The signed results are yours to check

Download them, verify them, cite them, republish them unmodified, and publish whatever you find. That is the whole point of signing them — if you cannot check the numbers without asking us, they are not evidence.

The proofline-verify tool is published for the same reason. It contains the verifier only; there is no detector in it.

The detector is not distributed

The Proofline engine — the feature extractor, the tokenizer, the model parameters — is proprietary and is not published here or anywhere else. Access to it comes through a commercial agreement.

Please don't

Pass off a modified or forged artifact as a Proofline result, or strip the signature off one and present the numbers as ours. The signature exists so that anyone can tell the difference; misrepresenting it defeats it.
