Ilia Denisov	5fa51d04d9	fix(engine): EvaluatePlay honors the single-word rule ... The move preview (EvaluatePlay) validated under standard rules — it called ValidatePlay without the game's play options — so under the single-word rule it rejected a play whose only flaw was incidental invalid perpendicular cross-words, even though SubmitPlay accepts it. The UI gates the submit button on the preview, so such a play (e.g. КРАН bridging an existing Р on the test contour) could not be made. Pass g.playOpts() via ValidatePlayOpts, mirroring Play, so the preview's legality and score match submission. Robots are unaffected — they search via GenerateMovesOpts and submit via Play, both already opts-aware — and a regression test asserts that too.	2026-06-12 11:14:20 +02:00
Ilia Denisov	0b57400c6f	feat(ui): single-word rule indicators + auto-match select redesign ... Surface the per-game "single word" rule to the client and refine the random-opponent New Game screen. - Wire: thread multiple_words_per_turn into the GameView and Invitation FlatBuffers tables (Go + TS regenerated), through pkg/wire builders and both the backend push-event and gateway REST paths. - In-game indicators (single-word games only): a small 1 in the status bar's score-preview slot (yields to the live preview) and a centred "One word per turn" label in the history-drawer header. Standard games show neither. - Invitation card gains a "One word per turn" line for single-word invitations. - Auto-match redesign: variant plaques are mutually-exclusive selects (highlight on tap, no longer enqueue); a lone offered variant is pre-selected; a bottom "Start game" button (disabled until a variant is chosen) confirms. The rule toggle appears once a Russian variant is selected. - Tests: e2e for the new auto flow and the in-game indicator (mock g3 is a single-word game); mock/data + fixtures carry the new field. Docs: UI_DESIGN.	2026-06-12 10:28:29 +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	e68fe61e39	UI: render move history as a per-seat column grid + swipe-down to open ... Replace the flat chronological move list with a ruled matrix aligned under the score plaque: one column per seat, each seat's moves filling its column top to bottom. A cell is the move's word(s) and its score, "WORD (12)", centred; the player names and the running total are dropped (the plaque heads the column and shows the live total). Non-play moves keep their dim parenthesised tag; the awaited opponent's next cell shows a dim "thinking..." (never the viewer's own turn). Thin 1px rules between columns and rows match the panel's separator. Re-introduce a swipe-down-on-the-board gesture to open the history, gated to the zoom-out board scrolled to its top so it never fights the zoomed board's pan or the stage's own vertical scroll (the conflict that retired this gesture before). Grid layout extracted to lib/history.ts (unit-tested); add game.thinking to the EN/RU catalogs; e2e covers the gesture and the grid on Chromium and WebKit.	2026-06-11 20:18:23 +02:00
Ilia Denisov	ad91bc728b	UI: taller tg-fullscreen header + labelled hub tabs ... - tg-fullscreen: +20px header height — without the (removed) hamburger the title bar lost its bulk and sat flush on Telegram's native nav band. - Settings/Comms hub tabs gain text labels under the icons (Settings / Profile / Friends / Info and Chat / Dictionary); the icon is aria-hidden so the label names the button. New i18n keys about.tab, game.dictionary.	2026-06-11 15:12:40 +02:00
