Disadvatage: must behave in a certain way, or receive a specific punishment

Does something like that exist? Such as: a Vestal must never engage in a sexual activity, or she loses her Clerical powers and gains Cursed.

Duty and Pact.

Some combination of those and/or Vow, anyway.

Code of Honor was the first thing that came to my mind.

Sense of Duty, Code of Honor or Vow would all work. And then you add the Pact (p.B113) limitation to all advantages. Getting cursed if you break the Vow is probably a 0-point feature.

Trading a self-imposed disad for something of a similar value but forcefully imposed (One Hand, Unlucky, Social Stigma) is fine. The normal situation is that you trade for a mental (non-self-imposed) disadvantage to indicate the psychological stress that made you break your standards, or you immediately owe the GM points, but it doesn't have to be a mental disadvantage.

Trading a self-imposed disad for one worth like, 8 times it's value (10 point vow -> cursed) is brutal if the trade is permanent. I would put a mitigator or terminal condition on the Cursed to bring it more in line with the original disad.

Secret turns into twice as much points in disads, and that's about as far as I'd be willing to go.

What if I had to inflict something like that via Affliction? A magic curse that imposes a 10-point Vow on the target, and if the target breaks the Vow, it gains a much bigger disadvantage (cursed?) or even dies. How would that work, and how much would it cost?

That sounds like the 150% version of the permanent enhancement. In this case its something you do before the curse sinks in, rather than to break it, but its a similar principle.

Disciplines of Faith, just to add to the list.

If there are bad external conditions that could be imposed on you, but that you can avoid by doing or not doing certain specific things, and if you do avoid doing those things in order to avoid the harmful consequences, that seems to me to be the exact specification of Duty. All the other things that have been proposed look like internal, self-imposed ethical constraints.
