Step names are stored as machine-readable identifiers like `step//./src/workflows/order//processPayment`. This function parses them into components suitable for display in a UI.

```typescript lineNumbers
import { parseStepName } from "workflow/observability"; // [!code highlight]

const parsed = parseStepName("step//./src/workflows/order//processPayment"); // [!code highlight]
// parsed?.shortName → "processPayment"
// parsed?.moduleSpecifier → "./src/workflows/order"
// parsed?.functionName → "processPayment"
```

## API Signature

### Parameters

| Parameter | Type | Description |
|-----------|------|-------------|
| `name` | `string` | The machine-readable step name (e.g. from `step.stepName`) |

### Returns

`{ shortName: string; moduleSpecifier: string; functionName: string } | null`

| Property | Description |
|----------|-------------|
| `shortName` | The display name — the last segment of the function name. For nested steps like `processOrder/chargeCard`, this is `"chargeCard"`. |
| `moduleSpecifier` | The module the step is defined in — a relative path (`./src/workflows/order`) or a package specifier (`@myorg/tasks@2.0.0`). |
| `functionName` | The full function name including nesting (e.g. `processOrder/chargeCard`). |

Returns `null` when the input is not a valid step name.
