It seems that the Twitter post "red beacon red singapore" does not relate to a maintenance report feedback to a public flat house. The post does not mention any specific issue or facility related to public housing, and does not appear to be a complaint or feedback of any kind. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not possible to determine the type of feedback or issue being mentioned in the post. The "explanation" field is left blank since there is no explanation for why the post is not related to maintenance reports.
