Ilia Denisov	2d1fadb50c	feat(offline): implicit net-state model, two-tier version gate, unified lobby ... Land the offline-model redesign (ANDROID_PLAN.md O1-O7): replace the explicit offline toggle with a single detected net-state machine, unify the lobby, and add a two-tier client-version gate. Contour-safe: both version vars empty => dormant, the wire change is additive, so web/pwa/vk/tg behaviour is unchanged unless the gate is deliberately configured. O1 net-state reducer (test-first). O2 store + wiring (connection/offline shims; +@capacitor/network). O3 remove the offline toggle + migrate the pref. O4 two-tier gate: hard update_required degrades to an offline Update/Play-offline notice (not terminal); soft GATEWAY_RECOMMENDED_CLIENT_VERSION -> X-Update-Recommended nudge. O5 unified lobby (device-local + greyed-from-cache server games; self-set identity; closes G-step-0). O6 create flows (with-friends online/offline segment + offline dict guard). O7 docs. Telegram/VK stay online-only (contour review): the offline model is channel-gated via offlineCapable() (native + plain web; false in the mini-apps). offlineMode.active is hard-gated on it, so the whole model (blue chrome, unified/greyed lobby, transport kill switch, device-local vs_ai/hotseat create) stays inert in Telegram/VK regardless of the detected net state (closing a version-lock path that could have flipped them offline); and New Game's with-friends hides the online/offline segment there, leaving the remote invite alone. ARCHITECTURE already declared "Telegram/VK are exempt" - this makes the code match. Deploy/CI: wire the version gate through the deploy (GATEWAY_MIN_CLIENT_VERSION + GATEWAY_RECOMMENDED_CLIENT_VERSION as plain unprefixed vars via compose + ci.yaml + prod-deploy.yaml + write-prod-env.sh + .env.example) so the gate is live when set (test-contour commit-hash version fails open; empty => dormant). Disable the manual android-build CI workflow for now (rename .disabled). Bump the app bundle budget 127->130 KB for the added always-loaded wiring. Fix the UI Docker stage (gateway/Dockerfile): install --ignore-scripts so the Alpine/musl SPA build no longer tries to native-build sharp (a local android:assets tool, unused in the image); esbuild's binary is an optional dep so Vite still builds. Tests: gateway go green (two-tier gate over a real HTTP handler); docker build of the landing + gateway targets green locally; compose --no-interpolate confirms the gateway env; two new telegram.spec.ts e2e (offline signal keeps the chrome online + quick-match opponent choice visible => server enqueue; with-friends shows no pass-and-play), RED-verified; svelte-check 0/0, vitest 617, e2e 248 (chromium + webkit), build + bundle-size 127.8/130.	2026-07-13 02:50:41 +02:00
Ilia Denisov	bcd5a1d02d	feat(ui): offline-first foundations — bundled dicts + local-guest identity ... The additive groundwork for the native offline-first experience (ANDROID_PLAN.md §D). Inert until the native cold-boot lands: on the web these paths never fire, so web / VK / Telegram behaviour is unchanged. - ui/scripts/bundle-dicts.mjs copies the scrabble-dictionary release DAWGs into dist/dict/<variant>@<version>.dawg for the native pipeline (run after `pnpm build`, before `cap sync`). - The dict loader gains a bundled tier between the IndexedDB and network tiers, attempted only on a native channel (a packaged app serves ./dict/<key>.dawg from its assets). Native-gated rather than the plan's "404 on the web" because the relative path would otherwise hit the gateway's own session-gated /dict/ route. - __DICT_VERSION__ Vite define (from VITE_DICT_VERSION, default "dev") + its ambient declaration; the offline vs_ai / hotseat creates in NewGame fall back to it when a device-local guest has no profile-advertised version. - New lib/localguest.ts: a persisted device-local guest id (no DB row); the offline vs_ai human seat uses it (and the localized common.guest name) when there is no server session. svelte-check clean, vitest green, native + web builds clean. The cold-boot rewrite, reconciliation, the Profile soft-sign-in gating and the offline-first e2e follow.	2026-07-12 16:41:19 +02:00