Ilia Denisov	fc1261e078	UI: tab-bar navigation — drop the hamburger ... 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	c31ac7088c	R6(b): reconcile docs with code — restore guest-reaper mention ... Pass (a) removed a stale "(reaping abandoned guest rows is deferred — TODO-3)" note from ARCHITECTURE §3, but guest reaping is implemented (the background reaper, BACKEND_GUEST_REAP_INTERVAL / BACKEND_GUEST_RETENTION, covered by inttest). State the current behaviour instead. A full section-by-section review of ARCHITECTURE / FUNCTIONAL (+_ru) / TESTING / UI_DESIGN against the code found no other drift — each R-phase baked its own docs, and FUNCTIONAL/TESTING already describe the reaper correctly.	2026-06-10 17:02:48 +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	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	aa137e3558	R2: load-test harness + contour resource observability ... New scrabble/loadtest module (the pre-release stress harness): seeds 1000 guest + 10000 durable accounts with pre-created sessions directly in Postgres (token hash matches backend/internal/session), drives virtual players through the edge protocol (real 2-4p games assembled via invitations, mid-ranked legal moves generated locally by the embedded scrabble-solver — the edge carries no board, so the client replays history), plus nudge/chat/check-word/draft/profile/stats and a gateway-hammer that verifies the rate limiter. Prints a trip-report summary (per-op latency percentiles, result codes, live-event tally). Go unit tests cover the pure pieces; the DAWG-backed move test runs under BACKEND_DICT_DIR. Contour: add cAdvisor + postgres_exporter + a 'Scrabble - Resources' Grafana dashboard and the two Prometheus scrape jobs, for the R2/R7 stress-run resource baseline. CI: gate ./loadtest/... (path filter + vet/build/test). Docs: TESTING, ARCHITECTURE, project CLAUDE repo layout.	2026-06-09 23:45:24 +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
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	d87c0fb10b	Stage 17: cap display-name special characters at 5 (ui + backend) ... display_name validation gains a rule: at most 5 special characters — the '.' / '_' punctuation (spaces, which separate words, don't count) — so a still-well-formed name can't be mostly punctuation. Mirrored in the Go ValidateDisplayName and the UI validDisplayName; both unit-tested (5 ok, 6 rejected, 'J. R. R. Tolkien' ok). Docs: FUNCTIONAL (+ _ru).	2026-06-09 07:42:47 +02:00
Ilia Denisov	ef61b778fc	Stage 17 #2: Connecting indicator + auto-retry, instead of red toasts ... Connectivity failures become state, not a toast on every attempt. A global online signal (lib/connection.svelte.ts) flips on a transport unavailable / rate_limited and on the live stream's drop, driving a pure-CSS header spinner + 'Connecting…' in place of the title and softly disabling the in-game server actions (commit / exchange / pass / hint; local board/rack/reset stay live). - transport: exec auto-retries with capped exponential backoff — every op on a rate-limit (rejected before processing, safe), reads only on unavailable (a mutation is never blindly re-sent, to avoid double-applying one whose response was lost; its button is disabled while offline so the player re-issues on reconnect). A reachability watcher (profile.get probe) and any successful traffic clear the signal. - the old red error.unavailable toast is gone (handleError suppresses connection codes; the indicator replaces it). A server-data screen still opens with the spinner and fills on reconnect (global indicator + read auto-retry), so navigation is never dead. - pure retry policy unit-tested (retry.ts); a mock-only window.__conn hook drives a Chromium+WebKit e2e (indicator shows offline, the action disables, both clear on reconnect). Full suite + build green. - docs: ARCHITECTURE transport note, FUNCTIONAL (+ _ru), PLAN tracker (incl. #1 — the bot already drains all updates, no change). Also records #1 as investigated/no-change in PLAN. Other server-action buttons (chat send, profile save, …) still degrade to a safe no-op offline; visual disable is easy to extend.	