- /api/ai/ask: at most AI_MAX_CONCURRENT_PER_WORKER (12 of 32 threads) answers per worker;
beyond that 503 assistant_busy + Retry-After before any quota is reserved. Without it a
burst of questions (3-40 s each) took every thread and the map and quizzes queued behind.
The slot is held until the stream is actually finished or closed.
- Answer submission 21 -> 14 queries, 15.4 -> 11.0 ms: one query for all choices, locked
get_or_create for node progress and streak, and today's streak recorded once per day
via the cache instead of a transaction per answer.
- /api/home 12.4 -> 8.6 ms: the user's completions are read by user_id instead of an IN list
of ~600 lesson ids; the dict is returned directly (serializer stays the Swagger contract,
HomeMatchesItsSerializerTests keeps them equal).
- otp_login per-IP 30 -> 300/hour: a class of 30 on one school Wi-Fi filled it; guessing is
bounded per code and per phone.
- /api/health aiConcurrency.

- content: unit_is_free/has_unit_access; questions, node quiz, answer and lesson/node
complete return 402 subscription_required outside the first unit without an active
subscription. /api/home units carry requiresSubscription.
- subscription.0013: monthly 498k, quarterly 798k, six-month 1,298k toman, unlimited
hearts, 3 AI questions/day; packs stay on sale for more questions.
- AI_DAILY_QUOTA_FREE default 3 -> 2.
- /api/subscription/status adds planTitle, planDurationDays, aiDailyQuota.
- tests: content/tests_paywall.py; existing unlock-order tests get a subscription.

- content: POST nodes/{id}/quiz/complete and lessons/{id}/complete refuse a locked island
(403 node_locked, same rule as /api/home) and a user who has not answered every question
(409 answers_missing). Before, only a user with zero hearts and no answers was refused, so
anyone else finished any island, locked or not, and finishing a locked island's lessons
unlocked it. A node or lesson with no questions still passes when unlocked, with no XP.
The client can no longer understate totalQuestions to buy stars.
- throttle_scope on 15 routes that had none (question bank without login, intro, hearts,
notifications, tickets, plans, subscription status, orders, offers, affiliate, assistant
history and feedback, logout).
- admin: OTPCode and Session can only be added/changed by a superuser.
- deploy.sh: integrity-checked DB backup before migrate (keeps the last 2); no migrate without it.
- docs and CLAUDE.md updated to say what is verified and what is not.

