Pay-per-Training-Provenance: an agent pays to seal the provenance of a dataset or training run — a C2PA-compatible manifest binding the dataset/artifact hash to a declared origin, served with a post-quantum ML-DSA-65 / Dilithium-3 (NIST FIPS 204) signature over the same canonical claim (manifest anchor: Dilithium-3). Built for EU AI Act Art. 10/53 training-data provenance. Privacy-preserving (only the hash is bound). x402-native.
