Model Fingerprint

Content-addressable model hashing with blake3 and ed25519 digital signatures. Computes per-tensor and whole-model fingerprints, signs with Ed25519, verifies signatures, and detects single-tensor tampering.

Device:

cargo run --example analysis_model_fingerprint

Key concepts: blake3 hashing, ed25519 signing/verification, per-tensor checksums, tamper detection, provenance chain.
