Ilia Denisov	3306a016a0	feat(ui): per-kind active-game limit lock on the New Game screen ... Carry the caller's per-tier active-game caps and each game's kind on the wire (Profile.game_limits + GameView.kind, additive FBS + gateway transcode + client codec, committed regen). The New Game screen counts the player's active games per kind from the lobby and locks a capped start: an outline button with a lock that opens a funnel modal instead of a game -- a sign-in prompt for a guest, a "finish a current game first" notice for a signed-in account (native Telegram popup, in-app modal elsewhere). The lock lifts via the existing profile refetch after a guest->durable upgrade. Remove the lobby's old at_game_limit New-Game tab disable + notice: the flag (now the random-kind cap) conflicted with the per-kind lock -- it hid the screen where the lock lives and wrongly blocked an unfulfilled kind. The New Game tab is always enabled; the per-kind start lock is the only gate. The at_game_limit wire field stays (unused by the client) for a later cleanup. Tests: client lock logic + codec kind/game_limits roundtrip + gateway transcode encode + native popup builders (unit); a mock e2e for the lock badge and the modal.	2026-07-10 10:09:45 +02:00
Ilia Denisov	82648a4398	fix(game): show granted/bought hints in-game — finish the D31 wire removal ... The in-game hint badge ignored the payments hint wallet: loading a game clobbered app.profile.hintBalance with the deprecated StateView.wallet_balance (zeroed in the D31 domain removal but left in the protocol as a dead 0, then synced over the real balance at game load). Finish the removal honestly. StateView carries the per-game allowance alone (hints_remaining); the purchasable wallet lives solely on the profile and the client adds it (lib/hints). Removed StateView.wallet_balance across every layer — backend StateView/DTO, notify.PlayerState (live events), gateway StateResp + wire.StateView, the client model/codec/mock/localgame — and dropped the now-unused wallet arg from hintsRemaining. The FBS field is tombstoned `(deprecated)` (not deleted) so the vtable slots after it stay stable across a rolling deploy; no accessor is generated. HintResult keeps wallet_balance (the real post-spend payments balance the client adopts into the profile). The StateView type no longer has walletBalance, so the clobber cannot return without a compile error. Tests: hintsRemaining (2-arg); hints.hintsLeft (allowance + live wallet, no strip); the game state/hint integration (allowance-only HintsRemaining); gateway transcode; FBS regen.	2026-07-10 06:26:49 +02:00
Ilia Denisov	13be7c3d9a	feat(ads): VK post-move interstitial + retire deprecated hint_balance/paid_account ... Interstitial video after a confirmed play or a hint, VK-only, offline banner-only. The gate is client-mirrored: the backend puts the config cooldowns (global 5m / vs_ai 30m / hint 1m) and a suppressed flag (the no-ads / no_banner gate, same as the banner) on Profile.ads via adsFor; the client self-gates on a per-kind last-shown time in localStorage, with the VITE_ADS_STUB contour "ad fired" toast. Never fires after a pass, exchange or resign. maybeShowInterstitial + vkShowInterstitial; the codec and gateway transcode carry the ads block. Also retires the deprecated accounts.hint_balance / paid_account domain usage (expand-contract, code only — the columns stay for a later DROP so image rollback stays DB-safe): drop the Account fields and their scan, the dead account.SpendHint, account.GrantHints and the admin grant-hints action; the in-game hint display now comes wholly from the payments hint benefit. Banner eligibility and account merge no longer read the legacy flags. Tests: ads.test.ts (the client-mirrored gate), the codec ads round-trip, the gateway ads transcode test, and a profile ads-config integration test (cooldowns + suppressed under no-ads / no_banner). Docs: PAYMENTS §10 (+ru) interstitial, the decision amends, backend README, the plan.	2026-07-10 02:48:10 +02:00
Ilia Denisov	9acf6ab3b4	fix(payments): VK-iOS freeze is purchase-only; remove the rewarded diagnostic ... Testing the rewarded slice surfaced a contradiction: rewarded ads let a VK-iOS user earn vk chips, but the blanket VK-iOS "spend freeze" then blocked spending them (the wallet showed "5 (view-only)"). Apple's ToS forbids only BUYING in-app values on VK-iOS (money -> chips), not spending or earning them — so the freeze is corrected to purchase-only: vkFrozen() now gates only CreateOrder (the money-in step), not spendableSources (spending). VK-wallet chips — earned via rewarded ads or bought on the same account elsewhere (VK Android) — now spend on VK-iOS too. (Owner's ToS finding.) Also: the temporary contour diagnostic confirmed VK returns only {result:true} for a rewarded view (no token/signature) — client-attested is final, no hardening possible — so the diagnostic (the log and the diag wire field) is removed. Docs: PAYMENTS(+ru) VK-iOS freeze + D17 amend + PLAN E6. Tests updated (gate / wallet VK-iOS now spendable).	2026-07-10 01:27:26 +02:00
Ilia Denisov	dbd76d53e8	feat(ads): rewarded video (VK) — client-attested credit + daily/hourly caps ... The first ads slice: a voluntary rewarded video credits chips. VK Mini App ads (VKWebAppShowNativeAds) expose only a client-side watch result — no server-to-server verify — so the credit is client-attested, guarded by a server daily + hourly cap (config reward_daily_cap / reward_hourly_cap, default 50 / 10). The caps are both anti-abuse (bounding a forger who skips the ad and calls the endpoint directly) and an economic conversion lever (limiting free chips so a player who wants more buys). D29 amended to VK's reality. Backend: CreditReward (VK-only, order-less, idempotent on a client nonce, floored by the caps; payout from config rewarded_payout_chips, default 0 = off) + the wallet.reward edge op returning the updated wallet (reward_chips gates the "watch for chips" CTA). Additive migration (two config columns). Client: the ads-network abstraction (lib/ads.ts, VK impl) + the VK bridge (vkRewardedReady / vkShowRewarded) + the Wallet CTA + i18n. A contour test stub (VITE_ADS_STUB -> a toast instead of a real ad; prod always real) and a temporary diagnostic that logs the raw VK data, so we confirm on the contour exactly what VK returns (harden to signature-verify if it carries one). Tests: backend integration (credit, nonce idempotency, hourly cap, disabled, non-VK refusal) + codec unit (reward wire). Docs: PAYMENTS(+ru) §10, D29 amend, PLAN E6. Bundle: shared budget 30->31 (reward i18n strings).	2026-07-10 00:41:42 +02:00
