Module ids 

Execution & Telemetry IDs - Graph-centric observability identifiers

This module defines the canonical ID types for the enact-core runtime, aligned with the Execution/Step/Artifact hierarchy.

ID Format

All IDs use prefixed KSUID (K-Sortable Unique IDentifier):

• exec_[27 alphanumeric chars] - ExecutionId
• step_[27 alphanumeric chars] - StepId
• artifact_[27 alphanumeric chars] - ArtifactId

Hierarchy

ExecutionId (The Run)
  ├── StepId (Type: ToolNode) -> Artifacts
  ├── StepId (Type: LlmNode)  -> Artifacts
  └── StepId (Type: GraphNode "Sub-Agent")
        └── ExecutionId (Nested run)
              └── StepId...
