7ecb337263 Finishing a lesson or island needs recorded answers and an unlocked island; auto DB backup before migrate; throttles on 15 more routes
- 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.

663252a260 Remove the guest system entirely: no is_guest/device_id, no guest throttles, phone login is the only way in
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.

ab5e53730a Audit fixes 2026-10-03: seed keeps admin edits, plan cache, refresh limit, payment and tutor guards
- 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

7307bfcadb Remove silent fallbacks found in the 2026-10-03 audit
- /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.

42783f9ba4 tutor answers step by step in plain text, islands finish, and the audit's money and login holes are closed
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.

5f3aae0756 cover the new paths, especially the ones that fail silently
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.

a275eac7fd fix heart refill and grant unlimited hearts to active subscribers
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.

35218bf6a1 fix HomeView N+1 and cache the curriculum tree
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.

149f1ad9ae return mascotMood on answer submission
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.
