Add the confirm-link edge method (auth.email.confirm_link): a new
EmailConfirmLinkRequest/Result fbs table, the transcode const + handler + encoder,
and the backend-client call to the existing /sessions/email/confirm-link endpoint —
it rides Execute under the existing service prefix, so no proto/Caddy change. Add a
language field to EmailRequestRequest and forward it (the backend already seeds it).
Add the NotifyProfile sub-kind + notify.ProfileChanged, published by the confirm-link
handler on a successful link so an in-app session re-fetches its profile when the
email was confirmed in another browser. Regenerated fbs bindings (Go + TS).
Un-hide the Profile email box for guest accounts (hidden={!p.isGuest}): a guest
binds an email to register / sign in, and a returning address opens the existing
merge dialog. Provider linking stays hidden — the Telegram control keeps its
wiring behind a hidden attribute — until the non-guest linking matrix (PR2). The
two linking e2e specs remain skipped (they assume a non-guest login and the
visible Telegram control); update their stale comments.
The finished-game export (GCG + a new PNG of the final position) is one
signed, short-lived relative URL (game.export_url; HMAC-SHA256, 10-min
TTL, BACKEND_EXPORT_SIGN_KEY) resolved against the client's own origin
and delivered by the best affordance each platform has (five on-device
review rounds):
- TG Android/desktop: native showPopup chooser -> native downloadFile
dialog (bridge-only chain, activation-safe).
- TG iOS: app-modal chooser -> OS share sheet with the fetched file
(a popup callback cannot supply the activation the sheet needs).
- VK iOS: VKWebAppDownloadFile for both formats.
- VK Android: the PNG opens in VK's native image viewer, the GCG copies
to the clipboard (the VK Android downloader hangs on any download,
Content-Length/Range notwithstanding).
- VK desktop iframe / desktop browsers: plain anchor downloads.
- Mobile browsers: the OS share sheet (fetch-then-share).
- Legacy TG (< Bot API 8.0): app modal + GCG clipboard, no image option.
The PNG is rasterized on demand by the new internal `renderer` sidecar
(node:22-slim + skia-canvas + baked Liberation/Noto Color Emoji fonts)
executing the SAME ui/src/lib/gameimage.ts the ui project unit-tests;
the backend rebuilds the render payload from the journal +
engine.AlphabetTable, and the device date locale, IANA time zone and
localized non-play labels ride the signed URL. Nothing is stored — the
artifact re-derives from the immutable journal on each GET. The gateway
forwards /dl/* (caddy @gateway matcher extended) behind the per-IP
public rate limiter and serves bytes via http.ServeContent.
Deploy: renderer service in compose + prod overlay + rolling order +
prod push list; TEST_/PROD_EXPORT_SIGN_KEY secrets; the sidecar smoke
runs in the ui CI job. Docs: ARCHITECTURE, FUNCTIONAL(+_ru), UI_DESIGN,
TESTING, deploy/README, renderer/README.
Telegram's native showPopup delivers its callback with no user
activation, so navigator.share (TG iOS) and clipboard writes (TG
Android GCG copy) silently fail from it — the chooser is now always the
app's own modal, keeping the button click's gesture alive for the
delivery APIs.
The data:URL preview modal is dropped: the Android TG/VK long-press
menu mangles data: URLs (dead download, black-screen open, base64
clipboard garbage), so a binary PNG has no working client-side route in
those webviews at all. The image option is withheld there until the
server-rendered signed-URL delivery (Telegram downloadFile /
VKWebAppDownloadFile) lands; the plain web and mobile browsers keep it.
On-device findings by the owner on the test contour (TG iOS, TG
Android, VK Android).
The history header's export button now opens a chooser — Telegram's
native popup inside Telegram, the app's own modal elsewhere — offering
the GCG file and a new client-rendered PNG of the final position
(lib/gameimage, Canvas 2D, lazy dynamic import, zero dependencies):
light theme, classic A..O/1..15 axes, label-free premium fills, and a
fixed-typography per-seat scoresheet with GCG-style move coordinates,
multi-word sub-lines, endgame rack-settlement row, winner trophy and a
hostname + device-locale finish date footer; a long game stretches the
board, never the typography.
