Rust crate reference

LawSynth is organized as small crates with explicit contracts: lawsynth-core provides foundational validation and deterministic metadata; data, expr, world, sim, discovery, and bundle implement the executable workflow. The CLI and PyO3 extension bind that workflow for applications.

Each crate exposes a deliberately bounded offline API. Features described as unsupported in these pages are rejected or absent, not emulated by placeholder behavior.
