to land in article between my "finishing tinkerings".
