# Type Catalog This directory contains the first Railiance Fabric type catalog. - `capability-types.yaml` defines stable semantic capabilities. - `interface-types.yaml` defines concrete integration surfaces. Declaration schemas keep `capability_type` and `interface_type` as strings so the core document shape stays decoupled from catalog evolution. The validator planned in `RAIL-FAB-WP-0001-T05` should load these catalogs and reject unknown types unless an explicit experimental override is added later.
