Module models 

Data models for workflows, instances, pointers, events, and execution results. Core data models for workflows, execution pointers, events, and results.

These types are the building blocks of the WFE runtime. Most are serialized to JSON when persisted or sent over the wire.

Modules

artifact

OCI-compatible artifact references and blobs. Artifact model for OCI-compatible workflow inputs.

condition

Step condition evaluation (used by if_do and while_do).

error_behavior

Error handling behavior for failed steps.

event

External events and subscriptions.

execution_error

Errors that occur during step execution.

execution_pointer

The runtime pointer tracking a step’s execution state.

execution_result

The result returned by a step, controlling flow and persistence.

lifecycle

Lifecycle event types (started, completed, failed, etc.).

poll_config

HTTP polling configuration for PollEndpointStep.

queue_type

Work queue classification (workflow vs event queue).

scheduled_command

Commands scheduled for future execution.

schema

JSON Schema support for workflow definitions.

service

Service definitions and readiness probes.

status

Workflow and pointer status enums.

workflow_definition

The static workflow definition (steps, outcomes, metadata).

workflow_instance

The mutable runtime instance of a workflow.
