It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house. The term "giant hyperfresh" is not a common term used in the context of public housing or maintenance reports, and it does not provide any specific information or context that would suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
