PDF compression handoff: state the quality checks

When handing off a compressed PDF, provide the source and output filenames, sizes, compression setting, and pages inspected for readability. Mention whether links, forms, bookmarks, and selectable text were tested, and flag any known image degradation. Keep the original available if the recipient needs a higher-fidelity version. The next person should know whether the file is a distribution copy or an archival master, rather than assuming smaller means equivalent.
