@@ -125,15 +125,38 @@ Burned/crushed corpse states are taught in levels 15–16, level 17 adds five
 authored physical-object types over one shared pressure-mass contract, and level
 18 teaches the casualty/time/cache challenge contract with persistent three-star
 progress keyed by stable `levelId`.
+The first bounded Foundations authoring wave adds levels 19–22: a two-jump
+movement route, a two-body spike bridge, a retained pressure-door body and a
+toggle-controlled horizontal ferry. All four routes pass three consecutive runs,
+and restart clears the stateful bridge/ferry setups.
+The second wave adds levels 23–26: remote saw delivery, a frozen-body step, a
+conductive-body relay and a timed ferry with an explicit far-side recovery relay.
+Five route methods prove all four levels three times, including both the original
+timer and expired-timer recovery routes for level 26.
+The final Foundations wave adds levels 27–30: a two-body AND gate, a three-state
+body sequence with clean restart, an exact-two-death challenge and a finale that
+combines corpse bridge, pressure, toggle/timer ferry and Door. The full
+Foundations world now occupies its accepted 18–30 matrix range.
+The first Physics wave adds levels 31–34: object-held mass, a real three-object
+support stack, a saw-delivery lift route and a crusher/pressure cycle. Vertical
+object-on-object support is deterministic and covered independently from player
+movement; all four routes pass three consecutive production-input runs.

+## Уровень 19 — `First Return`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** `0`.
+
+```text
+LevelID="foundations.first-return", WorldID="foundations"
+→ игрок подходит к нижнему уступу x=650..890 и перепрыгивает его
+→ отпускает jump, подтверждает новое касание пола и создаёт второй jump edge
+→ вторым прыжком проходит высокий уступ x=1080..1380
+→ на безопасной дальней прямой забирает collectible x=1500
+→ достигает goal x=2090..2176 без смертей
+```
+
+**Контракт:** уровень повторно калибрует движение и раздельные jump edges перед
+production-комбинациями. На нём нет hazard, switch или Door; failure означает
+ошибку управления, а не скрытое состояние головоломки.
+
+## Уровень 20 — `Covered Path`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** `2`; оба тела сохраняются.
+
+```text
+LevelID="foundations.covered-path", WorldID="foundations"
+→ первый доброволец идёт в ближние spikes x=700..800 и оставляет pinned body
+→ второй прыгает с x≈520 через первое тело и погибает на spikes x=930..1030
+→ третий возвращается и одним прыжком пересекает две раздельные опоры
+→ отдельным jump edge входит на ledge x=1240..1520 и забирает collectible
+→ достигает goal с deaths=2, corpses=2
+```
+
+**Контракт:** две раздельные spike-зоны делают обе жертвы наблюдаемыми и не
+позволяют одним ранним телом случайно закрыть весь hazard. Bot fail-fast отклоняет
+третью смерть; три последовательных запуска доказывают очистку старых тел.
+
+## Уровень 21 — `Held Open`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** `1`; Door остаётся открыта телом.
+
+```text
+LevelID="foundations.held-open", WorldID="foundations"
+→ первый доброволец достигает saw x=650..742
+→ тело оседает на pressure plate x=625..785 и активирует held-gate
+→ следующий доброволец подтверждает allDoorsOpen=true
+→ начинает прыжок из рассчитанного окна x≈470 и очищает saw + retained body
+→ прыгает через collectible x=1160 до Door x=1260
+→ проходит удерживаемую Door и достигает goal с deaths=1, corpses=1
+```
+
+**Контракт:** plate и Door используют один signal ID `held-gate`. Коллекционный
+маршрут лежит внутри того же доказанного прыжка и не требует второй жертвы.
+
+## Уровень 22 — `Clockwork Step`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** `0`.
+
+```text
+LevelID="foundations.clockwork-step", WorldID="foundations"

+→ сходит на дальний floor x=1600..2500, не касаясь PIT x=1100..1600
+→ достигает goal без смерти
+```
+
+**Контракт:** toggle и moving platform разделяют signal `ferry`. Платформа имеет
+160 px launch overlap до движения и 20 px far overlap в конечной фазе; bot ждёт
+реальную поддержку, а не единичное пересечение в воздухе.
+
+## Уровень 23 — `Remote Volunteer`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** `1`; доставленное тело удерживает Door.
+
+```text
+LevelID="foundations.remote-volunteer", WorldID="foundations"

