We find five phenomenologically interesting mixing patterns for which one column of the PMNS matrix is $(\\sqrt{\\frac{5+\\sqrt{5}}{10}},\\frac{1}{\\sqrt{5+\\sqrt{5}}},\\frac{1}{\\sqrt{5+\\sqrt{5}}})^{T}$ (the first column of the golden ratio mixing), $(\\sqrt{\\frac{5-\\sqrt{5}}{10}},\\frac{1}{\\sqrt{5-\\sqrt{5}}},\\frac{1}{\\sqrt{5-\\sqrt{5}}})^{T}$ (the second column of the golden ratio mixing), $(1,1,1)^{T}/\\sqrt{3}$ or $(\\sqrt{5}+1,-2,\\sqrt{5}-1)^{T}/4$. The three lepton mixing angles are determined in t"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1503.03711","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"}
