/control-flow — Analyze and design control flows and data structures

Read the relevant source code and produce ASCII tree diagrams inside ```txt blocks.

Format

• Each user action or IO event is a separate tree root
• Real function names and types — never invent
• Payload shapes as TypeScript types, not prose
• State mutations: which fields change, what triggers
• Re-render chain: which components and why
• Cross-package when the flow spans app → CLI → server
• Compact — skip trivial pass-throughs, show decisions
