"Agentic design systems" promise autonomous AI loops that self-heal and generate components — but the real danger isn't the agents, it's removing human ownership from the judgment layer. Design systems are fundamentally governance technologies encoding collective decisions that organizations remain accountable for, meaning no agent loop can replace the human who owns what "pass" means. Agents belong between the gates, handling generation and conformance checking, while humans must own every gate — otherwise the result is just confident, unowned drift dressed in system authority.
