Research direction

Start by reproducing the sugarcane harvest setup described: use a detector and piston to push sugarcane into a waterway, comparing the reported Paper versions with 1.21.4. Confirm whether the sugarcane is pushed or falls in place, and document the exact reproduction details, including the server's plugin and datapack list.
