+# Stage 3 accessibility QA
+
+Дата: 18 августа 2026 года. Slice: масштаб текста, high contrast, non-audio state
+и семантика Canvas-экранов.
+
+## Реализованный контракт
+
+- Settings содержит сохраняемые пресеты `Text size: Standard/Large`
+  (`1.0×/1.25×`) и `High contrast: Off/On`;
+- настройки хранятся отдельно от control settings и progress, поэтому миграция не
+  меняет существующие сохранения;
+- оба общих Canvas text helper применяют выбранный масштаб ко всему тексту;
+  viewport и hit mapping остаются неизменными, а фиксированные HUD/card/button
+  области обрезают переполнение внутри своих границ;
+- high contrast использует чёрный фон, непрозрачные кнопки, белые контуры и
+  бело-жёлтый текст; активные механизмы не различаются только цветом;
+- `ON/OFF`, `UP/DOWN`, `OPEN/LOCKED` и постоянная строка
+  `Signals · Doors · Volunteer` дают видимое представление критического состояния
+  при выключенной вибрации;
+- content description меняется для level select, settings, playing, pause и
+  complete; системный Back сохраняет прежний детерминированный контракт;
+- read-only automation surface: `textScaleForAutomation()`,
+  `highContrastForAutomation()`, `screenDescriptionForAutomation()`,
+  `criticalVisibleStatusForAutomation()` и `safeViewportForAutomation()`.
+
+## TDD evidence
+
+- RED: `AccessibilitySettings` отсутствовал, focused JVM-test завершался шестью
+  `cannot find symbol`;
+- GREEN: `Standard/Large`, `Off/On` и безопасное восстановление persisted index;
+- RED → GREEN отдельными циклами: `highContrastEnabled`, `restore`,
+  `canvasTextSize`, `AccessibilityStatus.describe` и
+  `AccessibilityScreenDescription`;
+- RED device compile: отсутствовали persisted/public Settings surface,
+  screen transition и safe-viewport hooks;
+- GREEN device compile: пять focused Android acceptance методов компилируются и
+  проверяют recreation, реальные Settings taps, screen/Back semantics,
+  неизменный safe viewport и textual state при `Vibration: Off`.
+
+## Проверки этого isolated slice
+
+- focused accessibility JVM tests — GREEN;
+- все JVM tests — обязательный gate перед коммитом;
+- `lintDebug`, `assembleDebug`, `compileDebugAndroidTestJavaWithJavac` — обязательный
+  gate перед коммитом;
+- device execution намеренно оставлен финальной интеграционной ветке: этот stream
+  не запускает и не меняет общий emulator.
+
+## Интеграционные замечания
+
+- `GameView` одновременно изменяется onboarding/result и localization slices;
+  при merge нужно сохранить единые text helpers и вызывать refresh semantics после
+  всех новых screen transitions;
+- localized строки должны заменить английский текст и в Canvas, и в content
+  descriptions одним источником, не удаляя read-only acceptance hooks;
+- minSdk 23, control settings, progress format и Stage 2 physics/levels не менялись.
+
+## Финальная интеграция
+
+Все пять device-методов выполнены в составе unfiltered Android 16 gate:
+`OK (30 tests)`, `1,409.366 s`. Итоговая сборка и form-factor evidence описаны в

+# Stage 3 RU/EN localization QA
+
+Date: 2026-08-18
+Scope: persistent, explicit English/Russian language selection for the Canvas UI.
+
+## Delivered contract
+
+- English is the default for missing, null, or unknown stored language codes.
+- The Settings screen exposes a dedicated English/Russian switch without moving the
+  existing control-size, opacity, vibration, or Back touch targets.
+- The selected language is stored separately from progress and control preferences
+  and is restored when `MainActivity` is recreated.
+- `GameStrings` owns all player-facing copy: level select, settings, HUD, respawn,
+  pause, completion, buttons, statistics, ten level titles and hints.
+- Result-flow and onboarding copy has typed RU/EN hooks ready for the other Stage 3
+  slices; new Canvas code does not need language conditionals.
+- Long localized hints, card titles, and best-result summaries are fitted to their
+  existing Canvas bounds. Gameplay geometry and Android `minSdk 23` are unchanged.
+- Automation exposes current/set/toggle language and a read-only snapshot of the
+  localized copy rendered by the current screen.
+
+## TDD evidence
+
+1. RED: the fallback test failed compilation with seven missing `GameLanguage` /
+   `GameStrings` symbols. GREEN: English default and safe unknown/null fallback.
+2. RED: the complete Russian-pack test failed compilation with ten missing copy
+   methods. GREEN: complete RU pack, ten titles/hints, statistics, plural forms,
+   result hooks, and onboarding hooks.
+3. RED: the persistence device test failed compilation with four missing GameView
+   language hooks. GREEN: Settings toggle plus a dedicated preference store.
