Ilia Denisov	e71e40eef5	feat(telegram): promo bot + channel-chat moderation gate ... Add a second standalone promo bot to the bot container (answers /start with a localized message + a URL button into the main bot's Mini App) and gate write access in a channel's linked discussion chat: grant on join when the Telegram user is registered and neither admin-suspended nor holding a new chat_muted role, and revoke/grant on the matching moderation change for a member currently in the chat. Eligibility (registered AND NOT suspended AND NOT chat_muted; the game suspension dominates) is resolved once in the backend and reached two ways: the bot's join-time unary ResolveChatEligibility over the existing mTLS bot-link, and a backend chat_access_changed event -> gateway -> ChatGate command (idempotent; a temporary-block-expiry sweeper may over-emit). The bot guards the block/unblock path with getChatMember, since bots cannot list members. A web_app button cannot open another bot's Mini App (it signs initData with the sending bot's token), so the promo button is a t.me ?startapp URL reusing the UI's VITE_TELEGRAM_LINK. The bot must be a chat admin with the restrict-members right and chat_member in its allowed updates. No schema change: chat_muted reuses the data-driven account_roles table.	2026-06-21 14:46:51 +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).

Ilia Denisov	95f5703372	fix(engine): make .seed_version marker authoritative (no boot refusal) ... The seed-drift guard shipped as refuse-boot: the backend exited when BACKEND_DICT_VERSION disagreed with the flat dir's recorded .seed_version. On the test contour that turned a harmless-in-intent action — bumping the TEST_DICT_VERSION variable to the active release (v1.2.1) on a volume seeded as v1.0.0 — into a crash loop, because DICT_VERSION is the *seed* of a fresh volume, not the active version (which the admin console drives). Make the marker authoritative instead: OpenWithVersions resolves the flat dir's version from .seed_version when present and ignores bootVersion on an already-seeded volume; bootVersion only seeds a fresh volume's marker. So a bumped build seed on a live volume is a no-op (it can't relabel live bytes and can't void games pinned to the prior label), and it correctly seeds the next fresh volume. The subdirectory scan now skips the resolved seed, so a version also present as a subdir (e.g. v1.2.1 uploaded via the console while the build seed is bumped to v1.2.1) is still loaded rather than shadowed by the flat bytes. Tests: marker-wins over a bumped boot version; a bumped boot keeps the matching subdir resident (the live-contour case). Docs updated (ARCHITECTURE §5, READMEs, compose/.env, PRERELEASE DV) from "refuses to boot" to "marker wins / ignored". Verified locally against v1.2.1: gofmt, build, vet, unit, integration green.	2026-06-20 20:06:57 +02:00
Ilia Denisov	a5db10c46e	feat(engine,deploy): seed-drift guard + track current dictionary release ... The dictionary release moved to v1.2.1 while DICT_VERSION stayed pinned at v1.0.0 in CI and the image/compose seed defaults. Two problems: 1. CI validated against a stale dictionary. 2. The contour seed could be bumped on a live volume, which silently relabels the already-seeded bytes — voiding games pinned to the prior label and serving the wrong dictionary for new ones. The flat DAWGs carry no embedded version, so this drift was undetectable. Changes: - Seed-drift guard: OpenWithVersions records the flat dir's version in a .seed_version marker on first boot and refuses to start when a later BACKEND_DICT_VERSION disagrees. DICT_VERSION is now the seed for a *fresh* volume only; a live contour migrates through the admin console (old versions stay resident, in-progress games keep replaying). - Track the current release: CI's DICT_VERSION centralised to one workflow-level env (v1.2.1); image/compose/.env seed defaults bumped to v1.2.1. The deploy job keeps reading the per-contour vars.TEST_DICT_VERSION. - Docs: ARCHITECTURE §5 (decision record), backend/deploy READMEs, PRERELEASE tracker (DV row). Verified locally against the v1.2.1 artifact: gofmt, build, vet, unit and integration (-tags=integration) all green.	2026-06-20 19:26:32 +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	caefc8f579	feat(game): official first-move tile draw + admin step-by-step replay ... Decide who moves first by the official rule: each seated player draws one tile, the one closest to "A" leads (a blank beats every letter), ties re-drawing until a single leader remains. Each draw uses honest per-draw crypto/rand entropy (not the deterministic bag seed), so the recorded draw — not a seed — is the only account of the outcome. The leader takes seat 0, so the engine and journal replay are unchanged. The draw is recorded with the game (game_setup_draws, migration 00013) for future tournaments, designed as a discrete "player N draws a tile" step. Friend/AI games draw at creation. Auto-match draws when the game opens, against a synthetic uuid.Nil opponent whose draw rows (NULL account_id) are back-filled to the real opponent on join — so the opener's seat is fixed up front and the existing open-game pre-move is preserved with no reseating. Admin /_gm/games/:id gains the recorded draw list and a simple step-by-step board replay (game.ReplayTimeline + a vanilla-JS stepper): a board with A-O/1-15 headers and highlighted premium squares, placed letters with their tile value as a subscript, rack panels around the board (seat 0 top, 1 bottom, 2 left, 3 right) with the current player highlighted, and a per-move log with the tiles drawn and the bag remainder.

