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

terminal

AUP Web-only widget `terminal`: 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

xterm.js WebSocket terminal widget with its own endpoint protocol — independent of the AUP session protocol.

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 type: "terminal" with props.endpoint (and optional rows/font). Requires live connection.

Surfaces

Interactive Web only. Snapshot mode shows a placeholder.

Fallback

Missing endpoint → placeholder. No shared degradation chain. Trust/endpoint review required.

Sample

Not docs-safe. Side effects, write paths, native-only surfaces, or trust-sensitive endpoints make a public sample inappropriate. Keep this page as a boundary and evidence index.
