    "content": "Across the 422,729 rows in `raw.semi_conductor_se`, the categorical columns have very different cardinalities. The figures come from the distinct-count query already run.\n\n- **company_name**: 152 distinct values\n- **stock_name**: 152 distinct values\n- **_batch_id**: 1 distinct value\n- **_source_file**: 1 distinct value\n- **_source_system**: 1 distinct value\n\n**Interpretation:**\n- `company_name` and `stock_name` both have 152 distinct values, which suggests a one-to-one mapping between company and ticker/stock. I did not verify that mapping directly.\n- The 152 here is slightly higher than the ~149 shown on the dataset card. The card figure is approximate, so I treat the exact count of 152 as authoritative.\n- The three ingestion-metadata columns (`_batch_id`, `_source_file`, `_source_system`) each have a single value. The whole table was loaded in one batch from one file and system, so these columns carry no analytical signal.\n- The only real classifier for analysis is the company/stock identifier, with 152 entities.\n\nThe result is one summary row, so there is no breakdown to chart."
