Overview

The dynamic-origin wrapper: marks values whose type came from an unchecked source. Carries a static facet that records the analyzer’s best static knowledge. See docs/type-specification/value-lattice.md for the algebra and docs/type-specification/special-types.md for the untyped/Dynamic relationship.

Construct via Rigor::Type::Combinator.dynamic(static_facet).