Ilia Denisov	64be0572b3	fix(social): robot blocks ... Blocking an auto-match opponent who is secretly a pooled robot is recorded instead in a separate `robot_blocks` table. Now blocking behaves the same in that game (struck name, hidden composer) and lists the blocked opponent under the name you saw, but is recorded only against that game — the disguise holds, the shared robot is never globally blocked, and the matchmaker keeps pairing you with robots (so you can never block yourself out of opponents). - the shared robot account is never put in `blocks` - the matchmaker keeps it free and it is not blocked under its other per-game names - the blocked list and the in-game card still show it by joining that table; an unblock deletes the row	2026-06-18 13:12:19 +02:00
Ilia Denisov	81b9e1529e	feat(social): asymmetric per-user block, in-game block control, admin lists ... Make a per-user block one-directional and non-destructive: the blocker stops receiving everything from the blocked user (chat, nudge, friend requests, invitations) and the matchmaker never pairs them, while the blocked user notices nothing — their sends still persist by the normal rules but are never delivered or surfaced (born-read). A block no longer deletes the friendship (an unblock cleanly restores it) and instant-reads any unread the blocked user had left for the blocker. - backend: a directional blockExists guard across chat/nudge/friends/invitations (store-but-hide for the blocked->blocker direction, refuse blocker->blocked); the matchmaker excludes a block-related pair (both directions) from auto-match; user_blocked/user_unblocked notifications to the blocker only (in-app only). - ui: the opponent score card gains a block ✖️ control mirroring add-friend (red "Block?" confirm, mutual-hide while confirming, struck name, hidden chat composer when blocked); optimistic apply + event confirm + rollback for both. - admin: the user card gains cross-linked blocks / blocked-by / friends lists. - docs: FUNCTIONAL(+ru), ARCHITECTURE §10 + decision record, UI_DESIGN, PRERELEASE.	2026-06-18 11:50:34 +02:00
Ilia Denisov	c3b3cafcdd	feat(observability): add the Scrabble — Messages Grafana dashboard ... Visualises the chat read-receipt metrics added with the read-receipt feature (the dashboard was deferred there per the owner): posted rate by kind, the unread backlog (chat_unread_messages gauge), and the publish-to-read latency (chat_read_duration — average by kind plus overall p50/p95). Mirrors the game-domain dashboard's structure; the file provider auto-discovers it.	2026-06-17 12:00:58 +02:00
Ilia Denisov	aaac816dc2	feat(chat): unread read-receipts with lobby/game dot and history-open ack ... Persist per-message read state as a chat_messages.unread_seats bitmask (migration 00008): a text message seeds every recipient seat's bit, a nudge only the awaited seat's. A seat's bit clears when the player opens the move history or chat (POST /games/:id/chat/read, sent only when something is unread), and a nudge additionally clears when its recipient answers by moving (a wired game NudgeClearer, dependency-inverted so game keeps off social). UI shows a per-viewer unread dot in the lobby (next to the opponent) and the game score bar — the unread_chat game-view flag seeds it from authoritative REST views, live chat/nudge events raise it. Opening the move history counts as reading (even without entering chat): the 💬 fade-blinks twice and the client acks. Admin Messages gains an unread-only filter, a read/unread column, and a per-message card with the per-seat read breakdown. Observability: chat_read_duration histogram + chat_unread_messages gauge + social tracing.	2026-06-17 11:12:38 +02:00
