  "abstract": "The Unresolved $γ$-Ray Background (UGRB) encodes the collective emission of source populations that are too faint to be detected individually, and its cross-correlation with tracers of the large-scale structure has emerged as a powerful tool to characterize those populations. In this work, we analyze the weak-lensing--UGRB cross-correlation using a reference blazar model. By modeling the relation between blazar $γ$-ray luminosity and host-halo mass, we infer the average linear bias $\\langle b(z) \\rangle$ and host-halo mass $\\langle M(z) \\rangle$ of the unresolved blazar population. We find that the signal is dominated by moderately biased sources, with $\\langle b \\rangle \\gtrsim 2$ at $z\\simeq 1$, hosted by halos with $\\langle M \\rangle \\sim \\mathcal{O}(10^{13}\\,M_\\odot)$. Repeating the analysis with a misaligned-AGN model yields consistent bias values, indicating that the result is determined by the clustering properties of the UGRB rather than by the details of the $γ$-ray source model.",
