It's the only thing I knew of that had changed.

Thanks, that was exactly the problem, and now in retrospect it's
clear why these commands didn't find it:

  /etc[0]#git log --patch -- /etc/hosts
  /etc[0]#git log --patch -G"$(dnsdomainname)"

whereas this one would have:

  /etc[0]#git log --patch -G"192\.168"

I changed the third octet in the chroot's '/etc/resolve.conf' to
match the host system's, and everything seems perfect now.

Firefox is supposed to use DNS over HTTPS automatically in the US,
with cloudflare as default. But I tried enabling DNS over HTTPS
just now, and firefox offered no choice except "custom". Perhaps
debian 'stable' (firefox-91.12.0esr) just hasn't caught up yet.

It takes little time, and diffing '/etc' would have found the answer.
But I found that 'bookworm' now has gcc-12 for x86_64-pc-linux-gnu:

/opt/lmi/src/lmi/compiler_gcc_version.make:67: Untested cpp version '12'
/opt/lmi/src/lmi/compiler_gcc_version.make:75: Untested g++ version '12'

so now I have lots of fresh puzzles to keep me occupied.