accounts.0008 drops the columns and refuses to run while guest rows exist.
Docs describe the current state; tests that only proved guest behaviour are gone.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
- accounts admin: phone/is_guest read-only for non-superusers, device_id filter lookups refused,
auth.User/Group admin writable only by superusers
- campaigns: delivery log needs view permission
- phone/OTP/birth date: any Unicode digit normalised or rejected with 400; unknown gradeId is 400
- shared demo guest is never turned into a person's account by logging in
- /api/home with unknown gradeId is no longer cached (LocMemCache flood reset throttle counters)
- /api/progress/nodes: one query, huge unit is 400
- BazaarCredential token filter lookups refused
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
- Admin: refund/cancel/mark-resolved/Bazaar-link actions need change permission; question and
curriculum import need add/delete; content browser needs view_question; guest device ids are
shown to superusers only.
- Accounts: registering a guest's phone revokes the guest's earlier sessions; self-deletion keeps
Redemption, UserOffer and the phone's OTP rows; the public demo guest cannot be deleted
(DEMO_GUEST_DEVICE_IDS); display-name contact filter covers any separator and social handles.
- Payment: callback without Authority is 400; a second Bazaar purchase on a paid order is 409;
orders snapshot credits/hearts/days at creation (payment.0011).
- Assistant: a broken diagram no longer makes a streamed answer free; a late off-topic marker
refuses the answer (not stored, not cached); a disconnect saves the partial answer; only
KNOWN_COLLECTIONS are searched.
- Infra: secret-key file is created atomically (workers no longer split keys); no default
INTERNAL_SERVICE_KEY; Kavenegar key and Bazaar token kept out of error logs; Swagger/ReDoc
pinned; schema throttled; docker compose bound to 127.0.0.1; non-ASCII digit ids are 400;
ticket text capped at 5000.
- docs/security-before-production.md: remaining open items 24-31 and the guard tests.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- seed_content no longer undoes admin work: a SeedRecord ledger (content/seed_sync.py)
stops deleted/renamed/re-worded content from being recreated and keeps admin-edited
lesson text; new rows in the seed files still arrive (migration content.0010)
- plan list cache is invalidated on Plan save (receiver used a stale 'v1' key)
- token refresh per-IP cap 30/hour -> 600/hour (TOKEN_REFRESH_IP_RATE)
- a failed gateway result only changes a pending order (forged NOK no longer
overwrites refunded/canceled)
- tutor gets the correct answer only after the student has answered
- support reply notification moved to a TicketMessage post_save signal
- global daily cap on paid AI questions (AI_GLOBAL_DAILY_MAX, default 3000)
- Bazaar verify uses only the order's SKU; bazaar orders require a SKU
- /api/health warns on the committed signing key; deploy.sh saves local commits;
400 for bad ?unit= / ?period=; account delete keeps the referrer's Conversion
- earlier today: no stub answers outside DEBUG, ?grade= removed, logged fallbacks
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- /api/ai/ask: the stub answer is reachable only under DEBUG or
RAG_FORCE_MOCK. Without RAG keys on the server it used to return 200 with
"this is a stub, set OPENAI_API_KEY" and spend the student's quota; now 503.
- /api/home: the `grade` alias is gone and sending it is a 400 instead of a
silent fallback to the user's own grade. No client sent it.
- activate_subscription logs ERROR when the paid order's plan no longer exists
(it silently became 30 days).
- resolve_grade_title logs instead of `except: pass`; curriculum_io no longer
reads an `intro_text` key no file contains.
- CLAUDE.md: "No silent fallbacks" rules for future agents.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- The zero-hearts check moved inside the answer transaction: two wrong
answers sent at once with one heart left were both accepted (reproduced
with two threads).
- Finishing a lesson or an island without hearts and without having
answered its questions is now 403 no_hearts; before, quiz/complete let
a student move on island after island with zero hearts. Losing the last
heart on the last question still finishes the island.
- A heart that came back while waiting is now saved before answering, so
the reply no longer says 0 hearts left (the app then showed the
no-hearts page to someone who had a heart).
- The 403 also carries fullRefillAt for the waiting screen.

- remove the family app from the root (separate parent accounts, invite codes, parental
settings); progress.0006 drops its tables, permissions and migration history, and
Profile.parent_phone, the two family notification types and ?userId= on
/api/progress/nodes go with it
- GET /api/user/weekly-report: last 7 days next to the 7 before (estimated minutes,
questions, accuracy, islands, tutor questions) for the "parent report" page
- profile birthDate in Jalali (accounts/jalali.py), ages 5-99, birthYear derived from it
- GET /api/payment/invoices; orders now snapshot list price and plan title
- tutor answers only math: server pre-filter, scope rule in the prompt (tutor-v11),
refusal marker replaced with fixed text; self-harm gets a help line instead
- streamed answers now record token usage (it was always 0)
- daily tutor quota: AI_DAILY_QUOTA_FREE (default 3) vs Plan.ai_daily_quota
- delete_users management command for wiping test accounts across every app
- docs/ai-cost-and-guardrails.md: measured cost per question and guardrail results

GET /api/support/tickets returns the caller's last 20 tickets with their
support-reply count, on the read throttle so listing never spends the
30/hour create quota. Before it the app kept ticket ids only in one
browser's localStorage, so a ticket and its answer vanished with the device.
Completion notifications now use Persian digits and drop the
'with 0 stars ... 0 points' sentence when nothing was earned.
.env.example: NUM_PROXIES=2 (ArvanCloud + nginx), KAVENEGAR_OTP_TEMPLATE,
BAZAAR_PISHKHAN_API_SECRET, sandbox off by default; removed variables the
code no longer reads.

