The paper proposes that causality is not a primitive feature of reality but an emergent, branch-internal phenomenology produced by asymmetric decoherence. Because environmental interactions are generically position-local, they preferentially build records in a position-like pointer basis. The buildup of irreversible, redundant records generates definite events and temporal order for embedded observers. Coherence prepared in the complementary momentum sector remains temporarily off-resonant with this rendering process, making it the cleanest probe of onset dynamics. In a decoherence-conditioned gravity framework, this predicts delayed gravitational activation for momentum-prepared sources. If the environment monitors position, then position-prepared structure classicalizes quickly and becomes hard to use as a probe of the rendering process. It already matches the basis the environment reads out.But if you prepare the system in the complementary sector — here, momentum coherence — then the environment does not immediately convert that organization into redundant branch records.So momentum-sector coherence acts like a contrast agent for the rendering dynamics.That is what you call “super-momentum”
