# 변경 취소 안내 · Origin UI

The acquired original files are unchanged. Source revision: 60b6b444e6dfb670fab47bfb0da9dd9da1f8150b. Each exact file hash and any demo content revision is recorded in provenance.json. Keep all included license notices.

- The unchanged official Origin example apps/origin/registry/default/components/comp-287.tsx is the entry, pinned to cosscom/coss revision 60b6b444e6dfb670fab47bfb0da9dd9da1f8150b under the apps/origin MIT notice.
- The historical 21st Alert(layout/icon/action/isNotification) wrapper is not reused. The matching official variant uses explicit DOM; historical wrapper byte identity is not claimed.
- The original Origin theme is supplied by the host. The source implementation and its available Button/cn dependencies remain unchanged.
- The original You‘ve made changes! copy, small Undo button, and Close banner control are retained. No rollback state, undo window, or dismiss handler is added.
- Host spacing and fallback tokens come from runtime/author-styles.css. runtime/applied-theme.css contains the selected original author theme and overrides fallback tokens.

Open the standalone HTML to run with all JavaScript and CSS bundled locally. ?theme=light and ?theme=dark select the host theme. The parent gallery must use an opaque allow-scripts sandbox. No external requests are required.

For source reuse, start with Usage.tsx and the unchanged baseline demonstration. Resolve @/ imports to their included matching author files and install the exact package versions in provenance.json. The host mount and styles are supplied for reference.

Build success and the ready message do not prove runtime or accessibility behavior. Browser validation is recorded separately.
