Definition. Entity-Adjusted 90D Coin Days Destroyed (eCDD-90) is the 90-day rolling sum of Coin Days Destroyed (CDD), with transactions between addresses controlled by the same network participant discarded and the result normalized by time to account for the increasing destructible-coin-age baseline.

Technical. Same-entity reshuffles are filtered at the daily layer using account-based clustering before the 90-day rolling sum is taken. Time normalization adjusts for the secular drift in the destructible coin-age inventory as the network ages.