2026-06-09 01:48:20 +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	70110effd9	Chat + word-check as their own screens; in-game unread badge (review item 7) ... - Chat and word-check are now routed screens (/game/:id/chat, /game/:id/check) with a header back to the game and no tab-bar, replacing their modals. The soft keyboard just resizes the visible viewport (tracked into --vvh, which the Screen height uses since iOS does not shrink dvh for the keyboard) with the input pinned to the bottom: no modal relayout, no page jump. Supersedes the earlier bottom-sheet Modal attempt. - A new chat message raises an unread badge on the in-game hamburger + the Chat menu row (per game, cleared on opening the chat), mirroring the lobby badge. - TG native back + the header back chevron return chat/check to their game. - Exposes --tg-safe-top (device notch) for the finalised TG-fullscreen header. Tests: e2e for chat/check opening as their own screens + back. Docs: PLAN, FUNCTIONAL(+ru).	2026-06-08 23:23:05 +02:00
Ilia Denisov	645df52c0b	Round-6 follow-up: UX polish + client-IP fix ... - Client IP: the compose caddy trusts X-Forwarded-For from private-range upstreams (trusted_proxies private_ranges), so the real client IP survives the host-caddy hop (it was logging the docker caddy hop 172.18.0.x for chat moderation and bucketing the gateway per-IP rate limiter on it). Correct and spoof-safe in both contours (prod has no host caddy); peerIP unit-tested. - Ad banner gated off behind a compile-time SHOW_AD_BANNER=false (the if-branch, the AdBanner import and banner.ts are tree-shaken out of the prod bundle). - Landing: the Telegram entry is just the 64px logo (clickable, no button/text). - TG-fullscreen header: title + menu centred as a pair (hamburger right of the title), pinned to the bottom of the TG nav band. - Edge-swipe back (Screen): a left-edge rightward drag navigates to back (touch/pen only, armed from <=24px; skipped inside Telegram). - Chat soft-keyboard: a bottom-sheet Modal lifted above the keyboard by a visualViewport-driven transform (compositor-only, no page/sheet relayout). iOS-specific, needs on-device tuning; native resize=none awaits Capacitor. - Tests: e2e for the in-game '✓ in friends' item and a board→board tile relocation; codec units for last_activity_unix + OutgoingRequestList. Deferred to the next PR (agreed): #4 enrich the your-turn/game-end push; #5 hide finished games from the lobby.	2026-06-08 21:31:44 +02:00
Ilia Denisov	356f490546	Stage 17 round 6 (#18, PR D): admin Messages moderation section ... A new /_gm/messages console page lists posted chat messages (nudges excluded) newest-first — time, source (guest/robot/oldest identity kind), sender (linked to the user card), IP, body, game (linked to the game card) — searchable by sender name / external-id glob masks and pinnable to one game (?game=) or sender (?user=), linked from the game and user cards. The list query lives in social (raw SQL, kind='message', source via a SQL CASE), reusing the now-exported account.LikePattern. Server-rendered adminconsole MessagesView + messages.gohtml, 50/page via the shared pager. Tests: adminconsole render case; backend integration AdminListMessages (real Postgres) — nudge exclusion, game/sender pins, glob masks, source. Docs: ARCHITECTURE section 8 chat moderation, PLAN round-6.	2026-06-08 20:10:27 +02:00
Ilia Denisov	6b6baf5710	Stage 17 round 6 (#16/#17, PR C): lobby sort + server-derived in-game friend state ... Lobby: group the my-games list into your-turn / opponent-turn / finished (empty sections hidden), ordered by last activity (your-turn oldest-first, the other two newest-first), as a compact line-separated list. gameDTO and FB GameView gain last_activity_unix (turn start while active, finish time once finished); a pure lib/lobbysort.ts holds the grouping/ordering. Friends: the in-game 'add to friends' item is now server-derived via a new GET /user/friends/outgoing (+ friends.outgoing op), returning addressees with a pending OR declined request (both read as 'request sent'), so it is correct across reloads; it shows a disabled '✓ in friends' once accepted. It live-updates when the opponent answers: RespondFriendRequest now publishes friend_added (accept) / friend_declined (new notify sub-kind, decline) to the original requester, whose open game re-derives its friend state. Tests: lobbysort unit test; gateway outgoing + last_activity transcode tests; backend integration ListOutgoingRequests + respond-publishes-to-requester; e2e updated for the new lobby section labels + a non-friend active opponent. Docs: ARCHITECTURE notify catalog, FUNCTIONAL(+ru) lobby/friends, PLAN.	2026-06-08 19:23:48 +02:00
