Ilia Denisov	f9acea1d9a	fix(game): clear nudges on game completion ... Nudge badges lingered in the lobby on games that ended by turn-timeout, resignation or forfeit: those paths commit the finish directly, bypassing the move path's per-mover NudgeClearer, so the awaited seat's nudge was never marked read. A finished game's nudges are stale, so clear them all. Add a wired NudgeExpirer (social.ExpireNudges) called from the shared commit finish block — covering every completion path — and from the voidGame recovery path. It clears every seat's nudge bits for the game and leaves chat messages unread; unlike ClearNudges it records no publish-to-read latency, since a completion is an expiry, not a read. An integration test reproduces the timeout case (nudge cleared, chat kept). Docs: ARCHITECTURE §9.1, FUNCTIONAL (+_ru), backend/README.	2026-06-30 22:51:54 +02:00
Ilia Denisov	ecb21bd218	perf(backend): cut evaluate's DB round-trips; load the game in one query ... EvaluatePlay (the hottest gameplay call, fired on every tile placement) now uses the warm live-game cache directly: an active game stays cached (mutated in place across moves, evicted only on finish), so the cached engine game and its immutable seat list answer the membership check and the score with no DB read. The cold path (eviction / first load) still loads and validates via the store. The seat list is cached alongside the engine game for the membership fast path. GetGame also folds its two round-trips (game, then seats) into one LEFT JOIN, preserving the contract (same Game, a seatless game still returns empty seats, seat order kept) — one round-trip for every remaining caller. Measured at 500 players: evaluate p99 halves (200 -> 100 ms) and the per-op query count drops. It does NOT cut postgres CPU — that is write-bound (per-move CommitMove plus draft upserts and journal replays), the cheap indexed GetGame reads were never its bottleneck, and postgres runs with headroom (~1.5 of 2 cores). So this is a latency / query-volume optimization, not a DB-CPU one. Regression cover: a non-player evaluate against a warm game asserts the cached-seat membership path; the integration suite exercises GetGame's join across every game op.	2026-06-21 20:47:13 +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	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	9d52885a6e	fix(matchmaking): re-enqueue opens a new game, not the caller's own ... A second "random opponent" enqueue with the same variant and per-turn rule, while the caller's first game was still open (awaiting an opponent), returned that same open game, so a player could never start a fresh random game while one was still searching. Drop the own-open short-circuit (step 1) in store.OpenOrJoin: a re-enqueue now joins another player's open game or opens a fresh one. Accumulation stays bounded by MaxActiveQuickGames, which counts open games. Update the matchmaker/service/store doc comments and ARCHITECTURE.md, and flip the pinning test to assert the new behavior.	2026-06-18 10:18:44 +02:00
developer	8793bd34f2	feat(stats): best-move word, moves & hint-share, and a hint-count fix (#81) ... The statistics screen gains real depth, plus a hint-count bug fix found along the way. - Best move per variant: the screen shows the actual best-move word (drawn as game tiles; a wildcard shows its letter but no value), broken down by game variant, empty variants omitted. New account_best_move table, written at game finish. - Moves & hint share: two new lifetime tiles — the player's play count and the share of plays that used a hint — from summed account_stats counters (moves, hints_used). Honest-AI games are excluded, like the rest of the stats. - Hint-count fix: the in-game hint badge no longer goes stale across games. The global wallet now rides the wire apart from the per-game allowance (wallet_balance on StateView/HintResult/StatsView), so the client reads the live wallet rather than a per-game snapshot; game_players.hints_used now counts every hint (allowance + wallet), its true per-game total. - Account merge: sums the new moves/hints_used counters and merges the per-variant best moves (higher score kept), which it previously dropped. - Admin: the user card shows Moves and Hints used. - UI polish: tab/label wording, game-over text, and e2e selectors hardened against label changes. All wire additions are trailing (backward-compatible). Docs (ARCHITECTURE, FUNCTIONAL +ru, UISN_DESIGN) updated in step.	2026-06-17 22:17:27 +00:00
