+Stage 6 production work has started. Its three completed foundation slices add a
+deterministic character state machine, a bounded `CorpseManager`, and an
+event-driven `PuzzleSystem` with explicit signal and door transitions. The first
+mechanics slice adds data-driven crusher, fire, projectile and explosion hazards,
+teaching levels 11–14, dynamic level pagination and production-input routes.
+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.

+→ отдельным takeoff подтверждает airborne state
+→ пересекает весь flame box до приземления
+→ достигает goal, тело остаётся в уровне
+```
+
+**Контракт:** постоянный `FIRE=(700,790,120,90)` с отдельными visual/audio IDs.
+Маршрут запрещает вторую смерть на approach, takeoff и clear checkpoints.

+→ вторым прыжком проходит возвращённый снаряд
+→ добегает за spawn снаряда и достигает goal без новых смертей
+```
+
+**Контракт:** runtime вычисляет текущий box из `speedX=-400` и сбрасывает его
+на исходную позицию по `cycleSeconds=3`. Оба прыжка привязаны к snapshot
+координате, а не к wall-clock.

+
+**Контракт:** `CRUSHED` композиционно сохраняется в `CorpseManager`, уменьшает
+коллайдер и не удаляет физическую опору. Save version 3 сохраняет флаг; v1/v2
+мигрируют его в `false`. Snapshot отдельно публикует state, размеры и pressure
+capability, а Canvas добавляет текстовую метку `CRUSHED` помимо цвета.

+→ садится на неподвижный мост и пересекает PIT
+→ достигает goal на правом floor
+→ COMPLETE ровно с одной смертью и одним burned body
+```
+
+**Контракт:** `BURNED` сохраняет коллайдер, но `activatesPressure=false`; это
+проверяется одновременно состоянием тела, неактивным `firstMovingPlatformPowered`
+и нижней координатой моста. Save version 3 сохраняет флаг; Canvas добавляет
+текстовую метку `BURNED`, поэтому состояние не кодируется только цветом.

+→ COMPLETE без смерти и без создания тел
+```
+
+**Контракт:** `Player`, `CorpseManager.Body` и `PhysicalObjectState` реализуют
+один `IWeightedObject`; plate агрегирует только геометрически пересекающуюся
+активную массу, не проверяя тип. Все пять authored типов имеют type/box/mass в
+JSON, детерминированный runtime, non-color type+weight label, SVG/TSV preview и
+save-v4 состояние. V1–v3 active sessions мигрируют с пустым runtime-object list.
+
+**Bot checkpoints:** каталог публикует пять objects и Counterweight mass 3;
+до push `allDoorsOpen=false`; после push `firstPhysicalObjectX≥920` и Door open;
+после release Door остаётся open; затем два отдельных jump edge и `completed=true`.

+**Статус:** доказан production-input ботом, 3/3 последовательных прохождения.
+**Ожидаемые и доказанные смерти:** `0`; обязательный challenge-route получает
+casualty, time и collectible stars.

+→ COMPLETE с deaths=0 и time≤30 s
+→ ChallengeResult выдаёт casualty/time/collectible = true, stars=3
+→ ProgressStore сохраняет лучшие критерии по стабильному LevelID
+→ три последовательных restart-free прохождения воспроизводят 3/3 stars
+```
+
+**Контракт:** collectible является опциональным world-space объектом и сохраняется
+в active session v5. Restart сбрасывает состояние текущей попытки; завершённый
+collectible challenge накапливается в progress v3 независимо от лучших casualty и
+time runs. Legacy levels без collectible получают третью звезду за core completion.
+
+**Bot checkpoints:** `deaths=0`; после прыжка `collectibleFound=true` и
+`collectibleVisible=false`; затем `completed=true`; `CompletionResult.stars=3`,
+`bestStars=3`; новый `ProgressStore` после трёх запусков возвращает 3 звезды для
+`foundations.threefold-proof`.
+
+## 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"

+→ 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"
+→ игрок один раз касается toggle ferry x=760..832
+→ подходит к launch overlap и прыгает на platform x=940..1260
+→ snapshot подтверждает playerOnGround && playerOnMovingPlatform
+→ без input едет до platformX≥1280 и по пути забирает collectible x=1435
+→ 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"
+→ первый доброволец входит в saw x=600..696 и получает impulse (550,-700)
+→ тело попадает на raised pressure plate x=1030..1200 и открывает remote-gate
+→ следующий доброволец стартует прыжок до saw и остаётся жив
+→ 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"
+→ первый доброволец замерзает в FREEZER x=720..820
+→ следующий прыгает и стабилизируется на frozen body на y≈680
+→ отдельным jump edge поднимается на ledge x=850..1410, y=590
+→ 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"
+→ первый доброволец погибает в ELECTRIC x=720..830
+→ conductive corpse активирует relayId="living-power" и открывает Door
+→ следующий стартует прыжок до live relay
+→ 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

