Towards an Open Architecture for LDL

Summary: Extends LDL with bidirectional calls between logic programs and external procedures, treating externals as infinite relations to retain standard logic-program semantics. Adds safety conditions, optimization costs, and interfaces for complex objects and multiple answers. (summarized by gpt-5.6-luna on Jul 24 2026)