Ilia Denisov	2f4aa1b75b	feat(lobby): drop left honest-AI games from the finished list ... A finished honest-AI (vs_ai) game the player left — by resigning or by abandoning it to the 7-day inactivity timeout (end_reason 'resign'/'timeout') — no longer appears in that player's own lobby finished list. The new game.Service.ListForLobby filters ListForAccount for the lobby endpoint only; the admin console and the account-merge count keep the full set. The filter keys on the game's end reason, not on which seat left, so it extends to any player should the robot ever resign.	2026-06-17 13:03:35 +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	12d128f1cc	feat(nudge): name the sender; blink lobby cards; re-animate toasts ... The "waiting for your move" popup was the nudge (chat.nudge), shown without a sender name. Resolve the nudger's per-game seat name server-side and carry it on a new NudgeEvent.sender_name field, so: - the in-app toast reads "<opponent>: Waiting for your move 🤭" (chat.nudgeBy); - the out-of-app Telegram push names the sender too (render nudgeBy); falling back to the plain phrase when the name is absent (RU mirrored). The your_turn toast already named the opponent and is unchanged. Lobby: when a card transitions into "your turn" or "finished" while the lobby is open, its status emoji blinks twice (two 1s fades); the opponent's-turn change stays in place. Blink state is keyed by game id (SvelteSet + per-id nonce/timer) so overlapping events animate in isolation; suppressed under reduce-motion. Toast: a per-message seq re-keys Toast.svelte, so the freshest toast cancels the previous one and replays its entrance, uniformly on every screen. Tests: notify.Nudge round-trip + render named/fallback (Go), game.Service.SeatName (integration), codec/i18n/gamePhase/shouldBlink (UI). Docs (FUNCTIONAL +_ru, UI_DESIGN) + PLAN TODO-7 (deferred FLIP card-relocation animation) updated.	2026-06-16 19:09:24 +02:00
Ilia Denisov	183e08ec80	feat(robot): per-game display names from a wide name corpus ... Decouple the displayed opponent name from the small pool of durable robot accounts: the disguised auto-match robot now gets a freshly composed name each game, stamped on a new game_players.display_name seat snapshot. The snapshot also captures humans' names, freezing what an opponent sees for the life of a game (a later rename no longer rewrites past games); readers fall back to the account's current name for pre-migration rows. Names come from a wide composed corpus (internal/robot/namevariety.go): Western locales (EN/DE/ES/IT/FR/PT), native Japanese/Chinese names, a gender-agreed Russian pool, and human-style handles. Routing keeps Pick's spirit -- a Russian game draws Cyrillic + <=20% Latin and never a CJK script; an English game the full corpus -- via robot.PickNamed. Loosen account.ValidateDisplayName (and the UI mirror) to admit a trailing run of up to five digits, so "Player2007"-style handles are valid for humans too and the disguised robot stays indistinguishable. Migration 00007 adds game_players.display_name (additive, NOT NULL DEFAULT ''); jet regenerated. Docs (ARCHITECTURE 7, FUNCTIONAL + _ru, PLAN, README) updated.	2026-06-16 12:28:04 +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	02681ae9e0	feat(chat): limit in-game chat to one message per turn ... Enforce one chat message per turn on both ends. The backend rejects a second message in the same turn (ErrChatAlreadySentThisTurn -> 409 chat_already_sent), keyed on the move-driven turn start (turn_started_at). The UI derives "already wrote this turn" from the message list against GameView.lastActivityUnix (no counter, survives reopening, resets on turn change), hides the field behind a short caption once the limit is reached, and now reloads the game state on turn/game-state events so the toggle and the limit follow the live game. Enter is gated on !busy to avoid a double-send in the in-flight window. Backend: new game.TurnStartedAt; social GameReader gains it; PostMessage enforces the limit reusing lastMessageAt. UI: new lib/chatlimit.ts pure logic + unit tests; Chat/ChatScreen wiring; chat.sentThisTurn and error.chat_already_sent i18n (en/ru); extended chat e2e. Docs: FUNCTIONAL (+ru), ARCHITECTURE, UI_DESIGN.	2026-06-14 20:18:58 +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	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	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). Docs + PRERELEASE tracker updated.	2026-06-12 02:17:30 +02:00
