+# 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.
+

+# 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.
+
+## Automated checks
+
+| 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

+## Реализовано
+
+- при первом входе в уровень показывается компактная карточка из трёх подсказок:
+  движение, одновременные движение и прыжок двумя пальцами, использование тел;

+- 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;

+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.

+
+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`;

+- 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.

+# Stage 4: формат уровней и контентные инструменты
+
+## Назначение
+
+Все десять уровней находятся в Android-independent модуле `level-format` и
+загружаются из `level-format/src/main/resources/levels`. Runtime, unit-тесты и
+desktop-команды используют один и тот же JSON parser, catalog loader и validator.
+Изменение геометрии или текста не требует изменения игрового Java-кода.
+
+Текущие версии контракта:
+
+- `formatVersion: 1` — схема JSON;
+- `physicsVersion: 1` — набор физических допущений, для которого создан уровень;
+- bot `traceVersion: 1` — формат журнала acceptance-команд.
+
+Неизвестная версия отклоняется. Поддержка новой версии должна добавляться явно,
+вместе с migration/tests, без молчаливого fallback.
+
+## Каталог
+
+`levels/index.json` задаёт точный порядок уровней и содержит те же версии:
+
+```json
+{
+  "formatVersion": 1,
+  "physicsVersion": 1,
+  "levels": ["level-01.json", "level-02.json"]
+}
+```
+
+Имена в каталоге должны быть уникальны, ресурсы должны существовать, а поле
+`number` каждого загруженного уровня должно соответствовать позиции в списке.
+
+## Схема уровня
+
+Минимальный характерный пример:
+
+```json
+{
+  "formatVersion": 1,
+  "physicsVersion": 1,
+  "number": 3,
+  "copy": {
+    "en": {"title": "Dead Weight", "hint": "Leave a body on the plate."},
+    "ru": {"title": "Мёртвый груз", "hint": "Оставьте тело на плите."}
+  },
+  "world": {"width": 2050, "height": 1080},
+  "spawn": {"x": 130, "y": 760},
+  "goal": {"x": 1810, "y": 770, "width": 86, "height": 110},
+  "targets": {"deaths": 1, "seconds": 50},
+  "platforms": [
+    {"box": {"x": 0, "y": 880, "width": 2050, "height": 200}}
+  ],
+  "hazards": [
+    {"type": "SAW", "box": {"x": 565, "y": 760, "width": 92, "height": 92},
+     "impulseX": 0, "impulseY": -150}
+  ],
+  "switches": [
+    {"type": "PRESSURE", "box": {"x": 540, "y": 860, "width": 150, "height": 20},

+  ],
+  "doors": [
+    {"box": {"x": 1110, "y": 570, "width": 78, "height": 310},
+     "requiredSignals": ["gate"]}
+  ]
+}
+```
+
+Поддерживаемые значения:
+
+- hazards: `SPIKES`, `SAW`, `FREEZER`, `ELECTRIC`, `PIT`;
+- switches: `PRESSURE`, `TOGGLE`, `TIMED`;
+- static platform: только `box`;
+- moving platform: `box`, ненулевой `travelX` или `travelY`, положительный
+  `periodSeconds`, опциональный `controlId`;
+- electrical hazard может публиковать `relayId`;
+- door перечисляет все `requiredSignals` (AND-семантика).
+
+## Валидация
+
+Валидатор проверяет до упаковки APK:
+
+- известные format/physics versions;
+- конечные положительные размеры мира и объектов;
+- spawn, goal, платформы, hazards, switches, doors и конечную позицию moving
+  platform внутри мира;
+- наличие хотя бы одной платформы;
+- неотрицательный target deaths и положительный target seconds;
+- непустой signal ID, положительный required mass и положительную длительность
+  `TIMED`;
+- существование каждого `door.requiredSignals` и `platform.controlId` среди
+  сигналов switches/relays;
+- целостность index, уникальность ресурсов и последовательную нумерацию.
+
+Ошибка содержит путь, например:
+
+```text
+level-03.json.doors[0].requiredSignals[0] references missing signal 'missing'
+```
+
+Команда:
+
+```sh
+./gradlew :level-format:validateLevels
+```
+
+`app:preBuild` зависит от неё. Для проверки временной копии каталога можно
+передать `-PlevelDirectory=/absolute/path/to/levels`.
+
+## Детерминированный preview
+
+```sh
+./gradlew :level-format:previewLevels
+```
+
+Результат находится в `level-format/build/level-previews`:
+
+- `level-01.svg` … `level-10.svg` — world-space схема spawn/goal, платформ,
+  hazards, switches и doors;
+- `catalog.tsv` — координаты, размеры, travel и signal/control references.
+
+Вывод использует стабильный порядок и locale-independent числа. Два запуска на
+неизменном каталоге должны давать byte-identical файлы.
+
+## Bot trace
+
+Каждый generic и level-8 acceptance-run возвращает `traceJson()` и `traceId()`.
+Trace содержит:
+
+- `traceVersion`, level, `levelFormatVersion`, `physicsVersion` и scenario;
+- outcome;
+- события `START`, `INPUT`, `CHECKPOINT`, `FINISH`;
+- только simulation time, публичный input и наблюдаемое состояние игрока/дверей.
+
+Wall-clock, device identifiers и прямые mutation-команды не записываются.
+`traceId` — SHA-256 точного UTF-8 JSON и всегда включён в failure diagnostic.
+Stage 4 сохраняет воспроизводимый артефакт расследования, но намеренно не добавляет
+runtime replay executor.