+→ 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`

+```
+
+**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.
+

+# Stage 6: challenges, collectibles и production progression
+
+## Принятый результат
+
+Срез добавляет стабильную идентичность уровня и три независимых production
+challenge-критерия: целевое число жертв, целевое время и collectible. Лучший
+результат накапливается между разными прохождениями и отображается как 0–3 звезды.
+
+Каталог расширен до 18 уровней. `Threefold Proof` обучает всем трём критериям на
+одном безопасном маршруте; intended route выполняется production-input ботом три
+раза подряд без teleport, прямой мутации completion или retry masking.
+
+## Контракты
+
+- `LevelDefinition.levelId` и `worldId` являются стабильными lowercase ID.
+  Legacy-контент без полей получает `legacy.level-NN` / `legacy`.
+- Optional `collectible` — world-space box. После пересечения он исчезает в текущей
+  попытке, сохраняется при Activity recreation и сбрасывается restart.
+- `ChallengeResult` независимо вычисляет casualty, time и collectible criteria.
+  На legacy-уровне без collectible третья звезда означает core completion.
+- `ProgressStore` save v3 хранит completion, лучшие deaths/time и collectible по
+  `levelId`. V1/V2 numeric keys мигрируют в ID keys без потери данных.
+- Active session v5 сохраняет `collectibleFound`; V4 и более старые snapshots
+  восстанавливаются с безопасным `false`.
+- Result UI и level cards показывают лучший star row. Complete screen сохраняет
+  Stage 3 строки Current/Best/Targets, добавляет три challenge rows и следующую
+  цель. RU/EN и non-color labels являются частью контракта.
+- SVG/TSV exporter публикует collectible и LevelID; validator проверяет ID и
+  границы collectible до упаковки APK.
+
+## TDD и найденные регрессии
+
+RED сначала зафиксировали отсутствующие `ChallengeResult`, stable IDs, JSON schema,
+ID-based persistence, session collectible, completion/UI copy, catalog level 18 и
+exporter output. Review добавил отдельный RED на duplicate stable LevelID: catalog
+loader теперь отклоняет конфликт до того, как два уровня разделят progress key.
+Каждый контракт проводился в GREEN отдельно.
+
+Первый полный Android run (`52` tests) нашёл ещё два интеграционных RED:
+
+1. Stage 3 result snapshot потерял локализованный prefix `Цели` после добавления
+   challenge rows. Prefix и видимая строка targets восстановлены.
+2. Real-time late-level driver мог пропустить узкое окно пилы уровня 10 между
+   двумя AVD polls. Late-level acceptance переведён на существующие fixed production
+   physics ticks: обычное решение принимает решения каждые 16 ms симуляции, stress
+   сохраняет 96 ms. Физика, input, collision, точные смерти и geometry не менялись.
+
+После исправления вся late-level matrix прошла `6/6`; level 10 normal выполняется
+три раза, отдельный stress route — один раз.
+
+Один предварительный повтор после нескольких непрерывных full runs получил
+environmental `frameP95=41.02 ms`; тот же неизменённый APK сразу прошёл
+изолированный 34-ms gate. Финальный exact run выполнен после cold AVD restart на
+host GPU и прошёл performance test внутри полного порядка. Бюджет не ослаблялся.

+# Stage 6 character state machine
+
+Date: 19 August 2026
+
+Beads task: `goon-game-character-states`
+
+## Contract
+
+`CharacterStateMachine` is a deterministic public model driven by the physics
+facts already owned by `GameView`: alive, grounded, velocity and facing. It
+publishes:
+
+- `IDLE`, `RUN`, `JUMP`, `FALL`, `DEATH` base states;
+- configured transient `TURN` and `LAND` states;
+- configured command states `INTERACT` and `STUNNED`;
+- priority `DEATH > STUNNED > INTERACT > locomotion`.
+
+The model does not own collision or movement and therefore does not change the
+accepted Stage 5 physics. Switch contact drives the production `INTERACT`
+transition. `STUNNED` has a public command and a tested animation contract; its
+production hazard source belongs to the Stage 6 hazards work.
+
+`PhysicsConfig` remains the single source for movement, coyote/input buffer,
+respawn and the new turn/land/interact/stunned durations. The config/level
+physics version remains `1` because no movement or collision constant changed.
+
+## Visual contract
+
+Every living state maps explicitly to a `VolunteerRig.Motion`. `TURN`, `LAND`,
+`INTERACT` and `STUNNED` change skeleton joints, so the states remain distinct
+without relying on color. Collision dimensions stay `62 x 100`.
+
+## TDD evidence
+
+Separate RED cycles covered the missing state model, airborne/death states,
+configured turn, configured land, interaction, stun priority, visual mapping,
+GameView automation integration and the regression where interaction could
+downgrade an active stun. Each RED was followed by its focused GREEN before the
+next behavior was introduced.

