OxigenAI 0.1.0 Released — Japan's Government Legal AI, Rebuilt in Pure Rust with Formal Verification

OxigenAI is a Pure Rust GovTech reimplementation of the Digital Agency's government legal-AI system (源内 / GenAI). It keeps the familiar law-report API but adds OxiZ SMT contradiction detection and Legalis-RS LegalResult<T> outcome classification — turning a probabilistic LLM+RAG service into a verifiable computational-law platform.

OxiHuman 0.1.2 Released — Portable, Path-Free Test Fixtures for the Client-Side Human Generator

A maintenance release for OxiHuman, the privacy-first pure Rust parametric human body generator that runs entirely client-side via WASM/WebGPU. 0.1.2 makes the MakeHuman-backed test suite fully portable — dataset and asset roots now resolve through MAKEHUMAN_DATA_DIR and OXIHUMAN_ASSETS_DIR, and fixtures skip gracefully when unset. ~943,000 lines of Rust, 32,791 passing tests, zero hard-coded paths.

OxiCode 0.2.2 Released — Dependency Hardening and Pure Rust Compression, Bumped

A focused OxiCode patch: a deny.toml policy gate to ban unsafe or incompatible crates, the bincode dev-dependency pinned to =2.0.1, OxiARC pure Rust compression bumped to 0.2.7, and more robust temp-file handling in the file-I/O test suite. Same 100% bincode-2.0 binary compatibility, same Pure Rust guarantee.
