It seems that the Twitter post does not relate to a maintenance report feedback for a public flat house. The post mentions a happy arts vegetarian cafe in Singapore, but it does not mention any issues or concerns related to maintenance or public housing. Therefore, the answer is a JSON object with a "relatedness" of False, a "type" of "none", and an "explanation" of a short reason why the post is not related to the requested topic.
