Ilia Denisov	2c465c01d2	feat(account): VK ID web login to link a VK identity from a browser ... A browser has no signed VK Mini App launch params, so linking VK on the web uses VK ID's raw OAuth 2.1 flow (PKCE, no @vkid/sdk): the SPA redirects to VK's hosted login and returns with an authorization code, which the gateway exchanges server-side (confidential, under the VK "Web" app's protected key) for the trusted vk user id — then the existing link/merge machinery attaches or merges it. - fbs LinkVKRequest{code, device_id, code_verifier}; codec + TS bindings. - backend link.Service ConfirmVK/MergeVK/attachVK (KindVK, mirror Telegram), handleLinkVK[Merge], routes /user/link/vk[/merge], backendclient LinkVK[Merge]. - gateway internal/vkid confidential code exchange (id.vk.com/oauth2/auth); transcode link.vk.confirm/merge (registered only when configured) + config GATEWAY_VK_ID_{APP_ID,CLIENT_SECRET,REDIRECT_URL} + main wiring. - UI lib/vkid (PKCE authorize redirect + callback), Profile "Link VK" control, boot callback handling; a merge re-authorizes for a fresh code (VK codes are single-use). Web-only (a redirect strands a Mini App webview). - Deploy: VITE_VK_APP_ID + VITE_VK_ID_REDIRECT_URL build args + gateway env, ci.yaml/prod-deploy TEST_/PROD_ vars, compose/Dockerfile/.env.example/README. - Tests: vkid exchange unit (string/number user_id, id_token fallback, errors), transcode link.vk, backend ConfirmVK/MergeVK inttest, codec encodeLinkVK. - Docs: ARCHITECTURE §4, FUNCTIONAL(+ru), gateway README.	2026-07-03 17:59:33 +02:00
Ilia Denisov	65c194264c	feat(vk): embed the game as a VK Mini App ... 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.	2026-06-27 11:37:31 +02:00
Ilia Denisov	041106d623	feat(gateway): temporary IP ban (fail2ban) fed by rejections + honeypot/honeytoken ... Add a prod-only, in-memory IP ban enforced at the edge, fed by three signals: sustained rate-limiter rejections (the IP-keyed public/email/admin classes — the user class stays the backend soft-flag's concern), a honeypot decoy-path hit (the contour caddy tags decoys with X-Scrabble-Honeypot and routes them to the gateway), and a honeytoken (a planted bearer, GATEWAY_HONEYTOKEN). A banned IP is refused with 429 by the abuseGuard middleware before any work — covering the Connect edge, the live stream and the static SPA/landing the per-op limiter never gated. The ban is off by default: it keys by the real client IP the shared-NAT test contour does not expose, so a ban there would be self-inflicted; detection still logs in the contour, only the ban action is gated (GATEWAY_ABUSE_BAN_ENABLED). Rejection bans last GATEWAY_ABUSE_BAN_DURATION; tripwire/honeytoken hits are near-zero-false-positive and earn longer fixed bans. Each ban increments gateway_abuse_banned_total{reason}. Operators see and lift active bans on the admin console's Throttled page; the gateway syncs its active set to the backend every 30s (POST /api/v1/internal/bans/sync, backend/internal/banview) and applies the operator unbans the response returns. PRERELEASE phase AG. Docs baked into ARCHITECTURE / FUNCTIONAL (+ru) / both READMEs.	2026-06-21 08:54:20 +02:00
Ilia Denisov	6aeb529f13	feat(telegram): split connector into home validator + remote bot ... Move all Telegram egress off the main host. The single connector held the bot token, long-polled Telegram and answered the gateway/backend over the trusted internal network, so the whole component (including login validation) shared fate with its VPN sidecar. Split it into two binaries that share the token: - cmd/validator (home, no VPN): Mini App initData + Login Widget HMAC only, never calls the Bot API. The gateway dials it for Telegram auth, so game login is now independent of Telegram reachability. - cmd/bot (remote): Bot API long-poll + sendMessage, the only component reaching Telegram. It holds no inbound port — it dials the gateway over a new reverse mTLS bot-link (pkg/proto/botlink/v1) and executes the send commands the gateway pushes. The gateway funnels sends to the bot-link: out-of-app push is fire-and-forget (at-most-once, dropped if no bot is connected); the backend admin broadcasts reach a gateway-served relay that forwards them and awaits the bot's ack (SendToUser/SendToGameChannel contract preserved). mTLS (pkg/mtls) is the one inter-service link that leaves the trusted segment; validator<->gateway and the relay stay plaintext internal. The bot is Telegram-rate-limited. One bot now; the gateway bot registry, an owns_updates flag and per-command ids leave seams for N later. Webhook rejected (one URL per token, adds inbound + a static address). The unified test contour runs the split (the bot keeps its VPN sidecar and dials the gateway by its internal name; bot-link certs from deploy/gen-certs.sh, generated in CI). The prod wiring — the bot on a separate host (no VPN), the gateway bot-link port published, PROD_ certs with scheduled rotation, an SSH deploy of both hosts together — is the deferred final stage (PRERELEASE.md TX, Stage 18). Docs: ARCHITECTURE, PRERELEASE (phase TX), platform/telegram + gateway + backend + deploy READMEs, FUNCTIONAL(+ru), CLAUDE.md, .env.example.	