Substantiation surface: the statement traces to every supporting record with contradictory, incomplete and missing evidence in the same view. A claim is never shown without them.

This workspace never shows: a supplier ranking, a generic sustainability score, an automatic compliance verdict, or a hidden favourable-evidence filter. A claim is never shown without its contradictory and missing evidence. Environmental measures are never collapsed into one score. Proof preserves evidence; it doesn't certify suppliers or validate claims. k=5 throughout.
