+# Agent field notes — scrabble-game
+
+Non-obvious, hard-won project knowledge that is **not** in the main docs (`CLAUDE.md`, `docs/*`,
+`deploy/README.md`). Kept in the repo so it travels with a clone to any host. These are working
+memory, not a spec — **verify any named file / flag / function against the current code before acting
+on it**, and prefer the authoritative docs where they overlap. Add to this file as new gotchas turn up.
+
+## Codegen & build
+
+- **jetgen churns everything.** `backend/cmd/jetgen` regenerates go-jet code for *all* tables and may
+  reorder output. After running it, revert the churn on tables you did not touch and commit only your
+  table's change.
+- **flatc is version-pinned** (`pkg/Makefile`, `REQUIRED_FLATC = 23.5.26`, hard-checked). A different
+  flatc silently churns the generated wire code and can flip wire defaults. Never regenerate FBS with
+  another flatc version.
+- **gopls lags codegen.** Right after an FBS/jet regen, gopls shows phantom "undefined" errors. Trust
+  `go build` / `go test`, not the editor squiggles.
+- **go-jet type mapping:** SQL `numeric` → `float64`, `interval` → `string`. Never store money as
+  `numeric` (float precision loss) — use **bigint minor units + a `Money` type**; store durations as
+  **int seconds**, not `interval`.
+- **`go mod tidy` chokes on dot-free local module paths** (`scrabble/...`). Hand-edit `go.mod` when a
+  bump is needed. The solver (`../scrabble-solver`) is consumed via `go.work` replace locally, but a
+  prod bump goes through a solver **PR → master + a published tag**, not a local replace.
+- **Run the whole CI suite locally before pushing** — unit + integration (`//go:build integration`,
+  Postgres) + the UI job + codegen check. Do not lean on CI to catch what a local run would.
+- **CI runner shares this host's `/tmp` as a different user.** In workflow steps, write artifacts to
+  `${GITHUB_WORKSPACE}`, never a fixed `/tmp/...` path (cross-user permission failures otherwise).
+- **pnpm corepack pre-flight flakes.** `pnpm exec` / `pnpm check` occasionally abort on a corepack
+  pre-flight. Dodge it by invoking the tool directly: `node_modules/.bin/<tool>`.
+
+## Native Android build (Capacitor)
+
+The native Android app (`ANDROID_PLAN.md`) is a Capacitor 8 wrapper of the `ui` SPA, scaffolded under
+`ui/` (a Node project outside `go.work`). Hard-won bring-up facts — verify against current code:
+
+- **Capacitor 8 needs JDK 21, not 17.** `@capacitor/android` compiles at `VERSION_21`; a JDK 17 Gradle
+  run dies with `error: invalid source release: 21`. Install sudo-free via the Homebrew **formula**
+  `brew install openjdk@21` (the `temurin@21` **cask** wants sudo for a system `.pkg`, unusable
+  non-interactively) + a user symlink into `~/Library/Java/JavaVirtualMachines/` so
+  `/usr/libexec/java_home -v 21` finds it. JDK 17 stays fine for `sdkmanager`/`avdmanager`.
+- **Cap 8 SDK pins:** compileSdk/targetSdk **36**, minSdk **24**, Gradle **8.14.3**, AGP **8.13.0**
+  (`ui/android/variables.gradle`). Install `platforms;android-36` — Android Studio's newer
+  `android-36.1` does NOT satisfy compileSdk 36.
+- **SDK is Android Studio's** at `~/Library/Android/sdk` (no `cmdline-tools` by default → `brew install
+  --cask android-commandlinetools`, then `sdkmanager`/`avdmanager --sdk_root=$HOME/Library/Android/sdk`).
+  Gradle finds it via **`ANDROID_HOME`** (`local.properties` is gitignored, machine-specific).
+- **Build recipe:** `cd ui && pnpm build && node_modules/.bin/cap sync android`; then `cd ui/android &&
+  ANDROID_HOME=~/Library/Android/sdk JAVA_HOME=$(/usr/libexec/java_home -v 21) ./gradlew assembleDebug`
+  → `ui/android/app/build/outputs/apk/debug/app-debug.apk`. Prefer the local `ui/node_modules/.bin/cap`
+  (dodges the corepack flake).