Ilia Denisov	92f48a3b12	Backend infers play direction; UI previews words and gates submit on legality ... A single tile that only extended a word perpendicular to the client-declared direction was rejected: the UI always sent dir=H for one-tile plays (the dirOverride/Controls toggle was orphaned in the Stage 7 game rework), so placing "А" above "БАК" to form "АБАК" failed the solver's main-word-length check even though the word is in the dictionary. Make the backend infer a play's orientation from the placed tiles and the board (internal/engine.resolveDirection): two or more tiles by the line they share, a lone tile by the axis it abuts (longer word wins, horizontal on a tie). Direction becomes an output, not an input: drop dir from the SubmitPlay/Eval wire requests and add it to EvalResult. Journal replay keeps trusting the stored "H"/"V" (SubmitPlayDir) so a rebuilt game matches the one committed. UI: stop computing/sending direction; the preview now shows the words a move forms with its total score (game.previewWords); the make-move control is disabled until the play is confirmed legal; the "your turn" label hides while tiles are pending. Delete the orphaned Controls.svelte. Regenerate the FlatBuffers bindings (Go + TS) and update the gateway transcode and the loadtest edge client to the new contract. Bake the decision into ARCHITECTURE.md (§5/§9.1), FUNCTIONAL.md (+ _ru) and the backend README.	2026-06-11 22:42:33 +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	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	bf7dca0a09	Stage 17: fix the robot-nudge frequency + per-game push language ... Two owner-reported defects from a live contour game. A. Frequency: the robot's proactive nudge fired hourly for 12h+ (a 12h idle threshold then the 1h cooldown, uncapped). Replaced with a lengthening, randomized schedule (proactiveNudgeGap): the first nudge ~60-90 min into the human's turn, each later gap growing toward 1-6h (uniform sample in [60min, ceil], ceil ramping 90min->6h over 12h of idle, measured from the previous nudge), so a long wait gets a handful of increasingly-spaced reminders instead of a stream. B. Language: out-of-app push routed by the recipient's GLOBAL service_language (last-login-wins), so after re-logging via the RU bot an English game's nudges came from the RU bot. Now a game push (your_turn, game_over, nudge, match_found) carries the game's own language (engine.Variant.Language) on push.Event, and the gateway routes by it (falling back to service_language for non-game pushes). The New-Game variant-gating guarantees the game's bot is one the player has started, so delivery is never blocked. Tests: proactiveNudgeGap unit + retimed TestRobotProactiveNudge; TestVariantLanguage; emit your_turn/game_over language; TestNudgeRoutedByGameLanguage integration. Docs: ARCHITECTURE (§7 nudge, §10/§13 routing), FUNCTIONAL (+ _ru), PLAN tracker.	2026-06-09 08:06:58 +02:00
Ilia Denisov	f166ff30fe	Stage 17 #4: enrich the out-of-app your-turn push + add game-over ... The Telegram 'your turn' notification now names the opponent and recaps their last move (voiced as the opponent: «{name}: my move — «WORD». Score 120:95» for a scoring play; a short 'swapped / passed, your turn' otherwise), and a new game-over notification reports the result + final score when a game ends by any path (closing play, all-pass, resign, timeout). Scores are recipient-first (the reader's score leads), 2-4 players (120:95:80). - schema: YourTurnEvent gains opponent_name/last_action/last_word/score_line (appended, backward-compatible); new GameOverEvent{result, score_line}. Go + UI bindings regenerated (flatc 23.5.26 + pnpm codegen). - backend: notify.YourTurn enriched + notify.GameOver; emitMove resolves the mover's name and emits per-recipient (your_turn to the next mover, game_over to every seat), with recipient-first score lines built in one place. - gateway: game_over joins the out-of-app whitelist (routing.go). - connector: render builds the enriched your_turn + game_over text per language (en/ru). - tests: notify round-trip (enriched + game_over), emit (enriched fields + game_over to all seats / per-seat result), connector render (en/ru), routing; integration replay (play → your_turn with real name; resign → game_over) green. - docs: ARCHITECTURE push catalog + out-of-app set, FUNCTIONAL (+ _ru), PLAN tracker.	2026-06-09 01:15:18 +02:00