Ilia Denisov	6e03ce0131	feat(payments): Telegram Stars payment rail ... Accept real money via Telegram Stars (XTR) — the third intake rail alongside Robokassa (direct) and VK Votes. Only the bot reaches Telegram, so the rail funnels through the reverse mTLS bot-link: - the gateway mints the invoice on a CreateInvoice command (the bot calls createInvoiceLink, XTR; the link goes to WebApp.openInvoice); - the bot gates each pre_checkout_query via a ValidatePreCheckout unary (the order must exist, be still creditable and not already paid — the reusable-invoice double-pay guard; the decline reason is localised to the order account's language); - a completed successful_payment is queued in a durable pure-Go SQLite outbox and forwarded via a ForwardPayment unary, credited once (idempotent on telegram_payment_charge_id, honours an expired order), re-driven on restart and every 30s. The rail is wired by TELEGRAM_STARS_OUTBOX_DIR (default /data) but stays inert until a chip pack carries an XTR price, so seeding a Stars price in the admin is the go-live. Tests: backend integration (order->forward->credit once, duplicate, pre_checkout gate) + bot outbox unit (idempotent, restart re-drive) + executor createInvoice. Docs: PAYMENTS(+ru) §9, ARCHITECTURE, the platform/telegram README, PLAN.	2026-07-09 21:35:29 +02:00
Ilia Denisov	3bb9f10fad	feat(payments): VK Votes payment rail ... Wire the VK Mini Apps ("голоса") rail end to end, reusing the intake engine. The wallet.order endpoint branches by rail: a VK context opens a pending order (provider vk) and returns its id, which the client passes to VKWebAppShowOrderBox. VK's two-phase payment callback is verified at the gateway with the app protected key (GATEWAY_VK_APP_SECRET) and proxied to a backend intake handler: get_item returns the ordered pack's title and vote price; a chargeable order_status_change credits the vk segment exactly once (the same Fund, idempotent on VK's own order id) and records a succeeded event, so the dispatcher push refreshes the wallet. Integration test for the VK order->credit path.	2026-07-09 19:27:57 +02:00
Ilia Denisov	3e0763463f	feat(gateway): VK payment callback signature verifier ... Add the vkpay package: verify a VK Mini Apps payment ("голоса") callback signature — MD5 (mandated by VK's payment protocol) of the sig-excluded parameters, sorted by name and concatenated key=value, with the app secret appended; case-insensitive over the hex digest. Unit-tested (valid / tampered / wrong-secret / missing). First piece of the VK rail; the two-phase callback handler, the VK order branch and the client bridge follow.	2026-07-09 18:56:00 +02:00
Ilia Denisov	3367cc2bf1	feat(payments): payment-event dispatcher + the provider-return UX ... Deliver payment_events to connected clients as an in-app wallet-refresh push: a background dispatcher drains undispatched events and publishes a KindNotification "payment" signal, marking each delivered; the client bumps a wallet-refresh counter the open Wallet screen watches, re-fetching in place. A return-focus refetch is the fallback. The Robokassa Success/Fail return now serves a self-closing page (the payment opens in a separate window) so the customer drops back into the live app instead of a cold start. Integration test for the event drain/mark queue.	2026-07-09 18:26:06 +02:00
Ilia Denisov	4f6c22d669	feat(gateway): the Robokassa /pay/ edge routes ... Add the public /pay/robokassa/result callback proxy (rate-limited; forwards the provider's form parameters to the backend intake, the single writer, and echoes its "OK<InvId>" back to Robokassa) and the /pay/robokassa/{success,fail} browser-return redirects into the app. Route /pay/* to the gateway in the contour Caddyfile so the callback reaches the edge, not the landing catch-all. The backend intake now returns the echo body as JSON for the gateway to relay.	2026-07-09 17:33:22 +02:00
Ilia Denisov	2a6dc5a304	feat(gateway): wire the wallet.order edge call for the direct rail ... Add the WalletOrderRequest / WalletOrderResponse FlatBuffers messages and the wallet.order Connect op: the gateway decodes the order request, forwards it to the backend POST /wallet/order and returns the created order id plus the provider launch URL the client opens. Regenerate the committed Go and TS FlatBuffers code.	2026-07-09 17:30:39 +02:00
Ilia Denisov	4aa6174968	feat(payments): wallet screen with balances, benefits and storefront ... Add the "Кошелёк" section to the settings hub: context-visible chip balances, active benefits (no-ads term/forever, hints) and a storefront of chip-priced values and money-priced chip packs. Guests have no wallet; the Google Play build hides the money purchases behind a RuStore stub; a web purchase that would draw VK/Telegram chips warns first. Add the catalog read path the storefront needs — a context-projected GET /api/v1/user/wallet/catalog (payments service + store, gateway op wallet.catalog, FBS Catalog/CatalogProduct/CatalogAtom, client decode) — plus the client leg for the existing wallet.get/buy ops. Value spends reuse the existing spend path; the chip-pack purchase (money order flow) arrives with payment intake, so its action is a disabled placeholder for now. Covered by Go unit (catalog projection) + integration (/wallet/catalog over Postgres), vitest (formatting, spendable selection, web-spend warning, GP flag, codec + gateway encode round-trips) and Playwright mock e2e (render, guest-hidden, GP stub, warning) on Chromium + WebKit.	2026-07-08 12:37:32 +02:00
Ilia Denisov	1c06d1d0d1	feat(payments): chip wallet, store-compliance gate and benefit application ... Stand up the internal chip/benefit mechanic behind the narrow payments interface: context-aware balances and benefits, an atomic chip spend, admin grants as zero-price value sales, the one-directional store-compliance gate (VK/TG same- origin only, web draws direct→vk→tg, VK-iOS frozen, untrusted fail-closed), and per-origin hint and no-ads application with term stacking. Reads are served from an in-process, account-keyed write-through cache (mirroring the suspension gate), so hot paths issue no query to the payments schema. Flip the online-game hint wallet and the ad-banner suppression from the deprecated accounts.hint_balance / paid_account columns to the payments benefit (a hint balance no longer suppresses the banner — only a no-ads benefit does), and fold chip segments and benefits by origin on account merge, inside the merge tx. Add the GET/POST /api/v1/user/wallet edge chain (REST → Connect → FlatBuffers) plus its codec unit test; no wallet UI yet. Bring the frozen owner decisions log into the repo at docs/PAYMENTS_DECISIONS_ru.md (it was untracked under .vscode) and reference it from PLAN.md; record the read-cache design and the present-sources interface in PLAN.md and docs/PAYMENTS.md (+ RU mirror).	2026-07-08 06:06:40 +02:00
