-This package provides a minimal, well-typed scaffold for a federated optimization
-stack used in CosmosMesh MVP initiatives. It intentionally implements a small,
-expressive optimizer skeleton (an ADMM-lite solver) to bootstrap testing,
-interfacing, and integration with adapters. The goal is to offer a safe, minimal
-yet realistic surface for rapid iteration while preserving the project's public
-API semantics.
+Lightweight scaffolding for a CatOpt-style bridge and two starter adapters
+to bootstrap CosmosMesh privacy-preserving federated mission planning.
