The catch-all path_regex "." policy challenged everything, including
Anubis's own API namespace /.within.website/x/cmd/anubis/*
(make-challenge, pass-challenge, static assets). In whole-request proxy
mode a JS-capable browser POSTs its challenge solution to
pass-challenge and received another challenge page (HTML) instead of the
verification verdict (JSON): the challenge app's fetch failed and the
browser rendered its own error — 'the request filters did not return an
alternative response'. Non-JS clients never POST the solution, so every
curl probe looked green while every human hit a wall.
Accept rule ordered above the catch-all; policy is volume-mounted ro from
this checkout, so the deploy updates it in place.