Ilia Denisov	3fd279cf8c	Landing v2: icon switchers, ephemeral theme, channel link, drop browser CTA ... Owner review-pass rework of the landing page: - Rename the per-language Telegram link build var VITE_TELEGRAM_LINK_EN/_RU -> VITE_TELEGRAM_GAME_CHANNEL_NAME_EN/_RU (it carries a channel username; the landing builds https://t.me/<name> -- the same channels the connector posts to via TELEGRAM_GAME_CHANNEL_ID_*). - Language switcher -> a globe icon dropdown (flags + names), saved + synced to the app prefs. - Theme switcher -> a sun/moon icon toggle, ephemeral (follows the system scheme, no auto, never persisted) -- galaxy-game style. - Drop the "Play in browser" CTA (no standalone-web onboarding yet). Docs: FUNCTIONAL(+ru), PLAN, deploy + ui READMEs.	2026-06-08 16:40:07 +02:00
Ilia Denisov	e16076c89e	Stage 17 round 6 (#16-20): landing page, /app/ move, cache + stream fixes ... Close out Stage 17 round 6: - Landing page at / — one Vite build with two entries (index.html = game SPA, landing.html = a lightweight landing reusing the theme/i18n/ aboutContent leaf modules, not the app store). - Move the web game SPA to /app/; the Telegram Mini App stays at /telegram/ (gateway webui.Handler(stripPrefix, indexName): landing at /, SPA at /app/ + /telegram/). Per-language "Play in Telegram" link via new VITE_TELEGRAM_LINK_EN/_RU build vars (button hides when unset). - Cache headers: hash-named /assets/* immutable, HTML shells no-cache (the go:embed zero modtime emitted no validators, so the client re-downloaded the whole bundle every launch). - Live-stream 15s abort fix: an immediate heartbeat on open + a 10s default interval (the first tick at 15s raced the edge idle timeout -> reconnect storm). PLAN/ARCHITECTURE(§13)/FUNCTIONAL(+ru)/gateway+ui+deploy READMEs updated; round 6 closed. Tests: gateway webui/connectsrv units, ui landing unit + e2e, full e2e (60) green.	2026-06-08 13:33:05 +02:00
Ilia Denisov	a420d6a2cd	Stage 17 round 5 docs: bake the bug fixes + UI polish + L2 into live docs ... - ARCHITECTURE: resign on the opponent's turn (ResignSeat + turn-check bypass); robots block chat but accept-and-ignore friend requests; quick-match /lobby/cancel; the admin robot play-to-win intent + next-move ETA panel. - UI_DESIGN: even A->B zoom (recentre only on zoom-in), pinch, drop-target highlight, shuffle ≤0.3s + reduce-motion, borderless make-move disabled on illegal, variant title. - FUNCTIONAL (+ru): variant display names (Scrabble/Erudite); robot ignores friend requests. - PLAN: round-5 refinements bullet (+ the bilingual two-Scrabble open edge).	2026-06-07 09:48:08 +02:00
Ilia Denisov	3856b34f8a	Stage 17 docs: round-4 UI (inline profile, double-tap/drag recall, hover-zoom, animated shuffle, lines-off board) ... - UI_DESIGN: double-tap recall vs zoom, hover-hold drag auto-zoom, placing & recall rules, grid-lines toggle (gapless checkerboard default), animated shuffle; fix the stale MakeMove/Reset description (direct ✅ button + ↩️ Reset tab, no popover). - FUNCTIONAL (+ru): optional trailing '.' in display names; profile edited inline. - PLAN: robot early band [1,5]→[3,10] (#14); round-4 refinements + deferred #2/#16.	2026-06-06 14:55:17 +02:00

Ilia Denisov	f6bffd1f57	Stage 17 (contour round 3): Telegram Mini Apps polish, board scroll, keyboard overlay ... - Telegram (lib/telegram.ts): chrome colours (setHeaderColor/setBackgroundColor/setBottomBarColor) match Telegram's header/bg/bottom bar to the app; native BackButton on sub-screens (app chevron hidden in TG); HapticFeedback on tile place/commit/error; enableClosingConfirmation while a game is open; disableVerticalSwipes so swipe-to-minimise doesn't fight tile drag / board scroll - #9 board-only vertical scroll: Screen 'column' mode lets the board area scroll while score/status/rack/tab bar stay fixed (zoom keeps its own scroll) - #10 check-word dialog opens in Modal keyboard-overlay mode (top-anchored, keyboard overlays the empty area) — no resize/relayout jank; other modals stay keyboard-aware - docs: UI_DESIGN Telegram integration + vertical fit/keyboard; PLAN round 2-3 follow-ups	2026-06-06 12:55:46 +02:00
