Asked for: no tutor on a question outside a session. The tutor is handed the
correct answer and told it may explain it, so it is answer-side content — and
once that rule is written down, the same rule catches two bigger holes:
- `GET /questions/bank` returned `correct_answer`, `explanation`,
`option_explanations`, `key_points` and `attending_tip` for every question in
the bank, to any signed-in learner. It is the question manager's listing, but
nothing stopped anyone calling it: the whole answer key, one request away
from the questions it answers. Stems are still listed to everyone; the answer
side now goes only to whoever writes that question.
- The explanation image behind a question was readable by the same rule, with
no attempt behind it.
"Whoever writes it" is one function now — `may_edit_question` — and it means
moderation, authorship, or an editorial grant that reaches where the question
is filed. Everyone else earns the answer by sitting the question, which is what
an attempt is. The bank browse, the search, the session and the review are all
unchanged; the frontend already sends `attempt_id` everywhere it shows an
answer.
The question manager was reachable by a learner with no grant, and would now
load as a bank of stems with every answer field blanked — a broken page rather
than a door that is not theirs. It says so instead.
Also, while looking at where cards surface: the answer review showed neither
the topic reading nor the cards written against a question, though the player
has shown both under the answer for a while — and the review is the one place
a learner goes through everything they got wrong. The list form of that
component fetched its cards and then dropped them on the floor.
