It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house. The post mentions "challenge accepted" and "merlion park," but there is no mention of any specific issue or facility related to public housing. Therefore, the answer is "relatedness": False and "type": "none."