+→ перепрыгивает доставленное тело, забирает cache x=1180
+→ проходит Door x=1540..1622 и достигает goal с deaths=1, corpses=1
+```
+
+**Контракт:** дистанционно доставленное тело является единственным источником
+pressure-сигнала. Маршрут не маскирует повторную смерть и ограничен максимум одной
+жертвой на каждом шаге.
+
+## Уровень 24 — `Frozen Step`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** `1`; одно замороженное тело становится ступенью.
+
+```text
+LevelID="foundations.frozen-step", WorldID="foundations"

+→ забирает cache x=1280 и перепрыгивает на ledge x=1500..2200
+→ достигает верхнего goal с deaths=1, corpses=1
+```
+
+**Контракт:** без сохранённого frozen body высота первого уступа недостижима
+доказанным маршрутом; бот отдельно наблюдает устойчивую опору на теле.
+
+## Уровень 25 — `Living Wire`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** `1`; проводящее тело постоянно питает Door.
+
+```text
+LevelID="foundations.living-wire", WorldID="foundations"

+→ перелетает тело, забирает cache x=1100 на безопасном полу
+→ проходит Door x=1350..1434 и достигает goal с deaths=1, corpses=1
+```
+
+**Контракт:** Door открывается только живым relay-сигналом сохранённого conductive
+body; каждый шаг fail-fast запрещает вторую смерть.
+
+## Уровень 26 — `Second Hand`
+
+**Статус:** доказаны два production-input маршрута, каждый 3/3.
+**Ожидаемые и доказанные смерти:** `0` для original timer и recovery.
+
+```text
+LevelID="foundations.borrowed-time", WorldID="foundations"

