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 "green signature Singapore" is not a specific term related to public housing or maintenance reports, and it does not provide any context or details 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 related to any specific category. The "explanation" field provides a brief explanation for why the post is not related to the requested topic.
