Library inventory

Count and classify library records while keeping unknown, unavailable and incomplete evidence visible.

Workflow

1. Choose inventory scopeName the library/copy and which completeness evidence is required.
2. Scan catalogue evidenceRead records and evidence without treating an inaccessible destination as empty.
3. Review uncertain resultUncertain, incomplete or user-sensitive results remain reviewable with their source identity and reasons.
4. Publish inventory reportReturn counts and named gaps tied to the inspected catalogue revision.
5. Return unavailableMissing prerequisites and unsupported inputs produce an explicit unavailable outcome without inventing a result.

Failure boundaries

• Drive offlineUnavailable records: Do not count zero
• Counts change mid-scanRevision changed: Restart/report partial
• Known ≠ category totalsReport invalid: Reconcile
