The given Twitter post does not seem to be related to a maintenance report feedback for a public flat house. The post compares two types of chips (i7 and i5) and mentions a specific location (Bukit Panjang, Singapore), but it does not contain any information related to maintenance or infrastructure issues in a public flat house. Therefore, the answer is "relatedness": False and "type": "none".