Ilia Denisov	09fec2b83c	Stage 17: bake decisions into PLAN, ARCHITECTURE, FUNCTIONAL(+ru), UI_DESIGN, READMEs; mark stage done ... - PLAN: Stage 17 Refinements entry + caveats resolved summary + tracker done - ARCHITECTURE §7 (move-number robot timing, composed variant-aware names), §10 (move event to the actor too), §11 (game_move_duration metric + offline admin per-user analytics), §14 (current branch model, path-conditional CI + gate, connector liveness) - FUNCTIONAL(+ru): robot draws language-appropriate names - UI_DESIGN: screen transitions, Telegram theme/nav, ad-banner accent, players plaque + history drawer - backend README: robot timing/names refinements	2026-06-06 10:31:22 +02:00
Ilia Denisov	4a07d48a7b	Fix Grafana dashboards mount; keep connector OTLP (AWG_CONF must omit DNS=) ... - deploy/docker-compose.yml: mount the provisioned dashboards at /etc/grafana/dashboards, not /var/lib/grafana/dashboards — the grafana-data volume mounts over the latter and shadows the nested bind, so the provider logged "readdirent /var/lib/grafana/dashboards: no such file or directory". dashboards.yaml provider path updated to match. - Connector telemetry stays OTLP. The VPN sidecar's netns reaches the collector's internal IP fine (connected route, off-tunnel), but the sidecar's DNS hijacks name resolution: AWG_CONF must NOT carry a DNS= directive, else otelcol won't resolve ("produced zero addresses"). Without DNS= the netns uses Docker's resolver (resolves both otelcol and api.telegram.org). Documented in deploy/README.md (AWG_CONF row + wiring note), ARCHITECTURE §13, compose comment.	2026-06-05 17:34:33 +02:00
Ilia Denisov	efbaf657c6	Stage 16: insert Stage 17 (test-contour verification); renumber prod deploy to 18 ... - PLAN.md: new Stage 17 "Test-contour verification & defect fixes" (exercise the deployed contour end-to-end and fix what it surfaces — connector liveness check, path-conditional CI); the former prod-deploy stage becomes Stage 18. - Renumber every "Stage 17" prod-deploy reference to "Stage 18" across docs, compose, Caddyfile, ci.yaml and CLAUDE.md; the post-Stage-14 split range is now "Stages 15–18".	2026-06-05 16:57:17 +02:00
Ilia Denisov	8700fbfae1	Stage 16: deploy infra & test contour ... - backend + gateway multi-stage distroless Dockerfiles; the gateway embeds and serves the SPA at / and /telegram/ via go:embed (committed dist placeholder, real build baked in by the image's node stage) - deploy/docker-compose.yml: backend + gateway + Postgres + Telegram connector (VPN sidecar) + OTel Collector + Prometheus (15d) + Tempo (72h) + Grafana, fronted by a caddy owning a single /_gm Basic-Auth (admin console + Grafana subpath); inter-service on a private network, only caddy on the edge network - new metrics: backend accounts_created_total{kind} (robots excluded) and an in-memory gateway active_users{window=24h,7d} gauge - CI: single .gitea/workflows/ci.yaml (unit/integration/ui + a gated test-contour deploy) on the new feature/* -> development -> master branch model; the old go-unit/integration/ui-test workflows are folded in; the connector-scoped compose is retired (superseded by deploy/) - docs: ARCHITECTURE §11/§12/§13, root + gateway READMEs, CLAUDE.md branching, PLAN.md (stage 16 done + refinements + Stage 17 forward-notes)	2026-06-05 11:42:26 +02:00
