Highlights

Read-only source ISO

Never modified in place. Changes are staged and reviewed first.

Changes → Test → Undo

Explicit staged workflow before production builds.

Windows + Linux

PySide6 GUI; WSL2 on Windows; native engine in the Debian package.

Verification-first

SHA-256, boot structure, manifests. Static evidence ≠ runtime proof.

AI App Studio

Optional experimental feature with review gates — not in the verified a72 path.
