  "long-description": "SPARK-proved BLAKE3 hash function for Ada 2022. Implements the C2SP BLAKE3\nspecification with hash, keyed_hash, and derive_key modes. Compression\nfunction, G function, byte conversions, chunk processing, and CV-stack\nMerkle assembly are formally verified at SPARK level 2: 482/482 proof\nobligations discharged, zero unproved VCs, zero pragma Assume. The\nBLAKE3 algorithm-level invariant relating CV-stack depth to the chunk\ncounter (popcount bound) is a machine-checked theorem, and the\n2**64-byte input cap is an enforced precondition (see SECURITY.md).\n\nNo heap allocation, pragma Pure, suitable for embedded and safety-critical\nsystems. Extensible output, incremental API (Init/Update/Final), comprehensive\nofficial C2SP test vectors.\n\nConstant-time execution is out of scope for this release. See SECURITY.md\nfor the full threat model.\n",
