String Wakes and Seeded Structure at Capped Tension: Infall Velocities and the Largest Perturbation a Wake Can Grow

This paper computes a consequence of the torsion-regulated bounce for topological defects, using the density ceiling of 9.718e+54 grams per cubic centimetre and the maximum temperature of 3.278e+22 kelvin that follows from it. The velocity impulse at the capped tension is 9.444e-11 metres per second, with v gamma = 5.774e-01 at the stated network velocity. That is the entire dynamical endowment of a wake in this cosmology: matter is nudged at well under a millimetre per second. A wake laid down at recombination spans a horizon length of 3.598e+21 metres, but the overdensity it can assemble from such a kick remains utterly negligible after the growth of structure is applied, because growth multiplies a perturbation; it does not create one. To deliver a kick of ten kilometres per second, modest by the standards of structure formation, the tension would need to be 4.598e-06, some fifteen orders of magnitude above the ceiling. String wakes in this framework seed nothing: no galaxies, no sheets, no voids. Structure formation here must proceed, as in the standard account, from the primordial fluctuations themselves, with defects playing no dynamical role at any epoch. The calculation is performed from stated assumptions with all arithmetic deposited, and it is a computation, not a measurement.
