Create an interface

Interfaces are reusable semantic contracts that let multiple object types share behavior and structure.

Current request shape

Based on CreateInterfaceRequest, OpenFoundry currently supports:

Field	Required	Purpose
name	yes	stable interface identifier
display_name	no	user-facing label
description	no	semantic purpose

Current creation flow

designer
  -> POST /api/v1/ontology/interfaces
  -> ontology-service persists ontology_interfaces row
  -> owner_id comes from authenticated subject
  -> interface becomes available for interface-property authoring and type binding

Why this matters

Interfaces let OpenFoundry express repeatable concepts like reviewable, schedulable, or geo-locatable without duplicating property design across many object types.
