Package: compute.graph | Status: source-declared

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

Describe compute work as an explicit graph with package-owned validation and scheduling metadata.

```yh
external thing graphExecutionStep
```

- text nodeName: Stores node name as text.
- text operatorKind: Stores operator kind as text.
- text requestedPath: Stores requested path as text.
- text resolvedPath: Stores resolved path as text.
- bool cacheHit: Stores cache hit as bool.
- bool fallbackUsed: Stores fallback used as bool.
- bool fused: Stores fused as bool.
- tensorBuffer output: Stores output as tensorBuffer.
- text note: Stores note as text.
- Describe() returns text: Describe.

## Use graphExecutionStep

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

Verification: type checked

```yh
using compute.graph

// Describe compute work as an explicit graph with package-owned validation and scheduling metadata.
graphExecutionStep sample = graphExecutionStep()
Console.Log(Text.From(sample.nodeName))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.compute_graph__graphexecutionstep"
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.graph"

```

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.graph--graphExecutionStep/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## graphExecutionStep.Describe

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

Verification: type checked

```yh
using compute.graph

// Describe.
graphExecutionStep instance = graphExecutionStep()
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.
