It seems that the Twitter post "sky morning" does not relate to a maintenance report feedback to a 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", "explanation": "This is not related to public housing or maintenance issues." }