Delivery mirrors the GCG rules (Web Share with no blob fallback, else
download) except on Android Telegram/VK WebViews and the desktop VK
iframe, where a binary PNG has no clipboard-text fallback: those get a
preview modal with a long-press/right-click save hint and a copy-image
button where ClipboardItem exists.
Landscape fits the whole board, so the coarse-pointer auto-zoom on tile
placement, drag hover-hold and hint only hid the rest of the position.
Gate all three on portrait; manual double-tap/pinch zoom is unchanged.
New e2e lock both sides: landscape placement stays unzoomed, portrait
placement still auto-zooms (touch-emulated, both engines).
The landing now always opens in Russian (saved 🌐 choice still wins) —
browser-language detection made the indexed content nondeterministic
(Googlebot renders with en-US). landing.html gains the static Russian
SEO head: title/description, canonical pinned to the production origin,
Open Graph card (Telegram/VK link previews), twitter:card, JSON-LD,
theme-color and the favicon set; the SPA shell turns noindex and its
tab title becomes «Эрудит (Скрэббл)». New assets/icons generator
(same tile design as the VK loader) produces favicon.svg/ico,
apple-touch-icon.png and og-image.png into ui/public/, plus robots.txt.
The small 1️⃣ in the status bar's score-preview slot read as noise; the
single-word rule keeps its spelled-out label in the history header and
the lobby invitation card.
Add the VK Mini App logo next to the Telegram one on the landing hero,
linked via the new VITE_VK_APP_LINK build-arg (full URL, wired through
compose, CI and prod-deploy from TEST_/PROD_VITE_VK_APP_LINK).
Also restore the landing's Telegram link itself: commit 57c778f
collapsed the per-language vars to VITE_TELEGRAM_GAME_CHANNEL_NAME in
compose/CI but left gateway/Dockerfile with the stale _EN/_RU ARGs and
without the plain one, so the built bundle saw the var as undefined and
dead-code-eliminated the whole channel-link branch — deployed landings
(prod included) have shown no Telegram logo since.
The Android VK client's WebView ignores target=_blank and navigates the
Mini App's own window to the target, stranding the player outside the
game with no way back (the dictionary lookup, About/Feedback links, the
ad banner and the bot-link modal fallbacks). vk-bridge 3.x has no method
to open an external URL, so external links are routed through VK's own
leave-VK redirect (vk.com/away.php), which the client intercepts
natively and hands to the system browser.
onExternalLinkClick moves from lib/telegram to a new lib/links that
composes the Telegram and VK routers; iOS and desktop VK open _blank
correctly and are left alone.
Measure uptake of the client-side local move-preview accelerator (§5) so
adoption can be watched before defaulting it on: app cold starts, dictionary
loads by result (fetched / cache_hit / miss) and move previews by path
(local / network — the backend load shed).
A small best-effort client beacon (POST /metrics/local-eval, session-gated)
batches counter deltas and posts them on a 60s timer and when the app is
backgrounded — never on the gameplay path: the in-app counters are plain
in-memory increments, only the periodic flush touches the network and it is
fire-and-forget. The gateway folds each batch into three OTel counters
(local_eval_cold_start_total, local_eval_dict_load_total,
local_eval_preview_total), clamped against a spoofed inflation.
- gateway: counters + recordLocalEval + session-gated /metrics/local-eval handler
- ui: localeval-metrics accumulator/beacon; hooks in the dict loader, in
Game.recompute and in bootstrap (skipped under the mock harness)
- caddy: route /metrics/* to the gateway
- docs: ARCHITECTURE §11; Grafana "Scrabble — Users" dashboard panels
Score and validate a tentative move on-device instead of a per-arrangement network
round trip. The dawg reader and the validate/score/direction slice of the
scrabble-solver engine are ported to TypeScript (ui/src/lib/dict), pinned
byte-for-byte to the Go engine by a `conformance` CI job (full-dictionary reader
parity plus a battery of plays across every variant and both cross-word rules,
including the inferred orientation). The server stays authoritative — submit_play
re-validates — so the local result is an advisory accelerator only.