Ilia Denisov	92633f935e	feat(payments): trusted platform signal on the session ... Record the execution platform (kind vk|telegram|direct + device subtype ios|android|web) on each session, captured at creation and carried gateway->backend as a trusted X-Platform header, so the upcoming store-compliance gate has an unforgeable execution context. - backend.sessions gains nullable platform_kind/platform_subtype columns (migration 00011, CHECK-constrained, jet regenerated); session.Platform captures them at mint, resolve returns them, middleware exposes platform(c). kind is derived from the establish endpoint, never a client field; the account-merge session mint inherits the caller's platform. - gateway derives the platform (VK subtype from the signed vk_platform via vkauth, Telegram/direct best-effort from the client) and injects X-Platform on every authenticated backend call through the request context. - ui submits a best-effort device subtype on the telegram/guest/email login requests (new FBS subtype field); VK is server-derived from the signed params. - an unattributed session is untrusted (view-only); VK/TG self-heal on the next cold-start re-mint, direct/email on re-login. Signal plumbing only, no user-visible change; X-Platform is inert until the gate consumes it.	2026-07-08 03:31:51 +02:00
Ilia Denisov	7fc1301b31	feat(hint): unify the vs_ai idle hint online + offline (server-enforced, monotonic) ... Online vs_ai hints were broken: #207 made the vs_ai hint button always-enabled and wallet-free (assuming all vs_ai = the offline idle-gate), but the backend still served online vs_ai from the allowance/wallet, so over-clicking hit ErrNoHintsLeft -> a generic error toast. Now online vs_ai uses the SAME idle-gate model as offline. Backend: Hint() for a vs_ai game skips the allowance/wallet and increments no hints_used (owner: vs_ai counts toward no hint statistic), and is idle-gated from the SERVER clock -- it returns ErrHintLocked (code hint_locked) until the robot's last move + 30 min, else serves the top move. GameState/StateView expose hint_unlock_left_seconds (server-computed seconds remaining; 0 for a human game / first move / not-your-turn). Pure helper hintUnlockLeftSeconds unit-tested. Wire: StateView gains hint_unlock_left_seconds (FlatBuffers, additive); pkg/wire + gateway transcode carry it (round-trip test). Client: the gate counts down from a MONOTONIC clock (performance.now()) anchored to the source's seconds-left when it lands (on load from the view; to the full window when the robot moves), so a client clock change cannot skew it and a relaunch re-reads a fresh value. The vs_ai hint button (online + offline) shows the lock + toast; doHint handles the hint_locked backstop by re-syncing. Replaces #207's absolute hintUnlockAtMs on the wire/model/delta (the offline record keeps the absolute for persistence; the view exposes seconds-left). Docs FUNCTIONAL(+_ru)/ARCHITECTURE updated. Verified: go build/vet + game/server/transcode tests (+ new hintUnlockLeftSeconds); ui check 0 / unit 490 / e2e 198 (one pre-existing webkit offline flake) / app entry 114.2/115.	2026-07-07 00:42:43 +02:00
Ilia Denisov	020742fad3	fix(pwa): network-first navigation so a new deploy loads online immediately ... The C1 service worker served the precached shell for every navigation, even online, so a new deploy only reached a client after the worker updated its precache in the background (a one-launch lag): a cold online start showed the old version until then, and only a reinstall forced it fresh. - sw.ts: navigations are now network-first — fetch the fresh (no-cache) shell from the server on each online launch (it references the new hashed assets, fetched fresh), with a 3s timeout falling back to the precached shell when the network is unreachable or too slow. Only the tiny HTML is re-fetched; the immutable hashed assets stay cache-first and re-download only when their hash (the version) changes. Offline cold-launch still works via the fallback. - webui.go: serve sw.js with Cache-Control: no-cache so the browser reliably detects a new deploy's worker (regression-tested). Online launch is contour-verified (the mock e2e disables the SW); e2e 196. No new deps — the network-first handler is hand-written (~12 lines).	2026-07-06 16:45:07 +02:00
Ilia Denisov	1a95a5f2cb	feat(offline): app-shell precache service worker (vite-plugin-pwa) ... Migrate the former install-only public/sw.js to a custom (injectManifest) service worker built from ui/src/sw.ts by vite-plugin-pwa. It precaches the app shell + hashed assets (Workbox) so an installed web PWA cold-launches with no network, and falls in-scope navigations back to the precached shell (the hash router resolves the route client-side). This is the C1 prerequisite for a usable offline mode: without it a cold offline launch cannot load the bundle. - ui/src/sw.ts: skipWaiting + clientsClaim + cleanupOutdatedCaches + precacheAndRoute(__WB_MANIFEST) + a NavigationRoute fallback to index.html, deny-listing the RPC path and /_gm. The Connect stream and API POSTs are never precached nor intercepted. - vite.config.ts: VitePWA(injectManifest); manifest:false (we ship our own), injectRegister:false (registration stays manual + web-only in pwa.svelte.ts), disabled in the mock build (Playwright unperturbed); landing + polyfills excluded from the precache. - Removed public/sw.js; the registration path (dist/sw.js at /app/) is unchanged. - New dev deps: vite-plugin-pwa + workbox-{core,precaching,routing}. Docs: ARCHITECTURE + gateway/README. Offline cold-launch is contour-verified (the mock e2e harness disables the SW).	2026-07-06 11:06:59 +02:00
Ilia Denisov	a692024b4e	feat(profile): advertise per-variant dictionary versions for offline preload ... The Profile now carries dict_versions (game variant -> current dictionary version), populated from the dictionary registry at the profileResponse choke point, so an installed PWA can preload the matching dawg per enabled variant off the existing cold-start profile request instead of adding a round-trip for a rare feature. Wire path: FBS DictVersion table + Profile.dict_versions (additive, backward-compatible trailing field) -> backend dto/registry -> gateway ProfileResp + FBS encoder -> client codec decode into a per-variant map on model.Profile. Empty in a degenerate no-dictionary deployment; the mock serves v1.3.0 for all three variants. Codec decode covered by a bite-tested round-trip unit test.	2026-07-06 10:39:29 +02:00
Ilia Denisov	00bb66ba0f	fix(metrics): second-scale buckets for edge_request_duration ... The edge request-latency histogram records seconds but used the OTel SDK's default millisecond-calibrated bucket boundaries (first boundary 5), so every sub-5s request fell into one bucket and histogram_quantile(0.99) interpolated to ~4.95s for every message type — regardless of the real (millisecond) latency. That tripped the >1s "Gateway request latency p99 high" alert on essentially every request, flapping fire/resolve on each app open (seen on the test and prod contours). Set explicit second-scale bucket boundaries (0.005 … 10s) straddling the 1s SLO so the p99 reflects real latency and the alert fires only on genuine slowness. Regression test asserts the histogram carries a sub-second boundary.	2026-07-05 22:49:04 +02:00