Ilia Denisov	63ab85a5e5	feat(lobby): cap simultaneous quick games at 10 ... Limit a player to 10 active quick games (auto-match + AI); friend games created by invitation are not counted. At the cap the backend refuses both new-game entry points — quick enqueue and invitation creation — with 409 game_limit_reached, while accepting an incoming invitation stays allowed, so friend games are capped from the other end. The lobby disables "New Game" and shows a low-emphasis notice, driven by a new at_game_limit flag on games.list (no per-event payload: a turn change does not move the count, and the lobby already re-fetches games.list on entry and every game event). - game.MaxActiveQuickGames + Store/Service.CountActiveQuickGames (active/open seats, no game_invitations row; hidden games still count -> dedicated count) - Server.ensureUnderGameLimit gating handleEnqueue + handleCreateInvitation; game.ErrGameLimitReached -> 409 game_limit_reached - FB GameList.at_game_limit (regenerated Go + TS) through the gateway transcode and UI codec; gameListDTO + lobbycache snapshot + Lobby.svelte + i18n - tests: integration count rule + HTTP gate + accept bypass; server error map; gateway transcode round-trip; UI codec + lobbycache unit; e2e gamelimit - docs: PRERELEASE (GL), FUNCTIONAL(+ru), ARCHITECTURE 8, UI_DESIGN, backend README	2026-06-16 22:51:18 +02:00
Ilia Denisov	cb4a31a860	feat(ads): client banner rotation, fade UX & live toggle (PR2) ... Consume the server-driven banner block (PR1) in the UI and retire the gate. - banner.ts: createScheduler — a smooth weighted round-robin over campaigns (each appears its weight share per cycle, evenly interleaved) with round-robin over a campaign's messages; the rotator drives fade-in -> hold/scroll -> fade-out -> gap -> fade-in, a lone message stays put, reduce-motion swaps instantly without scroll. - model.ts/codec.ts: Profile.banner (Banner/BannerCampaign/BannerTimings) decoded from the fbs block. - Screen.svelte: drop the compile-time SHOW_AD_BANNER; render AdBanner from app.profile.banner (campaigns + timings + reduceMotion). - AdBanner.svelte: opacity-driven fades + scroll host; the rotator is recreated when the campaigns/timings change (a `banner` notify re-fetch swaps them in place). - app.svelte.ts: on the `notify` `banner` sub-kind, refreshProfile() so the banner shows/hides in place. - tests: scheduler distribution + round-robin, the fade sequence, single-message, reduce-motion, stop(); codec banner decode. UI_DESIGN.md + trackers updated.	2026-06-15 23:25:27 +02:00
Ilia Denisov	0946a3f66c	feat(ads): server-driven ad-banner backend, wire & admin console (PR1) ... Turn the gated-off mock banner into a real advertising subsystem (backend + admin half; the UI rotation lands in PR2). - internal/ads: campaigns (percent weight + validity window; a perpetual, undeletable default that fills the remainder up to 100%), 1..N bilingual messages (en+ru), global display timings; ActiveSet computes the window-filtered, default-remainder, GCD-reduced, language-resolved rotation feed. Smooth-weighted-round-robin math is unit-tested. - migration 00006 (+ jetgen): ad_campaigns / ad_messages / ad_settings, seeded default campaign + house message + default timings. - eligibility = !paid_account && hint_balance==0 && !no_banner role (new role; guests qualify). The resolved feed rides the profile.get response (no new RPC, works for guests, nothing distinct to filter); language by service_language. - live update: a notify `banner` sub-kind (re-poll signal) published when an operator grants hints or grants/revokes no_banner, so the client shows/hides in place. - admin console /_gm/banners (+ /_gm/banner-settings): campaign + message CRUD with reorder, default protection, clamped timings. - wire: fbs BannerInfo/BannerCampaign on Profile; gateway transcode forwards it. - docs: ARCHITECTURE §10, FUNCTIONAL (+ _ru), backend README, PRERELEASE tracker (incl. the deferred app.load aggregator note).	2026-06-15 23:00:19 +02:00
Ilia Denisov	3bceafbc12	feat(robot): occasional off-strategy deviation, strict in the endgame ... The robot followed its per-game playToWin/lose intent on every move, which made the outcome too predictable. It now flips that intent for a single move on ~20% of opening/midgame turns (a winning robot eases off, a losing one surges ahead), so the chosen strategy may not pan out — which favours the human. The chance tapers linearly to 0 over the last 14 tiles in the bag and is 0 once the bag is empty, so the endgame follows the chosen strategy strictly. The decision is deterministic from the seed (mix(seed,"deviate",moveCount)) and applies to both robot paths via the shared selectMove; the per-game play-to-win intent the admin card shows is unchanged. Adds deviateProb/deviates helpers and unit tests (taper bounds + monotonicity, never-in-endgame, determinism, ~20% distribution); bakes the behaviour into ARCHITECTURE §7, FUNCTIONAL (+_ru), backend/README, PRERELEASE and PLAN Stage 5.	2026-06-15 21:37:23 +02:00