- backend: Registry.DictBytes + an authed GET /api/v1/user/dict/{variant}/{version}
(immutable) streaming the pinned per-game dawg; caddy routes /dict to the gateway.
- gateway: a session-gated /dict edge route proxying it; fetchDict on the transport.
- client: the dictionary loads on game open (low priority so it never starves the
game on a slow link; aborted at a 5s cap or when leaving the game), is cached in
IndexedDB (best-effort, self-healing on a rejected blob) and reused across
sessions; a warm-up overlay covers a cold load, then the network preview is the
fallback; a bad-connection breaker stops warming after repeated misses; the move
preview cancels its in-flight request when the tiles change.
- parity generators backend/cmd/{dictgen,validategen} + gated Vitest suites, run in
CI against the release dictionaries. A hidden debug readout lists the cached
dictionaries + breaker state, and its reset clears the cache.
- docs: ARCHITECTURE §5, TESTING, UI_DESIGN, FUNCTIONAL (+ru).
The production UI build shipped `.map` files with full `sourcesContent`, and
the gateway/landing images serve `dist/` verbatim, so anyone could fetch
`/app/assets/main-*.js.map` (same assets under `/vk/`, `/telegram/`) and
reconstruct the entire TypeScript/Svelte source at the edge.
Gate `build.sourcemap` off for `mode === 'production'` (the Docker image build).
Dev and the `mock` e2e build (`vite build --mode mock`) keep maps for debugging.
Document the posture in ARCHITECTURE.md §12.
Parity with the Telegram chrome painting: on a VK Mini App launch and on
every theme change, set VK's status-bar appearance (and, on Android, the
action/navigation bar colours) from the app's live theme tokens, so the VK
chrome matches the UI instead of clashing.
syncVKChrome mirrors syncTelegramChrome; the status-bar appearance is
derived from the --bg token's luminance (appearanceForBg, unit-tested).
Wired into the VK onScheme handler (fires on launch + on theme change) and
setTheme. Docs: UI_DESIGN VK integration.
On-device diagnostics from Android Telegram and VK confirmed both expose
no navigator.share AND no navigator.canShare, so the export fell to a Blob
<a download> that those WebViews silently ignore — nothing happened.
pickGcgDelivery is now a 3-way decision: Web Share where available (iOS),
a clipboard copy in an Android in-app WebView (Telegram/VK: no share, dead
download), else a desktop Blob download. shareOrDownloadGcg reports the
outcome so the game shows a "GCG copied" toast; the copy is VKWebAppCopyText
inside VK (which also covers the desktop VK iframe, where navigator.clipboard
is blocked) and navigator.clipboard otherwise.
Unit tests cover the 3-way choice and the copy/failed outcomes; new i18n key
game.gcgCopied (en+ru); docs ARCHITECTURE/FUNCTIONAL(+ru)/UI_DESIGN/TESTING.
The global -webkit-tap-highlight-color on #app was not enough on Android
in-app WebViews (Telegram, VK): they only suppress the selection-like tap
flash when -webkit-user-select / -webkit-tap-highlight-color /
-webkit-touch-callout sit DIRECTLY on the tapped element, not inherited.
Set them on the two tappable header controls — the title (a 10-tap debug
target) and the back chevron.
- Tap-highlight: add -webkit-tap-highlight-color: transparent on #app.
Android in-app WebViews (Telegram, VK) flashed a momentary selection-like
box on tappable nodes on tap — seen on the header title and the back
chevron; user-select (already none) does not govern it. Inherited, so
this clears it app-wide.
