OMNI-1: The Threefold Witness — Spatial, Temporal, and Contextual Nonclassicality Witnesses Bound Into One ExecutionProof Governance Record

OMNI-1: The Threefold Witness A preregistered demonstration of three independently evaluated nonclassicality witnesses — spatial (Bell-CHSH), temporal (Leggett-Garg K3), and contextual (Peres-Mermin) — bound into one chain-linked, independently reconstructable ExecutionProof governance record. Framework: Coherent Inheritance Framework (CIF) Organization: Remnant Fieldworks Inc. Backend: IBM Quantum ibm_kingston (Heron r2, 156 qubits) Job ID: d9e3064jeosc73fi98e0 Hardware Results: Spatial (Bell-CHSH): S = 2.797 @ 17.82σ → VALID_ABOVE ✓ Temporal (Leggett-Garg): K3 = 1.502 @ 12.96σ → VALID_ABOVE ✓ Contextual (Peres-Mermin): χ = 5.126–5.282 (state-independent) → VALID_ABOVE ✓ Aggregate ExecutionProof Verdict: ALLOW omni_certified: True record_hash: fcc409ddcee8774586c3437c52ca3925cde25b4afa2562f3836a922644dd7def Independent verification: PASS (all witnesses reconstructed, verdicts agree) Scope: Results apply within the tested circuit model, backend, qubits, calibration, shot counts, software harnesses, and stated experimental conditions. This is an experimental evidence record, not a universal security proof or production certification. Device-dependent; Bell locality + detection loopholes open; Leggett-Garg relies on NIM assumption (clumsiness loophole open); contextuality compatibility loophole open. Version 1.1 (correction / erratum, 2026-07-18): This version issues a transparent, clearly-labeled correction (ERRATUM-OMNI-1.md) of six inconsistencies between the narrative files and the canonical machine record. Corrected: executed shot count (52,000 total; A 8,000 / B 8,000 / C 36,000, matching the locked harness), the canonical OMNI nonce (f6fa824c...), a single canonical contextuality significance (n_sigma_min = 20.5579; fabricated per-state sigma values withdrawn), a K3-vs-quantum-maximum clarification (1.502 consistent with the ideal 1.5 within measurement uncertainty), removal of two overclaims ('world's first' and 'bulletproof'), and disclosure of a v1.0 qubit-mapping logging defect. No measured value, verdict, or the aggregate ALLOW changed. The as-locked preregistration/harness (MANIFEST) and the hash-sealed ProofRecord JSON are preserved unedited.