Ilia Denisov	d2a9441287	feat: AI-game refinements (GCG, your_turn, admin, metrics) ... Follow-ups on the honest-AI game, same PR: - GCG export labels the robot seat "AI" instead of its pool name (ExportGCG overrides via accounts.IsRobot); the in-app 🤖 is unchanged. - vs_ai games emit no your_turn (the robot replies instantly, so it would be redundant); opponent_moved still advances the UI. - Admin console shows the AI flag: a 🤖 column in /games and an "AI game" line on the game card (GameRow/GameDetailView gain VsAI). - games_started_total / games_abandoned_total gain a vs_ai attribute; the Grafana Game-domain dashboard splits started/abandoned into human and AI panels. Tests: metrics unit (vs_ai split); integration (no your_turn, GCG "AI").	2026-06-15 20:49:49 +02:00
Ilia Denisov	aa765a0c06	feat: honest AI opponent in quick game ... New Game's quick game gains an explicit opponent selector — 🤖 AI (default) or 👤 Random player. AI starts a game seated with a pooled robot that joins and moves at once: no per-move timeout (a 7-day inactivity loss reusing the turn-timeout sweeper), chat/nudge disabled, no statistics, the opponent shown as 🤖 everywhere. The random path (disguised robot) is unchanged. Driven by one game flag (games.vs_ai), set only on AI-started games so the disguised path is never revealed; Matchmaker.StartVsAI seats the robot directly (no open pool); the robot replies event-driven via the game service's after-commit/after-create hook. Wire: vs_ai on EnqueueRequest + GameView.	2026-06-15 20:14:24 +02:00
Ilia Denisov	d1ba666495	feat(admin): manual account blocking (suspensions) ... Operator-driven hard block, the counterpart to the soft high-rate flag: permanent or until a date, with an optional reason chosen from an editable en+ru picklist (snapshotted onto the block). A block forfeits the player's active games (opponent wins, as a resignation) and cancels their open matchmaking games. A backend gate refuses a blocked account on every /api/v1/user/* route except the block-status probe with 403 account_blocked, which threads through the gateway as the Execute result_code; the UI surfaces it as a terminal blocked screen and stops all push/poll. Temporary blocks self-expire; the operator can unblock at any time (lost games stay lost). Sessions are not revoked, so the blocked client can still reach the exempt block-status endpoint. Backend: migration 00003 (account_suspensions + suspension_reasons) + jet regen; account suspension store; game.ForfeitAllForAccount; requireNotSuspended gate + block-status endpoint; admin console block/unblock + Reasons CRUD. Wire: fbs BlockStatus + account.block_status gateway op. UI: blocked screen, app state, transport/codec, i18n. Docs: ARCHITECTURE, FUNCTIONAL(+ru), PRERELEASE (AB).	2026-06-14 21:55:59 +02:00
Ilia Denisov	222eaf730f	feat(game): void unreplayable games as a draw instead of erroring ... A committed move that becomes illegal under a tightened rule (the single-word connectivity fix) makes engine replay fail, which left such games unopenable — an empty screen and an 'illegal play' error. Now the first open closes the game gracefully as a draw (engine.EndAborted -> end_reason 'aborted', no winner), preserves the journal, and surfaces an impersonal organizer note at the end of the move history and in the GCG export. - engine: EndAborted + Abort() (draw, no rack adjustment; winner -1). - service: replay aborts on ErrIllegalPlay; liveGame persists the void once (lazy, on open); GameState re-reads for the settled view. - store: VoidGame finishes the game and stamps a draw without a journal row. - migration 00002: allow end_reason 'aborted'. - ui: organizer note under the history grid; i18n en/ru. - docs: ARCHITECTURE 6/9.1, FUNCTIONAL(+ru), PRERELEASE MW3.	2026-06-14 16:57:27 +02:00
