This theory extends the Brans-Dicke and scalar-tensor models within the symmetric teleparallel formalism. We consider a nontrivial connection that allows for genuinely nontrivial solutions in the limit of General Relativity. The field equations admit a minisuperspace description and by applying the method of variational symmetries we construct the corresponding conservation laws in vacuum. The application of these conservation laws enables the reco"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"The symmetric teleparallel scalar-tensor theory supports the existence of viable astrophysical objects, demonstrated by constructing interior solutions matched to an extremal Reissner-Nordström exterior.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"The assumption that a nontrivial connection can be chosen such that the theory reduces to a genuinely nontrivial limit of general relativity while still admitting analytic solutions via the minisuperspace reduction and variational symmetries (invoked in the abstract when stating that the field equations admit a minisuperspace description and that conservation laws enable reconstruction of analytic black-hole solutions).","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Analytic black-hole solutions are reconstructed via conservation laws from variational symmetries in symmetric teleparallel scalar-tensor gravity, and the theory is shown to support viable compact-star interiors matched to extremal Reissner-Nordström exteriors.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Symmetric teleparallel scalar-tensor gravity supports viable compact stars through interior solutions matched to extremal Reissner-Nordström exteriors.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"3af1d0b2ecfce089fea210aec4d372c6e67c4c17a7b4ed4c2c6cd91801893139"},"source":{"id":"2510.17066","kind":"arxiv","version":2},"verdict":{"id":"0760d473-970d-4b7d-8651-cf2e84228ef7","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-18T06:46:10.937236Z","strongest_claim":"The symmetric teleparallel scalar-tensor theory supports the existence of viable astrophysical objects, demonstrated by constructing interior solutions matched to an extremal Reissner-Nordström exterior.","one_line_summary":"Analytic black-hole solutions are reconstructed via conservation laws from variational symmetries in symmetric teleparallel scalar-tensor gravity, and the theory is shown to support viable compact-star interiors matched to extremal Reissner-Nordström exteriors.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"The assumption that a nontrivial connection can be chosen such that the theory reduces to a genuinely nontrivial limit of general relativity while still admitting analytic solutions via the minisuperspace reduction and variational symmetries (invoked in the abstract when stating that the field equations admit a minisuperspace description and that conservation laws enable reconstruction of analytic black-hole solutions).","pith_extraction_headline":"Symmetric teleparallel scalar-tensor gravity supports viable compact stars through interior solutions matched to extremal Reissner-Nordström exteriors."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2510.17066/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"references":{"count":72,"sample":[{"doi":"","year":2004,"title":"Tegmark et al., Astrophys","work_id":"992867e7-8fbe-4ed2-b209-382595271b93","ref_index":1,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2008,"title":"Kowalski et al., Astrophys","work_id":"05bd7607-eef4-4393-8aa3-217dddce5a8e","ref_index":2,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2009,"title":"Komatsu et al., Astrophys","work_id":"bec58dff-cb1e-4612-bf8a-1b3a66afd64f","ref_index":3,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2012,"title":"N.
