# Mock Refund

Compose refund quote, refund reserve, optional approval, and deterministic mock

refund settlement against a linked sealed charge receipt.

This graph profile is for local harnesses, demos, and contract tests. It does

not perform a live rail mutation or claim runtime refund enforcement.

## Quality Profile

- Purpose: show the provider-initiated refund graph for the mock family.

- Audience: operators, registry tooling, and future refund runtime

implementers.

- Artifact contract: `refund_quote_packet`, `refund_reservation_packet`,

`refund_approval`, and `refund_rail_packet`.

- Evidence bar: every step carries the original receipt ref and same settlement

family.

- Strategic bar: refuse cross-family refund shape in profile examples.

- Stop conditions: stop before settlement when original receipt link,

reservation, approval, or idempotency is missing.

## Inputs

- `original_receipt_ref` (required): linked sealed charge receipt reference.

- `original_receipt` (required): redacted original charge receipt summary.

- `refund_request` (required): requested amount and reason.

- `parent_payment_authority` (required): parent payment authority term or ref.

- `approval_context` (optional): prior approval evidence.

- `idempotency_seed` (optional): stable refund idempotency seed.