- VK haptics: mirror the Telegram haptic set on VK via VK Bridge taptic
(impact / notification / selection), routed through a new shared
lib/haptics.ts dispatcher. VK users previously got no haptics; the game
and error call sites now fire haptic() instead of telegramHaptic().
- VK swipe-back: disable VK's horizontal swipe-back at launch
(VKWebAppSetSwipeSettings history:false) so it does not fight the app's
own edge-swipe-back and on-board tile drag — parity with Telegram's
disabled vertical swipes; the app owns navigation via its back chevron.
Docs: UI_DESIGN (no-select / tap-highlight, VK integration).
A one-time coachmark overlay walks a new player through the lobby and their
first game board: a light dimmed layer draws one tail-pointed hint bubble at a
time, advancing on a tap anywhere and removing itself for good after the last
hint. Two independent series (lobby: settings/stats/new game; game:
header/pass-exchange/hints/shuffle/rack), gated by a per-device persisted flag
and marked done only after the last hint, so an interrupted run replays from
the start. A deep-link into Settings -> Friends still triggers the lobby series
on the first trip back to the lobby.
Targets carry a data-coach attribute, so one positioning engine anchors the
bubble in both portrait and landscape, re-measuring each frame until the
geometry settles (route slide, hidden-banner reflow, fonts). The promo banner
hides while the overlay is up (app.coachActive); a hidden DebugPanel "Reset
visited" control replays the walk-through. Off by default in the mock build so
the Playwright smoke is unaffected; ?coach forces it on for the dedicated e2e.
Pure geometry (step lists, nextVisibleStep, placeBubble) in lib/coachmark.ts
(unit-tested); Coachmark.svelte renders. Docs: FUNCTIONAL(+ru) onboarding
story, UI_DESIGN coachmark section.
The contour diagnostic confirmed VK forwards only the signed vk_* params to the iframe — a
custom payload on the app link is dropped (the '#' eaten by the vk.com SPA, a '?' query
stripped), so the friend-code cannot ride the link. The VK share link is now just
vk.com/app<id>; the recipient enters the copied code by hand (VKWebAppCopyText works). The
vkStartParam reader + bootVK routing stay as a no-op, ready for a post-moderation channel.
Removes the temporary deep-link diagnostic.
Contour review of the VK Bridge group:
- #6 invite link: VK's documented '#' direct-link payload is eaten by the vk.com SPA before it
reaches the app, so the friend-code link now carries the payload as a query param
(vk.com/app<id>?hash=f<code>); the recipient already reads the `hash` query param (vkStartParam).
(Whether VK forwards the '?' through to the iframe is being confirmed on the contour.)
- #8 Android: the VK mobile webview does not surface the home-bar inset via CSS env() (config
insets are iOS-only), so subscribe to the bridge insets (VKWebAppUpdateConfig + VKWebAppUpdateInsets)
and set --tg-safe-* to max(env(), the VK value).
- #8 landscape colour: the home-indicator strip was the (grey) page background because the two-pane
landscape game has no bottom bar. The left-panel controls bar now paints its own chrome into the
inset (Screen gains a selfInset flag that drops the shell's detached padding strip), and the
game-land runs flush to the edge.
Verified: svelte-check, 347 unit, build, bundle-gate; the landscape safe-area painting reproduced in
the mock (controls bar + board reach the edge, strip takes the bar colour). The VK-Bridge / VK launch
behaviours (Android insets, the ?hash forward) need the live contour.
Group B of the VK integration — the contour-verified follow-up to the launch+auth MVP:
- Share/copy inside the VK iframe go through VK Bridge: the friend-code invite shares via
VKWebAppShare and copies via VKWebAppCopyText, since navigator.share is absent in the desktop
iframe and navigator.clipboard is blocked there.
- The invite link is a VK Mini App direct link (vk.com/app<id>#f<code>) on VK instead of the
Telegram link; the app id comes from vk_app_id in the launch params (no build arg needed). The
recipient's launch routes the deep link from VK's `hash` launch query parameter.