+- **Emulator smoke:** existing AVDs `Pixel_10` / `Pixel_4_Android_10_API_29` / `Pixel_Android_9`;
+  `emulator -avd <name>`, `adb install -r <apk>`, `adb shell monkey -p ru.eruditgame.app -c
+  android.intent.category.LAUNCHER 1`, `adb exec-out screencap -p > x.png`. The boot wait needs `sleep`
+  → run it as a **background** Bash task (foreground `sleep` is blocked). Browsers/WebView are cached, so a
+  full offline vs_ai turn is drivable via `adb shell input tap` (tap through the first-run coachmark tour —
+  each tap advances one step — then Hint places a suggested word; commit → the robot replies).
+- **Android 15+ edge-to-edge safe-area (WebView-version-dependent, bit me on API 37).** targetSdk 36 forces
+  edge-to-edge — the WebView draws behind the status bar (top) and the gesture-nav home indicator (bottom).
+  On Android **WebView < 140**, `env(safe-area-inset-*)` wrongly reports **0**, so chrome relying on it draws
+  under the bars and is untappable: the top nav under the clock, and the game's bottom action bar's **centre**
+  button (Hint) under the home-indicator pill (side buttons still work; `navigation_mode`=2 is gesture nav).
+  Fix is CSS-only, in TWO parts: (1) Capacitor 8's **SystemBars** plugin (built into `@capacitor/core`,
+  `insetsHandling:'css'` default — no dep, no config) injects correct `--safe-area-inset-*`; consume them as
+  `--tg-safe-*: var(--safe-area-inset-*, env(safe-area-inset-*, 0px))` (`ui/src/app.css`) — fixes any consumer
+  that ALREADY applies the token (the bottom bars: `Game.svelte`/`Screen.svelte` `--tg-safe-bottom`).
+  (2) But a consumer that never applied the top inset on the native path is NOT fixed by the token alone — the
+  **header's** top inset was Telegram-fullscreen-scoped only, so the native header sat under the status bar on
+  EVERY WebView; it needed its own `.bar { padding-top: calc(var(--safe-area-inset-top, 0px) + 5px) }`
+  (`Header.svelte`, native-only via the plugin var; tg-fullscreen still overrides via specificity). **Measure
+  per element, don't eyeball** — a centred title at y=11 under a 54px bar reads as "fine" in a screenshot but
+  is overlapping; an emulator WebView auto-updated to ≥140 (Chrome 149) also hides the `env()`=0 half (so the
+  BOTTOM looks fine there while the user's < 140 device overlaps). **Inspect a live debug WebView** over CDP:
+  `adb forward tcp:9222 localabstract:$(adb shell cat /proc/net/unix | grep -o 'webview_devtools_remote_[0-9]*'
+  | head -1)`, then Playwright `chromium.connectOverCDP('http://localhost:9222')` → `page.evaluate` (read each
+  element's `getBoundingClientRect().top`, and `--safe-area-inset-*` vs `env(...)`).
+- **`sharp` is whitelisted** in `ui/pnpm-workspace.yaml` (`allowBuilds: sharp: true`) — `@capacitor/assets`
+  uses it for `pnpm android:assets` (launcher icon/splash); else pnpm 11 raises `ERR_PNPM_IGNORED_BUILDS`.
+- **Bundled offline dicts come from the `scrabble-dictionary` release** (`scrabble-dawg-<DICT_VERSION>.tar.gz`,
+  keyed on the `DICT_VERSION` Gitea var — the same source the backend image + CI `curl`), NOT
+  `scrabble-solver/dawg` (those are the solver's pinned test fixtures).
+
+## Wire / schema evolution (client ↔ gateway ↔ backend)
+
+- **FBS is additive-only.** Add **trailing** fields ("added trailing — backward-compatible"). Never
+  delete or reorder a mid-table field — **deprecate** it (`(deprecated)`); deleting shifts field IDs
+  and breaks older readers.
+- **Retiring a domain field must also retire the WIRE field it fed** — by deprecation, not deletion,
+  and do not just zero it: a dead `0` the client dutifully syncs will clobber the real value.
+- **The gateway transcodes FBS ↔ backend JSON DTOs in lockstep.** A wire change usually means editing
+  both the FBS schema and the backend DTO.
+- **Seat display name is built in two places** — `game.Service` live events **and** the server REST
+  DTOs. Change both or they drift.
