What This Does Not Do

Model the actual black-hole formation history. The constant-feeding approximation is a first step; the real history (peaked at z ≈ 2, declining since) would modify the predicted epoch dependence and tighten the result. The 1.2% dark-matter error likely comes from this approximation. D48 covers it.

Derive the equation of state. Dark energy’s intrinsic state is w = −1 (cosmological-constant behaviour) because the fully-defragmented state is the substrate at rest; the effective w_eff(z) departs from −1 because the reservoir is sourced (section 4.3). The intrinsic value has not been formally derived from the axiom system, and the crossing redshift of w_eff awaits the feeding-rate history (D48). KS-42.4 carries the test.

Explain dark-matter substructure. Whether defragmenting substrate forms halos, and with what density profile, requires the detailed dynamics of the defragmentation process, not computed here.

Close D44 fully. This paper addresses D44 by deriving the timescale and predicting the epoch dependence. Closing it completely requires the full formation-history convolution (D48) and observational confirmation of the epoch dependence (KS-42.2).
