Ilia Denisov	ed53e25e57	feat(backend): per-tier, per-kind active-game limits with a guest funnel ... Cap a player's simultaneous unfinished games per kind (vs_ai, random, friends) with independent guest and durable-account tiers, held in a new single-row backend.config table (-1 = unlimited) behind an in-memory cache and editable live in the admin console (/_gm/limits). Each game is tagged with games.game_kind on creation. This replaces the earlier flat MaxActiveQuickGames=10 combined cap: the per-tier/kind config is the single mechanism, enforced at the same handler gate (ensureUnderGameLimit by kind on lobby/enqueue) plus the durable friends cap in CreateInvitation. game.Service.AtGameLimit only resolves the tier and counts; the limit policy stays at the request edge. Guests are now refused friend requests, friend-code redemption, befriend-in-game and invitation creation outright (403 guest_forbidden) -- previously only the UI hid these. Admin: a kind column in both game lists and the config editor. Defaults: guest 1 vs_ai / 1 random / 0 friends; durable 10 / 10 / 10.	2026-07-10 09:03:57 +02:00
Ilia Denisov	8d2cd97e17	feat(adminalert): operator email on new feedback / word complaints ... New adminalert worker polls for feedback + word complaints arriving since the last check and coalesces a burst into one digest email per interval (5 min), inert unless a distinct admin sender (BACKEND_SMTP_ADMIN_FROM) and recipient (BACKEND_ADMIN_EMAIL, comma-separated allowed) are configured. The mailer gains a per-message From override and splits a comma-separated To into separate recipients (go-mail needs them as a list). Feedback/game stores gain CountSince/CountComplaintsSince. Unit tests cover the digest, the skip-when- empty, and the recipient split.	2026-07-03 14:53:51 +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	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	f3768d20f2	feat(robot): shrink endgame think time when both sides pass ... In a dead-drawn endgame — the two most recent journal moves are both passes, so the board and the robot's rack are frozen and the robot is bound to pass again — the robot still waited out its long late-game think time (up to 90 min) before passing, needlessly dragging out a decided game. Shorten that delay to a [0.8, 1.5]x band around the human's last-move think time (the gap between the last two journal entries), clamped to [30s, 8min] and taken as a min with the normal schedule, so the robot never moves slower. A slow human collapses to the 8-min cap; a fast human is tracked, with the floor keeping the robot from passing suspiciously instantly. The anchor reads the move journal only (no schema change), stays deterministic from the seed, and still defers to the sleep window. RobotTurns now carries EndgamePass + OppLastMove, filled by one batched journal query on the scan; the honest-AI single-game trigger keeps the normal path (it moves at once). NextMoveAt (admin ETA) is left as the normal-schedule upper bound.	2026-06-19 12:48:39 +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	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	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	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	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	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	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	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	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	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.

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).

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).
