LiVellum is an autonomous evidentiary infrastructure engine designed for institutional research repositories and civil court litigation. We detect link-rot, content drift, and dead datasets, freezing contemporaneous reality into cryptographically verifiable, permanent archives.
Whether preserving 20-year-old doctoral datasets across university archives or securing court trial bundles against judicial strike-out, LiVellum provides automated cryptographic permanence.
Over 60% of external URLs cited in doctoral theses vanish within 5 to 10 years. We audit institutional repositories (DSpace, EPrints, Pure), trace dead links through Memento federation, CrossRef DOIs, and Software Heritage SWHIDs, delivering 1-click XML remediation patches.
Harvard Law confirmed that 50%+ of URLs in judicial opinions and 70%+ in legal journals are broken or drifted. In UK civil litigation (CPR Part 32), submitting dead links or unverified web exhibits risks cross-examination humiliation or evidence exclusion.
How LiVellum rescued a £14.8M Commercial Court breach-of-warranty action 72 hours prior to the Pre-Trial Review (PTR) after 73 digital exhibits suffered catastrophic link-rot and silent content drift.
Four weeks before trial, Defendant's Leading Counsel brought an emergency application to strike out the Claimant's primary misrepresentation evidence under CPR 32.1, arguing that hyperlinked exhibits were uncorroborated hearsay that redirected to 404s or spam. Instructing solicitors faced severe wasted-costs exposure.
LiVellum ingested the electronic trial bundle, federated temporal crawling across the UK Web Archive (UKWA), Internet Archive CDX, and passive DNS history, isolating contemporaneous snapshots matching the exact warranty execution dates (2021–2023). Assets were encapsulated into ISO 28500 WARC containers, SHA-256 hashed, stamped with RFC 3161 timestamps, and certified under Section 8 of the Civil Evidence Act 1995.