Ilia Denisov	4999478ded	Stage 17 #5: hide finished games from your own lobby list ... A player can remove a finished game from their own 'my games' list. The action is per-account, finished-only and irreversible (the game stays for the other players; there is no un-hide). - backend: migration 00012 game_hidden(account_id, game_id); store HideGame + hiddenGameIDs + ListGamesForAccount filtering; service HideGame (seat + finished checks, reusing ErrNotAPlayer / ErrGameActive); POST /api/v1/user/games/:id/hide. - gateway: game.hide edge op (reuses GameActionRequest -> Ack) + backendclient.HideGame. - ui: finished rows reveal a delete via swipe-left (touch) or a kebab tap (desktop), active rows get an inert chevron for icon alignment; optimistic removal + lobby-cache sync; mock + transport + client wiring; lobby.hideGame label (en/ru). - tests: integration (active->ErrGameActive, outsider->ErrNotAPlayer, per-account, idempotent), gateway transcode round-trip, mock e2e (kebab -> delete); hardened a pre-existing chat-screen .back transition flake surfaced by the new test's timing. - docs: ARCHITECTURE persistence list, FUNCTIONAL (+ _ru) lobby story, PLAN tracker.	2026-06-09 00:26:35 +02:00
Ilia Denisov	06c8039281	Stage 17 round 6 (#4/#5/#6 backend): per-game draft store + conflict reset ... Foundation for persisting a player's client-side composition: a game_drafts table (game_id, account_id, rack_order, board_tiles jsonb) with raw-SQL store/service methods — GetDraft/SaveDraft (seated-player check) and, on every committed move, clearing the actor's own draft and resetting any opponent's board draft whose cell the play overlapped (the draft can no longer be placed; the rack order is kept). Integration tests cover the round-trip, the actor clear, the overlap reset, a non-conflicting survival, and the outsider rejection. The gateway op slice + UI wiring follow.	2026-06-07 12:29:32 +02:00
Ilia Denisov	cdf616d6c4	Stage 17 round 6 (#7): reset the nudge cooldown once the player acts ... The hourly nudge cooldown now clears as soon as the sender has moved or posted a chat since their last nudge — engagement lifts the 'don't spam' limit. Backend: Nudge checks game.LastMoveAt + the sender's last non-nudge chat against the last nudge time (GameReader gains LastMoveAt). UI: nudgeOnCooldown mirrors it — a chat reset is read from the message list, a move is tracked client-side (lastActedAt on commit/pass/exchange; the backend stays authoritative across a reload). Integration test covers the reset.	2026-06-07 11:32:08 +02:00
Ilia Denisov	f916d5e0ca	Stage 17 round 5 (L2): robot play-to-win intent + next-move ETA in the admin game card ... The admin game detail now shows, per robot seat, the game's deterministic play-to-win decision (from the bag seed) and — while it is that robot's turn — its scheduled next-move ETA (sampled think-time delay, deferred past the sleep window), plus a caption with the ~40% global target. Wiring: robot.PlayToWin/NextMoveAt/PlayToWinTargetPercent exports, account.IsRobot, game RobotSchedule (seed + turn-start). Tests: NextMoveAt invariants (never early, never in the sleep window), PlayToWin export, and an admin render integration test asserting the intent + ETA + target appear.	2026-06-07 09:42:23 +02:00
Ilia Denisov	10412fee8e	Stage 17 round 5 — backend/correctness bug fixes ... - Resign on the opponent's turn: engine ResignSeat(seat) resigns a specific seat (not just toMove); game.Resign bypasses the turn check and forfeits the actor's seat. - Quick-match cancel was a UI no-op (only stopped polling): add the full path (REST /lobby/cancel -> gateway lobby.cancel -> client) and clear the matchmaker's pending result on Cancel, so a cancelled search is dequeued (no 'already queued', no later robot-substituted game). NewGame dequeues on cancel and on abandon. - Lobby win/loss: result.ts ranked by score, so a 0-0 resignation read as a win. The winner now takes rank 1 and the viewer is placed from rank 2 — matching the game-detail screen. - Friend request to a robot: robots no longer block requests; the request stays pending and expires (friendRequestTTL), mirroring a human who ignores it. - Nudge cooldown: ErrNudgeTooSoon now maps to a distinct nudge_too_soon code with a correct message; the chat nudge button disables during the hourly cooldown; the nudge note reads 'Waiting for your move!' (button keeps the Nudge action label). Tests: engine/service off-turn resign, matchmaker cancel-clears-result, friend-to-robot inttest, result.ts 0-0 resignation, nudge_too_soon mapping.	2026-06-07 09:17:35 +02:00