Kavenegar is being switched on, so every OTP request now costs credit:
- phone numbers are normalised to 09XXXXXXXXX everywhere (login, OTP,
family invite, TEST_LOGIN_PHONES keys) and existing rows are migrated;
non-Iranian and landline numbers are rejected before any SMS
- cooldown and a daily per-phone cap are counted in the database, so the
three gunicorn workers no longer triple them
- a global daily OTP SMS cap (default 300) stops SMS pumping
- per-IP rates widened for CGNAT / school Wi-Fi (env-overridable)
- provider message id is logged; SMS text warns not to share the code
Second audit round: an offer no longer shortens a longer paid plan,
Zarinpal error bodies no longer 500, island XP reaches the parent report,
a non-numeric questionId no longer 500s after the answer is generated.
596 tests green.

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.

Each heart used to take 24 hours, so a student who lost all five waited up to
five days. Now one heart returns every 5 hours, and 24 hours after the first
heart was lost they all come back at once (the owner's call). /api/user/hearts
reports both times (nextRefillAt, fullRefillAt); an existing timer longer than
5 hours is shortened the first time it is read.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Found in a deeper pass over what the frontend's flow actually touches:
- Nothing in the app ever wrote StreakRecord: "days in a row" was 0 forever
for every real user. Answers and lesson/island completions now record the
day (Tehran time); a broken chain shows 0. A streak error never fails the
answer itself.
- /api/leaderboard only changed when someone ran rebuild_leaderboard by
hand. It is now computed live (60s cache); weekly counts island XP too.
- gunicorn ran 3 sync workers with a 30s timeout, so every "ask Pi" stream
pinned a whole worker (~10s, GapGPT buffers the answer) and three at once
queued the entire API. gunicorn.conf.py (read automatically from the
working directory) switches to gthread, 8 threads, 120s timeout.
- Every /api/ response now says Cache-Control: private, no-store, so turning
on caching in the ArvanCloud panel can never serve one student another's data.
- /api/user/summary named no active plan ever ("subscription app not
implemented yet" had long stopped being true).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.

Grade ids were the order the books were imported in (ninth=1, eighth=5), so
gradeId: 5 meant eighth grade and the admin, the question filter and the API
all listed grades out of order. Grade.number (1-12) is now read from the title,
new grades take it as their id, and migration 0008 moves existing ids plus every
reference to them: Unit, the loose grade_id in accounts/ai_tutor/rag, and the
grade target inside campaign JSON. Unnumbered demo grades move above 100 and the
id sequence is raised past 12 so they never collide with a real grade.
The frontend needs no change: it always reads gradeId from the server.

The Swagger header was a list of features. That is what the project does, not
what a caller needs. It now opens with the three things anyone integrating
against this API asks first: how do I get a token, what does an error look like,
and when do I get rate limited -- plus the field-naming and date conventions,
and a note that the schema is the contract and clients should be generated from
it rather than written from memory. Swagger UI and Redoc both render Markdown,
so it is structured rather than one long paragraph, which also fixes how badly
the old mixed Persian/Latin line wrapped right-to-left.
Two defects surfaced while checking the rendered schema:
- /api/health was absent from the schema entirely. The trailing-slash alias was
excluded with extend_schema(exclude=True)(HealthView), but that decorator
mutates the class, and both routes pointed at the same class, so the canonical
route disappeared with it. A subclass now carries the exclusion, and the
endpoint is back, exactly once. Endpoint count is 56, not 55.
- One endpoint was tagged 'محتوا (content)' while every other content endpoint
used 'Curriculum (content)', which split the group into two sections.
Tags are now declared with descriptions and ordered by the path a real user
takes, rather than alphabetically.
Comment pass over the codebase, keeping the substance and dropping the noise:
the "⚠️ اضافه شده" prefixes dated comments against a moment no current reader
shares; "فاز ۲ / بخش ۴" referenced a plan that no longer exists and only
repeated the app name on the next line; "فاز اول - ۴ از ۱۱ اپ" had drifted (there
are fourteen). INSTALLED_APPS is now grouped by responsibility. The
TEST_LOGIN_PHONES block in settings shrank from 29 lines to 8 now that the same
explanation lives in docs/operations.md and .env.example -- a comment beside the
code should carry what a code reader needs, not a copy of the runbook.
Checked mechanically that no comment references an identifier that no longer
exists: zero. The dated measurements in rag/services/ingest.py and
generate_questions_from_chunks.py were deliberately left alone -- a measurement
carrying the date it was taken is the useful kind.

