Writes keep 15s so an early cut does not make the user submit twice. Worst-case boot
wait with an unreachable API goes from ~50s to ~27s (3 attempts + backoff). Not tested
on a real slow network.

friendlyError now shows a server detail only when it is Persian prose (no 'خطای 404', no
DRF English defaults); network errors say 'اینترنت قطع است' (navigator offline) or
'اینترنت کند است' (timeout). The native connecting screen picks the same two wordings from
ConnectivityManager (ACCESS_NETWORK_STATE). Debug build compiles; not run on a device.

Inside the app the web splash is invisible with the new APK (the system splash is still on
top) and icon-only for old APKs, so there is no second picture to switch to. Offline or a
5xx on the main frame: system splash released onto the same icon (288dp drawable) with
'در حال اتصال به اینترنت…', retried every 5s. A slow-but-online load shows nothing extra.
Debug build compiles; not run on a device.

Installed APK sequence was system splash -> white WebView -> web splash -> home. The
activity now holds the system splash (core-splashscreen) until the page calls
TadrisinoAndroid.appReady(), after its first non-boot screen; released after 10s or on a
main-frame load error so a dead site shows the WebView error, not an endless splash.
Older APKs have no appReady and are unaffected. Debug build compiles; not run on a device.

The first second was a blank page, then a splash with the selected companion, then the
home screen. Now index.html carries the splash (icon from the Android launcher, name,
white to match the native window background) and SplashScreen draws the same markup, so
the hand-over from HTML to React shows no change. Not run on a device.

The splash used to stay a fixed 700ms plus a fade, so a fast response still showed it
briefly and jumped away. Now only the matching background shows for the first 350ms;
the splash content appears only if the response has not arrived by then, and once shown
it stays at least 700ms. Not run on a device.
- state/companion.ts: one store for the chosen companion (also in localStorage so splash/login show it).
BrandMark (the orange «π» tile) now shows the companion's symbol (Σ Δ π ω) in its colour; screen-header
mascots, loaders and empty/error states default to it; the assistant is «از {name} بپرس» with its face,
colour and wording; the shop, lesson and quiz «ask» buttons name it; the active tab takes its tint.
- Traits, all client-side and light: Σ sigma keeps a running tally of correct answers in the quiz header;
Δ delta shows a flame «×N» chip and an extra buzz for answers in a row; π pi gives a short solving tip
after a wrong answer; ω omega throws gold confetti at the end of every island whatever the score.
Each companion's «correct» sound is pitched differently; confetti uses its colours. Characters screen
lists each trait.
- android/README.md: what MainActivity.kt has that the installed APK lacks (vibrate bridge, media gesture,
in-app gateway + paysInApp), what to check on a phone after building, signing owner, Bazaar policy note.
Checked in headless Chrome with Sigma, Delta and Omega selected (home, assistant, shop, characters, quiz).

The app hands every outside URL to the phone browser, which sends no Referer, and Zarinpal's StartPay
refuses a request without our domain as Referer («دسترسی از این دامنه مجاز نمیباشد»). Checked against
production on a pending order: no Referer → refused; Referer https://math.tadrisino2.ir/ → forwards to
the bank (sep.shaparak.ir).
- pay.html + src/pay.ts: opened in the phone browser, forwards only to our own
/api/payment/orders/<id>/pay link (anything else is refused), so the Referer is math.tadrisino2.ir.
The app opens it as http:// (the WebView keeps only https on its own host); ArvanCloud moves it to
https, and the link rides in the fragment, which never reaches a server.
- MainActivity.kt (next APK): payment pages (our subdomains, zarinpal, shaparak) stay inside the WebView
and `paysInApp()` tells the frontend to navigate directly. Not built.
Not checked: a full payment on a real phone.

- Shop: subscription perks shown once (each card repeated them, «۳ سوال در روز» twice), plans as selectable
rows with one big buy button, prices as «۷۹۸ هزار تومان», a single clear status card for subscribers.
Checkout inside the Bazaar app offers «کارتِ بانکی» (default) or «کافهبازار» for packs with a SKU;
«بهزودی در بازار» is gone. The gateway opens in the phone browser; status refreshes on return.
- Back button: every back-able level (open sheet, pushed screen, non-home tab, shop list) owns exactly one
history entry created right after the tap; back closes the sheet, then the screen, then returns to Home,
then leaves the app. (A re-pushed trap is skipped by Chrome's history intervention.)
- Sound: AudioContext unlocked on the first touch (it was created after a network wait, which WebView/Safari
keep muted); softer notes, option tick, finish fanfare, streak whoosh. Haptics through the new
TadrisinoAndroid.vibrate bridge when the APK has it, navigator.vibrate otherwise.
- Streak: animated flame with lit / at-risk (grey) / frozen (ice) states on Home and the streak screen,
a companion reminder when the streak is at risk or frozen, and a full-screen «روزِ پیاپی» celebration
after the first lesson of the day (needs backend 9024c6b: streak.activeToday / lost).
- Lessons: intro/example text with inline «۱. … ۲. …» renders as a numbered list (2,250 of 4,469 texts).
- Quiz: duplicate React key on the answer bubble fixed.
- android/MainActivity.kt: vibrate bridge and mediaPlaybackRequiresUserGesture=false. Not built; needs the
next APK from the signing owner.
Checked in headless Chrome against the local backend (shop as a subscriber with the Bazaar bridge stubbed,
back sequences, quiz → streak celebration, frozen state). Not checked on a real phone or in the APK.

