+
+**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.

 1. Сохранять полный integrated device-regression: intended route принятых уровней по три раза и отдельный recovery route уровня 8.

+# Stage 6: Foundations wave 2
+
+## Принятый результат
+
+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.
+
+Все уровни имеют RU/EN copy, stable LevelID/WorldID, casualty/time targets,
+collectible и solution graph. Пять Android methods выполняют по три
+последовательных production-input route: по одному для Levels 23–25 и два для
+Level 26 — исходный таймер и восстановление после его истечения.
+
+## TDD и найденные ошибки
+
+RED сначала зафиксировал каталог `22 != 26`, затем отсутствие
+`AdvancedFoundationsScenarios`. Device-прогоны обнаружили конкретные 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,
+активирует высокий relay и только затем проходит вновь открытую Door. Retry,
+teleport и прямая мутация completion отсутствуют.
+
+## Level DoD evidence
+
+- JSON validator: `26` levels, format/physics version `1`;
+- content matrix: `4` worlds, `52` planned, `9` authored production rows,
+  release total `69`;
+- focused routes: `5/5` methods, `15` playthroughs, `10.768 s`;
+- app JVM: `118/118`; level-format JVM: `7/7`;
+- clean `lintDebug`, app APK и AndroidTest APK: GREEN;
+- final cold unfiltered Android 16: `62/62`, failures/errors `0/0`,
+  instrumentation time `1063.114 s` (`BUILD SUCCESSFUL` in `17m55s`);
+- APK ZIP: no errors; `26` level JSON packaged;
+- debug APK SHA-256:
+  `67510d404cfa0704500cbf36c7845e9ba9fa05e96630079ab02bc35113e946fa`.
+
+Wave не меняет глобальную physics/runtime модель. Следующий bounded slice —
+Foundations 27–30, включая challenge и finale этого мира.
