Report an unexpected download, file-integrity, display, extraction, OCR or interpretation result. No OCR passage is required. This form does not repair files, retry downloads or upload anything. Keep originals and private records on your device.
Record what you observed; cause remains unknown unless evidenced. An unsupported reader/version, an HTML error page saved with a PDF extension, access restrictions and an incomplete download are different possibilities. A failure to open does not by itself prove corruption. Use UNKNOWN where a method version, file version or location cannot be established. Inspect the report before sharing. A hash is not identity, trusted time, permission or proof of diagnosis.
Reopening inspects the saved report without replacing your current draft. Source bytes are never embedded. Acquisition reports are not invitations for every reader to retry a source; coordinate first.
