A credited extract is treated as unlimited permission

A fictional editor finds a freely readable article and a commissioned illustration. The team assumes that naming the author permits copying the complete article and that payment for the image automatically transfers every digital and print use. The proposed compilation also includes a translation and a modern annotated version of an older work. The actual agreements, rights categories and exception conditions have not been assessed. No content is published here. Identify the separate permissions and underlying contributions, explain why attribution and payment do not resolve every issue and distinguish a current statutory exception from an unverified rule remembered from an older law.
