Private prototype. Open a metadata list already prepared on your device. Nothing is uploaded or fetched automatically. No original source files belong in this format. It supports up to 20,000 rows, 25 MiB, and shows 50 rows per page.
Publisher and download host are separate. Download failures, registered review occurrences and OCR-quality reports are different kinds of work. These are gaps in verified holdings unless source-level evidence establishes otherwise. Evidence buckets are assertions from the imported list, not independent verification by this viewer. Row counts do not prove an unresolved arbitration backlog. This is a read-only view; it does not change decisions, source files or the registered queue.
Check evidence before contacting the source. Acquisition-gap URLs are displayed as text, without download or retry buttons. A failed attempt does not establish that the publisher lost a file. This viewer cannot coordinate independent visitors; shared probe claims, source-wide limits and cooldown enforcement require a separate service and are not implemented.
