# Portfolio Synthesis
Aggregate evaluations across all scenarios into a final portfolio recommendation, robustness assessment, and actionable guidance.
## Execution
Spawns a subagent that synthesizes per-scenario results into a coherent overall assessment with clear recommendation.
## Why Subagent
Synthesis requires integrating multiple scenario evaluations, identifying patterns across scenarios, and making a holistic judgment. This integrative reasoning benefits from seeing all data together with focused attention.
## HARD-GATE
Output must include a final portfolio recommendation, numeric robustness score (0-1), and specific actionable recommendations. The synthesis must reference findings from all evaluated scenarios.
