zooqueenandHanzo Dev a265087b13 No route makes or records a refund; a refund or dispute is recorded only from the processor's signed webhook, once, and an inquiry that closes without a chargeback restores its period
Commerce never initiates a refund. POST /v1/billing/refunds, POST /v1/billing/refund,
POST /v1/order/:orderid/refund and POST /v1/payment/:paymentid/refund are gone with
their handlers (engine.CreateRefund, checkout Refund, square.Refund) and the helpers
only they used; GET /v1/billing/refunds stays read-only. A claim is settled by a
replacement order, never a refund.

A refund or dispute of a plan's payment reaches its invoice only from the
processor's webhook, under the processor's own refund id, through one locked
writer that reads the invoice afresh (engine.RecordRefund, engine.RecordDispute).
Every state a dispute reports reaches the invoice; INQUIRY_CLOSED holds the
payment no longer, WON stays final and LOST stays disputed.

No backfill of the payment-to-invoice index is run: the only plan payments made
before v1.50.139 are the team's own card purchases (z24, zk) and one Square
record.
