szl-guardrail-receipt
Copyright 2024 SZL Contributors

This product wraps guardrail verdicts into signed, hash-chained decision
receipts. Its canonical-JSON + DSSE Pre-Authentication Encoding + ECDSA-P256-
SHA256 signing style is derived from the SZL estate (szl-receipt,
khipu-consensus) and its receipt field names align with governed-receipt-spec,
all licensed under Apache-2.0.

It does NOT bundle or redistribute any third-party guardrail model weights
(Llama-Guard, NeMo-Guardrails, guardrails-ai, ProtectAI, etc.). Those are
integrated by reference through a user-supplied verdict object or callable.
