A real read — read offline against the base, never run. The verdict is reproducible.

    reads Sigstore signature bundles

    verifying a cryptographic provenance signature over model files; it can only attest what a publisher signed.

    requires a published Sigstore bundle; no scanned model ships one

1 off-the-shelf tool could read this model’s serialized files, and none flagged it. None of them reads what the weights mean: they hunt load-time code-execution, repo smells, or a provenance signature — real jobs, none of which is weight-level tampering. 3 other tools had nothing of the kind they read here. Vulcora reads the weights — offline, and never runs the model.

Couldn't reach the attestation service to re-verify just now.

Think this verdict is wrong?

Signed-in users can formally refute a read — Vulcora re-reads the model against your claim and records the outcome. You'll need an account to file one.

Refutations are actor-gated — a guest can't file one.

Cited in a research corpus

someone else’s label — not Vulcora’s live verdict

This model appears as a labelled specimen in a public benchmark corpus. Each panel below states the benchmark authors’ own published ground-truth label and, where the research harness actually ran, its coarse readout — distinct from the Vulcora verdict above.
