ARC 2.0.0-beta.28 · AUP Web-only widget

app-footer

AUP Web-only widget `app-footer`: purpose, boundaries, surfaces, fallback, and evidence.

AUP Web-only widget — not a cross-device primitive; not a Web Device layout component.

The name is registered in AUP_WIDGETS (packages/aup/src/aup-types.ts). It can be accepted by structure verification and implemented by a Web runtime (or native target where noted). It is not one of the 18 cross-device AUP_PRIMITIVES, does not enter DeviceCaps.primitives via fillPrimitives, and is not a Web Device theme/site layout component (for example content-card or page-breadcrumb).

Purpose

Brand shell footer for interactive AUP apps: optional brand block, link columns, and social slots. Also has a static document primitive renderer for site-like shells.

Boundaries

  • Do not document this type as a portable primitive.
  • Do not mix it with Web Device layout-component reference pages under widgets/.
  • A parser-accepted name is not a portability or product-readiness claim.

Author entry

AUP app shell node type: "app-footer". Showcase page prim-app-footer.

Surfaces

Interactive Web + document RENDERERS (app-footer). Not Markdown content contract.

Fallback

No shared degradation chain. Empty props produce minimal chrome.