Ilia Denisov	635f2fd9fc	Stage 17: backend defect fixes (nudge code, TG name, robot names/timing, multi-device push, move-duration metric + admin analytics) ... - #3 nudge-on-own-turn: distinct result code nudge_own_turn + i18n (was reused 'not_your_turn') - #2 sanitize connector registration name to the editable format; Player/Игрок-XXXXX fallback - #5 variant-aware robot name pools (composed full/colloquial first + surname forms; ru gets <=20% latin) - #4 move-number-aware robot move timing (early 1-5min -> late 10-90min, skew k=4) - #7 emit move event to the actor too (multi-device sync); opponent_moved stays in-app only - #1 live game_move_duration{variant,phase} histogram + admin console per-user min/avg/max columns and an inline-SVG move-time-by-move-number chart (offline from the journal) - ProvisionRobot bypasses editor name validation (system names like 'Peter J.')	2026-06-06 09:59:12 +02:00
Ilia Denisov	90eaf4964b	Stage 13: alphabet on the wire (UI alphabet-agnostic, TODO-4) ... Live play now exchanges per-variant alphabet indices instead of concrete letters (rack out; submit-play, evaluate, exchange, word-check in). The client caches each variant's (index, letter, value) table behind StateRequest.include_alphabet and renders the rack and blank chooser from it, dropping the hardcoded value/alphabet tables. History, the durable journal and GCG stay decoded concrete characters (ARCHITECTURE §9.1, unchanged). - pkg/fbs: new AlphabetEntry + PlayTile; StateView.rack -> [ubyte] + alphabet; StateRequest.include_alphabet; SubmitPlay/Eval tiles -> [PlayTile]; Exchange tiles + CheckWord word -> [ubyte] (committed Go + TS regenerated). - engine: AlphabetTable + a cached per-variant codec (LetterForIndex/EncodeRack/ DecodeTiles/DecodeWord) + BlankIndex sentinel; Go parity test. - backend server edge maps index<->letter (new thin game.Service.GameVariant); game.Service domain methods, engine.Game and the robot keep one letter-based play path. The gateway forwards indices verbatim (no alphabet table). - ui: lib/alphabet.ts in-memory cache; codec encodes/decodes indices; premiums.ts is geometry-only; the mock seeds a fixture table; the UI normalises display to upper case (codec + cache), leaving placement/board/checkword unchanged. Parity moved to the Go engine.AlphabetTable test; premiums.ts loses its value tables. Discharges TODO-4.	2026-06-04 16:26:43 +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	d733ce3119	Stage 8: UI social/account/history surfaces ... Wire the deferred Stage 7 surfaces end-to-end (UI -> gateway transcode -> backend REST -> existing domain services): friends (incl. one-time friend codes), per-user blocks, friend-game invitations, profile editing + email binding, the statistics screen, and the in-game history + GCG export. Friends gain two add paths (interview decision, a deliberate plan change): one-time 6-digit codes (friend_codes table, 12h TTL, single-use, rate-limited redeem); and play-gated requests (shared game required) where an explicit decline is permanent, an ignored request lapses after 30 days, and a code bypasses a decline. Migration 00006 widens friendships_status_chk and adds friend_codes. Lobby notification badge is poll + push: a new generic `notify` event drives it live; the client polls on open/focus. Language stays a single Settings control that writes through to the durable account's preferred_language. GCG export is finished-only (game.ErrGameActive) and shares/downloads the .gcg file. Tests: backend unit + inttest (friend gate/decline/code, ListInvitations, GetStats, GCG gate), gateway transcode round-trips + notify constructor, UI vitest (codecs, win-rate, share choice) + Playwright social specs. Docs: PLAN (Stage 8 done + refinements + TODO-5), ARCHITECTURE, FUNCTIONAL(+ru), UI_DESIGN, TESTING, module READMEs.	2026-06-03 19:47:40 +02:00
Ilia Denisov	65689b903f	Stage 7 (wip): wire remaining ops (backend REST, FBS, gateway transcode) + real UI transport ... backend: REST handlers for pass/exchange/resign/hint/evaluate/check_word/complaint/history/chat-list/nudge + new game.ListForAccount (my games) + seat display_name resolution pkg/fbs: GameActionRequest/ExchangeRequest/EvalRequest/EvalResult/CheckWordRequest/WordCheckResult/ComplaintRequest/HintResult/History/GameList/ChatList + SeatView.display_name; committed Go regenerated (flatc 23.5.26) gateway: 11 new transcode ops + backendclient methods + FB encoders ui: edge TS codegen (flatc --ts + protoc-gen-es, committed), FlatBuffers<->model codec, real connect-web transport (binary, bearer auth, Subscribe). prod bundle ~69KB gzip JS	2026-06-03 00:49:07 +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