Ilia Denisov	ff87a3bf62	fix(engine): single-word rule connects along the play line ... Bumps the engine to scrabble-solver v1.1.1, where a single-word-per-turn play must form its word along its own line through an existing tile: a multi-tile play that touches the board only perpendicular to itself (the contour РЮМ/КЕД/ОР cases) no longer connects. For a single tile that abuts the board on both axes the engine now plays the higher-scoring legal orientation instead of the geometrically longer one (playDirection), so a real word is never rejected in favour of a non-word. Reworks the single-word solver/engine tests for the corrected rule (no longer a superset of standard play) and updates ARCHITECTURE/FUNCTIONAL/PRERELEASE.	2026-06-14 14:49:16 +02:00
Ilia Denisov	0f3671f42d	feat(admin): online dictionary update — upload archive, preview word diff, install & activate ... Replace the dictionary hot-reload with an online update flow in the GM console (/_gm/dictionary): the operator uploads scrabble-dawg-vX.Y.Z.tar.gz, previews the per-variant words added/removed against the active dictionary, and confirms to install + activate it. Versions are immutable; in-progress games keep their pinned version while new games use the new one. - engine: DiffWords (enumerate both DAWGs, decode only the differences), OpenFinder, Registry.Finder, DictFiles; OpenWithVersions skips the .staging area. - dictadmin: hardened release-archive validation + extraction (path-traversal, symlink, oversize, entry-count rejection) and staging -> install (atomic rename). - game: active dictionary version persisted in the dictionary_state singleton (single source of truth, restored on boot), concurrency-safe accessor. - storage: BACKEND_DICT_DIR is a named volume seeded from the image (nonroot-owned), so uploaded versions persist across redeploys; the build's DICT_VERSION labels the seed and equals the resident tag (BACKEND_DICT_VERSION). - docs: ARCHITECTURE §5, FUNCTIONAL (+ru), backend README, TESTING, PRERELEASE. Tests: engine + dictadmin unit; integration upload->preview->install->activate-> restart->pin->immutability->CSRF.	2026-06-13 23:29:06 +02:00
Ilia Denisov	a4e6727c70	feat(ui): merge Exchange/Pass into one action; drop dead Tournaments tab ... Lobby: remove the inert 🏆 Tournaments tab (it only raised a 'coming soon' toast); the lobby is back to three tabs, matching docs/FUNCTIONAL.md. Game: fold the separate 🥺 Skip (pass) tab into the 🔄 tab, now Exchange/Pass. Its dialog passes when no tile is selected (button 'Pass without exchanging') and exchanges when tiles are ('Exchange N'). The tab is no longer gated on an empty bag (pass must stay reachable in the endgame); inside the dialog tile selection is disabled while the bag is below a full rack (bagLen >= RACK_SIZE). The merge is UI-only. A pass is NOT an exchange of zero tiles: the rules allow an exchange only with a full rack left in the bag and forbid a zero-tile swap, while a pass is always legal; GCG (Poslfit) writes a pass as a bare '-' and an exchange as '-TILES'. Pass and exchange stay distinct end-to-end (wire, engine, history/GCG); the dialog dispatches the existing gateway.pass / gateway.exchange. No backend/wire/history/GCG change. Docs: docs/UI_DESIGN.md, docs/FUNCTIONAL.md (+_ru), PRERELEASE.md. Tests: ui/e2e/game.spec.ts.	2026-06-13 16:41:55 +02:00
Ilia Denisov	c305363ccd	feat(lobby): enter the game immediately and wait for the opponent inside it ... Quick auto-match no longer waits on a separate screen: Enqueue opens a real game seating the caller with an empty opponent seat (new game status 'open') and the player enters it at once. A second human searching the same variant+rule joins that open game; otherwise a background reaper seats a robot after a 90s + random 0-90s wait, pushing a new in-app opponent_joined event that fills the opponent card and re-enables resign and chat in place. Matchmaking state is now the open games in the database (the in-memory pool, lobby.poll and lobby.cancel are gone), serialised by a per-bucket advisory lock. While a game is open the starter may move on their turn, but resign, chat and nudge are refused; the lobby and opponent card show "searching for opponent". Schema edited in the baseline (no prod data): 'open' status, nullable game_players.account_id for the empty seat, and a games.open_deadline_at stamp; jet code regenerated.	2026-06-12 16:00:22 +02:00
