Reservation and admission

The parent loan carries the requested copy count. Loan-event lines record quantity, reservation time, admission time, a provider receipt and an attendee reference when those details apply. Each line has a number and revision, so staff can identify the exact part of the loan affected by a correction. The work should distinguish a reserved claim from an admitted or issued event.

The guarded custody action checks the authenticated organization, source identity, expected revision and actor scope before writing. It records an operation receipt with a stable key. A reservation is only complete when a verified provider capture exists. This creates a specific handoff between the person handling the copy and the person checking the provider effect.

• Capacity request. The loan’s copy count frames the quantity requested from the selected collection item.
• Reserved line. A loan-event line records the quantity and reservation timing under its parent.
• Admission event. Staff record the admission time and provider receipt on the line that actually moved.

Agree how line numbers are assigned, which staff member may reserve copies and what counts as an actual admission. Define the provider reference format that staff will record and the process for a missing receipt. Choose who compares reserved quantities to the parent’s copy count. The same organization and parent identity should be used in the reservation, provider evidence and operation receipt. Agree how staff will identify a partially admitted line so its remaining reservation is not mistaken for issued quantity.

A pilot should include a retry of the same action. The operation key should identify that attempt so a second click cannot issue another copy. It should also include a stale revision: if the loan changed after the operator opened it, staff need the current version before recording new custody activity.

A Loan Owner requests four copies for an event. The Admissions Coordinator reserves two lines against the approved loan, each with a quantity and line number. One line is admitted and receives its admission time and provider receipt. The other remains only reserved. If the event is cancelled, the unused reservation can be released, while the admitted line stays in the history. The Finance Reviewer confirms the provider capture before the operation is treated as completed.
