This entry unifies three complementary frameworks — Superposition framework v1.0, Entanglement framework v1.0, and Double-slit framework v1.0 — into a coherent trilogy. Together they show that quantum paradoxes can be explained as operational consequences of the Information Field Economy Principle. Summary:Superposition: collapse occurs into the state that requires the least information cost.Entanglement: correlations are global reorganizations of the field according to the same economic rule.Double-slit: interference is realized when the wave pattern is the cheapest description; particle-like outcomes appear only when which-path information increases the cost. All three rest on the same anchoring: Planck time (tₚ), the photon clock, and the Information Field Economy Principle. By combining them, the trilogy transforms three classical paradoxes into a single operational structure that explains why nature always chooses the least costly informational pattern.
