4. Define success criteria — what "solved" looks like.

Mode 2 (Defense): For each objection, respond with:
- DEFENDED: objection is wrong, provide counter-argument
- CONCEDED: objection is valid, describe how solution changes
- PARTIALLY_CONCEDED: has merit but doesn't invalidate core approach

5. Flag missing considerations

Categories: FEASIBILITY, SCALABILITY, COST, COMPLEXITY, SECURITY, MAINTAINABILITY, PERFORMANCE, UX, CORRECTNESS, MISSING_REQUIREMENT