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.

سه کارِ بههمپیوسته که از یک کشف شروع شدند: راهحلهایی که vision از کتاب
درآورده گاهی غلطاند، و این خطا در بازیابی دیده نمیشود — فقط وقتی کسی به
`solution` اعتماد کند خودش را نشان میدهد.
۱) بازبینیِ راهحلها (rag_verify_solutions)
هر chunk دوباره حل میشود و با کتاب مقایسه. نتیجه سهحالته است، نه بله/خیر:
اجرای اول با بولی ۱۹٪ خطا گزارش کرد؛ خواندنِ دستیِ نمونهها نشان داد ۳۵٪ از
آنها مسئلههایی بودند که به شکلِ کتاب ارجاع میدادند و اصلاً قابلِ قضاوت
نبودند، و ۲۴٪ موردی که «۳/۱۰۴» را کسرِ ۳÷۱۰۴ خوانده بود نه عددِ ۳٫۱۰۴. با دو
حالت، «نمیدانم» ناچار به «غلط است» ترجمه میشد.
با سه حالت و پرامپتی که این دو تله را میشناسد: ۲٬۱۱۹ chunk بررسی شد،
۱٬۱۱۲ درست، ۱۲۳ غلط (۵٫۸٪)، ۸۸۱ غیرقابلِ قضاوت. آن ۸۸۱ رایگان برچسب خوردند
چون پیشفیلتر قبل از هر فراخوانی کنارشان گذاشت.
`solution` هرگز بازنویسی نمیشود — کتاب باید کتاب بماند. برچسب در payloadِ
Qdrant هم مینشیند، ولی با نامی که `retrieval._payload_text` نمیخواند: یک
نویسه هم به متنی که به مدل میرسد اضافه نشد.
نمونهی خطاهای واقعیِ کتاب که پیدا شد:
BMI = ۱۰۰/(۲٫۷۴)² کتاب: ۳۳٫۲ درست: ۱۳٫۳
۱۶ آبی + ۲۴ صورتی کتاب: «کل ۵۰» درست: ۴۰
بزرگترین عددِ ۴رقمیِ بیتکرار کتاب: ۸۵۳۲ درست: ۹۸۷۶
g(x) = x³ − ۲ کتاب: «نمایی» درست: چندجملهای
۲) سوالها فقط از راهحلهای تأییدشده
۱٬۱۹۹ سوال در content/seed/questions.json، همه از chunkهایی که برچسبِ
«درست» گرفتهاند. هر شش پایه برنامهی درسی دارند (۱٬۹۲۸ درس) — هشتم و دهم
تازه ساخته شدند.
۳) GET /api/nodes/{id}/quiz
واحدِ بازی در اپ «مبحث» است ولی سوالها به «درس» بستهاند، و درس اینجا
ریزترین دانه است: یک نوعِ مسئله، نه یک جلسه. نتیجهاش این بود که اپ برای یک
آزمونِ چهارسوالی باید دهها درخواست میزد. این اندپوینت از همهی درسهای مبحث
نمونه برمیدارد، حداکثر یکی از هر درس تا آزمون روی یک مهارت گیر نکند.
درهمریزی با بذرِ nodeId:userId پایدار است: رفرشِ صفحه همان آزمون را میدهد،
نه مجموعهی تازهای که پیشرفت را بیمعنا کند. `questionCount` جدا از
`requested` میآید تا مبحثِ کمسوال وانمود نکند کامل است.
──────────
اصلاحاتِ جانبی که سرِ راه لازم شدند:
• QDRANT_TIMEOUT_SECONDS: کلاینت بدونِ timeout ساخته میشد و پیشفرضِ ۵
ثانیهایِ کتابخانه ingestِ کتابِ هشتم را روی اولین فراخوانی کشت.
• پاکسازیِ نقاطِ نیمهنوشته: upsert با wait=True ممکن است نوشته باشد و فقط
جوابش تایماوت شده باشد؛ مسیرِ جبران فقط ردیفهای DB را پس میگرفت و هر
retry یک نسخهی تکراری در Qdrant جا میگذاشت (۸ مورد در پایه نهم، پاک شد).
• تشخیصِ سقفِ حساب: «insufficient user quota» با فاصله میآید نه زیرخط، و
محافظِ اول نمیگرفتش — یک اجرا ۷۷۰ فراخوانیِ محکومبهشکست زد.
• پرامپتِ vision حالا میخواهد محتوای شکل داخلِ متنِ مسئله نوشته شود. ۴۲٪ از
محتوای موجود به شکلی ارجاع میدهد که در متن نیست؛ مدل آن را دیده بود ولی
از او خواسته نشده بود بنویسدش. کتابهای موجود قبل از این قاعده وارد شدهاند.

