Unfortunately, $sender_address is not set until after the "S" rewriting,
which happens as part of the address extraction from the command (as
does qualification).

Now that *is* weird, since it has matched the regular expression... No,
as you were. You've matched *another* regular expression as part of the
"if", which has destroyed the setting of $1 that you extracted from the
original.
I think you'll have to do this with two rewriting rules.
Rule 1: Use a regex to recognize unqualified addresses; rewrite to
"localpart@???".
Rule 2: Match on *@no.domain.supplied and use the regex you already
have, making use of $local_part. If your regex fails, rewrite back to
the unqualified address so that Exim will fail it.
