Since it’s a porting task, I’m keeping the review to a minimum.

CI failed

updated cache in /github/home/.ros/rosdep/sources.cache
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
autoware_path_generator: Cannot locate rosdep definition for [tier4_planning_msgs]

can we use tier4 msgs in core?

@kosuke55
In principle, we cannot use tier4's msgs in autoware.core.
The CI failure is fine for now since the AWE team is working on porting some of tier4's msgs to autoware's msgs in parallel.

PathWithLaneId has been ported. Please use it instead.
