SINGLE SOURCE OF TRUTH for every figure the Equity Grant Calculator (bvj-consulting) and the Portal team actions (bvj-portal, ADV-01 and Sprint G) show about advisor, early-employee and contractor grants and about Employee Incentive Plan (EIP) sizing. No page, engine or test retypes a figure from here. Every table carries its source_id, its publication date, its sample, its population and its unit, and every figure can be placed on the three axes (stage, instrument, population).