- Navigator stage: the next screen mounts hidden under the current one and is revealed only when its
first data has arrived (ScreenGate held by useAsync/useGateHold), at most 450 ms; a thin top bar shows
after 120 ms of waiting. Push slides from the left, back from the right, tabs only fade.
- Session cache (stale-while-revalidate) for screen GETs: revisited screens draw instantly.
- Home map and stats are fetched during the splash, so the first screen arrives complete.
- Entrance pop-ins (mascot, islands, lesson cards) run on first view only, not on every revisit.
- Shop status card shows placeholders instead of a wrong «نداری» while loading.
- Re-tapping the open tab scrolls to top instead of reloading; sheets close with a swipe down.
- Quiz: «۱ از ۴» instead of «۱/۴» (read as a fraction), varied praise, «N تا پشتِ هم درست»,
growth-mindset copy after a weak round, zero-reward tiles hidden.
- Streak: a concrete next step when the streak is 0 or today is still empty.
Checked in headless Chrome against the local backend (frame captures at 150 ms and 700 ms latency,
rapid tab tapping, full quiz run). Not checked on a real phone or iOS Safari.

- Store opens with two choices (subscription / question packs); 3- and 6-month cards
show per-month price and saving.
- Units that need a subscription show a crown badge and open the store; a 402 from
the quiz goes there too. «ادامه بده» skips locked units.
- Profile: subscription card with an animated days-left bar (planDurationDays).
- BrandMark (SVG) on splash, home header and footer; copyright footer; floating math
glyphs on splash. CSS transform/opacity only; honours reduced motion.

First time the project has been built: debug and release both produce an APK.
Release refuses to build without keystore or RSA key.

- ?orderId must be numeric; every id in an API path is encodeURIComponent'd.
- The payment sheet shows success only from GET /payment/orders/{id}; a failed lookup says the
status is unknown instead of "paid".
- A 401 from /auth/refresh is not a sign-out when another tab already stored a rotated token.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- muted text #9e9ec0 -> #727299 (contrast 2.6 -> 4.5 on white); tab labels 11px
- map: chapter titles wrap to two lines instead of being cut off
- reduced-motion respected (MotionConfig + CSS), focus-visible ring,
no pull-to-refresh, short vibration on correct/wrong answers
- src/lib/bazaar.ts: bridge to the Android WebView wrapper; checkout uses
Bazaar IAP only inside that app, Zarinpal everywhere else (unchanged)
- android/: WebView wrapper with Poolakey; written but never built

A 429, 5xx or network failure during token refresh used to sign the user
out. Behind one school Wi-Fi or mobile CGNAT the backend's per-IP refresh
limit was hit, and phone users were sent back to SMS login. Now those cases
keep the session and surface as a retryable error.

- The wait screen counts down to the next heart second by second, fills
the first heart as time passes, shows when all five are back, and asks
the server when the time comes; 'continue' reloads the quiz. Packs and
'ask Pi meanwhile' (asking costs no hearts) are offered as ways on.
- The server now also refuses to finish a lesson/island without hearts
and answers (403 no_hearts); the quiz shows the same screen then.
- Invoices know the two admin-set statuses, canceled and refunded.
- Account deletion waits for all six digits of the SMS code.

- profile shows "User482917" under the name, no copy button
- plan cards start with "N questions a day from Pi (free: M)" taken from the plan itself
- "ورود با حسابِ دیگر" signs out cleanly instead of keeping several accounts on one device
- "حذفِ حساب": SMS code for phone users, typing "حذف" for guests
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- the parents section is gone: no parent login, invite codes or "I'm a parent" button;
"گزارشِ والدین" in the profile shows the week against the previous one (praise line,
six tiles, minutes-per-day and right/wrong-per-day charts, a table of the numbers)
- birth date as day / month / year selects (Jalali, leap Esfand handled) instead of age;
adults (19+) are asked which grade's math they want to learn
- user ID under the name, copyable
- "پرداختها و فاکتورها": every order with invoice number, discount, amount and reference code
- tutor: when the free daily quota runs out, a button to the subscription page instead of "retry"

Measured by rendering every question, option and several tutor answers in
Chrome and comparing the on-screen x of each number (2026-09-29):
- A list inside a sentence ('از −۳ به −۲، −۱، ۰ میرسیم', 'الگویِ ۲، ۵، ۸')
was locked as one left-to-right run, so all 482 read backwards. '،' and
'؛' outside brackets now split the run; sets and coordinates in brackets
stay one run. Locked runs are isolates (isolate-override), otherwise the
comma between two of them was still pulled left-to-right.
- Without MathText 704 of 931 minus signs and 602 of 983 expressions were
misplaced; lesson and island titles, the lesson intro, unit blurb,
notification bodies and ticket messages now go through it.
- The chat box takes its direction from each line's first letter, so a
line of pure math stays left-to-right while typing. A line that starts
in Persian can still show its math reordered inside the box; a textarea
cannot isolate part of its text. The sent message renders correctly.
Four expressions with Persian words inside them ('f(x) = (ریشه دوم x) + ۵۰')
remain ambiguous.