Ilia Denisov	061366da5a	feat(email): PWA login sends code only; drop admin link from alert emails ... Two email changes, per the owner: 1. Code-only login from an installed PWA. A login requested while running as a standalone PWA now omits the one-tap confirm link from the email — the link would open in a separate browser whose minted session cannot reach the PWA, stranding the login. The code is typed in the same window instead. The client sends a `pwa` flag (isStandalone) on the email-code request (a new FBS field, threaded through the gateway); the backend omits the deeplink when it is set, reusing the existing deletion-code link-omission path. Non-PWA browser logins keep the one-tap link. No polling, no migration. 2. Security: the operator alert digest no longer embeds the admin-console (/_gm) URL. An admin link must never travel in an email, where a mail provider could cache or index it; the operator opens the console directly. Tests: an inttest asserting the PWA login email omits the link (and a browser one keeps it); a codec round-trip of the new pwa field; the alert-digest test flipped to guard the admin link is absent. Docs: ARCHITECTURE + FUNCTIONAL (+ru).	2026-07-05 22:13:21 +02:00
Ilia Denisov	51147a1429	feat(pwa): installable web app + landing web entry ... Make the web SPA an installable PWA and surface it to users: - manifest.webmanifest + an install-only service worker + 192/512/maskable icons (ui/public); PWA head tags in index.html; the .webmanifest MIME type registered in the gateway (the distroless image has no /etc/mime.types). - Platform-adaptive install CTA (components/InstallApp.svelte + lib/pwa): one-tap on Chromium, manual Add-to-Home-Screen instructions on iOS Safari, hidden elsewhere / once installed / inside a Mini App. Shown under the logged-out login card and at the bottom of Settings. - The landing gains a third entry linking /app/ (the brand tile), with a caption under all three (Telegram / VK / Веб-версия). The service worker is navigation-only (network-first, cached-shell fallback); hashed assets and the Connect stream are untouched. It exists to satisfy Chromium's installability requirement and is the single growth point for a future opt-in offline mode. Tests: pwa.ts unit tests; a webui probe (manifest/sw.js content-type + the SPA-fallback-to-HTML trap); e2e for the one-tap CTA, the iOS instructions modal and the landing web entry. Docs: ARCHITECTURE §13, FUNCTIONAL (+ru), gateway README.	2026-07-05 21:11:41 +02:00
Ilia Denisov	6db9178449	feat(banner): per-campaign colour overrides and urgent alerts ... Non-default campaigns gain an optional colour override (background / text / link) in two sets — one for every theme, one for the dark theme only — and an "urgent" flag. - Colours ride profile.get as six trailing FlatBuffers strings on BannerCampaign (backward-compatible). The client resolves the cascade (dark <- dark ?? all, light <- all) per rendered theme and derives the strip border from the background in JS (no CSS color-mix, for the old Android WebView floor); AdBanner applies them as inline vars scoped to the strip. - Urgent is resolved entirely server-side: while any enabled, in-window urgent campaign exists, computeActiveSet returns only the urgent campaigns and bannerFor skips the eligibility gate — so a system notice reaches every viewer (paid / hint-holding / no_banner included) and preempts the ordinary feed. No wire field; it appears on each viewer's next profile.get. - Admin console (/_gm/banners): native colour pickers + a live light/dark preview of the strip, and an urgent toggle. The default campaign stays plain, enforced by the service and a DB CHECK. Migration 00009 is additive (nullable colour columns + a bool default + all-or-nothing / hex / default-plain CHECKs) — expand-contract, rollback-safe. Docs: ARCHITECTURE §10, UI_DESIGN, FUNCTIONAL (+ru). Tests: ads unit (urgent preempt + colour validation), codec + resolver unit, gateway transcode, and integration (colour round-trip + urgent bypass against real Postgres).	2026-07-05 15:36:35 +02:00
Ilia Denisov	2feb638329	feat(gateway): unsupported-engine telemetry beacon + Grafana counter ... The index.html boot guard now fires a fire-and-forget beacon (POST /telemetry/unsupported) when it turns a client away on the unsupported-engine screen, so the owner can see — on the Users dashboard beside "app opens" — how many real clients hit it and on which engines. - Client: navigator.sendBeacon (fetch fallback) with a localStorage dedup keyed by app version + reason + Chromium, so a user reopening the app is one report, not ten. - Gateway: a new unauthenticated POST /telemetry/unsupported handler (the client never booted, so it carries no session), per-IP public-limited and body-capped, mirroring the export-download route. It folds the beacon into the OTel counter unsupported_engine_total {reason = no_bigint/no_proxy/boot_error/other, chromium}, with reason allow-listed and the Chromium major reduced to a bounded range (normalizeUnsupported) so a spoofed beacon cannot inflate the metric cardinality; the full user agent is logged, not labelled. - Caddy: /telemetry/* added to the @gateway matcher (else it falls to the landing catch-all). - Grafana: two panels on the Scrabble — Users dashboard (by reason, by Chromium major). - Docs: ARCHITECTURE.md §11. Tests: recordUnsupportedEngine (metric split), normalizeUnsupported (cardinality bounding), and the handler route end to end (204 / 405 / counter). go build+vet+test and gofmt clean; ui check/build/e2e green; the client beacon + dedup verified against a forced hard-gate (BigInt removed) — one POST, deduped on reopen, correct reason/chromium/version labels.	2026-07-04 23:03:47 +02:00
Ilia Denisov	2c465c01d2	feat(account): VK ID web login to link a VK identity from a browser ... A browser has no signed VK Mini App launch params, so linking VK on the web uses VK ID's raw OAuth 2.1 flow (PKCE, no @vkid/sdk): the SPA redirects to VK's hosted login and returns with an authorization code, which the gateway exchanges server-side (confidential, under the VK "Web" app's protected key) for the trusted vk user id — then the existing link/merge machinery attaches or merges it. - fbs LinkVKRequest{code, device_id, code_verifier}; codec + TS bindings. - backend link.Service ConfirmVK/MergeVK/attachVK (KindVK, mirror Telegram), handleLinkVK[Merge], routes /user/link/vk[/merge], backendclient LinkVK[Merge]. - gateway internal/vkid confidential code exchange (id.vk.com/oauth2/auth); transcode link.vk.confirm/merge (registered only when configured) + config GATEWAY_VK_ID_{APP_ID,CLIENT_SECRET,REDIRECT_URL} + main wiring. - UI lib/vkid (PKCE authorize redirect + callback), Profile "Link VK" control, boot callback handling; a merge re-authorizes for a fresh code (VK codes are single-use). Web-only (a redirect strands a Mini App webview). - Deploy: VITE_VK_APP_ID + VITE_VK_ID_REDIRECT_URL build args + gateway env, ci.yaml/prod-deploy TEST_/PROD_ vars, compose/Dockerfile/.env.example/README. - Tests: vkid exchange unit (string/number user_id, id_token fallback, errors), transcode link.vk, backend ConfirmVK/MergeVK inttest, codec encodeLinkVK. - Docs: ARCHITECTURE §4, FUNCTIONAL(+ru), gateway README.	2026-07-03 17:59:33 +02:00
