It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The term "mangrove boardwalk" is likely referring to a recreational area or a tourist attraction, rather than a maintenance issue in a public housing estate. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not related to any specific category. The "explanation" field provides a brief explanation for why the post is not related to the requested topic.
