- 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.

- 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.

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.

- Every screen but home is its own chunk and preloads when the browser is
idle; React and motion get their own long-cached chunks. The app entry
goes from 505 kB (160 kB gzip) to 85 kB (27 kB gzip).
- Quiz prompts, options and lesson examples go through MathText, so
'10 + 3 - 7 - 2' reads from the left; an unpaired bracket at the edge of
a math run stays with the Persian sentence.
- Support lists tickets from GET /support/tickets instead of this
browser's localStorage; a ticket's messages load when it is opened.
- '·' next to a Persian zero read as another digit ('فصلِ ۱ · ۰' looked
like ۱۰۰); a thin bar separates them now. Notification bodies show
Persian digits.
- A root or vertex the model already marked with coordinates is no longer
labelled a second time on top of it.

- Home is now the island path of every unit with one clear Start button on the
current island; the six-card dashboard is gone.
- Start opens /nodes/{id}/quiz (4 questions) instead of one-question lessons, so
an island takes one round instead of ~11. Lessons stay one tap away in the sheet.
- Tutor answers render the backend's validated diagram (plane, number line,
fraction) as React SVG; function expressions go through a small parser, no eval.
- Tedi, the mobile-preview mascot, joins as the fourth companion with all six moods
and an onboarding slide.
- Light polish: 3D buttons, header gradients, warmer page background.

The whole app lived in one 3,071-line App.tsx on a Figma scaffold (60 unused
packages, 45 unused UI components, no type-check). The live site could not
reach the backend, Persian-keyboard digits were erased from the phone field,
guests were signed out after an hour, "mark read" hit a method the server
does not accept (405), and iOS Safari blocked the payment window.
What changed:
- src/ split into api/ (one typed client: timeouts, GET retry, single-flight
refresh, SSE), screens/ (one file each), components/, state/, nav/, lib/.
- The API address is configuration only: public/config.js at runtime, then
VITE_API_BASE_URL at build time, then same-origin /api. No domain in code.
- Responsive shell instead of a fixed 390x844 phone frame; self-hosted
Vazirmatn instead of Google Fonts; strict TypeScript, `npm run build`
type-checks first.
- Everything on the handoff list: tutor answers keep their line breaks, have
thumbs up/down, follow-ups, "from the book" badge, retry, history that
survives tab switches and reloads, "why was I wrong" from a wrong answer
with questionId; question reports; hearts with maxHearts/unlimited and a
no-hearts screen with the refill time; result screen and a visible error
when lesson completion fails; subscription status, badge, discount code
before the gateway and the payment-return message; guest refresh token;
6-digit OTP with resend timer; age saved as a Jalali birthYear; PATCH
read-all; leaderboard refetched on open with "you" highlighted; selected
companion shown across the app; logout that revokes the refresh token.
- New screens for endpoints that had none: profile, streak calendar,
support tickets and bug reports, parents, invite-a-friend (with ?ref=
tracking), guest-to-phone upgrade.
- Browser/phone back button walks the screen stack.
Checked with a headless-Chrome walkthrough against a local backend at
390x844 and 360x740 (fresh guest: onboarding, setup, a full lesson, map,
island sheet, every tab and sub-screen, one real tutor question, reload,
logout): no console errors, no failed API calls. Real SMS login and a real
Zarinpal payment were not exercised.