Ilia Denisov	aa2290b7b4	feat(account): deletion orchestration + step-up + gateway edge ... Step-up: email accounts confirm with a mailed code (purpose=delete, no deeplink — ConfirmByToken refuses a delete token so a stray click can't delete); platform-only accounts type a fixed phrase (anti-impulse). Endpoints /user/delete/{request,confirm}; the confirm orchestration resigns active games, drops all-robot games, tombstones + anonymizes the account (freeing its creds), and revokes its sessions — the tombstone is the point of no return, the rest best-effort. Gateway account.delete.{request,confirm} ops + fbs AccountDeleteConfirm/AccountDeleteRequestResult + branded ru/en delete email. Integration tests cover the step-up (code + no-email) and the orchestration pieces.	2026-07-03 13:10:34 +02:00
Ilia Denisov	b918217497	feat(account): unlink provider + change-email edges (backend + gateway) ... Unlink: POST /user/link/unlink (telegram|vk) via account.RemoveIdentity, refusing the last identity; email is never unlinked. New fbs LinkUnlinkRequest + gateway link.unlink op, returning the refreshed profile. Change-email: purposeChange confirm-codes (RequestChangeCode/ConfirmChange) that atomically replace the account's confirmed email (account.replaceEmailIdentity); a new address owned by another account is refused without disclosure, never merged. The one-tap deeplink handles purposeChange too. Reuses the LinkEmail* fbs tables; gateway link.email.change.{request,confirm} ops + backendclient methods; branded ru/en change-email copy.	2026-07-03 09:47:42 +02:00
Ilia Denisov	3a823ca7ef	feat(profile): carry linked identities in the profile (email, telegram, vk) ... Add email / telegram_linked / vk_linked to the Profile (fbs table + regenerated Go/TS bindings, gateway ProfileResp + encodeProfile, backend DTO, UI model + decode). They are filled outside the pure projection — Server.profileResponse now reads the account's identities (like the banner seam) — and will drive the profile's Add / Unlink / change-email controls.	2026-07-03 09:17:17 +02:00
Ilia Denisov	762155a55e	feat(gateway): confirmEmailLink RPC + language on the email request + profile event ... Add the confirm-link edge method (auth.email.confirm_link): a new EmailConfirmLinkRequest/Result fbs table, the transcode const + handler + encoder, and the backend-client call to the existing /sessions/email/confirm-link endpoint — it rides Execute under the existing service prefix, so no proto/Caddy change. Add a language field to EmailRequestRequest and forward it (the backend already seeds it). Add the NotifyProfile sub-kind + notify.ProfileChanged, published by the confirm-link handler on a successful link so an in-app session re-fetches its profile when the email was confirmed in another browser. Regenerated fbs bindings (Go + TS).	2026-07-03 04:22:09 +02:00
developer	d5fbaa3034	feat(export): server-rendered artifacts behind one signed download URL (#160) ... The finished-game export (GCG + a new PNG of the final position) is one signed, short-lived relative URL (game.export_url; HMAC-SHA256, 10-min TTL, BACKEND_EXPORT_SIGN_KEY) resolved against the client's own origin and delivered by the best affordance each platform has (five on-device review rounds): - TG Android/desktop: native showPopup chooser -> native downloadFile dialog (bridge-only chain, activation-safe). - TG iOS: app-modal chooser -> OS share sheet with the fetched file (a popup callback cannot supply the activation the sheet needs). - VK iOS: VKWebAppDownloadFile for both formats. - VK Android: the PNG opens in VK's native image viewer, the GCG copies to the clipboard (the VK Android downloader hangs on any download, Content-Length/Range notwithstanding). - VK desktop iframe / desktop browsers: plain anchor downloads. - Mobile browsers: the OS share sheet (fetch-then-share). - Legacy TG (< Bot API 8.0): app modal + GCG clipboard, no image option. The PNG is rasterized on demand by the new internal `renderer` sidecar (node:22-slim + skia-canvas + baked Liberation/Noto Color Emoji fonts) executing the SAME ui/src/lib/gameimage.ts the ui project unit-tests; the backend rebuilds the render payload from the journal + engine.AlphabetTable, and the device date locale, IANA time zone and localized non-play labels ride the signed URL. Nothing is stored — the artifact re-derives from the immutable journal on each GET. The gateway forwards /dl/* (caddy @gateway matcher extended) behind the per-IP public rate limiter and serves bytes via http.ServeContent. Deploy: renderer service in compose + prod overlay + rolling order + prod push list; TEST_/PROD_EXPORT_SIGN_KEY secrets; the sidecar smoke runs in the ui CI job. Docs: ARCHITECTURE, FUNCTIONAL(+_ru), UI_DESIGN, TESTING, deploy/README, renderer/README.	2026-07-02 21:58:07 +00:00
Ilia Denisov	5f574a765d	feat(landing): VK entry logo + restore the Telegram channel build-arg ... Add the VK Mini App logo next to the Telegram one on the landing hero, linked via the new VITE_VK_APP_LINK build-arg (full URL, wired through compose, CI and prod-deploy from TEST_/PROD_VITE_VK_APP_LINK). Also restore the landing's Telegram link itself: commit 57c778f collapsed the per-language vars to VITE_TELEGRAM_GAME_CHANNEL_NAME in compose/CI but left gateway/Dockerfile with the stale _EN/_RU ARGs and without the plain one, so the built bundle saw the var as undefined and dead-code-eliminated the whole channel-link branch — deployed landings (prod included) have shown no Telegram logo since.	2026-07-02 00:10:02 +02:00
Ilia Denisov	2e8fa83814	feat(telemetry): local move-preview adoption metrics (Phase 4) ... Measure uptake of the client-side local move-preview accelerator (§5) so adoption can be watched before defaulting it on: app cold starts, dictionary loads by result (fetched / cache_hit / miss) and move previews by path (local / network — the backend load shed). A small best-effort client beacon (POST /metrics/local-eval, session-gated) batches counter deltas and posts them on a 60s timer and when the app is backgrounded — never on the gameplay path: the in-app counters are plain in-memory increments, only the periodic flush touches the network and it is fire-and-forget. The gateway folds each batch into three OTel counters (local_eval_cold_start_total, local_eval_dict_load_total, local_eval_preview_total), clamped against a spoofed inflation. - gateway: counters + recordLocalEval + session-gated /metrics/local-eval handler - ui: localeval-metrics accumulator/beacon; hooks in the dict loader, in Game.recompute and in bootstrap (skipped under the mock harness) - caddy: route /metrics/* to the gateway - docs: ARCHITECTURE §11; Grafana "Scrabble — Users" dashboard panels	2026-07-01 23:31:49 +02:00
