The Half Power That Cancels Itself: I Priced the Fixed n = 1/2 in the k-Essence Wormhole Sources, and It Is the One Power Where the Kinetic Term Drops Out

Prices Queue-2 item Q2-03, arXiv:2512.11018 (Silva et al., matter sources for wormholes in k-essence theory), on its verified abstract and full-text Sec. II. The load-bearing step is the fixed power n = 1/2 in F(X) = F0 X^n - 2V(phi), adopted in all three models: from the paper's own eqs. (15) and (18), -F/2 + X F_X = F0 X^n (n - 1/2) + V, so at n = 1/2 and only there the kinetic term cancels out of that combination exactly, and the same power is the unique one at which phi' is linear in Sigma''/Sigma. What the fix buys is the paper's analytic programme; its cost is scope -- every constructed source is an n = 1/2 source, selected by no premise in the text. INCREMENTAL. Quantum gravity NOT SOLVED; vacuum catastrophe NOT SOLVED.
