Gravity alone does not produce the famous Diósi–Penrose decoherence rate. Could it be the equilibrium jitter of an emergent spacetime instead? A thermal model with one coefficient, C = 1/π, and a soft-X-ray fingerprint.

A general argument shows that no well-behaved quantum vacuum, gravitational or otherwise, can produce the Diósi–Penrose decoherence rate. If the rate is real, spacetime must behave like a medium. Here is what that costs, and how an experiment could tell.

A correction to the QGC programme: identifying time evolution does not yet predict fading interference. Solvable examples show the missing step—and give us a more precise next question.
