In particular, our attempt will be to reconstruct the inflationary potential by constraining, $V(\\phi_0), V^{\\prime}(\\phi_0), V^{\\prime\\prime}(\\phi_0), V^{\\prime\\prime\\prime}(\\phi_0)$ and $V^{\\prime\\prime\\prime\\prime}(\\phi_0)$, in the vicinity of the field, $\\phi_0\\ll M_p$, and the field displacement, $\\Delta \\phi \\ll M_p$, where $M_p$ is the reduce"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1403.5549","kind":"arxiv","version":2},"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"}
