Execution Requirements

This subtree is the review-first source of truth for execution behavior, runtime boundaries, blocking semantics, diagnostics policy, and validation expectations.

Use these pages in this reading order:

• Modal State and Streaming
• Runtime Boundaries and Action Commands
• Motion and Timing
• Variables, Control Flow, and Calls
• Tools, Diagnostics, and Validation

The goal is to keep execution requirements reviewable by domain instead of in a single monolithic page.
