Every hazmat-compliance scan HaulGuard records is locked into a SHA-256 hash chain.
This page fetches the chain's hashes (no driver data) and re-runs the verification
math in your browser using the Web Crypto API. If any record had been
removed, altered, or inserted post-hoc, the link breaks at that point and you'll
see a red X with the broken event. Don't trust us — let your own machine check.
