Purpose: choose a sample that helps someone judge fit rather than merely admire a cover.
Question ledger: audience and task | uncertainty in their words | evidence source/date | product feature that could answer | authentic file/section | requirement or limitation | unanswered part. Distinguish actual buyer questions, internal assumptions, and fictional teaching scenarios.
Typical uncertainties: depth of instructions; whether one task can be completed; editable versus reading format; actual contents; required companion files/apps; saving behavior; device limitations; rights; what the buyer must supply. Choose the uncertainty most consequential for an informed purchase, not only the easiest attractive screenshot.
Evidence hierarchy: complete real included section; exact format demonstration; checked file inventory; bounded worked example labeled fictional; measured receiving task if actually performed. A mockup can illustrate appearance but cannot establish that the supplied file opens or behaves that way.
Constraints: third-party/client permissions; private information; content needed for meaningful context; accessibility and readable text; availability of the real artifact. If a rights or factual gate is unresolved, choose authorized original material or hold publication.
Decision: question selected [ ]; authentic evidence to show [ ]; what it establishes [ ]; what remains unproven [ ]; owner [ ]. Avoid promises of universal compatibility, commercial results, or research coverage not supported by checks.
