🟢get_receipt(decision_id)
RCO, the Record of Cleared Orders: the signed receipt of one cleared decision, by decision_id — what was cleared (a GTIN, an ISIN, a product id), for which actor class, under which rule and version, the records read, the signal, when, the issuing door, its signature and the ledger transaction id. Anyone, no account. No caller data, no PII, no amounts.

}🟡write_receipt(receipt)
Authorised doors only: x-door-key (a key issued by the office; the door receipt of plan v1.1 §2.6, signed by the issuing door) or x-hub-key (a GSC hub gate receipt). The hash goes on the Confidential Ledger; the receipt is kept and served by decision_id. Idempotent on decision_id.
