The extension is performed by modifying the path on which the distribution function $f_{\\mathbf{k}}$ is taken towards local equilibrium $f_{0\\mathbf{k}}$, by replacing $f_{\\mathbf{k}} - f_{0\\mathbf{k}}$ via $f_{\\mathbf{k}} - f_{{\\rm S}\\mathbf{k}}$. The Shakhov-like distribution $f_{{\\rm S} \\mathbf{k}}$ is constructed using $f_{0\\mathbf{k}}$ and the irreducible moments $\\rho_r^{\\mu_1 \\cdots \\mu_\\ell}$ of $f_\\mathbf{k}$ and reduces to $f_{0\\mathb"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2401.04017","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":""},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2401.04017/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"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"}
