The flow near the singularity separates into two phases. A first phase is within a tubular region that shrinks as a power-law (t_c-t)^ν, with t_c the blow-up time, where the helicity is focused. This region is separated by a sharp interface from an outer region where the vorticity, and thus helicity, is identically zero.","weakest_assumption":"The assumption that a Leray-inspired self-similar velocity field permits an exact separation of variables that reduces the full Euler PDEs to a closed nonlinear ODE system whose solutions accurately capture the local structure of any actual finite-time singularity."}},"verdict_id":"296a6d2b-bc47-4163-b4c5-4d16f30e2719"}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:3dd1f77be0c13b0e940c3a817984be63ca47c919120e343ad6fe3431ffb1a122","target":"record","created_at":"2026-05-20T00:04:46Z","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":"e46004a394aeaee9c6107ed1c7128f60a41135b7cca6a83a03421b1a648069ad","cross_cats_sorted":[],"license":"http://creativecommons.org/publicdomain/zero/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2026-05-17T17:58:39Z","title_canon_sha256":"51d57dce25bd0ef2d8546a0ed69754f313ae50ad6cebe6f00c62e8d4d6dcbd15"},"schema_version":"1.0","source":{"id":"2605.17569","kind":"arxiv","version":1}},"canonical_sha256":"cb316bc3571a5ab613257d8be7c02c841f62f45dd7408b0b3b8d796eddf05237","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cb316bc3571a5ab613257d8be7c02c841f62f45dd7408b0b3b8d796eddf05237","first_computed_at":"2026-05-20T00:04:46.438925Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-20T00:04:46.438925Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"adyMN882SKo7ysdxVV5ypAWHg6TBfJRjmic5XNduV7M7gmqVdvd8d523haVaEQDqTX/ck+AIwMfWMCUZvu+MAg==","signature_status":"signed_v1","signed_at":"2026-05-20T00:04:46.439755Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.17569","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3dd1f77be0c13b0e940c3a817984be63ca47c919120e343ad6fe3431ffb1a122","sha256:dc7b8ce09c1976a4f4e785cb442c67a0b6d2e9fd0ed7dcdb5fc474d4532adb8b"],"state_sha256":"11aa1e9a9f540fe8bcb700f12fecb08e31aba84907ceb96229b2166e5c2f0a6c"},"bundle_signature":{"signature_status":"signed_v1","algorithm":"ed25519","key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signature_b64":"Lrzp+uyeRQXX+qlvNAgDGncCixJYoN6S1QbCVLSJMq/GMVv4iMcdEDKoNKzlzxFO8fnrjnwtJZT8H1G5nygwDg==","signed_message":"bundle_sha256_bytes","signed_at":"2026-05-31T18:22:46.922469Z","bundle_sha256":"174f9476d2fb25be2050b92a0c7a45712d5a7d9608926ba296e5e92398c8bbf8"}}
