The transition, encoded by a scalar interpolator along a timelike congruence, occurs on a codimension-one hypersurface where the continued metric is degenerate but curvature invariants remain finite, so the surface is curvature-regular. Using this covariant continuation, we rewrite the Einstein tensor of the continued metric as a localized, interpolator-dependent effective source for the post-transition Lorentzian branch, yie","authors_text":"Raghvendra Singh, Sergey Bondarenko","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"gr-qc","submitted_at":"2026-06-30T22:28:24Z","title":"Inflation from Covariant Signature Change: A Geometric Mechanism"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.01274","kind":"arxiv","version":1},"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:dd11a485e14af32269c9a83163717da496284b11fac2afb949b294a587391e15","target":"record","created_at":"2026-07-03T00:16:56Z","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":"d8335a3b7911e9372d4a11a259d2ea1cfef07b354384efda8fac7b04cb6a7c4d","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"gr-qc","submitted_at":"2026-06-30T22:28:24Z","title_canon_sha256":"fce07a326f5e546fadaff3b7792d8bc8b7663c8d0726f2eb3211ed2263ae44eb"},"schema_version":"1.0","source":{"id":"2607.01274","kind":"arxiv","version":1}},"canonical_sha256":"f825eec1b16dd299956a0b568618d7aefc5efd7f4abe6f424b692e94de0df8fc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f825eec1b16dd299956a0b568618d7aefc5efd7f4abe6f424b692e94de0df8fc","first_computed_at":"2026-07-03T00:16:56.011697Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-03T00:16:56.011697Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"GZjxiWlfiSJYxoSs4En5XS4YMKiviVF5Yc4wgc2exOYMO3gYr8RkRSkDsDgBmLLJCmHY1e7QqcJSs3t0/Qz9Ag==","signature_status":"signed_v1","signed_at":"2026-07-03T00:16:56.012073Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.01274","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:dd11a485e14af32269c9a83163717da496284b11fac2afb949b294a587391e15","sha256:25faa738d6531a9488f0ee67a65212c4e2bec6422d1b9ecce3c915c3e5b62d61"],"state_sha256":"5055c7436865020ce9bdda24fba54b9a17d9f8cad9afdbd2cb92001eadb6b7f5"}
