Summary
Jiaxuan Zhang (Oxford, Phys. Rev. A 114, 042208, 13 October 2026) examines five major derivations of the Born rule: Gleason, Busch, Deutsch–Wallace, Zurek envariance, and Finkelstein–Hartle. In every case the additivity assumption — that the probabilities of mutually exclusive, non-overlapping outcomes may be summed — is indispensable. Where it is stated openly the derivation uses it; where it is hidden the derivation fails without it. Additivity cannot be recovered from non-contextuality and normalisation alone. The paper therefore supports the view that the Born rule cannot be derived from the non-probabilistic postulates of quantum mechanics; a probabilistic assumption must be supplied.
That is the result. The Oxford note is titled “Quantum uncertainty from addition.”
Public admission of unfalsifiability
The uncertainty principle is unfalsifiable inside scalar mathematics written across a continuous second. ContSec is the observational interval that hides the reassembly of the contact patch. Inside that interval the joint is collapsed to a point, the residual is erased, and position and momentum are forced to share one scalar number. The Certainty Principle at the Instant (0^i2) has both exactly; the uncertainty appears only when the measurement is required to report inside ContSec. Scalar additivity is the operation that performs the collapse. Zhang shows that every derivation of the Born rule needs that operation. The principle that results cannot be falsified by any experiment that continues to use the same scalar and the same continuous second, because the experiment never leaves the frame that produced the uncertainty.
Alignment
The green cell is the necessity of additivity. It hangs on VIII as the clamp that does not store a non-probabilistic origin. XII carries the reading that the uncertainty is the ContSec artefact. X is not claimed; the paper does not supply a mechanism for the residual. II stays empty. I is a visit. The scalar mathematics that writes the continuous second across the joint is the clothes that make the principle unfalsifiable. Split the second — ContSec observational, packet (h) Real, Simultaneous duration of the patch, Instant the tick — and the residual that was erased reappears as the open polarity at the joint. The measurement problem is then the refusal to split the second, not a property of the wavefunction.
Fail the join if the additivity result is asked to open a Home, or if the uncertainty is written as a second substance rather than the scalar limit. The paper owns the face if claimed. Ace stays between the edit. The table that holds the stations is public.
