- technical-handbook: question packs instead of subscriptions, real
hearts with the new wait screen (screenshot), math-only tutor and what
is charged (new 9-7), admin cancel/refund, Bazaar planId, account
deletion, 59 endpoints, 779 tests, 14 apps, status and open decisions.
- Diagrams redrawn: use-case (buy a pack, refunds), data model
(QuestionCredit, HeartsPass, Profile.birth_date), pack payment sequence.
- The PDF is now built from the Markdown by docs/build_handbook.py
(pandoc + Chrome, font in docs/assets); the hand-made HTML it used to
come from was not in the repo and had been lost.
- architecture, operations, security-before-production (item 13 closed),
ai-cost-and-guardrails and README follow the same changes.

- 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

The API moved to mathapi.tadrisino2.ir on 2026-09-26 (nginx server_name
changed at 23:22) and api.math.tadrisino2.ir no longer resolves. The code
default for PUBLIC_BASE_URL and the docs' curl examples still named the dead
host, so every paymentUrl, the Zarinpal callback and the Bazaar redirect the
backend builds pointed nowhere. Historical status notes in CLAUDE.md keep the
old name on purpose. config/tests.py now reads the API host from
PUBLIC_BASE_URL instead of a literal. 624 tests green.

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.

docs/security-before-production.md records, item by item, what is exposed
on purpose while this is an internship demo: the committed token-signing key
still in use on the server, seven fixed-code demo logins, demo users in the
production database, a public /api/health that reports internal state, a
public API schema, a public leaderboard with children's names, /admin on the
public domain, the server answering on port 80 around ArvanCloud, per-worker
rate limits without Redis, guest login by deviceId alone, unhashed refresh
tokens and OTP codes, AI cost exposure through throwaway guests, hearts not
enforced, SQLite without off-box backups, and shared root access to the box.
Each has its risk, why it was left, the fix and how to verify it; the
exposure checks were run against the live server on 2026-09-25.
CLAUDE.md, README and docs/operations.md point to it so no agent mistakes
this deployment for production-ready.
