It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The post simply mentions the National Library Building in Singapore, which is likely a public library or cultural institution. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because it is not related to any specific category. The "explanation" field provides a brief explanation for why the post does not match the given criteria.
