fix(experement): honest collision poses, mandatory lifts, rest-to-rest waits; 20/20 verified

- forbid the transport pose; recovery reconfigures through work only
- mandatory axial lift after every contact (handoff, tighten, dock, pick)
- untwist the flange after simulated tightening so joint 7 never winds up
- attach carried tool/cap/screw to the MoveIt scene; explicit REMOVE diffs
- add_world receives box-centre poses (placed_cap_pose, restore_world)
- table top lowered below the base_link collision mesh bottom (1 mm gap bug)
- 1 mm clearances for cap/screw boxes; thinner cap world box (cup clearance)
- wait for a stationary arm before every planning attempt (rest-to-rest)
- loosen stopped_velocity_tolerance to 0.08 for reference launches only
- retry a rejected named move once after settling (startup telemetry race)
- adapter logs the exact reason and max joint velocity on start-state rejects
- verified: all 20 experiments completed in Webots execute mode (10.11.2026)

 - Прикреплённые объекты MoveIt моделируются: захваченные инструмент, люк и
   винт переносятся из мировой сцены в `attached_collision_objects` с
   разрешённым контактом звеньев `tcp`, `patron`, `link7` и держателя камеры.
-  Если в установленной версии MoveItPy снова появятся ложные касания,
-  первым делом проверяются touch-звенья и габариты боксов в `geometry.yaml`.
+  Прикреплённые боксы люка и винта укорочены так, чтобы на позе захвата их

+  с нулевым зазором считается контактом стартового состояния и блокирует
+  обязательный осевой подъём.
+- Поза бокса при возврате объекта в мир — это поза **центра бокса** с
+  плоской yaw-ориентацией (конвенция `build_world_objects`), а не поза узла
+  OBJ с поворотом Rx90. Док инструмента и восстановление винта/люка после
+  имитированного срыва используют `bridge.restore_world` с калиброванной
+  начальной позой; поставленный люк добавляется через `placed_cap_pose`.
+  Нарушение этой конвенции было причиной «ложных столкновений» (поставленный
+  люк становился вертикальной плитой, задокованный инструмент — лежачим).
 - MoveIt/MoveItPy может аварийно завершиться после очень длинной серии
   планирований; один запуск выполняет один опыт, поэтому серия ограничена.
