The frontend plays node quizzes, but a node only completed once every one of its
8-13 lessons was completed separately, so students were stuck after the first
island of each unit. POST /api/nodes/{id}/quiz/complete now completes the node
(any score; score only sets stars/xp) and returns nextNodeId.
Also closes the other backend gaps found while auditing the frontend:
- /api/ai/ask without lessonId now picks the book from the user's grade instead
of skipping retrieval, so the "ask Pi" tab is grounded in the textbook.
- guest sessions return a refreshToken; they used to go silently 401 after 1h.
- lesson_complete throttle 10/hour -> 120/hour (a lesson here is 1-2 questions).
- progressPercent is per grade, not over all 2,617 lessons of every grade.
- a one-year plan (299,000 toman) is created by migration when no plan exists.

Three gaps found while seeding test data for the frontend, all of the same
kind: a contract that looks complete from the outside and is empty underneath.
Nothing in the codebase ever wrote a LeaderboardEntry. Not a signal, not a
service — only the admin form and seed_test_data. So /api/leaderboard returned
`entries: []` forever on any real server, and any row put there was a frozen
number that never tracked activity. rebuild_leaderboard now derives both
periods from real XP: all_time from UserStats.xp, weekly from a sum over
content.UserLessonCompletion in a window. It deliberately does not count
UserAnswer.xp_earned — that field is written but never added to UserStats, so
summing both would report roughly double. deploy.sh runs it every release;
a cron is the real answer once traffic is real, and the script says so.
'lesson_completed' was declared in Notification.TYPE_CHOICES but nothing
called notify() with it, so finishing a lesson produced no notification at
all. LessonCompleteView now emits one, on first completion only (the same
condition that grants xp/coins), inside the completion transaction so a lost
notification cannot leave a silent half-done state.
The notification list serializer returned only id/type/title/isRead. body and
created_at were on the model from the start but never exposed, so the frontend
had neither the text of a notification nor its time. Both added; the change is
purely additive, so the existing client keeps working.
472 tests green, up from 458. makemigrations --check, check and spectacular
are all clean.

Content
-------
Every node in grades 8, 9, 10, 11 and 12 now holds a full four-question
quiz — 121 more questions, filling the two حسابان دوازدهم nodes in
فصل ۵: کاربردهای مشتق that were empty and the two ریاضی هشتم nodes that
were short. The repo's own seed guard was already failing on those two
empty nodes; it passes now.
Grades 3, 6 and 7 are the other team's books and were left alone. 39 of
their 145 nodes still hold fewer than four questions, but none is empty,
so every node on the map still plays.
An audit over all 1,593 questions in grades 8–12 found no structural
fault: no question with the wrong number of options, no question with
zero or two correct answers, no empty or duplicated option, no leftover
LaTeX, and no two identical questions inside one lesson.
Contract
--------
Three endpoints were missing or malformed in the OpenAPI schema, which
matters more than it looks: that schema is the contract the frontend
generates its client from, so a view missing there is a view the other
repo cannot call.
- NotificationMarkReadView was dropped from the schema entirely, because
spectacular could not guess a request body for its PATCH and gives up
on the whole view rather than the one field. It declares request=None.
- PaymentRedirectView was dropped for the same reason; it answers with a
302 and no JSON body, which it now says.
- /api/health and /api/health/ collided on operationId and were emitted
as health_retrieve and health_retrieve_2. The slash variant exists only
for a monitor that calls it that way, so it is excluded from the schema.
`spectacular` now runs clean — no errors, no warnings.
Tidying
-------
Condensed the two longest comment blocks (18 and 14 lines) in
rag_verify_solutions and settings, keeping the measurement and the rule
and dropping the retelling. README gains the bulk question-authoring
workflow; the playbook's subagent section now points at the real tool
instead of describing the steps by hand.
458 tests pass.

progress/views.py
- GuestAwareReadThrottle (same guest-by-IP pattern as the other apps);
throttle_scope='read' on UserSummaryView, StreakCalendarView,
LeaderboardView.
notifications/views.py
- GuestAwareReadThrottle + throttle_scope='read' on NotificationListView.
- list capped at NOTIFICATIONS_MAX=100 newest (Meta.ordering already
newest-first); unreadCount still counted over the full set.
notifications/tests.py
- 150 rows -> 100 returned newest-first, unreadCount = 75.
rag/views.py
- ChunkListView: explicit order_by('-id') before the existing [:200] cap.
ai_tutor/views.py
- ConversationMessagesView: return the newest 200 messages in
chronological order instead of the whole conversation.
