Collapse the two per-language Telegram bots into one unified bot and
replace language-based variant gating with explicit per-user variant
preferences.
- Telegram: one bot; drop service_language and the supported_languages
set everywhere (DB, account, auth, FlatBuffers Session wire, gateway,
connector proto). The single bot renders chat and out-of-app push in
the recipient's preferred_language; remove the game-language push
routing override (notify Intent.Language / push Event.language).
- Preferences: new accounts.variant_preferences (text[], DB default
{erudit_ru}, CHECK non-empty + subset of the three variants). Gates
the New Game picker, vs-AI and the friend invitation the player
creates, enforced server-side (HTTP 400 otherwise); an invited friend
may still accept any variant. Edited on the Settings screen; variants
are Erudit-first everywhere.
- Admin: drop the per-bot language selectors (broadcast / send-to-user)
and the feedback channel_lang column/field.
- Env/CI: collapse TELEGRAM_BOT_TOKEN_{EN,RU}, TELEGRAM_GAME_CHANNEL_ID_{EN,RU},
VITE_TELEGRAM_LINK{,_EN,_RU} and VITE_TELEGRAM_GAME_CHANNEL_NAME_{EN,RU}
to single unsuffixed names; drop GATEWAY_DEFAULT_SUPPORTED_LANGUAGES.
- Docs updated (ARCHITECTURE, FUNCTIONAL + _ru, platform/telegram, gateway,
backend, ui, UI_DESIGN, PRERELEASE).
The migration squash is deferred to a follow-up PR.
Owner review-pass rework of the landing page:
- Rename the per-language Telegram link build var
VITE_TELEGRAM_LINK_EN/_RU -> VITE_TELEGRAM_GAME_CHANNEL_NAME_EN/_RU
(it carries a channel username; the landing builds https://t.me/<name> --
the same channels the connector posts to via TELEGRAM_GAME_CHANNEL_ID_*).
- Language switcher -> a globe icon dropdown (flags + names), saved + synced
to the app prefs.
- Theme switcher -> a sun/moon icon toggle, ephemeral (follows the system
scheme, no auto, never persisted) -- galaxy-game style.
- Drop the "Play in browser" CTA (no standalone-web onboarding yet).
Docs: FUNCTIONAL(+ru), PLAN, deploy + ui READMEs.
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.
