Module introspect 

Typed, whitelisted component-introspection registry for the dynamic DOM n.components() / n.component("LayoutBox") reads (design 4.7).

Each exposable Lumen component registers a reader that turns its public fields into a (name, value) string map. The read is bounded and typed; there is no raw transmute or arbitrary memory access, and a name that is not in the registry is an error rather than an empty read. The runtime runs the registry against every element each tick and publishes the resulting maps into the cross-thread snapshot the script hosts read.
