Inspect device capability catalogs and model resource lifetimes and placement decisions.

```yh
external thing computeFenceContract
```

- int id: Stores id as int.
- text queueId: Stores queue id as text.
- text status: Stores status as text.
- int submittedTick: Stores submitted tick as int.
- int completedTick: Stores completed tick as int.
- bool cancellationRequested: Stores cancellation requested as bool.
- text errorCode: Stores error code as text.
- text errorMessage: Stores error message as text.
- computeFenceContract(int id, text queueId, int submittedTick): Compute fence contract.
- IsTerminal() returns bool: Is terminal.
- Succeeded() returns bool: Succeeded.
- Describe() returns text: Describe.

## Use computeFenceContract

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

Verification: type checked

```yh
using compute.device

// Inspect device capability catalogs and model resource lifetimes and placement decisions.
computeFenceContract sample = computeFenceContract(1, "queue Id", 1)
Console.Log(Text.From(sample.id))

```

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

computeFenceContract instance = computeFenceContract(1, "queue Id", 1)
bool result = instance.IsTerminal()
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.