- The app's "auto" theme follows the VK client's light/dark appearance (VKWebAppUpdateConfig),
which the VK mobile webview's prefers-color-scheme does not track.
- The safe-area CSS vars default to env(safe-area-inset-*), so the VK mobile layout clears the
home bar (and Capacitor/PWA too); Telegram still overrides them from its SDK.
vk.ts adds vkAppId/vkStartParam/vkShare/vkCopyText/vkOnScheme. Verified: svelte-check, 347 unit
(+ vkAppId/vkStartParam/vkShareLink), build, bundle-gate. The VK-Bridge behaviours need the live
contour (not reproducible headless).
Follow-up to the contour review: with the rack now exactly seven fixed-size slots in the
narrow landscape panel, the 56px confirm button (sized for the roomy portrait rack) was
wider than the single slot a staged tile frees, so it overlapped the now-rightmost tile.
Match the button width to one landscape tile slot, so it sits inside the freed slot with
its right edge level with the rack's right edge — the mirror of the first tile's left edge.
Follow-up to the contour review of the landscape fixes:
- Zoom still positioned "in two steps": a wide viewport overflows vertically as soon as
the square board grows past its height, but horizontally only once it grows past the
(much wider) width — so the browser pins scrollLeft to 0 while the vertical axis
already pans (no time/ease tween fixes it; the horizontal scroll range physically is
not there yet). Found by instrumenting the scroll trajectory. Now drive both axes by
one progress = how far the board has grown past the viewport width (when a horizontal
pan first becomes possible): until then the board just zooms centred, past it both
axes pan together in one diagonal motion. Also disable scroll-anchoring so the browser
stops fighting the programmatic scroll mid-transition. Re-verified: both axes now
start and move together.
- Rack tiles resized when a tile was placed: landscape used flex-grow, so removing a
tile regrew the rest. Give them a fixed size (1/7 of the fixed-width rack), like the
portrait rack, so placing a tile leaves the rest put.
Bugs surfaced while testing in VK but present on every platform (verified across
browsers, not VK-specific):
- Rack tiles: the letter used a fixed rem size, so in landscape — where tiles shrink
below 46px in the narrow left panel — it overflowed and dropped into the bottom-left
corner. Size it relative to the rack (cqw, like the board's labels; the tile's own
container-query size resolves unreliably under flex + aspect-ratio).
- Landscape board zoom positioned "in two steps": the per-frame clamp-to-max reached
the wide axis before the tall one. Interpolate both scroll axes together by time over
the grow/shrink transition instead (settles on zoom-out too).
- The zoomed board could not be panned with a mouse (touch scrolls the overflow:auto
viewport natively; a mouse cannot drag-scroll a div). Add a drag-to-pan handler, active
only while zoomed, off pending tiles, past a small movement threshold, swallowing the
trailing click so it does not also act on a cell.
- Shorten the in-game block-confirm label ru "Блокируем?" -> "В бан?" (the long form
overflowed the seat score chip on mobile).
Mirror the Telegram Mini App wrapper for VK: the SPA loads at a new /vk/
entry, authenticates from VK's signed launch parameters, and provisions a
'vk' platform identity — the minimum to run the game in VK test mode.
- Gateway verifies the launch signature in-process (internal/vkauth:
HMAC-SHA256 over the sorted vk_* params under GATEWAY_VK_APP_SECRET,
base64url) — a pure offline check, no side-service. New auth.vk op
(gated on the secret), backendclient.VKAuth, /vk/ SPA mount.
- Backend: KindVK + ProvisionVK/vkSeed, /sessions/vk handler, identity
kind widened to include 'vk' (migration 00005, expand-contract).
- UI: src/lib/vk.ts (VK Bridge, lazy-imported), bootVK + the /vk/ boot
dispatch, encodeVKLogin + authVK across transport/client/mock. VK omits
the name from the signed params, so the client reads it via
VKWebAppGetUserInfo as an unsigned display seed.