+## Final gates

+| 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.

+
+- 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.

+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.

+
+Date: 19 August 2026
+
+Beads task: `goon-game-corpse-manager`
+
+## Contract
+
+`CorpseManager` is the single owner of bodies in one active level. It provides:
+
+- bounded registration with stable IDs and deterministic FIFO eviction;
+- explicit remove and level-reset lifecycle operations;
+- composable `PINNED`, `FROZEN`, and `CONDUCTIVE` transformations;
+- body physics facts needed by collision, moving-platform, save, and restore code;
+- immutable lifecycle diagnostics for automation and regression tests.
+
+`GameView` remains the high-frequency physics adapter, but it no longer creates,
+owns, evicts, resets, or restores bodies through an internal collection. The
+manager exposes an unmodifiable live view, so callers can update owned body facts
+without being able to change collection membership.
+
+The body budget and FIFO policy preserve the accepted Vertical Slice behavior.
+Restart and level changes clear active bodies through the manager; save/restore
+re-registers bodies and then reapplies their stored transformations. No level
+geometry, movement, collision constant, or death signature changed.
+
+## TDD evidence
+
+Separate RED cycles covered the missing manager contract, removal/reset
+diagnostics, mutable physics facts plus composable transformations, rejection of
+foreign bodies, and the missing `GameView` automation hook. Each RED was followed
+by its focused GREEN before the next behavior was introduced.
+
+The Android integration test creates a real level-10 saw body through production
+input, verifies manager registration, restarts the level through the public game
+surface, and verifies that manager reset owns the cleanup.

+# Stage 6 production corpse states
+
+Date: 19 August 2026
+
+Beads task: `goon-game-corpse-states`
+
+## Contract
+
+The accepted `CorpseManager` transformations now include two production states:
+
+- `CRUSHED`: a pinned `140×24` solid body whose changed collider creates a low
+  step without becoming a full-height wall;
+- `BURNED`: a solid retained body that no longer contributes pressure mass.
+
+Both transformations compose with existing body ownership and pinning, have
+distinct non-color Canvas labels, are exposed through read-only automation, and
+are serialized in active-session save version 3. Legacy version 1 and version 2
+sessions migrate both flags to `false`; progress save versioning is unchanged.
+
+This is the complete set of new gameplay states approved by the GDD. `IsDestroyed`
+is a lifecycle field in the corpse data model, not a listed corpse-state variant;
+the plan does not define a separate `Shattered` state.
+
+Level 15 teaches the collider difference by requiring the crushed slab to reach
+an otherwise inaccessible ledge. Level 16 teaches the mechanism difference by
+requiring a burned body to remain on a pressure plate without powering the
+bridge above a pit. Normal, pinned, frozen and conductive states retain their
+accepted teaching routes in levels 2/3/5, 6 and 7/9/10 respectively.
+
+## TDD evidence
+
+Focused RED cycles covered the missing transformations and behavior, legacy
+codec migration, GameView state publication, catalog growth from 14 to 16, and
+both production-input scenarios. Device RED on level 16 showed a small bridge
+offset caused by the living volunteer touching the plate before death; the
+acceptance was corrected to prove the authored behavior (`powered=false` and a
+lower bridge) without requiring an impossible exact initial coordinate.
+
+The focused runtime integration test creates crushed and burned bodies through
+real level hazards. Each playthrough test runs its intended route three times,
+with no restart or direct game-state mutation, and requires exactly one death
+and one retained body.

+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.

+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

+Второй bounded authoring wave расширяет каталог с 22 до 26 уровней:

+- 23 `Remote Volunteer` — saw доставляет одно тело на поднятую pressure plate;
+- 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.

