This package is an adopter of the AlgoVoi substrate. It content-addresses the cancellation of a
spend authority (mandate_ref + cancellation_reason) into a deterministic cancellation_ref using
the substrate's canonical RFC 8785 JCS + SHA-256 hash. The canonicalisation base is imported by
hash and is not modified. The mandate_ref is the same mandate_ref produced by AlgoVoi Payment
Mandate (lite) and consumed by AlgoVoi Spend Guardrail (lite), so the cancellation composes onto
the open pre-payment decision chain.

This is the LITE (open, unsigned) tier. The commercial AlgoVoi Cancellation Receipt issues
Falcon-1024 (post-quantum) signed receipts with effective-from timing, provider and jurisdiction
flags, and propagates the cancellation across the settlement and retention chains.

Canonical conformance vectors: conformance/cancellation_receipt_lite_v1/vectors.json (cn-001,
cn-002 and cn-003 cancel mandate_1, the mandate_ref in spend_guardrail_lite_v1).
