Most AI systems treat cognitive science as inspiration, not specification. PHI // DRIFT treats it as engineering requirements. The architecture implements three theoretical frameworks as first-class modules: Global Workspace Theory a capacity-5 spotlight with broadcasting dynamics. Information only reaches the global workspace when it wins competition across the seven cognitive layers. The layers are not decorative each has a specific function, memory filter, and state variable. IIT Φ proxy a seven-dimension integrated processing approximation used as one component of the PEDI continuity metric. We don’t claim consciousness. We claim measurably different behavioral structure. Jungian shadow unintegrated behavioral patterns tracked as a weighted state variable with exponential TTL decay: w(t) = w₀ × exp(-t/τ). Three operating modes SECURITY (τ=15), BALANCED (τ=30), CONSERVATIVE (τ=50). Shadow influences confidence scoring but cannot veto decisions unless Ethos allows it.…
