What a good question actually proves

When a learner answers a question correctly, it is tempting to record a tidy result: known. But the same correct answer can mean very different things.

If the answer came from a list of four options, it proves less than one recalled from nothing. If a hint was used, or a transcript was open, or the clip was replayed five times, it proves something different again. None of that is failure — support is how effortful success happens. It simply changes what the moment tells us.

So Passage keeps the context along with the outcome. Whether the task depended on the target directly or merely brushed past it. Whether the success came immediately after teaching, or a week later in a sentence the learner had never seen.

The practical result is that the system is slower to declare something learned and quicker to notice when knowledge is thinner than it looks. It also means the reason you are shown something can be explained in a sentence, which is the standard we hold ourselves to.