- Deploy: /vk in the edge Caddyfile, GATEWAY_VK_APP_SECRET wired through
compose + .env.example + CI (TEST_) + prod-deploy (PROD_).
- Admin console: surface the VK user id (link to the VK profile) next to
the Telegram id on the user card.
- Docs: ARCHITECTURE §12/§13, FUNCTIONAL (+ _ru), gateway README; VK
integration reference under .claude/.
Signature algorithm verified against dev.vk.com plus independent Node/Python
references and a %2C edge-case vector.
The stale-invite / welcome-on-redeem notices are raised during boot, so the native
popup fired over the loading splash. Gate both the native popup and the in-app Modal
on the current route's loading cover being gone — the tile splash on the lobby
(splashDone), the plain loading screen elsewhere (app.ready) — so the notice appears
with the settled screen on every build (Telegram and native/web alike).
The deep-link info modals (stale invite, welcome-on-redeem) captured
insideTelegram() && telegramDialogsAvailable() in a const at component init, but they
mount in App before bootstrap loads the SDK, so the value was always false and they
fell back to the in-app Modal even inside Telegram. Evaluate it at fire time (in the
effect and the {#if} guard), as the destructive confirms already do at click time.
Inside the Mini App, route the destructive confirmations (resign, block, unfriend)
through Telegram's native showConfirm, and present the deep-link info modals (stale
invite, welcome-on-redeem) as a native showPopup whose button opens the bot chat.
Outside Telegram, or on a client predating the dialogs, the existing in-app Modal is
used unchanged; offline also keeps the modal so the action retains its disabled state.
Adds showConfirm/showPopup wrappers to telegram.ts and a pure popup-params builder
(nativedialogs.ts) with unit tests; the deep-link modal components choose native vs
in-app via an effect gated on insideTelegram + dialog availability.
Theme, reduce-motion and board labels lived only in local IndexedDB/localStorage,
so they did not follow the user across devices and could be lost when the Telegram
WebView cleared storage.
Mirror these three device-independent prefs to Telegram CloudStorage (Bot API 6.9)
from the single local-persist point (persistPrefs), and reconcile them from
CloudStorage in the background on launch (reconcileCloudPrefs) so a change made on
another device follows the user here. The local store stays the instant-render
cache; the interface language is intentionally excluded (it syncs via the durable
account). Pure encode/decode extracted to cloudprefs.ts with unit tests; the
CloudStorage transport wrappers are added to telegram.ts. No-op outside Telegram or
on a client predating CloudStorage.
Inside the Mini App, reveal Telegram's native Settings button (Bot API 7.0)
and route its taps to the Settings screen — the standard Mini App affordance.
The in-app gear entry stays the primary path (two entry points by design).
No-op outside Telegram or on a client predating the button.
The safe-area bottom inset was reserved on the Screen wrapper, so the strip
that holds space for the home indicator showed the content background and read
as detached from the coloured bottom bar / header above it.
Move the bottom inset onto the bottom bar: the Screen .tabbar wrapper now paints
--bg-elev and pads itself by --tg-safe-bottom, so the strip continues the
TabBar's chrome; a screen with no tab bar pads its bottom-most content
(.content:last-child) instead, so the strip takes that content's own colour.
Only the device safe-area TOP inset was mirrored, so on phones with a home
indicator the rack / bottom bar sat under it, and in landscape the notch
clipped the screen edges.
Mirror the full device safe-area inset (bottom / left / right) into new
--tg-safe-bottom / --tg-safe-left / --tg-safe-right CSS vars (0 outside
Telegram) and pad the shared Screen wrapper by them, so every screen clears the
home indicator and the landscape notch; the top inset stays owned by the header.
Replace telegramSafeAreaTop with telegramSafeAreaInset (the full inset object),
with a unit test.
