O03 · A seed-library key that needs a decision
FICTIONAL PLAN · deliberately ambiguous key
The supplied picture has an envelope shelf and an empty-envelope tray. A square marks each. Its printed key says square = envelope shelf AND square = empty-envelope tray. A pretend borrower asks which place holds envelopes to borrow. The key is ambiguous; the words label two different jobs. A child can propose a consistent new mark/word relation. This does not report a real library problem; no seeds are handled or swallowed.