+4. RED: the integrated acceptance extension failed compilation with three missing
+   setter/snapshot hooks. GREEN: explicit language setter and current-screen copy
+   snapshot.

+| Gate | Result |
+| --- | --- |
+| `testDebugUnitTest` | GREEN, 22/22 JVM tests |
+| `lintDebug` | GREEN |
+| `assembleDebug` | GREEN |
+| `compileDebugAndroidTestJavaWithJavac` | GREEN, including `GameLanguagePersistenceTest` |
+| Canvas raw-copy audit | GREEN; only language-neutral `II` and numeric formats remain in draw calls |
+
+`GameLanguagePersistenceTest` is compiled here but intentionally not executed in
+this isolated stream because emulator ownership belongs to final Stage 3 integration.
+It performs real Settings taps and verifies Russian visible-copy snapshot, Activity
+recreation, progress, control size, opacity, and vibration preservation.
+
+## Integration notes
+
+- `GameView.java` will conflict with accessibility/onboarding/result branches. Keep
+  their UI behavior and route every new visible string through the existing
+  `GameStrings` result/onboarding hooks.
+- `ControlSettings.java` is not modified; localized preset labels are derived from
+  its stable package-visible preset indexes.
+- `LevelCatalog.java` and level geometry are not modified. Canvas rendering now uses
+  `GameStrings.levelTitle/levelHint`; the existing English fields remain compatible
+  with gameplay tests and older callers.
+
+## Final integration
+
+`GameLanguagePersistenceTest` and the combined Stage 3 RU/EN acceptance tests passed
+inside the unfiltered Android 16 gate: `OK (30 tests)`, `1,409.366 s`. See
+[`STAGE3_QA_REPORT.md`](STAGE3_QA_REPORT.md) for the release evidence.

+# Stage 3 onboarding and result QA
+
+Дата: 18 августа 2026 года. Базовая сборка: `0.5.0-stage3-controls-debug`
+(`minSdk=23`). Этот документ описывает независимый slice обучения и результата;
+версия финального Stage 3 APK будет назначена после интеграции всех веток.
+
+## Реализовано
+
+- при первом входе в уровень показывается компактная карточка из трёх подсказок:
+  движение, одновременные движение и прыжок двумя пальцами, использование тел;
+- карточка не останавливает физику и не отключает экранное управление;
+- доступны `Skip`, пошаговый `Next` и финальный `Done`;
+- закрытие сохраняется в отдельном versioned storage
+  `project_sacrifice_onboarding_v1` и не изменяет progress/control settings;
+- результат разделяет показатели текущего прохождения и сохранённые лучшие время
+  и число добровольцев;
+- результат показывает оба target и выбирает понятную следующую цель: улучшить
+  число добровольцев, время, перейти на следующий уровень либо улучшить personal best;
+- `Level select`, `Replay` и `Next level` используют общий navigation contract и
+  не очищают прогресс или настройки управления.
+
+## TDD evidence
+
+- `OnboardingFlowTest`: RED — `cannot find symbol: class OnboardingFlow`; GREEN — 2/2;
+- `CompletionResultTest`: RED — `cannot find symbol: class CompletionResult`; GREEN — 2/2;
+- `OnboardingStoreTest`: RED — `cannot find symbol: class OnboardingStore`; после
+  реализации AndroidTest compile GREEN;
+- `OnboardingAndResultFlowTest`: RED — отсутствовали публичные GameView contracts
+  обучения/result navigation; после интеграции AndroidTest compile GREEN.
+
+## Выполненные проверки
+
+```text
+./gradlew testDebugUnitTest lintDebug assembleDebug compileDebugAndroidTestJavaWithJavac
+BUILD SUCCESSFUL
+```
+
+- JVM: 24/24, failures=0, errors=0;
+- `lintDebug`: GREEN;
+- `assembleDebug`: GREEN;
+- все Android instrumentation sources: compile GREEN;
+- `git diff --check`: GREEN.
+
+По ограничению stream-задачи emulator/connected tests в этой ветке не запускались.
+После интеграции необходимо выполнить `OnboardingStoreTest` и
+`OnboardingAndResultFlowTest` на Android 16 вместе с полным Stage 2 regression gate.
+
+## Приёмка на устройстве после интеграции
+
+1. Очистить данные приложения, открыть уровень 1 и убедиться, что карточка не
+   мешает одновременно удерживать направление и нажимать Jump.
+2. Проверить отдельно `Skip` и полный путь `Next` → `Next` → `Done`, затем cold
+   launch: обучение не должно появиться повторно.
+3. Завершить уровень хуже сохранённого результата: `This run` не должен подменять
+   `Saved best`.
+4. По очереди проверить `Level select`, `Replay`, `Next level`; завершённость
+   уровня, unlocked level и control preset должны сохраниться.
