    "documented_disagreement": [
        "A violation being recorded as open does not mean the condition still exists. HPD states that a violation closes only when HPD verifies correction or the owner certifies it as corrected, so an open violation may describe a condition already fixed but not certified. Counts of open violations circulate widely as a measure of current housing conditions and overstate it for this reason."