Ilia Denisov	5689f7f6a3	feat: on-device move preview (local eval) with network fallback ... Score and validate a tentative move on-device instead of a per-arrangement network round trip. The dawg reader and the validate/score/direction slice of the scrabble-solver engine are ported to TypeScript (ui/src/lib/dict), pinned byte-for-byte to the Go engine by a `conformance` CI job (full-dictionary reader parity plus a battery of plays across every variant and both cross-word rules, including the inferred orientation). The server stays authoritative — submit_play re-validates — so the local result is an advisory accelerator only. - backend: Registry.DictBytes + an authed GET /api/v1/user/dict/{variant}/{version} (immutable) streaming the pinned per-game dawg; caddy routes /dict to the gateway. - gateway: a session-gated /dict edge route proxying it; fetchDict on the transport. - client: the dictionary loads on game open (low priority so it never starves the game on a slow link; aborted at a 5s cap or when leaving the game), is cached in IndexedDB (best-effort, self-healing on a rejected blob) and reused across sessions; a warm-up overlay covers a cold load, then the network preview is the fallback; a bad-connection breaker stops warming after repeated misses; the move preview cancels its in-flight request when the tiles change. - parity generators backend/cmd/{dictgen,validategen} + gated Vitest suites, run in CI against the release dictionaries. A hidden debug readout lists the cached dictionaries + breaker state, and its reset clears the cache. - docs: ARCHITECTURE §5, TESTING, UI_DESIGN, FUNCTIONAL (+ru).	2026-07-01 22:58:40 +02:00
Ilia Denisov	65c194264c	feat(vk): embed the game as a VK Mini App ... Mirror the Telegram Mini App wrapper for VK: the SPA loads at a new /vk/ entry, authenticates from VK's signed launch parameters, and provisions a 'vk' platform identity — the minimum to run the game in VK test mode. - Gateway verifies the launch signature in-process (internal/vkauth: HMAC-SHA256 over the sorted vk_* params under GATEWAY_VK_APP_SECRET, base64url) — a pure offline check, no side-service. New auth.vk op (gated on the secret), backendclient.VKAuth, /vk/ SPA mount. - Backend: KindVK + ProvisionVK/vkSeed, /sessions/vk handler, identity kind widened to include 'vk' (migration 00005, expand-contract). - UI: src/lib/vk.ts (VK Bridge, lazy-imported), bootVK + the /vk/ boot dispatch, encodeVKLogin + authVK across transport/client/mock. VK omits the name from the signed params, so the client reads it via VKWebAppGetUserInfo as an unsigned display seed. - Deploy: /vk in the edge Caddyfile, GATEWAY_VK_APP_SECRET wired through compose + .env.example + CI (TEST_) + prod-deploy (PROD_). - Admin console: surface the VK user id (link to the VK profile) next to the Telegram id on the user card. - Docs: ARCHITECTURE §12/§13, FUNCTIONAL (+ _ru), gateway README; VK integration reference under .claude/. Signature algorithm verified against dev.vk.com plus independent Node/Python references and a %2C edge-case vector.	2026-06-27 11:37:31 +02:00
Ilia Denisov	03dfc29a54	feat(telegram): promo deep-link seeds English Scrabble for new users ... The promo bot button carries a configurable variant-seed start-param (default verudit_ru-scrabble_en). The gateway parses start_param from the validated initData and forwards it; the backend, on first contact only, seeds the new account variant_preferences from it (English Scrabble alongside the default Erudit). No schema change (the scrabble_en CHECK is already in the baseline) and the gateway<->backend REST field is additive, so the rolling deploy is safe in either order. TELEGRAM_PROMO_START_PARAM configures the payload (empty forwards the user own /start payload). Covered by account unit tests, a gateway transcode test, and an integration test asserting new-only seeding.	2026-06-23 21:51:52 +02:00
Ilia Denisov	ef2c2d1eb9	feat(account): seed the time zone from the client's detected offset at creation ... A new account's time_zone defaulted to 'UTC' until the player saved a profile, so the robot's sleep window and the turn-timeout away-window sweeper — both anchored to the account zone via account.ResolveZone — ran on UTC for every fresh player, skewing robot-game timing until a manual Settings save. Seed the zone at creation instead, from the client's detected "±HH:MM" offset. - Carry browser_tz on the three account-creating auth requests (TelegramLoginRequest, GuestLoginRequest, EmailRequestRequest — the email account is provisioned at the code-request step, not at login) through the fbs envelope (+ Go/TS codegen), the gateway transcode + backend client, and the backend auth handlers into ProvisionTelegram / ProvisionGuest / ProvisionEmail. - create() now writes time_zone explicitly: the validated detected offset, or 'UTC' (equal to the column default) when absent or malformed — deterministic, never guessed. The column is already NOT NULL DEFAULT 'UTC', so no migration is needed and existing accounts keep 'UTC'. An existing account is never overwritten on re-login. - A detected zero offset is stored as "+00:00" (the zone is known and equals UTC), distinct from the "UTC" default that means "unknown" — which the feedback console's three-zone Filed display already reflects. - Guard the guest handler against an empty payload (the bootstrap historically carried none) so it degrades to no-seed rather than panicking in GetRootAs*. - Tests: zone seeding across Telegram/guest/email plus the "+00:00"/malformed/empty cases and the not-overwrite rule; codec round-trip for the three auth encoders. ARCHITECTURE + FUNCTIONAL(+ru) updated.	2026-06-22 18:43:24 +02:00
Ilia Denisov	004aca4e97	feat(feedback): capture the browser UTC offset; Filed time in three zones ... The account time zone defaults to UTC until a player saves a profile, so a report's Filed time could only render in UTC even for a player clearly in another zone. Capture the client's detected "±HH:MM" offset (browser_tz) with each submission and show the Filed time in three zones in the operator console — UTC, the browser offset detected at submit, and the sender's saved profile zone — each shown "N/A" when not known, so the operator can tell what is certainly known from what is merely defaulted. - Thread browser_tz through the fbs envelope (+ Go/TS codegen), the gateway transcode + backend client, and the backend feedback service/store; add the column via migration 00004 (additive, image-rollback-safe). - Fix fmtTimeIn to resolve "±HH:MM" offsets via account.ResolveZone; time.LoadLocation alone silently fell back to UTC for offset zones, which is the second reason a "+02:00" sender showed only UTC. - Update ARCHITECTURE/FUNCTIONAL(+ru) docs and the feedback integration test.	2026-06-22 18:05:39 +02:00
