she travelled with the Doctor in the TARDIS (in Journey's End), together they helped save the world and piloted it back home. i dont think it matter in the slightest if it was a short adventure - in that moment she was a companion of the Doctor's.

"So bringing up a spinoff is not obvious cause to move her across categories."

as i have said, Kazran was upgraded for his appearance in an audio story (thus making him a multi-story companion) so i dont think it matters at all if it was a spin-off or not. and, while it may have been Sarah's show, she was still a companion of the Doctor in that episode (just like Jo / Sarah are on the Eleventh Doctor's list because of Death of the Doctor). and once again travelled in the TARDIS with him.
