Library cards and quantum books

Classical photocopies can identify classical text. If a book denotes an arbitrary unknown quantum state, a classical card catalogue cannot return every amplitude and reference correlation from one copy. A quantum carrier must remain accessible for whole-code recovery.

A classical index can legitimately select a quantum branch decoder when an appropriate quantum output survives. It must not be renamed the quantum carrier itself. Emptying the named locked stack is an interface event, not proof of physical annihilation or a final energetic burst.
