## Gate Decision

**Dual sign-off required**: Studio Producer (strategic) + Reality Checker (technical)

- **APPROVED**: Proceed to Phase 2 with full Architecture Package
- **REVISE**: Specific items need rework (return to relevant Step)
- **RESTRUCTURE**: Fundamental architecture issues (restart Phase 1)
