# portableKernelDecision

A portable kernel decision record carrying admitted, code, message.

Last updated: 2026-09-09

Package: compute.kernels | Status: source-declared

Tags: compute, compute.kernels, cpu, kernels, method, source-example, thing, yeho

Describe reusable compute kernels and their workload contracts.

```yh
external thing portableKernelDecision
```

- bool admitted: Stores admitted as bool.
- text code: Stores code as text.
- text message: Stores message as text.
- portableKernelDecision(bool admitted, text code, text message): Portable kernel decision.
- Describe() returns text: Describe.

## Use portableKernelDecision

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

Verification: type checked

```yh
using compute.kernels

// Describe reusable compute kernels and their workload contracts.
portableKernelDecision sample = portableKernelDecision(true, "code", "message")
Console.Log(Text.From(sample.admitted))

```

Save this beside start.yh as project.mech:

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

[app]
kind = "headless"

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

[[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.kernels--portableKernelDecision/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## portableKernelDecision.Describe

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

Verification: type checked

```yh
using compute.kernels

// Describe.
portableKernelDecision instance = portableKernelDecision(true, "code", "message")
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.
