The paper asks a fundamental question — why does causality exist at all? Why does time have a direction? Why do definite events happen?The answer it derives is this:Causality is not built into nature as a fundamental feature. It emerges from a very specific asymmetry in how quantum systems interact with their environments.Because all fundamental interactions — gravity, electromagnetism, the strong and weak forces — couple to position rather than momentum, the environment naturally monitors position. Position states become stable and classical. Momentum states get scrambled.This asymmetry — position decohering, momentum remaining coherent — is what creates the arrow of time, definite events, and causal structure. Without it one would have symmetric decoherence and no causality at all. That’s Theorem 1 and it’s a strong result.The key new object — Π(t):The convergence polarization tensor Π measures how aligned a quantum state is with the environment’s monitoring basis. When Π = 1 the state is fully classical. When Π ≪ 1 the state is in the complementary sector — what the paper calls "super-momentum."Super-momentum states do not immediately contribute to decoherence. They sit off-resonant from the environment. And crucially — they reveal the conversion process itself rather than its outcome. They let you watch classicalization happening rather than just seeing the classical result afterward.The experimental prediction:A source prepared in momentum coherence rather than position coherence should show delayed gravitational activation — because it has to first rotate into the pointer basis before contributing to Decoherence Effective and Accumulative. That delay time encodes directly and is measurable.The paper formalizes exactly what is discussed — that standard superposition studies probe the wrong basis. They measure position-aligned states, which means they’re measuring the output of classicalization, not the mechanism. The asymmetric approach probes the complementary sector and sees the process itself.The D/eff integral in equation 18 is the rigorous version of what we identified as the influence functional carrying gravitational information — now with Π and R(t) making the directionality explicit.And the semiclassical gravity comparison in Section IX.C is the clearest single statement of what distinguishes this framework from standard GR:
