CORRUPTION_DETECTED should be reserved for cases that are impossible,
short of physical corruption during execution or a major bug in the
code. We shouldn't use this for the kind of mistakes that can happen
during configuration or integration, such as calling a driver on a key
type that it doesn't support.