+- **A per-viewer flag is computed only in the per-viewer REST DTO**; the client seeds it from REST,
+  then bumps it from the live event. Don't expect it on the shared broadcast.
+
+## UI / Svelte 5
+
+- **Never name a `$state` variable `state`.** `svelte-check` then misreads `$state` as a store
+  subscription. Rename (e.g. `view`).
+- **Svelte trims literal edge whitespace** in markup. To keep a separator space, emit an expression:
+  `{' : '}`.
+- **No global `.btn` / `.ghost` button classes.** Style buttons per-component with scoped CSS + design
+  tokens (mirror `NewGame`'s `.invite`).
+- **A `$state` proxy fails structured-clone** when persisted to IndexedDB. Snapshot at the call site
+  with `$state.snapshot(...)` before storing.
+
+## Platform / WebView quirks (Telegram, VK, iOS, native, old Android)
+
+- **Telegram `showPopup` eats the user-activation.** Share / clipboard called from inside a
+  `showPopup` callback fail (no gesture). Use your own `Modal` for gesture-gated Web APIs.
+- **iOS Telegram `<a download blob:>` navigates away** and strands the SPA. Deliver files by **Web
+  Share on mobile**, and only use a `<a download>` Blob path on **desktop**.
+- **Android TG/VK WebViews** lack `navigator.share` and ignore `<a download>`. Deliver a
+  client-generated file by **copying it to the clipboard**.
+- **VK Android WebView ignores `target=_blank`.** Open external links through `lib/links.ts`
+  (routes to `vk.com/away.php`). Verify on-device.
+- **Per-platform file-delivery last hop differs** (TG / VK / plain browser) — there is a delivery
+  matrix; do not re-litigate it without new on-device facts.
+- **Old Android System WebView floor ≈ Chrome 67.** The bundle targets **es2019** (esbuild lowers
+  syntax), a conditional `core-js` polyfill loads only on old engines, and `index.html` has a boot
+  gate (BigInt / Proxy are the hard block → the unsupported-engine screen). There's also a `vmin`
+  glyph fallback for old rendering.
+- **iOS WKWebView overscroll and Telegram swipe-to-close are not reproducible in Playwright.** Verify
+  those live on the deployed contour, not in the e2e.
+- **Telegram Desktop Mini App shows a persistent bottom-right loader** — that's the long-lived
+  Subscribe stream, cosmetic, deliberately left as-is.
+
+## Testing
+
+- **UI test layers:** vitest (node env, pure logic, **no jsdom**) + Playwright **mock** e2e. The mock
+  e2e **bypasses the codec**, so wire/codec bugs need **codec unit tests**, not e2e coverage.
+- **Mock overlay blocks e2e.** The cold-load overlay must be instant under the mock build or it
+  intercepts Playwright taps.
+- **Mock tile pools lack a blank `'?'`.** The seeded game `G1` hard-codes one; flip `G1`'s variant to
+  eyeball per-variant tiles.
+- **Durable Playwright MCP servers** (chromium + webkit) exist for UI inspection (there's a
+  plugin-config gotcha in wiring them).
+- **The `playwright test` runner can't *fetch* browsers in this sandbox** — `playwright install` dies
+  with `EBADF` against the Playwright CDN (blocked network), even with the sandbox off. Run the e2e in
+  **CI** (the `ui` job installs chromium+webkit), or drive a state live through the **Playwright MCP**
+  browser against a local `vite --mode mock` server for visual verification. **But if chromium/webkit are
+  already cached** in `~/Library/Caches/ms-playwright/`, `playwright test` runs locally fine (only the CDN
+  fetch is blocked) — the native offline-first e2e was run green locally this way (chromium + webkit),
+  its dawgs from the sibling `../../scrabble-solver/dawg` via the webServer's `bundle-dicts.mjs` fallback.
+- **A native (Capacitor) e2e must inject `window.androidBridge`, NOT `window.Capacitor.getPlatform`.**
+  `@capacitor/core` (pulled in during boot by `initNativeShell`'s dynamic `@capacitor/app` import)
+  **replaces** any pre-set `window.Capacitor` with its own shim and derives the platform from
+  `window.androidBridge` (android) / `window.webkit.messageHandlers` (ios) — so a bare injected
+  `Capacitor.getPlatform: () => 'android'` is clobbered to `web` and the boot falls to `/login`. Inject
+  `window.androidBridge = { postMessage(){} }` in an `addInitScript` (see `e2e/native.spec.ts` `simulateNative`);
+  `initNativeShell` is written to tolerate the stub bridge (`try/catch` round the `@capacitor/app` addListener).
