+**Phase B — Perspective Deep-Dive** (PARALLEL, only for multi-perspective, max 4):
 Each perspective agent receives shared Layer 1 results, performs only Layer 2-3 on its relevant subset.
 Skip if single-perspective (single mode proceeds directly to Step 2 CLI analysis with Layer 1 results).
 
+**CRITICAL — Parallel Execution**: Launch ALL perspective Agent() calls in the SAME response block so Claude Code executes them concurrently. Do NOT use a loop that waits for each agent before starting the next.
