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	1e087be90a	fix(offline): hotseat finished-game medals by final score (fix all-last-place on a tie) ... Reported: a hotseat game ended by 6 scoreless passes deducts each rack (correct rule, same as online: -8/-14/-8 here), which tied two seats for the lead. The engine's winner() returns -1 on a tie, so seatMedal read it as a full draw and gave EVERY seat the last-place medal. - result.ts: seatMedal now ranks by the FINAL score (competition ranking — a tie for the lead shares the trophy), not the single-winner flag. A resigned / host-excluded seat places last with no medal and does not push the others down. - model.ts: Seat.resigned (offline-only); engine.resignedOf getter; the local source surfaces it on the game view. - The scoreless rack deduction is unchanged (standard rules, owner-confirmed).	2026-07-07 15:37:25 +02:00
Ilia Denisov	beda6ccd3d	fix(ui): iOS soft-keyboard shell alignment + hotseat relock on return ... iOS Safari/WKWebView does not shrink the layout viewport for the soft keyboard (Android Chrome does): the visual viewport shrinks AND offsets down toward the focused field, and the values do not cleanly revert. The pinned shell tracked only the height (--vvh), not the offset, so its top-anchored content misaligned on iOS — empty space below the form, worst on a repeat focus. Fix (one place; covers NewGame, Chat, Feedback): - app.svelte.ts syncViewport: also mirror visualViewport.offsetTop into --vv-top, and scroll the focused field into view on the keyboard-open transition (iOS does not reliably scroll a pinned document to it). - app.css: the pinned app-shell body follows top=--vv-top + height=--vvh (was inset:0), so it stays on the visible area. - e2e/viewport.spec.ts emulates the visual-viewport resize+offset (a fake window.visualViewport) to verify the shell follows, on Chromium+WebKit. Hotseat: returning to the lobby now re-locks the current seat (its PIN is re-prompted) — LocalSource.relock, cleared in Game.svelte onDestroy. Root-caused a crash it exposed: a $props() value (id) reads back undefined during Svelte teardown, so isLocalGameId(id) threw and aborted onDestroy (breaking navigation) — read the id from the loaded view instead.	2026-07-07 14:10:57 +02:00
Ilia Denisov	903de7d41d	fix(offline): unlock finished hotseat games + raise entry budget to 120 ... - source: a finished hotseat game is never locked (its final rack is shown for review, not an Unlock button); guard locked on !isOver. - bundle-size: raise the app-entry budget 115 -> 120 KB for the hotseat UI (PIN pad, roster, host menu), which lives in the always-loaded New Game / Game / Lobby screens; the offline engine + PIN hashing stay lazy.	2026-07-07 12:04:46 +02:00
Ilia Denisov	8c67d679d9	feat(offline): hotseat record schema + source (locks, host actions) ... Extend the local game to offline pass-and-play (hotseat): - serialize.ts: Seat.pin, record hotseat + hostPin (all optional; old vs_ai records read hotseat as false). - source.ts: create() takes hotseat/hostPin + per-seat pins; stateView reveals the seat-to-move's rack and withholds it (locked) when that seat is PIN-locked, until unlockSeat; ephemeral per-turn unlock re-locks on advance; new unlockSeat / verifyHostPin / hostAction (skip/resign/terminate); gameView sets vsAi=!hotseat + the hotseat flag. - model.ts: GameView.hotseat, StateView.locked (offline-only, optional). Tests: source.hotseat (lock/unlock/re-lock, host skip/resign/terminate, master-PIN gate, natural-end persistence) + serialize hotseat shape.	2026-07-07 11:20:39 +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	359af83c34	fix(offline): zero tile weights on cold boot + wrong-mode game in the lobby ... Two pre-existing offline bugs, both exposed once offline mode became usable (cold boot + toggling), owner-reported on the contour. Bug 1 -- offline tiles render weight 0. The rack/board read tile values from the lib/alphabet cache, populated only by the online wire codec (server-sent alphabet) or the mock (so the e2e masked it). A local game never goes through the codec, so on a cold offline boot with no prior online session the cache was empty and every value read 0 (scores stayed correct -- they come from the offline ruleset). Fix: the local source seeds lib/alphabet from the static offline ruleset (letters + values) when it builds a game