CNC x Pulsar Timing Array Holonomy Witness: Multi-ephemeris and multi-pipeline loop-closure test (Prereg artifacts and protocol, v1)

This Zenodo record archives the preregistered protocol and frozen parameters for an analysis-only study testing multi-ephemeris and multi-pipeline loop closure in public Pulsar Timing Array (PTA) timing data. OSF preregistration (registered): 10.17605/OSF.IO/5WTKH Contents: - Protocol paper (PDF) and LaTeX source - Preregistration pack (protocol, gates, reporting template, reproducibility checklist) - SHA-256 manifest for all files in this record Scope: - No new observations - Uses only public PTA releases. Raw PTA data are not redistributed here; the protocol specifies how dataset DOIs/URLs and file checksums will be recorded.