+8. отсутствовала desktop-команда → validate/preview tool;
+9. preview command возвращала usage → byte-identical SVG/TSV output;
+10. отсутствовала Gradle task → validation wired before `app:preBuild`;
+11. отсутствовал versioned bot trace → deterministic Result trace + SHA-256 ID;
+12. bespoke level-8 runner не трассировался → reusable tracing driver;

+
+Результат: `BUILD SUCCESSFUL`; parser, catalog, validator, tooling, localization,

+- GREEN: intended routes 1–10, level-8 stress/recovery, level-10 delayed
+  traversal, level-5, lifecycle, restart, controls, accessibility, RU/EN,
+  onboarding/result и Stage 3 acceptance contracts.
+
+Первая попытка запуска на принудительном CPU SwiftShader была остановлена как
+неограниченная ошибка среды: эмулятор расходовал около 678% host CPU и дошёл
+только до второго теста за восемь минут. Она не содержала product failure и не
+считается RED/GREEN или retry. Финальный результат получен на стандартном
+host-rendered профиле AVD.
+
+Final APK inspection:
+
+- `unzip -t`: ошибок нет;
+- package: `com.projectsacrifice.game.debug`;
+- `versionCode=8`, `versionName=0.7.0-stage4-content-debug`;
+- `apksigner`: v1=true, v2=true, один стандартный Android Debug signer;

+- `MainActivity`: `RESUMED`, visible, reportedDrawn;
+- Android crash buffer после запуска пуст.
+
+## Внешние gates

+Как и в предыдущих этапах, automation доказывает техническую проходимость, но не
+понятность головоломок новому игроку. Bead `goon-game-human-playtest` остаётся
+открытым: требуются две независимые ручные сессии на каждый уровень.

+# Stage 5 Art Bible — Clockwork Catacombs
+
+Status: approved production direction for the Android vertical slice.
+
+## Identity
+
+The game is an original dark-comedy clockwork fantasy. Disposable volunteers are faceless brass-and-cloth constructs exploring an ancient teal-lit reliquary. Their destruction is readable and absurd, never graphic. The visual language must communicate puzzle state before decoration.
+
+This direction deliberately does not reproduce the title, knights, silhouettes, heraldry, costumes, props, level layouts, UI, animation, copy, audio, or other protected expression of *Life Goes On: Done to Death*. The shared idea is limited to the independently implemented sacrifice-puzzle mechanic.
+
+## Character rig and skins
+
+Every volunteer uses one normalized articulated rig so skins can change without changing collision or gameplay:
+
+- anchors: root, hips, chest, head, left/right shoulder, hand, knee, and foot;
+- collision remains the existing 62 x 100 gameplay rectangle and is never derived from artwork;
+- rendering may mirror the rig for facing, but anchor names and normalized bounds stay stable;
+- a skin is a palette and trim set, not a different body shape;
+- Stage 5 ships three original palettes: Brass Scout, Verdigris Keeper, and Ember Courier.
+
+The head is a round riveted lantern-mask with a single horizontal visor. The torso is a narrow boiler shell, limbs are visible rods joined by circular pivots, and a short asymmetric cloth tab supplies motion. No medieval helmet, knight crest, human face, blood, or gore is used.
+
+## Required state reads
+
+The same rig must make these states recognizable without relying on color alone:
+
+- alive idle: balanced stance, lit visor, slow boiler pulse;
+- run: alternating limb arcs and trailing cloth;
+- jump/fall: compressed or extended silhouette according to vertical velocity;
+- dead body: collapsed rotated rig with an unlit visor;
+- pinned body: rigid horizontal brace with a visible anchor bolt;
+- frozen body: squared ice shell plus intact rig silhouette and frost cracks;
+- conductive body: zig-zag arc ring plus bright joint sparks;
+- respawn: concentric assembly rings and a rising segmented silhouette.
+
+High-contrast mode must preserve outline, state icon, and value separation. Animation is decorative only: collision, switch contact, and goal detection use the existing physics objects.
+
+## Environment and hazards
+
+- platforms: ink-dark masonry faces with brass top rails and readable collision edges;
+- pressure plates and relays: one clear interaction glyph and a mechanical travel state;
+- doors: heavy portcullis frame; open/closed remains distinguishable by silhouette;
+- spikes: triangular teeth with pale edge highlights;
+- saws: toothed brass wheels with a dark hub and rotation trail;
+- freezer: cyan condenser frame and crystalline field;
+- electricity: yellow-white broken arcs with a distinct relay line;
+- pits: near-black depth with sparse teal motes, never a flat platform-colored void;
+- goal: an original suspended chronolume relic, not a crown or chalice.
+
+## UI and camera
+
+HUD panels use translucent ink surfaces, warm brass titles, pale body copy, and minimum contrast already enforced by accessibility settings. Controls remain circular and stay inside the safe viewport. Camera motion may add focus and short impact shake, but must not conceal hazards or move collision geometry. Reduced-motion mode disables shake and decorative bobbing while retaining state changes.
+
+## Animation and performance budgets
+
+- procedural rig animation is evaluated from immutable gameplay state and elapsed time;
+- at most one character rig per live volunteer and one collapsed rig per retained body;
+- no per-frame bitmap allocation, shader construction, collection growth, or text measurement;
+- particles are capped, short-lived, and may be dropped before gameplay or UI readability;
+- visual updates target 60 FPS and remain functional at the existing fixed physics cap.
+
+## Acceptance checklist
+
+- All ten levels use the same authored visual language.
+- Alive, dead, pinned, frozen, conductive, and respawning states are recognizable in grayscale screenshots.
+- At least three palette-only skins use the same normalized skeleton.
+- Art does not change geometry, timings, planned death counts, or bot routes.
+- No copied or traced commercial assets, audio, text, characters, or level dressings are present.

