It seems that the Twitter post "cave singapore" does not relate to a maintenance report feedback to public flat house. It is not a specific issue or complaint about a facility, inconvenience, block number, or street, and does not request fixing or resolution of any kind. Therefore, the answer is "relatedness": False, "type": "none", and "explanation": "This is not related to public housing or maintenance report feedback."
