This Zenodo record contains the main preprint “Eid's Covenant: A Unified Adelic–Phase–Xi Program for the Riemann Hypothesis” together with a supplementary technical note. The main manuscript develops a unified research architecture around the Riemann Hypothesis, while the supplement sharpens several bridge lemmas concerning the adelic trace layer, the canonical tail phase, spectral entire reconstruction, average phase discrepancy, logarithmic tail corrections, and Gaussian mollification.
