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 deploy-check skill is repo-specific: it encodes this project's hard-won
pre-deploy runtime constraints (distroless nonroot, edge Alt-Svc/HTTP3, caddy
recreate, DICT_VERSION boot, expand-contract migrations, the Telegram permission
model) and points at deploy/README.md, docs/ARCHITECTURE.md, docs/EDGE_HTTP3.md and
the agent memory files. It belongs with the deploy logic it guards, not in the global
config, so it travels with the repo and stays versioned alongside it.
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.
Record the current state in ARCHITECTURE and FUNCTIONAL (+ _ru mirror): inside the
Mini App the client tracks Telegram's live theme switch, fits the full device
safe-area, exposes a native Settings button into the in-app settings, and syncs the
device-independent display prefs (theme, reduce-motion, board labels — not the
interface language) across the user's Telegram devices via CloudStorage; the
validator denies a bot user (is_bot) before provisioning an account.
The validator parsed only id/username/first_name/language_code from the signed
Telegram user, so a WebAppUser flagged is_bot would have been provisioned a normal
account. The HMAC already proves Telegram signed the payload, so is_bot==true is
Telegram itself attesting the launching principal is a bot.
Parse is_bot and reject it (ErrInvalidInitData -> gateway 4xx -> launch error). A
real user opening the Mini App never carries it, so this is a defensive deny. Tests
cover both the denied (is_bot true) and allowed (is_bot false) paths.
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 promo message body now renders "@<bot>" as an HTML text_link to the same ?startapp deep link the button uses (ParseMode HTML), so tapping the mention opens the seeded Mini App instead of the bot profile. Same payload (campaign start-param, else the forwarded /start payload) backs both the button and the mention.
The promo bot button carries a configurable variant-seed start-param (default verudit_ru-scrabble_en). The gateway parses start_param from the validated initData and forwards it; the backend, on first contact only, seeds the new account variant_preferences from it (English Scrabble alongside the default Erudit).
No schema change (the scrabble_en CHECK is already in the baseline) and the gateway<->backend REST field is additive, so the rolling deploy is safe in either order. TELEGRAM_PROMO_START_PARAM configures the payload (empty forwards the user own /start payload). Covered by account unit tests, a gateway transcode test, and an integration test asserting new-only seeding.
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.
Telegram silently routes a copyMessage aimed at a deleted forum topic
into the chat's General topic with NO error, so the bot's error-based
recreate never fired — the user's next message landed in General with no
card. Confirmed against the prod bot logs: a relay after a topic deletion
logged neither "relay to topic failed" nor "topic gone, reopening".
Probe topic liveness before reusing it: re-applying the info card's reply
markup is a no-op that errors only when the card (hence the topic) is
gone, so the bot detects the deletion and reopens the topic + card rather
than relying on the (absent) copy error. The post-copy recreate stays as
a race backstop.
The topic info card built the profile link as `tg://user?id=`, which
clients render as dead text for a user they don't already know (the
test-vs-prod difference an operator saw), and it put the raw display
name through HTML — so a name starting with "/" was auto-detected as a
tappable bot command that fired when tapped.
Render the card with message entities instead: the display name is
covered by a `text_mention` entity (the reliable way to mention a
username-less user the bot has already seen — it messaged the bot),
which links the profile AND, because the name sits inside an entity,
suppresses the "/command" and "@mention" auto-detection on it. Drop the
HTML parse mode and the tg:// link. Entity offsets are UTF-16.
Users who DM the bot anything but /start are relayed into a private
forum supergroup, one topic per user. Operators (the chat's admins)
reply in the topic and the bot copies it back to the user; an info card
opening each topic carries a Block/Unblock toggle and a Clear button.
State is a small JSON file on a new /data volume — the bot host has no
database. Off by default (TELEGRAM_SUPPORT_CHAT_ID=0): the prod bot is
unchanged until the operator sets the chat id and adds the bot as a
forum admin.
- internal/support: concurrency-safe JSON store (topic map, block list,
relayed message ids) with field-targeted mutators and atomic save
- bot/support.go: relay both ways via copyMessage, short-TTL admin
cache, callback buttons, per-user topic-create lock, loop guard
(skip the bot's own posts), reopen a deleted topic on the next message
- config + compose + CI/prod-deploy: TELEGRAM_SUPPORT_CHAT_ID per
contour + TELEGRAM_SUPPORT_STATE_DIR; bot-state named volume; /data
pre-owned by UID 65532 so a fresh volume is writable under distroless

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.
A slid-open friend row now collapses when the user taps anywhere outside its
action buttons (taps on a kebab are skipped so its own toggle still drives the
open/close). Uses the same capture-phase window pointerdown idiom as Screen,
active only while a row is revealed.
Settings -> Friends previously rendered each friend as a bordered card with
two always-visible text buttons (Remove / Block) that fired immediately. Rework
the whole screen to the lobby's visual language: one-line rows split by
hairline separators across all three sections (friends, incoming requests,
blocked).
Each friend row gains a right-hand kebab that slides the row open to reveal two
icon actions split by a vertical divider -- block (no-entry) and remove (cross)
-- mirroring the lobby's slide-to-reveal. Both actions now require a
confirmation modal; since the slide moves a short name off-screen, the modal
keeps a generic title and shows the friend's name in the body, above the
buttons, so a long name cannot stretch the sheet. Incoming keeps its
accept/decline buttons and blocked keeps unblock, inline on their rows.
Add the friends.actions / friends.blockConfirm / friends.unfriendConfirm keys
to both i18n catalogs and document the flow in FUNCTIONAL (+_ru).
The prod rolling deploy rolls each service with `compose up -d --no-deps <svc>`.
For caddy that is a no-op on a config-only release: its image is pinned
(caddy:2-alpine, no $TAG), so the compose definition is unchanged between
releases, compose treats the container as current and does not recreate it, and
admin is off so there is no hot reload. The new bind-mounted Caddyfile is seeded
to the host but never loaded -- the v1.2.2 `Alt-Svc: clear` edge fix deployed
green yet did not take effect until caddy was restarted by hand.
Force a recreate for caddy on its roll (every other service already recreates on
its new $TAG image), so a bind-mounted Caddyfile change always applies. Costs a
~1-2s caddy blip per deploy, acceptable for the infrequent manual prod rollout.
The "Database size" stat had no thresholds, so Grafana applied its stat
default (green base, red at >=80). The query is pg_database_size_bytes, so a
healthy ~9 MiB database (9.4M >> 80) rendered permanently RED on the
Scrabble - Resources dashboard (test + prod), reading as a false alert; the
neighbouring percentunit cache-hit stat stayed green only because its 0..1
values fall under 80.
Add absolute byte thresholds sized to the 40 GiB prod disk (4.6 GiB used,
observability bounded -- Tempo <=1 GiB, Prometheus 7d -- so the DB is the
only unbounded grower): green up to 8 GiB, yellow at 8 GiB (~20% of disk),
red at 16 GiB (~40%), an early warning with ample runway before the disk
tightens, not a panic line. Cosmetic panel coloring only; there are no
Grafana alert rules provisioned.
