Version 0.71.0

The two doors your account code opens now run the same check — one piece of code, not two copies of it.

Your account code opens two doors: signing in, and erasing the account without signing in. Both have to do the same work before they believe you — the human check, both lockout counters, and spending the same computing time when no such account exists so that a stranger cannot learn which codes are real by timing us — and those thirty-five lines were written out twice, character for character. That is a real risk and not a tidiness complaint: if we ever tightened the lockout on one door and forgot the other, the forgotten one becomes the cheaper door for somebody guessing account codes. There is now one piece of code both doors call, what stays different is only what is genuinely different, and nothing about the answers either door gives has changed.
