2. feat(port): move vehicles in elevator #3151 was made without header inclusion in refactor: extract to vehicle_part.h #3104 since it wasn't merged yet
3. feat(port): move vehicles in elevator #3151 got merged first, with all tests passing
4. refactor: extract to vehicle_part.h #3104 got merged later, with all tests passing, however it was a lie! the source code changed after merging feat(port): move vehicles in elevator #3151, but no additional tests were ran on refactor: extract to vehicle_part.h #3104