The Mini App read Telegram's themeParams/colorScheme only once at launch, so
switching Telegram's light/dark theme (or its auto day/night) while the app was
open left the SPA on stale colours until a relaunch.
Subscribe to the themeChanged WebApp event and re-apply the theme live. Extract
the launch-time token + colour-scheme + chrome application into syncTelegramTheme
(reading live themeParams when no launch snapshot is passed) and call it from both
applyTelegramChrome (launch) and the new event handler. Add a telegramThemeParams
live getter (+ unit test). Drop the stale 'immersive fullscreen' note from
applyTelegramChrome — the app deliberately does not request fullscreen.
The custom title bar was too tall. Halve the standard bar padding (10->5px) and, in the Telegram path, the notch gap (16->8px) and bottom (6->3px); the notch safe-area inset is unchanged. Title and back chevron stay vertically centred.
The share button uses the OS Web Share sheet outside Telegram (the TG share picker only inside it), so "via Telegram" was misleading. Rename to a neutral "Share"/"Поделиться" and drop the now-unused tgshare class.
Finalises the Telegram Mini App navigation work after on-device testing (Pixel
10 / Android 17 + iOS, fresh beta clients):
- Remove requestFullscreen entirely. Immersive fullscreen hid Telegram's native
header (and its BackButton) and the Android system swipe-back minimised the
app; the owner prefers the windowed full-size (expand) presentation, so the
app never requests fullscreen on any platform now.
- The app's own back chevron (Header, showBack = !!back) drives back-navigation
on every platform; the native Telegram BackButton is dropped — it does not
render in the windowed Mini App (backVisible=false on iOS and Android), so
relying on it lost back navigation (notably none on iOS).
- Replace the temporary always-on diagnostic overlay with a hidden debug panel
(components/DebugPanel): ten quick taps on the header title open it; it shows a
privacy-safe client diagnostic snapshot (app version, locale, online, userId,
Telegram chrome / viewport / SDK state — no secrets, no IP) and shares it via
the OS share sheet / clipboard; a tap anywhere except Share dismisses it.
- Drop the now-dead telegramRequestFullscreen / telegramBackButton /
isTelegramAndroid helpers and the iOS-fullscreen unit test.
Telegram has no native non-modal notification API (only modal showPopup /
showAlert), so in-app toasts stay ours. Docs: UI_DESIGN.md.
The Telegram native BackButton does not render in the windowed Mini App (the
owner's emulator + a fresh beta TG report backVisible=false on both iOS and
Android), so relying on it lost back navigation — iOS had no back affordance at
all. Show the app's own back chevron whenever there is a back target, on every
platform (Header showBack = !!back), and drop the now-dead native BackButton
effect (App.svelte). The native close control stays — a windowed Mini App
cannot hide it (no Telegram API).
WIP: the temp lobby diagnostic overlay and the requestFullscreen no-op remain
for the owner's emulator test; finalize after confirmation.
WIP for the Android nav investigation (TEMP bits reverted before merge):
- telegramRequestFullscreen: temporarily a no-op (incl. iOS) so the owner can
confirm the Android "fullscreen look" is Telegram's own Mini App presentation,
not our requestFullscreen (isFullscreen is already false on Android).
- Header: show the app's own back chevron in Telegram on Android, where the
native BackButton does not render — a reliable tap-back. [keep]
- Diagnostic overlay moved app-wide (pointer-events:none) and now reports
BackButton state (req/present/visible) + viewport geometry, to see whether the
native BackButton can capture the Android system swipe-back.
Renders Telegram viewport/fullscreen state (isFullscreen, isExpanded, viewport
heights, innerH vs screenH, safe-area insets) in the lobby, inside Telegram
only, to diagnose why the app still opens fullscreen on Android with
requestFullscreen now iOS-only and no persisted state (fresh TG + test account).
REVERT before merge.
