Autonomy modes (coming next)

Identity

Use when

• Only under Coming next, on its demo page. Why: Agents acting on their own under these modes is not built yet; the demo shows the plan with sample data.

Do not use when

• In the demos grid or as proof. Why: It is a plan, so it never sits with the demos that show running code.

Anatomy

Made of: showcase-frame, control, callout, caption.

Used in: pages directly.

Runtime and reuse

1. stylesheet: /css/site.css. Built Site tokens, core and registered element CSS; preserve modes, focus and responsive rules.

2. stylesheet: /css/demos.css. Existing legacy demo styles where the rendered specimen uses them.

3. font: /fonts/. Self-hosted files referenced by Site @font-face, with licences; Japanese locale overrides remain applicable.

4. data: /i18n/ja.json. Required for a Japanese root; English interface fallbacks are authored in source. Root language changes require disposal and fresh preparation.

5. Static fallback: Original build-time specimen remains readable before loading and after chunk/initialization failure; enhancement controls retain authored hidden state.

6. Before DOM initialization the configured host awaits apps/showcase/site/demos/autonomy.ts#prepare for this root with a mount-owned AbortSignal. Preparation must throw on missing/invalid data; disposal/replacement aborts pending work, and a stale result cannot initialize or claim ready.

7. Configured initializer: apps/showcase/site/demos/autonomy.ts#init. The host owns transactional static-markup restoration and runtime state.

8. Consumer module (imports relative to the configured source root):
   import { createRuntimeHost } from "./src/workflows/runtime-host";
   import { SITE_RUNTIMES } from "./apps/showcase/site/runtime-registry";
   const definition = SITE_RUNTIMES.find(entry => entry.binding.id === "autonomy");
   if (!definition || definition.binding.lifecycle.kind !== "managed") throw new Error("Managed runtime binding unavailable");
   const host = createRuntimeHost([definition]);
   export function mountRuntime(container: ParentNode) { return host.mountAll(container); }

9. After inserting the rendered markup, call mountRuntime(container) for the container holding [data-demo="autonomy"]. Retain the returned disposal function and call it before removing, replacing or remounting, including every Storybook args render. The configured host restores captured static markup/attributes on disposal or caught load/initialization failure; retry starts a fresh managed remount.

Accessibility passport

Content

Good: “Coming next · sample data”

Bad: “Live autonomy”

Japanese: Static explanatory/fallback copy remains English and is explicitly labelled. Prepared controls use root-owned EN/JA catalogue messages; native Japanese acceptance remains open.

Icons and illustrations

None: this element uses no icon or illustration of its own.

Decisions and exceptions

• D-SITE-008: One ShowcaseFrame for every self-playing element

Usage

9 uses across the built pages (measured by npm run site:system).

not-yet: The Loom Site Figma library is the last stage of the plan; this element is not mapped yet.
