    "reasoning": "The entity is stock_name (152 unique, mirrored by company_name; RPUV 2781) and it repeats along the daily axis date (3,537 unique, monotonicity 1.000). Each row is a clock-driven observation of absolute measured values (open/high/low/close/volume) for one stock on one trading day, not a change or delta. Coverage is near-complete: the top three stocks have 3,475 rows each, and several dates have all 152 stocks. That means a stock-by-day snapshot → state. _unnamed_0 is just a row index, and the provenance columns are ignored."
