pip install confium

from confium import signatif

result = signatif.verify_trusted_artifact(
    artifact,   # dict: the trusted artifact
    bundle,     # dict: the trust anchor bundle
    graph,      # dict: the trust graph
    registry=cnml_registry,          # dict or None for defaults
    transparency_included=True,
    time_anchored=True,
    time_attested_at="2026-08-18T09:00:00Z",
    accepted_labels=["verified", "attested"],
)

if result["accept"]:
    print(result["label"], result["coverage"]["dimensions_verified"])
