The void population runs empty-heavy: supervoids beyond 200 Mpc are roughly five times more abundant than ΛCDM simulations predict, with depths and sharp profiles that need fine-tuned feedback or bias to imitate (Tavasoli 2013; Sutter 2014). Gradual gravitational evacuation caps how large and empty a void can get, and the population ignores the cap.
Voids in the standard model are grown, not made: underdense Gaussian patches slowly evacuate under gravity, so their size and emptiness are rate-limited by the age of the universe. An overabundant population of large empty voids has no source except statistical tails that should be exponentially rare, the mirror image of the giant-wall problem.
SCT makes the voids simultaneously with everything else. The cascade deposited filaments along head-on event axes (P33) and clusters at their intersections, and the regions between the deposited streams are voids from the first moment (P34), not patches waiting billions of years to evacuate. Emptiness is the starting condition, so no evacuation rate is violated, and abundance follows the geometry of the cascade-stream network rather than the exponential suppression of Gaussian tails. The observed factor-of-five supervoid excess is the registered signature of this inversion: in a deposited web, large voids are typical architecture.
The M5 companion deepens them on schedule: inside underdensities the local binding term is weak, so Λ_eff runs enhanced (P17, P19) and the apparent expansion locally accelerates, evacuating void interiors faster than constant-Λ dynamics allow. The same enhancement makes voids loud in the ISW (recid 67, recid 89) and supplies the KBC void's registered share of the Hubble tension (recid 86). The architecture is laid out in Paper 1, From Chaos to Convergent Foundations, with the Λ_eff machinery in Paper 7, From Chaos To Cosmic Expansion. One family of premises carries the whole void sector: P33 and P34 for existence and abundance, P17 and P19 for depth and voice.
Nothing is tuned. The voids are not anomalies in the web; they are the gaps the web was built with.
DESI, Euclid, and SKA void censuses carry the kill: if the void size function converges on ΛCDM Gaussian-tail predictions, dissolving the factor-of-five supervoid excess into tracer systematics, the deposited-gap origin is refuted. The depth half is separately exposed: void interiors evacuating no faster than constant-Λ dynamics allow, measured through void density profiles and their ISW imprints, would remove the Λ_eff enhancement the M5 companion requires.
