Modern agent systems are increasingly capable, able to plan, remember, and write code. Yet they suffer from a fundamental limitation: they remain anonymous to their users. They do not intrinsically know who they serve, what their user values, or when a human life enters a crisis.

This paper introduces the Constitutional Identity Layer (CIL), a formal governance framework that binds an autonomous agent system to its human and business hosts. The CIL is defined as an 8-tuple comprising Person, Business, Relationship, Life Domain, Operating Context, Permission Set, Transition State, and Emergency Policy, governed by well-defined operators for projection, scoping, delegation, escalation, and evolution. Unlike static user profiles, the CIL supports dynamic authority that shifts when roles change, life-domain separation, and explicit constitutional constraints that no agent may override.

We situate this framework within the broader discourse on constitutional AI, agent alignment, and context-aware multi-agent systems, integrating it with an existing agent ecosystem. A formative pilot evaluation (N=15) comparing a baseline system to the CIL-augmented system demonstrates promising directional signals, including improvements in task completion (76% to 88%), trust (2.8 to 4.1 out of 5), and 30-day retention (42% to 78%).

The CIL provides a necessary theoretical and practical foundation for host-aware agent operating systems, representing a step toward AI that is accountable, adaptive, and constitutionally aligned with human hosts.