+# Stage 5 external playtest protocol
+
+This protocol defined the final Stage 5 acceptance gate. The owner attestation
+and evidence limitations are recorded in `STAGE5_HUMAN_PLAYTEST_RESULT.md`.
+
+## Setup
+
+- Use the immutable `0.8.0-stage5-vslice-debug` APK and record its SHA-256.
+- Recruit at least two independent participants for every level (20 sessions).
+- Do not explain controls, mechanics, level intent, or the meaning of death.
+- A participant may read only the text shown by the game.
+- Record screen/video when consent and local policy allow it; do not collect PII.
+
+## Per-session record
+
+| Field | Required value |
+|---|---|
+| Session ID | anonymous local identifier |
+| Level | 1–10 |
+| Tester cohort | new / familiar with platformers |
+| Completed | yes/no |
+| Time | seconds |
+| Volunteers | deaths retained by the result screen |
+| Restarts | count |
+| First wrong assumption | short observation |
+| Exit/softlock point | coordinates or visible object |
+| Help requested | exact question; developer still gives no answer |
+| Severity | blocker / major / minor / observation |
+| Disposition | fix / accepted / follow-up Bead |
+
+## Acceptance
+
+- 20/20 required sessions are recorded.
+- No blocker softlock is reproduced.
+- Every major observation has a fix or explicit product decision.
+- The level-balance and human-playtest Beads contain links to the evidence.
+- Only then may `goon-game-level-balance`, `goon-game-human-playtest`, and
+  `goon-game-milestone-vslice` be closed.
+
+Status on 19 August 2026: accepted by direct product-owner confirmation; raw
+session forms were not attached and no per-session data is fabricated.

+
+## Acceptance record
+
+The product owner confirmed in the project task that external testing had
+finished and explicitly directed development to proceed beyond Stage 5. This
+owner confirmation is recorded as acceptance of the external playtest and
+comprehension gate, including that no unresolved blocker prevents the next stage.
+
+Raw per-session forms, quantitative completion rates, and individual tester
+observations were not attached to the repository. Consequently this record does
+not invent participant identities, timings, death counts, or issue statistics.
+If those materials are supplied later, they must be appended without rewriting
+this attestation.
+
+Combined with the immutable candidate's automated evidence (`72` JVM tests and
+the exact Android 16 `35/35` run), the Vertical Slice milestone is accepted and
+Stage 6 may begin.

