(i) Using cohomological techniques, we explore the consistent deformations of linearized conformal gravity in 4 dimensions. We show that the only possibility involving no more than 4 derivatives of the metric (i.e., terms of the form $\\partial^4 g_{\\mu \\nu}$, $\\partial^3 g_{\\mu \\nu} \\partial g_{\\alpha \\beta}$, $\\partial^2 g_{\\mu \\nu} \\partial^2g_{\\alpha \\beta}$, $\\partial^2 g_{\\mu \\nu} \\partial g_{\\alpha \\beta} \\partial g_{\\rho \\sigma}$ or $\\partial g_{\\mu \\nu} \\partial g_{\\alpha \\beta} \\partial g_{\\rho \\sigma} \\partial g_{\\gamma \\delta}$ with coefficients t"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/0106065","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
