It introduces no new assumptions and fully adopts Postulates I–VI and the postulate-level laws L1–L5 of the parent paper, and follows the parent paper's format of "qualitative account—formula proof—conditions for verification." This paper uses only the formulas of the parent paper and the simplest algebraic expressions, and borrows no ready-made external formula.

First, according to Postulate VI and §1.7 of the parent paper, when the dynamic pressure at the front end of a high-speed accretion disk exceeds the neutralization-energy density of the vacuum, neutral quantum wells are indeed temporarily decomposed, the negative annihilation pairs diffuse away, and the positive annihilation pairs are temporarily retained; mechanistically, "the front end is producing positive annihilation pairs" holds. Second, whether these positive annihilation pairs can aggregate into stable positive quantum wells and then form nebular matter depends on a computable nucleation criterion—the front-end source term must overcome the linear decay term of the positive annihilation pairs. This paper further brings black-hole gravity into the energy budget: front-end production consumes the kinetic energy of the accretion disk, but the kinetic energy is continuously replenished by the release of the black hole's gravitational potential energy; gravity here is an "energy-supply pool," not something that "only swallows." At the same time, an important wording is clarified—neutral quantum wells have no net attraction, no net repulsion, and no tension grid with respect to one another, and cannot be "compressed"; what the black hole does is "modulate" the surrounding negative-quantum-well distribution so that the local spacetime as a whole becomes denser, with the neutral quantum wells caught up in it, while what the front-end dynamic pressure does is "open" rather than "squeeze smaller." Under the condition that the above criteria hold, the front end of a black-hole accretion disk is a nucleation environment of "local high density, high speed, and pre-existing nuclei"; unlike the slow accumulation from a diffuse state in the early universe, it produces matter in the manner of "decomposition—retention—in-situ nucleation." Whether it suffices for "a considerable part of galactic matter comes from production at the black-hole front end" to hold depends on a set of parameters to be calibrated (the neutralization energy ε_N, the number of neutral quantum wells per unit volume n_N, the positive-quantum-well aggregation coefficients α⁺/β⁺, the decomposition efficiency η, etc.); this paper gives the full criterion structure and testable predictions, and makes no numerical assertion.
