fundraising review board

Cohort drift stays tied to the fundraising motion that owns it.

The cohort lane keeps expected versus actual retention, upgrade, recency, and stewardship gaps on one route so teams can review where donor health is softening before the next appeal cycle.

Synthetic demonstration data only. This repo models fundraising cohort risk and does not contain real donor or nonprofit CRM records.
