During a criminal trial involving alleged procurement fraud, the prosecution seeks to admit a printed maintenance log from the airline's flight operations software showing the sequence of maintenance actions performed on the aircraft implicated in the offense. The original digital logs on the airline's secure server were overwritten during a system upgrade and cannot be retrieved. The airline's IT supervisor testifies that the printed log faithfully reproduces the entries at the time of printing, including timestamps and technician IDs. The defense objects that the original logs were not produced and questions the printout's completeness and integrity. The trial court admits the printed log on conditional grounds, stating it may be used only if the original logs are proven unavailable or properly authenticated; the copy remains provisional until those conditions are satisfied. (a) Identify the central doctrine governing conditional admissibility of secondary evidence in this context. (b) Distinguish the controlling rule regarding original versus duplicate evidence and the conditions for conditional admission. (c) Apply the doctrine to these facts: is the printed log admissible now? what must be shown to make it fully admissible, and what issues could still affect its reliability or weight?
