These hyperfluids encode the microstructure of matter including shear, dilation, and spin via the hypermomentum tensor. In this paper, we focus on the observational constraints of the recently introduced Yano-Schr\\\"odinger hyperfluid, which sources a special type of nonmetricity, that preserves the lengths of vectors under autoparallel transport. We propose a model in which the effective nonmetricity contributions to pressure and matter density are related linearly as $p_{\\","authors_text":"Himanshu Chaudhary, Saddam Hussain","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2025-03-29T15:12:32Z","title":"Yano-Schr\\\"odinger Hyperfluid: Cosmological Implications"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2503.23115","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:06fd3641f941b44d07c2e02decb7337c22ac757e67ffa417796d1924dfbed375","target":"record","created_at":"2026-07-05T11:52:19Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"8fb52c470f45a2fd96b3ae76772000f7efa7e53fe1a19738c340028fb447dc75","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2025-03-29T15:12:32Z","title_canon_sha256":"0bb2ae980f17b0c53bb97cbf9f8c0fd0f3ef8f1624e0c8697065d51ea315b96a"},"schema_version":"1.0","source":{"id":"2503.23115","kind":"arxiv","version":2}},"canonical_sha256":"5729a35a2f1a3eddf8b4477bde27fdfc91c2ff8774b519cd12abe6125ae68619","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5729a35a2f1a3eddf8b4477bde27fdfc91c2ff8774b519cd12abe6125ae68619","first_computed_at":"2026-07-05T11:52:19.212589Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:52:19.212589Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XFSzBPvV1dsUi3Gd21WyJnG74y9mEJSY4owDcu5aT2H9Yd7YFBaPANjGizzO8W68aZ66SwnyKe78LMMo9AImDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T11:52:19.213216Z","signed_message":"canonical_sha256_bytes"},"source_id":"2503.23115","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:06fd3641f941b44d07c2e02decb7337c22ac757e67ffa417796d1924dfbed375","sha256:a4cf285edff19eb91ba6e7e1725f10d397f8262fc4bcd2011c9caafe1eb7ba1a"],"state_sha256":"d298b8435d9da55e800648675c4234686706db65f3aebc0023f3886c554f9350"}
