    "reasoning": "Student_ID has Uniqueness 1.000 (4,500 distinct values across 4,500 rows), so each row is one distinct student. The table has no event timestamp or sequence column; the only datetime is the _ingestion_timestamp provenance column, which is ignored. The remaining columns are demographics and one-off survey measurements (Age, Gender, Daily_Usage_Hours, Sleep_Duration_Hours, Mental_Health_Index, GPA). With no repeated entity, no time axis and no lifecycle columns, the table is a dimension."
