It seems that the Twitter post "cave singapore" does not relate to a maintenance report feedback to public flat house. It is not clear what the post is referring to, as it is a generic term and does not provide any context or information related to maintenance reports or public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because it is not possible to determine the type of the post based on the provided text. The "explanation" field is left blank because there is no additional information to provide.