view. Bug 2 -- the lobby showed (and could open) the other mode's game after a toggle. Two causes: (a) the lobby cache was not mode-tagged, so getLobby() instant-rendered the last snapshot regardless of mode; (b) load() wrote the module list after an await with no generation guard, so a slow online gamesList() finishing after a fast offline list() (or vice versa) left the wrong mode's games on screen. Fix: tag the snapshot with offline and gate getLobby() on it; add a load-sequence guard so only the latest load() writes. - localgame/source.ts: ensureAlphabet from the ruleset in gameView (+ unit test). - lobbycache.ts: LobbySnapshot.offline + getLobby(offline) mode check (+ tests). - Lobby.svelte: setLobby tags the mode; load() carries a generation guard. check 0 / unit 485 / e2e 198 / app entry 113.8/114.	2026-07-06 23:11:17 +02:00
Ilia Denisov	ff486c80f8	feat(hint): persist the vs_ai idle-hint wait (wall-clock + read sanitiser) ... Per the owner's call, the idle-hint gate now PERSISTS across leaving and reopening the app, instead of the session-scoped monotonic clock: the unlock is a wall-clock instant (hintUnlockAtMs) stamped from the robot's reply, stored on the local record, carried on the game view + the opponent_moved move delta, and read through a sanitiser that caps it at now + the window. So: - the wait survives a relaunch (a stuck turn is not forgotten); - a device clock set BACK cannot freeze the gate (the cap bounds the remaining to the window and self-heals on the next read); - a clock set FORWARD just opens the hint early -- accepted as harmless for a solo game. - lib/hints.ts hintGateRemainingMs now takes the unlock instant + clamps to the window. - localgame: re-add hintUnlockAtMs to the record/meta; stamp it off the robot's reply; sanitise on read (a shared hintUnlock helper feeds stateView + the opponent_moved event). - gamedelta + PushEvent: the move delta carries hintUnlockAtMs so the view stays fresh. - Game.svelte: hintUnlockAt derives from the view; the tick + lock + toast unchanged. - offline.spec.ts: also assert the lock survives a reload (the wait persisted). - Docs FUNCTIONAL(+_ru)/ARCHITECTURE updated (persist + sanitiser, not monotonic-resets).	2026-07-06 22:34:50 +02:00
Ilia Denisov	42a6308261	feat(hint): idle-gated wallet-free vs_ai hint on a monotonic clock (B4) ... A vs_ai hint is now unlimited and wallet-free, but idle-gated as an anti-frustration aid: it unlocks only after the player has been stuck ~30 min on a turn (timed from the robot's last move; the human's first move, before the robot has played, is exempt). While gated the hint button carries a small lock badge and a tap shows the remaining minutes ('Available in N min.'); the lock lifts live at the mark. The gate is enforced CLIENT-SIDE against a MONOTONIC clock (performance.now()), never a wall-clock timestamp: a device clock the player controls (or an auto-sync) must not be able to open or freeze it. The wait is therefore session-scoped -- a reload restarts it (there is no tamper-proof way to carry idle time across a relaunch without a wall clock). An online vs_ai game will gate the same way but from the server's clock (a follow-up). - lib/hints.ts: HINT_GATE_MS + pure hintGateRemainingMs (monotonic) + hintLockMinutes; removed the wall-clock hintRemainingMs. Unit-tested red->green. - Game.svelte: the monotonic gate (hintGateStart/monoNow, armed on the turn change), a vs_ai hint button (plain: no confirm, no count; lock badge + gated tap -> toast), a live 10s tick. - localgame: removed the wall-clock hint gate and the now-dead robotLastMoveAtUnix field from source.ts/serialize.ts (the client is authoritative); hint() just serves the top move. - i18n game.hintLockedIn. - offline.spec.ts: assert the first move is un-gated and the lock arms after the robot moves. - Docs FUNCTIONAL(+_ru) + ARCHITECTURE; bundle budget 114->115 (game-screen feature).	2026-07-06 22:03:27 +02:00
