One baryon per billion photons survived the great annihilation, and the Standard Model cannot say why: its CP violation runs eighteen orders of magnitude short, its sphalerons act too gently in a smooth thermal universe, and its electroweak transition is a crossover, not the violent stage baryogenesis needs (Sakharov 1967; Cohen 1993). Every repair imports unconfirmed physics.
The hot Big Bang is smooth, thermal, and isotropic, which is precisely the environment in which Sakharov's conditions starve: equilibrium suppresses the asymmetry-building, isotropy provides no preferred handedness, and the Standard Model's CP violation was never sized for the job. The deficit is the initial condition's, not the particle content's.
SCT replaces the smooth thermal origin with a violently directional one, and all three Sakharov conditions feed at once (P41). Out-of-equilibrium: the superluminal intersection is the extreme non-equilibrium environment by construction, shock thermalization rather than gentle expansion (P22). Baryon number violation: sphaleron rates are exponentially enhanced in that shock environment, far beyond their thermal-universe gentleness. And CP violation, the eighteen-order deficit, is closed geometrically: the collision's angular momentum J = μ(b × v_rel) defines a preferred spatial axis distinguishing left from right in the collision plane, an effective CP-violating term of magnitude near 10⁻² to 10⁻³ against the CKM's 10⁻²⁰, amplification by nearly eighteen orders without one new particle.
The output lands on the measured number: the geometric mechanism produces η_B near 6 × 10⁻¹⁰, matching the Planck-calibrated asymmetry. The same J vector doing this work is the most-read object in the framework, the deposited axis behind the satellite planes, the quasar alignments, and the CMB anomaly axes, here acting once more at the particle scale. The mechanism is laid out in Paper 1, From Chaos to Convergent Foundations, with the falsification ledger in Paper 10, From Chaos To Confirming Falsifiability.
Keystone economy: P41 alone carries all three Sakharov conditions, with P22 supplying its environment. Matter exists because the origin had a handedness.
Two registered exposures. A confirmed laboratory demonstration of baryogenesis through a beyond-Standard-Model mechanism, leptogenesis signatures or detected heavy right-handed neutrinos carrying the observed asymmetry, would make the geometric channel unnecessary. And the geometry itself is testable: the mechanism ties the asymmetry to the collision J axis, so precision measurement of spatial variation in η_B incompatible with geometric production from a single deposited axis would refute the M8 reading directly.
