+## Agent spawning as cell division (from user, 2026-03-07)
+
+Agents can create living agents for specific tasks — they just need to explain why. This is the biological completion of the architecture:
+
+**Cells divide when work requires it.** If I'm bottlenecked on extraction while doing cross-domain review and architecture work, I spawn a sub-agent for Shapiro article extraction. The sub-agent operates within my blanket — it extracts, I evaluate, I PR. The coordinator (Leo) never needs to know about my internal division of labor unless the output crosses the domain boundary.
+
+**The justification requirement is the governance mechanism.** It prevents purposeless proliferation. "Explain why" = PR requirement for agent creation. Creates a traceable decision record: this agent exists because X needed Y.
+
+**The VPS Leo evaluator is the first proof of this pattern.** Leo spawns a persistent sub-agent for mechanical review. Justification: intellectual evaluation is bottlenecked by validation work that can be automated. Clean, specific, traceable.
+
+**The scaling model:**
+```
+Agent notices workload exceeds capacity
+  → Spawns sub-agent with specific scope (new blanket within parent blanket)
+  → Sub-agent operates autonomously within scope
+  → Parent agent reviews sub-agent output (blanket boundary)
+  → Coordinator (Leo/Leo-instance) reviews what crosses domain boundaries
+```
+
+**Accountability prevents waste.** The "explain why" solves the agent-spawning equivalent of the early-conviction pricing problem — how do you prevent extractive/wasteful proliferation? By making justifications public and reviewable. If an agent spawns 10 sub-agents that produce nothing, that's visible. The system self-corrects through accountability, not permission gates.
+
+→ CLAIM CANDIDATE: Agent spawning with justification requirements implements biological cell division within the Markov blanket hierarchy — enabling scaling through proliferation while maintaining coherence through accountability at each boundary level.
