Integrity and machine-readable records
The preservation manifest records every OSF identifier, original materialised path, byte size, timestamps, source URL, MD5 and SHA-256 value published by OSF. All 359 mirrored files passed a local SHA-256 comparison with the source manifest on 1 September 2026. The manifest is suitable for independent verification and rebuilding the directory tree.

Scientific boundary
The archive documents an active research programme. A file’s presence does not prove that every instrument, phone, campaign or proposed application met the study targets. For an interpreted evidence summary, use the iSPEX2 research and publications page. For current availability, use the iSPEX status page.