Ilia Denisov	30770a759b	feat(offline): gate the offline toggle on dictionary readiness ... Flipping the Settings toggle to offline now checks that every enabled variant's dictionary is on the device before entering offline mode: it fetches missing ones cache-first and waits up to ~5 s (raceOfflineReady + the lazy dict/offlineready), greying the toggle meanwhile. If they cannot be readied in time it stays online and shows a 'needs internet' note, while the fetch keeps warming the cache in the background so a later flip is instant. Leaving offline is never gated. Prevents entering a half-baked offline mode (no dawg -> cannot create/play a local game) when the background preload has not finished (poor connection, or an immediate flip right after install). - offline.ts: raceOfflineReady (pure, injected sleep; unit-tested red->green) - dict/offlineready.ts: ensureOfflineDicts (cache-first preloadDicts, lazy chunk) - offline.svelte.ts: requestOffline + TOGGLE_READY_BUDGET_MS - Settings.svelte: checking/needsData state, disabled toggle, inline note - i18n: settings.offlineChecking / settings.offlineNeedsData (en+ru) - docs: FUNCTIONAL(+_ru) offline story + ARCHITECTURE offline paragraph	2026-07-06 20:03:12 +02:00
Ilia Denisov	2f867b8e6c	feat(offline): background-preload dictionaries for offline readiness ... An installed PWA (standalone web + confirmed email) warms the dictionaries for the player's enabled variants while online — on lobby entry and on a variant-preference change — using the per-variant version the profile now advertises, so a later switch to offline mode already has the data. - dict/preload.ts: pure preloadDicts (retry + linear backoff, honours the session dictionary miss-breaker); node-tested. - dict/preloadrun.ts: lazy browser orchestration (real getDawg), imported dynamically so the loader and move generator stay out of the main bundle. - offline.svelte.ts: kickDictPreload, gated by the pure, tested offlinePreloadEligible, plus the reactive first-lobby preload warning. - Header shows a poor-connection notice in the ad-banner slot on a first-lobby preload failure (offline.preloadWarning, en/ru). - App-entry bundle budget 112->113 for the irreducible main-side wiring (documented in bundle-size.mjs); the heavy parts remain lazy chunks.

Ilia Denisov	a9c8f1ecfe	test(offline): real-dictionary move-generator conformance in CI ... Phase A (A4): prove the ported move generator (#188) against the FULL shipped dictionaries, not just the tiny samples — the deep graphs and complete 26/33-letter alphabets the samples cannot reach. - backend/cmd/movegen: add a -dawg-dir mode that emits per-variant golden move-gen vectors from the real dawgs (a bounded first-move + a blank case + a deep 7-tile mid-game position). Regenerated in CI to /tmp, never committed (like the dictgen/validategen vectors), so no dictionary version is pinned into the repo. - ui/src/lib/dict/generate.realparity.test.ts: env-gated (DICT_DAWG_DIR + DICT_MOVEGEN_DIR) parity against that golden — 9 positions across scrabble_en / scrabble_ru / erudit_ru match the Go solver exactly. Skips cleanly when unset. - .gitea/workflows/ci.yaml: the conformance job now generates the movegen golden and points the gated vitest at it (DICT_MOVEGEN_DIR).	2026-07-06 02:16:50 +02:00
Ilia Denisov	c334a9d7b7	feat(offline): port DAWG cursor + move generator to TS (parity-pinned) ... First engine-first step of PWA offline mode (Phase A): the client-side move generator — the "robot brain" a local vs_ai game will run on-device — with no runtime wiring yet (Phase B). - dawg.ts: add the step-by-step cursor (root/final/next/arcs), a faithful port of dafsa traverse.go over the reader's existing bitstream. - generate.ts: the Appel-Jacobson generator (leftPart/extendRight + cross-sets + counts-rack + board transpose + moveKey ranking), reusing the cursor and validate.ts evaluate/connected. A cross-set LetterSet is a Uint8Array, so the 33-letter Russian alphabet (index 32) is exact under JS bit ops. - validate.ts: export connected for the generator's connectivity filter. - backend/cmd/movegen: dev tool building small sample dictionaries and emitting golden move-generation fixtures from the real Go solver (EN + RU). - tests: dawg.cursor.test.ts (enumeration bijection vs indexOf) and generate.parity.test.ts (7/7 vs the Go solver: empty board, mid-game, blank, single-word rule, Russian index-32 cross-set). The committed EN sample also unblocks the existing skipped dawg.parity.test.ts once wired with DICT_* in CI. Pure additive library code; no runtime behavior change.	2026-07-06 01:35:11 +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
