Synapse archive

The dated snapshot is stored in the Universal Informatics Synapse project. All 15 files were retrieved and verified against their local SHA-256 hashes. The receipt records file identifiers, versions and provider timestamps.

Project access remains owner-only. This archive record is public; the stored research package requires an authorised Synapse account.

DeSci and IPFS

Universal Informatics — 26 October 2026 — 43d49bbc4b88 is stored as a private DeSci draft. Each of its 33 archived files has an IPFS content identifier independently recomputed from the exact local bytes and matched to the provider’s stored file tree.

The complete CSV is preserved as ordered 8 MiB segments to meet the upload limit. The storage map records their order and hashes; concatenating those segments recovers the original compressed CSV byte for byte.

Publication state: Private draft; no public signed publication has been made.

The combined archive manifest has been recovered and stored through DeSci’s supported draft-update API. Its CID was independently recomputed from the saved manifest bytes. The reconstructed directory CID matches DeSci’s stored 33-file directory.

DeSci’s live document editor still reports a missing document reference. The archive manifest and files are intact; editor-service restoration remains a provider issue. A repair request was submitted to DeSci support on 26 October 2026 and receipt was confirmed. Restoration remains pending their response. No signed public DeSci publication has been made.

Verified timestamp

DigiCert signed the manifest hash at 26 October 2026, 10:29:52 am Sydney time (25 October 2026, 23:29:52 UTC). Verification passed for the signature, certificate chain, original request nonce and exact manifest bytes, using an independent system CA trust store.

The manifest binds the archived files to that timestamp. This establishes evidence of existence and integrity at the recorded time; it does not assess scientific validity or determine legal ownership.
