Capability Gap Index (CGI) — Embedding-Distance Indicator for Procurement Matching (Spec Pack, Restricted)

This restricted spec pack defines a Capability Gap Index (CGI): a compact, auditable indicator that quantifies the semantic distance between procurement requirements and supplier capability evidence using normalized embedding-space geometry (angular distance). It includes formal scoring variants, evidence-weighting, uncertainty reporting, evaluation scaffolding, and minimal integration contracts. The package is intended for internal assessment, governance review, and licensing discussions; it is not an implementation manual and avoids disclosure of proprietary operational details.