Ilia Denisov	e9f4cb0178	test(offline): mock e2e for a device-local vs_ai game (C8) ... A Playwright spec drives the whole offline flow in the mock build: force the installed-PWA display mode, enter offline via the Settings toggle (its readiness check fetches the dawgs), assert the blue chrome + online-games-hidden + Stats-disabled, then create and play a device-local English vs_ai game with a pinned bag seed (deterministic rack NEWYMAO) -- play the opening WAY across the centre, watch the robot reply with a real move, and reload to confirm the IndexedDB replay. Enabling infra (all e2e-only; nothing enters the production build): - mock/client.ts fetchDict serves the per-variant dawgs from the preview build's /e2edict/ (was: threw 'unsupported in mock'). - scripts/e2e-dict.mjs copies the real dawgs into dist-e2e from E2E_DICT_DIR (the ui CI job fetches the scrabble-dictionary release like the Go jobs; local default: the sibling scrabble-solver/dawg); playwright.config runs it between build and preview. - localgame/id.ts setForcedSeed + gateway.ts window.__mock.setLocalSeed: a mock-only seam to pin a local game's bag seed (tree-shaken from prod). - ci.yaml ui job: fetch the dawgs + pass E2E_DICT_DIR to the e2e step. - docs/TESTING.md: the offline e2e + the mock-dawg wiring. Verified: check 0 / unit 482 / e2e 198 (both engines) / app entry 113.8/114.	2026-07-06 20:54:03 +02:00
Ilia Denisov	3a72bc29ba	fix(offline): delete a finished local game from the device, not the network ... The lobby's finished-game delete (hide) always called gateway.hideGame; for a local (offline) game the transport kill switch refused it, so it toasted and the game stayed. Route by id: a local game is removed from the device store + the source cache (LocalSource.delete), an online game still hides on the backend.	2026-07-06 16:59:36 +02:00
Ilia Denisov	2a045a5b37	fix(offline): give the local human seat the real account id ... In a local game the human seat's account id was a synthetic 'local:human:0', so seatName's `accountId === session.userId` check never matched: the game header rendered BOTH seats as 🤖 (the vs_ai fallback), and the lobby's groupGames could not find the viewer's seat, so a human's turn read as 'Their turn' with the hourglass. Carry the real account id on the human seat (create -> record -> GameView); the robot keeps its synthetic id. Local games created before this fix keep the old display (no migration).	2026-07-06 15:36:51 +02:00
Ilia Denisov	ef832b823d	feat(offline): offline lobby lists + creates local vs_ai games ... In offline mode the lobby now shows only the device-local games and its New-vs-AI entry creates one through the in-browser engine — the visible payoff of the offline mode. - LocalSource.list() reconstructs a lobby GameView per stored local game by replay, exposed through the lazy gamesource proxy; unit-tested via an in-memory store. - Lobby.load() branches on offlineMode: lists local games and skips every gateway call (no online games/invitations/incoming); the Stats tab is disabled offline. - NewGame offline: find() creates a device-local vs_ai game via LocalSource.create using the profile's advertised dict version + a local seed; the friends flow and the random-opponent option are hidden, and the variant picker / Start are enabled offline (were gated on connection). - id.ts: newLocalGameId + randomSeed (tested). Docs: ARCHITECTURE + FUNCTIONAL(+ru) offline-mode section. Deferred to fast-follow: the Settings Friends/Profile/Feedback affordance gating, the flip-to-offline readiness wait, the offline mock e2e (needs mock-dawg support), and the local-hint UI. The offline flow is verified on the test contour — the mock e2e cannot enter offline mode (the toggle is gated to an installed PWA).	2026-07-06 11:35:23 +02:00
Ilia Denisov	1654131904	feat(offline): wire the local game source into the game screen (Phase B3.2) ... The game screen now drives a local vs_ai game through the offline engine, dispatched by game id — completing the playable local game (on top of the source, #193). Online play is unchanged. - gamesource.ts: gameSource(id) returns the local source for a `local:` id, else the gateway (the same game-loop interface). The offline engine stays OUT of the app entry bundle — it is dynamically imported on first use (a separate chunk), so online-only users never pay for it (the app entry stays within its size budget). - localgame/id.ts: the tiny id helper (no engine imports) the dispatcher branches on. - Game.svelte: the game-loop calls (state/history/submit/pass/exchange/resign/hint/ evaluate/draft) go through gameSource(id) instead of the gateway directly; a local game's robot-reply events route through the same app event hub the network stream feeds, so the screen reacts to opponent_moved / game_over identically. Behaviour-preserving for network games (gameSource returns the gateway for them). Local verify green: check + test:unit + build + bundle-size gate + e2e (196 passed).	2026-07-06 09:24:55 +02:00
