macOS Design

Selection boundary. Automatic selection supplies design and material policy only. Prototype or artifact writes need task authorization; blessing requires the user's live sign-off. Freeze, capture, and production mutation remain separately authorized work owned by their corresponding stages.

Agent output fails on macOS when the interface is styled before it is structured, and no design file is authoritative for Liquid Glass — the operating system is: the only honest proof of an approved design is the design running, from fixtures, signed off live. It produces the preference system and the runnable prototype proving it, and carries the Liquid Glass material authority. Of the family's four stages — design, bless, freeze, audit — it owns design and bless (the material only exists at runtime); freeze belongs to tailrocks-macos-visual-baseline, current-render verification to tailrocks-macos-visual-qa, and implementation comparison to tailrocks-macos-visual-regression; independent taste review remains tailrocks-macos-design-review, and tailrocks-plan refuses a screen contract with no blessed reference.
