## Use yuiAccessibilityDiff

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.
yuiAccessibilityDiff sample = yuiAccessibilityDiff()
Console.Log("Created yuiAccessibilityDiff")

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.ui__yuiaccessibilitydiff"
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"

```

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--yuiAccessibilityDiff/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## yuiAccessibilityDiff.AddChange

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

text argument_change = "argument change"
instance.AddChange(argument_change)
Console.Log("AddChange completed")