+
+## TDD и найденные ошибки
+
+RED сначала зафиксировал каталог `22 != 26`, затем отсутствие

+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,
+активирует высокий relay и только затем проходит вновь открытую Door. Retry,

+4. Level 30 срывался в PIT около `x=1800`; ferry сохранила ширину, но получила

+## Contract
+
+`PuzzleSystem` is the deterministic owner of puzzle signal channels. Each frame,
+`GameView` submits data-bound source facts and consumes published transitions:
+
+- pressure and conductive-relay sources aggregate by channel;
+- toggle and timed sources react only to their own rising contact edge;
+- timed channels expire deterministically and can be rearmed;
+- `DoorController` has an explicit `CLOSED` or `OPEN` state and ANDs its required
+  channels;
+- controlled platforms read the same channel state as doors and rendering;
+- signal and door open/close transitions are immutable frame events;
+- diagnostics expose update and transition counts without mutating gameplay.
+
+`GameView` remains the geometry adapter: it detects player/body contact and
+conductive-body overlap, but it no longer owns toggle/timer maps or calculates a
+door's required signals. Door audio and camera focus consume `DOOR_OPENED` rather
+than comparing an ad-hoc previous aggregate.
+
+The existing JSON `signalId`, `requiredSignals`, `controlId`, duration, and mass
+bindings remain unchanged. Existing content validation still rejects missing
+sources before packaging.
+
+## Lifecycle
+
+Puzzle state has an immutable snapshot containing toggle and timed channels.
+Reset clears channels, source edges, door states, events, and diagnostics. Restore
+also seeds held-source edge activity, so recreating an Activity while standing on
+a toggle or timer does not activate it a second time. Pressure and relay state is
+recomputed from restored bodies and geometry without user feedback side effects.
+
+## TDD evidence
+
+Separate RED cycles covered the missing base contract, pressure aggregation,
+timed expiry/rearm, relay plus explicit AND-door transitions, immutable
+reset/save/restore, restored held-source edges, diagnostics, and the missing
+`GameView` integration hook. Every RED was followed by its focused GREEN before
+the next behavior was added.
+
+The focused Android test completes the level-3 production-input route, leaves the
+saw body on its pressure plate, and verifies an activated signal, a published
+door-open transition, and one open `DoorController` through read-only diagnostics.

+`type`, `box`, and positive `mass`. Supported production types are `BOX`, `ROCK`,
+`BALL`, `ICE_BLOCK`, and `COUNTERWEIGHT`, matching the Beads scope. Existing JSON
+without `objects` stays source-compatible. Validation, deterministic SVG/TSV
+preview, Canvas rendering, collision/push physics, moving-platform support,
+automation and performance accounting all consume the same definitions.
+
+Active-session save version 4 stores object type, geometry, velocity, mass,
+grounding and moving-platform support. V1–v3 decode with an empty runtime object
+list; levels from those versions had no authored physical objects, so restore
+uses the level's initial definitions without inventing state.
+
+## Teaching puzzle
+
+Level 17, `The Whole Weight`, places Box(1), Rock(2), Ball(1), and IceBlock(2) on
+a pressure plate. Their total 6 cannot open the mass-9 door. The player must push
+Counterweight(3) onto the plate, release input to prove object-only retention,
+then jump across the weighted row and pass the open door.
+
+## TDD and acceptance evidence
+
+- RED: missing `IWeightedObject`/resolver and all JSON object symbols (28 compile
+  errors); GREEN: shared pure mass aggregation and five parsed types.
+- RED: missing runtime/save-v4 symbols (13 compile errors); GREEN: deterministic
+  state, corpse interface parity, v4 round-trip and v1–v3 migrations.
+- RED: catalog expected 17 but contained 16; GREEN: validator `17/17` and bounded
+  two-page pagination.
+- RED: Android scenario class absent; GREEN: compiled production-input route.
+- RED: preview lacked object geometry; GREEN: byte-stable SVG and TSV include
+  object type and mass.
+- Focused push/door/save integration: `1/1` GREEN in `9.128 s`.
+- Level 17 intended route: `3/3` GREEN in `31.119 s`, exact zero deaths/bodies.
+- Focused player/corpse/object pressure and restore matrix: `8/8` GREEN in
+  `315.926 s`.
+- Clean gate: app JVM `108/108`, content-tool JVM `2/2`, validator `17/17`,
+  lint, app APK and test APK GREEN.
+- Final exact-candidate unfiltered Android matrix: `48/48` GREEN in
+  `2,223.695 s`, with zero failures and zero skipped tests.
+- Debug APK ZIP/signature: GREEN; packaged level JSON count: `17`.
+- Debug APK SHA-256:
+  `141eecd3605d5cc5ab8ac20b52b666650b672c0723e2a3f8ea2187e75adca002`.
