It seems that the post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The term "working pink terrain" is not a common term used in the context of maintenance reports, and it does not provide any information about a specific issue or facility that needs attention. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
