The Agentic Shift: A Structural Redesign of Human–Machine Experience

This paper introduces the Supervisory Coherence Model (SCM), a framework linking autonomy anxiety, the undo contract, negotiated interaction grammar, interruption budgeting, and episodic interface architecture as a causal system governing human–agent collaboration. The SCM addresses the structural break in user experience created by agentic AI systems and proposes design primitives—reversibility, provenance, progressive disclosure, risk-tiered approvals, and escalation routing—that maintain supervision under autonomy.
