It seems that the Twitter post you provided does not mention anything related to a maintenance report feedback for a public flat house in Singapore. The post simply mentions "jalan besar sport center gym singapore" which does not provide any context or information related to maintenance reports or public flats. Therefore, the answer is "relatedness": False, "type": "none", and "explanation": "This post does not relate to a maintenance report feedback for a public flat house."
