Means
an app guard's finding breaks the error contract

a finding whose code is not X_-prefixed SCREAMING_SNAKE, an empty cause, or a fix that says "check" or "make sure" and names no command. Held to the identical rule x verify's errors step applies to shipped source — and checked on the returned value, which is the half a static scan cannot reach, since a fix built at run time has no literal
Fix
x verify --json — then give the finding an X_ code, a cause, and a fix naming a command
