Gripper channels are (strategy, closure), not joint angles: the last two channels of action and observation.state are normalised to the gripper's reachable travel. In action, closure = 1.0 means "drive fully closed" and the object stops the fingers; in observation.state closure stays continuous, so "am I holding something" remains observable.
The exact calibration is recorded in meta/grasp_projection.json. Decode with gripette.grasp_projection.GraspProjection — see docs/grasp_projection.md.
