Robokassa moderation requires the public offer to list every digital good with
its price. Move /offer/ off the static landing container to the render sidecar:
it splices the live catalog price list (§4.4) into the owner-edited
ui/legal/offer_ru.md and renders it with the shared ui/src/lib/offer.ts — one
renderer, no drift, always matching the current catalog with no redeploy.
- backend: /api/v1/internal/offer/pricing (internal, off the edge allow-list)
projects the active catalog into two markdown tables — chip packs priced per
rail (roubles / VK votes / Telegram Stars) and chip-priced values — through
payments.Money so no float reaches the page. Cached in memory: warmed at boot,
marked stale on every catalog mutation, so a served render issues no query.
- renderer: GET /offer/ fetches the tables and substitutes them at the
<#pricing_template#> marker, then renders; offer_ru.md is baked into the image
and marked is bundled from ui. GET /offer -> 301. Only /offer/ is edge-exposed.
- caddy: route /offer/ to the sidecar; drop the now-dead landing /offer/
handlers and the vite emit-offer plugin.
- offer: fill §4.3 (the chip-payment wording) and drop the in-page back link.
- landing footer: a feedback link (the offer's Telegram contact) beside the
offer link.
- docs (ARCHITECTURE, FUNCTIONAL +_ru, renderer README), CI /offer/ probe,
unit + integration + node tests.
The offer is the legal document a purchase accepts, needed before real-money
intake goes live. Convert the source PDF to an editable ui/legal/offer_ru.md and
render it to a standalone static dist/offer/index.html at build (a vite
emit-offer plugin using marked); the landing container serves it at /offer/,
with a bare /offer redirecting in. Add a small centered "Публичная оферта"
footer link on the landing (ru/en) and a CI probe asserting /offer/ serves the
page rather than silently falling through to the landing shell.
Migrate the former install-only public/sw.js to a custom (injectManifest)
service worker built from ui/src/sw.ts by vite-plugin-pwa. It precaches the
app shell + hashed assets (Workbox) so an installed web PWA cold-launches with
no network, and falls in-scope navigations back to the precached shell (the
hash router resolves the route client-side). This is the C1 prerequisite for a
usable offline mode: without it a cold offline launch cannot load the bundle.
- ui/src/sw.ts: skipWaiting + clientsClaim + cleanupOutdatedCaches +
precacheAndRoute(__WB_MANIFEST) + a NavigationRoute fallback to index.html,
deny-listing the RPC path and /_gm. The Connect stream and API POSTs are
never precached nor intercepted.
- vite.config.ts: VitePWA(injectManifest); manifest:false (we ship our own),
injectRegister:false (registration stays manual + web-only in pwa.svelte.ts),
disabled in the mock build (Playwright unperturbed); landing + polyfills
excluded from the precache.
- Removed public/sw.js; the registration path (dist/sw.js at /app/) is unchanged.
- New dev deps: vite-plugin-pwa + workbox-{core,precaching,routing}.
Docs: ARCHITECTURE + gateway/README. Offline cold-launch is contour-verified
(the mock e2e harness disables the SW).
Old Android System WebViews (the Telegram/VK in-app browser; a real device with Google
Play auto-updates the WebView, but emulators / no-Play / restricted devices stay frozen)
showed a white screen. Two causes, fixed in order:
- build.target es2022 shipped ?./?? verbatim, which the old engine cannot parse. Lowered
to es2019 so esbuild down-levels the syntax.
- The es2020+ runtime globals the bundle and its deps call (globalThis, structuredClone,
Array.at, ...) are missing on those engines. A conditional core-js loader (emitPolyfills
writes dist/polyfills.js, document.write'd by an index.html gate only when needed) covers
them; modern engines download nothing, so the bundle-size budget is untouched.