رنگ و آیکونِ مبحث تازه اضافه شده بودند و هنوز هیچکس پرشان نکرده، یعنی
کارتها تا وقتی کسی از پنلِ ادمین وقت بگذارد بیرنگ میماندند.
حالا وقتی فیلد خالی است، مقدارِ پیشفرض از پالت و آیکونهای خودِ اپ میآید
(همان رنگهای طرح و همان آیکونهایی که از lucide وارد میشوند)، تا بومی به
نظر برسد نه وصله.
چرخشی بر اساسِ جایگاهِ مبحث در پایه است، نه تصادفی: رنگی که بینِ دو بارگذاری
عوض شود بدتر از بیرنگ بودن است، و دو مبحثِ کنارِ هم نباید یکرنگ دربیایند.
مقدارِ صریحِ ادمین همیشه برنده است.

صفحههای فرانت خوانده شدند و با API مقایسه شدند. ساختارِ ما از کتابِ واقعی
درآمده و درستتر است، پس مدل عوض نشد — ولی چند چیز کم داشت.
مهمترینش یک باگ بود: /api/home پارامتر را `grade` میخواند و کلاینتی که به
فرانت فرستادیم `gradeId` میفرستد. پارامترِ ناشناخته بیصدا نادیده گرفته
میشد، یعنی کاربر پایهای را انتخاب میکرد و نقشهی پایهی دیگری میدید
بدونِ هیچ خطایی. حالا هر دو نام پذیرفته میشوند (`gradeId` نامِ درست است،
با بقیهی API یکی). تستِ سرتاسریِ قبلی این را نگرفته بود چون home را بدونِ
آرگومان صدا زده بود.
/api/grades حالا lessonCount میدهد. فهرستِ پایههای فرانت تا دوازدهم است
ولی محتوای ما تا نهم؛ بدونِ این عدد، کاربر پایهی خالی را انتخاب میکند و
صفحهی خالی میبیند بیآنکه بفهمد چرا.
GET /api/nodes/{id}/lessons اضافه شد. /api/home فقط شناسهی درسها را
میدهد، ولی نقشهی مهارت برای هر قدم عنوان، نوع، زیرنویس و «انجام شد» لازم
دارد — بدونش فرانت باید برای هر درس یک intro جدا میگرفت.
Lesson حالا kind (آزمون/ویدیو) و متنِ سهتکه دارد: توضیح، مثال، حلِ
گامبهگام. ویدیو از قبل سوالِ بازِ محصول بود و فرانت آیتمش را دارد؛ حالا
API میتواند بیانش کند، حتی اگر محتوایش بعداً بیاید. Unit یک blurb گرفت و
Node آیکون و رنگ، تا فرانت رنگها را هاردکد نکند. هیچکدام اجباری نیست، پس
محتوای موجود دستنخورده کار میکند.
PATCH /api/user/profile حالا age را هم میپذیرد (صفحهی ثبتنامِ فرانت سن
میپرسد). ذخیرهسازی همچنان birthYear است چون کهنه نمیشود؛ این فقط ورودی
را ترجمه میکند تا دو طرف حسابِ متفاوت درنیاورند.

