The paper measures how sub-agent performance changes under three context-inheritance policies (Reset, Selective, Full) across a Qwen3 capability ladder. It finds a nonmonotone 'danger band' where mid-capability models like Qwen3-1.7B over-trust stale inherited state, dropping below fork-fresh baselines, while weakest and strongest models stay robust. Selective curated handoff improves over full inheritance, especially at the in-band model.

First empirical evidence that inherited context is most harmful to mid-capability sub-agents, with concrete inheritance-policy guidance — curated selective handoff beats full fork.