Ilia Denisov	85baabe4ba	Stage 5: robot opponent (pool, seed-derived strategy, move driver, matchmaker substitution) ... - internal/robot: durable kind='robot' account pool (migration 00004); every per-game and per-turn choice derived deterministically from the game seed (restart-stable FNV mix); a background move driver; margin targeting (band 1-30, closest-to-band); right-skewed [2,90]min delays (median ~10m); opponent-anchored sleep with +/-3h drift; daytime nudge reply + proactive 12h nudge; friend/chat blocked via profile toggles. - engine.Candidates (decoded ranked plays); game.Candidates + RobotTurns; social.LastNudgeAt. - matchmaker: 10s wait then robot substitution (reaper) + Poll delivery seam. - config (BACKEND_ROBOT_DRIVE_INTERVAL, BACKEND_LOBBY_ROBOT_WAIT, BACKEND_LOBBY_REAPER_INTERVAL); main wiring + boot-time pool provisioning. - metrics: robot account_stats (authoritative balance) + robot_games_finished_total OTel counter + per-finish log. - docs: PLAN, ARCHITECTURE, FUNCTIONAL(+ru), TESTING, README; account.go comment. - tests: robot strategy units, matchmaker reaper/Poll, engine.Candidates; inttest robot full-game / substitution / proactive-nudge.	2026-06-02 21:02:20 +02:00
Ilia Denisov	bfa8797f8c	Stage 4: lobby & social (matchmaking, friends, blocks, chat+nudge, invitations, profile, email, multi-player drop-out) ... Engine: multi-player drop-out-and-continue with a per-game tile disposition (remove default / return), resigned seats skipped and excluded from the win, leaver rack never revealed; 2-player behaviour unchanged. New domains (service/store, no HTTP yet): internal/social (friend request/accept graph, per-user blocks, per-game chat with nudge as a message kind, content filter via mvdan.cc/xurls/v2 + leet/separator normaliser + phone heuristic) and internal/lobby (in-memory variant-keyed matchmaking pool, friend-game invitations invite->accept with lazy 7-day expiry). account gains profile editing and the email confirm-code flow (Mailer seam: SMTP or log mailer). Migration 00003_social.sql + regenerated jet. main wires the new services into the server (accessors for the Stage 6 handlers); robot substitution stays in Stage 5, REST/stream/push in Stage 6/8. Docs (PLAN, ARCHITECTURE, FUNCTIONAL+ru, TESTING, README) updated.	2026-06-02 19:29:30 +02:00
Ilia Denisov	751e74b14f	Stage 3: game domain (lifecycle, journal+cache, hint, word-check, GCG, stats) ... internal/game drives the engine over a single match and owns everything the engine does not: event-sourced persistence (a games row + an append-only decoded move journal, with the live engine.Game kept warm in a cache and rebuilt by replay on a miss), the play/pass/exchange/resign transitions with validate-at-submit scoring, an unlimited score/legality preview, the hint (per-game allowance + profile wallet), the word-check tool with complaint capture, per-player game state, history and GCG export (Poslfit dialect), and a background turn-timeout sweeper that auto-resigns overdue turns honouring each player's daily away window. Like Stages 1-2 it is a service/store layer with no HTTP; the gateway surface lands in Stage 6. Engine: additive decoded domain API (Direction, SubmitPlay/SubmitExchange/ EvaluatePlay/HintView/Hand, MoveRecord.{Dir,MainRow,MainCol}, Registry.Lookup, ParseVariant) so internal/game never imports scrabble-solver; and a Resign fix so the resigner keeps their score yet never wins (the other player wins a two-player game). Timeout reuses Resign. Persistence: migration 00002 adds games, game_players, game_moves, complaints, account_stats and extends accounts with away_start/away_end/hint_balance; go-jet regenerated. account gained SpendHint. Config adds BACKEND_DICT_DIR (required), BACKEND_DICT_VERSION, BACKEND_GAME_TIMEOUT_SWEEP_INTERVAL, BACKEND_GAME_CACHE_TTL; main loads the registry at boot (hard dependency) and starts the sweeper. Tests: engine resign + decoded-API tests; game unit tests (GCG, away-window boundaries, hint budget, cache, keyed mutex, payload); inttest integration (lifecycle, replay equivalence, timeout sweep with away grace, resign stats, hint policy, word-check/complaint, per-game-lock). Docs (PLAN, ARCHITECTURE, FUNCTIONAL +_ru, TESTING, README) updated.	2026-06-02 17:33:49 +02:00