2026-06-21 00:19:07 +02:00
Ilia Denisov	57c778f9b2	feat(telegram,game): single bot + per-user variant preferences ... 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.	2026-06-20 14:23:25 +02:00
Ilia Denisov	8881214213	R6(a): de-stage code, docs, READMEs; split stage6_test ... Mechanical, behaviour-preserving removal of Stage N / TODO-N / phase (RN) references from comments, doc-comments, service READMEs, the current-state docs (ARCHITECTURE, FUNCTIONAL+_ru, TESTING, UI_DESIGN), config-file comments, and the .fbs/.proto schema comments. PLAN.md / PRERELEASE.md / CLAUDE.md keep the stage history. - Rename the only stage-named identifiers: registerStage8 -> registerSocialOps, registerStage11 -> registerLinkOps (gateway transcode). - Split stage6_test.go: TestEmailLoginFlow -> email_test.go, TestGuestAutoMatchLeavesNoStats (+ provisionGuest) -> account_test.go. - Regenerated proto bindings (push.pb.go, telegram_grpc.pb.go) from the de-staged .proto comments; FB Go/TS bindings unchanged (flatc strips schema comments). go build/vet/gofmt clean across modules; integration typecheck and pnpm check green.	2026-06-10 16:56:03 +02:00
Ilia Denisov	8878711cf3	R3: gateway edge hardening — body cap, h2c sizing, rate-limit observability ... - GATEWAY_MAX_BODY_BYTES (1 MiB): connect WithReadMaxBytes + http.MaxBytesReader on the public mux; explicit http2.Server MaxConcurrentStreams/IdleTimeout and an http.Server ReadHeaderTimeout (R2 report follow-up). - gateway_rate_limited_total{class} counter, Debug per rejection, a rejection tracker drained every 30 s into a Warn summary per key and a report POST to /api/v1/internal/ratelimit/report (feeds the admin view + auto-flag). - The dead AdminPerMinute/AdminBurst policy now guards the /_gm mount (429), ahead of its Basic-Auth. - resolve() logs the cause of infra session-resolve failures at Warn (the transient unauthenticated dips from the R2 run); unknown tokens stay silent.	2026-06-10 01:58:48 +02:00
Ilia Denisov	e16076c89e	Stage 17 round 6 (#16-20): landing page, /app/ move, cache + stream fixes ... 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.	2026-06-08 13:33:05 +02:00
Ilia Denisov	c94cd3c3bf	Stage 17 (contour round 2): Grafana Live/reload, rate-limit, iOS reconnect, hint/plaque/make-move UX ... - Grafana: disable Live (GF_LIVE_MAX_CONNECTIONS=0) so its WebSocket no longer trips caddy Basic-Auth and re-prompts; admin console gains a Grafana nav link - deploy: force-recreate config-only services so reseeded Grafana dashboards / Caddyfile are actually picked up (the move-duration panel was invisible because the bind-mount went stale) - rate-limit: raise per-user budget 120/40 -> 300/80; UI skips reloading on the echo of the player's own move (fewer requests, no double-load) - iOS/Telegram reconnect: suppress the connection banner while backgrounded and for a short grace after resume; reconnect silently; wire visibilitychange + pageshow/pagehide + Telegram activated/deactivated (Bot API 8.0) - hint button disabled when 0 hints remain; nudge button shows a disabled state on your own turn - players plaque: invert so the active seat pops (accent chip, raised) and others recede - make-move UX: a direct ✅ commit button (no hold/popover); the Shuffle tab becomes ↩️ Reset while tiles are pending	2026-06-06 12:33:52 +02:00