+- **`docker run -p ...` boot tests fail from the shell** (published ports unreachable in this env).
+  Use **testcontainers** for container-backed tests.
+- **Distroless images run as UID 65532 (nonroot).** Bind-mounted TLS keys must be **0644** (not 0600)
+  or the service crash-loops on start.
+
+## Deploy / test contour (operational)
+
+- **The TEST contour runs on THIS dev host.** Inspect it via `docker` / Prometheus. A host-side
+  `curl` to caddy **hangs** (NAT hairpin) — don't debug the edge that way.
+- **The contour's client IP is the home-router SNAT address**, not the real external IP. Correct in
+  prod, not a bug — which is why the IP ban / blocklist are **prod-only**.
+- **The contour is one shared env, last-deploy-wins.** Keep a multi-PR batch a **linear stack** (one
+  PR, one deploy) so deploys don't clobber each other.
+- **A schema/wire PR breaks the contour** until a `DROP SCHEMA` + backend restart. Note such a
+  prerelease step in `PRERELEASE.md`.
+- **A contour DB wipe resets the account but not the client's stored locale**; the reconciler then
+  syncs the stale locale, masking a fresh TG `language_code` seed. Clear client prefs too when testing
+  locale.
+- **`DNS=` in `TEST_AWG_CONF` pins the VPN netns to 1.1.1.1** → internal names go NXDOMAIN → the
+  bot-link silently dies. Diagnose from inside the netns.
+- **Swap one contour service to a local image** without deploy secrets via a busybox-in-the-netns
+  socket-inspect trick (single-service recreate).
+- **A rolling deploy did NOT recreate caddy on a config-only change.** Force `--force-recreate` for
+  caddy; don't trust "deploy green" for an edge-config change.
+- **A new gateway edge route MUST be added to the Caddyfile `@gateway` matcher** or it falls through
+  to the landing catch-all. Add a CI probe for the route.
+- **Prod caddy logs warnings only, no access log.** Trace a request via the backend "http request"
+  telemetry log or Tempo, not caddy.
+- **Confirm a release is live without SSH** by grepping the served SPA: `__APP_VERSION__` inside
+  `/assets/main-*.js`.
+- **"App hangs on load" was a dead HTTP/3 advert:** caddy sent `Alt-Svc: h3` with no UDP/443 open;
+  clients cache it ~30 days. Fix with `Alt-Svc: clear`.
+- **Config-poison deploy loop:** a crash-looping config-mounted service + a missing bind source
+  produces a root-owned directory that then fails deploys. Break it by removing the root-owned dir.
+- **Maintenance-window contract** (planned-deploy 503): a marker header, `/_gm` exempt, the flag spans
+  the whole roll, the SPA overlay reloads on recovery. Don't break these invariants.
+- **A new dictionary goes live via a `/_gm/dictionary` upload, NOT a redeploy.** In-flight games keep
+  their pinned version. The **owner** does the upload.
+- **Renderer deploy job flakes** on the skia-canvas GitHub binary download when its lockfile changes —
+  re-run, it's not your code.
+
+## Repo workflow
+
+- **PR-based, zero issues.** Work is tracked via PRs + `PRERELEASE.md`. "заведи задачу" means *do it*
+  / add a plan line — not file a tracker issue.
+- **`tea` CLI for all Gitea ops** (PRs, secrets, variables, dispatch). `gh` does **not** work here. The
+  agent **cannot self-approve** a PR but **can merge** it after the owner approves. Watch the
+  stale-mergeable trap (re-check mergeability right before merging).
+- **Watch every push/merge/deploy to green** with `python3 ~/.claude/bin/gitea-ci-watch.py`, launched
+  **bare** under a background task. It polls run-level conclusions; its `ALL GREEN` already covers the
+  gated deploy job. Pass `--no-runs 600` when the runner is busy. A **merge** is the most-forgotten
+  case — watch the post-merge runs too.
+- **After a merge, switch to the merged-into branch** (`development`/`master`), pull, and prune the
+  local feature branch.
