Paper 15 of the Holographic Cosmology Series. When tile tilt reaches θ = π/2 (event horizon), bandwidth vanishes and continued information influx forces a pinch-off: the sub-horizon membrane detaches as a baby universe inheriting K = 256 ln (2) /9 and ν = 13/36. The parent heals tile-by-tile via mechanical Hawking radiation, culminating in a final energy flash E = K · EPlanck.