Ilia Denisov	74455c7b12	feat: "multiple words per turn" rule for Russian games ... Add a per-game rule chosen on New Game for Russian variants (default off = the single-word rule; on = standard Scrabble). Off, only the main word along the play direction is validated and scored; perpendicular cross-words are ignored, including in robot move generation. The rule rides every create and enqueue request and joins the matchmaking key, so games and auto-match stay one uniform path; "Russian-only" is a UI affordance (English always sends standard and shows no toggle). - Engine: consume scrabble-solver v1.1.0's PlayOptions{IgnoreCrossWords}, threaded through engine.Options.MultipleWordsPerTurn -> playOpts() into validate, score and generate. - Backend: thread the flag through game CreateParams/Game + store (games column), lobby InvitationSettings + invitation row, and the matchmaker queue key (variant + rule); persisted, so a rebuilt-from-journal game keeps it. Baseline migration gains multiple_words_per_turn (DB not versioned); jet regenerated. - Edge: multiple_words_per_turn added to the EnqueueRequest / CreateInvitationRequest FlatBuffers tables (Go + TS regenerated) and threaded through the gateway. - UI: a "Multiple words per turn" toggle on New Game, shown for Russian variants only (auto-match and friend invite), default off; English silently sends standard. - Tests: backend engine/matchmaker; UI unit (gating) + Playwright e2e (solver corner-case + GCG fixtures ship in v1.1.0).

Replace Menu.svelte (hamburger) everywhere with tab-bar navigation: - Settings hub (SettingsHub) from the lobby ⚙️ tab: Settings/Profile/ Friends/About as in-place tabs, back → lobby; the lobby ⚙️ badge counts incoming friend requests (invitations keep their own lobby section). - Comms hub (CommsHub) from the move-history 💬: Chat/Dictionary tabs, back → game; Dictionary only while the game is active. - Game menu items relocate into the open history: 🏁 leave / 📤 export in the header, 🤝 add-friend per opponent card, 💬 comms; unread chat is badged on the score bar + the 💬. - TapConfirm (tap → fading ✅ → tap) replaces the Skip/Hint press-and-hold popovers and drives the add-friend confirm. - Fix the move-history "jump": the slid board is inert and the stage can't scroll, so a swipe up genuinely closes the history. Remove Menu.svelte + HoldConfirm.svelte. Docs: UI_DESIGN, FUNCTIONAL(+ru), PRERELEASE. UI check/unit/build/bundle/e2e (Chromium+WebKit) all green.	2026-06-11 14:13:54 +02:00
Ilia Denisov	2a48df9b83	R7: trip report + docs/tracker bake-back; mark R7 done ... - loadtest/REPORT-R7.md: the final stress-run report — method, the 500-player resource profile, the agreed tuning, the validation (transport_error 2.49% -> 0.72% at 3 gateway cores; the burst run showing connection-bound behavior), and the prod-sizing recommendation for Stage 18. - loadtest/README.md: per-player transports, --cpus capping, docker_stats (was cAdvisor), the absolute BACKEND_DICT_DIR for ./loadtest/... , and report links. - docs/TESTING.md + docs/ARCHITECTURE.md: observability now uses the otelcol docker_stats receiver (cAdvisor removed); links to both trip reports. - CLAUDE.md: repo-layout line reflects docker_stats + per-service limits. - PRERELEASE.md: R7 marked done in the tracker + heading; a Refinements entry recording the decisions, findings, applied tuning and validation. This is the final pre-release hardening phase; Stage 18 (prod cutover) is next.	2026-06-11 11:18:57 +02:00

Ilia Denisov	d4ef951db9	R5: bundle slimming — retarget the budget to the app, no code slimming ... Analysed the real dist (gzip + sourcemap attribution): the bundle is already minified + tree-shaken and dominated by the Connect/FlatBuffers transport runtime + generated bindings + the Svelte runtime (~2/3 of main), so no in-scope code slimming is warranted. Lazy-loading was rejected (bundle-size.mjs sums every chunk -> zero total-size win, plus +N gateway fetches of latency); i18n lazy-load and chunk-collapsing likewise (caching/HTTP2). Instead bundle-size.mjs now measures per HTML entry with three independent gates (app entry <=100 KB, Svelte+i18n shared <=30 KB, landing-own <=5 KB): the app's real payload is its entry chunk + the shared chunk (~97 KB), never landing.js. Same CLI + exit-code contract, CI step unchanged. Fixed the stale ~82 KB figure in the script and ui/README.md. No app code change.	2026-06-10 15:11:45 +02:00