Ilia Denisov	b78ce42922	feat(feedback): capture the app version; show version + local Filed time ... Each feedback submission now carries the client app version (__APP_VERSION__), snapshotted like the interface language: FlatBuffers FeedbackSubmitRequest gains a version field → gateway transcode → backend, persisted in a new nullable feedback_messages.app_version column (migration 00003, additive so an image rollback stays DB-safe). The operator console detail shows the app version and renders the Filed time in UTC plus the sender's time zone (fmtTimeIn). Touches: fbs schema + regenerated Go/TS codegen, codec + transport (the client attaches its build), gateway transcode + backendclient, feedback store/service, admin view + template, docs (ARCHITECTURE §15, FUNCTIONAL + _ru). Verified: feedback integration tests (migration + version round-trip), codec round-trip, check/unit/build green.	2026-06-22 17:02:05 +02:00
Ilia Denisov	8d45ae6e3b	feat: stamp the build version into every service ... pkg/version.Version (default "dev") is set at link time via -ldflags from each service Dockerfile's VERSION build-arg, which the deploy passes as the git tag (git describe --tags). It surfaces as the OpenTelemetry service.version resource attribute (so Grafana/Tempo are version-aware), alongside the SPA's existing About version. Adds the VERSION build-arg to the backend/gateway/validator/bot compose builds and a serviceResource test covering service.name + service.version.	2026-06-22 07:28:27 +02:00
Ilia Denisov	e2771826fd	perf(gateway): pool backend conns; loadtest evaluate hot path ... The loadtest harness never modelled game.evaluate — the debounced per-tile play preview a real client fires several times per turn, the hottest gameplay call. Model it (one evaluate per placed tile + reconsideration re-previews + draft.save, human-paced; --eval / --eval-recon toggle it). That realistic load surfaced the real bottleneck: the gateway's backend HTTP client used the default transport (MaxIdleConnsPerHost=2), so every sync call to the single backend host churned a fresh TCP connection — ~26500 TIME_WAIT sockets at 500 players (near the ephemeral-port ceiling), burning ~1.75 gateway cores while the backend sat near-idle. It was the unfixed root of the residual transport_error the earlier passes chased on the client side. Widen the keep-alive pool (backendMaxIdleConns=512, ~2x the observed 225-conn peak). At 500 players the churn collapses to ~0 and peak gateway CPU drops ~7x (~1.75 -> ~0.26 cores); postgres (~1.65 cores) becomes the busiest service. This overturns the earlier "gateway is the binding constraint, scale it horizontally" sizing — that was sizing around this bug, not a real floor. Consolidate the loadtest trip reports into one loadtest/REPORT.md (drop the R2/R7 split) and bake the finding into README / PRERELEASE / ARCHITECTURE / TESTING.	2026-06-21 19:55:57 +02:00
Ilia Denisov	e71e40eef5	feat(telegram): promo bot + channel-chat moderation gate ... Add a second standalone promo bot to the bot container (answers /start with a localized message + a URL button into the main bot's Mini App) and gate write access in a channel's linked discussion chat: grant on join when the Telegram user is registered and neither admin-suspended nor holding a new chat_muted role, and revoke/grant on the matching moderation change for a member currently in the chat. Eligibility (registered AND NOT suspended AND NOT chat_muted; the game suspension dominates) is resolved once in the backend and reached two ways: the bot's join-time unary ResolveChatEligibility over the existing mTLS bot-link, and a backend chat_access_changed event -> gateway -> ChatGate command (idempotent; a temporary-block-expiry sweeper may over-emit). The bot guards the block/unblock path with getChatMember, since bots cannot list members. A web_app button cannot open another bot's Mini App (it signs initData with the sending bot's token), so the promo button is a t.me ?startapp URL reusing the UI's VITE_TELEGRAM_LINK. The bot must be a chat admin with the restrict-members right and chat_member in its allowed updates. No schema change: chat_muted reuses the data-driven account_roles table.	2026-06-21 14:46:51 +02:00
Ilia Denisov	041106d623	feat(gateway): temporary IP ban (fail2ban) fed by rejections + honeypot/honeytoken ... Add a prod-only, in-memory IP ban enforced at the edge, fed by three signals: sustained rate-limiter rejections (the IP-keyed public/email/admin classes — the user class stays the backend soft-flag's concern), a honeypot decoy-path hit (the contour caddy tags decoys with X-Scrabble-Honeypot and routes them to the gateway), and a honeytoken (a planted bearer, GATEWAY_HONEYTOKEN). A banned IP is refused with 429 by the abuseGuard middleware before any work — covering the Connect edge, the live stream and the static SPA/landing the per-op limiter never gated. The ban is off by default: it keys by the real client IP the shared-NAT test contour does not expose, so a ban there would be self-inflicted; detection still logs in the contour, only the ban action is gated (GATEWAY_ABUSE_BAN_ENABLED). Rejection bans last GATEWAY_ABUSE_BAN_DURATION; tripwire/honeytoken hits are near-zero-false-positive and earn longer fixed bans. Each ban increments gateway_abuse_banned_total{reason}. Operators see and lift active bans on the admin console's Throttled page; the gateway syncs its active set to the backend every 30s (POST /api/v1/internal/bans/sync, backend/internal/banview) and applies the operator unbans the response returns. PRERELEASE phase AG. Docs baked into ARCHITECTURE / FUNCTIONAL (+ru) / both READMEs.	2026-06-21 08:54:20 +02:00
Ilia Denisov	6aeb529f13	feat(telegram): split connector into home validator + remote bot ... Move all Telegram egress off the main host. The single connector held the bot token, long-polled Telegram and answered the gateway/backend over the trusted internal network, so the whole component (including login validation) shared fate with its VPN sidecar. Split it into two binaries that share the token: - cmd/validator (home, no VPN): Mini App initData + Login Widget HMAC only, never calls the Bot API. The gateway dials it for Telegram auth, so game login is now independent of Telegram reachability. - cmd/bot (remote): Bot API long-poll + sendMessage, the only component reaching Telegram. It holds no inbound port — it dials the gateway over a new reverse mTLS bot-link (pkg/proto/botlink/v1) and executes the send commands the gateway pushes. The gateway funnels sends to the bot-link: out-of-app push is fire-and-forget (at-most-once, dropped if no bot is connected); the backend admin broadcasts reach a gateway-served relay that forwards them and awaits the bot's ack (SendToUser/SendToGameChannel contract preserved). mTLS (pkg/mtls) is the one inter-service link that leaves the trusted segment; validator<->gateway and the relay stay plaintext internal. The bot is Telegram-rate-limited. One bot now; the gateway bot registry, an owns_updates flag and per-command ids leave seams for N later. Webhook rejected (one URL per token, adds inbound + a static address). The unified test contour runs the split (the bot keeps its VPN sidecar and dials the gateway by its internal name; bot-link certs from deploy/gen-certs.sh, generated in CI). The prod wiring — the bot on a separate host (no VPN), the gateway bot-link port published, PROD_ certs with scheduled rotation, an SSH deploy of both hosts together — is the deferred final stage (PRERELEASE.md TX, Stage 18). Docs: ARCHITECTURE, PRERELEASE (phase TX), platform/telegram + gateway + backend + deploy READMEs, FUNCTIONAL(+ru), CLAUDE.md, .env.example.	2026-06-21 00:19:07 +02:00
