An AI-native OS shell with a behaviourally-verified Rust authority core.
Kaira OS is an AI-native operating-system shell: a Rust Core that gates every action, paired with a large Python companion that drives an on-screen 3D character. The daemon speaks only over a local Unix socket.
The Core is a permission engine with seven authority levels — Observe, Suggest, Safe, UserApproved, SnapshotRequired, Critical, Sovereign (L0–L6) — verified by behaviour, not by claim: a reboot is actually refused, an app-launch actually waits for consent. A cross-process kill-switch (mechanism verified in code, measured well under its 2-second budget) can freeze both sides.
It is local-first: the Core daemon opens no TCP ports (AF_UNIX only); the single network listener is an optional mobile-pairing bridge restricted to a private Tailscale network. An external AI/MCP actor is held below hard action ceilings.
It is large and heavily tested — roughly 92k lines of Rust across 11 crates and 85k of Python, with about 1,300 Rust tests and 4,900 Python tests. The core is verified; driving the 55-bone 3D character live on the GPU is the current build front.