+→ intended: проходит Door x=1920 на исходном таймере
+→ recovery: ждёт закрытия Door и прыгает в высокий relay x=1700,y=650 на 4 s
+→ оба маршрута поднимаются на ledge x=2230..2700, забирают cache x=2350
+→ достигают верхнего goal без смерти
+```
+
+**Контракт:** recovery relay использует тот же `second-hand`, но расположен над
+обычным беговым маршрутом. Отдельный тест сначала наблюдает реально закрытую Door,
+затем её повторное открытие — softlock после истечения исходного таймера исключён.
+
+## Уровень 27 — `Two Keys`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** `2`; AND-door требует оба сохранённых тела.
+
+```text
+LevelID="foundations.two-keys", WorldID="foundations"
+→ первый доброволец погибает на SPIKES x=620..720
+→ pinned body пересекает pressure x=600..740 и даёт weight-key
+→ второй перепрыгивает pressure body и погибает в ELECTRIC x=1050..1160
+→ conductive body даёт wire-key; только теперь Door x=1540 открыта
+→ третий двумя отдельными jump edge очищает оба тела, забирает cache x=1320
+→ проходит AND-door и достигает goal с deaths=2, corpses=2
+```
+
+**Контракт:** после первой смерти Door явно остаётся закрытой; после второй бот
+наблюдает `allDoorsOpen=true`. Любая третья смерть немедленно завершает маршрут.
+
+## Уровень 28 — `Clean Restart`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения;
+после третьего запуска отдельный restart очищает попытку.
+**Ожидаемые и доказанные смерти:** `3` — saw, freezer, electric.
+
+```text
+LevelID="foundations.clean-restart", WorldID="foundations"
+→ saw x=600 доставляет первое тело impulse (500,-700)
+→ второй доброволец очищает saw/доставленное тело и замерзает в x=1250..1350
+→ третий очищает saw и frozen body, затем погибает в ELECTRIC x=1700..1810
+→ четвёртый отдельными jump edge очищает все три сохранённых тела
+→ забирает cache x=2180 и достигает goal с deaths=3, corpses=3
+→ restart возвращает spawn, deaths/corpses/cache/input/time в чистое состояние
+```
+
+**Контракт:** маршрут демонстрирует три разных состояния тел в одной попытке;
+restart проверяется через публичный automation boundary без прямой очистки runtime.
+
+## Уровень 29 — `Minimum Cost`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** ровно `2`, совпадает с challenge target.
+
+```text
+LevelID="foundations.minimum-cost", WorldID="foundations"
+→ первый доброволец закрывает SPIKES x=700..800
+→ второй через первое тело достигает SPIKES x=930..1030
+→ второе pinned body одновременно закрывает шипы и удерживает minimum-weight
+→ третий пересекает оба тела и касается TIMED x=1190 на 10 s
+→ weight + minimum-clock открывают Door x=1510
+→ игрок забирает cache x=1360 и достигает goal без третьей смерти
+```
+
+**Контракт:** challenge route fail-fast ограничен двумя жертвами; Door до TIMED
+switch остаётся закрытой, поэтому давление нельзя обойти простым прыжком.
+
+## Уровень 30 — `Foundation Relay`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** ровно `3`; это finale мира Foundations.
+
+```text
+LevelID="foundations.foundation-final", WorldID="foundations"
+→ два добровольца раздельно закрывают SPIKES x=550 и x=800
+→ третий пересекает corpse bridge и погибает на saw x=1130
+→ saw body оседает на pressure x=1100..1260 и удерживает finale-weight
+→ четвёртый пересекает мост и pressure body, включает TOGGLE finale-ferry
+→ TIMED finale-clock на 18 s открывает Door вместе с retained pressure body
+→ игрок садится на ferry x=1570..1930, едет до platformX≥1950 над PIT
+→ прыгает на far floor x=2300, забирает cache x=2450
+→ проходит Door x=2610 и завершает мир с deaths=3, corpses=3
+```
+
+**Контракт:** finale не вводит новой механики. Оно последовательно проверяет
+corpse bridge, pressure, toggle-controlled ferry, timed AND-door и collectible;
+каждая смерть и реальная опора на moving platform наблюдаются ботом.
+
+## Уровень 31 — `Weight Class`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения;
+после них restart возвращает сдвинутый объект и Door в исходное состояние.
+**Ожидаемые и доказанные смерти:** `0`.
+
+```text
+LevelID="physics.mass-basics", WorldID="physics"
+→ игрок толкает COUNTERWEIGHT mass=3 с x=650 на pressure x=940..1190
+→ requiredMass=3 открывает mass-door без присутствия игрока на плите
+→ input отпускается, Door остаётся открытой только массой объекта
+→ игрок перепрыгивает противовес, забирает cache x=1580
+→ проходит Door x=1370 и достигает goal без смертей
+→ restart возвращает object x=650,y=780, закрытую Door и чистый input/cache
+```
+
+**Контракт:** это первый production-уровень Physics и отдельное обучение
+`weighted-object`; pressure resolver не различает player/corpse/object по типу.
+
+## Уровень 32 — `Stack Order`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** `0`.
+
+```text
+LevelID="physics.stack-order", WorldID="physics"
+→ BOX x=650,y=800 поддерживает ROCK x=700,y=720
+→ ROCK поддерживает ICE_BLOCK x=760,y=640; solver сохраняет обе опоры
+→ игрок отдельными jump edge поднимается на нижний и верхний объекты
+→ со стопки прыгает на gallery x=1030,y=600 и забирает cache x=900,y=555
+→ по верхней галерее достигает goal x=2260,y=490 без смертей
+```
+
+**Контракт:** vertical object/object contact выбирает первую пересечённую опору
+снизу, не телепортирует восходящие или не пересекающиеся объекты и не меняет
+существующую player physics.
+
+## Уровень 33 — `Launch Window`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** `1`; saw launch сохраняет одно тело.
+
+```text
+LevelID="physics.launch-window", WorldID="physics"
+→ первый доброволец входит в saw x=600 и получает impulse (700,-420)
+→ следующий начинает прыжок до saw и отдельным edge очищает доставленное тело
+→ у нижней фазы садится на lift x=1350,y≈790
+→ snapshot подтверждает реальную moving-platform support
+→ едет до y≤430 и прыгает на gallery x=1750,y=500
+→ забирает cache x=2050 и достигает верхнего goal с deaths=1, corpses=1
+```
+
+**Контракт:** уровень сочетает уже обученный saw-launch с вертикальной движущейся
+опорой; бот наблюдает смерть, доставленное тело, посадку и верхнюю фазу отдельно.
+
+## Уровень 34 — `Press Cycle`
+
+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** `1`; crushed body сохраняется на pressure.
+
+```text
+LevelID="physics.crusher-rhythm", WorldID="physics"
+→ первый доброволец погибает в CRUSHER x=680..850
+→ crushed body становится низкой retained mass на pressure x=650..880
+→ следующий наблюдает active и inactive фазы полного 4.5 s цикла
+→ одним новым jump edge пересекает resting press без второй смерти
+→ забирает cache x=1320 и достигает goal с deaths=1, corpses=1
+```
+
+**Контракт:** pressure фиксирует результат жертвы, а timing остаётся обязательным:
+каждый шаг fail-fast отклоняет вторую смерть и не перезапускает цикл.

