Funder-Fit Engine — Org-Anchored Corpora and the Bidirectional Story↔Funder Cycle

Fundraising is a two-way match: understand a funder and build a story that answers them, or take a committed story and find the funders it unlocks. Both directions run on one substrate — a trustworthy, per-organization corpus. This maps the path to that engine, and argues the differentiator is KAG (graph-grounded), not plain RAG, because we just built the graph.
