Why: the Dev combination check requires every nested agent-intent pin to equal 343b1e6 (I2 increments 1-2 on intent main); the nested native pin follows to 3a1ad5a (which itself carries intent 343b1e6). Evidence: tree-only pin moves; squad code does not consume the new ports. Impact: none. Refs: Agent-Native#23, I2 increment 3 cascade
