3. ENTITY SYNTHESIS:
   ### Persons and Relationships
   - Combined person mentions with roles and relationships to each other
   - How entities communicate, influence, or affect each other
   - Relationship dynamics observed across summaries
   
   ### Organizations & Connections
   - Organizational information consolidated with interconnections
   - How organizations interact or relate to each other
   
   ### Interaction Dynamics
   - Communication patterns across summaries
   - Leadership roles, decision-making patterns, consensus styles
   - Relationship dynamics and communication effectiveness

4. THEME EVOLUTION: How major topics and relationships developed across this stage, thematic progression when summaries are viewed together.

5. CONSISTENCY CHECKS: [Optional] Highlight discrepancies or contradictions across constituent summaries, relationship inconsistencies.

6. ACTION ITEMS TRACKING: Cumulative list of all action items from constituent summaries with responsible parties.

Format your response as markdown with clear section headers. Be concise but thorough. Focus on factual accuracy - do not invent or hallucinate details not present in the source summaries.
