Module execution 

Execution boundaries for workflow runs.

ExecutionScope owns the execution directory lifecycle:

• creation mode (open_or_create, create_generated, create_named),
• path derivation for per-task recordings,
• and opening of previously used scopes.

Boundary

This module is intentionally filesystem-only. It does not define task policies, scheduling, artifact identity rules, or payload serialization. The downstream caller owns those concerns and consumes the directories this module provides.

Structs

ExecutionScope

One created or reopened study-execution directory.