+collision checks and draw primitives. Emulator detection is explicit and does
+not change `PerformanceBudget.release()` or the physical-device contract.

 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

+but is not presented as a physical-device performance result. Host scheduling

+# Stage 6: production content matrix
+
+## Принятый объём
+
+Production-релиз зафиксирован на `69` уровнях. Уровни 1–17 сохраняются как
+принятый vertical-slice и mechanics workshop; уровни 18–69 образуют четыре
+production-мира по 13 уровней:
+
+| Мир | Диапазон | MAIN | CHALLENGE | FINALE |
+|---|---:|---:|---:|---:|
+| Foundations | 18–30 | 11 | 1 | 1 |
+| Physics | 31–43 | 11 | 1 | 1 |
+| States | 44–56 | 11 | 1 | 1 |
+| Mastery | 57–69 | 11 | 1 | 1 |
+
+В каждом мире challenge идёт предпоследним, finale — последним. Challenge и
+finale не вводят новую механику: они проверяют уже обученные комбинации. Level 18
+`foundations.threefold-proof` является первым production-слотом и уже принят как
+обучение casualty/time/collectible challenges.
+
+## Исполняемый контракт
+
+Источник плана —
+`level-format/src/main/resources/content/production-content-matrix.tsv`. Каждая
+строка фиксирует:
+
+- последовательный номер, стабильные `worldId` и `levelId`;
+- роль `MAIN`, `CHALLENGE` или `FINALE`;
+- английское имя и единственную вводимую механику либо `-`;
+- полный набор используемых механик;
+- casualty/time targets и обязательный collectible.
+
+`ProductionContentMatrix` отклоняет каталог до сборки Android, если:
+
+- уровней не 52, номера не образуют непрерывный диапазон 18–69 или ID повторяются;
+- нарушены порядок миров, размер мира или позиции challenge/finale;
+- stable LevelID не принадлежит своему world, новая механика не используется
+  самим teaching-уровнем либо вводится в challenge/finale;
+- отсутствует challenge target или collectible;
+- уже авторизованный JSON-уровень расходится с планом по ID, world, title,
+  targets или collectible.
+
+Команда ручной проверки:
+
+```sh
+./gradlew :level-format:validateContentMatrix
+```
+
+Android `preBuild` зависит от этого gate. Текущее ожидаемое сообщение:
+
+```text
+Validated production content matrix: worlds=4; planned=52; authored=17; releaseTotal=69
+```
+
+## Content pipeline и Level DoD
+
+Матрица разрешает авторинг, но не принимает greybox автоматически. Каждый новый
+JSON-уровень добавляется только ведущим префиксом и проходит:
+
+1. concept и solution graph;
+2. greybox с зарегистрированным stable LevelID;
+3. JSON validator и matrix-prefix validator;
+4. production-input bot без teleport/retry masking;
+5. restart, blocker-softlock и collectible/challenge проверки;
+6. camera, sound, art, optimization и QA regression gates из Level DoD.
+
+Foundations 18–30 и Physics 31–34 полностью авторизованы через этот pipeline.
+Следующий bounded slice — Physics 35–38; незавершённый уровень не скрывается в
+общем счётчике production-контента.
+
+## TDD и текущий gate
+
+RED сначала зафиксировал отсутствующий `ProductionContentMatrix` (15 compile
+errors), затем отсутствующую CLI-команду `validate-matrix` (exit `2`). После GREEN
+добавлен отрицательный regression: изменение planned title Level 18 отклоняется
+как drift реального JSON-префикса.
+

