One measure, one contract
This profile documents one bounded indicator at a time. Its ranks, distributions, histories, and paired views remain inside the stated universe, period basis, source, unit, and methodology; they are descriptive research screens, not legal findings or components of a composite score.
CR4 is the sum of the four largest sourced participant shares or a source-reported aggregate CR4 in each released anchor. Different market definitions and measurement bases remain non-interchangeable.
