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

```yh
external thing computeSubmissionContract
```

- int id: Stores id as int.
- int fenceId: Stores fence id as int.
- text kind: Stores kind as text.
- text sourceId: Stores source id as text.
- text destinationId: Stores destination id as text.
- int byteCount: Stores byte count as int.
- int dependencyFenceId: Stores dependency fence id as int.
- int readyTick: Stores ready tick as int.
- int timeoutTick: Stores timeout tick as int.
- bool forceFailure: Stores force failure as bool.
- text failureCode: Stores failure code as text.
- computeSubmissionContract(int id, int fenceId, text kind, text sourceId, text destinationId, int byteCount, int dependencyFenceId, int readyTick, int timeoutTick, bool forceFailure, text failureCode): Compute submission contract.
- Describe() returns text: Describe.

## Use computeSubmissionContract

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.
computeSubmissionContract sample = computeSubmissionContract(1, 1, "kind", "source Id", "destination Id", 1, 1, 1, 1, true, "failure Code")
Console.Log(Text.From(sample.id))

```

Save this beside start.yh as project.mech:

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

[app]
kind = "headless"

[[dependencies]]
package = "compute.buffer"
version = "0.1.0"
path = "../../../yeho/packages/compute/buffer"

[[dependencies]]
package = "compute.device"
version = "0.1.0"
path = "../../../yeho/packages/compute/device"

[[dependencies]]
package = "compute.tensor"
version = "0.1.0"
path = "../../../yeho/packages/compute/tensor"

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

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

```

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/compute.device--computeSubmissionContract/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## computeSubmissionContract.Describe

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

Verification: type checked

```yh
using compute.device

// Describe.
computeSubmissionContract instance = computeSubmissionContract(1, 1, "kind", "source Id", "destination Id", 1, 1, 1, 1, true, "failure Code")
text result = instance.Describe()
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.
