algovoi-refund-receipt-lite 0.1.1

Open, content-addressed refund references bound into the pinned AlgoVoi substrate (subject_ref + refund result + amount; closes the payment lifecycle after settlement; L1 frozen)

algovoi-refund-receipt-lite

Open, content-addressed refund references for the AlgoVoi substrate. The lite, Apache-2.0 origination tier of the commercial AlgoVoi Refund Receipt.

refund_ref = "sha256:" + SHA-256(JCS({ refund_amount, refund_result, subject_ref }))

It content-addresses the refund of a prior payment into a deterministic, recomputable reference:

• subject_ref: the payment/decision being refunded, imported by hash. Typically the guardrail_ref of the pre-payment decision or a settlement reference, so the refund composes onto the decision chain and closes the lifecycle after settlement.
• refund_result: a closed enum: FULL, PARTIAL, REJECTED.
• refund_amount: the amount returned, as a string ("0" for a REJECTED refund).

All three fields are byte-load-bearing: change the subject, the result, or the amount and the refund_ref diverges, so a refund cannot be silently re-pointed to another payment and neither the outcome nor the amount can be changed. A result outside the enum, or an empty subject_ref/refund_amount, is rejected, not hashed.

Use

from algovoi_refund_receipt_lite import refund_ref

ref = refund_ref(
    subject_ref="sha256:2a444c629892f44fde1bd004aba9be01dd6cc7fe251eecdd545b82dca9f0bf97",
    refund_result="FULL",
    refund_amount="1000",
)

Adopters (pin → key)

If you build on algovoi-refund-receipt-lite, pin ==0.1.0, anchor a canonical refund_ref vector hash from refund_receipt_lite_v1, and keep the NOTICE, you qualify for a free v0 licence key for algovoi-mandate-auditor. The gate is scripts/check_v0_adoption.py. Apply: email [e-mail] with your import-by-hash evidence and a copy of the NOTICE.

Conformance

The refund_receipt_lite_v1 vector set is published in the public corpus, chopmob-cloud/algovoi-jcs-conformance-vectors, with Python and Node runners. Python and TypeScript reproduce every value byte-for-byte. rf-001, rf-002 and rf-003 refund the ALLOW guardrail_ref in spend_guardrail_lite_v1 / spend_decision_chain_v1.