+Первый authoring wave расширяет каталог с 18 до 22 уровней и реализует четыре
+последовательные строки executable content matrix:
+
+- 19 `First Return` — два раздельных jump edge, `0` смертей;
+- 20 `Covered Path` — две spike-зоны, ровно `2` тела-моста;
+- 21 `Held Open` — одно тело удерживает pressure Door;
+- 22 `Clockwork Step` — toggle включает горизонтальную ferry platform над PIT.
+
+Каждый уровень имеет RU/EN copy, stable LevelID/WorldID, casualty/time targets,
+collectible, solution graph и state-driven production-input route. Четыре route
+methods выполняют по три последовательных запуска без teleport, прямой мутации
+completion или retry masking.
+
+## TDD и найденные ошибки
+
+RED контракты сначала зафиксировали каталог `18 != 22` и отсутствующие четыре
+`FoundationsScenarios`. Первый device run затем дал четыре независимых RED:
+
+1. Level 19 прошёл мимо слишком высокого cache (`x=1949.1761`, deaths `0`).
+   Cache перенесён на безопасную дальнюю прямую после двух обязательных прыжков.
+2. Level 20 одним прыжком пропускал требуемое второе тело (`deaths=1`,
+   firstCorpseX `641.8331`). Один широкий strip разделён на две spike-зоны.
+3. Level 21 повторно касался дальнего края saw (`x=734.3325`, deaths `2`).
+   Takeoff зафиксирован в рассчитанном окне `x≈470`; physics/saw не менялись.
+4. Level 22 терял ferry до стабильной посадки (`x=1215.3331`, deaths `1`).
+   Toggle перенесён к launch zone, ferry получила достаточный стартовый overlap,
+   а bot подтверждает `playerOnGround && playerOnMovingPlatform`.
+
+После GREEN отдельный restart test доказал, что user restart Level 20 удаляет
+тело/смерть/held input, а Level 22 сбрасывает toggle, platform motion,
+collectible и input. Первый unfiltered run нашёл один acceptance drift: каталог
+теперь имеет три страницы, а тест ожидал две. UI-контракт обновлён на страницы
+1–3 и повторный cold run прошёл полностью.

+- 24 `Frozen Step` — одно frozen body становится обязательной ступенью;
+- 25 `Living Wire` — одно conductive body постоянно питает relay и Door;
+- 26 `Second Hand` — timed ferry над PIT и высокий far-side recovery relay.
+
+Имя Level 26 изменено с дублирующего `Borrowed Time` на уникальное `Second Hand`;
+stable ID `foundations.borrowed-time` сохранён, поэтому identity и будущие saves
+не зависят от редактируемого display title.
+
+Все уровни имеют RU/EN copy, stable LevelID/WorldID, casualty/time targets,

+
+## TDD и найденные ошибки

+контента и choreography:
+
+1. Level 23 останавливался перед raised platform (`x=838`); подход к обязательному
+   прыжку перенесён раньше без изменения saw/physics.
+2. Level 25 проходил ниже слишком высокого cache; cache перенесён на доказанный
+   безопасный ground route.
+3. Оба маршрута Level 26 падали в PIT около `x=1128`; TIMED switch перенесён к
+   launch zone, а ferry получила достаточный boarding overlap и state-driven
+   launch policy.
+4. После пересечения PIT Level 26 проходил под cache (`x=2638`); финальный путь
+   разделён на наблюдаемую посадку на верхний ledge и отдельный сбор cache, а
+   ledge сдвинут так, чтобы требовать этот подъём.
+
+Финальный focused suite прошёл `5/5` methods — `15` route executions за
+`10.768 s`. Recovery route трижды ждёт `allDoorsOpen=false` на дальней стороне,

+
+## TDD и исправления контента
+
+RED сначала зафиксировал каталог `26 != 30`, затем отсутствие

+
+1. Level 27 имел два тела, но pressure body не пересекал plate; plate приведена к

+2. Level 28 повторно касался delivery saw после respawn; каждый повторный переход
+   разделён на approach, наблюдаемый takeoff, clear saw и новый jump over body.
+3. Level 29 получал третью смерть на дальних spikes; использована доказанная
+   геометрия двух раздельных spike bodies и отдельный release/new jump edge.
+4. Level 30 срывался в PIT около `x=1800`; ferry сохранила ширину, но получила
+   минимальный достаточный travel `400` вместо избыточного `630`, а бот ждёт
+   реальную grounded support до far launch phase.
+
+Повторный targeted run прошёл `4/4` methods, `12` routes и clean restart.

+## Late-load regression
+
+Первый cold unfiltered run завершился `66 tests, 3 failed` за `1h28m35s` и
+обнаружил не контентные, а инфраструктурные late-load проблемы:
+
+- `GameRestartTest` использовал host deadline и дошёл лишь до `x=364`, не создавая
+  первое тело;
+- fire route использовал `Thread.sleep`, повторно погиб у `x=642`;
+- frame interval AVD включал external host scheduling (`p95=175.65 ms`), хотя
+  update/draw/memory/complexity не нарушали budget.
+
+Restart и hazard drivers переведены на публичный deterministic automation clock.
+Performance gate выполняется до тяжёлых playthrough. На AVD он строго проверяет
+180+ samples, p95 update/draw, memory, bodies, collision checks и draw primitives;
+AVD frame interval публикуется, но не подменяет физическое устройство, потому что
+делит scheduler с host. На physical hardware полный `PerformanceBudget.within`,
