Did your helper return message=... and status=... annotations to Squid?
The %note logformat code expands into transaction annotations.
Annotations come from helpers (and other sources irrelevant for this
discussion).

You seem to be asking a question that only you can answer: You know what
your helper can do and how it is used. url_rewrite_extras is about
information passed from Squid to your helper. You know what information
the default url_rewrite_extras passes to your helper. Is that
information enough for your helper to responds with annotations
containing "the ACL that was matched and the result" info?
