Fair enough.

Is there a way to prevent a Vault from minting counterfeit HashCash, or
do users have to trust the Vault?

Can you explain further on what you mean by this? Please correct me if
I'm wrong, but from my understanding, a user's HashCash is associated
with a single Vault. If so, wouldn't this mean that a Vault *could*
block a transfer out? Moreso if a Vault were to go offline.