Ilia Denisov	32298595f2	feat(offline): local game source (Phase B3.1) ... A GatewayClient-shaped facade over the offline engine, so the same game screen can drive a local vs_ai game with no backend (the wiring into Game.svelte is B3.2). - source.ts: LocalSource implements the game-loop subset (GameLoopSource) for a local game id — gameState/gameHistory via replay, submitPlay/pass/exchange/resign apply the human move then run the robot (decide(generateMoves)) synchronously, persisting both and delivering the robot's move through a per-game event emitter (no live stream). hint is gated to >30 min since the robot's last move; evaluate/checkWord are local. It translates the UI's glyph space to the engine's index space with the static letters table. - ruleset.ts: add the static per-variant letters (glyphs), pinned to the Go alphabet — offline is now fully self-contained (no reliance on a warm server alphabet cache). - engine.ts: submitPlay (infers the direction like the server SubmitPlay), evaluatePlay + dictionaryHas for the move preview / word check, and record the main-word coordinate + the words on a play (for the history MoveRecord). - source.test.ts: create -> human pass -> synchronous robot reply via the event, the hint gate, decoded history, and a whole game driven to completion. Pure additive library code; no runtime behavior change (bundle unchanged).	2026-07-06 09:07:40 +02:00
Ilia Denisov	4fa77bf82c	feat(offline): local game persistence + replay (Phase B2) ... Store an offline game durably and reconstruct it — the offline counterpart of the server's replay rehydration. Builds on the engine (#191); not wired into the UI yet (Phase B3). - serialize.ts: a LocalGameRecord (seed + rules + seat metadata + the alphabet-index move journal) and replayGame() — reconstruct a live LocalGame by seeding a fresh engine identically and replaying the journal. The board/bag/racks are not stored; they are deterministic from the seed and the replayed operations, so the record stays small. The journal is dictionary-independent (alphabet-index space, stable per variant). - store.ts: an IndexedDB store for local games (save/get/list/delete), mirroring lib/dict/store.ts — its own database, best-effort, guarded when IndexedDB is absent. - engine.ts: record the swapped tiles on an exchange (needed for exact replay) and expose the game's rule config. - serialize.test.ts: a round-trip — reconstruct a mid-game and a finished game by replay and assert the state (board/racks/bag/scores/turn/log) is identical. Pure additive library code; no runtime behavior change (bundle unchanged).	2026-07-06 08:22:47 +02:00
Ilia Denisov	e4cf143e9f	feat(offline): local game engine (Phase B1) ... The offline vs_ai game engine — a faithful TS port of backend/internal/engine that drives a whole local game with no backend. Composes with the move generator (#188) and robot strategy (#189) from Phase A; not yet wired into the UI (Phase B2/B3). - ui/src/lib/localgame/ruleset.ts: static per-variant tile values / bag counts / blank count, mirrored from rules.go (offline scoring is self-contained; online uses the server alphabet). Pinned by ruleset.parity.test.ts against a Go fixture. - bag.ts: the tile bag (fill from counts/blanks, draw-from-end, return+reshuffle) on a deterministic in-house PRNG — a game replays from its seed, not bit-identical to a server game (per plan). - board.ts: the mutable board, satisfying the validator/generator read view + set(). - engine.ts: LocalGame — deal / play (reusing validate.ts) / pass / exchange / resign, scoreless(6) & out-of-tiles end detection, end-of-game rack penalties, winner; mirrors game.go. The end-game math is exported as pure functions, pinned against the Go engine (engine.parity.test.ts, 9 constructed positions). - engine.test.ts: a full-loop smoke — two robots play a whole vs_ai game to completion via generateMoves + decide, and it is reproducible from the seed. - backend: movegen now dumps the per-variant rulesets; a new in-package engine emitter (endfixture_test.go, env-gated) produces the end-game golden. Pure additive library code; no runtime behavior change (unused at runtime, bundle unchanged).	2026-07-06 08:02:05 +02:00