Ilia Denisov	e9f836db87	Stage 15: dual Telegram bots & language-gated variants ... Service-agnostic refinement of the owner's idea: the sign-in service returns a set of supported game languages with the user identity, and the lobby gates the New Game variant choice by it (en -> English; ru -> Russian + Эрудит). - Connector hosts two bots in one container (one per service language, each its own token + game channel; the same telegram_id spans both). ValidateInitData tries each token and returns the validating bot's service_language + supported_languages. Per-language config (TELEGRAM_BOT_TOKEN_EN/_RU, channels). - supported_languages rides the Session (fbs, session-scoped, not persisted); the UI offers only the matching variants on New Game — gating only the START of a new game (auto-match + friend invite), not accept/open/play; backend does not enforce. - service_language persisted (accounts.service_language, migration 00010, written every login, last-login-wins) and routes the user-facing Notify push back through the right bot (push-target coalesces with preferred_language). - Admin SendToUser/SendToGameChannel gain an operator-chosen language selector in the console (unrelated to ValidateInitData). - Non-Telegram logins carry the gateway default set (GATEWAY_DEFAULT_SUPPORTED_LANGUAGES, all variants). Wire (committed regen): ValidateInitDataResponse +service_language +supported_languages; Session +supported_languages; SendToUser/SendToGameChannel +language. Docs (ARCHITECTURE/FUNCTIONAL/_ru/READMEs) + PLAN updated; stage marked done.	2026-06-05 09:35:53 +02:00
Ilia Denisov	ec435c0e7f	Stage 14: solver & dictionary split — consume published module + DAWG artifact (TODO-1/TODO-2) ... - backend/go.mod pins gitea.iliadenisov.ru/developer/scrabble-solver v1.0.0; the engine's imports use the published module path; go.work drops the solver replace (GOPRIVATE fetches it directly from Gitea). The solver's wordlist/dictdawg are now public packages. - CI (go-unit, integration): drop the solver sibling-clone, set GOPRIVATE, and download the dictionary DAWG release artifact (scrabble-dawg-<DICT_VERSION>.tar.gz from the new scrabble-dictionary repo) for BACKEND_DICT_DIR. - Docs: ARCHITECTURE §5/§11/§13/§14 + backend/README updated to the published-module + release-artifact model. PLAN.md re-scoped Stage 14 to the split and added Stages 15 (deploy infra & test contour), 16 (prod contour), 17 (dual Telegram bots); TODO-1/TODO-2 marked done.	2026-06-04 20:00:36 +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	01485d8fc6	Stage 11: account linking & merge (email + Telegram Login Widget) (#12)	2026-06-04 09:18:17 +00:00

Ilia Denisov	cf66ed7e26	Stage 9: Telegram integration (connector side-service, Mini App, out-of-app push) ... New platform/telegram connector (own container, bot token only there): - go-telegram/bot long-poll loop: /start deep-links + Mini App launch button. - gRPC API pkg/proto/telegram/v1 (Telegram service): ValidateInitData, Notify (renders a localized message + deep-link button), SendToUser/SendToGameChannel (admin, wired in Stage 10). Generic methods are platform-agnostic (external_id). - Bot API base override for Telegram's test environment; Dockerfile + compose (VPN sidecar, no public ingress); README. Gateway: - initData validation relocated from the gateway into the connector; the gateway calls ValidateInitData over gRPC (GATEWAY_CONNECTOR_ADDR), drops the bot token, and deletes internal/auth. - Out-of-app push: runPushPump routes events whose recipient has no live in-app stream to connector.Notify, gated by /internal/push-target + the in-app-only flag (race-free de-dup); HasSubscribers added to the push hub. Backend: - Migration 00007 accounts.notifications_in_app_only (default true) + jetgen. - ProvisionTelegram seeds a new account's language/display name from the launch fields; IdentityExternalID reverse lookup; /internal/push-target handler. UI: - Telegram Mini App launch: detect initData, apply themeParams, authTelegram, route the deep-link start_param (g/i/f); /telegram/ guard redirects outside Telegram. Vite relative base + telegram-web-app.js. In-app-only profile toggle; share-to-Telegram link for a friend code. Vitest + Playwright coverage. Wire/docs/CI: fbs Profile/UpdateProfileRequest gain notifications_in_app_only (Go + TS); go.work uses ./platform/telegram; go-unit.yaml covers it; PLAN, ARCHITECTURE, FUNCTIONAL (+ru), UI_DESIGN, READMEs updated.	2026-06-04 07:10:21 +02:00
