Mara: That shift in framing is the whole architecture. The proposal is to replace the Agent as the unit of agency with something called a MUSE Act — Mutually Untrusting, Specific, and Ephemeral. Each Act independently asks whether its input is appropriate before proceeding.

The usual abstraction for an AI system with initiative is the Agent. An Agent is given a name, a role, a model, memory, tools, credentials, permissions, perhaps a budget, and enough persistence to pursue a goal over time. This is convenient as a programming abstraction. It is a poor protection abstraction.
