+
+Synthetic sensors test data: 53 rows in `data.csv`.
+
+All values are randomly generated fictional examples, not real observations, products, or user activity. Intended only for CSV loading and pipeline tests; not suitable for scientific or business conclusions. Columns are sampled independently and do not model real-world correlations.
+
+## Fields
+
+- `sample_id`: random identifier for this generated sample.
+- `row_id`: sequential row number starting at 1.
+- `is_synthetic`: always true.
+- `voltage_v`, `current_ma`: simulated values in the units named in each column.
