CROVIA is a public evidence system for AI training provenance.

\n

It records timestamped observations of evidence presence and evidence absence.

\n

All artifacts are queryable via public endpoints and reproducible from raw evidence.

\n

This page shows a live artifact. It is not a demo.

\n

Beyond observation, the system performs behavioral forensics on model weights and dataset attribution analysis — evidence that goes deeper than what models disclose.
