Reflection
sparkles:reflection is the dependency-free structural reflection kernel of the monorepo: one closed type classification and the member/field/property primitives — the field spine, getter discovery, and the value-like wrapper rule — that consumers build their own walks from.
Consumers supply semantics; the kernel supplies structure. The property tree, the text writers, query-path resolution, and serialization front ends dispatch on the same classification and the same field spine, so "what shape is this type" has exactly one answer across the repository.
