## CHECKPOINT: Requirements Section Complete

The Requirements section has been generated.

**Why checkpoint here?** Requirements shapes:
- NFRs (how requirements are met)
- Out-of-Scope (what's NOT required)
- Risks (technical feasibility)
- Roadmap (priority and sequencing)

**Options**:
A) Approve — Continue to remaining sections
B) Modify — Edit requirements, then continue
C) Restart — Regenerate from Problem phase
D) Cancel — Stop execution
