We use data collected in the CLEO-c detector from $e^+e^-$ annihilations delivered by the Cornell Electron Storage Ring with a center-of-mass energy near 4170 MeV. We find $\\mathcal{B}(D_s \\to \\phi e \\nu)~= (2.14 \\pm 0.17 \\pm 0.09)$%, $\\mathcal{B}(D_s \\to \\eta e \\nu)~= (2.28 \\pm 0.14 \\pm 0.20)$%, and $\\mathcal{B}(D_s \\to \\eta' e \\nu)~= (0.68 \\pm 0.15 \\pm 0.06)$% for the largest modes, where the first uncertainties are statistical and the second are systematic. We also obtain $\\mathcal{B}(D_s \\to K^0 e \\nu)~= ("},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1505.04205","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"}
