| Parameter    | Meaning                                                                        |

## Value operations

Kotlin provides `copy`, destructuring components, `equals`, `hashCode` and `toString`. Lists/maps
are not defensively deep-copied; keep supplied collections stable. Model construction does not run a
parser or apply application policy.

## Example

The following Kotlin statements run inside a function with `import link.roadio.cuegrain.*`. Fully
qualified names identify optional/repair-package APIs.

```kotlin
val genre = RiffGenre("Rock", confidence = 0.8f)
check(genre.value == "Rock")
```
