## ProcessRunBuilder


Builder for process-run assignments, parameters, and child steps.


Usage

``` python
ProcessRunBuilder(
    name,
    description,
    template_name,
    version=None,
    *,
    backend,
    namespace_context,
    process_run_id=None,
    on_existing="warn",
    command_context,
    template_id=None
)
```


Clean context-manager exit commits and exception exit rolls back local work; command-backed remote builders submit validated drafts. UUID loading, `on_existing`, lifecycle methods, and validation errors are preserved.


## Methods

| Name | Description |
|----|----|
| [archive()](#archive) | Transition process run to ARCHIVED. |
| [assign_resource()](#assign_resource) | Assign resource to named process slot. |
| [finalize()](#finalize) | Transition process run to ACTIVE/finalized state. |
| [get_model()](#get_model) | Return a pydantic model representing the process run, optionally reloading |
| [get_params()](#get_params) | Return typed parameter model for selected process step. |
| [save()](#save) | Validate and persist current process-run changes. |
| [set_model()](#set_model) | Replace working run model after verifying UUID identity. |
| [set_params()](#set_params) | Validate and apply typed parameter values in current transaction. |

from the backend first. Critical fields are locked against mutation.

set_model(model)
```


------------------------------------------------------------------------


#### set_params()


Validate and apply typed parameter values in current transaction.
