http-429.sh returns 429 to the first request for an endpoint and
forwards later ones to git-http-backend so the retry succeeds. It
remembers that it has already answered 429 by checking for a shared
state file with "test -f" and creating it with "touch".

There is no regression test. The check and the set are adjacent commands
with nothing in between to synchronize on, so the overlap cannot be
forced deterministically, only reproduced by chance; the fix is
preventive.

A lot of AI-fluff in this message that could have otherwise been much
briefer, but okay.

You are right. I will go through all the prose in the series and re-write it
by hand. I apologize for giving you unnecessary AI-fluff to read and will
not do it again.
