SDUI data-shape bindings derived from logical view contracts. This package emits data only; SDUI
rendering, theming, and composition remain outside the portable Platform kernel and are supported
by separately versioned experience-tier packages.
Discovery boundary
This generator retains internal action/view contracts for trusted assembly and worker integration.
Its output is not an external audience catalog. Before disclosing definitions externally, omit
surface: "internal" entries from the source manifest and apply live audience disclosure rules.
