It seems that the Twitter post "legacy singapore" does not relate to a maintenance report feedback to public flat house. The post does not mention any specific issues or concerns related to public housing, such as broken facilities, inconveniences, or requests for repairs. Therefore, the answer is "relatedness": False, and the type is "none".
