A situation came up with grappling struts in a game the other day, and we didn't know how to rule it.
A vulture was at range 0 of debris with struts open. It revealed a 2 right turn, and rotated. By rotating its base was no longer on the debris. At that point is the ship considered on the debris still? It technically didn't move and should still be at range 0 of the debris, however, because the bases aren't perfectly square it was no longer on the debris.
FYI it was a casual game, and we played it as the ship was no longer on the debris, with the struts open.
