There will be no courses. What was there: one draft called "jk" with two empty
lessons, and 4,000 lines of code around it — courses, modules, lessons,
enrolments, per-lesson progress, SCORM, BigBlueButton, completion certificates,
three React pages, a router, two models.
Its real cost was everywhere else. Every query that measured practice had to
remember `Quiz.course_id.is_(None)`, and forgetting it in one place would have
silently mixed course attempts into a learner's analytics; the bank predicate
carried a subquery to exclude a course's own questions from every search,
recommendation and share; quiz access had a second, parallel rule about
enrolment. All of that is gone, so the remaining rules say what they mean.
`quizzes.allow_review` goes with it. It was only ever enforced for a course
quiz, so it had become a promise nothing keeps — the public session page was
still offering "no answer review" about sessions that review fine.
The fixtures' question 5 lived in a course quiz and stood for "a question that
exists but is not in your bank". There is no such thing now — a question is in
the bank unless it is deleted — so the counts it kept out of the numbers are
back in, and the tests that turned on it now turn on deletion or on the
attempt that actually holds a question.
Files the LMS uploaded stay on disk and stay protected: LEGACY_LMS_PREFIXES in
app/utils/upload_access.py is what keeps them unreachable.

`Question.is_shared` defaulted to 1 and was only ever set by a route nothing
called, so in practice it divided the bank into "everything" and "everything,
plus your own private ones" — a distinction that cost every recommendation
denominator a join and never changed an answer. Who may reach the bank is the
site's own access rules; who may manage a question is the category grant tree.
So the two predicates the whole bank was built on are now the same thing, and
say what they actually mean: a question is out of reach if it has been deleted
or belongs to a course. Nothing else. The column is dropped, the route that set
it is gone, the bulk "share" action with it, and the Private tile and pill go
from the question manager.
The tests that turned on it have been rewritten rather than deleted, because
the rule they were really about survives: revoking a question still revokes
every session carrying it — by deleting it, which is the only revocation left.
Several others named a category holding exactly two reachable questions and
then answered two particular ids; that category holds four now, so they name
the pair instead. A session's own sharing flag is untouched — that is a
different thing, and it is still how a session is handed to somebody.

AI Mode could cite an article and link to it; it could not do the other
half of the job. POST /ai/conversations/{id}/practice turns an answer
into a study session, built from what that answer actually cited: a
question it named first, then questions filed under the category of an
article it named, then retrieval on the learner's own words. Everything
goes through the bank's visibility rules on the way out — a chat is not a
route to questions a learner could not otherwise reach. Study mode, never
exam: this is reading followed by practice, not a paper.
Two false alarms on the Settings page, both visible in a screenshot:
The STT test called /model/info on the LiteLLM proxy. Our virtual key is
scoped to llm_api_routes and cannot, so a working transcription model
reported a red 403. It now falls back to /v1/models, which the key may
call, and says plainly that the proxy would not confirm what the model is
for — presence, not suitability.
And the TTS test raised a 400 carrying an instruction ("use the Preview
button"), which the page rendered in red with a ✗. That is not a failure.
It answers, and Preview stays the way to hear a voice.
