CIB cross-correlations fit ΛCDM halo models only through tuned bias, redshift, and efficiency dials, and two residuals survive the tuning: excess large-scale power and a coherence with the X-ray background stronger than known shared populations explain (Cooray 2012; Viero 2013; Kashlinsky 2018). The unresolved glow is making the same complaint as the resolved JWST galaxies.
The model's CIB is the dust echo of feedback-regulated star formation in hierarchically grown halos, so its power spectrum and cross-correlations are fixed once the assembly history is. Residual large-scale power and excess background coherence require sources earlier, more clustered, or more accretion-luminous than that history can supply.
SCT's early universe was busy from deposition. Collision-seeded proto-structures carried dense reservoirs at birth (P22, P25), igniting star formation and dust production when the gas cooled rather than when halos assembled, the same accelerated start carrying the JWST mass crisis (recid 107) and the early star formation history (recid 111). The CIB inherits both residuals from that start: extra power at large angular scales because the seeded populations cluster on the deposited web's geometry (P34), coherent over the scales the cascade organized rather than the scales gravity had time to correlate; and stronger background coherence because the same deposits that formed stars also fed seeded black holes (P46), so the dusty glow and the accretion glow share sources at a depth standard demography cannot match.
The reading makes the unresolved and resolved evidence one statement: the background residuals are the integrated light of the same collision-seeded epoch JWST is now resolving object by object, with the registered expectation that deeper source-subtraction pushes the residual coherence to higher redshift rather than dissolving it. The seeding mechanics are in Paper 4, From Chaos To Collisothermal Cosmogenesis, with the early chemical maturity companion at recid 113 supplying the dust on schedule.
Keystone economy: P25 starts the glow early, P34 clusters it, P46 makes it coherent with the X-rays. Three residuals, one deposit.
Deep source subtraction carries the kill: if Euclid, Roman, and JWST progressively resolve the CIB into standard galaxy populations, with the large-scale excess and X-ray coherence dissolving into known sources and tuned halo models converging without residue, the seeded-epoch contribution is unnecessary. SCT separately requires the residual coherence to persist and to localize at high redshift as resolution improves; a residual that localizes at low redshift, tracing ordinary foregrounds, would refute the early-deposit origin.
