Show HN: Lean4 Datalog DSL Based on Google Zanzibar for AI Projects

A developer has created ZIL, a domain-specific language (DSL) built on Lean 4 that implements Google's Zanzibar authorization model for managing relationships between code declarations, requirements, documents, and project artifacts. The tool allows developers, AI assistants, and CI systems to query a unified project map to answer questions like which code implements specific requirements or which modules depend on particular declarations. ZIL uses a relational tuple model (subject—relation—object) inspired by Zanzibar's authorization system to track and reason about complex project dependencies and relationships.
