 ## Numerical model fingerprint assets
 
 The embedded bank and scorer in `pkg/model_fingerprint` are from [gpt-model-check](https://github.com/Katao123/gpt-model-check), commit `3d6716a0903cf061daea001d5d44ee410846634e`, using the ModelTrace bank dated 2026-09-05. The upstream gpt-model-check, ModelTrace, and is-gpt-nerfed MIT notices are included alongside the sources and under `/licenses/model-fingerprint/` in the image. Relative candidate weights are not calibrated identity probabilities.
