CLI Show Fields

--show FIELD reads fields from the payload produced by the selected route. There is no separate CLI allow-list: any key that exists in the returned payload can be read, and nested dictionaries can be addressed with dot paths.

Plain --show prints a readable representation. Use --json --show FIELD for machine-readable JSON.

The lists below are ordered by practical usefulness for users: summary and physics-facing fields first, generated artifacts next, and route/debug/legacy fields last.

For the physical meaning of recurring terms such as OSSG, MSG, ACC primitive, operation views, spin texture, Wyckoff chains, and vector constraints, see Concepts.