+# Stage 5 performance and determinism contract
+
+Stage 5 targets 60 FPS and requires a steady-state 30 FPS hard floor on a
+hardware-accelerated target. Cold launch/orientation time is measured separately
+from gameplay cadence.
+
+| Metric | Release ceiling |
+|---|---:|
+| p95 frame interval | 34 ms |
+| p95 simulation update | 12 ms |
+| p95 Canvas draw | 20 ms |
+| retained bodies | 16 |
+| collision checks per sampled frame | 2,500 |
+| estimated draw primitives | 2,200 |
+| used Java heap | 128 MiB |
+
+`PerformanceMonitor` keeps an allocation-free rolling window of 240 samples.
+`StageFivePerformanceTest` allows five seconds for Activity rotation and shader
+warm-up, resets the monitor, then measures ten uninterrupted seconds of level 10.
+The final Android 16 run on a 1080×2400, 60 Hz AVD using the Apple M3 Pro host GPU
+passed every ceiling.
+
+The software-only SwiftShader AVD is retained for deterministic gameplay tests,
+but is not presented as a physical-device performance result. Its measured
+steady-state p95 frame interval was 41.61 ms against the 34 ms gate. This known
+environment result is intentionally recorded rather than hidden by weakening the
+release budget.
+
+Physics uses `PhysicsConfig` version 1 and a 1/60 s deterministic automation
+step. `StageFiveDeterminismTest` records all ten state-driven routes and replays
+each exact command tape three times. Terminal/checkpoint hashes and expected
+death/body counts must match, and each complete ten-level replay pass must finish
+under five minutes.

+
+## Delivered engineering scope
+
+- Original Clockwork Catacombs art bible and a normalized articulated volunteer
+  rig with three skins and run/jump/fall/death/frozen/conductive/pinned/respawn states.
+- Procedural music, effects, and voice variants with independent persisted Music,
+  Effects, and Voice volume controls; unavailable audio degrades to silence.
+- Bounded horizontal/vertical camera damping, mechanism focus, impact shake, and
+  a persisted reduced-motion option; camera never changes physics coordinates.
+- Save version 2, safe v1 progress migration, full active-puzzle Bundle snapshot,
+  and visible-paused restore after Activity recreation.
+- Physics version 1, deterministic input tapes, terminal/checkpoint signatures,
+  and explicit runtime performance ceilings.
+
+## Automated evidence
+
+- Clean `testDebugUnitTest lintDebug assembleDebug assembleDebugAndroidTest`:
+  GREEN; 72 JVM tests in 23 classes; all 10 JSON levels validated.
+- Exact final Android 16 unfiltered run: `OK (35 tests)` in `493.521 s`.
+- The run includes all 10 production-input solutions, level 8 recovery, level 10
+  delayed decisions/body stability, restart, lifecycle, save migration/recreation,
+  RU/EN, controls, onboarding/results, audio persistence, performance, and Stage 3 regressions.
+- Determinism gate inside that run: 10 recorded routes replayed three sequential
+  times (30 completions) with matching signatures and under-five-minute pass guards.
+- Host-GPU steady-state performance gate: GREEN against every published ceiling.
+- Software SwiftShader observation: p95 frame interval 41.61 ms, above the 34 ms
+  target-device gate; documented as a non-target renderer limitation.
+- Installed APK cold-launched successfully; post-run crash/ANR buffer contained no
+  Project Sacrifice fatal exception or ANR.
+
+## Package verification
+
+- `aapt`: package/version/minSdk 23/targetSdk 34 confirmed.
+- `unzip -t`: valid APK/ZIP, no compressed-data errors.
+- `apksigner`: v1 and v2 signatures valid; one Android Debug signer.
+- This is an installable debug testing candidate, not a store-signed release.
+
+## TDD evidence highlights
+
+- Volunteer rig, audio variants/settings, camera, save codec, physics config,
+  deterministic tape, and performance monitor began with missing-contract RED tests.
+- Session restore first exposed invalid wall-clock setup and was replaced by an
+  exact fixed-step saved-state assertion before going GREEN.
+- Performance first failed on SwiftShader (`41.61 > 34 ms`); the final target gate
+  was run on hardware-accelerated Android after separating cold rotation warm-up.
+
+## Gate disposition
+
+The Stage 5 engineering release candidate is complete and reproducible. On
+19 August 2026 the product owner confirmed that external testing had completed
+and directed the project to proceed. `STAGE5_HUMAN_PLAYTEST_RESULT.md` records
+that acceptance and the absence of attached raw forms without fabricating data.
+The Vertical Slice milestone is accepted.

+Доменные EPIC продолжают отвечать на вопрос «какая система меняется», а stage —
+«в какой последовательности и каким gate работа принимается».
+
+## Контракт привязки
+
+Каждая обычная Bead, feature, bug, milestone и EPIC обязана иметь:
+
+- минимум один label `stage-N`;
+- ровно один label `primary-stage-N`;
+- metadata `primary_stage=N`, совпадающую с primary label.
+
+Дополнительные `stage-N` допустимы для сквозной работы. Primary stage определяет,
+какой gate отвечает за закрытие незавершённой задачи. Поэтому исторически начатая

+- `goon-game-content-worlds` имеет primary Stage 6 и разблокирован принятым
+  `goon-game-milestone-vslice` Stage 5.
