SPT Model
Same node, two regimes. Free-flipping → wave behavior (interference). Càn-anchored → particle behavior (clicks). One geometric mechanism, no metaphysics.
Toy Action S
One Action governs all three lenses. V(φ) = -λ cos(Δφ) is the phase-coupling potential.
State of the node
A = Càn-anchor strength. A=0 → pure wave. A=1 → pure click.
Englert duality
Visibility (interference contrast) and distinguishability (which-path info) are complementary.
Fringe spacing
λ = wavelength, L = screen distance, d = slit separation.
