OpenXR: VR / AR runtime with desktop fallback
Git4D: Time, Author, Branch, and Path intelligence

Preserved advantages

Custom capability on the official path.

GPT-5.6 provider intelligence

Built-in Bedrock model IDs and provider fallback keep the newest model family available to app-server sessions.

Ollama without a second workflow

Local model discovery, automatic readiness, and Responses API compatibility sit behind the same CLI and TUI.

Git4D spatial intelligence

Repository sessions map Time, Author, Branch, and Path into a view designed for desktop and immersive analysis.

OpenXR with a practical fallback

VR / AR capability detection preserves a deterministic desktop mode when an OpenXR runtime is unavailable.