Three Android Mini App issues, all in the Telegram chrome:
- Entering a game showed no native back button, and the Android system
swipe-back minimised the app instead of navigating. Root cause: immersive
fullscreen (requestFullscreen). On Android, fullscreen replaces the native
header — and its BackButton, which also captures the system back — with a bare
close/menu pill, so back navigation has no control to land on. Request
fullscreen on iOS only; Android stays windowed, keeping the native header +
BackButton (and the system swipe-back that routes to it). iOS is unchanged.
- Closing the game board always prompted "changes that you made may not be
saved", even on a board just opened and untouched. The close-confirmation was
armed unconditionally on game mount. Remove it entirely: move drafts auto-save
(debounced during play + flushed on destroy), so nothing is lost on close.
Drops the now-unused telegramClosingConfirmation + isMobilePlatform helpers and
their SDK interface fields. Docs: UI_DESIGN.md.
The diagnostic showed only sdk: yes/no (window.Telegram presence), not why the
SDK was absent. Capture how the dynamic telegram-web-app.js load resolved —
present / loaded / no-webapp / error / timeout — and surface it as
"sdk-load: <outcome>". error/timeout pinpoint a blocked or hanging telegram.org
(the prime suspect for an empty launch); no-webapp a loaded-but-broken script.
loadTelegramSDK records the outcome (telegramSdkOutcome); collectTelegramDiag
carries it into the screen. Unit tests cover each outcome; the blocked-script
e2e now asserts sdk-load: error.
The Telegram SDK was a render-blocking <script src="telegram.org/..."> in the
shared index.html shell, so it ran on every entry (/telegram/, /app/, native).
On a network that blocks telegram.org — common where Telegram itself reaches
users only over a proxy — the script hangs forever, stranding the whole page,
including the launch-diagnostic screen meant to surface exactly this failure.
This is the likely root cause of the Android "won't open" reports (all launch
methods fail identically; iOS on a different network works).
Remove the head <script> and load the SDK dynamically (lib/telegram.ts
loadTelegramSDK) with a 10s timeout, only on a Telegram entry (the /telegram/
path or a tgWebApp launch fragment). The SPA — served from our own reachable
origin — boots first and controls the load: on a block/error it falls through
to the diagnostic screen (reporting sdk: no) instead of hanging, and Retry
re-attempts. /app/ and the native build no longer touch telegram.org.
Pin the SDK to the version the official page recommends (?62) for the newer
client features the app already uses (fullscreen, safe areas, swipe guard).
Tests: loadTelegramSDK unit tests (present / error / timeout); an e2e that
aborts the script fetch and asserts the diagnostic still renders.
A Mini App launch on /telegram/ without sign-in data (empty initData) used to
location.replace('/') — bouncing the visitor to the marketing landing. That
destroyed all diagnosability and, on some Android clients that reach the entry
with no initData, simply looked like the app refusing to open.
Replace the bounce with a compact, privacy-safe launch-error screen
(screens/TelegramLaunchError.svelte) that renders a one-screenshot diagnostic
snapshot captured at the moment of failure: SDK/WebApp presence, Telegram
platform/version, whether initData is empty, whether the URL fragment carried
tgWebAppData, the initData field NAMES present/missing (never the signed
values, never an IP), and OS/mobile/browser via User-Agent Client Hints plus
the full User-Agent. A Share button delivers it through the OS share sheet
(clipboard copy on desktop, reusing the GCG no-webview-strand guard); Retry
re-checks in place to recover a late initData without a reload (which would
discard the launch fragment).
This is the instrument to root-cause the Android empty-initData failure, which
is not reproducible in Playwright.
Tests: collectTelegramDiag + shareText/pickTextShare unit tests; the /telegram/
e2e now asserts the diagnostic screen, not a redirect. Docs: ARCHITECTURE.md +
UI_DESIGN.md updated.
Cover the reworked Settings -> Friends interactions in the mock e2e
(Chromium + WebKit): the row kebab slides open the block/remove icons and an
outside tap collapses it; blocking confirms (naming the friend) and moves them
to Blocked; removing confirms and drops the friendship.
