📋 Decision Context

Question:

How to add a Danger Zone feature to Universe Hub for emptying universes during development?

Task: Session 50.9: Add Danger Zone to Universe Hub for emptying universe

🎯 Decision Made

Chosen:

Added Danger Zone section at bottom of Universe Hub with: 1) Red-themed UI with dashed borders and warning message, 2) Empty Universe button showing module count, 3) Double-confirmation dialogs before executing, 4) Iterative module deletion with progress logging, 5) Cross-tool sync event 'universe:emptied' for notifying other tools, 6) Toast notifications for success/partial success/failure

Options Considered:

Add empty button with confirmation
Add batch delete API endpoint
Use settings modal for dangerous actions

💭 Reasoning

During AI development and testing, being able to quickly reset a universe to test the full generation flow from scratch is essential. The double confirmation prevents accidental data loss while making the feature accessible for legitimate use cases.
