Represent tensor shapes, layouts, and numerical storage contracts.

```yh
external thing tensorPlanHint
```

- text label: Stores label as text.
- tensorShape shape: Stores shape as tensorShape.
- tensorPlacement placement: Stores placement as tensorPlacement.
- text executionPath: Stores execution path as text.
- text fallbackPath: Stores fallback path as text.
- text cacheKey: Stores cache key as text.
- bool cacheable: Stores cacheable as bool.
- bool reusable: Stores reusable as bool.
- text note: Stores note as text.
- tensorPlanHint(text label, tensorShape shape, tensorPlacement placement, text executionPath, text fallbackPath, text cacheKey, bool cacheable, bool reusable, text note): Tensor plan hint.
- HasFallback() returns bool: Has fallback.
- CanReuse() returns bool: Can reuse.
- Describe() returns text: Describe.

## Use tensorPlanHint

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

Verification: type checked

```yh
using compute.tensor

// Represent tensor shapes, layouts, and numerical storage contracts.
tensorPlanHint sample = tensorPlanHint("Player health", tensorShape("element Type", []), tensorPlacement("device", "memory"), "execution Path", "fallback Path", "cache Key", true, true, "note")
Console.Log(Text.From(sample.label))

```

Save this beside start.yh as project.mech:

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

[app]
kind = "headless"

[[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.tensor--tensorPlanHint/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## tensorPlanHint.HasFallback

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

Verification: type checked

```yh
using compute.tensor

// Has fallback.
tensorPlanHint instance = tensorPlanHint("Player health", tensorShape("element Type", []), tensorPlacement("device", "memory"), "execution Path", "fallback Path", "cache Key", true, true, "note")
bool result = instance.HasFallback()
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.
