Tutor (prompt tutor-v3-stepwise-plain): plain text instead of LaTeX/markdown,
with rag/services/mathtext.py converting whatever still slips through; full
step-by-step solutions with a check before the final answer; three tones by
grade; the last 6 messages of the conversation go to the model and follow-ups
are no longer served from another user's cache; book solutions the checker
disputes are kept out of the context; a questionId gives the tutor the
practice question and the student's wrong answer. /api/health reports when
the AI credit runs out. rag_model_benchmark compares chat models on verified
book problems (run on the server; credit ran out mid-run).
Map: only lessons that have questions count toward finishing an island,
lessonIds[0] / nextLessonId is always the next lesson to play, and a finished
island stays finished. The Seyar characters (sigma/delta/pi) are seeded.
Audit fixes, each reproduced before fixing:
- the plan is stored on the order, so paying a monthly order after starting
a yearly checkout no longer grants a year
- opening checkout no longer demotes an active subscription; renewals extend
from the current expiry; expired subscriptions are not reported active
- one discount code per order and only before the gateway; a 100% code
completes the purchase; lost Zarinpal confirmations are re-verified
- the unused /api/payment/webhook "mark paid" endpoint is removed
- XP counts only answers recorded on the server
- 6-digit OTP, each code dies after 5 wrong guesses; POST /api/auth/logout
- a guest who signs up keeps their account and progress (test phones excluded)
- affiliate commission on the first real payment; guests excluded
- parents with several children no longer get a 500
- SQLite runs transactions IMMEDIATE, since it ignores select_for_update
- admin login is rate-limited; display names drop phone numbers and links;
userQuestion is capped at 2000 characters
- server-side heart enforcement exists behind HEARTS_ENFORCED (off until the
frontend handles 403 no_hearts)
Not done on purpose: rotating the server's secret key and moving to Postgres.

خطاهای این پروژه خاموش‌اند: نامِ اشتباهِ collection یا فیلترِ نخورده نتیجه‌ی
خالی می‌دهد نه استثنا، و دستیار فقط بدتر جواب می‌دهد. این تست‌ها نگهبانِ
همان‌جاهایند.
TextbookLayoutTests بررسی می‌کند رشته‌ی هر فصل بینِ ingest و retrieval یکی
باشد و بازه‌ی صفحه‌ها پیوسته بماند. IngestBookResumeTests مطمئن می‌شود
صفحه‌ی بی‌مسئله دوبار پول نمی‌گیرد، صفحه‌ی خطادار در اجرای بعد دوباره
سراغش می‌روند، و upsertِ شکست‌خورده rollback می‌شود.
LessonContextResolutionTests نگهبانِ نرمال‌سازیِ «پایه نهم» → «ریاضی نهم»
است و اینکه مسیرِ gradeId و مسیرِ lessonId به یک collection برسند.
GradeAwarePromptTests جلوی برگشتنِ لحنِ دبستانی برای پایه‌های بالا را
می‌گیرد. FollowUpStaysGroundedTests پیامِ دومِ یک گفتگو را هم مستند نگه
می‌دارد.

next_refill_at was set on UserHearts but never read or recalculated,
so a heart lost to zero never came back. UserHearts.apply_regen() now
catches up missed 24h intervals on read/deduct, and lose_heart() starts
the timer only when it isn't already running.
Any user with an active (non-expired) subscription now skips heart
deduction entirely, regardless of which plan they're on — good enough
for now until per-plan perks are needed.

GET /api/home is the most-hit authenticated endpoint (every app open) and
was running one COUNT per node. Now it is a flat number of queries
regardless of grade size, and the shared curriculum skeleton is served
from cache; per-user progress/stats stay live.
content/views.py
- _node_status(): takes a precomputed set of completed lesson_ids and a
node's lesson_ids instead of firing its own COUNT query.
- HomeView.get(): one query for all completed lesson_ids of the user in
the grade, status computed in Python; grade tree (units -> nodes ->
lesson_ids, no per-user data) read from cache
(content:tree:grade:{id}:v{N}); missing grade -> 404 (was an
unhandled 500); grade with no units -> empty units, not 404.
- GradesListView: served from cache (content:grades:v{N}).
- curriculum_version() / bump_curriculum_version(): one shared version
key; bumping it invalidates every content cache key at once.
- both GET views get throttle_scope='read' + GuestAwareContentThrottle.
content/receivers.py
- post_save/post_delete on Grade/Unit/Node/Lesson -> bump_curriculum_version().
content/tests.py
- HomeViewScalabilityTests: query count flat for 2 vs 20 nodes; 2nd call
hits cache (no content_unit/node SQL); a new Node invalidates the tree;
missing grade 404; empty grade 200.
- GradesListCacheTests: list cached, invalidated on new Grade.
- ReadThrottleTests: /api/home returns 429 past the limit.

The math-app frontend prototype drives a RobotMascot with a fixed set of
moods; this gives that animation an explicit backend signal. Complements
the existing Lesson.mascot_animation / LessonIntro.mascotAnimation, which
are unchanged.
serializers.py
- AnswerResponseSerializer: new mascotMood field.
views.py
- QuestionAnswerView: mascotMood = 'happy' for a correct answer else
'encourage', on both the fresh response and the idempotent-replay
response.
tests.py
- QuestionAnswerMascotMoodTests: correct -> happy, wrong -> encourage,
and the mood is preserved across an idempotent replay.
