We present pre-registered, cryptographically frozen structural predictions for CMS Run-3 dijet angular distributions (1/σ) dσ/dχ at 13.6 TeV, derived from the Discrete Emergent Universe (DEU) computational framework. Under a single published energy anchor (E24 ↔ 6.14 TeV) and a two-stage pre-registration protocol frozen before any profiling simulation existed, the model predicts: a pre-boundary excess accumulating at 1 < χ < 2 with a soft-wall deficit immediately above χ = 2 in the 7—8 TeV dijet mass bin; and, above 8 TeV, an inversion of the post-boundary deficit to a weak excess as the boundary softens and leaks, with the negative step S∗ and edge-log-drop ∆∗ persisting in both bins. All prediction values trace through SHA-256 hashes to simulation instruments certified row-exact against the archived output of the original DEU collision campaign. We additionally report the profiling ladder beyond the scored range, which exhibits a previously uncharacterized regime of simultaneous channel extinction, and an exploratory analysis of collision phenomenology versus foam age whose central qualitative claims are shown to be robust across a declared band of instrument-reconstruction uncertainties. Negative results obtained during the campaign are documented with the same prominence as positive findings.
