This package is an adopter of the AlgoVoi substrate. It content-addresses the refund of a prior
payment (subject_ref + refund_result + refund_amount) into a deterministic refund_ref using the
substrate's canonical RFC 8785 JCS + SHA-256 hash. The canonicalisation base is imported by hash
and is not modified. The subject_ref is imported by hash and is typically the guardrail_ref of the
pre-payment decision (AlgoVoi Spend Guardrail (lite)) or a settlement reference, so the refund
composes onto the open pre-payment decision chain and closes the lifecycle after settlement.

This is the LITE (open, unsigned) tier. The commercial AlgoVoi Refund Receipt issues Falcon-1024
(post-quantum) signed receipts with provider, timing and jurisdiction flags, and closes the
original payment across the settlement and retention chains.

Canonical conformance vectors: conformance/refund_receipt_lite_v1/vectors.json (rf-001, rf-002 and
rf-003 refund the ALLOW guardrail_ref in spend_guardrail_lite_v1 / spend_decision_chain_v1).