+
+## Финальная интеграция
+
+`OnboardingStoreTest`, оба `OnboardingAndResultFlowTest` и объединённый RU/EN
+acceptance прошли в составе unfiltered Android 16 gate: `OK (30 tests)`,
+`1,409.366 s`. Релизная версия назначена `0.6.0-stage3-complete`; общий отчёт:
+[`STAGE3_QA_REPORT.md`](STAGE3_QA_REPORT.md).

+# Stage 3 QA report
+
+Дата: 18 августа 2026 года.
+
+Версия: `0.6.0-stage3-complete` (`versionCode=7`).
+
+## Результат
+
+Инженерный scope этапа 3 завершён. В общую сборку интегрированы:
+
+- сохраняемые размер и прозрачность touch-controls и режим вибрации;
+- Standard/Large text, high contrast, видимые состояния сигналов, дверей и respawn;
+- локализованные accessibility descriptions;
+- полная RU/EN локализация Canvas UI, десяти названий и подсказок уровней;
+- неблокирующее трёхшаговое обучение с постоянным Skip/Done;
+- result screen с текущим и лучшим результатом, targets, следующей целью и
+  рабочими переходами Levels/Replay/Next;
+- совместная сохранность языка, accessibility, controls и прогресса после recreate;
+- state-driven боты уровней 1–10, restart-free recovery уровня 8 и проверка
+  неподвижного тела на lift-плите уровня 10.
+
+## Автоматические проверки
+
+Финальный clean gate:
+
+```text
+./gradlew clean testDebugUnitTest lintDebug assembleDebug assembleDebugAndroidTest
+BUILD SUCCESSFUL
+66 actionable tasks
+42/42 JVM tests
+```
+
+Финальный unfiltered device gate выполнен на холодно запущенном Android 16 AVD,
+физический размер `1080x2400` (20:9), после установки точных APK clean-сборки и
+`pm clear com.projectsacrifice.game.debug`:
+
+```text
+AndroidJUnitRunner
+Tests run: 30
+Time: 1,409.366 s
+OK (30 tests)
+```
+
+Runner запускался без `-e class`, retries и повторного запуска отдельных методов.
+Матрица включает все intended routes уровней 1–10 по три раза, дополнительные
+stressed/recovery маршруты уровня 8, throttled mastery и sliding-body regression
+уровня 10, lifecycle, restart и все Stage 3 persistence/UI contracts.
+
+До финального объединения UI contracts также прошли на логических viewport:
+
+- 16:9 safe viewport — GREEN, `66.208 s`;
+- 16:10 tablet-sized `2560x1600` landscape — GREEN, `167.823 s`;
+- focused Stage 3 matrix — 14/14 GREEN, `576.355 s`.
+
+Последующие изменения касались automation/read-only snapshot и не меняли UI
+геометрию; финальный 20:9 gate повторно проверил весь интегрированный интерфейс.
+
+## RED → GREEN evidence
+
+Первый полный 30-тестовый прогон был завершён полностью и дал 27/30 GREEN. Три
+нагрузочные границы были исправлены без изменения физики уровней или retry:
+
+1. Level 3: takeoff начинался на несколько пикселей поздно (`x=505.67633`,
+   `y=664.41797`, лишняя смерть). State-driven точка старта получила запас и
+   повторно прошла 3/3 внутри полного load-order.
+2. Level 6: координатный checkpoint не доказывал опору на frozen block; добавлен
+   обязательный `playerOnGround`, после чего landing route прошёл 3/3.
+3. Level 10: бот мог прыгнуть на лифт во время его восходящей фазы и упасть в PIT
+   (`x=1942.7063`, deaths=4). Snapshot расширен read-only направлением движения;
+   посадка разрешается на нисходящей фазе, normal 3/3 и throttled route GREEN.
+
+Level 8 отдельно получил исходящую фазу горизонтальной платформы, безопасное
+позиционирование под recovery relay и перед финальным прыжком. Финальный suite
+подтвердил stressed 1/1, intended 3/3 и recovery 3/3 без смерти/restart.
+
+## Проверка APK
+
+Финальный `app-debug.apk` проверен как самостоятельный устанавливаемый артефакт:
+
+- ZIP/APK-структура: `unzip -t` без ошибок;
+- package: `com.projectsacrifice.game.debug`;
+- версия: `versionCode=7`, `versionName=0.6.0-stage3-complete-debug`;
+- `minSdkVersion=23`, `targetSdkVersion=34`;
+- подпись: `apksigner verify` GREEN, схемы v1 и v2;
+- SHA-256: `7be25ea96cf0de7ea1930335b3570bd9def93cdb48029e24e4c9c14078e4195d`;
+- clean install и cold launch на Android 16: `Status: ok`, `LaunchState: COLD`,
+  `TotalTime: 1401 ms`; crash-буфер пуст.
+
+## Границы приёмки
+
+Инженерный Stage 3 gate закрыт. Отдельная задача ручного внешнего playtest остаётся
+открытой: реальные тестировщики должны пройти каждый уровень без подсказок
+разработчика. Этот внешний протокол не подменяется автоматическими ботами.