Ilia Denisov	57c778f9b2	feat(telegram,game): single bot + per-user variant preferences ... Collapse the two per-language Telegram bots into one unified bot and replace language-based variant gating with explicit per-user variant preferences. - Telegram: one bot; drop service_language and the supported_languages set everywhere (DB, account, auth, FlatBuffers Session wire, gateway, connector proto). The single bot renders chat and out-of-app push in the recipient's preferred_language; remove the game-language push routing override (notify Intent.Language / push Event.language). - Preferences: new accounts.variant_preferences (text[], DB default {erudit_ru}, CHECK non-empty + subset of the three variants). Gates the New Game picker, vs-AI and the friend invitation the player creates, enforced server-side (HTTP 400 otherwise); an invited friend may still accept any variant. Edited on the Settings screen; variants are Erudit-first everywhere. - Admin: drop the per-bot language selectors (broadcast / send-to-user) and the feedback channel_lang column/field. - Env/CI: collapse TELEGRAM_BOT_TOKEN_{EN,RU}, TELEGRAM_GAME_CHANNEL_ID_{EN,RU}, VITE_TELEGRAM_LINK{,_EN,_RU} and VITE_TELEGRAM_GAME_CHANNEL_NAME_{EN,RU} to single unsuffixed names; drop GATEWAY_DEFAULT_SUPPORTED_LANGUAGES. - Docs updated (ARCHITECTURE, FUNCTIONAL + _ru, platform/telegram, gateway, backend, ui, UI_DESIGN, PRERELEASE). The migration squash is deferred to a follow-up PR.	2026-06-20 14:23:25 +02:00
Ilia Denisov	c127bc9f0e	feat(social): per-game friend request to disguised robots + lobby/stats/tile cosmetics ... Functional: the in-game add-friend handshake aimed at an auto-match opponent who is secretly a pooled robot now records the request per (game, seat) in a new robot_friend_requests table -- never against the shared robot account -- mirroring the robot_blocks pattern. The shared account stays out of friendships, the "requested" state is pinned to the seat (not leaked across the player's other games), the robot ignores it, and a background reaper drops the row 7 days after its game finishes. The outgoing-requests list carries these per-game rows so the seat control stays disabled across reloads. No withdraw UI, per owner decision. Cosmetics: - Lobby: an in-progress game tints the viewer's own score number green when leading or tied, red when trailing (reusing --ok/--danger); scores now render in seat-number order, matching the over-the-board scoreboard. - Stats: the per-variant best move is laid out on two lines -- the variant label, then the score (right-aligned in its column) and the word tiles (left-aligned) below it. - Dark theme: the played-tile background is a touch darker so a player-placed tile reads with more contrast (light theme unchanged). Docs (ARCHITECTURE, FUNCTIONAL + _ru mirror, backend README, UI_DESIGN) updated in the same change.	2026-06-19 21:39:27 +02:00
Ilia Denisov	6e77de4c1e	feat: sparser robot nudges, typed unread badge, lobby unread bump ... Three owner-requested polish changes: - robot: replace the lengthening 60-90 min -> 6 h proactive-nudge ramp with a flat uniform 9-12 h wait before every nudge; the existing sleep-window gate still skips and defers a nudge that would land in the robot's night. - ui: colour the lobby/in-game unread dot by type -- the regular danger colour when a chat message is unread, a softer amber (--warn) when only nudges are. Adds a per-viewer unread_messages flag (chat_messages.kind='message') across the backend DTO, FlatBuffers wire, gateway transcode and the UI store. - ui: float games with any unread notification to the top of the lobby's your-turn and opponent-turn sections (finished keeps its order), reusing the existing unread_chat flag. Docs (ARCHITECTURE 7, FUNCTIONAL + _ru) updated. No DB migration; the new wire field is backward-compatible.	2026-06-19 16:50:48 +02:00
Ilia Denisov	64be0572b3	fix(social): robot blocks ... Blocking an auto-match opponent who is secretly a pooled robot is recorded instead in a separate `robot_blocks` table. Now blocking behaves the same in that game (struck name, hidden composer) and lists the blocked opponent under the name you saw, but is recorded only against that game — the disguise holds, the shared robot is never globally blocked, and the matchmaker keeps pairing you with robots (so you can never block yourself out of opponents). - the shared robot account is never put in `blocks` - the matchmaker keeps it free and it is not blocked under its other per-game names - the blocked list and the in-game card still show it by joining that table; an unblock deletes the row	2026-06-18 13:12:19 +02:00
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	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	0946a3f66c	feat(ads): server-driven ad-banner backend, wire & admin console (PR1) ... Turn the gated-off mock banner into a real advertising subsystem (backend + admin half; the UI rotation lands in PR2). - internal/ads: campaigns (percent weight + validity window; a perpetual, undeletable default that fills the remainder up to 100%), 1..N bilingual messages (en+ru), global display timings; ActiveSet computes the window-filtered, default-remainder, GCD-reduced, language-resolved rotation feed. Smooth-weighted-round-robin math is unit-tested. - migration 00006 (+ jetgen): ad_campaigns / ad_messages / ad_settings, seeded default campaign + house message + default timings. - eligibility = !paid_account && hint_balance==0 && !no_banner role (new role; guests qualify). The resolved feed rides the profile.get response (no new RPC, works for guests, nothing distinct to filter); language by service_language. - live update: a notify `banner` sub-kind (re-poll signal) published when an operator grants hints or grants/revokes no_banner, so the client shows/hides in place. - admin console /_gm/banners (+ /_gm/banner-settings): campaign + message CRUD with reorder, default protection, clamped timings. - wire: fbs BannerInfo/BannerCampaign on Profile; gateway transcode forwards it. - docs: ARCHITECTURE §10, FUNCTIONAL (+ _ru), backend README, PRERELEASE tracker (incl. the deferred app.load aggregator note).	2026-06-15 23:00:19 +02:00
