Wavefunction Prediction Does Not License a Photon Path - A Short Interpretive No-Go

This paper makes one narrow interpretive no-go claim. The mathematical success of the wavefunction in predicting lawful absorption outcomes does not license the conclusion that a photon follows an intermediate spacetime path between endpoints. For the photon, relativistic null structure withholds the ordinary timelike template of internal duration, traversed route, and lived intermediate history. The wavefunction may assign amplitudes and outcome weights for lawful absorption events without thereby describing where the photon is in between. The paper does not revise quantum mechanics, alter quantum field theory, or introduce a new dynamical law. It argues instead for interpretive restraint: predictive success does not by itself warrant transit ontology. Interference cases are included within the same restriction. The note is framed as a short application of earlier work on null proper time, the absence of a photon rest frame, and the rejection of carrier-based readings of null curves. What is preserved is the full predictive machinery of standard theory. What is removed is only the unlicensed inference from wavefunction prediction to an intermediate photon path.
