It seems that the provided Twitter post does not mention anything related to maintenance report feedback for a public flat house in Singapore. The post simply mentions the name of a restaurant, "royal pratas curries orchard singapore", which does not relate to any maintenance issue or feedback for a public flat house. Therefore, the answer is a JSON object with "relatedness" set to False, "type" set to "none", and "explanation" set to a short explanation that the post does not relate to the requested topic.
