It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "mainstream jewel singapore" is not a specific term related to public housing or maintenance reports, and does not provide any context or information that would suggest otherwise. Therefore, the answer is "False" for the "relatedness" field, and "none" for the "type" field, with a brief explanation provided in the "explanation" field.
