EKF — Eidos Knowledge Format package contract.
EKF is the package boundary around Eidos, not the runtime graph. It declares partitions, source roots, policies, gates, and artifact layout. Eidos still computes the graph, retrieval confidence, trust tiers, and receipts.
This crate intentionally parses only the small v0.1 manifest subset Eidos consumes today. Unsupported or malformed structure becomes diagnostics instead of implicit behavior.
