Deterministic Post-Export Verification (Public Record)

This page summarises the publicly disclosed reproducibility record and points to the independent artefacts required to reproduce reported results. Ordinal 15 is a pre-registered disclosure integrity test demonstrating deterministic PASS/FAIL outcomes under a hash-only, zero-custody model.

View Ordinal 15 (Zenodo)CRO Quickstart & Verification Model

The disclosed record is zero-custody: no raw evidence is published. Verification uses only cryptographic identifiers and public anchoring receipts. PASS indicates cryptographic equivalence to a reference state; FAIL indicates enumerated divergence. Neither implies misconduct or regulatory non-compliance.

Stage IIIB and Stage IV verification overview (context figure)

Ordinal 15 — Disclosure integrity (primary)

Ordinal 15 evaluates whether a disclosed post-analysis state matches its anchored ground truth using deterministic, hash-only paired comparison. The test is designed to be independently inspectable and does not require access to execution environments or raw evidence.

Node02: anchored truth (A) vs disclosed state (B) — expected FAIL with explicit enumeration (missing / extras).
Node03: anchored truth (A) vs disclosed state (B) — expected PASS (cryptographic equivalence).
Output artefacts are hash-only summaries and deterministic diff lists (no filenames, no paths).

See the Ordinal 15 summary artefacts under Documentation / Guide and the anchoring receipts under Anchors.

Reproduction pathway (public)

Stage IIIB & Human Verification Time (HVT) — Context

Stage IIIB and HVT measurements are included as historical validation context for the broader programme. The Q2 2026 CRO Audit Trial focuses on post-export verification outcomes and does not require any specific tamper regime.

Verification outcomes remain deterministic. PASS and FAIL indicate cryptographic equivalence or divergence relative to a reference state and do not assert semantic correctness or intent. Interpretation and disposition remain the responsibility of CROs, sponsors, and regulators.
