It shows about 40 controlled sets total, with 19 on the shelf, 11 checked out in the field, 11 checked out in the field, and 8 overdue, and it replaces time-consuming paper logs by enabling fast search and overdue filtering. Each binder and redline set gets a QR label and every handoff is logged automatically with who, when, and why, as permanent append-only lines that cannot be edited or deleted. The system stores metadata only (no pictures or drawing content) and can generate an on-demand custody record for auditors, including an SSH 256 hash to prove the record was not altered."}
