## ProcessRunSchema


A concrete execution of a [ProcessTemplateSchema](ProcessTemplateSchema.md#recap.ProcessTemplateSchema).


Usage

``` python
ProcessRunSchema()
```


A [ProcessRunSchema](ProcessRunSchema.md#recap.ProcessRunSchema) is the primary provenance record. It links together:

- The workflow that was executed (`template`).
- The resources that were used (`assigned_resources`).
- The parameter values captured at each step (`steps`).
- The namespace it belongs to (`namespace_id`).

Chain multiple process runs by using the output resource of one run as the input of the next, creating a queryable provenance graph.

Attributes: name: Display name for this run (e.g. `"Run 001"`). description: Free-text description of what this run represents. namespace_id: UUID of the owning Namespace. template: The [ProcessTemplateSchema](ProcessTemplateSchema.md#recap.ProcessTemplateSchema) this run instantiates. steps: Mapping of step name → `~recap.schemas.step.StepSchema` with live parameter values. assigned_resources: Mapping of slot name → `~recap.schemas.resource.ResourceAssignmentSchema` binding resources to their slots. Keyed by `~recap.schemas.resource.ResourceSlotSchema.name` so that a specific assignment can be retrieved directly, e.g. `run.assigned_resources["crystal_plate"]`.
