Build YUI's reusable control, layout, interaction, text, accessibility, and retained-rendering models.

```yh
external thing yuiPartialRebuildReport
```

- int generation: Stores generation as int.
- int measuredElements: Stores measured elements as int.
- int layoutElements: Stores layout elements as int.
- int paintElements: Stores paint elements as int.
- int invalidatedArea: Stores invalidated area as int.
- int surfaceArea: Stores surface area as int.
- bool noWork: Stores no work as bool.
- text reason: Stores reason as text.
- text diagnostic: Stores diagnostic as text.
- yuiPartialRebuildReport(int generation, int measuredElements, int layoutElements, int paintElements, int invalidatedArea, int surfaceArea, text reason, text diagnostic): Yui partial rebuild report.
- RenderReport() returns text: Render report.

## Use yuiPartialRebuildReport

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

Verification: type checked

```yh
using ui

// Build YUI's reusable control, layout, interaction, text, accessibility, and retained-rendering models.
yuiPartialRebuildReport sample = yuiPartialRebuildReport(1, 1, 1, 1, 1, 1, "reason", "diagnostic")
Console.Log(Text.From(sample.generation))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.ui__yuipartialrebuildreport"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "graphics.image"
version = "0.1.0"
path = "../../../yeho/packages/graphics/image"

[[dependencies]]
package = "graphics.text"
version = "0.1.0"
path = "../../../yeho/packages/graphics/text"

[[dependencies]]
package = "host.ui_services"
version = "0.1.0"
path = "../../../yeho/packages/host/ui_services"

[[dependencies]]
package = "ui"
version = "0.2.0"
path = "../../../yeho/packages/ui"

```

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/ui--yuiPartialRebuildReport/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## yuiPartialRebuildReport.RenderReport

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

yuiPartialRebuildReport instance = yuiPartialRebuildReport(1, 1, 1, 1, 1, 1, "reason", "diagnostic")
text result = instance.RenderReport()
Console.Log(Text.From(result))

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