+- **The contour deploy probe checks the backend `/readyz`**; a PR deploy builds the PR's own code; a
+  wedged contour can be recovered by recreating the host container set.
+
+## Domain semantics (not obvious from the code)
+
+- **Account deletion must NOT delete any user messages** — including feedback / support. Interview the
+  owner on every deletion point before wiring it.
+- **`account.time_zone` is `NOT NULL DEFAULT 'UTC'`, seeded from a detected ±HH:MM offset.** An email
+  account row is created at the **code-request** step, not at confirmation.
+- **The robot has two distinct time windows:** a **sleep window** (~00:00–07:00, gates its moves and
+  nudges) vs the **player away window** (turn-timeout only). "окно отсутствия" in dialogue = the
+  **sleep** window.
+
+## Production topology
+
+- **Two prod hosts.** `main` — full stack + ACME/edge (Selectel); `tg` — Telegram bot only (vdsina).
+  SSH aliases `scrabble-main-ops` / `scrabble-tg-ops`. Deploy is **manual dispatch only**, rolling +
+  health-gated + auto-rollback. Hosts are provisioned by `deploy/ansible/` (inventory + vars there —
+  the source of truth for IPs/roles).
+- **The agent has targeted root SSH** to the hosts (and may run the prod Ansible). Surface every
+  owner-side step **before** a deploy, not after.
+
+## Feature-area pointers (state lives in the linked docs/plans, not here)
+
+- **Monetization** — «Фишка» currency, per-platform wallets, ads. Agreements in
+  `docs/PAYMENTS_DECISIONS_ru.md`; a phased plan (E0–E9). go-jet money rule above applies.
+- **PITR** — pgBackRest → Selectel S3 (encrypted, 30-day), currently **gated off**; runbook in
+  `deploy/README.md`. Gotcha: run pgBackRest via docker-exec **as the `postgres` user** with
+  `--pg1-user=scrabble`.
+- **Offline mode** — the robot brain, move generator/validator/scorer and DAWG reader are **JS ports**
+  of the Go engine, bundled client-side and **parity-pinned** by golden tests. Multi-phase; native
+  offline-first bundles the dictionaries (see `ANDROID_PLAN.md`).
+- **VK ID web login** — raw OAuth 2.1 against `id.vk.com`, a **separate VK "Web" app** from the Mini
+  App, server-side confidential code exchange.
+- **Email relay** — Selectel SMTP + confirm / link / unlink / deletion codes + alerts.
+- **Native Android** — see `ANDROID_PLAN.md` (Capacitor bundle model, client-version gate,
+  offline-first, RuStore).

+## Android app build & release (RuStore)
+
+The standalone Android app is built by a **manual** workflow, never automatically, and is separate from the
+web/prod rollout — a signed APK uploaded to RuStore by hand. Full plan: [`../ANDROID_PLAN.md`](../ANDROID_PLAN.md).
+
+- **Trigger:** `Actions → android-build → Run workflow` from **`master`**, input `confirm=build` (mirrors
+  `prod-deploy`). **Tag the release first** (`git tag vX.Y.Z` on `master`) — the workflow refuses anything
+  but a clean `vMAJOR.MINOR.PATCH` and derives `versionCode = MA*1_000_000 + MI*1_000 + PA`,
+  `versionName = MA.MI.PA`. Watch it green with `python3 ~/.claude/bin/gitea-ci-watch.py`.
+- **Output:** a `release APK` run artifact — **signed** when the signing secrets are present, an
+  **unsigned** release APK otherwise (a dry run still proves the pipeline).
+- **Runner (host-executor):** JDK 21 comes from `setup-java`; the **Android SDK is host-provisioned** —
+  install it once (`sdkmanager 'platform-tools' 'platforms;android-36' 'build-tools;36.0.0'`) and grant the
+  `runner` user read+exec (`sudo chmod -R a+rX /opt/android-sdk`). Override the path with the
+  `ANDROID_SDK_DIR` variable. The workflow's `Verify the host Android SDK` step fails fast with the fix if
+  the SDK is missing or unreadable.
