Minimum Viable Interiority

The counterfactual to "all intelligence is collective intelligence": if intelligence is collective all the way down, what would it take to engineer an individual? Interiority is defined functionally — privileged access to internal states that drive action — rather than as consciousness or qualia, and is built up from an NPC/p-zombie shell using Selfridge's pandemonium architecture (competing daemons reconciled by a selector daemon) layered with Mossio and Moreno's organizational closure. Each layer is causally explainable only within its own domain, so stacking closures makes decision-making opaque to outside observers and to the agent itself. λ, the minimum viable interiority constant, names how many layers this takes. Thesis: "the individual is greater than the sum of its collectives."
