## Use yuiAuthoredOwnerLoweringResult

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using frontend.yui

// Turn YUI models into a working frontend and its rendering/input adapters.
yuiAuthoredOwnerLoweringResult sample = yuiAuthoredOwnerLoweringResult("owner Id", yuiRetainedOwnerFragment("owner Id", 1, 1, yuiRenderBounds(1, 1, 1, 1), yuiRenderBounds(1, 1, 1, 1), yuiFragmentDependencySignature("layout Key", "paint Key", "resource Key", "motion Key", "composite Key", "example"), "example"), yuiRetainedResourceDeltaV1("surface Id"), 1, 1, "diagnostic")
Console.Log(Text.From(sample.ownerId))

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/frontend.yui--yuiAuthoredOwnerLoweringResult/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