+- **Release keystore** (create once, **back up off-host** — losing it means the app can never be updated):
+  `keytool -genkeypair -v -keystore erudit-release.jks -alias erudit -keyalg RSA -keysize 4096 -validity 10000`,
+  then set the Gitea **secrets** `ANDROID_KEYSTORE_BASE64` (`base64 -w0 erudit-release.jks`),
+  `ANDROID_KEYSTORE_PASSWORD`, `ANDROID_KEY_ALIAS`, `ANDROID_KEY_PASSWORD`. Set the `ANDROID_RUSTORE_URL`
+  variable to the store listing once published (empty until then — the in-app update button no-ops).
+- **Wire-break discipline:** the prod deploy that ships an incompatible wire change **also** bumps
+  `GATEWAY_MIN_CLIENT_VERSION` to that release (see Optional variables), so an old installed APK is turned
+  away cleanly instead of failing blind.
+- **Upload:** download the artifact and upload it to RuStore by hand (no automated RuStore-API upload in the MVP).

+- **Client-version gate — two tiers** (native long-tail protection): a bundled native install (§13) can be
+  arbitrarily old, so the client stamps its build into an **`X-Client-Version`** request header (the app
+  version from `pkg/version` / `__APP_VERSION__`), read by the gateway **before it decodes the FlatBuffers
+  payload**. The version rides the **outermost stable layer** — an HTTP header, never the FBS payload —
+  because protobuf envelopes and headers are version-tolerant by design while the FBS payload is the layer
+  that breaks. Enforcement is **per-call, not a Hello RPC** (`Execute`/`Subscribe` check it at the top,
+  before registry lookup / auth / decode), so the first online call is already gated. Both tiers **fail
+  open** (an absent or unparseable header passes) and are **dormant** until deliberately configured (both
+  vars empty ⇒ off, web behaviour unchanged).
+  - **Hard (critical) — `GATEWAY_MIN_CLIENT_VERSION`**: `version < min` ⇒ the domain envelope
+    `result_code = "update_required"` (HTTP 200) on `Execute` and `CodeFailedPrecondition` on `Subscribe`;
+    the client makes **zero** successful requests. Its reaction is **graceful, not terminal**: it enters
+    `offlineVersionLocked` (offline mode) and shows a **dismissable notice** — **"Update"** (native → the
+    store listing `VITE_RUSTORE_URL`, web → reload) or **"Play offline"** (dismiss → keep playing local
+    vs_ai / hotseat). The lock is sticky until an actual update on the next launch.
+  - **Soft (recommended) — `GATEWAY_RECOMMENDED_CLIENT_VERSION`**: `min ≤ version < recommended` ⇒ the
+    gateway sets an **additive** `X-Update-Recommended: 1` **response header** on the served `Execute`
+    response (the call still succeeds); a transport interceptor turns it into a **dismissable "update
+    available" nudge** in the lobby — play continues, nothing blocks. `recommended` must be **≥ `min`**
+    (validated at config load); empty ⇒ the soft tier is off.
+- **Frozen wire contract** (so any build, however old, can always recognise "update required"): three
+  things are permanent — (1) the protobuf envelope field numbers in `edge.proto` are never renumbered or
+  reused; (2) the `update_required` sentinel — the `result_code` string **and** the `FailedPrecondition`
+  code — never changes; (3) the FBS schema stays **additive** (append trailing fields; `(deprecated)`, never
+  delete — deleting shifts field IDs and breaks older readers). A breaking wire change happens only *inside*
+  the FBS payload, which is exactly what the gate guards. **Deploy discipline:** the production rollout that
+  ships an incompatible wire change **also** bumps `GATEWAY_MIN_CLIENT_VERSION` to that release, in the same
+  rollout (see [`../deploy/README.md`](../deploy/README.md)).
+- **Gate × offline** (UX rule): offline is the net-state machine's `offlineNoNetwork` / `offlineVersionLocked`
+  (implicit — no toggle) and its kill switch refuses calls, so the hard gate never fires *while already

+When a new client version is required, the app does not lock you out. On the **native** app a

+The game also ships as a standalone **Android app** (first on **RuStore**), a packaged build of the same
+client. Everything it needs is bundled, so it opens with **no network**: a first launch offline drops you
+straight into the lobby as a **guest** (no sign-in wall) and you can play right away — against the robot, or

+opponents, friends, statistics) light up without interrupting play; local games you started offline stay on
+the device. To keep a durable account you sign in with **email** from Profile (the guest becomes your
+account); Telegram and VK sign-in are not offered in the native app. In-app purchases are hidden in this

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
