We use three different diagnostics; the ratio of stars to brown dwarfs as a function of distance from the region's centre, $\\mathcal{R}_{\\rm SSR}$, the local surface density of stars compared to brown dwarfs, $\\Sigma_{\\rm LDR}$, and we compare the global spatial distributions using the $\\Lambda_{\\rm MSR}$ method. From a suite of twenty initially statistically identical simulations, 6/20 attain $\\mathcal{R}_{\\rm SSR} << 1$ $and$ $\\Sigma_{\\rm LDR} << 1$ $and$ $\\L"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1403.7053","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"}
