asHook

A reusable logic unit for Proto UI prototypes

asHook is a reusable logic unit in Proto UI.
It is not an interaction subject by itself. Instead, it is attached to a prototype to reuse behavior such as button semantics, toggle semantics, or open-state logic.

As compound prototypes evolve, an asHook may also be built on top of existing protocol capabilities. For example:

  • anatomy.order provides an ordered host view for parts in the same family
  • asCollection() and asCollectionItem() build a minimal collection interaction layer on top of that ordered view

This is important for Proto UI’s layering:

  • anatomy.order remains an enhancement of structural capability
  • asCollection remains reusable behavior built on top of that capability

In other words, Proto UI does not need to introduce a new top-level collection runtime concept first. A higher-level semantic layer can still grow through asHook composition.
