A verifiable proof of filing, such as a timestamp receipt or a receiving office's acknowledgement, evidencing that a canonical fingerprint existed or an instrument was transmitted at a given time. Receipts are evidence of filing, never endorsement, adoption or recognition by anyone.
A deposit receipt is a verifiable proof of filing: a timestamp receipt, a delivery confirmation or an acknowledgement by a receiving office that evidences the existence of a canonical fingerprint or the transmission of an instrument at a given time. It is evidence of filing, not endorsement.
The framework's most repeated sentence is "receipts, not endorsements". Deposits and submissions can be documented as acts of transmission; recognition, adoption or incorporation remain entirely at the discretion of the receiving institutions.
Where instruments are transmitted to multilateral or public institutions, the transmission is an informational deposit or courtesy filing, logged as a docket, possibly accompanied by cryptographic integrity anchors. Silence, acknowledgement of receipt or archival processing does not constitute endorsement. Receipts and confirmations are logged if and when formally issued.
A deposit receipt creates no treaty status, no standing within the receiving institution, no intergovernmental status and no change to any legal framework. It is not the Machine Contact correspondence receipt, which evidences that IBQMI received a message.