Ilia Denisov	acbb2d8254	Stage 8 polish: profile validation, finished-game UI, badge + Safari fixes ... Owner-review follow-up on the Stage 8 branch: - Friend code is copyable (📋 + toast). The lobby notification badge is fixed — it had inherited the hamburger-bar style — into a proper round count dot. - Safari: min-width:0 on flex text inputs (friend code, profile, chat) so they shrink instead of pushing the adjacent button off-screen. - Profile editing is validated on both the UI and the backend: display-name format (letters joined by single space/./_ separators, no leading/trailing/adjacent separators, <=32 runes), a UTC-offset timezone picker (account.ResolveZone parses ±HH:MM or a legacy IANA name), a 10-minute away grid capped at 12h (wrap-aware), and email format; Save is disabled and invalid fields red-bordered until valid. Language stays in Settings. - In a game, an "add to friends" menu item flips to a disabled "request sent"; chat send/nudge became ⬆️/🛎️ icon buttons. - A finished game drops its last-word highlight, hides Check word / Drop game, disables zoom, and draws an inert (greyed) footer instead of hiding it. Tests: account validators (name/away/zone), UI profileValidation, e2e for the finished-game footer/menu and the copy control. Docs (PLAN, ARCHITECTURE, FUNCTIONAL +ru, UI_DESIGN) updated for the display-name rule, UTC-offset timezone and the 12h away window.	2026-06-03 22:12:59 +02:00
Ilia Denisov	2d82c75f0b	Stage 8: document the friend-code brute-force mitigation (ARCHITECTURE §12)	2026-06-03 19:51:58 +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. 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	52a0e3160d	Stage 7 polish (round 2): layout/zoom/tab-bar/hint/check fixes ... - nav bar grows ONLY in game (other screens: minimal nav, content fills); tab bar always bottom - tab bar: tighter icon/label spacing, bigger icons, hint badge on the icon corner - board zoom reworked to width-based (real native scroll, fixes Safari/Chrome) + constant cqw labels; pinch & swipe-to-history dropped (conflict), double-tap kept, history via menu - beginner bonus labels shrunk to fit cells - Draw opens exchange directly (no confirm); confirm popovers restyled like the hamburger dropdown (vertical); removed the floating direction toggle - pending tiles darker bg (no outline); last-word dark-tile highlight (static / 1s flash) - check button disabled for <2/>15 chars, already-checked, or 5s cooldown - global user-select:none (inputs exempt); docs updated; TODO-4 alphabet-on-wire	2026-06-03 14:54:41 +02:00
Ilia Denisov	92a4de3bf4	Stage 7 polish: docs + mark Stage 7 done (Part H) ... - new docs/UI_DESIGN.md (design system: shell, nav, tab-bar, tiles, board zoom/labels, HoldConfirm, banner rotator, result iconography) - ARCHITECTURE: app-shell + announcement channel (mock->server) + hint place-on-board / no_hint_available contract + board-style setting - FUNCTIONAL(+ru): hint-on-board, word-check constraints/throttle, board style - PLAN: Stage 7 -> done + polish refinement note; CLAUDE sources list	2026-06-03 13:38:17 +02:00
Ilia Denisov	7a48327ab6	Stage 7 (wip): docs bake + stage renumber (insert UI Stage 8, shift +1) ... - PLAN.md: new Stage 8 (UI social/account/history); Telegram->9, Admin->10, Linking->11, Polish->12; tracker + Stage 7 refinements; split the Stage 6 'wired in Stage 7' note between 7 and 8 - ARCHITECTURE: promote ui to current (slice scope, board-replay, codegen, theming, mock) - FUNCTIONAL(+ru): client-app section with the Stage 7/8 split - README + ui/README + CLAUDE.md: UI build/run/test, codegen, pnpm notes - bumped Stage 8-11 refs (+1) across docs and code comments	2026-06-03 01:01:58 +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
