    "content": "**Size:** The dataset has a single table, `raw.iris`, with **150 rows** and **9 columns**. Four are numeric measurements (`sepal_length`, `sepal_width`, `petal_length`, `petal_width`). One is the `species` label. Four are ingestion metadata columns (`_ingestion_timestamp`, `_batch_id`, `_source_file`, `_source_system`).\n\n**Time period:** The dataset covers no real time period. The measurements are one row per iris specimen, with no date or time field describing when each flower was measured. The only temporal column is `_ingestion_timestamp`, which records when the data was loaded, not when it was observed. The query shows all 150 rows were ingested at a single instant, 2026-09-30 06:33:56.923935. They came from 1 batch and 1 source file. Time-based trends are therefore not possible with this data."
