Attach proof of cover to a warranty
A provider lookup answers whether a unit is covered. It does not produce the invoice or the extended-warranty certificate, and a manually entered warranty had nowhere to keep one - so the proof stayed in somebody's mailbox until they left. Two columns rather than one: the served URL of the stored document, and the name the vendor sent it under, because "Dell invoice 4471.pdf" is what a person recognises a year later and "warranty-12.pdf" is not. The download route sends the original name back. Authenticated in both directions, unlike an asset photo: an invoice carries pricing and a service tag. One document per warranty, replacing any prior extension so a re-upload as .pdf does not leave the old .png behind claiming to be current. Capped at 25MB - a certificate is a document, not a disk image. Office formats are allowed because purchase records genuinely arrive as .msg and .xlsx, not only as PDFs.
