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.

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.
