## `lsdtools.physics.KINEMATIC_TARGET_POSITION_LIMIT`

Kind: value. Source: `services/physics/src/lsd_physics/timeline.py:13`.

```python
KINEMATIC_TARGET_POSITION_LIMIT = 1000000.0
```


Implementation alias: `lsd_physics.timeline.KINEMATIC_TARGET_POSITION_LIMIT`.

## `lsdtools.physics.PhysicsTimelineProvider`

Kind: class. Source: `services/physics/src/lsd_physics/timeline.py:121`.

```python
PhysicsTimelineProvider(self, context: Any) -> None
```


Source docstring:

```text
Stateless adapter to bounded kinematic translation controls.

Targets are scene object EIDs, never physics row numbers or native body IDs.
The initial slice retains orientation and refuses angular velocity and actor
control on the target. It does not expose arbitrary pose or dynamic-body edits.
```


Implementation alias: `lsd_physics.timeline.PhysicsTimelineProvider`.
