It seems that the post does not mention anything related to maintenance report feedback for a public flat house in Singapore. The phrase "gateway oblivion" and "singapore singapura" do not provide any context or clues that suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