پیدا کردنِ «سوالهای فلان مبحث» در فهرستِ پیشفرضِ جنگو عملاً ممکن نبود: باید
بینِ چند صفحهی جدا با دراپداونهای هزارتایی بالا و پایین میرفتی.
/admin/content/question/browse/ چهار ستونِ آبشاری دارد — پایه → فصل → درس →
مبحث — و هر ستون فقط وقتی پر میشود که قبلی انتخاب شده باشد، پس هیچوقت
فهرستِ هزارتایی جلوی چشم نیست. تهاش سوالهای همان مبحث با گزینههایشان
میآیند و از همانجا ویرایش یا اضافه میشوند.
کنارِ هر سوال دو عددِ تصمیمساز: گزارشهای بازِ کاربران، و درصدِ پاسخِ غلط.
درصد زیرِ ۵ پاسخ نشان داده نمیشود — یک نمونهی کوچک سوالِ سالم را
«مشکلدار» جلوه میدهد. همین دو ستون به فهرستِ سوالها هم اضافه شدند.
content.QuestionReport و POST /api/questions/{id}/report تازهاند: تنها
بازخوردی که تا امروز جمع میشد مالِ چتِ دستیار بود، و روی سوالهای مسیرِ
آموزشی هیچ راهی نبود که کاربر بگوید گزینهی درست غلط است. گزارشِ بازِ تکراریِ
همان کاربر ردیفِ تازه نمیسازد تا دابلکلیک آمار را بههم نزند.
وابستگیِ تازهای اضافه نشد: چند اندپوینتِ کوچکِ JSON و JavaScript ساده.

سینیور خواست زودتر به فرانتاند وصل شویم تا از آنجا هم تست شود. اینها
سمتِ ما لازم بودند:
CORS با allowlist صریح (نه ALLOW_ALL): احرازِ هویتِ ما توکنِ Bearer در هدر
است، پس origin ناشناس نباید از مرورگرِ کاربر به API ما بزند.
CORS_ALLOW_CREDENTIALS عمداً خاموش میماند — کوکیای در کار نیست و روشن
کردنش فقط سطحِ حمله اضافه میکند. CorsMiddleware بالاتر از CommonMiddleware
گذاشته شد وگرنه ریدایرکتِ APPEND_SLASH و خطای ۴۰۰ هدرِ CORS نمیگیرند و در
مرورگر بهشکلِ خطای مبهمِ شبکه دیده میشوند.
PATCH /api/user/profile اضافه شد؛ تا پیش از این هیچ راهی برای ثبتِ نامِ
کاربر نبود. GET /api/home بدونِ پارامتر حالا پایهی ذخیرهشدهی کاربر را
برمیگرداند و POST /api/ai/ask فقط با lessonId کار میکند — هر دو برای
اینکه فرانت لازم نباشد پایه را خودش نگه دارد. questionCount به
lessons/{id}/intro اضافه شد.
docs/frontend/api.ts و README.md کلاینتِ تایپدار و راهنمای اتصالاند، از
روی OpenAPI واقعیِ همین سرویس تولید شدهاند.

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.

The skill-map response gave units -> nodes with id/title/status but no way
to map a node to its lessons, and no other endpoint fills that gap
(/api/progress/nodes doesn't either). Any client rendering the map needs
this to know which lesson to open when a node is tapped.
The ids are already computed in the cached _grade_tree; this just surfaces
them. Additive and backward-compatible; content tests pass.

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.