BigInt (the 64-bit FlatBuffers timestamp decode) and Proxy (Svelte 5 runes) cannot be
polyfilled, so the effective floor is Chrome 67. Below it, a permanent ES5 boot guard in
index.html shows a friendly "this device's OS or browser can't run the app" screen (with
the web-version link inside a Mini App) and a "Diagnostic information" view with a Copy
button, instead of a white screen. A reactive net raises the same screen on an uncaught
boot error that never signals window.__booted.
Board tile glyphs used container-query units (cqw, Chrome 105+) under .cell font-size:0,
so they collapsed to 0px on Chrome 74 (invisible letters); added vmin fallbacks.
The unsupported-engine telemetry beacon is a separate follow-up PR.
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.
Close out Stage 17 round 6:
- Landing page at / — one Vite build with two entries (index.html = game
SPA, landing.html = a lightweight landing reusing the theme/i18n/
aboutContent leaf modules, not the app store).
- Move the web game SPA to /app/; the Telegram Mini App stays at /telegram/
(gateway webui.Handler(stripPrefix, indexName): landing at /, SPA at /app/
+ /telegram/). Per-language "Play in Telegram" link via new
VITE_TELEGRAM_LINK_EN/_RU build vars (button hides when unset).
- Cache headers: hash-named /assets/* immutable, HTML shells no-cache (the
go:embed zero modtime emitted no validators, so the client re-downloaded
the whole bundle every launch).
- Live-stream 15s abort fix: an immediate heartbeat on open + a 10s default
interval (the first tick at 15s raced the edge idle timeout -> reconnect
storm).
PLAN/ARCHITECTURE(§13)/FUNCTIONAL(+ru)/gateway+ui+deploy READMEs updated;
round 6 closed. Tests: gateway webui/connectsrv units, ui landing unit + e2e,
full e2e (60) green.
- About screen: prominent localized title (Scrabble / Эрудит (Скрэббл)), a rules link
(en/ru Wikipedia), and the Random-game / Game-with-friends sections; copy lives in a
shared aboutContent module (the landing will reuse it). The random-game move limit
inlines the 24h auto-match clock.
- App version: Vite define __APP_VERSION__ from VITE_APP_VERSION (default 'dev'), wired as
a Docker build-arg sourced from `git describe --tags --always` in the deploy step — no
manual version bumps. The fallback keeps a plain/local build working.
New platform/telegram connector (own container, bot token only there):
- go-telegram/bot long-poll loop: /start deep-links + Mini App launch button.
- gRPC API pkg/proto/telegram/v1 (Telegram service): ValidateInitData, Notify
(renders a localized message + deep-link button), SendToUser/SendToGameChannel
(admin, wired in Stage 10). Generic methods are platform-agnostic (external_id).
- Bot API base override for Telegram's test environment; Dockerfile + compose
(VPN sidecar, no public ingress); README.
Gateway:
- initData validation relocated from the gateway into the connector; the gateway
calls ValidateInitData over gRPC (GATEWAY_CONNECTOR_ADDR), drops the bot token,
and deletes internal/auth.
- Out-of-app push: runPushPump routes events whose recipient has no live in-app
stream to connector.Notify, gated by /internal/push-target + the in-app-only
flag (race-free de-dup); HasSubscribers added to the push hub.
Backend:
- Migration 00007 accounts.notifications_in_app_only (default true) + jetgen.
- ProvisionTelegram seeds a new account's language/display name from the launch
fields; IdentityExternalID reverse lookup; /internal/push-target handler.
UI:
- Telegram Mini App launch: detect initData, apply themeParams, authTelegram,
route the deep-link start_param (g/i/f); /telegram/ guard redirects outside
Telegram. Vite relative base + telegram-web-app.js. In-app-only profile toggle;
share-to-Telegram link for a friend code. Vitest + Playwright coverage.
Wire/docs/CI: fbs Profile/UpdateProfileRequest gain notifications_in_app_only
(Go + TS); go.work uses ./platform/telegram; go-unit.yaml covers it; PLAN,
ARCHITECTURE, FUNCTIONAL (+ru), UI_DESIGN, READMEs updated.