Ilia Denisov	e9f836db87	Stage 15: dual Telegram bots & language-gated variants ... Service-agnostic refinement of the owner's idea: the sign-in service returns a set of supported game languages with the user identity, and the lobby gates the New Game variant choice by it (en -> English; ru -> Russian + Эрудит). - Connector hosts two bots in one container (one per service language, each its own token + game channel; the same telegram_id spans both). ValidateInitData tries each token and returns the validating bot's service_language + supported_languages. Per-language config (TELEGRAM_BOT_TOKEN_EN/_RU, channels). - supported_languages rides the Session (fbs, session-scoped, not persisted); the UI offers only the matching variants on New Game — gating only the START of a new game (auto-match + friend invite), not accept/open/play; backend does not enforce. - service_language persisted (accounts.service_language, migration 00010, written every login, last-login-wins) and routes the user-facing Notify push back through the right bot (push-target coalesces with preferred_language). - Admin SendToUser/SendToGameChannel gain an operator-chosen language selector in the console (unrelated to ValidateInitData). - Non-Telegram logins carry the gateway default set (GATEWAY_DEFAULT_SUPPORTED_LANGUAGES, all variants). Wire (committed regen): ValidateInitDataResponse +service_language +supported_languages; Session +supported_languages; SendToUser/SendToGameChannel +language. Docs (ARCHITECTURE/FUNCTIONAL/_ru/READMEs) + PLAN updated; stage marked done.	2026-06-05 09:35:53 +02:00
Ilia Denisov	dcd8de8b00	Stage 12: observability & performance (OTel/OTLP, domain metrics, guest GC) ... - pkg/telemetry: shared OTel provider bootstrap (none/stdout/otlp + W3C propagators + Go runtime metrics); backend/internal/telemetry becomes a thin facade keeping its gin middleware. - Telemetry parity: gateway and the Telegram connector gain telemetry runtimes and config (GATEWAY_/TELEGRAM_ SERVICE_NAME + OTEL_*); otelgrpc instruments the backend push server, the gateway's backend+connector clients and the connector server. Default exporter stays none (collector/dashboards are Stage 14). - Operational metrics (variant attribute on game-scoped ones): game_replay_duration, game_move_validate_duration, games_started_total, games_abandoned_total, game_cache_active, chat_messages_total{kind}, gateway edge_request_duration. Wired via the SetMetrics setter pattern (default no-op meter). - TODO-3: account.GuestReaper deletes guests with no game seat past BACKEND_GUEST_RETENTION (default 30d, swept every BACKEND_GUEST_REAP_INTERVAL). - Tests: pkg/telemetry exporter selection; game/social/edge metric recording via a manual reader; config (otlp accepted, guest knobs); inttest guest reaper. - Docs: PLAN.md re-scopes Stage 12 and adds Stage 13 (alphabet-on-wire) + Stage 14 (CI/deploy) with the agreed dictionary-versioning resolution; ARCHITECTURE 11/13, TESTING, the three READMEs and FUNCTIONAL(+ru) updated.	2026-06-04 14:22:15 +02:00
developer	3a640a17a4	Stage 10: admin console & dictionary ops (complaint review, hot-reload, broadcasts) (#11)	2026-06-04 07:27:49 +00:00
Ilia Denisov	cf66ed7e26	Stage 9: Telegram integration (connector side-service, Mini App, out-of-app push) ... 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.	2026-06-04 07:10:21 +02:00
Ilia Denisov	408da3f201	Stage 6: gateway edge (Connect/FlatBuffers over h2c, platform/email/guest auth, sessions, rate-limit, admin passthrough, live push bridge) ... New public ingress and the first network edge. Framework + a vertical slice of operations end-to-end; remaining ops reuse the same transcode pattern in Stage 7. Contracts (new module scrabble/pkg): - push.proto (backend->gateway gRPC server-stream) + scrabble.fbs (FlatBuffers edge payloads), committed generated Go; buf/flatc Makefiles (dev-time codegen). Backend: - REST handlers on the /api/v1 groups: internal session endpoints (telegram/guest/email login -> mint, resolve, revoke) and the user slice (profile, submit_play, state, lobby enqueue/poll, chat). - internal/notify in-process Publisher hub + internal/pushgrpc gRPC server (BACKEND_GRPC_ADDR) streaming your_turn/opponent_moved/chat/nudge/match_found; emission in game.commit, social, matchmaker. - migration 00005 accounts.is_guest; guests are durable rows excluded from stats; ProvisionGuest; email-as-login (RequestLoginCode/LoginWithCode). Gateway (new module scrabble/gateway): - Connect Gateway service over h2c (Execute + Subscribe), FlatBuffers<->JSON transcode registry, Telegram initData HMAC validator (seam), session cache, token-bucket rate limiter (3 classes), push fan-out hub, backend REST + push gRPC client, admin Basic-Auth reverse proxy. go.work: use ./pkg, ./gateway + replace scrabble/pkg. CI: gateway/**, pkg/** path filters; unit build/vet/test span all three modules. Docs (PLAN, ARCHITECTURE, FUNCTIONAL+ru, TESTING, READMEs) updated; gateway/pkg unit tests + guest/email-login integration tests.	2026-06-02 22:38:24 +02:00
