We count the number of CCSNRs in three mass ranges divided by the zero-age main-sequence mass, $M_{\\rm ZAMS}$; A: $M_{\\rm ZAMS} < 15\\ {\\rm M}_\\odot$, B: $15\\ {\\rm M}_\\odot < M_{\\rm ZAMS} < 22.5\\ {\\rm M}_\\odot$, C: $M_{\\rm ZAMS} > 22.5\\ {\\rm M}_\\odot$. Simple compilation of progenitor masses in the literature yields a progenitor mass distribution of $f_{\\rm A}: f_{\\rm B}: f_{\\rm C} =0.24:0.28:0.48$, where $f$ is the number fracti"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.03426","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"}
