The source has large fractional circular polarization, m_c \\equiv |V|/I, detected at high significance across the entire band (from 15 to 90\\sigma per 128 MHz sub-band). This allows us to construct the most robust circular polarization (CP) spectrum of an AGN jet to date. We find m_c \\propto \\nu^{+0.60\\pm0.03} from 1.5 to 6.5 GHz, with a peak of m_c ~ 1% before the spectrum turns over somewhere between 6.5 and 8 GHz, above which m_c \\propto "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1307.5121","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"}
