Two buttons' worth of cost: wrong, or wrong and it should have been this.
The second is worth much more and is not required to give the first, so a
turn marked wrong with no target still lands as a usable negative.
The target is one of the seven intents, never free text: an unroutable label
would enter the one table V-632 fits prototypes from.
/api/correct is not behind the step-up gate. It reaches no router, no model
and no act path, and a correction that costs a passkey tap is one that does
not get made.
