It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house. The post simply mentions "greenbook" without any context or information that would suggest otherwise. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not possible to determine the type of feedback or issue being discussed. The "explanation" field contains a brief explanation of why the post does not relate to the requested topic.
