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