Ilia Denisov	41a642ef97	R4: push enrichment — events carry a state delta, kill the last poll ... Enrich the in-app live stream into a delta channel so the UI renders a move from the event without a follow-up game.state, and make the matchmaking poll a stream-down fallback. - pkg/fbs: trailing fields on opponent_moved (move+game+bag_len), your_turn (move_count), match_found (state), game_over (game), notify (account/invitation/state), MoveResult (rack+bag_len); regenerate Go + TS. - backend: notify owns the FB encoding (encode.go + payload.go input structs); game/lobby/social map their domain types in. emitMove builds the move delta; game.Service.InitialState feeds match_found/game_started the recipient's initial StateView; friends/invitations notify carry their account/invitation. The move-commit response (submit_play/pass/exchange/resign) returns the actor's refilled rack + bag size. - gateway: MoveResult transcode carries rack+bag_len. - ui: pure lib/gamedelta.ts reducer advances the per-game cache keyed on move_count (idempotent + gap-safe); app.svelte seeds the cache on match_found/game_started; Game.svelte applies the delta (commit/pass/exchange/resign drop their load()); NewGame polls only while app.streamAlive is false. - docs: ARCHITECTURE §10, FUNCTIONAL(+ru), backend/gateway/ui READMEs; PRERELEASE R4 marked done + Refinements.	2026-06-10 08:01:50 +02:00
Ilia Denisov	7e75c32d07	R3: dashboards, docs and tracker bake-back ... - Edge/UX dashboard: aggregate request-rate vs rejection-rate panel (gateway_rate_limited_total by class; no per-user labels). - ARCHITECTURE §2/§11/§12/§13: body cap + explicit h2c sizing, the rate-limit observability pipeline and auto-flag policy, the admin-limiter note (and the caddy-path gap), the landing container topology; fixed the stale 120/min per-user figure. - FUNCTIONAL (+_ru): the Throttled view and the reversible high-rate flag. - gateway/backend/deploy READMEs, TESTING.md, root CLAUDE.md updated. - PRERELEASE.md: R3 interview decisions + implementation refinements logged; tracker R3 -> done (this PR implements it; CI gates the merge).	2026-06-10 05:12:30 +02:00
Ilia Denisov	a2265a122e	R2: early-pass trip report + mark R2 done ... Ran the moderate early pass (50/200/500, 10 min/step) against the contour: ramped clean to 500 players, 1.2 M edge calls, 48 870 plays, 2 798 games finished, no crash/deadlock; cleanup removed all 11 000 seeded accounts. The per-user limiter held under the gateway-hammer (99.97 % rejected, p99 2 ms). Top finding: ~14 % transport_error on game.state at 500 players under CPU saturation (backend/gateway/Postgres each ~1 core), amplified by the harness's single shared http2.Transport (the harness itself peaked at 86 % of a core on the same host). Observability finding: cAdvisor yields only the root cgroup on the contour host (separate XFS /var/lib/docker); per-container metrics captured via docker stats; R7 should adopt the otelcol docker_stats receiver. Full report in loadtest/REPORT-R2.md; PRERELEASE refinements logged; R2 marked done.	2026-06-10 00:47:16 +02:00
Ilia Denisov	8bfc44aad0	R1: mark done in PRERELEASE.md (post-merge close-out) ... scrabble-game #31 + scrabble-dictionary #2 merged, v1.0.1 cut, contour DB wiped and re-migrated to the baseline (verified).	2026-06-09 16:11:03 +02:00
Ilia Denisov	26aa154547	R1: schema & naming reset — squash migrations, rename variants ... Squash the 12 goose migrations into one 00001_baseline.sql (there is no prod data; verified schema-identical to the chain via a pg_dump diff + the green integration suite) and rename the game-variant labels english/russian_scrabble/erudit -> scrabble_en/scrabble_ru/erudit_ru across the backend, the FlatBuffers wire values and the UI. dawg filenames and the Go enum identifiers are unchanged; the i18n display keys are kept. Adds PRERELEASE.md (the R1-R7 pre-release tracker), linked from CLAUDE.md. Contour DB wipe and the scrabble-dictionary tidy are follow-ups.	2026-06-09 12:09:50 +02:00
