# Example coverage

> How the SDK examples prove primitive composition across surfaces, capabilities, safety, and distribution.

The SDK examples are not separate demos. They are coverage fixtures for the
primitive catalog. Each example starts from `budscollab.blueprint.json`, compiles
to `budscollab.package.json`, and stays review-gated until validation, review
storage, signing, and install policy exist.

Coverage is declared in `primitive-coverage.json` and checked by
`pnpm validate:sdk-distribution`.

| Example         | Surfaces                                      | Capabilities                             | Distribution    |
| --------------- | --------------------------------------------- | ---------------------------------------- | --------------- |
| Status Chip     | widget, chat panel                            | JSON-render UI, room state               | personal-widget |
| Room Counter    | widget, fullscreen, dock, chat panel          | JSON-render UI, host data, room state    | full-app        |
| Piano           | widget, fullscreen, dock, chat panel          | JSON-render UI, room state, safe actions | full-app        |
| Overlay Compass | widget, fullscreen, dock, overlay, chat panel | JSON-render UI, room state, safe actions | published-wall  |

Together, these examples cover widget, fullscreen, dock, overlay, and chat-panel
surfaces. They also show the intended safety default: host-rendered JSON UI,
read-only tools, explicit distribution target, and review evidence before any
install claim.
