This supplementary material contains detailed methods, audit plans, protocol amendments, results ontologies, and supporting outputs associated with the Stage IV cryptographic audit validation study. It includes no discussion or interpretation and is intended to function as a standalone technical record enabling independent inspection of study design, execution lineage, and reported results. All documents are provided as rendered representations of cryptographically anchored canonical artefacts, with provenance information disclosed where applicable.
